Searching the Internet may help middle-aged and older adults keep their memories sharp,US researchers said.

Researchers at the University of California, Los Angeles ,studied people doing web searches by recording their brain activity.

“What we saw was people who had Internet experience used more of their brain during the search,”Dr.Gary Small, a UCLA expert on aging, said,“This suggests that just searching on the Internet may train the brain and that it may keep it active and healthy.”

“This is the first time anyone has simulated(模拟)an Internet search task while scanning the brain,”Small said. His team studied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching the Internet and the other half had no web experience. However, the two groups were similar in age, gender and education.

Both groups were asked to do Internet searches and book reading tasks while their brain activity was monitored.

“We found that in the book reading task, the visual cortex— the part of the brain that controls reading and language — was activated,”Small said,“In doing the Internet search task, there was much greater activity, but only in the Internet-savvy(了解)group.”

He said it appears that people who are familiar with the Internet can engage in much deeper level of brain activity. Activities that keep the brain engaged can preserve brain health and thinking ability. Small thinks learning to do Internet searches may be one of those activities.

To me, life without music would not be exciting. I realize that this is not true for everybody. Many people get along quite well without going to the concert, and listening to the record. But music plays an important part in everyone's life, whether he realizes it or not. Try to imagine, for example, what films or TV plays would be like without music. Would the feelings, the moving plot, and the greatest interests, be so exciting or dramatic? I'm not sure about it.

Now, we have been speaking of music in its more common meaning----the kind of music we hear in the concert hall. But if we look at some parts of music more closely, we discover them in our everyday life too----in the rhythm of the sea, the melody of a bird in the woods and so on. So music surely has meaning for everyone, in some way or other. And, of course, it has special meaning for those who have spent all their lives working on playing or writing music.

It is well said, “Through music a child enters into a world of beauty, expresses himself from his heart, feels the joy of doing things alone, learns to take care of others, develops his mind and makes his body strong.”

1. What dose the writer say more about in the text?

A.Life full of music.

B.Life without music.

C.The importance of music.

D.The development of music.

2. From the text, we learn that many people________.

A.don't realize the importance of music

B.get along quite well without music

C.go to the concert instead of enjoying music

D.think music would be less exciting than films

3. What does the underlined word “melody” mean in the text?

A.flying             B.looking           C.singing            D.living

4. From the last paragraph, we learn that music________.

A.is very important, especially for children

B.is very necessary for our everyday life

C.can make our life exciting and dramatic

D.can enter into another beautiful world

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes (放松) little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts (变换) back and forth from one level of sleep to the other.

Though your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend (建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.

1.The text suggests that not getting enough sleep might make you _____.

A.suffer from poor health

B.feel tired and nervous

C.dream more often

D.breathe quickly

2.During REM, _____.

A.you move restlessly

B.you start dreaming

C.your mind stops working

D.your eyeballs move quickly

3.The underlined word "drowsy" in the last paragraph probably means _____.

A.lazy              B.sleepy            C.relaxed           D.pleased

4. A good title for this text might be _____.

A.Dreams                               B.Sleep

C.Good Health                           D.Work and Rest

If you think you’ve gained too much weight or are too skinny, you can talk to a doctor. Your doctor will tell you 1. ______________.

If it is concerned about your height, weight, or BMI (体重指数), your doctor may ask questions 2. ______________.

The doctor can then put all the information together to decide 3. _____________.

If your weight isn’t in a healthy range, you will probably get specific diet and exercise recommendations based on your individual needs.

In a few cases, teenagers can be underweight because of a health problem that needs treatment. If you feel tired or ill a lot, or 5. ____________, or other problems that have lasted for more than a week or two, be sure to let your parents or your doctor know.
