听力原文： Teams of teachers and school administrators from at least fourteen American cities are at a conference in Washington. The American Federation of Teachers, a labor union, holds the Quest conference every two years.
This year, one of the subjects is a tutoring program that provides extra help to students in Rochester, New York. The Rochester City School District was one of five in the nation recognized by the Bush administration for their tutoring programs. Tutoring is big business in the United States these days. There are private learning centers where parents can take their children after school. Test preparation companies are also doing well. One reason for all this tutoring is the growing competition for places at top universities. Another influence is the Bush administration’s federal education law, called No Child Left Behind. The law requires services like free tutoring for poor students at schools that fail to meet educational goals for three years. There is federal money to pay the tutors. But the No Child Left Behind law does not say who must do the tutoring. It can be a private company or local teachers. The law does say, however, that the provider must have shown a record of effectiveness in helping students learn. In Rochester, the tutoring is provided by a teachers union, the Rochester Teachers’ Association. The program began in the spring of 2003 with 47 students and 15 tutors.

听力原文： Among global warming's most frightening threats is the prediction that the polar ice-caps will melt, raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded.
Scientists agree that key player in this scenario is the West Antarctic ice sheet, a Brazil-size mass of frozen water that is as much as 7, 000 feet thick. Unlike floating ice shelves which have little impact on sea level when they break up, the ice sheet is anchored to bedrock well blow the sea surface. Surrounded by open ocean, it is also vulnerable, but Antarctic experts disagree strongly on just how unstable it is.
Now, new evidence reveals that all or most of the west Antarctic ice sheet collapsed at least once during the past 1. 3 million years, a period when global temperatures probably were not significantly higher than they are today. And the ice sheet was assumed to have been stable. In geological time, a million years is recent history. The proof, which was published last week in Science, comes from a team of scientists from Uppsala University in Sweden and the California Institute of Technology who drilled deep holes near the edge of the ice sheet. Within samples collected from the solid substance lying beneath the ice,they found fossils of microscopic marine plants which suggest that the region was once an open ocean, not solid ice. As Herman Englehart, a co-author from the California Institute of Technology says, "the West Antarctic ice sheet disappeared once, and can disappear again. "
26. Q: What is one of the most frightening threats of global warming according to the passage？
27. Q:What did scientists disagree on？
28. Q:What does the latest information reveal about the West Antarctic ice sheet？
29. Q:What does the scientists' latest finding suggest？

A．The whole Antarctic region will be submerged.
B．Some polar animals will soon become extinct.
C．Many coastal cities will be covered with water.
D．The earth will experience extreme weathers.
Oil tankers, for instance, have been allowed to get bigger and bigger without sufficient thought being given to emergency braking and maneuvering arrangement. Collisions at Sea continue, but little effect has been made to develop safety devices as effective as those used for aircraft.
Scientists were outspoken in expressing their concern during a recent meeting of the British Association. Unanimous approval was voiced when the leading speaker urged that a permanent national rescue services should be established, equipped for any emergency and ready to move off immediately.
of all the possible disasters mentioned, the one promoting most discussion was a major release of radioactivity from a nuclear power station. one does not need a particularly vivid imagination to visualize the other possibilities discussed. What would be the effect of a jumbo-jet crashing on a large chemical plant handling destroying liquids？ Could the tapping of natural gas lead to any form. to collapse？ Suppose a lorry full of a highly poisonous chemical crashed unseen into a large reservoir？ Dams can burst, abnormal conditions can lead to massive electrical blackouts.
An intensive study of such possibilities could at least reduce the effects of future disasters. For example, it would mean that a number of technical alternatives (such as the choice between detergent or chalk for dispersing oil) could be examined and tested in advance so that specially trained expert would know exactly what action was needed in a given emergency.
The main idea of the second paragraph is that ______
A．safety precautions in aircraft are not as effective as those used on ships
B．modern oil tankers can stop or turn easily in spite of their size
C．there are now fewer collisions at sea because of modem safety devices
D．oil tankers are so big that special devices are needed
A．At a railway station.
B．At a bus center.
C．In the countryside.
D．In a coastal town.
A.3,200
B.3300
C.3400
D.3500
A.prevent
B.anticipate
C.discourage
D.prompt
Coastal regions are mentioned as cases where _________.
A．sea water is less salty because fresh water joins in
B．rivers carry industrial exhaust into sea
C．sea ice tend to melt more quickly than in the center of oceans
D．heavy water sinks to the deeper portions of the oceans
Is there enough oil beneath the Arctic National Wildlife Refuge (保护区) (ANWR) to help secure America's energy future？ President Bush certainly thinks so. He has argued that tapping ANWR's oil would help ease California's electricity crisis and provide a major boost to the country'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 to 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 (开采权使用权费) and leasing fees for Alaska and the Federal Government. Best of all, advocates of drilling say, damage to the environment would be insignificant. "We've never had a documented case of an 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'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's impact on the California power crisis, environmentalists point out that oil is responsible for only 1% of the Golden State's electricity output--and just 3 % of the nation's.
What does President Bush think of tapping oil in ANWR？
A．It will increase America's energy consumption.
B．It will exhaust the nation's oil reserves.
C．It will help reduce the nation's oil imports.
D．It will help secure the future of ANWR.
