表因果关系的连词

　　[例1] You must put things there you can find them.

　　there→where。此处应由where引导地点状语从句。

　　[例2] I remember the time as my grandmother was telling stories to me.

　　as→when。when引导名词性从句，表示"……的时候"。

　　[例3] A child as he was,he looked quite calm in that difficult situation.

　　去掉A，child的首字母大写。as引导让步状语从句时，前面作表语的单数名词前不加冠词。

　　[例4] Don’t make friends with such people that you think are dishonest.

　　that→as。such...as...搭配在一起用，as引导定语从句。

　　[例5] He had been admitted by Beijing University made us very happy.

　　句首加That，把He改为he。that引导名词性从句，本身无实际意义，也不作成分，但不能省略。
