But what should I do to celebrate my 60th birthday? What else, but a journey
19、 at the opposite end of the world, Antarctica. I began my almost 400 mile journey on November 1st, 1997. I walked and skied alone. My dog team were not with me to pull my sled (雪橇). Another journey of challenge and danger was about to begin. The first days the weather was very good. The wind was icy
20、 but not very strong and there was bright sunshine 24 hours a day. But changes were just around the corner. On the third day I was struggling through stormy weather and during the next week the wind grew stronger and I found myself spending a whole day in my tent. I had traveled only two hours one d
21、ay when the wind increased so much that I had to put my tent up before the wind became too strong. Within a few minutes the wind increased to a howling storm that threatened to blow me and my tent away, but none of that happened. On November 12th the storm died down. It was my birthday and I wanted
22、to make that day special. I thawed (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
23、 had fallen into a hole and was 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
24、finally got out. I was thankful 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
25、 hurt my leg. I couldnt stand on 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. I struggled to my knees knowing that somehow I had to put my tent up for shelter. On hands and knees I got the tent up and dragged my
26、 sleeping bag into the tent and 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. I had met the challenges of solo (独自的) travel in an extreme climate. It
27、 is an experience I shall never forget and shall value for the rest of my life.1The sun does not go down in Antarctica, so the writers workdays were usually_A. 12 hours B. more than 12 hoursC. less than 12 hours D. 24 hours2The writer was born on_A. 1 November, 1937 B. 12 November, 1937C. 22 Novembe

29、did the writer make after the accident?A. She spent a whole day in her tent.B. She waited till she got better and continued her journey.C. She gave up and went back home.D. She was thankful for all training she had had.答案与解析1C根据文章中的“I would increase my workday to 12 hours.”可知，她打算将每天的工作时间增加到12个小时。因此，
30、此前她每天的工作时间肯定少于12个小时。2B根据文章中的“On November 12th the storm died down.It was my birthday and I wanted to make that day special.”可知她的出生日期。再根据第一段中提到的当时是1997年，她60岁，这样可以计算出她的出生时间是1937年11月12日。3D根据文章第七段中的“The next morning I had a bad accident with the sled and hurt my leg.”可知事故发生的原因。4C由文章最后一段可推知。C Can we give
31、 a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot. 1.

32、ult in loss of wildlife habitat. 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
33、 habitat destruction. 2. Reduce the threat of invasive(入侵的)species The spread of nonnative species has greatly reduced native populations around the world.

34、es towards extinction.3. Place decals on windowsIt is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office. 4. Slow down when
35、 driving Many native animals have to live in developed areas and this means they must move in humanliving areas. One of the biggest obstacles(障碍) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when y
36、oure out and about, slow down and 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.

38、arn from the passage that_A. the 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。
