2018年成人英语三级考试黄金冲刺题及答案(14) 下

 　　The top of the world is a wonderland. In winter, the temperature often falls to -30~F and the sun never rises. The ocean is surrounded by frozen ground. There are few people or trees, but to polar bears, the Arctic(北极) is home.

　　Polar bears have thick fur, big paws and other features that make them well prepared for life in their tough environment. In fact, they need the Arctic sea ice for survival. But climate change is causing larger and larger areas of summer sea ice to melt( 融化). Experts say that if warming pat-terns continue, the Arctic could be free of summer sea ice by 2050, That may cause two-thirds of the word' s 20,000 polar bears to be gone by then too.

　　Polar bears can' t survive for long on land. Seals are their main source of food. The only place where polar bears can hunt seals is on the ice. Although these bears are strong swimmers, they are no match for lightning swift seals in the water. A polar bear has brilliantly clever strategies to overcome this disadvantage. In winter the bear waits motionless beside a seal' s breathing hole, which is a narrow tunnel through the ice. Often many hours pass before the seal comes up for air and the bear kills it with a powerful blow of its paw. In summer, the polar bears that live on land eat very little and wait for the sea ice to return.

　　With the sea ice forming later in the year and melting earlier, polar bears do not have enough opportunity to hunt and eat. Less sea ice makes it harder for the bears to catch the seals. The bears must swim longer distances between ice packs( 大片浮冰), and they can' t always make it. The ice is also getting thinner. These conditions can cause polar-bear cubs to become separated from their mothers, who provide them with food.

　　Steven Amstrup is the chief scientist of Polar Bear International. The group aims to save the bears and their home. "The more people who see polar bears and understand their difficult situations, the better the chance we' 11 alter our warming path in time to save them," he says.

　　Long bus rides are like television shows. They have a beginning, a middle, and an end-with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste. "" Drink Root Beer. " "Fill up with Pacific Gas. " Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now ! "

　　The beginning of the fide is comfortable and somewhat exciting, even if you' ve gaveled that way before. Usually some things have changed--new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it' s fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the fide can be as thrilling as a suspense story.

　　Will the driver pass the truck in time? Will the driver move into the fight or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the fide. Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

　　The end of the fide is somewhat like the beginning. You know it will soon be over and there' s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you've sat with your legs crossed, with your hands in :your lap, with your hands on the armrests--even with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.

　　2.自信心的重要性;

　　3.有了正确的态度，建立信心是可能的。

　　答案：The Importance of Self-confidence

　　Self-confidence is very important to our life. As a wise man once said, "If you have no confi-dence in yourself, you are twice defeated in the race of life. With confidence, you have won even before you have started. "

　　If you are full of self-confidence, your creativeness, your enthusiasm will all be aroused, and you will overcome difficulties. As a result, your dreams will come true. On the contrary, if you have no confidence in yourself, there is little possibility that you would ever achieve anything.

　　Failure will be following you. But self-confidence comes only when you know yourself. You should know both your weaknesses and strengths. Only after this can you be well in doing great things.

　　Try something you' ve never done before. Just taking on a challenge, whether you succeed or not, can increase your confidence. In a word, self-confidence is greatly important to our success.
