题目内容

Alaska is known for its cold and snowy weather. For many years, dog sleds (雪撬) were the only means (方式) of transportation during the long winter. Today, some Alaskans combine fun and hard work in a yearly dog sled race. The Iditarod Trail Race is the longest dog sled race in the world. It lasts from two to three weeks and covers almost seventeen hundred kilometers.

The race goes across Alaska from Anchorage to Nome. It follows trails that were once used by people who looked for gold in Alaska's wilderness. The race also follows the route of several brave Alaskans who brought medicine from Anchorage to Nome in the winter of 1925. They carried the badly needed medicine through bad storms and helped save many lives.

The race, which is held in March, is very hard for the dog sled drivers. Each day, the dogs run for about four hours and then rest for four hours. They run day and night and sometimes travel as much as 110 kilometers a day. The drivers must feed and take care of the dogs during the rest periods. Sometimes they only sleep for about two hours each day. Because the race is so hard, many drivers don't expect to win. For most of them, just being able to finish is a victory.

Shishmaref, an Eskimo village on an island off northwestern Alaska, is falling into the ocean. Giant storm waves have so hit the place—once well buffered by sea ice—that villagers voted in 2002 to leave their ancestral home for the mainland. They are being called one of the first refugees（难民）of global warming. k+s-5#u

“We tend to describe climate change in terms that are abstract—a one degree rise in temperature, an increase in greenhouse gases—but when waves wash away a village, that’s concrete and very emotional,” says Igor Krupnik, an expert at the National Museum of Natural History. “When they lose a piece of their land, they aren’t just losing a certain number of square miles. They are losing part of their history and their memory. They are losing childhood events and grandparents’ tales.”

Before temperatures began to rise in Shishmaref about 30 years ago, 20 to 30 miles of hard sea ice protected the village from powerful fall storms. But the natives say the ice doesn’t freeze as solidly or as soon as it used to and now stretches only six or seven miles, leaving the community of 600 people more exposed. Storms have swept houses into the ocean.

The villagers’ plan is to move to Tin Creek, a site on the Alaska mainland 12 miles away, and they have received $180 million from the government. Residents hope that in their new community they’ll be able to maintain their close ties, continue hunting animals, and keep fishing, much as their ancestors have done for centuries. “People are asking why the government should be spending so much money on so few people,” said a government official. “But people in Alaska are like everyone else. We want to help keep their culture alive.”

The underlined word “buffered” probably means “______”. k+s-5#u

A．protected B．destroyed C．prevented D．damaged

According to the passage, _____ caused the village to be in danger of disappearing.

Even if you are an experienced backpacker or climber，you need to know what to do if something goes wrong．It is not that Alaska is that much more dangerous than other places．It is no more hazardous than elsewhere，as long as the proper precautions(预防措施)are taken．So, being prepared is crucial to ensure a safe trip．
First of all，make sure you pack everything you will need for your trip．Even if you are traveling by car，pack clothes and gear for backpacking．Because of the bad weather, cars break down frequently. Pack a survival(生存)kit full with：a down coat, boots ,mittens, a hat, snow-pants，sleeping bags，candles，a flashlight，and high-energy food. If you are traveling by car , also pack extra belts, a shovel, and a chain.
If you are camping or hiking，make sure you know how to avoid bears．If you are lost in the wilderness, there is no doubt you will encounter them.
However，there is no need to be nervous．Just take these precautions：make noise as you walk，bears will avoid you；cook your food away from where you sleep，and store your food away from where you sleep，so the bears are not attracted．Both of these should keep the bear away．However，if you do encounter a bear，there are two different schools of thought．One is to make noise and scare the bear away．The other is to stand still and speak softly to get the bear to leave．If you are dealing with a brown bear，you can climb a tree，since it cannot follow．But，black bears can climb．If for some reason the bear attacks，play dead．Try to protect your head and neck，and hopefully the bear will leave its“dead” prey.
