BEIJING—Apple Inc is one step closer to beginning sales of iPad3 tablet computers with cellular (手机) network compatibility (兼容) for the first time in the Chinese mainland, where the consumer-electronics giant is in the midst of an aggressive expansion.
According to China’s Telecommunication Equipment Certification Center, a device by Apple with third-generation high-speed wireless data capabilities was issued the network access license needed for the company to begin official sales in China. The device, listed under model number “A1396”, is compatible with the 3G standard WCDMA, and would work with the cellular network operated by Apple’s local iPhone partner, China Unicom (Hong Kong) Ltd.
China Unicom declined (谢绝) to comment.
Apple already offers the 3G iPad3 in Hong Kong through its partners, but currently only offers Wi-Fi versions of the device in the Chinese mainland. Still, consumers in China, which according to research firm IDC surpassed (超过) the US as the world’s largest PC market in the second quarter, have been purchasing 3G tablets through unofficial channels.
Separately, Apple spokeswoman Carolyn Wu said Sept 6 that the company’s first Hong Kong store, set to open this quarter, will be located in the city’s central shopping and business district in the International Finance Center’s upscale (高档的) IFC mall, a commercial center and sightseeing spot along the city’s waterfront. Wu also said that Apple is planning a new store in Shanghai later this quarter, which will be its biggest store in China. She declined to give more details or to comment on the 3G iPad3.
Apple currently has four full-service Apple stores in the mainland, which receive the most traffic of any Apple stores in the world. The company otherwise relies on resellers to get its products into the market.
The new stores reflect Apple’s confidence in rising demand for its products such as smart phones and tablet computers. Sales in the Chinese mainland, Hong Kong and Taiwan helped boost (增长) the company’s third-quarter results, newly appointed Chief Executive Tim Cook said in July. China revenue (收益) surged (激增) six-fold to about $3.8 billion during the three months ended June 25.
“This has been a substantial (重大) opportunity for Apple and I firmly believe that we’re just scratching the surface right now,” Cook said at the time, referring to strong sales in China. “I see an incredible opportunity for Apple there.”

China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylamide glycol （ [化]乙二醇）, a low – cost substitute commonly used in automobile antifreeze（防冻剂）.
Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.
【小题1】Which of the following statements is TRUE according to the passage?

A．It has long been expected oxygen sensors exist in mice’s skin.

B．People have to surf the Internet to read detailed findings.

C．It has been proved that these findings help treat lung diseases.

D．Johnson believes that Oxygen sensors also exist in human skin.

【小题2】One of the functions of the molecules mentioned above is _______.

A． increasing level of oxygen	B．improving athletes’ performance
C．detecting oxygen	D．carrying oxygen around the body

【小题3】What is Johnson’s attitude to the application of the findings to the athletes’ training?

A． Hesitating

B．Doubting

C．Positive

D．Negative

【小题4】The best title of the passage may be _______.

A． Humans Might Sense Oxygen Through Skin

B．Frogs And Mice Are Distant Relatives

C．First Known Animal Breathes Through Skin

D．Great Findings Benefits Athletes A Lot

The long, lonely voyage of the Japanese ghost ship is over.
A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year’s tsunami (海啸), sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed to shipping and the coastline on Thursday.
The cutter’s guns tore holes in the 164-foot Ryou-Un Maru, and then it began to take on water and lean to one side. In about four hours, the ship disappeared into the sea, said Chief Petty Officer Kip Wadlow.
The ship had no lights or communications system, and its tank was able to carry more than 7,570 liters of diesel fuel. Officials, however, didn’t know exactly how much fuel was aboard.
“It’s less risky than it would be running into shore or running into other ships,” coast guard spokesman Paul Webb said.
The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it is safer to sink the ship than let the fuel evaporate and pollute the sea environment.
Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of refrigerators, washing machines, televisions, roofs and fishing nets heading toward North America since last March when a magnitude-9.0 earthquake struck Japan.
As the coast guard was ready to fire on the vessel, a Canadian fishing vessel, the 19-meter Bernice C, claimed the rights to save the ghost ship in international waters.
Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it.
Then the Canadian boat left, and once it was about 10 kilometers from the Japanese vessel, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition (弹药)twice that size.
State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant, to see if Alaska residents, seafood or wild animals could be affected.
【小题1】The plan to fire on the Japanese ghost ship was paused because ____________.

