Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil（不存在）, many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne（升空的）.
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply（遵守）with much stricter regulations and are tested more regularly to make sure they still comply. Also, in t he unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious（重复的）, but it's worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence（气流）.
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.
【小题1】Whom is the passage meant for?
| A．Pilots. | B．Flight attendants. | C．Passengers. | D．Airlines. |

On the day Apple debuted the often-delayed white-colored iPhone 4, the company’s marketing department gave a nod to the product’s troubled history.
“Finally.” read the big headline Thursday above a picture of the white phone on the homepage of Apple. com.
The white model was supposed to ship alongside the black one at the iPhone 4’s launch（推出） last June. But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.
As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash（闪光灯） was used. Its whiteness confused the proximity sensor （距离传感器） , which detects when the phone is held next to someone’s head and turns off the touch screen to save battery life.
These problems weren’t present in older iPhones that came in white because they didn’t have flash photography; the proximity sensor was unaffected because the front side of previous models was black.
“We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren’t,” Philip Schiller, Apple’s chief marketing executive, said in an interview. “It’s not as simple as making something white. There’s a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors. “
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple’s phones. He says Apple could sell 1 million to 1. 5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.
Forty-five people were lined up at Apple’s flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.
【小题1】
The reason why white-colored iPhone 4 was delayed by 10 months is that _______.
| A．it’s always sold out due to its popularity |
| B．it met some problems concerning design and manufacture |
| C．it lacked white manufacturing materials |
| D．its proximity sensor can’t save battery life |
| A．There are multi-colored models of iPhone 4. |
| B．The same design problems were also found in older white iPhones. |
| C．IPhone4 will be launched this fall. |
| D．Originally designers thought they could solve the problems before iPhone 4 was launched. |
| A．Why the White iPhone 4 Took So Long |
| B．The History of iPhone 4 |
| C．The Attraction of White iPhone 4 |
| D．The Design and Manufacture of iPhone 4 |
| A．to remove one’s mask from his face |
| B．to remove a cloth from something, especially as part of a ceremony |
| C．to show to the public for the first time |
| D．to disappear from the public for the first time |

A controversial new study has claimed that men really are more intelligent than women．The study concluded that men’s IQs are almost four points higher than women’s.
British-born researcher John Philippe Ruston says the finding could explain why so few women make it to the top in the workplace.
He claims the “glass ceiling” phenomenon is probably due to inferior intelligence，rather than lack of opportunity.
The University of Western Ontario psychologist reached his conclusion after scrutinizing the results of university ability tests taken by 1 00,000 students aged 17 and 18 of both sexes.
A focus on the factors such as the ability to quickly grasp a complex concept，verbal reasoning skills and creativity― some of the key factors of intelligence ―showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100.The findings，which held true for all classes and levels of education, overturn 100 year opinion that men and women average the same in general mental ability. They also conflict with evidence that girls do better in school exams than boys.
But Professor Ruston argues that the faster maturing of girls leads to them outshining boy in the classroom.
【小题1】 The report is mainly about ______.
| A．a study that shows men are cleverer than women |
| B．the “glass ceiling” phenomenon |
| C．Professor Ruston’s theory on IQ |
| D．the difference between male and female |
| A．making up | B．carrying out | C．examining carefully | D．looking at |
| A．a little less than 100 | B．100 |
| C．more than 100 | D．96.37 |

An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.
【小题1】 What’s the purpose of the new product?
| A．To inform us of the new car system. | B．To introduce some improvement in cars. |
| C．To limit certain drivers to safe driving. | D．To popularize the built-in car system. |
| A．the project of the built-in product | B．why the system becomes popular |
| C．the functions of GPS in cars | D．how the product is programmed |
| A．Most of the traffic deaths can be avoided. | B．Speeding violations can be easily found out. |
| C．The system will excite some teenage drivers. | D．The product will not be available for adults. |
| A．Speed Alert and Its Future Use. | B．Progress in Car-making Science. |
| C．Warning for Adventurous Drivers. | D．New In-Car Device against Speeding. |

