  在阅读过程中,我们可以根据生词的构词线索来推测该词的词义,这也是一种积极有效的阅读策略。《英语课程标准》中的“语法项目表”规定我们需要了解的构词法有合成法、派生法和转换法三种。由两个或两个以上的词合成一个新词,称为合成法,如world+wide→worldwide(世界范围的)等。在一个单词(词根)前后加上词缀,构成一个新词,叫派生法,如unwillingly(不愿意地)和comfortable(舒适的)。转换法是将一种词类转变为另一种词类,如Father eyed me seriously.(父亲严肃地盯了我一眼)等。


  Passage A


  Chinas first astronaut Yang Liwei walked out of the return capsule (舱) of the Shenzhou 5 spaceship, smiling and waving to the waiting people. Thursday morning in the grasslands in Gobi Desert, Inner Mongolia, state television pictures showed.

  Yang has spent 21 hours in outer space, travelling more than 600,000 kilometers in the earths orbit (轨道) before Shenzhou 5 brought him back at 6:07 a.m. Thursday morning Beijing time. Yang said he feels excellent after the 21hour journey, the first by a Chinese.

  Chinese Premier Wen Jiabao said in a congratulation message Thursday morning that Chinas first manned spaceflight has been a “complete success”, which shall be written into the history of Chinas space program development.①

  After Yang went out of the capsule, doctors offered a physical checkup to Yang at once, which found him in good conditions. At about 7∶40 a.m., Yang was carried by a helicopter (直升机) to Beijing, where a celebration party will be held.

  At about 6:00 a.m. Thursday, the return capsule of Shenzhou 5 entered Chinas air space. Several minutes later, the capsule landed safely in Northwest Chinas Inner Mongolia Autonomous Region,② and Yang reported “The conditions are good”.

  Five rescue helicopters went very fast towards the capsule and found it at 6:36 a.m. They said Yang felt good and the conditions with the capsule also seemed normal.

  At 6:51, Yang Liwei went out of the capsule on himself, waving and smiling to rescuers and reporters.

  Li Jinai, director of Chinas space program, said that, the actual (实际) landing site is only 4.8 kilometers from the designed site (预定着落点), the conditions of the return capsule are good and Yang could walk out of the capsule on himself. All these marked the complete success of the manned flight.


  1. When Yang Liwei stepped out of the capsule, he looked____ .

  A. tiredB. afraidC. all rightD. sad

  2. The capsule landed____ .

  A. far away from what it was designed

  B. exactly on the place where it was designed

  C. not far from the place where it was designed

  D. away from Gobi Desert

  3. The passage is mainly about____ .

  A. the successful return of Shenzhou 5

  B. the successful travel around the earth

  C. the rescuing of the Shenzhou 5

  D. the designed place where the capsule should land

  Passage B


  What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter (木匠). You will probably agree too, that knowing how to investigate (调查), how to gather information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be made certain by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.

  The scientists knowledge must be exact. There is no room for halfright or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times.① If the conditions are different, any changes the scientist sees and notices in an act of proving must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the theory of relativity,② arrived at this theory through mathematics or maths. The accuracy (正确性) of his mathematics was later tested through investigations. Einstein's ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations (计算) that may test his investigations.


  1. What makes a scientist according to the passage?

  A. The tools he uses. B. His ways of learning.

  C. The ways he uses his tools. D. The power he uses.

  2. A reasonable scientific theory should be one that____ .

  A. works under one set of conditions at one time and also works under the same conditions at other times

  B. leaves no room for improvement

  C. does not allow any change even under different conditions

  D. can be used for many purposes

  3. What is the main idea of the passage?

  A. Scientists are different from ordinary people.

  B. The theory of relativity.

  C. Exactness is the most important part of science.

  D. Exactness and ways of using tools are the keys to the making of a scientist.


  ①What works under one set of conditions at one time must work under the same conditions at other times.其理论在某一时期某些条件下行

  Passage C


  In 1901 a German scientist named William Roentgen received the first Nobel Prize for Physics. He had discovered Xrays. He made his discovery when he noticed that in certain experiments a special kind of light was made by the cathode rays (阴极射线) hitting a screen. The other scientists working with him had noticed this light but they did not think it was important. Roentgen was the first person to ask himself questions about this special kind of light. When he examined it, he discovered a new kind of radiation called Xrays.

  We often think that a creative idea suddenly comes into our heads from nowhere.① This is not usually the case — it comes because we are ready to receive it. When someone asked Issac Newton how he had discovered the laws of gravity (引力), he replied, “I am certain that any mind working on a problem continuously will be prepared for the sudden answer.” Albert Einstein received the Nobel Prize for Physics in 1921 and said that there are discoveries waiting to be made if people continue to look and study all the time.

  One of the problems facing creative people is that their ideas may be too new for the rest of the world. It often happens that people laugh at the work of artists and scientists. Barbara McClintock is a good example of someone who continued to think she was right although for 30 years other scientists thought that she was wrong. Finally, her work proving that genes (基因) can make sudden changes in heredity (遗传) won her the Nobel Prize in 1983.②

  Many creative people looking for ideas or solutions find them in a visual (幻觉) form first. Elias Howe, the man who invented the sewing machine, had a big problem facing him. He could not understand how to connect the needle to the rest of the machine. Needles had always had a pointed end, with the hole at the other end. One night in a dream he was “attacked” by people with sharp spears (矛). In the morning he said, “There is the answer staring me in the face!”③ He made a hole in the sharp end of the needle and then connected it to the sewing machine.


  1. We can infer (推断) from the passage that “creativity” means ____.

  A. the imagination to find a way of doing things

  B. the plan to make an important discovery

  C. the ability to make something different

  D. the power to make something new

  2. The writers purpose in writing this passage is____ .

  A. to tell some interesting stories

  B. to prove that people are creative in many ways

  C. to praise some great scientists

  D. to explain why some people are clever

  3. Which of the following statements is best supported by the third paragraph?

  A. Believe in your own ideas.

  B. Pay attention to your dreams.

  C. Ask questions about everything around you.

  D. Collect as much information as you can.

  4. Which of the following statements is FALSE ?

  A. You can be more creative if you read a lot.

  B. You can improve your creativity by asking lots of questions.

  C. You can help your creativity by getting into the habit of thinking about ordinary things.

  D. Doing a lot of preparation can help you be more creative.