A．the ghost ship was beyond the reach of the Coast Guard’s guns

B．state officials worried the ghost ship might give out radiation

C．the shells were not powerful enough to sink the ghost ship

b. The US Coast Guard sank it into the sea.
c. The ship began to float across the Pacific Ocean.
d. A big tsunami was caused by great earthquakes.
e. Bernice C claimed rights to save the ghost ship.

A．d, c, e, b, a

B．a, b, d, c, e

C．c, e, d, a, b

D．b, a, d, c, e

【小题3】Which of the following could be the best title for the passage?

A．Japanese ghost ship arriving at US

B．Tsunami garbage heading to US

D．Cannon fire sinking Japanese ghost ship

●Ms Tan, you’ve referred to your new novel as your eighth book.
That’s because it took me six or seven attempts at a second novel before I started and completed this one.
●Why do you think you had so many false starts?
I would say that my reasons were wrong. I was trying to prove that I wasn’t just a mother-daughter storyteller, or I was trying to prove that I didn’t just have to write about things that were strictly Chinese or Chinese-American. Those were never the right reasons for writing those early stories. And I could never come up with other better reasons for continuing them.
●What kept you going on this book?
This book was different because it was based on my mother’s real life. The reason for writing it became more personal and emotional. After The Joy Luck Club came out, my mother was always explaining to people that she wasn’t any of the mothers in that book. And at one point she said to me, “Next book tells my true story.” And then she started telling me things I never knew before. She also told me many, many stories, because my mother doesn’t generalize(笼统地表达). The book really grew out of that.
●Have you ever visited China?
Yes. I’ve been there twice: about three years ago and then again last November, both times with my mother and my husband.
●Was it difficult to understand the Chinese-American dialect(方言) without sounding like a parody(拙劣的模仿)?
No, because it’s the language I’ve heard all my life from my mother. She speaks English as it’s direct translation from Chinese. But it’s more than that. Her language also has more imagery than English.
●Can you think of an example?
Somebody might say to me, “Don’t work so hard. You’ll kill yourself.” My mother will say to me，“Why do you press all your brains out on this page for someone else？” So it’s very vivid. That’s the way she talks.
●Have many readers told you that the Chinese mother in your book reminded them of the typical Jewish (有癖好的) mother?
Many people have told me that. I think the mother-daughter relationship is very intense(紧张) in both cases. Culturally there is an acceptance that mothers have the power to tell their children, especially their daughters, how to conduct their lives --- not simply up until the time they are 18, but for the rest of their lives. However, when children grow up in a different culture from their parents’，they tend to keep more secrets from their parents. The children think, “They just wouldn’t understand that I had to do this.” And that can really create a gap, and it can grow as the number of secrets grows.

Every few years, two groups carry out a study of how many Americans wash their hands after using the toilet. These groups are the American Society for Microbiology and the American Cleaning Institute, formerly the Soap and Detergent Association.
There was good news in the latest study. Researchers found that eighty-five percent of adults washed their hands in public restrooms last month. That was the most since the studies began in 1996.
Researchers visited restrooms at a baseball park in Atlanta and a science museum and aquarium(水族馆) in Chicago. They also visited two train stations in New York City and a large farmers’ market in San Francisco. In all, they observed about six thousand adults, with females and males equal in number.
The researchers found that seventy-seven percent of men and ninety-three percent of women washed their hands. That was up from sixty-six percent of men and eighty-eight percent of women in the last study three years ago.
The lowest rate of hand washing among men was at Turner Field, home of the Atlanta Braves baseball team. Only sixty-five percent of men washed their hands, compared to all but two percent of women.
Chicago and San Francisco had the most hand washers—eighty-nine percent of adults. Atlanta followed at eighty-two percent. New York had the lowest rate, at seventy-nine percent of the adults observed at Grand Central Station and Penn Station.
The findings of the observational study conflicted(不一致) with the findings of a separate telephone survey of about one thousand people. Ninety-six percent of them said they always washed their hands after using public restrooms.
Almost nine out of ten also said they always washed after using the bathroom at home.
Hand washing can help prevent the spread of many different infections.
To clean your hands well, wet them first and rub in soap for at least twenty seconds, including between the fingers and under the nails. Then wash under running water. In a public restroom, if you dry your hands with a paper towel, you should also use the towel to shut off the water and open the door.
Hand washing is also important when preparing food and after changing a baby’s diaper(尿布). You should also wash if you cough or sneeze into your hands.
【小题1】According to the latest study, about ____ women washed their hands after using public bathroom.

