Another journey of challenge and danger was about to begin. The first days the weather was very good. The wind was icy but not very strong and there w

22、ed (解冻) a frozen cake over my fire, placed a candle on the top, lit it and sang “happy birthday to me” at the top of my voice. A few days later, I was moving forward over a slope that seemed safe when suddenly without warning my world dropped out from under my skis. I had fallen into a hole and was

23、hanging on the ropes tied to the sled. A piece of ice fell down and I never heard it land. The bottom was a few hundred feet below. I used to practise self rescue many times in the mountains where I lived and carefully began climbing out. It took me a long time but I finally got out. I was thankful

24、for all training I had had. I was in good health and all of my equipment was working well. I was so happy that I decided that the next day, the 22nd day of the expedition, I would increase my workday to 12 hours. The next morning I had a bad accident with the sled and hurt my leg. I couldnt stand on

25、 my left leg and my head was woozy (眩晕的) from hitting the ground. But I knew that I had to get up. Lying on the ice, I would soon die.

26、lay down out of the cold wind. I had to make a decision. Wait to get better or give up? I had to think of my family, which is very important to me, and do the right thing. I did so without regret.

31、als? Yes, we may only do a little bit, but together our small actions add up to a lot. 1. Protect wildlife habitat Perhaps the greatest threat that many species are facing is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat.

32、 In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the habitats that are left untouched by habitat destruction. 2. Reduce

33、the threat of invasive(入侵的)species The spread of nonnative species has greatly reduced native populations around the world.

36、d keep an eye out for wildlife.1. What would be the best title for this passage?A. How Animals Go to ExtinctionB. The Importance of Protecting WildlifeC. What to Do to Help Save WildlifeD.

38、 habitats of many species have been destroyedB. about one billion birds are attacked by invasive species each yearC. perhaps the biggest threat to many species is that they are easily bumped by carsD. invasive species only compete for food with native species答案与解析1C主旨大意题。本文主要列举了人们该怎样伸出援手去救助濒危动物，故C项最能概括文章的大意，为最佳题目。2D细节理解题。根据第三种措施的描述可知，在窗户上贴花纸是为了避免飞鸟因误撞而丧命。3C短语意思猜测题。根据上文的意思：入侵物种与当地的物种争夺资源和栖息地。再结合该句的意思“它们甚至直接prey on当地的物种，这样迫使当地的物种灭绝”可推知，该短语的意思为“猎食，捕食”。4A细节理解题。每年大概有十亿只鸟是死于误撞窗户，而不是外来物种的袭击，故B项错误；很多物种的最大威胁应是栖息地被破坏，故C项不对；入侵物种和本地物种竞争的不仅仅是食物，还有栖息地和资源，故D项错误。因此选A项。
