How Babies Learn Language　　During the first year of a child’s life, parents and careers are concerned with its physical development very carefully. It is interesting just how easily children learn language. Children who are just three or four years old, who cannot yet tie their shoelaces, are able to speak in full sentences without any specific language training.　　The current view of child language development is that it is an instinct—something as natural as eating or sleeping. According to experts in this area, this language instinct is innate—something each of us is born with. But this prevailing view has not always enjoyed widespread acceptance.　　In the middle of last century, experts of the time, including a renowned professor at Harvard University in the United States, regarded child language development as the process of learning through mere repetition. Language “habits” developed as young children were they used incorrect forms of language correctly and ignored or punished when they used incorrect forms of language. Over time, a child, according to this theory, would learn language much like a dog might learn to behave properly through training.　　Yet even though the modern view holds that language is instinctive, experts like Assistant Professor Lise Eliot are convinced that the interaction a child has with its parents and caregivers is crucial to its developments. The language of the parents and caregivers is so important that the child will learn to speak in a manner very similar to the model speakers it hears.Given that the models parents provide are so important, it is interesting to consider the role of “baby talk” in the child’s language development. Baby talk is the language produced by an adult speaker who is trying to exaggerate certain aspects of the language to capture the attention of a young baby.　　Dr Roberta Golinkoff believes that babies benefit from baby talk. Experiment show that immediately after birth babies respond more to infant-directed talk than they do to adult-directed talk. When using baby talk, people exaggerate their facial expressions, which helps the baby to begin to understand what is being communicated. She also notes that the exaggerated nature and repetition of baby talk helps infants to learn the difference between sounds. Since babies have a great deal of information to process, baby talk helps. Although there is concern that baby talk may persist too long, Dr Golinkoff says that it stops being used as the child gets older, that is, when the child is better able to communicate with the parents.　　Professor Jusczyk has made a particular study of babies’ ability to recognize sounds, and says they recognize the sound of their own names as early as four and a half months. Babies know the meaning of Mummy and Daddy by about six months, which is earlier than was previously believed. By about nine months, babies begin recognizing frequent patterns in language. A baby will listen longer to the sounds that occur frequently, so it is good to frequently call the infant by its name.　　An experiment at Johns Hopkins University in USA, in which researchers went to the homes of 16 nine-month-olds, confirms this view. The researchers arranged their visits for ten days out of a two-week period. During each visit the researcher played an audio tape that included the same three stories. The stories included odd words such as “python” or “hornbill”, words that were unlikely to be encountered in the babies’ everyday experience. After a couple of weeks during which nothing was done, the babies were brought to the research lab, where they listened to two recorded lists of words. The first list included words heard in the story. The second included similar words, but not the exact ones that were used in the stories.　　Jusczyk found the babies listened longer to the words that had appeared in the stories, which indicated that the babies had extracted individual words from the story. When a control group of 16 nine-month-olds, who had not heard the stories, listened to the two groups of words, they showed no preference for either list.　　This does not mean that the babies actually understand the meanings of the words, just the sound patterns. It supports the idea that people are born to speak, and have the capacity to learn language from the day they are born. This ability is enhanced if they are involved in conversation. And, significantly, Dr Eliot reminds parents that babies and toddlers need to feel they are communicating.　　Do the following statements agree with the views of the writer in the passage “How babies learn language”?　　YES if the statement agrees with the information　　NO　　　　　　　　if the statement dose not agree with the information　　NOT GIVEN　　　　if there is no information about this in the passage　　1．From the time of their birth humans seem to have an ability to learn language.　　2．According to experts in the 1950s and 1960s, language learning is very similar to the training of animals.　　3．Repetition in language learning is important, according to Dr Eliot.　　4．Dr Golinkoff is concerned that “baby talk” is spoken too much by some parents.　　5．The first word a child learns to recognize is usually “Mummy” or “Daddy”.
参考答案和解析
正确答案：
1.Y 从第二段The current view of child language development…something each of us is born with可知人类学习语言的能力是与生俱来的。
2.Y 从第三段最后a child…would learn language much like a dog might learn to behave properly through training可知20世纪中叶的专家们认为人类学习语言就像训练狗之类的动物一样,通过重复就能实现。
3.NG 第四段开头提出Eliot are convinced that the interaction a child has with its parents and caregivers is crucial to its developments,只说明Eliot认为孩子与父母等人的互动对其发展很重要,并未涉及重复在学习语言中是否重要。
4.N 第六段中Dr Roberta Golinkoff believes that babies benefit from baby talk,阐述了Dr Golinkoff对baby talk的观点。她认为baby talk对孩子的成长很有好处,而不是说家长对此过分强调。
5.N 第七段中Professor Jusczyk研究发现婴儿四个半月时就能识别自己的名字,大约六个月时便知道“父亲”“母亲”的含义,九个月时开始识别常用的语言形式。可知孩子最早的识别的应该是自己的名字。

