2. Passage Twenty-Five Online dating has just been revealed to be one of the most common ways to start a relationship. But new research reveals that the concept is still highly flawed (有缺陷的). An analysis of 400 studies into online dating shows that while it offers access to plenty of other singles， users can be overwhelmed and put off by the volume of choice， defeating the purpose. The research， by Northwestern University and published in the journal Psychological Science in the public interest， found that the processes involved don’t lend themselves to forming strong relationships. The findings also indicated that the concept of an online profile (介绍) is not entirely useful and “can result in treating potential partners as mere objects ”. Lead author Eli. J. Finkel explained， “Online dating is a terrific addition for singles to meet. However， there are two problems. ” First， studying over seemingly endless lists of profiles of people one does not know， as on Match.com， does not reveal much about them. Second， it “overloads people and they end up shutting down，” he said. He compared it to shopping at “supermarkets of love” and said psychological research shows people presented with too many choices tend to make lazy and often poor decisions. The study’s authors also questioned the algorithms ( 算法) employed by sites such as eHarmony.com to match people based on their interests or personality—comparing it to having a real estate agent of love. While the algorithm may reduce the number of potential partners from thousands to a few， they may be as unsuitable for each other as two people meeting at random， Dr. Finkel explained， adding the chances are no better than finding a relationship by walking into any bar. “There’s no better way to figure out whether you’re a match with somebody than talking to them over a coffee or beer，” Dr. Finkel said. According to Paragraph 2， online dating ( ) .

A. attracts a limited number of singles

5. Passage Eleven 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 breast cancer. Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm and reasonable way. Others burst with anger， screaming and yelling. But still others keep their anger inside. They cannot or will not express it. This is called 【repressing】 anger. For years some doctors claim that both repressing and expressing anger can be dangerous. They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙). They spend the heart rate， raise blood pressure or sugar level in the blood. As a result， the angry person feels excited and is ready to react. The violent reaction may lead to high blood pressure. However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it. They believe that those who keep their anger inside may face a greater danger of heart disease. Most doctors agree that it is important to learn how to deal with anger. They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about. If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably. They also believe that a good way to deal with anger is to find humor in the situation that has made you angry. After all， it is much healthier to laugh than to get angry .What is the tone of this passage?

A. Neutral.

B. Negative.

C. Emotional.

D. Entertaining.

5. Passage Twenty-Two Though some people have suggested that women should return to housework in order to leave more jobs for men， the idea has been rejected by both women and men in public opinion polls (民意测验). Lately some union officials have suggested that too many women are employed in type of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women—especially women in their childbearing years actually delay economic development and result in lower productivity， poor quality and inefficiency. To solve the problem， they have suggested that the working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances， families would retain their same level of income， and women could run the house and raise children much better. The suggestion has been rejected by 9 out of 10 people polled. A hundred persons in a big city were questioned last summer. Out of 50 women， 46 said they were unwilling to leave their jobs， no matter what the situation was. The other 4 said they would like to return home if their jobs could be taken by their sons or daughters. Of 50 men polled， only 6 said they would like to see their wives give up their jobs， if it meant higher wages for themselves. Some other people have suggested another way called “phased employment theory” . The theory suggests that a woman worker take leave from her job when she is seven months pregnant (妊娠) and stay off the job until her baby reaches the age of 3. It suggests that women on leave receive 75 percent of their normal salary and be allowed to return to work after the 3-year period. This will benefit children， women， their families and the society. Some of those polled， both women and men， felt the idea is a good one. It definitely seems to be more acceptable than the suggestion that women return to home forever. According to the “phased employment” theory， during a woman’s leave from her job

A. her work should be done by her husband or brothers

B. either her husband or her brothers will be given double wages

3. Passage Seventeen No one knows how man learned to make words. Perhaps he began by making sounds like those made by animals. Perhaps he grunted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him——water splashing， bees humming， a stone falling to the ground. Somehow， he learned to make words. As the centuries went by， he made more and more new words. This is what we mean by language. People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. Each contains many thousands of words. A very large English dictionary， for example， contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life. The words you know are called your vocabulary. You should try to make your vocabulary bigger. You’re supposed to read as many books as you can. There are plenty of books written in easy English for you to read. You will enjoy them. When you meet a new word， you should find it in your dictionary. Your dictionary is your most useful book. People from different countries ( ) .

A. made same words

B. made different kinds of words

C. had a same language
