The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? __71__ It’s similar to the music you listen to, but it’s not exactly the same. That’s because this music was especially designed to relax you, or to give you extra energy. Sometimes you don’t even realize the music is playing, but you react to the music anyway.

   Quiet background music used to be called “elevator music” because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name “Muzak”. About one-third of the people in America listen to “Muzak” every day. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. __72__

   If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don’t want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? __73__

   Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. __74__ Supermarket shoppers buy 38 percent more groceries.

   __75__ They say it’s boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!

A.       Some people don’t like Muzak.

B.       The music gives them extra energy.

C.       Music is playing in the background.

D.       Factory workers produce 13 percent more.

E.       Muzak tends to help people understand music better.

F.       They get as much as $ 4 million a year if their songs are used.

G.       Muzak is played in most of the big supermarkets in the world.

阅读与回答问题；请认真阅读下面短文，并根据短文内容回答问题。

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can’t they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn’t a cure for each one.

When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a block in it. You feel terrible because you can’t breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells（细胞). You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths and drink warm liquids. Other people take medicine to stop different symptoms(症状)of colds.

There is one interesting thing to note—some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn’t have a way to fight it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:

It takes about one week to get over a cold if you don’t take medicine, but it takes only seven days to get over a cold if you take medicine.

诗歌鉴赏

16.选择填入横线上合适的一项是（2分）

①王夫之在《姜斋诗话》中说：“以乐景写哀，以哀景写乐，倍增其哀乐。              ，就是以乐景写哀情的例证。
