We are warned by our teachers not to waste time because time 26 will never return. I think it quite 27. What does time look 28 ? Nobody knows, and we can’t see it or touch it and no 29 of money can buy it. Time is abstract(抽象的), so we have to  30 about it.

Time passes very quickly. Some students say they don’t have 31 time to review their lessons. It is 32 they don’t know how to make use of their time. They waste it in going to theatres or playing, and 33 other useless things. Why do we study everyday? Why do we work? Why do most people 34 take buses instead of walking? The answer is very 35 .We wish to save time because time is36.

Today we are living in the 21^st century. We 37  time as life. When a person dies, his life ends. Since life is short, we must 38 our time and energy to our study so that we 39 be able to work and live well in the future. Laziness is the 40 of time, for it not only brings us 41 , but also does other 42 to us. If it is necessary for us to do our work today, 43 we do it today and not 44 it until tomorrow. Remember that time is much more 45.

Unusual incidents are being reported across the Arctic. Inuit（因紐特人）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（抽象的）idea to most of us, but in the Arctic it is already having great effect—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（連鎖反應(yīng)）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 problem is urgent. They live in unsteady balance 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（自治權(quán)）in the country’s newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral (祖先的) knowledge with the best of modern science. This is a 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 first. 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.

Which of the following is likely to be the effect of climate change?

  A. Shorter and shorter summertime.     B. Ice-free summer around the Arctic.

The Inuit people believe the solution to the climate change problem is ________.

  A. to change their way of life

  B. to do as their ancestors

It can be concluded from the last paragraph that ________.

  A. the first settlers in the Arctic survived there quite easily

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

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

  D. the Thule people from Alaska invented iron tools

Which of the following is the best title for this text?

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
