【题目】 Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Now, 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. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic (遗传的).

Family size might cause people to be shy as well. Scientists found that 66 percent of shy children had older brothers and sisters. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play with 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. Scientists found surprising differences about shyness in different countries. In Japan, most people said they were shy. But in Israel(以色列), only one of three people said so. What can explain the difference? One scientist says the Japanese and Israelis have different opinions of failure.

For shy people, it can be difficult to make friends and speak in class. But scientists say you can get over your shyness. They suggest trying new things and practicing conversations. And_don't_forget—if_you_are_shy,_you_are_not_the_only_one.
