解析这是一道细节题,由第二段中的"The problem is figuring out which time is which."可知,他们弄不懂孩子的心思,因为上文说了"Sometimes she wants to be treated like a little girl and sometimes like a young lady."。

7.Which of the following best explains "the wall of silence" in the last paragraph?

A.Teenagers talk a lot with their friends.

B.Teenagers do not want to understand their parents.

C.Teenagers do not talk much with their parents.

D.Teenagers talk little about their own lives.

答案C

解析根据第一段可知,作者的主要意图是说"relationship between parents and their teenagers",随着孩子们年龄的增长,令父母们最为担忧的是他们弄不懂孩子的心思,因此彼此的交流就少了。正如"They talk to their friends first,then maybe their teachers,and their parents last.",所以the wall of silence指的是孩子不愿同父母交流这件事。

8.What can be learned from the passage?

A.Parents are unhappy with their growing children.

B.Parents have suitable ways to talk with their teenagers.

C.Parents should be patient with their silent teenagers.

D.Parents should try to understand their teenagers.

答案D

解析最后一段是文章的关键,作者提到解决问题有三大途径:一是"create chances to...";二是"And they must give...";三是"Another...is a better way to know them."。因此,努力去理解孩子才是解决问题的办法。

　　Many people who work in London prefer to live outside it,and to go to their offices or schools every day by train,car or bus,even though this means they have to get up early in the morning and reach home late in the evening.

　　One advantage of living outside London is that houses are cheaper.Even a small flat in London without a garden costs quite a lot to rent.With the same money,one can get a little house in the country with a garden of one's own.

　　Then,in the country one can really get away from the noise and hurry of busy working life.Even though one has to get up earlier and spend more time on trains or buses,one can sleep better at night and during weekends and on summer evenings,one can enjoy the fresh,clean air of the country.If one likes gardens,he/she can spend his/her free time digging,planting,watering and doing other jobs which are needed in a garden.Then,when the flowers and vegetables come up,one has got the reward together with those who have shared the secret of nature.

Some people,however,take no interest in country things:for them,happiness lies in the town,with its cinemas and theatres,beautiful shops and busy streets,dance-halls and restaurants.Such people would feel that their life was not worth living if they had to live outside London.
