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 child. 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 out. 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 meaningless sound simply because he also uses it at other times 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,what is greatly different?________.

A. the amount of listening     

B. a number of listening

C. the sound of listening

D. the meaning of listening

starters are often long listeners, the sentence means one can ________.

A. be hard to speak fluently

B. begin to speak quickly

C. start with listening

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

these can not be said to show a baby’s intention to speak, these refer to  ________.

A. pain    B. happiness  C. Kindness   D. above of all

according to the writer, we can draw a conclusion that  ________.

A. children are fond of imitating

B. these imitation can be considered as speech

C. children get more experience of the world

D. children’s use  of  words are often meaningless

When a child is six months, he can  ________.

A. call his mama

B. imitate many languages

C. store new words

D. play with sounds

Dropouts for Ph. D. s

Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of Ph. D. s. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter of expert guessing. Last week a well-rounded study was published. It was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless.

The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph. D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates.

Discussing the study last week, Dr. Tucker said the project was initiated 'because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph. D. programs were capable of competing the requirement for the degree. Attrition at the Ph. D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of highly trained specialists and college teachers could be reduced by persuading the dropouts to return to graduate schools to complete the Ph. D.’

"The results of our research" Dr. Tucker concluded, "did not support these opinions."

1.    Lack of motivation was the principal reason for dropping out.

2.    Most dropouts went as far in their doctoral program as was consistent with their levels of ability or their specialties.

3.    Most dropouts are now engaged in work consistent with their education and motivation.

Nearly 75 per cent of the dropouts said there was no academic reason for their decision, but those who mentioned academic reason cited failure to pass the qualifying examination, uncompleted research and failure to pass language exams. Among the single most important personal reasons identified by dropouts for non-completion of their Ph. D. program, lack of finances was marked by 19 per cent.

As an indication of how well the dropouts were doing, a chart showed 2% in humanities were receiving $ 20,000 and more annually while none of the Ph. D. 's with that background reached this figure. The Ph. D. 's shone in the $ 7,500 to $ 15,000 bracket with 78% at that level against 50% for the dropouts. This may also be an indication of the fact that top salaries in the academic fields, where Ph. D. 's tend to rise to the highest salaries, are still lagging behind other fields.

As to the possibility of getting dropouts back on campus, the outlook was glum. The main condition which would have to prevail for at least 25 % of the dropouts who might consider returning to graduate school would be to guarantee that they would retain their present level of income and in some cases their present job.

The author states that many educators feel that            

[A] steps should be taken to get the dropouts back to campus.

[B] the dropouts should return to a lower quality school to continue their study.

[C] the Ph. D. holder is generally a better adjusted person than the dropout.

[D] The high dropouts rate is largely attributable to the lack of stimulation on the part of faculty members.

  Research has shown that          

[A] Dropouts are substantially below Ph. D. 's in financial attainment.

[B] the incentive factor is a minor one in regard to pursuing Ph. D. studies.

[C] The Ph. D. candidate is likely to change his field of specialization if he drops out.

[D] about one-third of those who start Ph. D. work do not complete the work to earn the degree.

  Meeting foreign language requirements for the Ph. D.

[A] is the most frequent reason for dropping out.

[B] is more difficult for the science candidate than for the humanities candidate.

[C] is an essential part of many Ph. D. programs.

[D] does not vary in difficulty among universities.

  After reading the article, one would refrain from concluding that          

[A] optimism reigns in regard to getting Ph. D. dropouts to return to their pursuit of the degree.

[B] a Ph. D. dropout, by and large, does not have what it takes to learn the degree.

[C] colleges and universities employ a substantial number of Ph. D. dropouts.

[D] Ph. D. 's are not earning what they deserve in nonacademic positions.

  It can be inferred that the high rate of dropouts lies in            

[A] salary for Ph. D. too low.

[B] academic requirement too high.

[C] salary for dropouts too high.

[D] 1000 positions.

The Galapagos a far-away archipelago(群岛) and largely untouched by man, is now facing a problem. Its local people, who live on the island of Santa Cruz, want to develop the business and tourist potential(旅游资源)of the island. Recently, they are locked in a bitter struggle with the naturalists who work at the Charles Darwin Centre, also on Santa Cruz. The naturalists want to protect the island’s wildlife which is already suffering as a result of human activity.

The animals’ great threat used to be sailors who, hundreds of years ago, robbed the islands for food. They wiped out about 250,000 Giant Tortoises. For example, on Pinta, one of the smallest islands, there are no Giant Tortoises left at all. The last survivor, an 80-year-old Giant Tortoise called Lonesome George, lives under the protection of naturalists at the Darwin Centre.

Today, the island’s animals are no longer hunted for food. But other dangers have replaced the threat from sailors. Goats, for example, introduced over the years by man, have gone wild. With no natural enemies, their number has reached 10,000 on the largest of the Galapagos islands, Isabella. They are eating huge quantities of plants, and robbed the remaining Giant Tortoises of food. The problem is now so bad that the National Park Service has hired hunters to kill the goats in order to save the Giant Tortoise from dying out.

Today, you can find the Giant Tortoises on the island of _______.

A. Santa Cruz           B. Pinta             C. Isabella           D. Galapagos

Which of the following shows the right relationship between the Galapagos, Isabella, Pinta and Santa Cruz?

A. The Galapagos>Pinta>Isabella>Santa Cruz         

B. Isabella>Santa Cruz>the Galapagos>Pinta

C. The Galapagos>Isabella>Santa Cruz>Pinta         

D. Isabella>the Galapagos>Pinta>Santa Cruz

We can learn from the article the greatest danger to the Giant Tortoises is from________.

A. sailors         B. hunters            C. goats            D. the local people

From the first paragraph we can infer that _____.

A. the naturalists try to help the local people with their interest.

B. The local people pay more attention to the economic growth than the wildlife there,

C. The animals and plants are of great importance to the local.

D. The naturalists don’t care about the local people at all
