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。

     Be grateful for friends

     It is a celebrating day. I got in touch with Michael whom I have been losing contact for one year.

     It is really magic. I was searching online aimlessly yesterday when an idea struck me suddenly: since

Ben can find out my secret by keying in my name in the search engines, why can't I do so, either?

     I intended to find out something about Ben in revenge in the first place, but soon extend my name list

to a wider category. It was then that I recalled Michael suddenly.

     We have lost contact since our last correspondence in my Senior 3. He mentioned to me in his last

letter that he was preparing for going to UK to further his education. I, shamefully, was too busy to reply

his mail then. When I won the final freedom, I thought he had already been in UK so I had no idea where

to write him.

     I used to think that we would never meet again. However, when I browsed the entries about him, I

found out excitedly that he is still in China.

     Without a moment of hesitation, I ran upstairs to my dorm and found out my old address book. Thank goodness, his home number was still there.

     After 3 times calling with no answer replies, I eventually got him on the phone. He was more surprised

than I could imagine that when I asked for his home number he was too nervous to remember it.

      Life is enjoyable in moments such like this. Old friends meet again surprisingly, on a road of their

own ways to their dreams. They look at the face of each other, and recognize the old pal. It is such

moment that makes me feel grateful to life: whenever I set off for a new destination, I see I have friends

in the same direction, with whom I won't feel alone any more.
