Question

C

     A planet called Kepler 22b was discovered!It is supposed to be an ideal home for future human. It has both land and water and has temperatures which average around 72 degrees. It also has the right atmosphere to support life. But it is 600 light years from the Earth.

     The planet,where a year lasts 290 days,was first discovered two years ago. NASA scientists watched it with the Kepler space telescope for many years. The result offers the best hope for future human to live on the planet,although it is outside the Solar System.

     One of the key conditions for human to live on a planet is temperature. And the right distance from the main star can offer the temperature which is neither too cold nor too hot. “We have already come to a conclusion,it is true that Kepler 22b is a living place for mankind!” Bill Borucki,a researcher from NASA Ames Research Center,said like this.

     There are another two planets outside the system. In May,French astronomers identified Gliese 581d. In August,a team from Switzerland discovered another planet called HD 85512b. HD 85512b is 3. 6  times as large as the Earth while Gliese 58Id is about six times as large as the Earth. And the two planets are much closer to our earth than 22b. The closer one to us is Gliese 581 d,which is around 20 light years away.

() 1. People can live on the planet 22b because it has .

   A. land and water

   B. land and temperatures

   C. land,water and temperatures

   D. land,water,temperatures and the right atmosphere

() 2. On the planet 22b people will have days in a year.

   A. 600   B. 365

   C. 360   D. 290

() 3. The underlined word “identified” here means “ ” in English

   A. discovered   B. observed

   C. boarded   D. closed

() 4. Which of the planets is the closest to the Earth?

   A. 22b. B. Gliese 581 d.

   C. HD 85512b. D. None.

() 5. Which of the following is NOT true according to the passage?

   A. The planet 22b is outside the Solar System.

   B. Both HD 85512b and Gliese 58Id are smaller than Earth.

   C. The planet HD 85512b was discovered by Swiss scientists.

   D. On the planet 22b,the temperature is neither too cold nor too hot.

Answer 1

C 阅读提示：一颗叫Kepler 22b的行星被人们发现，这里是未来人类的理想居住地。这里有适合人类生存的陆地、水、气温和适当的大气层。

1. D细节理解题。由第一段可知，人们可居住在叫作Kepler 22b的行星上，因为上面有适合人类生存的陆地、水、气温和适当的大气层。

2. D 细节理解题。由第二段的“The planet,where a year lasts 290 days,was first discovered two years ago. ”可知，在 Kepler 2b 行星上，一年只有290天。

3. A 词义猜测题。由下文中的 “ In August,a team from Switzer land discovered another planet called HD 85512b. ”可知，identify 和discover为同义词，意为“发现”。

4. B细节理解题。由最后一段最后一句“The closer one to us is Gliese 581d,which is around 20 light years away. ” 可知，Gliese 581d离地球最近。

5. B 细节理解题。由最后一段的“HD 85512b is   3. 6 times as large as the Earth while Gliese 58Id is about six times as large as the Earth. ”可知，HD 85512b和Gliese 581d两者都比地球大。
