【題目】【改編】Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the experiment of Frederick in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.

All the infants died before the first year. But clearly there was more than lack of language here. What was missing was mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected.

Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly at the right time, but the process is slow and hard once the critical stage has passed.

Experts suggest that speech stages are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months they can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to five words. At three he knows about 1,000 words, which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar.

Recent evidence suggests that an infant is born with the capacity to speak. What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern “toy bear”. And even more incredible is the young brain’s ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.

But speech has to be induced(激發(fā),引起), and this depends on interaction between the mother and the child, where the mother recognizes the signals in the children’s babbling(咿呀聲),grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s nonverbal signals is essential to the growth and development of language.

【1】The experiment of Frederick proved ____.

A. lack of mothering didnt affect the development of a baby

B. only lack of language could kill a baby

C. very cruel to the babies in the experiment

D. babies could be starved to death

【2】Why are some children backward in speaking?

A. Because they are born disabled.

B. Because they lack language input when in sensitive periods.

C. Because they are exposed to too much language at once.

D. Because their mothers are not smart enough

【3】Which of the following is true ?

A. If a child starts to speak later than others, he will be backward in future.

B. If the ideal time for acquiring skills passes, there will be a second time.

C. A child can only imitate others language.

D. An infant is born with the ability to speak.

【4】What is the purpose of the example of birds in the third paragraph?

A. To prove the importance of the sensitive periods.

B. To prove birds has the same ability to speak as human.

C. To explain why some birds cant sing.

D. To inform the results of Frederick’s experiment.

【5】where can you read this passage?

C. In a health report.

D. In a science fiction story.

【答案】

【1】C

【2】B

【解析】

試題分析: 語言是否像食物一樣是人類的一項基本需求,在生命關鍵的時候,沒有它孩子就會餓死或者受到損害呢?實驗表明這是有可能的。語言學家認為,語言在人一生中的各個階段是按固定順序發(fā)展的,如果錯過這個關鍵時期,嬰兒就不會輕松地學會語言了。

【1】C推理判斷題。從文章第二段內容可知在實驗中嬰兒因缺少母愛和語言的交流而死去,由此判斷這項實驗是很殘酷的,故選C。

【2】B細節(jié)理解題。根據(jù)文章第三段Most often the reason for this is that the mother is insensitive to the signals of the infant,可知語言發(fā)展滯后的孩子多數(shù)情況下是在語言習得最快的時期沒有得到足夠的語言輸入,故選B。

【3】D細節(jié)理解題。根據(jù)第五段Recent evidence suggests that an infant is born with the capacity to speak.可知嬰兒生來就有語言能力,故選D。

【4】A 推理判斷題。本段內容介紹了語言敏感期的重要性,用鳥的例子來說明這一點,故選A。

【5】A 推理判斷題。本文介紹了兒童時期語言的發(fā)展特點,由此判斷屬于科學類文章,故選A。

【題目】When 18thcentury scientists first came across Australias platypus (鴨嘴獸),they thought it was a trick.It is not surprising that the platypus made people confused.This funnylooking animal has feet and is a kind of warmblooded mammal(哺乳動物).

While other mammals usually keep their blood at around 37 degrees,the platypus has a lower body temperature of 32 degrees.As to its appearance,the platypus mouth is not really like the ducks; its mouth actually looks a bit softer.The platypus closes its eyes when swimming instead of watching its hunters.It uses its mouth to pick up outside information made by the creatures underwater.

Strangest of all,the platypus is a mammal that can lay eggs.And there is only one other kind of mammal that can lay eggs,the echidna(針鼴鼠) of Australia.Both the platypus and the echidna lay soft shelled eggs,and both feed their young with their own milk that comes out of their skin.These animals also walk in a way that is similar to crocodiles (鱷魚),with legs on the sides of their bodies rather than under them.

Though pretty in a special way,the platypus is actually one of the few mammals that are poisonous.A male platypus has knifelike bones on its back legs which have enough poison to kill a dog.

The platypus has the honor of being one of the oldest mammals in the world.Until the early 20thcentury,it was hunted for its fur,but it is now protected.Although the platypus is easily influenced by pollution,it is not under any immediate threat.

【1】What can we learn about he platypus?

A.It has a lower body temperature than other mammals.

B.It only closes its eyes when underwater.

A.b-c-d

B.a(chǎn)-b-c

D.a(chǎn)-b-d

Scientists have discovered that __【1】____(stay) in the cold could help us lose weight. Researchers at the University of California found that exposure to the cold increases levels of a protein that helps form brown fat -------- the type of fat that produces heat and keeps us warm. Brown fat burns energy, ___2____ helps us lose weight. White fat stores extra energy, which results __3____ weight gain. The researchers said that because air conditioning and heating give us constant, ___4____ (comfort) temperatures, our body's need for brown fat has decreased. They found that: "Outdoor workers in northern Finland who __5____ (expose) to cold temperature have __6____ significant amount of brown fat when ___7___ (compare) to same-aged indoor workers."

The research was conducted on two different control groups of mice. __8____ group was injected with the protein that helps create brown fat. This group later gained 30% less weight after both groups were fed high-fat diets. The researchers say this could be good news in the fight against obesity. People who are obese have ___9____(low) levels of brown fat than thinner people. Head researcher Hei Sook Sul said: "This protein could become an important target for research into the treatment and prevention of obesity and obesity-related diseases." She added: "If you can somehow increase levels of this protein, you could __【10____ (possible) lose more weight even if eating the same amount of food."
