Many people cannot start their day without first having a cup of coffee or tea．These drinks help them think clearly and feel more awake．This is because of caffeine，which helps to give a jump start to the nervous system．Now，a report says it may also boost long-term memory．

Mike Yassa is a neurobiology professor．He and other researchers wanted to know if caffeine could improve a person’s memory．He explains，“After you learn anything，it takes some time for that memory to strengthen．And over the first 24 hours is actually where most of　　 the forgetting happens．So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting．”　　

They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house， or outdoors．Then some of the subjects were given a caffeine pill．The others were given a placebo—a pill containing nothing. 24 hours later，the subjects were shown the exact same images from the day before．They were also shown images with slight differences，and some completely new images. Both groups correctly identified the exact same and completely new pictures．But those who took the caffeine pill were better at spottingthe pictures that were slightly different．

Professor Yassa says their answers helped to show the effects of caffeine on memory. And　 we find that if they are on caffeine they are much more likely to make the right decision．”

Modern society cannot well do without the contribution that women can make in the professions and other kinds of work. There is a serious shortage of nurses and teachers, to mention only two of the occupations followed by women. It is a waste to give years of training at public expense only to have the qualified teacher or nurse marry after a year or two and be lost forever to her profession. The training, it is true, will help her in her duties as a mother, but if she continued to work, her service would be more widely useful. Many factories and shops, too, are largely staffed by women, many of them married. While here the question of training is not so important, industry and trade would be seriously short of staff if married women did not work.

We can see then that there are good reasons for regarding it as desirable that married women should have some occupation outside the home. However, there are serious objections. Schools do not keep children occupied the whole day and school holidays are long. The mother’s working day will almost certainly end well after the school day and her holiday will not begin at the same time as her children’s. There will be therefore a period when children are not taken care of unless a substitute for the mother can be found, or unless it becomes more generally possible for women to work part-time. There seem to be some grounds for believing that there is more bad behavior among the children of working mothers than among those of mothers who stay at home, but more evidence is required before we can be certain of this. What we can be certain of, however, is that many more will continue to do so.

1.According to the writer, women nurses and teachers ought to carry on their occupation after marriage because______.

A. they are not allowed to give up their jobs

B. their training should not be wasted

C. they want to make a living by themselves

D. they must still improve themselves as mothers

2.According to the writer, one possible way for the children of working mothers to be attended to is that________.

A. schools keep children occupied the whole day

B. their mothers change their occupation

C. their mothers do not work full time

D. their mothers should stay at home

3.The clause “unless a substitute for the mother can be found” means_______.

A. if someone takes over the mother’s occupation

B. if no mother works all day

C. if no one takes care of the children for the mother

D. if someone takes care of the children for the mother

4.The writer believes that bad behavior among the children of mothers who do not work is _________ among the children of working mothers.

A. possibly less than   B. about the same as

C. a little greater than   D. certainly more than

Qian Xuesen is one of the pioneers of China's space science. As a world-famous expert on aerospace rockets and aerodynamics, he obtained great achievements in the areas of applied mechanics, engineering cybernetics and system engineering and made distinguished contributions to the foundation and development of Chinese aerospace undertaking(事业).

He graduated from Shanghai Jiaotong University in 1934, and Qian Xuesen went to the United States to study in MIT, Massachusetts Institute of Technology, one year later. After receiving master's degree in MIT, he went to study in California Institute of Technology and received PhD degrees in both aerospace and mathematics.

In 1955, six years after the founding of People's Republic of China, Qian Xuesen returned to his motherland. His return brought China the hope of developing space science and its own missiles. In 1956, Qian Xuesen put forward “Proposal on the Development of China's Aviation Industry for National Defense”. With the support from Zhou Enlai, the premier, and marshal Nie Rongzheng, Qian Xuesen began to prepare for the establishment of China's first missile and rocket research and development structure, the Fifth Research Institute of State Ministry of Defense. Henceforth(从此以后), he has long been in charge of the chief technological research and development of China's missile, rocket and spacecraft.

