Dear Annie,
   I have never written a letter to a newspaper before, I have just never felt the need to do such a thing. I have always felt I was quite able to do everything by myself. But now I know I was wrong.
   Sometimes you really need help in life, I guess. And that's why I'm writing this letter to you.
I have a happy family. I love my children and they love me . I'm a mother of three children. I know well how to bring up (带大)children, and two of them are already over twenty, so it is nothing new for me.
   But now I have a serious problem: the Internet problem. My little son is just sixteen, and I feel he should do a lot of homework now , but he doesn't seem to be interested in it . He can happily spend six or eight hours at a time on the Internet every day , He chats with people that he has never met before , but speaks little to us .He does lots of useless things on the Internet. And he sees red if you ask him to do his homework.
   I just want him to be a good student . Now he seldom does his lessons at home. I'm afraid he will drop behind in his class soon. His father is a doctor , a very kind man . He never seems to be afraid of his father.
What can I do ?And don't tell to talk to him. We've tried that and it didn’t work. But this is really a big problem in our family. I have tried everything I can think of . I wonder how the Internet is so attractive(有吸引力的).You're my last hope. Please tell me what I can do!
Yours,
Ellen Smith

河中石兽

    沧州南，一寺临河干，山门圮于河，二石兽并沉焉。阅十余岁，僧募金重修，求石兽于水中，竟不可得。以为顺流下矣，棹数小舟，曳铁钯，寻十余里，无迹。

    一讲学家设帐寺中，闻之笑曰：“尔辈不能究物理，是非木杮，岂能为暴涨携之去？乃石性坚重，沙性松浮，湮于沙上，渐沉渐深耳。沿河求之，不亦颠乎？”众服为确论。

    一老河兵闻之，又笑曰：“凡河中失石，当求之于上流。盖石性坚重，沙性松浮，水不能冲石，其反激之力，必于石下迎水处啮沙为坎穴，渐激渐深，至石之半，石必倒掷坎穴中。如是再啮，石又再转，转转不已，遂反溯流逆上矣。求之下流，固颠；求之地中，不更颠乎？”

    如其言，果得于数里外。然则天下之事，但知其一，不知其二者多矣，可据理臆断欤？
