　　Part Ⅴ 写作指导

　　Writing Sample

　　As a human being,one can hardly do without a friend.Society is made up of individuals,and making friends is a very important part in our life.Friends can give you a lot.First,if you have trouble with some problems,you can consult your good

　　friends and exchange opinions.Thus,you will feel comfortable and encouraged.Secondly,if you wish to do some physical exercises,such as playing table tennis,you could play with friends and have a good time.

　　But what is true friendship?Some people think friends are people whom they can play with.In my opinion,a friend in need is a friend indeed.True friendship can encourage you when you are in difficulties.A true friend not only shares with you

　　your joy and happiness but also your trouble and anxiety.When you need him,he

　　will give you a hand and spare no efforts.

　　As far as I'm concerned,I wish to make as many friends as possible.The world is

　　a big family,and we will feel relaxed in a friendly atmosphere.I wish some day we can all be friends.
