九年级英语单项填空中等难度题查看答案及解析

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.

Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.

But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.

1.For a long time humans think ________.

A. they can surely find life on Mars

B. there may be life on Mars

C. it’s too late for them to explore Mars now

D. Mars is the only planet that has life on it

2.The two robots ________.

A. have found out that it is warm and wet on Mars

B. were sent to Mars to find some stones

C. were the first two American robots that landed on Mars

D. are the only machines that have landed on Mars so far

3.The third paragraph mainly tell us ________.
