四.阅读理解(20分)【Reading Comprehension】
Passage A
Dear editor,
Why do newspapers have so many advertisements for electronic(电子的)equipment? Last Sunday I counted ads. for seven kinds of televisions and thirteen kinds of radios in the Youth Journal. Besides that, there were pages and pages of ads. for Citizens’ Band radios and tape recorders.
Don’t you realize what electronic equipment is doing to our daily life? Everywhere you go you may hear loud music and advertisements over radios; this continuous noise is doing harm to our ears. Husbands don’t talk to wives any more; they are always watching the news or a ball game. Children’s eyes become hurt with endless hours of watching not only the programs for children but also those for grown-ups as well. And worse, hidden microphones find out our personal lives, and computers keep records of personal information about us.
That is enough! I think you should limit the amount of advertising of electronic equipment in the Youth Journal, or it will make life unbearable(难以忍受的)for us all.
1. Youth Journal is the name of _________. .
A. a department star B. a shop that sells electronic equipment
C. a local newspaper D. a hotel where the writer stayed
2. What problems does Jason Smith think radio causes?

C. It gives too much loud music. D. Its noise does harm to our ears.
3. Electronic equipment causes all the following problems EXCEPT that_________.
A. personal information is given to strangers. B. children’s eyes are harmed
C. news of the world is given to all people D. family members don’t talk to each other
4. It is NOT mentioned but implied(暗示)that _________. .
A. some kinds of electronic equipment are bad for our personal lives
B. watching too much TV hurts children’s eyes
C. some kinds of electronic equipment cause social problems
D. television has had effects on both grown-ups and children
5. From the letter, we know that _________.
A. the editor agrees with Jason Smith
B. the editor likes the electronic equipment ads
C. the editor doesn’t like the electronic equipment ads
D. Jason Smith doesn’t like the electronic equipment ads
