Нужно задать 10 вопросов на английском. пожалуйста. по тексту.
1. Everyone agrees that education is a very important matter, but not
everyone agrees about the best way to teach children. One controversial
question that people disagree on is whether girls and boys should be educated
separately.
2. There are several advantages to single-sex schools. Firstly, schools can
concentrate on teaching subjects that interest students must. For example,
girls are often more interested in languages and an all-girl school can find
more time for such subjects in the timetable. Secondly, many people think
that girls and boys learn better in classes of the same sex. They say that there
is more competition between students and that generally results are better.
Finally, supporters of single-sex schools also believe the students are calmer
and behave better, too.
3. However, there are many arguments against single-sex schools. Firstly,
critics of such schools say that they encourage young people to make
stereotypical choices about their futures. This is because students often don't
have the chance to try things which are less typical for their gender. But
perhaps the biggest disadvantage is that they do not give boys and girls a
chance to socialise with each other. This can make it hard for people to adapt
to the 'normal' world after they finish school.
4. In conclusion, although single-sex schools can be a good thing,
especially academically, they also have a negative side. In mv opinion, the
biggest argument against these schools is that they do not give young men and
women the chance to understand each other better.
