1 . Five meteorologists (气象学家) who were trapped for two weeks after polar bears surrounded their weather station are now able to leave after the creatures were chased away. Their supervisor told NBC News early Wednesday.

Russian officials had feared the siege could last for another month, the time it would take to reach the islands in the Kara Sea, high in the Arctic Circle. But on Tuesday night a research ship took a detour (绕道) to assist those weathermen, station supervisor Vasily Shevchenko told NBC News. The ship run by Russia’s state-run oil firm Rosneft frightened away the bears using its helicopter, before resupplying the weather station with more food and puppies (幼犬). The puppies are not yet big enough to deter the bears, but the station is planning to draft in a replacement adult guard dog as soon as possible.

Some of the bears had taken to sleeping directly outside the windows of remote outpost. There was no risk of the researchers starving because they had a year’s worth of food, but they were forced to take dangerous trips to a nearby building, holding a gun for protection, according to Shevchenko.

Polar bears are an endangered species. In Russia, it’s a crime to shoot them unless in self-defense. The bears usually leave the islands in the summer, but this time they were trapped by the melting ice, an apparent sign of climate change, according to Shevchenko. “They’ve stayed on the island because there is nowhere for them to go,” he said.

The animals suffer from global warming because it shrinks the floating ice that forms their main hunting ground. According to the environmental group the World Wide Fund for Nature, known as the WWF, this has got some polar bears to go near human habitats in search of food.

2 . It’s always been a rule in my family, spoken or unspoken, that you don’t waste food. With six children herself and having grown up in an even larger family through the Great Depression, my mother would never tolerate throwing out the amounts of food we see routinely these days in the dumpster. We were told simply to clean our plates, no matter whether we liked the taste or if we were not hungry or not. So this subject is deep in my genes and upbringing.

Estimates are that nearly one third of all food produced is wasted. USDA estimates 31% of food available at retail (零售)level is wasted. 12% of landfill material is food. 28% of agricultural land produces food which is wasted, says the FAO. 18% of vegetables, and 12% of the apple crop are lost at the farm level in the United States., say experts.

Luckily, there’s an “ugly food” movement picking up steam. “Ugly” foods are those that sellers and buyers often reject because of their appearance, like misshapen vegetables and bruised（擦伤的） fruits. Farmers dump them. Supermarkets and restaurants reject them. Now supermarkets and restaurants reject them. Consumers historically have avoided them. Now supermarkets feature the ugly. It’s fashionable. More artful terms are favored. A French supermarket chain is selling “inglorious” foods. The British chain ASDA uses “wonky（歪斜的）” (which to American ears might sound as bad as “ugly.”) Canada’s Loblaws uses “naturally imperfect.” Celebrity chef Jamie Oliver, who has cast himself as a promoter of the “good food movement,” has signed on with some British chains to support their efforts.

With the effort of Kretschmann Farm CSA’s we’ve taken the line that rather than throw away things which would be classified by others as ugly, inglorious, or imperfect, we would just give them to you and you could decide. Either we throw them away, or you can. Oftentimes this adds to the volume of the box, or makes it a little more urgent to consume (because sometimes those rejected foods are just very ripe!).

3 . Coffee drink is widespread. When people argue about whether coffee is good for health, they’re usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.

Traditionally, coffee bushes were planted under the shade of taller trees. However, more and more farmers in Latin America are deforesting the land to grow full sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits.

Unfortunately, deforesting for coffee production immediately decreases the local wildlife habitat, because native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there.

Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides（杀虫剂）are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, and then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.

Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade-grown" and "bird-friendly".

Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it’s worth it.

1. Which opinion does the author agree with?

A．People should buy full-sun coffee.

B．Shade-grown coffee should be supported.

C．Farmers should change the places to grow coffee.

D．Pesticides should be forbidden in coffee planting.

2. Compared with the traditional method, what advantage does the full-sun method have?

A．It can protect the ecosystem.

B．It can promote people's health.

C．It can provide mare nests for birds.

D．It can increase the production of coffee.

3. How do farmers get more land to grow full-sun coffee?

A．They cut down trees.

B．They move to other countries.

C．They turn grassland into farmland.

D．They buy more land from other farmers.

4. What can we learn from the passage?

A．It is quite worthwhile to buy shade-grown coffee at any cost.

B．Farmers all have realized the importance of protecting the environment now.

C．South American farmers are taking action to plant coffee in the traditional way.

D．The full-sun method does good to the health of human beings in the long run.

4 . What do people do with their old, out of date but still useful computers? Most people don’t know     1     to deal with them . Many old computers are put away in homes . Many more     2     (throw) away as rubbish.

Finally, some companies are thinking of ways     3     they bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell and other companies also take     4     some old computers .

In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their     5     (use) products. And 70% of the computer waste must be recycled. The idea behind the laws     6     (be) that computer companies themselves should pay for the cost. That will encourage them     7     (make) computers easier to repair and upgrade.

Yet while many people are throwing away good computers, others cannot afford     8     at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.    9     computers then go to schools, charities and people who need them. Giving a computer that you don’t use to one of the organizations can turn one person’s rubbish     10     someone else’s useful things and cut down waste, too.

7 . 语法填空

Each year     1    (thousand) of tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people traveling to the ends of the Earth can have     2    negative effect on fragile ecosystems. Should tourists     3    (allow) to visit polar regions?

About 40,000 tourists visit Antarctica each year. More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions    4    (increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other     5    (environment) damage. Because the places where wildlife is accessible     6    (be) few in number, tourist traffic can become concentrated in specific areas,     7     (put)Arctic vegetation(植被) at risk.

Others say that access     8    these very special parts of the world should not be restricted to only researchers and scientists. Polar tourism allows people to develop deep     9    （person） connections with polar regions. “Those     10    travel to the Arctic or Antarctica often become cheerleaders for supporting those places.” Jim Sano, vice president for travel and conservation at World Wildlife Fund, told TFK.
