Do you suppose Darwin, one of the greatest scientists of all times, really

did fools' experiments?  

       Or did he do experiments that were so simple and basic that other people just thought they were foolish?

Sometimes people think they already know the answer to a question or the solution (解决办法) to a problem. Sometimes they really do know an answer or a solution, but without thinking they are important.

       Charles Darwin didn’t settle for (满足于) just thinking he knew something. And, he believed all things could be important however simple they seemed to be.

Suppose you drop two sheets of paper which are exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheet. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything.

But this simple experiment is important. It explains part of our present-day understanding of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.

     Science sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, what we might think is foolish, can shake the foundations (基础) of science.

68. “Sometimes people think they already know the answer to a question.” This means that _________.

   A. they are already told the answer

   B. the question is so important that everyone should know the answer

   C. they are already to answer such a question by others

   D. the question is simple enough for them to answer

69. From the passage, we learn that Charles Darwin _________.

A. did many fools' experiments

   B. enjoyed doing simple experiments

   C. was not satisfied with what he knew

   D. tried to prove that Galileo and Newton were sometimes wrong

70. The underlined phrase “set aside” most probably means “________”

  A. throw away        B. store up     B. put to use       D. realize

71. The author of the passage tries to ________.

A. convince(使…信服) us that Charles Darwin, Galileo and  Newton are the greatest scientists in the world

 B. draw the conclusion that basic sciences are simple things

C. prove that two sheets of paper, with the same size and shape, will fall at the same speed

 D. draw our attention to everyday happenings around us

       Unusual incidents are being reported across the Arcitc. Inuit(因纽特人)families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud .There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach of hunters. Climate change may still be a rather abstract idea to most of us ,but in the Arctic it is already having great effects –if summertime ice continues to shrink at its present rate ,the Arctic Ocean could soon become almost ice-free in summer .The knock –on effects are likely to include more warming, cloudier skies ,and higher sea levels .Scientists are increasingly eager to find out what’s going on in the Arctic.

       For the Inuit the probkm is mgent. They live in unsteady baiance with one of the toughest environments on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the Arctic as well as the locals, which is why they are not content simply to stand back and let outsider experts tell them what’s happening. In Canada, where the Inuit people are trying hard to guard their hard-won autonomy in the country’s newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral knowledge with the best of modern science. This is challenge in itself.

       The Canadian Arctic is a vast , treeless polar desert that’s covered with snow for most of the year. Adventure into this area and you get some idea of the hardships facing anyone who calls this home. Farming is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea fist. The environment tested them to the limits: sometimes the settlers were successful, sometimes they failed and disappeared. But around a thousand years ago, one group appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today’s Inuit people.

67.Which of the following is not likely to be the effect of climate change?

       A.Shorter and shorter summertime.

       B.Ice-free summer around the Arctic.

       C.Higher sea levels.

       D.More dloudy skies.

68.The Inuit people believe the solution to the climate change problem is______.

       A.to change their way of life

       B.to use their ancestral knowledge

       C.to make the best of modem science

       D.to use their ancestral knowledge and modern science

69.It can be concluded from the last paragraph that______.

       A.the first settlers in the Arctic survived by taking advantage of sea fish

       B.it’s hard to farm in the Arctic due to the climate change

       C.the ancestors of Inuit people stood out among the settlers

       D.the Thule people from Alaska invented iron tools

70.Which of the following is the best title of this passage?

       A.Climate change and the Inuit

       B.Climate change around the Arctic

       C.Global warming around the world

       D.The Inuit and their ancestors around the world
