Good morning, boys and girls. Today I’ll talk about going online.

We know that there are too many Net bars(网吧)around us. The Internet makes our lives interesting. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more information around us. It can make us clever in playing computer games. Also when we send e-mails to our friends, they can get them at once. It can help us keep in touch with people from all over the world.

But some students spend too much time in playing computer games and some stay in the Net bars all day and all night. It takes them too much time to chat online so they do worse in their lessons and they don’t study well any more. I think we mustn’t get online when it is time for us to study. We can do it in summer or winter holidays. I think we should get online with our teachers or parents.

At the same time, if we have lots of free time, we can do some activities after school. We usually have activities from 4:50 to 5:50 in the afternoon. We can play basketball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoon. I hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

That’s all! Thank you.

Your parents always tell you that a good education is the key to a successful future. For those of you who have or will be graduating from high school, the promise (允诺)you made to finish your schooling has been completed. Another few years in some college classroom just doesn't sound too attractive(有吸引力的) , so what are your choices? Let's see, Choice l- You can live with your parents, leech on to them, and do nothing. Or Choice 2-You could get yourself a job. Of course, there are other choices, but for this little discussion, we'll just suppose that they are not related(相关的).

Okay, so Choice 2 is obviously going to be more useful. You will finally be entering the real world. What would be a good place to start? Well, hopefully high school helped to give you some kind of an idea of what type of job you would like to enter. If not, then it would be a good idea to speak with an advisor or a person working in the field you may be interested in before you jump into a job that you won't like. Getting knowledge on a particular line of work beforehand can be good by helping you in your search to find the job that you will enjoy doing. Another reason to research jobs and get some hands on work is related to the fact that it will also be helpful in providing you with some valued experience. Internships(见习) or volunteering are usually a good place to start.

If you are ready to begin a job after high school, you will clearly be saving money from high college cost and happily making a living in your chosen jobs, From another point of view, jumping into the workforce is sometimes the only way to see for yourself if you are ready to work a 40-hour week yet. If you decide that full time work is not what you are ready for, then this may suggest that you should go back to school and get a degree. Besides, a college degree will usually mean higher pay.

1.The underlined phrase "leech on to" in the first paragraph might mean_______.

A. deal with B. care for

C. quarrel with D. depend on

2.Which of the following isn't mentioned in helping you find a job?

A. Ideas about getting a job in high schools.

B. Advice from teachers and parents.

C. Internships and volunteering.

D. Experience from work.

3. The advantages of starting work right after high school include the following except______.

A. getting to know if you should go back to school.

B. making sure if you are really ready to work

C, getting higher pay

D. saving money

4.The best title for this passage might be

A. Going Back to College

B. The Place Where I Should Start

C. Jumping into Work after High School

D. The Advantage of Starting Work Earlier
