development and special steps are being taken to spread the Internet all over the country.
This is considered as a great achievement and it is. But here is a question whether our people know the
use of the Internet for development purpose. It is a fact that the ratio (比率) of informative and educational
sites is very low.
What do many of them do in Pakistan when people surf the Internet? They use it mostly for entertainment.
Many students spend a lot of time and money in surfing the Internet. They do chatting or visit other
entertainment sites. It is surprising to read that boys and girls go to the Internet cafes and spend many hours
daily in just chatting. just join any Pakistani chat room at any site, and you will know that what is the level
(水平) of language and which type of language mostly our people use in chatting. The number of the web
addicts in our country is increasing day by day.
It is also a fact that many people including teenagers visit sites unsuitable. One can imagine that they are
becoming worse and they are becoming addicted to such things that are very harmful (有害的) to them. They
are taking all the disadvantages from the Internet.
Students do use the Internet for education purpose. But there are also several disadvantages. Students
normally surf more on the Internet than teachers. It happens several times that a teacher gives some work
to students and they get it from the Internet, copy it and present it to the teacher, who many times is unable
to know what is copied from the Internet. In this way students are giving up the habit of reading books. They
just open sites, copy the information and finish the homework that they do not even read. However, a very
good advantage of the Internet for students is that those who want to seek knowledge can get information
very quickly and read many books by famous foreign authors which are very expensive to buy.
The Internet itself is a very useful and important tool of development nowadays, but it is really sad that in
Pakistan people are mostly misusing it. Those who use it for development purpose are still very few.
B. The very useful and important tool in Pakistan.
C. The worrying situation of using the Internet in Pakistan.
D. The advantages and disadvantages of the Internet in Pakistan.
B. People who are not able to free themselves from the Internet.
C. Entertainment sites of the Internet which are harmful to teenagers.
D. Internet cafes where boys and girls spend too much time in chatting.
B. to advise readers to use proper language in chatting rooms
C. to ask readers to pay attention to the problem in using the Internet
D. to stop readers from going to the Internet cafes or misusing the Internet