第1题：

Parents can have a great impact on the development of their children's creativity in art. But first，they have to know how. They may find the following advice interesting and instructive.

Encourage free drawing rather than coloring books. Coloring books stop the possibility of self-expression. A child may just enjoy colorful pictures and never learn how to express himself. As an art teacher says，“Children have a very powerful instinct to draw freely and roughly. Such practice makes them learn language easily. ”In fact，a child expresses himself in rough drawing. This is the beginning of literacy and creativity. Also，parents should not teach their kids“how”to draw and they should not make their kids draw realistic pictures to entertain themselves. Experience tells us that such teaching from the parents will discourage children，making them think they can't do it the “right”way.

Competition and rewards should also be avoided in the process of artistic creation. A child's natural instinct to create will disappear if he or she thinks about prize while drawing.

Parents should be role models for their kids. They should not say things like，“I can't draw a straight line. ”Instead，they should learn to say，“I love to create. ”This teaches children that the process of creation is more important than the product. If children see their parents drawing，cooking or building creatively，they will do the same.

Buy a notebook for your child to use every day. This can be a journal for making up stories，writing ideas and drawing pictures. Even the youngest child can use it to draw freely and roughly，expressing himself.

Take your child to places that promote ideas and creativity. Art museums，science centers，libraries and children's museums all are great places to see other people's creativity. That will inspire children to make their own creations and inventions.

Give children choices and free time. Some of the best ideas come from daydreaming and imagining.

In short，parents should allow their kids to have the freedom to invent for themselves. That means not always teaching and commanding.

To develop their artistic creativity，children should be encouraged to______.

A．draw freely and roughly

B．learn to draw realistic pictures

C．know how to draw before they start

D．learn to draw good pictures to get prizes


正确答案：A
解析：推理判断题。由第二段第一句可知：应该鼓励孩子们自由地画画而不应该鼓励他们看彩色书。且由第二段第四句可知：孩子们的自由，随意画画的能力很强。因此，A项符合题意。

Why Don ' t Babies Talk Like Adults?

Over the past half-century,scientists have settled on two reasonable theories related to babytalk.One
states that a young child's brain needs time to master language,in the same way that it does to master other
abilities such as physical movement. The second theory states that a child's vocabulary level is the key fac-
tor. According to this theory,some key steps have to occur in a logical sequence before sentence formation
occurs.Children's mathematical knowledge develops in the same way.
In 2007,researchers at Harvard University,who were studying the two theories,found a clever way to
test them.More than 20,000 internationally adopted children enter the U.S.each year. Many of them no lon-
ger hear their birth language after they arrive,and they must learn English more or less the same way infants
do一that is,by listening and by trial and error. International adoptees don't take classes or use a dictionary
when they are learning their new tongue and most of them don't have a well-developed first language.All of
these factors make them an ideal population in which to test these competing hypotheses about how language
is learned.
Neuroscientists Jesse Snedeker,Joy Geren and Carissa Shafto studied the language development of 27
children adopted from China between the ages of two and five years.These children began learning English
at an older age than US natives and had more mature brains with which to tackle the task.Even so,just as
with American-born infants,their first English sentences consisted of single words and were largely bereft（缺
乏的）of function words , word endings and verbs. The adoptees then went through the same stages as typical
American-born children,though at a faster clip.The adoptees and native children started combining words in
sentences when their vocabulary reached the same sizes,further suggesting that what matters is not how old
you are or how mature your brain is,but the number of words you know.
This finding一that having more mature brains did not help the adoptees avoid the toddler-talk stage一
suggests that babies speak in babytalk not because they have baby brains,but because they have only just
started learning and need time to gain enough vocabulary to be able to expand their conversations.Before
long,the one-word stage will give way to the two-word stage and so on. Learning how to chat like an adult is
a gradual process.
But this potential answer also raises an even older and more difficult question.Adult immigrants who
learn a second language rarely achieve the same proficiency in a foreign language as the average child raised
as a native speaker. Researchers have long suspected there is a"critical period"for language development,
after which it cannot proceed with full success to fluency.Yet we still do not understand this critical period or
know why it ends.

