听力原文：M: So, you must have a lot of contact with overseas students in your work helping people coping with daily existence.
W: Sometimes. You know the life of a social worker is not all wonderful and working to help people in their daily life. I have to spend a lot of time pushing paper, and writing reports too. But when I do get out, yeah, I see a lot of foreigners. And sometimes they come in because life in America has just beaten them down and they can't cope financially or emotionally.
M: Really？ I would think that they had a good support network in place, especially university students.
W: They do have a network, and a variety of support groups, but these can't meet all of the students' needs. They can't help with paying bills, dealing with American neighbors and customs, fitting in, getting a driver's license, etc. They try, but very often the student has to figure out a lot of this stuff by himself. And if he or she is shy, they don't have the courage to ask other people, even other people from their nationality.
M: So what are some of the things that overseas students struggle with？
W: This might interest you, but they struggle with the food, especially Chinese. You know, they come here knowing that Americans love Chinese food so much. They think that there will be good restaurants with Chinese food that they love. But they get here and they are extremely surprised. Americans enjoy totally different flavors.
M: So what do they do？
W: If they're brave and curious, they look around and test all the restaurants. There is usually at least one restaurant in every town that has almost quality food.
Questions 23 to 25 are based on the conversation you have just heard.

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present languages of Europe and India are modern forms of the language of 4,500 yeas ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. Some even die out completely. About 1, 000 years ago English was a little-known relative of German spoken on one of the borders of Europe.
If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by millions of speakers. Their differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China cannot understand speakers from other parts.
The first paragraph mainly tells us that ______.
A．most people in the world speak Chinese
B．there are thousands of languages in the world today
C．man has much knowledge about languages
D．some people know several languages

Mobile phones are the items that a lot of people are having today. However，do we really need to have a mobile phone by our side？
We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.
But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.
Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.
