根据下面短文内容,回答题。

Different Tastes for Vacation

People like different kinds of vacations. Some go outside. Others like to stay at a hotel in an exciting city. They go shopping all day and go dancing all night. Or maybe they go sightseeing to places such as Disneyland, the Tai Mahan or the Louver.

Some people are bored with sightseeing trips. They don&39;t want to be "tourists". They want to have an adventure, to learn something and maybe help people too. How can they do this? Some travel companies and environmental groups are planning special adventures. Sometimes these trips are difficult and full of hardships, but they&39;re a lot of fun. One organization, Earth Watch, sends small groups of volunteers to different parts of the world. Some volunteers spend two weeks and study the environment. Others work with animals. Others learn about people of the past.

Would you like an adventure in the Far North? A team of volunteers is leaving from Mormons,Russia. The leader of this trip is a professor from Alaska. He&39;s worried about chemicals from factories. He and the volunteers will study this pollution in the environment. If you like exercise and cold weather, this is a good trip for you. Volunteers need ski sixteen kilometers every day.

Do you enjoy ocean animals? You can spend two to four weeks in Hawaii. There, you can teach language to dolphins. Dolphins can follow orders such as "Bring me the large ball." They also understand opposites. How much more can they understand? It will be exciting to learn about these inteIligent animals. Another study trip goes to Washington State and follows orcas. We call them "Killer Whale", but they&39;re really dolphins--the largest kind of dolphin. This &39;beautiful animal travels together in family groups. They move through the ocean with their mothers,grandmothers and great-grandmothers. Ocean pollution is chasing their lives. Earth Watch is studying how this happens.

Are you interested in h/story? Then Greece is the place for your adventure. Thirty-five hundred years ago a volcano exploded there, on Santorum. This explosion was more terrible than Karate or Mount Saint Helens. But today we know a lot about the way of life of the people from that time. There are houses, kitchens, and paintings as interesting as those in Pompeii. Today teams of volunteers are learning more about people from the past.

Do you want a very different vacation? Do you want to travel far, work hard and learn a lot?

Then an Earth Watch vacation is for you.

The Tai Mahan may be __________. 查看材料

A.a shopping center

B.a hotel

C.a dancing hall

D.a place of interest

根据下面短文内容,回答题。 Oil Exploitation Beneath ANWR&39;S Frozen EarthIs there enough

根据下面短文内容,回答题。

Oil Exploitation Beneath ANWR&39;S Frozen Earth

Is there enough oil beneath the Arctic National Wildlife Refuge (保护区 ) (ANWR) to help secure America&39;s energy future? President Bush certainly thinks so. He has argued that tapping ANWR&39;s oil would help ease California&39;s electricity crisis and provide a major boost to the country&39;s energy independence. But no one knows for sure how much crude oil lies buried beneath the frozen earth with the last government survey, conducted in 1998, projecting output anywhere from 3 billion to 16 billion barrels.

The oil industry goes with the high end of the range, which could equal as much as 10% of U.S. consumption for as long as six years. By pumping more than 1 million barrels a day from the reserve for the next two or three decades, lobbyists claim, the nation could cut back on imports equivalent to all shipments to the U.S. from Saudi Arabia. Sounds good. An oil boom would also mean a multibillion-dollar windfall (意外之财) in tax revenues, royalties (开采权使用费) and leasing fees for Alaska and the Federal Government. Best of all, advocates of drilling say, damage to the environment would be insignificant. "We&39;ve never had a document case of oil rig chasing deer out onto the pack ice." says Alaska State Representative Scott Ogan.

Not so fast, say environmentalists. Sticking to the low end of government estimates, the National Resources Defense Council says there may be no more than 3.2 billion barrels of economically recoverable oil in the coastal plain of ANWR, a drop in the bucket that would do virtually nothing to ease America&39;s energy problems. And consumers would wait up to a decade to gain any benefits, because drilling could begin only after much bargaining over leases,environmental permits and regulatory review. As for ANWR&39;s impact on the California power crisis, environmentalists point out that oil is responsible for only 1% of the Golden State&39;s electricity output and just 3% of the nation&39;s.

What does President Bush think of tapping oil in ANWR? 查看材料

A.It will exhaust the nation"s oil reserves.

B.It will help secure the future of ANWR.

C.It will help reduce the nation"s oil imports.

D.It will increase America"s energy consumption.
