I dont think she can do it without you，（ ）？

I think she can do it He think she can do it改为否定句 为什么~

I don't think she can do it.
He doesn't think she can do it.

否定要前移

若有疑问及时追问，满意敬请采纳，O(∩_∩)O谢谢~~

照理说第二种应该是错误的。
第一句的意思就是 我认为她不漂亮。
当主语为 I 或者We时，think从句若要否定，只能在think前加否定词。
如：I don't think you are right.
我认为你是错的。
而不是 我不认为你是正确的。
当然，如果主语是第二第三人称就不遵循这个定理了。
如：She don't think Amy is clever.
她不认为Amy聪明。
而不是 她认为Amy不聪明。

can she?

这是反义疑问句，后面应该是 does she
翻译成中文是：我认为（相信）没有你她做不成这件事，不是吗？

does she 我认为该句是否定句 因为dont think 表主观意愿 反问应反问从句

doesn't she

can she

陶褚联可： isn't she 因为前面是肯定,所以后面是否定,要用not 相反,如果前面是否定,那后面就是肯定了 至于用IS不用MUST是因为反义疑问句反问的是宾语(也就是SHE),不反问情态动词,记住就行了,这是普遍规律 如果还有不懂得,问哦
