Article: If you want to help children develop language and speech skills, UCLA researchers say, listening to what they have to say is just as important as talking to them. The effect of a conversation between a child and an adult is about six times as great as the effect of adult speech input alone, the researchers found. "Adults speaking to children helps language develop, but what matters much more is the interaction," said the study' s lead author, Frederick Zimmerman, an associate professor in the School of Public Health at the University of California, Los Angeles. The researchers also found that TV viewing didn' t have much of an effect -- positively or negatively -- as long as it wasn' t displacing conversations between an adult and a child. The UCLA study included 275 families with children between 2 months and 48 months old. They represented a variety of incomes and education. The researchers found that, in an average day, children hear about 13,000 spoken words from adults and participated in about 400 adultchild conversations a day. Assessed separately, factors positively associated with language development included each additional 100 conversations a day and each 1,000 word increase in the number of words spoken by adults and heard by children. When looked at alone, TV was negatively associated with language development. But, when the three factors were analyzed together, the only one that stood out was conversation between adults and children. "The more a child speaks and interacts with an adult, the better idea a parent has about where the child is," Zimmerman said. "Although it' s mostly done unconsciously, parents will provide feedback and correct mistakes. They'll also _ their speech to the child. Parents can give a child words by talking to them about what they' re doing, such as, 'I'm putting on your pajamas now'. But give your child the opportunity to talk, hopefully without the rest of the noise in the environment," she added. "If parents can carve out some conversation time -- maybe at bath...

Options: A: Talk with kids, not at them B: Let your children voice their own opinions C: How to develop a child' s language ability D: The importance of early child language development

However, we will try to introduce you to some of the more important cultural differences. Personal Space When two people are talking to each other, they tend to stand a distance apart. Each person has an invisible boundary around their body into which other people may not come. Interestingly,the average personal distance varies from culture to culture. Americans tend to require more personal space than in other cultures. So if you try to get too close to an American during your conversation, he or she will feel that you are "in their face" and will try to back away. Try to avoid physical contact while you are speaking, since this may also lead to _ . Tipping Restaurants do not include a service charge in the bill, so you should tip the waiter 15% of the total bill. If service is slow or particular bad, some Americans will tip only 10%. If service is particularly good, it is appropriate to tip 20%. If service is so bad that you will never eat in the restaurant again, leave two cents. It tells the waiter that you haven't forgotten to leave a tip. Tipping is only appropriate in restaurants which offer table service. You do not tip the cashier in a fast food restaurant. Gestures To wave goodbye or hello to someone, raise your hand and wave it from side to side, not front to back. Wave the whole hand, not just the fingers. Waving the hand front to back or the fingers up and down means "no", "stop", or "go away'. Holding your hand up with the palm facing forward but no movement means "stop". If you want to point at an object, extend the index finger and use it to point at the object. It is not polite to point at people. Although showing your fist with the thumb up or your open hand with the tips of the thumb and index finger together forming an "O" means "OK", these are stereotypes . Americans understand these gestures, but they are mainly used by actors in movies, not in real life. Question: We can learn from the passage that in the US _ . Options: A: it's natural to touch each other in a conversation. B: it's polite to leave a tip though the service is bad. C: there is only one gesture meaning "stop". D: Americans use the same gesture to point at people and objects.

A report by the Bank of Scotland interviewed over 1,000 young people in Britain and found that 77% get pocket money. Different families give different amounts of pocket money. The average for eight-to-fifteen-year-olds in the UK is about PS6 a week. Children in Scotland receive slightly more than the national average and Londoners get the most. Teenagers, logically, get more money than younger children. Some fifteen-to-nineteen-year-olds receive more than PS100 a month. The report found that many children save at least a quarter of their weekly pocket money and that more boys than girls save their money. Lots of young people have to do housework to get their pocket money. They help at home with jobs like cleaning and cooking. A part-time job is a choice for teenagers who don't have pocket money or who want to earn extra money. About 15% of teenagers have a job. Popular part-time jobs for teenagers include delivering newspapers, shop work, and working in a restaurant or cafe. There are strict government laws about working hours. Only children over 13 can work (there are some exceptions, for example, for actors.) On a school day they can work a maximum of 2 hours a day but not during school hours. At weekends and during school holidays they can work longer hours. The national minimum wage for people aged 16-17 is PS3.57 per hour. 18-year-olds must earn a minimum of PS4.83. There isn't a national minimum waged for people under 16. In Britain some children and teenagers have a bank account. There is no legal age limit at which you can open a bank account but a bank manager can decide whether to allow a child or young person to open an account. Parents can put pocket money directly into their child's bank account and then children can use it to pay for things without carrying money. Saving or spending pocket money, working part-time and dealing with banks are all parts of the process of becoming a financially independent adult and having to earn...
