  The plan: turn Mars into a blue world with streams and green fields, and then

题型:不详难度:来源:

  The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.
  This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
  But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.
  But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said, “This is just wrong.”
5. The passage is about________.
A. a plan turning Mars into a little earth
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
6. Which of the following is NOT the reason why some scientists are against the plan?
A. The project would wipe out all the native lifeforms on the Mars.
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed. 
7. We can infer from the passage that________.
A. water is a crucial factor for life
B. the project will have little effect on the native lifeforms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
8. Which of the following supports the conclusion of microbes living in the Mars’s soil?
A. Scientists found liquid water in the Mars.
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.
答案

5---8    ABAB  
解析
本文是议论文,描绘了把红色火星改造成蓝色的“生命天堂”的宏伟规划,综述了科学家对这个火星改造工程所持的不同观点。
5.A   主旨大意题。根据第一段第一句The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures  from the earth.可知这段短文主要讲的是火星改造计划的设想。
6.B  细节题。根据短文所述,科学家反对这个设想的理由有:“We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet”, 和that would destroy all these native lifeforms。B项没有提到。
7.A  推测题。根据scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet的内容,我们知道科学家越来越相信火星上存在生命,因为有证据表明火星土壤中存在大量的水,故可断定水是生命存在的关键要素。
8.B 推理题。根据The gas(methane) is a waste product of living creatures and could be produced by microbes  living in the red planet’s soil可知,火星大气层中存在甲烷的迹象,而甲烷是活着的动物产生的废物,据此科学家推断这可能是生活在火星上的微生物产生的。故可得出结论:火星上可能存在微生物,主要证据是火星在大气层中发现了甲烷的迹象。

Who has deprived the children"s happiness of learning???  
Children are born with a natural desire of learning. They are curios and concerned about   36  around them. They are   37  to learn anything that amazes them. They have so many   38   that they keep on asking. They can bore the   39  all day long with many   40  questions which they will never feel bored with. Why? This is because learning is their   41   , perhaps an instinct of human beings. They just can"t help. But   42   , they feel bored with learning, especially when learning becomes a boring   43   for them, especially after school has become a    44  of their life, especially when they have to   45   teachers who tell them again and again to   46    to recite and memorize things they don"t want to learn, and especially  47    they realize school is not what they once    48   to be but something that, according to their parents, they must rely on in order to   49  a good fame or a good job or a good future.

Therefore, my   54  to the students’ learning is that they   55   enjoy learning, enjoy the pleasure that they could feel from learning itself. Find back the long lost desire and curiosity of learning in their childhood.

I wanted to do something very ___37___ for my fifteen-year-old son, who has always been the perfect child. He ___38___ all summer to earn enough money to buy a used motorcycle. Then, he spent hours and hours on it ___39___ it looked almost new. I was so ___40___ of him that I bought him the shiniest helmet and a riding outfit.
I could ___41___ wait for him to open up his gift. In fact, I barely slept the night before. Upon a wakening, I went to the kitchen to ___42___ the coffee, tea, and morning goodies. In the living room was a beautiful keyboard with a ___43___:” To my wonderful mother, all my love, your son.”
I was so ___44___. It had been a long-standing joke in our family that I wanted a piano so that I could ___45___ lessons. “Learn to play the piano, and I’ll get you one” was my husband’s ___46___.
I stood there shocked, crying a river, asking myself how my son could ___47___ this expensive gift.
Of course, the ___48___ awoke, and my son was thrilled(激动的)with my reaction. Many kisses were ___49___, and I immediately wanted him to ___50___ my gift.
As he saw the helmet and outfit, the look on his face was not ___51___ what I was expecting. Then I ___52___ that he has sold the motorcycle to get me the keyboard.
Of course I was the proudest mother ___53___ on that day, and my feet never hit the ground for a month.
So I wanted you to know, that kind of love still ___54___ and lives even in the ever-changing world of me, me, me!
I thought you’d love to ___55___ this story.
Yours,
Hilary