A．1,980

A couple of years ago, before a trip to China, Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.
“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,” said Davis.
Known as the “Iron Hammer” for her punishing spikes(扣球), Lang made it possible for China to dominate in the sport in the early 1980s. She was a key player on China’s 1984 Olympic gold medal winning team.
When the US team arrived for the Olympics, Lang, 48, who is from Beijing, had to take a different route to avoid a crowd of reporters and fans.
Then came the greatest moment to Lang：while the US team was playing in a packed gym, at least 8,000 Chinese fans unfurled an American flag.
“That really says it all,” Davis said. “They look at her as an icon(偶像)．I’m sure it’s hard for them to see her coaching another country, but they love her so deeply that her success is their success.”
The loyalty of the Chinese fans was tested on Friday, when China lost a match to the US.
“It’s a pity that China lost the match, but I’m still glad that Lang Ping’s team won, since she is the pride of China’s volleyball,” said Liu Chengli, a spectator. “We also cheered for Lang’s victory.”
Lang said she just tried to stay professional when the two teams meet. “It doesn’t matter if we play China or any other team. It’s the same.” Lang said.
Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players, said a US volleyball player Lindsey Berg.
“It’s such an honor to be here and play for our coach here in China,” she said. “The amount of support that the Chinese give to her and us has been tremendous. The whole event has been unbelievable.”
【小题1】What’s the passage mainly about?

A．Staying professional.	B．Cheering for the Iron Hammer.
C．A match between China and the US.	D．Lang Ping’s career as a coach.

【小题2】Lang Ping avoided meeting the reporters and fans probably because she ________.

D．didn’t want to disturb public order

【小题3】What does the underlined word “unfurled” exactly mean?

A．destroyed completely	B．tore into pieces
C．spread out to the wind	D．rolled up

【小题4】What does Lang Ping mean by saying “It doesn’t matter if we play China or any other team.”？

A．American Volleyball Team will beat any team.

B．Chinese Volleyball Team is the same as other teams.

C．She just tried to stay professional.

D．The results of each match will be the same.

【小题5】What impressed the US team players most?

C．Lang Ping’s coaching skills.	D．The loyalty for volleyball of the Chinese.

Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人员) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(评论家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.
【小题1】Paying students who show improvement in tests __________.

A．has been done in most American schools

B．is becoming a growing practice in the USA

C．is not very popular with teachers

D．only aims at high scores at school

【小题2】According to the text, Robert Schaefer _____________.

A．is a very excellent teacher

B．thinks highly of paying students

C．thinks students will show improvement in study in the future

D．thinks people should make a careful plan for the paying program

【小题3】From the last paragraph we can see __________.

A．EBCWRU has got great success in its paying program

B．not all the students in EUCWRU have made progress in all subjects

C．only students who study math can get paid

D．EBCWRU will go on with the paying program

【小题4】The text is mainly written to _____________.

