题目列表(包括答案和解析)

When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.

Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.

The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.

This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

阅读短文,根据短文内容,从短文后的六个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(共8分,每小题2分)

  As you grow rapidly through your teenage years, you will experience a lot of changes. The changes may seem difficult.  1   Don’t panic! You will deal successfully with them! You are a young adult now!

  With more responsibility, you will find more freedom to make your own choices. This is a time to be well informed about making choices. In this way you can make healthy balanced decisions.  2   You may already know your career path or you may have no idea at all what you want to do. Both situations are fine! Work hard and the right opportunity will present itself to you.

  Young adulthood means greater freedom and more choices.  3   But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself.

  It is also perfectly natural at this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens.

  This period is a part of the life cycle. There are some people who will be with you throughout life’s journey. There will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not even see all of your classmates again.

  You are a young adult. It is your life. No one can live it for you.  4   So making the right choices will be important to you. Life is for living. Enjoy your life wisely.

  A. They will help shape the future.

  B. They may seem to happen quickly.

  C. You will probably want to be independent.

  D. You may appreciate what you have in your own life.

  E. The choices that you make from now on will be your choices.

  F. Your family has been with you since you came into this world.
