On April 26, 2003, he found himself in a very dangerous situation when climbing in Utah. On that day, Aron’s arm 68 (catch) under a 360-kilo rock that fell on him when he was climbing by 69 (he) in the mountains. Because he could not free his arm, he stayed there for five days and hoped that someone would find him. 70 when his water ran out, he knew that he would have to die that day. So he used his knife to cut off half his right arm. Then, with his left arm, he bandaged himself so that he would not lose too much blood. After that he climbed down the mountain 71 (find) help. After losing his arm, he wrote 72 book called Between a Rock and a Hard Place. This means being in a difficult situation that you cannot seem to get out of. In this book, Aron tells of the 73 (important) of making good decisions, and of being in control of one’s life. His love for mountain climbing is so great that he kept on climbing mountains even after this experience. Do we have the same spirit as Aron? Let’s think 74 it before we find ourselves “between a rock and a hard place”, and before we have to make a decision that could mean life or death. 四、选词填空 用方框内所给单词的适当形式填空 pollution  they  expect  hungry  government  human  lead  appear  that  worry About 1, 101 manatees died in Florida last year, which was a record. Most died from 75 . So last December, government wildlife experts came up with a plan to give food to the manatees. They decided to feed 76 green vegetables like lettuce and cabbages. So far, they have served more than 193, 000 pounds of lettuce to hungry manatees. But as the weather is getting warm, the program is 77 to end soon.     Manatees are huge sea animals that only eat sea grass and other plants that live in the sea. That’s one reason why they’re sometimes called “sea cows”. Since 1967, Florida’s manatees have been on the US 78 list of endangered animals. Most dangers to manatees come from 79 . The biggest problems facing the animals are boats. Manatees are curious and rather slow. That has 80 to thousands of manatees being hit or killed by boats. At one point, there were only about 2, 000 manatees left in Florida. With protection, the number grew. In 2016, there were more than 6, 000 manatees. However, as seagrass began to 81 , the number of manatees dropped again. Warming seas with 82 water have created huge growths of algae (藻) on the ocean’s surface. The algae block (阻挡) the sunlight 83 allows the sea grass to grow. In Indian River Lagoon, where manatees often go in the winter, about 90% of the sea grass beds there have died off. Over the long term, Florida is working to help restore (恢复) sea grass beds. But that will take time. Scientists are still 84 that hundreds more manatees could die from hunger this winter. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司 $$ 人教版八年级上册Unit2小题狂练 特殊疑问句专练 一、单项选择 1．—Daming, _________ do you go to the library? —Twice a week.

So far, they have served more than 193, 000 pounds of lettuce to hungry manatees. But as the weather is getting warm, the program is 77 to end soon.     Manatees are huge sea animals that only eat sea grass and other plants that live in the sea. That’s one reason why they’re sometimes called “sea cows”. Since 1967, Florida’s manatees have been on the US 78 list of endangered animals. Most dangers to manatees come from 79 . The biggest problems facing the animals are boats. Manatees are curious and rather slow. That has 80 to thousands of manatees being hit or killed by boats.

However, as seagrass began to 81 , the number of manatees dropped again. Warming seas with 82 water have created huge growths of algae (藻) on the ocean’s surface.
