The dream of flying into outer space, cherished by the Chinese people for centuries, will soon come true.
China launched its fourth unmanned spacecraft (飞船)“Shenzhou Ⅳ” on December 30 at the Jiuquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive(连续的 )and successful launch of China - made rockets since October 1996. This launch has made it more realistic for China to send a person into space on its own following Russia and the USA.
Qi Faren,leading designer of the spacecraft system, said all the functions (功能) designed for manned flights have withstood (经受住)the test of three previous, successful launches and return landings of the “Shenzhou” spaceships.
China launched the “Shenzhou Ⅰ ”, “Shenzhou Ⅱ ”and “Shenzhou Ⅲ ”spacecrafts in 1999,2001 and 2002 respectively.
“Shouzhou Ⅳ” was to make it a more comfortable place in which astronauts can live and work. All parts of the application system for manned flight are aboard the “Shenzhou Ⅳ”craft in all test flights.
China’s manned flight programme began in 1992. A number of unmanned test flights will be launched before Chinese astronauts are sent into space.
Leading scientists in charge of China’s manned space programme said the successful launch of the “Shenzhou Ⅳ” laid a solid foundation for the country’s future task of sending Chinese astronauts to outer space.
The spacecraft returned to the earth on January 5, after completing seven experiments in space.
Officials at the centre said that“ Shenzhou Ⅴ”, a manned spacecraft, is expected to be launched later this year.
How many countries can send a person into space on its own by now?
A. 2. B. 3.
C. 4. D. Not mentioned.
China’s manned flight programme began in ________.
A. 1992 B. October 1996.
C. 1999 D. January 2003
As a matter of fact, ________ .
A. “Shenzhou Ⅴ ”has been launched
B. “Shenzhou Ⅳ” was a manned spacecraft
C. “Shenzhou Ⅲ ”and“ Shenzhou Ⅳ” were not launched in the same year
D. the dream of man flying into outer space has come true in China
Which is the most suitable title for the passage?
A. The Successful Launching of “Shenzhou Ⅳ ”.
B. The Landing of “Shenzhou Ⅳ ”.
C. Chin a’s Manned Flight Programme.
D. The Third Country Sending a Person into Outer Space.

“It hurts me more than you,” and “This is for your own good.” These are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.
That was before we entered the permissive(自由的) period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy on us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation.
Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake. One such teacher is Sharon Klompus who says of her students—“so passive”—and wonders what happened. Nothing was demanded of them, she believes. Television, says Klompus, contributes to children’s passivity. “We’re not training kids to work any more.” says Klompus. “We’re talking about a generation of kids who’ve never been hurt or hungry. They have learned somebody will always do it for them, Instead of saying ‘go and look it up’, you tell them the answer. It takes greater energy to say no to a kid.”
Yes, it does. It takes energy and it takes work. It’s time for parents to end their vacation and come back to work. It’s time to take the car away, to turn TV off, to tell them it hurts you more than them but it’s for their own good. It’s time to start telling them no again.
67.To such children as described in the passage __________.
A. neither is easy to say yes or say no
B. it is easier to say no than to say yes
C. it is easier to say yes than no
D. neither is difficult to say yes or say no
68.We learn from the passage that the author’s mother used to lay emphasis on(强调;重视) ________.
A. natural development B. education at school C. learning Latin D. discipline
69.By “permissive period in education” the author means a time ________.
A. when everything can be taught at school
B. when children are permitted to receive education
C. when children are allowed to do what they wish to
D. when every child can be educated
70.The main idea of the passage is that _______.
A. It’s time to be more strict with our kids
B. parents should always set a good example to their kids
C. parents should leave their children alone
D. kids should have more activities at school
Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health.
This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased.Apple, for example, doesn’t want iP hones to come closer to you than 1.5 centimeters; Research In Motion, Blackberry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the implications are huge.Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - generate $109 billion for the wireless carriers.
Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.
