needn't do 和dont need to do希望得到详细的语法解答!
题目是这样的：We need some cakes for picnic.划线提问some cakes
______ _______ we need for picnic?
2根横线填什么?what food?还是 which food?还是 what do?
然后把题目原句改成否定句和一般疑问句怎么改?we don't need 还是we needn't?
我们需要读一些书翻译是：We need read some books 还是We need to read some books?
答
首先,你要弄清楚need在这句中做动词而不是情态动词问句里必须有助动词所以横线填what 容易吧既然need是动词那么否定句当然是we don't neet 也不难吧!need的情态动词用于否定句和疑问句那么翻译部分是个肯定句由此可...
