读写任务
阅读下面的短文, 然后按照要求写一篇150词左右的英语短文.
On Friendship
Everyone needs friendship.No one can sail the ocean of life single handed.We need help
from, and also give help to, others.In the modern age, people attach more importance to
relations and connections.A man of charisma(超凡气质)has many friends.His power lies in
his ability to give.
The term, friend, covers a wide range of meanings.It can be a nodding acquaintance, a
comrade, a confident, a partner, a playmate, a brother, an intimate etc.
As life is full of struggle and conflict, we need friends to support and help us out of
difficulties.Our friends give us warnings against danger.True friends share not only joy but,
more often than not, sorrow.
With friendship, life is happy and harmonious.Without friendship, life is hostile and
unfortunate.I have friends in the rank and file.Some are rich and in power.Some are low and
common.Some are like myself, working as a teacher, reading and writing and content with
the simple life we have.To many of my friends, I know what to treasure, what to tolerate and
what to share.I will never forget my old friends and keep making new friends.I will not be
cold and indifferent to the poor friends and will show concern for them, even if it is only a
comforting word.