Snedeker,Geren and Shafto based their study on children who________.
A:were finding it difficult to learn English
B:were learning English at a later age than US children
C:had come from a number of language backgrounds
D:had taken English lessons in China

答案：B
解析：
本题是推理判断题。第二段意思是：通过把被收养的国际儿童作为实验对象，采取不 同的培训方法来解释儿童语言习得的特殊途径。故选D。
由文章第三段第二句话可知这些儿童开始学习英语时要比美国本土学说话的孩子年龄大。
由文章第三段后半部分可知，与美国本土唯呀学语的儿童相比，被收养的中国儿童的 语言发展在其最初开口所说的单词，学习语言的方法和开始造句的阶段都相同。由该段倒数 第二句话“The adoptees then went through the same stages as typical American-born children, though at a faster clip.”该句中at a faster clip意思是“以更快的速度”。由此可知他们学习语言 的速度比本土的孩子快。故选A。
文章第四段讲述了哈佛大学研究人员的实验结果表明儿童说话时只能使用儿童话语 是因为他们需要时间来获得更多的词汇从而扩展对话形式。而从儿童话语过渡到成人话语形 式是一个渐进的过程。从最后两句话“Before long , the one-word stage will give way to the two-word stage and so on.Learning how to chat like an adult is a gradual process.”可以看出选C。
由文章最后一段倒数第二句话“Researchers have long suspected there is a ' critical period ' for language development , after which it cannot proceed with full success to fluency.”可知 研究者猜想在人的语言发展过程中有一“关键期”，过了这一“关键期”，人的语言发展就不可 能达到流利的程度。故选C。

One-third of Parents Lack Facts about Child Development
One-third of parents of babies have a surprisingly low knowledge of child development,in-cluding basic concepts about what their children should know or how they should act,a new study finds.
For instance,the study found that many parents don't know that 1 -year-olds can't tell the difference between right and wrong,and often don't cooperate or share when playing with other children.
The results are surprising because the parents who took part in the survey had young chil- dren,said lead author Dr. Heather Paradis,a pediatric fellow at the University of Rochester Med-ical Center in New York.“They were watching or had just watched their kids go through this de-velopment,and they were probably the most knowledgeable of anybody.”
Paradis and her colleagues examined the results of a survey of parents—98 .6 percent of whom were mothers—of more than 10,000 9-month-old babies. As part of the survey,the parents were asked 1 1 questions designed to test their knowledge of a baby's development.
The researchers also examined what the parents said about their interactions with their chil- dren,and watched videotapes of how the parents taught new things to their kids.One-third of those surveyed incorrectly answered four or more of the questions.Even when the researchers ad-justed the statistics to account for such factors as education levels and income,those parents were still less likely to enjoy“healthy interactions”with their children.
A lack of proper understanding of a child's development can cause assorted problems,Para-dis said. For example,she said,a mother might expect an 18-month-old child to sit still for a doctor's appointment,even though children that age are normally curious and like to wander around.
“A mom could misinterpret a child's normal curiosity as intentionally being defiant,and could respond with harsh discipline,withdrawal of affection and repetition of that pattern over time,”Paradis said.“That could hinder the child's potential for full growth and development.”
The findings were to be presented Sunday at the Pediatric Academic Societies' meeting in Honolulu.
One solution,Paradis said,is for pediatricians to take a more active role in educating new parents.“By improving knowledge of child development among all parents,not just those who are at highest risk,there's an opportunity to enhance parent-child interaction,”she said.“It can ul-timately lead to better parenting.”

Most American families are nuclear rather than extended ones.
