"Do I need to?" VS "Need I do?"
问题描述：
"Do I need to?" VS "Need I do?"
我一直认为need作为实义动词,用在肯定句中,比如：I need to do my homework now.
作为情态动词,用在否定句和疑问句中,比如：You needn't give it back today?
Need she do that now?
但今天在新目标英语九年级14单元看到下面的：
-Have you cleaned your room?
-Do I need to?
回答是个疑问句,为什么不说Need I do?
答
need做为情态动词,只用于否定,疑问句
而作为实意动词,则都可以用.
所以do i need to并没错 Have you cleaned your room?
常见回答是： 1. Do I need to2. Need I 不需要+do
