Many good parents feel that they have to punish their children once in a while. But other parents find that they can successfully manage without ever having to punish their children. This may depend on how the parents were brought up.

If they were punished occasionally for good reason, they naturally expect to punish their children in similar situations. And if they were kept in line by positive guidance alone, they tend to find that they can do the same with their children.

Before we go further with the subject of punishment, we ought to realize that punishment should never be the main element in discipline. The use of punishment is only a sign that the parents feel strongly about what they are saying. However, we all have seen children who have been slapped and spanked (打屁股), and yet remained ill­behaved.

The main source of good discipline is growing up in a loving family—being loved and learning to love in return. Habitual criminals are people who in childhood were never loved enough to make much difference to them. Many of them were also abused or were witnesses to significant violence.

Another vital element is children's intense desire to be as much like their parents as possible. They work particularly hard at being polite, civilized and responsible. They behave very seriously to take care of their dolls, keep house and go out to work, just as they see their parents do.

In automobile terms, the child supplies the power, but the parents have to do the steering (掌舵). For most children, most of the time, a disapproving glance or word from a parent is enough to direct the child back on the right track. Children's motives(动机) are good, but they don't have the experience or the stability to stay on the road. The parents have to keep saying. “We hold hands when we cross the street”， “It's time to go to bed so you'll grow up to be big and strong” and so on.

19．The attitude of parents towards punishment is decided by whether ________.

A．they believe in their power over their children

B．they have experiences of being disciplined

C．they were treated badly during childhood

D．they learned the role of punishment at school

20．The author probably supports the idea that ________.

A．punishment is the best way to discipline children

B．punishment helps parents teach their children properly

C．children from a loving family behave well

D．children will grow into loving people naturally

21．It can be learned from the text that ________.

A．most children tend to be ill­behaved all the time

B．children often learn behavior from their parents

C．children lack motivation to be well­disciplined

D．parents should let their children go their own way

22．In the author's opinion, what the parents should do is ________.

A．monitor their children and guide them when necessary

B．punish their children whenever they behave badly

C．make their children know what behavior is wrong

D．tell their children to copy their daily behavior

B

Good news for chocolate lovers: the treat preferred by millions all over the world is good for you, according to American researchers at the University of California. Chocolate contains substances called flavonoids that help maintain healthy hearts and good blood circulation. The researchers have discovered that cocoa acts like aspirin (阿司匹林), and eating a bar of chocolate has also been shown to release endorphins in the body: chemicals that help to reduce pain and stress.

The Olmec Indians of Mexico and Central America were the first to grow cocoa beans, in about 1500 BC, and the Mayans had been drinking unsweetened cocoa hundreds of years before it became fashionable in Europe.

In 1544, a delegation of Mayan nobles visited Philip of Spain and gave him jars of cocoa as a gift. Cocoa soon became fashionable in Spain and Portugal. The Spanish were the first to add sugar to their cocoa drinks.

By the middle of the century, solid chocolate was becoming familiar. In 1765, James Baker opened the first chocolate mill in the United States, introducing chocolate to the average citizen. In 1896, in Switzerland, Daniel Peter had the idea of adding milk in the chocolate­ making process, and produced the first milk chocolate.

Since then, chocolate has grown greatly in popularity. One of the biggest chocolate－eating nations is Britain, where the average man, woman, and child eats nine kilos of chocolate a year. In fact, chocolate is the number one comfort food, and there are more chocoholics in Britain than anywhere else in the world. Researchers warn that although chocolate is good for you, it should be eaten in small quantities—and with no milk added.

23．Why is chocolate good for the heart and blood circulation?

A. It reduces pain and stress.

B. It contains substances called flavonoids.

C. It releases endorphins in the body.

D. It acts like aspirin to protect the heart.

24．When cocoa was first introduced in Europe, it soon became fashionable as a ________.

A. gift　　　　　　　B. medicine

C. food             D. drink

25．What did James Baker do with chocolate?

A. He introduced it to Europe.

B. He added sugar to it to make chocolate bars.

C. He made chocolate accessible to the average man.

D. He produced the first milk chocolate.

26．Which of the following statements is NOT true, according to the text?

A．Chocolate is healthy if it has milk added.

B．Chocolate is loved by millions of people worldwide.

C．Chocolate contains substances that make people feel good.

D．Eating chocolate occasionally is healthy.

四、短文改错。

【答案】

27.studies改成study

28.has 改成 is

29.kind 改成kinds

30. borrowed改成borrow

31.a改成the

32.their 改成our

33.I前面加What

34. or改成and

35. in去掉

36.Have 改成Having

【解析】

27.studies改成study 考查主谓一致。主语是A large number of students复数形式，故谓语动词用原形。

28.has 改成 is 考查there be句型，某地有某物，表存在用there be句型，且后面跟的是a big library单数，故用is。

29.kind 改成kinds 考查单复数。我们可以借我们喜欢的不同种类的书，不同种类的是复数，故kind用复数形式。

30. borrowed改成borrow 考查时态。全文都是一般现在时，这里也应该用一般现在时，故borrowed改成borrow。

31.a改成the 考查冠词。这里的library是上文提到过的，所以用定冠词。

32.their 改成our 考查代词。全文都在讲我的学校，用的都是第一人称，所以这里应该用第一人称，故their 改成our。

33.I前面加What 考查主语从句引导词。本句的主语应该是个从句，故在I前面加What。

34. or改成and 考查连词，come 和fly是两个并列的动词，所以把or改成and。

35. in去掉 考查介词。已经有了介词next to, 教室在花园旁边，所以in多余，应该去掉。

36.Have 改成Having 考查非谓语动词。这里Have classes in such a beautiful environment做伴随状语，且主语we和动词have是主动关系，所以把Have 改成Having。

五.书面表达。

We are facing more and more serious challenges from global warming. The ice is melting and the sea level is rising. Coastal cities and their residents are in danger.

However，even we ordinary people can do something to help. First，we should start making use of clean energy. For example，we can use solar and wind energy to replace coal and oil. Moreover，we should take public transportation instead of driving cars. This can reduce the emission of carbon dioxide. Finally，we should grow more trees and plants since they can absorb carbon dioxide and other pollutants in the air.

Global warming is something everyone needs to be concerned about. It’s time for all of us to do what we can to help protect our earth.
