     Do you have any strong opinion on co-educational or single-sex schools?

     A supporter of co-educational schools would probably say that schools should be like the societies they

belong to. In Hong Kong, men and women mix socially on a day-to-day basis. In many fields men are even

likely to have female bosses. It is, therefore, desirable that boys and girls grow up together,go to school

together, and prepare themselves for a society that does not value sexual separation.

     Some would go on to argue further that growing up with members of the opposite sex is important for

personal development. Regular contact (接触) can remove the strange ideas about the opposite-sex and lead

to more natural relationships. Single-sex conditions are seen as leading to more extreme opinions, and possibly

even as encouraging homosexuality (同性恋), though there is no proof that this is the case.

     Those who are against coeducation often also fix their attention on the sexual side. Some parents fear that

close contact with members of the opposite sex is dangerous for teenagers. They want their children to be

attentive to their studies. Such parents feel uncomfortable with modern ways and the free mixing of the sexes.

     A stronger argument comes from research into school results. Girls grow up earlier than boys, tend to be

more orderly and are likely to be better at languages. In a mixed class,boys who might do well in a single-sex

class become discouraged and take on the rule of troublemaker. Certainly in the UK this situation has greatly

alarmed (惊动) the government for it to be encouraging co-educational schools to have some single-sex

classes.　In the UK the best schools are all single-sex, strongly suggesting that co-education is not the best

answer. This may, however, not be as simple as it looks.It may simply be that the famous old schools that

attract the best students happen to be single-sex,　rather than that being single-sex makes them better schools.

A. students in single-sex schools will certainly become homosexual

3. Alarmed by the situation,the UK government encourages _____.

A. co-education

B. single-sex education

C. single-sex classes in co-educational schools

D. co-educational classes in single-sex schools

4. At the end of the passage the writer suggests that _____.

A. single-sex schools are the best schools in the UK

B. being single-sex does not necessarily make a school better

C. co-educational schools are better for both sexes in personal development
