     Do You Go To Sleep In Class?
     The "Acronym", our student newspaper, reports that most students go to sleep at 1: 30 a. m. Even if
that's an exaggeration (夸张), it's too close to the truth. Scientists say teenagers should sleep nine hours
each night. But that's hard to do.
     Some even "pull all-nighters". These are lazy students who have homework due (到期) the next day
that they haven't done. In the morning they don't look healthy and you can tell who has been doing it.
     One of my classmates did a survey (调查) on the problem. She found that most kids pull all-nighters to
finish homework, but some do it for other reasons, such as playing computer games!
     Maybe our lack of sleep is because of laziness-I think I'm a lazy student-or maybe it's because we have
too much to do in American high schools.
     I usually go to bed around midnight. If I stayed up past 1: 30 a. m, I wouldn't get any work done. I'd be
falling asleep at my computer. My classes begin at 7:30 a.m. I'm partly awake in my first class. By the
second, I'm slightly tired and sleepy. By my third class, I'm sleepy. By midday I'm finally wide-awake.
But by 3: 00 p. m., I'm slowing down again.
     Most American high schools seem to have such a problem.
     High school classes start at 7: 30 a. m., so students have to wake up one and a half hours before that to
get ready and catch the bus. It's believed that lack of sleep can damage both grades and health.
     Some schools are paying attention. Classes in those schools start at 8:30 a. m.
1. What's the problem talked about in the passage?
    A. Many kids have too much homework to do.
    B. Many teenagers don't have enough sleep.
    C. Many children are crazy about playing computer games.
    D. Many kids are too lazy to finish their homework on time.
2. The underlined expression "pull all-nighters" most probably means _____.
    A. 开夜车
    B. 上夜班
    C. 睡懒觉
    D. 补作业
3. Which of the following is NOT a reason mentioned in the passage?
    A. Laziness.
    B. Homework.
    C. Housework.
    D. Computer games.
4. What's the idea suggested at the end of the passage?
    A. Later start of classes.
    B. Less homework.
    C. Going to bed early.
    D. Eating healthy food.

There are many things we need to know, but we do not learn them at school. For example, if we want
to use our money wisely, we need to shop carefully. We need to know how to compare (比较) the prices
of the things in different shops. We also need to know how to make the best choice when we shop.
Knowing how to make such choices is a life skill, and we need to practice it in our daily life.

     Have you ever noticed background music? You can listen to it everywhere, restaurants, airports,
supermarkets, department stores… Background music is supposed to influence (影响) your attitudes
(态度) and mood (心情).
     Companies pay millions of dollars every year for background music. It's supposed to make you feel
better about yourself and the people around you. Factories use it a lot. It makes the workers happy and
work better. It is said (据说) that in a factory, music can increase the production by 4.5 percent.
Workers do not easily get tired if they listen to music all day. A worker in San Francisco said:" If the
music stops, somebody always runs to the telephone to complain about it. "Background music was
started during World War II when some factories had their own orchestras to keep workers happy and
calm . Now, of course, the music is piped in (以电讯设备传送) by a machine and different kinds of
music are played at different time in a day. For example, the music they play are faster at 10 than 8,
because workers are usually slower then.
     It's also very interesting that fast music is played in restaurants where hamburger is sold. Before
playing fast music, customers spent 22 minutes eating hamburgers. When they started playing fast music,
they found that a customer spent only 17 minutes eating! So they have more people coming in and out to
buy hamburgers. It's good for business. You can see why music has become so popular. In Los Angeles
(洛杉矶), for example, 30 different companies are selling background music services.
     The Xerox Corporation (静电复印公司) in Rochester, N．Y．(纽约州的罗切斯特市), spends
more than $80,000 a year for background music. Prison warders (狱警) use it. Farmers also use it to
keep their cattle calm. It's said that background music even influence plants.
