I'm taking a test and have to guess the right answer to the question after the article. 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... Question: Frederick Zimmerman would probably agree that _ . Options: A: parents should let their children talk most of the time B: children should watch TV programs selectively C: the conversation between parents and children should be two-way D: it' s no good for parents to correct their children' s mistakes when they are speaking

I'm taking a test and have to guess the right answer to the question after the article. Article: There are a lot of differences in life in the US that you can only learn by living here. 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: Which of the following statements is TRUE when you eat out in the US? Options: A: The tip always ranges from 10% to 20% of the total bill. B: You needn't leave a tip if you will never eat in the restaurant. C: It's unnecessary to tip the waiter in a restaurant. D: Tipping is not necessary in fast food restaurants.

I'm taking a test and have to guess the right answer to the question after the article. Article: As a teacher, I always think it right to teach my students to write about their true feelings and real experiences. But once I was puzzled about this. After explaining a text one day, I asked my students to write a passage about their families. All the students wrote quite well but the best of them all was the one written by a small girl. I was deeply touched by it. The girl's father had died years before and her mother had to work hard to support the family. Many times she had seen her mother working deep into the night but never seen tears on her face. Like her mother this girl also works hard at her lessons and she is really good at any of them. I even didn't know anything about her unlucky family. She always appears happy every day so she is really liked by us all, both the students and teachers. In order to make her an example to the class, I read this passage to the class. When I finished reading it I found my throat _ and my students' eyes full of tears. Some of them even wept in a low voice. After the class nearly all my other students wanted to hand in their pocket money for the daily use to help this girl. To tell you the truth, I was really proud of my students. But to my disappointment, this student of mine left the class even without telling me the next day. I don't know the reason why, can you tell me? Question: Which of the following is TRUE according to the passage? Options: A: The teacher asked her students to read the little girl's article by themselves. B: The little girl's father died of a traffic accident. C: The little girl's classmates were willing to help her. D: The little girl's mother blamed her for her writing.
