After a survey by a group of international experts, the beaches at Sharm el-Sheikh are to
reopen, but only after strict new safety measures are in place. There will be continuous patrols by boats close to shore.

Watch towers are being established along the beaches, manned by professional divers, equipped with binoculars to scan for any sign of sharks. Swimmers will have to remain within designated areas, and rules against feeding sharks or any other sea life are being reinforced.

The international shark experts concluded that recent attacks were carried out by more than one shark, so waiting until the culprit was caught seems not to have been an option before opening the beaches, especially as the peak Christmas season approaches. But tourists may be understandably nervous and at least some cancellations are reported.

26. What probably happened before the re-opening of the beach?_________

A. It must have been destroyed by a rainstorm.

B. It must have been visited by a dangerous shark.

C. Some people must have come here for suicidal.

D. There must have been a serious pollution.

27. Which of the following is NOT correct?_________

A. International experts surveyed the beach before its reopening.

B. Patrol boats are used to keep the beach under close watch.

C. People are not allowed to come to the beach.

D. Tourists do not come to the beach any longer.

28. Which of the following is NOT included in the safety measures?__________

A. Patrol boats.

B. Watch tower.

C. Professional divers.

D. International experts.

29. What can people do after the reopening of the beach?_________

A. Swim in designated area.

B. Feed sea animals except sharks.

C. Celebrate Christmas with professional divers.

D. Learn how to dive from professional divers.

30. Which of the following is correct?_________

A. Several sharks may attack together.

B. Sharks only attack at night.

C. The beach will be reopened till the culprit is caught.

D. The international shark experts patrol the beach every day.

Part A

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)

At an office in Hampton, Virginia, in the east of the United States, a team of ten net savvy workers sources the web for sexual content, from basic sex education to sex acts. This "quality assurance" team is making sure that the blocking component of Symantec's Norton Internet Security 2000 computer program remains effective. This is because there is widespread parental concern about blocking websites with sexual content from children.

Website blocking is nothing new—services like Net Nanny and programs like Cyber Patrol and Guard Dog have been around for a few years now, protecting children and reassuring parents that only wholesome websites are accessed by the youngsters. Net Nanny and Cyber Patrol will prevent access to any questionable sites when the program is in place,

Now Symantec says it has created a new category in consumer software with a package that combines website blocking with a "firewall", protecting your computer from hackers and viruses, as well as preventing careless disclosure of personal data. In short, Norton Internet Security, as the program is called, is designed to serve as the guardian of your digital health, keeping the bad things out and the private things in.

The Symantec program can be configured in many ways, the website blocking, for example, can be set to be either selectively permissive or total in its banning of websites, or switched off entirely. Also, Symantec's list of no-go areas, which on the CD now stand at around 36,000 addressed, is not confined to sex sites. The team in Virginia is also on the lookout for sites advocating drags, or which contain references to violence or gambling, and keeps a watch on chat rooms, e-mail services, entertainment portals—even job search and financial pages. These sites can be blocked by the program.

Computer users can also refresh the address list online with the Live update feature which is used by Norton Anti-Virus (which is bundled with NIS) to load the latest virus definitions. This service is free for the first year but, including virus definition updates; it costs $19.95 a year there-after.

The system is not perfect, however. Limited testing found the blocking of some "questionable" sites was not comprehensive. Trying to get access to a well-known US site such as Playboy results in an immediate blocking message with a standard invitation to report an "incorrectly categorized" site. By contrast, you could find in other countries such as New Zealand a sex site which declared itself to be "dedicated to providing sexual material, imaged, and anything a little bit unusual for sex enthusiasts all over the country.

What do we know from the first paragraph?

A.The net savvy workers are interested in searching the web for sexual content.

B.Parents want the workers to make sure that the blocking component works.

C.Parents across the world don't want the sexual websites to be blocked.

D.Parents across the world worry that their children might get hurt by some websites.

听力原文:A team of scientists recently began a project to measure the effects of loud nois

听力原文: A team of scientists recently began a project to measure the effects of loud noises on sea animals. If the sounds don't harm the animals, then the researchers can go ahead with a plan to transmit sound waves through the Pacific Ocean to take the earth's temperature. Sound travels faster through warm water than cold water. By analyzing the speed of sound through the ocean over time, the scientists will be able to determine if cur planet is warming up. The experiment was nearly cancelled more than a year ago because environmental groups fear that the sound will confuse or harm sea-animals. So scientists are conducting tests on the animals first. The researchers lowered a loud speaker that emits low frequency sound about 1,000 meters beneath the ocean. Scientists at the site transmit sound waves into the ocean. Radio transmitters attached to some of the sea animals help the researchers keep track of the animals' movements. If sea-animals are distressed by the sounds, they would swim away from the speakers. So far, there aren't any signs that the animals are being harmed. Researchers at the site noticed that large numbers of sea-animals swim near the speaker whether it was turned on or off, but it is still too soon to know for sure, the scientists admit. The test will continue through September. "If all goes well," they say, "we can begin measuring temperature changes on our planet."

(33)

A.To determine whether the Earth's temperature is going up.

B.To study the behavior. of some sea animals.

C.To measure the depths of the ocean.

D.To measure the movement of the ocean.
