五、阅读理解
The journey to the moon has been the first step towards future exploration（探险)space. The distance between the moon and the earth is very short indeed when compared the distances between earth and the other planets. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next aim. Such travels will be more challenging(挑战) than the trip to the moon and certainly more adventurous(冒险).
Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed（确认）nor ruled out. Russians have discovered that the surface of Venus(金星) is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠) and the pressure is nearly a hundred times greater than that of the earth's atmosphere.
Scientists believe man may find planets, which have the same conditions as those we have on earth, but man should realize the earth will be his only home for a long time and begin to love and care for it.
( )1. According to the passage, traveling to the planets will be_________
A. much easier and even more interesting B. far more exciting and dangerous
C. man's final aim D. man's first step

A. Mars is nearer to the earth than the moon.
B. The moon is much nearer to the earth than Mars.
C. Of all the planets, Mars is the nearest to the earth.
D. All the planets are much farther to the earth.
( )3. From the passage, we can guess__________
A. there is life on Mars
B. there is no life on Mars
C. the atmosphere of Mars is not so dense as that of Venus
D. Scientists will have little hope to find the answers
( )4. Man can live on under the conditions of_____________
A. much too hot surface B. the same pressure as we get on the earth
C. normal atmosphere as we have on the earth D. both B and C
( )5. Scientists think we should take care of our earth because____________
A. no other planets are going to take the place of the earth