With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills（泄露） on people, nature, and the environment．
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．
Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．There are, of course, long-term effects, but it is usually more serious in the short term．
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible．In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
We should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太阳能）, electricity, hydrogen, and so on．Much of this research has, in the past, been held back by the oil, gas, and coal．
If the world’s millions of cars were 10% more efficient（高效的）— and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．
【小题1】What is the passage mainly talking about?
| A．Oil tanker accidents． | B．Oil spills pollution． |
| C．What oil pollution is． | D．How to reduce oil pollution． |
| A．By giving a description． | B．By making an argument． |
| C．By giving an example． | D．By drawing a diagram． |
| A．Transportation depending more on oil． |
| B．Poisonous oil breaking down naturally． |
| C．Millions of tons of oil spilling into the sea． |
| D．More environmental damage being caused． |
| A．We should develop new technologies to cut oil use |
| B．Tankers should not be allowed to sail near the coastlines． |
| C．We should build safer oil tankers in the near future． |
| D．Countries should build more oil pipelines under the sea． |

At one time, computers were expected largely to remove the need for paper copies of documents (文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down," says Ted S
mith of the Earth Village Organization.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.
Does all this mean environmental concerns (环境问题) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. " I guess people believe that the problem is taken care of, because of recycling (回收利用) " said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
【小题1】 The growing demand for paper in recent years is largely due to ________.
| A．the rapid development of small businesses |
| B．the opening up of new markets |
| C．the printing of high quality copies |
| D．the increased use of the Internet |
| A．to encourage printing more quality documents |
| B．to develop new printers using recycled paper |
| C．to find new materials for making paper |
| D．to plant more fast-growing trees |
| A．people are concerned about the environment |
| B．printers in many offices are working overtime |
| C．small companies need more hard copies |
| D．they see a growing market for printers |

Science has told us too much about the moon that it is fairly easy to imagine what it would be like to get there. It is certainly not a friendly place. Since there is no air or water, there can be no life of any kind. There is not much variety of scenery either. For mile after mile there are only flat plains of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountain shadow, it means moving from the severe cold into intense (强烈的) heat. These extreme temperatures continually break rocks away from the surface of the mountains. The moon is also a very silent world, for sound waves can only travel through air. But beyond the broken horizon, you see a friendly sight. Our earth is shining more brightly than the stars. From this distance, it looks like an immense (巨大的) blue, green and brown ball.
【小题1】The moon is an unfriendly place because .
| A．there is no air, no water, no life, no scenery | B．the sun and stars shine in the sky |
| C．temperature breaks rock away | D．all of the above |
| A．man | B．air | C．sound | D．water |
| A．the earth looks like a colored ball |

PALO ALTO, California------"Switching off the television may help prevent children from getting fatter------ even if they do not change their diet or increase the amount they exercise," US researchers said last week.
A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.
【小题1】The author tries to tell us in the first two paragraphs that ________.
| A．children will get fatter if they eat too much |
| B．children will get thinner if they eat less |
| C．children will get fatter if they spend less time watching TV |
| D．children will get fatter if they spend more time watching TV |
| A．is more than four hours a day | B．is less than four hours a day |
| C．doubled in the last twenty years | D．is more than on any other activities |
| A．six hours | B．eight hours | C．three hours | D．one hour |
| A．Children usually eat fewer while watching TV. |
| B．Children usually eat more while watching TV. |
| C．Children eat the same amount of meals while watching TV. |
| D．Children usually eat nothing while watching TV. |

As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets sage. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of ho
w extensive the wasted electricity is worldwide.
Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.
【小题1】The author tells the story in the second paragraph mainly to _________.
| A．remember the past beauty of the town. |
| B．stress the advantages of less pollution |
| C．show the great changes of the town |
D．prove the bad effects of li ght pollution |
| A．to try to reduce unnecessary light. |
| B．not to ignore the beauty around. |
| C．to set proper light for animals |
| D．not to destroy the animal’s living conditions. |
| A．Light pollution is difficult to deal with. |
| B．Light pollution is a threat to some animals. |
| C．Light pollution has nothing to do with global warming |
| D．Astronauts can’t see clearly in space due to light pollution. |
agraph?| A．The author’s contribution to light pollution |
| B．Other sources of light pollution |
| C．Ways of reducing light pollution |
| D．More bad effects of light pollution |
