Pretoria, South Africa – Hundreds of swimmers play in the water along a South Africa beach. Suddenly a huge shark appears off shore and heads for the bathers. Before it can get close to the swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns away from the shore and heads out to sea, leaving the swimmers untouched.
Such a scene will soon become common along shark-in-fasted (鲨鱼成群的) shores. An electrical engineer from the University of Pretoria has developed an electrical system that repels (击退) sharks by controlling their movements. Confused by this action, the sharks end up turning away from the beach.
In this unusual shark-repellent method, an insulated (绝缘的) cable is buried on the bottom of the sea around a beach where people swim. When an electric current is sent through the cable, an electric field is produced in the water above the cable.
When shark swims into the electric field, nerve cells just below the shark' s skin will sense the field. The electricity produces a reflex (反射作用) action in the shark' s muscles, causing the dangerous animal to swim parallel to the cable. Confused by increasing loss of control of its muscles, the shark suddenly changes its direction and heads seaward, away from the electric field.
In a test of the invisible new shark-repellent system, a cable was placed around a beach in St. Lucia, an island around the beach a long time ago to keep sharks away from swimmers, and a net was left in place during the experiment.
When the electric field was left on for more than a year and a half, no sharks were found in the net. However, when the power was turned off,89 sharks ended up in the net.
Using the electric-wall method instead of net to protect bathers would avoid the needless death of many sharks, said biologists. Currently, thousands of sharks die each year when they become trapped in protective nets that surround holiday resorts in Africa and Australia.  About 10 to 15 humans are killed by sharks annually.

D．Using the electric-wall instead of nets would avoid the needless death of many sharks.

IQUIQUE, Chile (Reuters) — Rescue workers at the San Jose gold and copper mine in northern Chile had reason to sing this week. A small hole drilled into the earth became a passage to freedom for 33 trapped miners, who spent 69 days underground. “Never have people been trapped for so long so deeply,” says a doctor at NASA, the American space agency, which helped in the rescue.

But the chief medical officer for the miners said most are in good enough health to leave the hospital within a day or so. The first three recovered and went home Thursday night.

For much of the day the miners relaxed with Chilean President Sebastian Pinera. The 32 Chileans and 1 Bolivian still wore special sunglasses to protect their eyes.

A partial mine collapse on 5th August trapped them more than half a kilometer underground. They had to stretch a two-day food supply. For two weeks no one knew if they were alive or dead. Later, they received supplies.

The first miner rescued on Wednesday was Florencio Avalos. The second was Mario Sepulveda, who talked about how the experience tested his faith. The last miner up was Luis Urzua, who was the shift leader when his crew became trapped.

Rescuers used a metal cage to pull the miners to safety in less than 24 hours — faster than expected. The rescue capsule was a half-meter wide and known as the Phoenix, an imaginary bird from ancient stories. It bursts into flames but is continually reborn and rises from the ashes.

Chile’s Navy built the capsule with advice from mining experts and NASA engineers. It worked like an elevator, traveling up and down on a cable through a shaft（竖井）drilled 622 meters into the rocks.

Millions of people around the world watched the rescue. More than one thousand journalists traveled to the mine in the Atacama Desert to report on the rescue. They joined family members of the miners and rescue crews housed in an area of tents known as Camp Hope.

What would be the best title for the passage?

   A. Rescued miners speak out

   B. Miners’ life deep underground

   C. A rebirth for 33 rescued miners in Chile

   D. Chilean president honors rescued miners

How many rescued miners are still in hospital?

   A. 3.                 B. 30.                     C. 33.             D. 69.

We can infer from the passage that ______.

   A. all the trapped miners are Chileans

   B. the Chileans rescued the miners alone

   C. the rescue caught the world’s attention

   D. the trapped miners lived easily underground

Which of the following is true of the Phoenix?

   A. It was a wooden cage like a capsule.

   B. It worked efficiently in the rescue.

   C. It was named after a real Chilean bird.

   D. It was built by NASA engineers.

The rescue is great for the reason that ______.

   A. 33 trapped miners were saved

   B. the American space agency took part

   C. Chilean President was on the rescuing spot

   D. it lasted so long and the miners were trapped so deep

What would be the best title for the passage?

After a lot of weightlifting and 25 exhausting days training, a 52-year-old woman recently became the first female “gripman” on San Francisco’s historic cable cars.

