Since the Second World War，there has been an obvious trend，especially among the growing group of college students，toward early marriage. Many youths begin dating in the first stage of adolescence, "go steady" through high school, and marry before their formal education has been completed. In some quarters, there is much shaking of graying heads over the unacceptable ways of youth. However, emotional (情感的）maturity does not grow with age； it does not arrive automatically at twenty -one or twenty-five. Some achieve it surprisingly early, while others never do, even in three-score years and ten.

Many students are marrying as an escape, not only from an unsatisfying home life, but also from their own personal problems of loneliness. However, any marriage 'entered into as an escape cannot prove entirely successful. The sad fact is that marriage seldom solves one' s problems ； more often，it merely worsens them. What ’ s more，it is doubtful whether the home is able to carry all that the young are seeking； they might abandon one idol(幻像）only to have another. Young people correctly understand that their parents are wrong in believing that success is the most important in life，but they themselves are wrong in believing that they have found the true center of life' s meaning. Their expectations of marriage are basically unrealistic and therefore can not be met. They want too much, and tragic disillusionment(幻想破滅）is often likely to follow.

Shall we, then, join the chorus of those against early marriages? One cannot generalize： all early marriages are bad and all later ones are good. Satisfactory marriages are determined not by how old one is, but by the emotional maturity of the partners. Therefore, each case must be judged on its own benefits. If the early marriage is not an escape, if it is entered into with relatively few false expectations，and if it is economically workable，why not? Good marriages can

be made from sixteen to sixty, and so can bad ones.

The underlined phrase ” shaking of graying heads， refers to______.

A.  the anger of parents

B.  the disapproval of elderly people

C.  the improper behaviors of the young

D.  the emotional expectations of young lovers

The author thinks the idea of marriage as an escape is______.

A. acceptable   B. controversial C. immature    D. unreasonable

The author argues that______.

A.  young people can benefit little from early marriage marriages

B.  elderly people are wrong about early marriages

C.  early marriages are not always unsuccessful

D.  early marriages should not be encouraged

What’ s the main idea of the passage?

A.  Young people，s failure in marriage results from disillusionment.

B.  Young people shouldn' t have many expectations for marriage.

C.  Successful marriages depend on emotional maturity.

D.  Home is the place where you get rid of loneliness.

Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the children. Before they can speak, many children will also ask questions by gesture and by making questioning noises.

Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation(模仿) leads on to deliberate(有意的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.

It is a problem we need to get our teeth into. The meaning of a word depends on what a particular person means by it in a particular situation; and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use, at seven months, of “mama” as a greeting for his mother cannot be dismissed as a meaning-less sound simply because he also uses it at another time for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.

Before children start speaking _______.

A. they need equal amount of listening

B. they need different amounts of listening

C. they are all eager to cooperate with the adults by obey spoken instructions

D. they can’t understand and obey the adult’s oral instructions

Children who start speaking late _______.

A. may have problems with their listening

B. probably do not hear enough language spoken around them

C. usually pay close attention to what they hear

D. often take a long time in learning to listen properly

A baby’s first noises are _______.

A. an expression of his moods and feelings

B. an early form of language

C. a sign that he means to tell you something

D. an imitation of the speech of adults

The problem of deciding at what point a baby’ imitations can be considered as speech _______.

A. is important because words have different meanings for different people

B. is not especially important because the changeover takes place gradually

C. is one that should be properly understood because the meaning of words changes with age

D. is one that should be completely ignored(忽略) because children’s use of words is of-ten meaningless

The speaker implies _______.

A. parents can never hope to teach their children new sounds

B. children no longer imitate people after they begin to speak

C. children who are good at imitating learn new words more quickly

D. even after they have learnt to speak, children still enjoy imitating

World Health Day is celebrated on 7 April to mark the anniversary of the founding of WHO in 1948. Each year a theme is selected for World Health Day that highlights a priority area of public health concern in the world. 
The theme for 2013 is high blood pressure. High blood pressure increases the risk of heart attacks, strokes(中風).

