题目内容
I don't think your friend________worry about your son．I think he will be all right soon．
- A.need
- B.needs
- C.need to
- D.not need to
A
分析：要注意I don't think跟宾语从句时有否定转移的概念，所以要把四个选项看成否定形式，并且跟上后面的动词，A项是needn't worry about，是正确结构，B项是doesn't need worry about，是错误结构，C项don't need to worry about，本身是正确结构，但和主语your friend结合在一起，属于主谓不一致的错误，D项本身是否定，再否定就变成肯定了，而且这种否定的形式是错误的。所以应该选A项。(延伸)I don't think your friend need worry about yourson．中的need是情态动词，按理说不可以用在肯定句里，但由于这里有否定转移的概念，所以又成为正确的结构，是应该注意的问题。(题型变化)本句＝I don't think your friend needs to worry about your son．
