Good morning, class!

     We know that there are too many net bars around us. The Internet is popular and it makes our lives

colorful. Many of us like going online very much because we can learn how to use the computer and get

more information from the Internet. We can learn English. We can read some good newspapers and

magazines. It can make us clever in playing computer games. We can send E-mails to our friends quickly. We can chat(聊天) freely online with our friends. It can help us get in touch with people from all over the world.

     But some students spend too much time in playing computer game and some stay in the net bars all day and all night. Teenagers even get to have boyfriends or girlfriends online. They write too many letters to

each other. It takes them to much time to chat online so they do worse and 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. We should get online with adults(成人)--our teacher or parents.

     At the same time, if we have lots of free time, we can do some out-of-class activities at school. We

usually have activities from 4:50 to 5:50 in the afternoon. We have different kinds of activities. If you are

interested in sports,you can play basketball or football.We can go to the English Corner.We can practice

talking in English there. We 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.

     Thank you for listening to me. That’s all.

材料一：“昨日入城市，归来泪满巾。遍身罗绮者，不是养蚕人。”（张俞《蚕妇》）“只向贫家促机杼，几家能有一絇丝。”（王安石《促织》）

——摘编自李明伟（清末民初城市社会阶层嬗变研究）

材料二：各通商口岸输入洋纱统计表（1867~1892年）（资料来源：历年海关统计与报告）

材料三：郑观应提出：“欲制西人以自强，莫如振兴商务。……”原夫欧洲各国，以通商为大径，以制造为本务。……若有商而无工，徒弃已利以资彼用而已。即今力图设计，切勿薄视商工。……张謇在《代鄂督陈立国自强疏》中指出：“世人皆言外洋以商务立国，此皮毛之论也，不知外洋富民强国之本实在于工。讲格致（清末对物理、化学等自然科学的统称），用机器，精制造……此则养民之大经，富国之妙数，御侮自在其中。”

——摘编自《张之洞评传》

材料四：1922年爆发棉纺织业危机，大生纱厂危机严重，当时政府没有提供什么有价值的帮助。……日本在上世纪20年代初经济恐慌中采取了大规模的紧急救济措施，为各行业提供经济贷款援助。日本的大型企业、商业银行、股票交易所很快摆脱了困境，在随后的中日纱厂竞争中迅速拖垮了大生。……张謇寻求国外资金的支持，向美国资本家借款不成，大生无可挽回地走向衰落。
