在用WHAT, WHERE, HOW, WHY, 在甚麼情況下需要在後面跟DO, DOES?

在一句問題含有一個動詞的時候就要使用do或does啦. 動詞就好似係eat, do, run, write, come, go, jump, 等等.
例如:
How do you do? 第二個do係動詞
Why does he come? come 係動詞
What do you write? write 係動詞
Where does she go? go 係動詞
還要記住, 在使用do/does的時候, 動詞是不可以被更該成其他形式, 例如過去式 (came, jumped, ran), 或現在進行式(doing, eating...)

How are you? Where am I? What is this? 在三句是沒有動詞的, 所以不要do/does.

這些都是簡單的解釋, 要多用才能真正的了解用法. 希望可以幫到你,

Where does it eat ?
