[单项选择]第一篇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 U.S. 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 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 n

[单项选择]An industrial society, especially one as centralized and concentrated as that of Britain, is heavily dependent on certain essential services: for instance, electricity supply, water, rail and road transport, the harbors. The area of dependency has widened to include removing rubbish, hospital and ambulance services, and, as the economy develops, central computer and information services as well. If any of these services ceases to operate, the whole economic system is in danger.
It is this economic interdependency of the economic system which makes the power of trade unions (工会) such an important issue. Single trade unions have the ability to cut off many countries’ economic blood supply. This can happen more easily in Britain than in some other countries, in part because the labor force is highly organized. About 55 percent of British workers belong to unions, compared to under a quarter in the United States. For historical reasons, Britain’s unions have tended to develop

(62)The emergence of the hotel as a significant commercial institution, however, is a development of the past few centuries and may be traced by, example in the U.S.. The location of hotels has always been related to the transportation available. During colonial times hotels were usually situated in seaport towns, but by the end of the 18th century, when the coach had increased travel within the U.
