Some students get so nervous before a test, they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry, it actually uses up attention and memory resources.I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher, Gerardo Ramirez, have developed a possible solution. Just before an exam, highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “what we think happens is when students put it down on paper , they think about the worst that could happen and they reappraise the situation. They might realize it’s not as had as they might think it was before and, in essence(本质上), it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B+, compared to a B- for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious, who’d done our writing intervention, all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.

In a little-known part of the counter-terrorism(反恐怖主义) world, one of the most effective detection systems is a 600-pound animal that works for about 20 pounds of fish a day.

Since the 1960s, the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers, to recover inert torpedoes(鱼雷)and to test objects used in Naval exercises.

Program officials estimate that the sea lions in the Marine Mammal Program have recovered millions of dollars of U.S. Naval torpedoes and instrumentation dropped on the sea floor.

The U.S. Navy kept its Marine Mammal Program a secret until the 1990s, and this spring CNN became one of only a handful of media outlets to see firsthand how the program works.

The program has trained about 75 Pacific bottlenose dolphins, with natural biosonar (生物声纳) that tracks better than any manmade device; and 35 California sea lions, with superb underwater eyesight.

Not only do these trained marine mammals track and retrieve millions of dollars in U. S. military equipment, they are also helping to save lives.

The Navy won't disclose whether the dolphins and sea lions have effectively intercepted (阻拦)terrorists attempting to do harm to any U.S. facilities.

"Either way, it serves as a deterrent(阻碍) effect." says Christian Harris, operations supervisor for the program. The mammals can be deployed(调动) via C-130 cargo aircraft to perform their missions anywhere in the world within 72 hours. They have been used in exercises from Alaska to Hawaii, operating in great temperature and environmental ranges. They also have the capability to operate off vessels.

Dolphins most recently were deployed in the Iraq war, performing mine detection and clearance operations in the Persian Gulf to ensure safe passage for humanitarian ships delivering aid. Some of these Iraq war "veterans" are now back home, tasked with a new mission: guarding nuclear submarines in their homeports of Bremerton, Washington, and Groton, Connecticut.

1.The underlined word "retrieve" in Paragraph 6 can be replaced by ________.

A.find out           B.recover           C.save             D.detect

2.Which is NOT the purpose of the Marine Mammal Program?

A.To detect sea mines and swimmers.

B.To save lives of people.

C.To recover inert torpedoes.

D.To help the U.S. Naval test equipment.

3.What can be inferred according to the text?

A.These trained marine mammals eat pounds of fish a day.

B.The U.S. Navy performed the Marine Mammal Program for about 30 years secretly.

C.These mammals can carry out a task everywhere.

D.A lot of countries will train dolphins and sea lions for anti-terrorism.

4.What would be the best title for the passage?

A.The Special Skills of Marine Mammals        B.The U.S. Anti-terrorism Program

C.Exceptional Anti-terrorism Member         D.Trained Marine Mammals
