[单项选择]An image taken of the Pacific Ocean last September is astonishing. Made using data collected from satellites monitored by NASA’s Jet Propulsion Laboratory in Pasadena, California, the picture shows the surface level of the Pacific as clearly as a yardstick lying across a lumpy bed. One sample of water--with a volume 30 times that of all the Great Lakes--is white, indicating that it is as much as 13 inches higher than its normal level.
El Nino experts are still striving to tackle the really big question: what is causing the abnormal El Nino behavior of the past two decades Some said because global warming accelerates the pace of E1 Nino formation and reinforces each event. Supporters of global warming as El Nino instigator include Kevin Trenberth, a climate analyst with the National Center for Atmospheric Research in Boulder, Colorado. "There’s evidence that global warming didn’t have much impact until 1979, but now it’s beginning to break through," he says.

A. lack of detailed accounts
B. its inconsistent behavior
C. the need for advanced technology
D. its increasing frequencies

[判断题]From last Valentine’s Day on, Lori Lee’s image had never left my mind.

[单项选择]The Indian ’Ocean is the third largest ocean in the world. Only the Pacific and the Atlantic are larger. More than one-fifth of all the world’s water supply is in the Indian Ocean.
The Indian Ocean touches four different continents. To the south is Antarctica and to the east is Australia. Africa lies to the west and Asia lies to the north. There are several important islands in the Indian Ocean. These include Madagascar, the largest one, which is near Africa, and Sri Lanka, which is near India. There is also a group of islands called the Seychelies near the African coast.
The Indian Ocean is extremely important to the countries in southeast Asia. Strong winds from the Indian Ocean bring warm weather, and heavy rains are necessary for growing food.
We may conclude that ______ .
A. India is larger than Antarctica
B. The Indian Ocean is to the east of Australia
C. Madagascar is larger than Sri Lanka
D. The India Ocean is larger than the Atlantic

[单项选择]Most of Earth’s surface is ocean. The ocean floor is inaccessible for extensive research without equipment of greater technological sophistication than is currently available. It must therefore be true that scientists know less about the ocean floor environment than about almost any other environment on Earth.
Which of the following, if true, provides the most support for the conclusion
A. Many mountain ranges lie entirely beneath the ocean surface, yet new underwater surveying equipment has produced three-dimensional charts of them that are as accurate as those available for mountain ranges on land.
B. Strong water currents circulate on the ocean floor, but the general pattern of their movement is not so well understood as is the pattern of air currents that circulate over land.
C. In contrast to most land environments, temperature conditions at the ocean floor are generally stable and uniform, since sunlight does not penetrate far below the ocean surface.
D. Very few people have seen detailed maps of extended regions of the ocean floor, even though such maps are available in almost all large libraries.
E. (E) Animals living on the ocean floor must be able to withstand water pressure that is far greater than the atmospheric pressure with which land animals live.