Who says Americans worship the almighty (全能的) dollar? It's not true. Having enough free time is more important to most Americans than being rich, according to a new survey.

Only 13 percent of more than 2,400 people questioned in the telephone survey ranked being wealthy as most important to them, while 67 percent ranked free time as their top priority (優(yōu)先考慮的事), higher than having a successful career, getting married, and having children. "Everyone wants free time to do the things they want to do, young, middle-aged or old," said Richard Morin, of the Pew Social ~ Demographic Trends Project, which conducted the survey. "So our desire to play unites us."

The survey also showed that people who were educated in university valued career success over wealth, so did middle-aged people. Not surprisingly, those who didn't have money, ranked wealth very highly. This included minorities, first generation Americans and less educated people. The survey also revealed that a disproportionate (不成比例的) number of people under the age of 30 and retired people in the group made $ 20,000 or less a year. But the emphasis on wealth lessens with age, with younger people putting value on it but hardly any seniors. "It just diminishes (減弱) with time as the reality sets in that you would never be rich," Morin said. "But also, as for old people the reality sets in that you don't have to be rich to lead a very comfortable and fulfilling life. "

While wealth was not at the top of people's list of priorities, 43 percent still said it was somewhat important.

1.The survey showed that the majority of American people ranked ______ as the most important.

A．wealth

B．a(chǎn) successful career

C．marriage

D．free time

2.Who cares least for wealth, according to the passage?

A．Young people

B．First generation Americans

C．Old people

D．Less-educated people

3. According to the survey, what did middle-aged people regard as more important?

A．success in career

B．education level

C．wealth

D．comfort

4. What is the belief of old people according to the third paragraph?

A．Wealth is as important to the old as health.

B．One needs to put money away for his retired life.

C．One doesn't have to be rich to live a satisfying life.

D．One would never get rich until he retires.

科目：高中英語 來源：20102011年山東省濰坊市三縣高一下期末聯(lián)考英語題 題型：閱讀理解

Most people think that the older you get, the harder it is to learn a new language. That is, they believe that children learn more easily and efficiently than adults. Thus, at some point in our lives, maybe around age 12 or 13, we lose the ability to learn languages well. Is this idea a fact or myth(懸念)？

Is it true that children learn a foreign language more efficiently than adults? On the contrary, research studies suggest that the opposite may be true. One report, on 2,000 Danish children studying Swedish, concluded that the teenagers learned more, in less time, than the younger children. Another report, on Americans learning Russian, showed a direct improvement of ability over the age range tested; that is, the ability to learn increased as the age increased, from childhood to adulthood.

There are several possible explanations for these findings. For one thing, adults know more about the world and therefore are able to understand meanings more easily than children. Moreover, adults can use logical(邏輯的) thinking to help themselves see patterns in the language. Finally, adults have more self-discipline (self-control) than children.

All in all, it seems that the common idea that children are better language learners than adults may not be a fact, but a myth.

1.The main idea of the passage is that         .

A．teenagers are more difficult to teach

B．Danish teenagers can learn Swedish faster than younger children

C．a(chǎn)dults are more logical than children

D．the ability to learn languages increases with age

2. If most people’s idea of learning languages is true, people may lose ability to learn languages well         .

A．a(chǎn)t an early age

B．when they reach their twenties

C．a(chǎn)t an old age

D．a(chǎn)fter they become young men

3.According to the passage, teenagers can learn a foreign language __________ than younger children.

A．harder

B．more efficiently

C．more slowly

D．more carefully

4.The reason why adults understand meanings more easily than children is that         .

A．a(chǎn)dults have more self-discipline

B．a(chǎn)dults like to play more than children

C．a(chǎn)dults have more knowledge than children

D．a(chǎn)dults accept new things more easily than children

5.The explanation for older student’s better achievement not mentioned in the above passage is that       .

A．a(chǎn)dults know more about the world.

B．a(chǎn)dults can use logical thinking

C．a(chǎn)dults have more self-discipline.

D．a(chǎn)dults can read better.