A．persuade teachers to give students more prizes

B．tell people how to become an excellent student

C．introduce something about American paying students program

D．explain the advantages of American paying students program

Sometimes there doesn’t seem to be enough rain. Other times there is too much. Maybe thereisn’t a lot we can do to control the rain, but there is a lot we can do to reduce problems caused bydifferent rainfall patterns.
A new development at the London Wetland Centre in Barnes solves the problems of managingwater with a “Rain Garden”. We are likely to be hearing about it a lot more often over the next fewyears. The idea is that the garden owner can store rainwater and use it in dry periods. They canreduce the problems caused by extra rain this way.
One of the key problems that the rain garden tries to deal with is the problem caused by toomuch water in the street. In a natural environment, a lot of rainwater is sent back into the air byplants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happensin city environments can be completely different —— a large amount of rainwater flows straight offthe hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into theground —— floods are the result. Rainwater running off roads is often polluted.
The rain garden deals with living plants rather than hard surfaces. Plants are designed to holdwater and release it slowly, either into the ground, to be absorbed by plant roots (and so eventuallyback up into the atmosphere) or to go down into the water table. Not only does the rain gardenreduce the amount of water that flows onto the street, but it helps to clean it because plants are very goodat breaking down pollutants(污染物).
【小题1】What’s the main idea of the first paragraph?

A．Explaining why there is a lack of rain at times.

B．Introducing several different patterns of rainfall.

C．Telling us how to avoid problems caused by rain.

D．Giving the idea that there are ways to manage rain water.

【小题2】According to the second paragraph, “Rain Gardens" are likely to _____.

A．harm the environment in the short run

B．become popular over the next few years

C．be turned down by most new developments

D．be too expensive for common people to accept

【小题3】We can learn from the third paragraph that _____.

A．floods are often the results of small rains

B．a heavy rain is less difficult for plants to absorb

C．the rain garden helps send rainwater back into the air

D．larger amounts of rainwater flow straight off in city environments

【小题4】According to the last paragraph, what does the rain garden help to clean?

A．The plants

B．The ground.

C．The water.

D．The street.

As Apple tries to maintain its growth and success in China, the world's largest smart-phone market is becoming even more critical. Apple's shares(股份) fell sharply as the company's earnings for the holiday quarter through December disappointed investors.
The sales of the iPhone, which include both the iPhone 5 and older models, came in at the low end of analysts' expectations, while the company's income plan for the second quarter was below analysts' forecasts, though Apple is known to give conservative (保守的) forecasts.
Some analysts have said that for Apple to regain its growth, the company needs a more aggressive strategy(进攻型策略) for markets, or more specifically for China, where the market for smart phones has been expanding more rapidly than anywhere else. In China, demand is particularly great for inexpensive phones that run on Android(安卓) operating system, sold by many Chinese phone makers as well as South Korea's Samsung Electronics Co.
But Apple says it's already enjoying strong growth in China. "We saw big growth in iPhones," Chief Executive Tim Cook said. He said that the company has been quickly expanding its sales channels in China, including the number of Apple stores. "This isn't nearly what we need, we're not even close to that, but we're making great progress.” he said.
In China, a big missing piece for Apple is China Mobile Ltd. , the biggest local telecom carrier that doesn't yet sell the iPhone. Earlier this month, Mr. Cook met China Mobile Chairman Xi Guohua in Beijing and discussed cooperation, stirring hopes that the world's largest mobile carrier may soon start offering the iPhone.
Earlier this month, the Wall Street Journal reported that Apple is working on a lower-end iPhone that could launch as early as this year. But one possible challenge for Apple in China is that low-priced Android-based phones are getting better in terms of quality. A report from CLSA in late November showed that many smart-phones sold at about1,000 yuan ($160) came with higher- resolution screens, better cameras and more powerful processors than phones at that price did a year earlier.
【小题1】Apple's shares dropped sharply because in December______________.

A．the iPhone wasn't popular in China

B．its product quality was widely criticized

C．the earnings for the holiday quarter was disappointing

D．the investors were not satisfied with Apple's management

【小题2】What can we learn from the passage?

A．Apple tends to offer a lower sales forecast.

B．China Mobile Ltd began to team up with Apple.

C．Cook is pessimistic about what Apple did in China.

D．Apple didn't take measures to develop Chinese market.

【小题3】The author uses the report from CLSA to prove         _____.

A．their prices are actually lower than a year earlier

B．Apple in China has ability to deal with any problem

C．low-ended Android-based phones are progressing fast

D．the promotion of lower-end iPhone will face a challenge

【小题4】The main purpose of the passage is to show the readers ______________.

A．Apple's high popularity in China

B．the challenge Apple faces in China

C．the approaching failure Apple will suffer in China

D．Apple's aggressive strategy in its market expansion
