12、Save the Children”?A.English Corner B.Project HopeC.The Summer Camp D.Job TrainingBAre you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now,
13、 scientists are trying to understand shyness. They have some interesting ideas about why people are shy.Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, thes
14、e shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. As a result, they became shy.
15、At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.You may also be shy because of where you were born. When scientists studied shyness in differen
16、t countries. They found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure. In Japan, when people do not succeed, they feel ba
17、d about themselves. They blame（责备）themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends, or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less
18、about failure and are less shy.For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And dont forget if you are shy, you are not the only one.6. What

28、The Population ProblemThe population is one of the biggest problems in the world today. China has the largest population with 1.3 billion. Its about one fifth of the worlds population. A large population causes many difficulties, not only for every family, but also for the whole nation. It has become a serious problem. In many less developed areas, some parents prefer boys to girls. As a result, many girls cant go to school.I think we should do something to control the population. One answer is known as the one-child policy. It has worked well in controlling Chinas population.
