IV．阅读理解
A
We can use computers to find lots of information online．The Internet is a very useful system．For example，even though I ’m in my hometown，I can easily get information about another part of the world，such as how the government works in Texas．
However，ther ( http: / / www.21cnjy.com )e are some problems with it too．Sometimes I hear about hackers(黑客)．For example，once I heard about a large telephone company that showed all of its customer’s information．’This happened because it is too difficult to make information safe on the Internet．Only five years has passed since the Internet was popularized，and it has been improving very quickly．I guess there are many criminals (罪犯) who use the Internet．The Internet is developing very quickly，so we need to find ways to make it safer．and to keep other people from seeing our secrets．
Another problem i ( http: / / www.21cnjy.com )s that many children are good at using computers．They can use the Internet to go anywhere，even to the sites that are only for adults．There are many adult sites about sex and violence．If children want to see them，they can find them easily．They aren’t blocked，and this can be very harmful for children．
It is very diffi ( http: / / www.21cnjy.com )cult to solve this problem．We can’t say it’s only the parents’ responsibility because the Internet is a new technology to them．Instead，it should first be limited or ruled by the government．Then parents should try to learn about this system so that this problem can be solved gradually．
1．The writer thinks that _______________．
A．the Internet ca ( http: / / www.21cnjy.com )n only be used to find information B．the Internet can’t be used by children
C．the Internet are ( http: / / www.21cnjy.com )useful but there are disadvantages D．we can’t do anything without the Internet now
2．It can be inferred from the second paragraph that__________.
A．the telepho ( http: / / www.21cnjy.com )ne company is a big hacker B．the telephone company did that together with hackers
C．nothing is s ( http: / / www.21cnjy.com )afe on the Internet D．that telephone company’s information was stolen by hackers
3．How many negative aspects are mentioned in the passage
A．Two． B．Three． C．One．D．Four．
4．Which of the following is NOT mentioned in the passage
A．Parents should tak ( http: / / www.21cnjy.com )e more care of the children who like surfing the net．
B．Some sites which are not fit for children should be controlled．
C．Governments should do something to make the Internet cleaner．
D．Teachers should teach students to stay away from the Internet
5．Computers are harmful to children；the reason is that
A．they are good ( http: / / www.21cnjy.com ) at using them B．they can use the Internet to go anywhere
C．they see many film ( http: / / www.21cnjy.com )s on the Internet D．they go to the sites about sex and violence
