as 和be我不太懂得怎么用，麻煩大師講一下，3q!

熱心網友

as 和be不太好比較--它們不是一類詞。as：eg：1. As a child， he is clever enough.=Being a child， he is clever enough.（作為） 2. As is known to all，taiwan belongs to China.（連接代詞-指代從句）3. He can‘t come as he is ill.（因為）4. Child as he is ，he knows 2 foreign languages.（雖然）5. They laughed loudly as they came downstares.（當...時候）當然還有很多的用法，如與動詞搭配等。
