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?

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以知道用做动词的：We need to read some books
上面的是一些答题技巧,但你要学好英语希望不要仅限于技巧!
