It is not unusual to see your desk-mate yawn (打呵欠) as he complains that he didn't have a good sleep the night before. Many teens don't get enough sleep because they have too much homework, which keeps them up at night. Some teens cannot sleep at night even when they want to.

Studies show that during your teenage years, the body's biological clock is reset, telling you to sleep later at night and wake up later in the morning.

But changes in the body clock aren't the only reason teens lose sleep. Lots of people have insomnia (失眠). The most common cause of insomnia is stress. But all sorts of things can lead to insomnia. These include physical discomfort, emotional troubles and even sleeping environment. It's common for everyone to have insomnia from time to time. But if it lasts for a month or more go and see a doctor.

Some people have a condition that causes stomach acid (酸) to move backward towards the chest. This produces the uncomfortable, burning feeling called heartburn. So even if the person doesn't notice the feelings of heartburn because he is sleeping, he may feel tired the next day.

Most teens have nightmares sometimes. But, if they are frequent, a person's sleep pattern can be seriously affected. The most common cause of nightmares is emotional problems, such as stress (压力) or anxiety. If you have them a lot, it's a good idea to talk to a doctor.

Doctors encourage teens to make lifestyle changes to develop good sleeping habits. You probably know that coffee can keep you awake, but did you know that playing video games or watching TV does the same?

The average person learns most of the 30 000～40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious(意识到的) effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently(永久的)by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it.

Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious(认真的), write the word and its meaning in a personal vocabulary list — preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days.

Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read.

Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing them enables you to make intelligent guesses about the meaning of words.

If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited(继承) or borrowed much of its vocabulary of 500 000～600 000 words from Latin, Greek, French, Spanish and German.

When you meet a new word in reading, what should you do?

A. Guess its meaning.                           B. Ask somebody.

C. Look it up in a dictionary.                     D. All of the above.

According to this passage, the best way to build a good vocabulary is _______.

A. to remember a lot                              B. to read a great deal

C. to take part in a lot of good talks            D. both B and C

The phrase “be alert to” in the third paragraph may best be replaced by “_______”.

A. look at                                        B. pay attention to 

C. write down                                  D. learn by heart

In the fourth paragraph, the word “them” refers to _______.

A. the parts of words            B. prefixes    C. suffixes                         D. roots

I am an e-mail user. When I first started to use the e-mail system I used to read all my e-mail. I didn’t have much mail. I was very excited about receiving any e-mail. I gave my friends my e-mail address. Soon I had more mail than I wanted. Some of the mail was junk mail. I was worried. I didn’t want my mail to control me.
I’ve tried some methods to help me get control of my mail. First, I check my mail at the same time every day. Also I try to allow myself only 15-20 minutes every day to process my e-mail. This doesn’t always work, but I try. Sometimes I save the messages. Sometimes I just read them, maybe answer a few, and then delete them.
Sometimes I’m not at all interested in a message, so I don’t even open it. I delete it right away. This is very much the way I go through the mail that the postal service delivers to my home.
These methods are very simple. I have some friends who are very clever with computers. From time to time, they teach me new tricks for managing my e-mail. I’ve also learned to transfer some messages to a disk so they don’t fill up my mail files. Then I can read them later and maybe use them in my work. I’m still amazed at what e-mail can do for me! I’m still worried, however, about having too much to read.

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc．In general the person feels excited and ready to act.

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger ferociously may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger.

Pushing children too hard is a really big social problem that seems to be getting worse．Now we have 6-month-olds in music classes and swimming classes．Parents fear that if other children are attending these classes，they will be holding their own children back if they do not enroll，too．

    The other extreme，simply taking a laissez-faire approach and letting children do—or refuse to do—whatever they want，is not the answer either，of course．

    Dr Taylor emphasizes that parents need to push their children based on what is best for the children，not what is best for themselves．If children understand that an activity is in their best interests，then they will accept it, he finds．

    Dr Taylor and other family experts remain pessimistic about the possibilities for widespread social change．“The force of our popular culture，driven by money and superficial（表面上的） values，cannot be resisted，” he says．But change can take place at a“micro-level,” in families and schools．

    When changes do occur，the rewards can benefit everyone in the family．One mother supporting this new approach toward parenting mentions the advantages her family experienced after her children cut back on activities．“The biggest thing is that since we have done this，we are rested,” she says．“Not only are our kids rested，because they're not in a ton of stuff, but my husband and I are rested，because we're not driving them everywhere．We weren’t living in the moment when we were always busy．We were living by the schedule．The return on our investment of spending time together has been enormous．”
