On a hot August morning, in a classroom overlooking New York’s Hudson River, a teacher guides a group of 3-year-olds completely in Chinese. This is just a language summer camp run by the primary school Bilingual Buds, which offers a year-round course in Chinese as well as Spanish for kids as young as 2.

A lot of research now shows the regular, high-level use of more than one language may actually improve early brain development. Knowing two or more languages can improve the ability to focus, decide and deal with information better. These important skills are grouped together, known in brain terms as “executive function”. The research suggests they develop ahead of time in bilingual children, and are already evident in kids as young as 3 or 4. Bilingual education, common in many countries, is a growing trend across the United States, with 440 elementary schools offering the study in Spanish, Chinese and French.

But Tamar Gollan, a professor at the University of California, has found a vocabulary gap between children who speak only one language and those who grow up with more. On average, the more language spoken, the smaller the vocabulary in each one. Gollan’s research suggests that while that gap narrows as children grow, it does not disappear completely. Gollan says, “Vocabulary tests help us find that bilinguals have the disadvantage, where you know the word but you just can’t get it out.”

In fact some of the values of bilingualism can’t be measured at all, of course. To speak more than one language is to open the mind to more than one culture or way of life.

Bilinguals also appear to be better at learning other new languages. Clarisse spent her early childhood in Switzerland speaking French. At 6, she learned English. Later she learned Spanish, German, and, during three years living in Tokyo, Japanese. Now she has easily mastered several languages.

1.Why should children learn more than one language according to Paragraph 2?

A. Because it can do good to children’s brain development.

B. Because it’s part of a language summer camp.

C. Because it is common in many countries.

D. Because it is popular with children.

2.The underlined word “they” in Paragraph 2 probably refers to _________.

A. many countries

B. bilingual children

C. these important skills

D. two or more languages

3.According to Tamar Gollan, __________.

A. knowing two or more languages can improve children’s skills

B. the more languages children know, the better they will be

C. children had better not take vocabulary tests

D. bilingual education is not always good to children

4. From the passage we can learn_________.

A. Clarisse likes French best instead of Japanese

B. bilingual education is mainly loved by children

C. bilinguals can have a disadvantage in learning other new languages

D. knowing more languages can help children learn more about foreign cultures

We all go through times when we feel we are not good enough. We might feel that way at work or in school or even as a parent. Here are some things to remember when you feel like that.

1. —1.—. When I started my Ph.D. program, I felt like the dumbest person in every class. I couldn’t believe how many smart people were there. I didn’t know if I could measure up to their intelligence or compete in the same league with them. Years later, I found out that almost everyone felt this way, too.

2. You are unique and have special talents. If you can barely make Hamburger Helper, don’t compare yourself to your sister who is a chef(廚師). I’m sure you can do many things that she can’t. —2.—. You are you. You are not your sister.

3. You need to stop chasing perfection. It doesn’t exist. —3.—. So if you think that there is some objective measurement of perfection and that the rest of the world is judging you against, then you are wrong. Most people are too worried about their own lack of perfection to judge you.

4. —4.—. Our sense of self-worth is based in our thoughts. We have been programmed for many years with thoughts about ourselves. Messages come from our parents, our peers, teachers, the media and our own labels. But guess what? They are only thoughts. Just because you think these thoughts, it doesn’t make them true. —5.—.

A. You have the power to change your future.

B. So focus on your own passions and talents.

C. You are not the only one who feels this way.

D. You need to change your thought patterns.

E. What’s perfect to me is not perfect to you.

F. If you love yourself for who you are, other people will notice.

G. One of my favorite sayings is, “Don’t believe a negative thought you think!”

My friend Li Hua used to be rather poor in English, especially his terrible and strange pronunciation. Hardly could he make him understood when speaking English. Bearing a heavy load in mind, he felt desperate and upset. He dared not speak English at class. When asked questions, she was always nervous and embarrassed. The classmates always make fun of him, saying that he was speaking Japanese! Once I met him in the corridor. I told him that his pronunciation was very special and a kind of like Obama's. Believing what I said, he got greatly inspired. He spared no effort to practice speak English every day. Now, he can speak English fluent with a perfect accent.

Recently, he told me that it wasn't long after he knew that I just told a little white lie then but he appreciated badly, without which, he said, he couldn't have achieved such great progresses.
