单选题Step Back in Time Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for US and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don"t slip back into bad habits, let"s have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn"t live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn"t have fridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight 1o earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks (火柴杆) (a job done by many children) or working with your dad by now.

单选题 Why Don't Babies Talk Like Adults? Over the past half century, scientists have settled on two reasonable theories related to baby talk. 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 factor. 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 US each year. Many of them no longer hear their birth language after they arrive, and they must learn English more or less the same way infants do—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 combing words in sentences when their vocabulary reached the same sizes, further suggesting that what matter is not how old you are or how mature your brain is, but the number of words you know. This finding—that having more mature brains did not help the adoptees avoid the toddler-talk stage—suggests that babies speak in baby talk 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 acheive 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.

单选题Communications Revolution Cyberspace, data superhighway, multi-media—for those who have seen the future, the linking of computers, television and telephones will change our lives forever. Yet for all the talk of a forthcoming technological utopia little attention has been given to the implications of these developments for the poor. As with all new high technology, while the West concerns itself with the "how", the question of "for whom" is put aside once again. Economists are only now realizing the full extent to which the communications revolution has affected the world economy, Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade, exchange and interest rates and money movements are more important than the production of goods. The electronic economy made possible by information technology allows the haves to increase their control on global markets—with destructive impact on the have-nots. For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies. So what are the options for regaining control? One alternative is for developing countries to buy in the latest computers and telecommunications themselves—so-called "development communications" modernization. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries" economies. Communications technology is generally exported from the U.S., Europe or Japan l the patents, skills and ability to manufacture remain in the hands of a few industrialized countries. It is also expensive, and imported products and services must therefore be bought on credit—credit usually provided by the very countries whose companies stand to gain. Furthermore, when new technology is introduced there is often too low a level of expertise to exploit it for native development. This means that while local elites, foreign communities and subsidiaries of transnational corporations may benefit, those whose lives depend on access to the information are denied by it.
