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 willbe 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 V enus(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. ( )41. According to the passage, traveling to the planets will be_________A. much easier and even more interestingB. far more exciting and dangerousC. man's final aimD. man's first step ( )42. Which of the following is NOT true?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.( )43. From the passage, we can guess__________A. there is life on MarsB. there is no life on MarsC. the atmosphere of Mars is not so dense as that of VenusD. Scientists will have little hope to find the answers( )44. Man can live on under the conditions of_____________A. much too hot surfaceB. the same pressure as we get on the earthC. normal atmosphere as we have on the earthD. both B and C( )45. Scientists think we should take care of our earth because____________ When read it, underline the useful sentences.Do them alone.Then discuss in groups.Check the answers in class.A. no other planets are going to take the place of the earthB. everything needed is provided by the earthC. the only home of man will be the earth for a long timeD. the dream to find another home for man will come true VI、句子翻译46．没有水、氧气和食物，人类无法生存。