Fannie Barnes passed her written test and completed a final run under the watchful eye of a supervisor, Municipal Railway spokesman Alan Siegel said.

Deep calluses(茧) are already forming at the base of her fingers and there is a hole in her glove. Two other women quit after a single day with injured muscles. “Now they’re going to have to change the word from gripman to grip person, just because of me,” Barnes said earlier, “I’m so excited.”

After almost a year of serious workouts, Barns can pull more than 61 kilos, only 23 kilos less than her body weight. And she’ll need the muscle, for this is no modern, push-button technology. Every time a car starts up again after making a stop, the gripman must haul back on a lever controlling a device that grips the cable, which runs continuously at 14 kilometers per hour. If the grip slips, so does the car. A second person operates the brakes.

In addition to having to throw her weight around on the job, she’s got to throw out some attitude to men who were hard to convince. The city employs 76 men in the job.

“A lot of men said mean things to me and didn’t want to help train me. But I would like to thank the guys who were against me because they gave me even more inspiration to do it.” she said.

Not all the men were against her. Many of the male colleagues yelled out support as she did her training runs. One of her biggest tests was drizzly December morning. She first went down the Hyde Street Hill, considered the most dangerous incline on the cable car routes. “I had to have the will and I had to believe I could do it,” she said. “It was scary, but as I started going down full grip and felt that I was in control, I knew I was on my way,” Barnes already is a pioneer of sorts. She started working as a cable car conductor six years ago, collecting fares and assisting on the back brake. She is one of only three women to have that job. But she said she always wanted the job up front on the car. (400)

What is unusual about Fannie Barnes getting a job as a gripman?

 A. She is the oldest one to work as a grpman.

 B. She is the first women to work as a gripman.

 C. She is the fattest women to work as a gripman.

 D. She is the most suitable one to work as a gripman.

What did the 52-year-old woman do when she first began working on the city’s cable car?

 A. As a gripman.    B. As a conductor.    C. As a brakeman.  D. As a supervisor.

It can be inferred from the passage that Fannie Barnes is ________.

A. strong and easy-going            B. strong-willed and self-confident

C. popular and humorous            D. considerate and quick-tempered

The rise of multinational corporations （跨国公司）, global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR．

　　Surprisingly, since modern PR was largely an American invention, America’s relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world’s top five public relations agencies were American-owned． In 1991, only one was． The British in particular are becoming more sophisticated and creative． A recent survey found that more than half of all British companies include PR as part of their corporate （公司的） planning activities, compared to about one-third of U.S. companies．It may not be long before London replaces New York as the capital of PR．

　　Why is America lagging behind in the global PR race? Firstly, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs． Knowledge of world geography, for example, has never been strong in this country． Secondly, Americans lag behind their European and Asian counterparts （相对应的人） in knowing a second language． Less than 5 percent of Burson—Marshall’s U．S．employees know two languages． Ogilvy and Mather have about the same percentage． Conversely, some European firms have half or more of their employees fluent in a second language． Finally, people involved in PR abroad tend to keep a closer eye on international affairs． In the financial PR area, for instance, most Americans read the Wall Street Journal． Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country．

Perhaps the PR industry might take a lesson from Ted Turner of CNN （Cable News Network）． Turner recently announced that the word “foreign” would no longer be used on CNN news

broadcasts. According to Turner, global communications have made the nations of the world so interdependent that there is no longer any such thing as foreign．

1.Compared with the American PR personnel, what is/are an advantage (s) of the non-Americans involved in PR?

A． They tend to be more internationally minded

B． They speak more and better foreign languages．

C． They usually pay more attention to global financial situation．

D． Both A and B．

2.What is the immediate cause of the downfall of America’s public relations?

A．The number of US public relations agencies had greatly decreased by 1991．

B．Other countries have increased their efforts in public relations．

C．On the global scale, cultural differences have significantly shrunk．

D．The British companies are becoming especially sophisticated and creative in public relations．

3.It could be inferred that the author of the passage is______．

A．an American       B．a Briton           C．Ted Turner         D．an Asian

4.The underlined word “provincial” in paragraph 3 could possibly mean “      ”．

A．strict in thinking                        B．like people from rural areas

C．limited in outlook                       D．interested in geographical knowledge
