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 our teeth into. 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 __________.

Energy independencehas a nice ring to it.Doesn't it? If you think so,you're not alone,because energy independence has been the dream of American president for decades,and never more so than in the past few years,when the most recent oil price shock has been partly responsible for kicking off the great recession.
“Energy independence”and its rhetorical (修辞的) companion“energy security” are,however,slippery concepts that are rarely though through.What is it we want independence from,exactly?
Most people would probably say that they want to be independent from imported oil.But there are reasons that we buy all that old from elsewhere.
The first reason is that we need it to keep our economy running.Yes,there is a trickle(涓涓细流)of biofuel(生物燃料)available,and more may become available,but most biofuels cause economic waste and environmental destruction.
Second,Americans have basically decided that they don't really want to produce all their own oil.They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection.To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?
Third,there are benefits to trade.It allows for economic efficiency,and when we buy things from places that have lower production costs than we do,we benefit.And although you don't read about this much,the United States is also a large exporter of oil products,selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and,in fact,relies on that steady flow to maintain its economy.When that flow is interrupted,we feel the pain in short supplies and higher prices.At the same time,we obtain massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.What does the author say about energy independence for America?
A.It sounds very attractive. |
B.It ensures national security. |
C.It will bring oil prices down |
D.It has long been everyone’s dream. |
Why does America rely heavily on oil imports?
A. It wants to expand its storage of crude oil(原油).
B. Its own oil reserves are quickly running out.
C. It wants to keep its own environment undamaged.
D. Its own oil production falls short of demanD.What does the author say about oil trade?
A.It proves profitable to both sides. |
B.It improves economic efficiency. |
C.It makes for economic prosperity. |
D.It saves the cost of oil exploration. |
Chimpanzees,long considered reluctant to share,apparently can display selfless tendencies,revealing one more key way our closest living relatives are like humans,scientists find. These findings could shed light on the evolution of altruism in humans.
Previously,a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago.In recent years,however,research has revealed just how much chimpanzees have in common with us.They can hunt with spears,play with dolls and mourn their partners'death.
“Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others,often so complicated that the experiments tested tool skills rather than social tendencies,”De Waal told Live Science.“Ours is the first study that uses no such implement at all.”
In addition to using complex food-delivery systems,past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others.In these new,simplified experiments,two apes were housed next to each other with a screen through which they could see each other.Then,one chimpanzee had to choose between two differently colored tokens (币) from a bin,one of which represented a pro-social (亲社会的) option,the other a selfish option.The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper.The selfish option only rewarded the ape who made the choice.
In a study with seven adult female chimps placed into various pairs,the scientists found all the apes showed a definite preference for the pro-social option.“For me,the most important finding is that like us,chimpanzees take into account the needs and wishes of others,”researcher Victoria Horner,said.
The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves.They were less likely to reward partners who pressured through making a fuss,begging persistently or spitting water at them.This is opposite to a long-standing view that the chimpanzees only share food under pressure.The word“ altruism” (paragraph 1) is closest in meaning to ______.
A.selfishness |
B.selflessness |
C.willingness |
D.reluctance |
Recent researches are performed with less complicated implements mainly to ______.
A.show that chimps are only good at using implements |
B.see whether chimps are willing to share food with others |
C.find out if chimps are likely to reward partners |
D.test chimps’ social tendencies instead of tool skills |
Which of the following might be the best title of the passage?
A.Evolution History of Altruism in Humans |
B.Similarities between Chimps and Mankind |
C.Chimps Do Show Selfless Behavior |
D.Chimps Only Share Food under Pressure |

Have you ever used Facebook? Many people are being lured (引诱) onto it with the promise of a fun,free service without realizing they're paying for it by giving up large amounts of personal information.Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don't realize this is happening.Even if they know what the company is up to,they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.
The biggest problem,however,is that the company keeps changing the rules.Early on,you keep everything private.That was the great thing about Facebook — you could create your own little private network.Last year,the company changed its privacy rules so that many things — your city,your photo,your friends' names—were set,by default (默认) to be shared with everyone on the Internet.
According to Facebook's vice-president Elliot Schrage,the company is simply making changes to improve its service,and if people don't share information,they have a “less satisfying experience”.
Some critics think this is more about Facebook looking to make more money.Its original business model,which involved selling ads and putting them at the side of the page,totally failed.Who wants to look at ads when they're online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington.In April,Senator(议员) Charles Schumer called on Facebook to change its privacy policy.He also urged the Federal Trade Commission to set guidelines for social-networking sites.“I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,”Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy is only the beginning,which is why I'm considering deactivating(撤销) my account.Facebook is a handy site,but I'm upset by the idea that my information is in the hands of people I don't know.That's too high a price to pay.What do we learn about Facebook from the first paragraph?
A.It is a website that sends messages to targeted users. |
B.It makes money by putting on advertisements. |
C.It profits by selling its users'personal data. |
D.It provides loads of information to its users. |

D.They care very little about their personal information. |
Why does Facebook make changes to its rules according to Elliot Schrage?
A.To provide better service to its users. |
B.To follow the Federal guidelines. |
C.To improve its users'connectivity. |
D.To expand its scope of business. |
Why does the author plan to cancel his Facebook account?
A.He is dissatisfied with its current service. |
B.He finds many of its users untrustworthy. |
C.He doesn't want his personal data abused. |
D.He is upset by its frequent rule changes. |
When Kate's paintings were on show in London,a poet described her paintings as “a ribbon (丝带)around a bomb”.Such comments seem to suggest Kate had a big influence on the art world of her time.Sadly,she is actually a much bigger name today than she was during her time.
Born in 1907 in a village near Mexico City,Kate suffered from polio(小儿麻痹症)at the age of seven.Her spine (脊柱)became bent as she grew older.Then,in 1925,her back was broken in several places in a school-bus accident.Throughout the rest of her life,the artist had many operations,but nothing was able to cure the terrible pain in her back.However,the accident had an unexpected side effect.While lying in her bed recovering,Kate taught herself to paint.
In 1929,she got married to Diego Rivera,another famous Mexican artist.Rivera's strong influences on Kate's style can be seen in her early works,but her later works from the 1940s,known today as her best works,show less influence from her husband.
Unfortunately,her works did not attract much attention in the 1930s and1940s,even in her home country.Her first one-woman show in Mexico was not held until 1953.For more than a decade after her death in 1954,Kate's works remained largely unnoticed by the world,but in the 1970s her works began to gain international fame at last.What does the underlined phrase “a much bigger name” in paragraph 1 most probablymean?
A.A far better artist. |
B.A far more gifted artist. |
C.A much stronger person. |
