单选题It may look like just another playgroup，but a unique educational center in Manhattan is really giving babies something to talk about. "It's a school to teach languages to babies and young children with games, songs—some of the classes also have arts and crafts," said Francois Thibaut, the founder of the Langrage Workshop for Children, a place where babies become bilingual. Children as young as few months are exposed to French and Spanish before many of them can even speak English. Educators use special songs and visual (视觉) aids to ensure that when a child is ready to talk, the languages will not be so foreign. "Children have a unique capacity to learn many languages at the same time," said Thibaut. "Already at nine months, a child can tell the differences between the sounds he or she has heard since birth and the sounds he or she has never heard yet." Thibaut says the best time to expose children to language is from birth to 3 years old. For the last 30 years, the school has been using what it calls the Thibarut Technique, a system that combines language lessons with child's play. "I always wanted to learn Spanish, but by the time I got to high school it was too late to pick it up and speak fluently," said Marc Lazare, who enrolled his son at the school. "I figured at this age, two, it's a perfect time for him to learn." Aside from learning a language, the kids also gain a tremendous sense of confidence. One young student boasted that aside from French, she can speak five languages (though that included "monkey" and "lion"). The school gives children the tools to communicate, and sometimes that gives them an advantage over their parents. "I think they sometimes speak French when they think I won't understand them," said parent Foster Gibbons. Depending on the age group, classes run from 45 minutes up to 2 hours. Even when students are not in class, the program is designed to make sure the learning continues at home. Tapes and books are included, so kids can practice on their own.

单选题Being able to multitask is hailed by most people as a welcome skill, but not according to a recent study which claims that young people between the ages of eight and eighteen of the so-called Generation M are spending a considerable amount of their time in fruitless efforts as they multitask. It argues that, in fact, these young people are frittering (浪费) away as much as half of their time as they would if they performed the very same tasks one after the other. Some young people are using an ever larger number of electronic devices as they study. At the same time they are working, young adults are also surfing on the Internet, or sending out emails to their friends, and/or answering the telephone and listening to music on their iPods or on another computer. As some new device comes along, it is also added to the list rather than replacing one of the existing devices. Other research has indicated that this multitasking is even affecting the way families themselves function as young people are too wrapped up in (沉湎于) their own isolated worlds to interact with the other people around them. They can no longer greet family members when they enter the house nor can they eat at the family table. All this electronic wizardry (魔力) is supposedly also seriously affecting young people"s performance at university and in the workplace. When asked about their opinions of the impact of modern gadgets (小装置) on their performance of tasks, the great majority of young people gave a favorable response. The response from the academic and business worlds was not quite as positive. The former feel that multitasking with electronic gadgets by children affects later development of study skills, resulting in a decline in the quality of writing, for example, because of the lack of concentration on task completion. They feel that many undergraduates now urgently need remedial (补救的) help with study skills. Similarly, employers feel that young people entering the workforce need to be taught all over again, as they have become deskilled. While all this may be true, it must be borne in mind that more and more is expected of young people nowadays; in fact, too much praise rather than criticism is due in respect of the way today"s youth are able to cope despite what the older generation throw at them.
