Although hurricane season doesn't begin until June 1, a Pacific storm has already struck. El Salvador, which was ruined by a Caribbean storm in 1995, was hit by Hurricane Adrian on Friday. This is the first Pacific-born hurricane to ever reach land in this Central American country.

Some 14,000 people left from the western coast of El Salvador. The storm weakened as it crossed land, heading east. Heavy rains created deadly flooding problems in the hurricane's wake.

Adrian is the first Pacific storm of the season. It reported maximum continuous winds of 75 miles per hour, the minimum strength of a hurricane. A Category 3 hurricane, Adrian also caused damage and flooding in Honduras. It is expected to break up before reaching the Caribbean Sea on the eastern coast of Central America.

Hurricane season typically begins June 1 and lasts through November 30．The National Oceanic and Atmospheric Administration (NOAA) has predicted seven to nine hurricanes for the 2005 season.

"It is difficult to make any kind of an exact prediction of how many of these will strike land," NOAA administrator Conrad Lautenbacher said. He predicts two to three hurricanes will strike the U.S. this season.

Last year, six of nine hurricanes reached Category 3 strength or higher. Four of those hit Florida within a six-week period. Altogether, Hurricanes Charley, Frances, Ivan, and Jeanne caused more than $40 billion in damage in the Sunshine State.

This year's forecast is based on ocean temperatures. Warmer temperatures produce more tropical storms, which can then turn into hurricanes.

"The issue, really, this year is the unusually warm sea surface temperatures in the Atlantic," said Frank Lepore of the National Hurricane Center.

60．Which of the following is the 2005 first hurricane?

A．Charley.   B．Adrian.    C．Jeanne.    D．Frances.

61．How many countries struck by the hurricane are mentioned in the text?

A．Six. B．Nine.       C．Five.       D．Three.

62．We can infer that warmer ocean temperatures ______.

A．have nothing to do with the hurricane

B．cause less hurricane

C．are more likely to cause the hurricanes

D．do a lot of damage to the areas along the coast

63．The passage implies that _______.

A．hurricane season comes early this year

B．every hurricane formed in oceans could cause great damage to the land

C．hurricane often comes in winter and spring

D．tropical storm is more severe than hurricane

 Early this year cruel snowstorms hit southern China , ______ great transportation problems in some areas .

It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans.
Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely
monitoring a deep-sea volcanic eruption （爆发） for the first time and that they plan similar studies.
Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.
The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope （听诊器） does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.
81. The passage is chiefly about ____ .
A. an effort to protect an endangered marine species
B. the civilian use of a military detection system
C. the exposure of a U.S. Navy top-secret weapon
D. a new way to look into the behavior of blue whales
82. The underwater listening system was originally designed ____ .
A. to trace and locate enemy vessels
B. to monitor deep-sea volcanic eruptions
C. to study the movement of ocean currents
D. to replace the global radio communications network
83. The deep-sea listening system makes use of ____ .
A. the sophisticated technology of focusing sounds under water
B. the capability of sound to travel at high speed
C. the unique property of layers of ocean water in transmitting sound
D. low-frequency sounds travelling across different layers of water____
84. It can be inferred from the passage that____.
A. new radio devices should be developed for tracking the endangered blue whales
B. blue whales are no longer endangered with the use of the new listening system
C. opinions differ as to whether civilian scientists should be allowed to use military technology
D. military technology has great potential in civilian use
85. Which of the following is true about the U.S. Navy underwater listening network?
A. It is now partly accessible to civilian scientists.
B. It has been replaced by a more advanced system.
C. It became useless to the military after the cold war.
D. It is indispensable in protecting endangered species.