Due to research and development led by Qian Xuesen, China successfully exploded its first atom bomb in 1964. Later, China launched its first man-made satellite, Dong Fang Hong I, to the earth orbit on April 24, 1970, becoming the fifth country in the world to independently launch satellite following the former Union of Soviet Socialist Republics, the USA, France and Japan. The satellite floated around the earth, blaring(高声播放)the song Dong Fang Hong, which has the same name as the satellite.

As a forerunner leading the development of China's aerospace science and technology, Qian Xuesen also provided chances for young scientists. Wang Yongzhi, former chief designer of China's manned-space project, has benefited a lot from Qian Xuesen. “He suggested that rocket of the second generation should be developed by our second generation scientists. This suggestion gave us chances to be general designers.” Recalling the experience working with Qian Xuesen, Sun Jiadong, general designer of China's lunar orbiter project, is very grateful. “He put great expectation on us and trusted us a lot. Whenever we made mistakes, he seldom blamed us, but helped us to find out the reason so we could avoid it in the future.”

Honored as Father of China's Missile and King of Rockets, Qian Xuesen never stopped his work on scientific research after he retired. He said he had no time to review the past, but looked forward to the future.

1.When did Qian xuesen begin to study in Massachusetts Institute of Technology?

2.Which of the following is about the five countries that launched man-made satellite independently before 1970?

3. What does the underlined word “forerunner”(Paragraph 5) probably mean?

4.According to the passage, which of the following about Qian Xuesen is NOT true?

5.It can be inferred from Paragraph 5 that _________.

Liu Qian, a magician from Taiwan, cast his spell(魔法)over an audience of thousands on the CCTV Spring Festival Show. Die-hard fans are still trying to work out the secrets behind many of the tricks he performed.

But Liu, 32, when asked, laughed off the idea that there might be an “answer” to his magic. “The most fascinating things about magic is the puzzling process. People enjoy how magicians make the impossible come true,” said Liu.

Few people today believe in the possibility of real magic. They also often fail to consider magicians’ devotion to their art. It can take a magician years’ of practice to perfect a trick before he performs it on stage.

Part of Liu’s star appeal is his astonishing skill. However, when he began in the industry, he was embarrassingly clumsy. “I could practice thousands of times for one single act. It wasn’t much fun,” he said.

No magician’s supernatural powers on stage extend to their life off stage. Liu says his life was no easier or funnier because he was a magician.

He developed an interest in magic at a young age, but didn’t consider making a living out of it until he graduated from university. He had studied Japanese language and found himself unable to find a job. “My parents never considered being a magician as a proper job. To begin with, I had little confidence I would be doing this in the long term,” he said.

Yet Liu felt a powerful calling to become a magician. “For many people, magic somehow means a miracle, which is something we all secretly wish for no matter how hard-bitten or cynical (愤世嫉俗的)we become,” he said.

Liu may be right. A popular modern dream is of the fairy godmother, who waves her magic wand (棒) and makes our dreams come true. But according to Liu, we all have the power to create magic in our lives. As Liu puts it: it’s not the magic that makes it work；it’s the way we work that makes it magic.

1. According to the passage, we can tell that ________.

A. being a famous magician, Liu Qian leads a comfortable life

B. it is a hard job for magicians to perform magic tricks well

C. Liu Qian’s parents supported his wish of earning a living by being a magician

D. Liu Qian showed great talents in performing magic tricks when he first took it up

2. As to whether there’s real magic, Liu Qian believes ________.

A. there is no real magic and what counts in our life is the way we work

B. if we secretly wish for something, magic will turn out to be a miracle

C. the puzzling process of performing magic tricks is the answer to magic

D. there exists a fairy godmother waving her magic wand to make our dreams come true

3. Which of the following sayings is similar to the underlined sentence in meaning?

A. All roads lead to Rome.                B. Easier said than done.

C. Actions speak louder than words.       D. Where there is a will, there is a way.

4. What is the best title for the passage?

A. Magic in our lives                     B. The answer to magic

C. A popular magician from Taiwan         D. The way to become a successful magician
