【题目】【改编】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(激发,引起), and this depends on interaction between the mother and the child, where the mother recognizes the signals in the children’s babbling(咿呀声),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.

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 ?

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?

A. In a science report.

B. In an Entertainment magazine.

C. In a health report.

D. In a science fiction story.

【答案】

【1】C

【2】B

【3】D

【4】A

【5】A

【解析】

试题分析: 语言是否像食物一样是人类的一项基本需求,在生命关键的时候,没有它孩子就会饿死或者受到损害呢?实验表明这是有可能的。语言学家认为,语言在人一生中的各个阶段是按固定顺序发展的,如果错过这个关键时期,婴儿就不会轻松地学会语言了。

【1】C推理判断题。从文章第二段内容可知在实验中婴儿因缺少母爱和语言的交流而死去,由此判断这项实验是很残酷的,故选C。

【2】B细节理解题。根据文章第三段Most often the reason for this is that the mother is insensitive to the signals of the infant,可知语言发展滞后的孩子多数情况下是在语言习得最快的时期没有得到足够的语言输入,故选B。

【3】D细节理解题。根据第五段Recent evidence suggests that an infant is born with the capacity to speak.可知婴儿生来就有语言能力,故选D。

【4】A 推理判断题。本段内容介绍了语言敏感期的重要性,用鸟的例子来说明这一点,故选A。

【5】A 推理判断题。本文介绍了儿童时期语言的发展特点,由此判断属于科学类文章,故选A。

【题目】When 18thcentury scientists first came across Australias platypus (鸭嘴兽),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(哺乳动物).

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(针鼹鼠) 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 (鳄鱼),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.

C.Its the only poisonous mammal in the world.

D.It feeds its young on wild animal meat.

【2】Which of the following is NOT used as a comparison in the passage?

A.The crocodile.

B.The echidna.

C.The duck.

D.The dog.

【3】The characteristics of the platypus that have been described in the passage include________.

a.the color of its skin

b.the way it gets information

c.its walking pose

d.its strange appearance

A.b-c-d

B.a-b-c

C.a-c-d

D.a-b-d

【4】We can learn from the last paragraph that the platypus is________.

A.hunted for its meat

B.in danger of extinction

C.endangered because of air pollution

D.wellprotected now

【题目】阅读下面短文,按照句子结构的语法性和上下文连贯的要求,在空格处填入一个适当的词或用括号中词语的正确形式填空,并将答案填写在答题卡标号为1~10的位置上。

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."
