The most intensive period of speech and language development for humans is during the first three years of life, a period when the brain is developing and maturing. These skills appear to develop best in a world that is rich with sounds, sights, and consistent(一致的,协调的,相容的)exposure(揭发)to the speech and language of others.

There is increasing evidence suggesting that there are "critical periods" for speech and language development in infants and young children. This means that the developing brain is best able to absorb a language, any language, during this period. The beginning signs of communication occur during the first few days of life when an infant learns that a cry will bring food, comfort, and companionship.  As they grow, infants begin to sort out the speech sounds (phonemes) or building blocks that compose the words of their language. Research has shown that by six months of age, most children recognize the basic sounds of their native language

 As the speech mechanism (jaw, lips, and tongue) and voice mature, an infant is able to make controlled sound. By six months of age, an infant usually babbles or produces repetitive syllables such as "ba, ba, ba" or "da, da, da." By the end of their first year, most children have mastered the ability to say a few simple words. Children are most likely unaware of the meaning of their first words, but soon learn the power of those words as others respond to them.

By eighteen months of age, most children can say eight to ten words. By age two, most are putting words together in crude sentences such as "more milk." During this period, children rapidly learn that words symbolize or represent objects, actions, and thoughts. At this age they also engage in representational or pretend play. At ages three, four, and five, a child's vocabulary rapidly increases, and he or she begins to master the rules of language.

1.According to the passage, which of the statements is NOT true

    A.The developing brain is best able to absorb any language.

2.We can infer from the passage that____

    A.by six months of age, an infant must babble or produce repetitive syllables

    B.by their first year, most children are most likely aware of the meaning of their first words

    C.by 2, children rapidly learn that words symbolize or represent objects, actions, and thoughts

    D.the brain development is critical to develop children’s speech and language ability

3.That there are “critical periods” for speech and language development in infants and young children means ______

    A.that children are so young that it is easy for them to study

    B.that the developing brain is best able to absorb a language, any language

    C.that the children are eager to learn the language

B
A new study suggests that the more teenagers watch television , the more likely they are to develop depression (抑郁)as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered.
The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression . They based their findings on more than four thousand adolescents who were not depressed when the survey began in 1995.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio.
Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.
Seven years later, in 2002, more than seven percent of the young people had signs of depression. Their average age at that time was twenty-one.
Brian Primack at the Universtiy of Pittsburgh Medical School was the leading author of the new study . He said every extra hour of television meant an eight percent increase in the chances of developing signs of depression.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
Doctor Primack says the study did not explore if watching TV causes depression . But one possibility, like sports and socializing. It might also interfere with sleep, he says, and that could have an influence.
The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.
60.The average age of the depressed young people should be_______when they began to receive the survey.
A.21           B.15              C.14                D.20
61.According to the passage, which of the following can possibly lead to depression?
A.Swimming                           B.Attending a party
C.Attending religious services             D.Watching TV for a long time.
62.We can learn from the passage_______.
A.the survey lasted a short time
B.over 280 teenagers who received the survey became more or less depressed in 2002
C.men are more likely to become depressed than women
D.the study about the relationship between media use and depression was published in the journal Social Indicators Research
63.What is the best title for the passage?
A.Teens, television, depression
B.Depression—the common problem of teens
C.Problems of watching TV
D.Teens—a group enjoying watching TV

B
A sunflower is a sunflower. A mobile phone is a mobile phone. But can combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower.
A biodegradable (生物所能分解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and is able to change shape. Over time it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into wastes, it forms fertilizers. These feed the seed and help the flower grow.
Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grown when the phone is thrown away. “We’ve only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.
As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means manufacturers are under pressure to fine ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists.
“The seed comes out and the flower grows in the pot so you don’t have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.
61. What is the purpose of this passage?
A. Tell the popularity of biodegradable cell phone.
B. To persuade the reader to buy the biodegradable cell phone.
C. To discuss the development of phone technology.
D. To introduce an environmental-friendly cell phone to readers.
62. People throw away their cell phones most probably because _________.
A. there is something wrong with them   B. no sunflowers can grow out of them
C. they are out of fashion              D. they are becoming cheaper and cheaper
63. It could be learned from the passage that __________.
A. developing the new type of phone is mainly to protect the environment
B. phone-makers will benefit much more from the new type of phone
C. the new type of phone will certainly be popular with users all over the world
D. the phones that can be recycled are available only in Britain now
64. According to the passage, which of the following statements is right?
A. The new material for the biodegradable phone was found by British scientists.
B. The cover of the new type of mobile can bread down and become fertilizers after it becomes waste.
C. The sunflower seed in the best to be put into the phone cover.
D. The biodegradable cover must be very expensive.
65. What might be the most suitable title for this passage?
A. Sunflower and Phone.        B. Plant Your Phone.
C. Protect Our Environment.     D. No Worry about Phone.
