写作题

写作.

阅读下面的短文,然后按要求写一篇150词左右的英语短文.

     What my mother does drives me crazy.She calls me at 10:30 p.m. every night to make

sure I've arrived home safely.If I accidentally miss her call,she will keep calling all my friends

and roommates until she "tracks me down".

     As a 20yearold lady in Beijing,sometimes I have to ask my friends to be quiet so that I

can pick up my mother's phone call,telling her a white lie that I'm already at home.

     Recently I ran into a matchmaking meeting,which is held in a park and specifically designed

for single white-collar workers in Beijing.The interesting part is that all of the attendees are

single people's parents,eager to look for a life partner for their children.

     One mother told me that her 33yearold son is busy with his career and has zero time to

find a suitable girl for himself.So she goes to the matchmaking every week,trying to find her

son a perfect bride.

     She guaranteed that her future daughterinlaw doesn't need to worry about anything for

she has prepared an apartment and a car for them,and if they can't find a kindergarten near

the apartment she has bought,she will buy them another one.Looking at hundreds of

middle-aged parents standing in the cold outdoors in a freezing winter trying to build their

children a perfect future,I suddenly understand my mother more.
