听力原文：American scientists have found that some birds are more intelligent than experts

听力原文： American scientists have found that some birds are more intelligent than experts had originally believed. The scientists say birds have abilities that involve communication and different kinds of memory. In some unusual cases, their abilities seem better than those of humans.

Griffin is a Grey parrot. He lives in his laboratory at the Massachusetts Institute of Technology in Cambridge. Griffin can arrange objects in order of size. He can also combine words in the right order. For example, he will combine words when asking for a piece of food.

Some birds have other memory skills. For example, they collect and store thousands of seeds in autumn, and find them later in winter. These birds use natural objects to find the seeds they have stored. They use at least three objects, such as rocks or trees, to find the stored seeds.

A jay can be trained to choose one object instead of another. The bird uses this skill to receive a prize, such as food.Scientists also say some birds can learn as many as two thousand different songs. They say songs may have developed as a way for birds to communicate with other birds.

Scientists believe that birds must have a special guidance system in their brain. Understanding how a bird's brain operates may help us better understand how a human brain processes information.

(26)

A．Talking.

B．Communication and memory.

C．Singing.

D．Finding the way.

听力原文：More and more people are immigrating into the United States. The growing numbers

听力原文： More and more people are immigrating into the United States. The growing numbers of new immigrants have caused some tensions. Asian-Americans are concerned about a number of anti Asian incidents in the last five years. Some of the incidents involved racial insults. Some involved violence.

The United States Civil Rights Commission reported last autumn that anti-Asian violence is a national problem. Social experts say some Americans are looking for someone to blame for the country's economic problems. These people believe Japan is responsible for the trade imbalance and loss of industrial jobs. So they blame anyone who, to them, looks like Japanese... or simply Asian. This feeling is strongest, experts say, among poorer Americans who are struggling for survival.

Partly because of this problem, Asian-Americans are becoming more politically active. They are speaking out against anti-Asian violence and against policies based on anti-Asian feelings.

Traditionally, Asians have taken little part in politics in the United States. They put their energy into hard work and taking care of their families. Now, a movement for more political power has begun.

Asian-American politicians say the reason is mainly the desire for political representation. They say all Asian Americans do not share the same political goals, but share a desire to end all forms of racism. These political leaders would like to see more Asian-Americans in political life. California politician Jule Tang believes that Asian-Americans will become a united political force with their own elected officials. Ms. Tang says, "Asians want to be really part of the American system."

(33)

A．Some Americans look down upon Asian-Americans.

B．Some Americans blame China for the trade imbalance.

C．Some Americans blame Japanese for the trade imbalance and loss of jobs.

D．Americans think that they lost their jobs because Asian-Americans have taken the job places.

Taking a Nap during the Day

Medical experts say most Americans do not get【51】 sleep. They say more Americans need to rest for a short period in the middle of the day. They are advising people to sleep lightly before【52】 with other activities.

One study earlier this year found that persons who sleep for a few minutes during the day were less【53】 to die of disease. The study followed more than 2,300 Greek adults【54】 about six years. Adult who rested for half an hour【55】 three times a week had a 37 percent lower risk of dying from heart disease than those who did not nap.

Study organizers said the strongest evidence was in working men. They said naps might improve【56】 by mitigating tension caused by work.

Some European and Latin American businesses have supported the【57】 of napping for many years. They urge people to【58】 work, go home and have a nap before returning. In the United States, some companies let workers rest briefly in their offices. They believe this reduces【59】 and accidents, and【60】 increases the amount of work a person can do.

Sleep experts say it is likely that people make more mistakes at work than at other times. They say people should not carry out important duties when they feel【61】. And they say the best thing to do is to take a nap. About twenty minutes of rest is【62】 you need. Experts say this provides extra energy and can increase your effectiveness【63】 the end of the day. But experts warn that a nap【64】 last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be【65】.
