A

A higher reading rate, with no loss of comprehension, will help you in other subjects as well as in English, and the general principles apply to any language. Naturally, you will not read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook-but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage gained will be the same whatever kind of reading you are concerned with.

The reading passages which follow are all of an average level of difficulty for your stage of instruction. They are all about five hundred words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding at four hundred words per minute, you might skim (浏览) through a newspaper at perhaps 650-700, while with a difficult textbook you might drop to two hundred or two hundred and fifty.

Perhaps you would like to know what reading speeds are common among native English-speaking university students and how those speeds can be improved. Tests in Minnesota, USA, for example, have shown that students without special training can read English of average difficulty, for example, Tolstoy's War and Peace in translation, at speeds of between 240 and 250 words per minute with about seventy percent comprehension. Students in Minnesota claim that after twelve half-hour lessons, once a week, the reading speed can be increased, with no loss of comprehension, to around five hundred words per minute.

According to the passage, the purpose of effective reading with higher speed is most likely to help you ________.

A. only in your reading of a physics textbook

B. improve your understanding of an economics textbook

C. not only in your language study but also in other subjects

D. choose the suitable materials to read

Which of the following does not describe the types of reading materials mentioned in the second paragraph?

A. Those beyond one's reading comprehension.

B. Those concerned with common knowledge.

C. Those without much demand for specialized knowledge.

D. Those with the length of about five hundred words.

The average speed of untrained native speakers in the University of Minnesota is ________.

A. about 300 words per minute

B. about 245 words per minute

C. about 650-700 words per minute

D. about 500 words per minute

According to the passage, how fast can you expect to read after you have attended twelve half-hour lessons in the University of Minnesota?

A. You can increase your reading speed by three times.

B. No real increase in reading speed can be achieved.

C. Yon can increase your reading speed by four times.

D. You can double your reading speed.

A newly-published study has shown that loneliness can spread from one person to another, like a disease.

Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.

Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.

University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.

Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.

The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.

The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.

Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.

The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.

What is true about the Framingham Study?

A. It was only conducted in 1948.        B. It involves more than 12,000 participants.

C. It was led by John Cacioppo          D. It showed that any behavior could spread.

From the passage, we can learn that            .

A. the habit of littering doesn’t spread

B. a lonely person won’t have friends

C. everyone may be affected by others’ loneliness

D. lonely people don’t know the cause of their loneliness

Which statement about the spread of loneliness is true?

A. The spreading effect was the second strongest among friends.

B. No spreading effect was found on husbands and wives.

C. Women are more likely to be affected than men.

D. Brothers are more easily affected than neighbors.

If you make 10 more friends in a year, the days of your feeling loneliness will be reduced by            .

A. 48 days          B. 25 days      C. 20 days      D. 15 days

What is the main idea of the passage?

A. Actions should be taken to help lonely people.  B. People feel lonely for many reasons.

C. Ways to fight against loneliness.             D. Lonely people can affect others.

A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. And the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.
The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
