Question

求助：几道英语选择题（语法)

1._____to take this adventure course will certainly learn a lot of useful skills.
A.Brave enough students B.Students brave enough
C.Enough brave students
按理说，enough应放在adj后，名词前。应该选A,可为什么选B?
2._____be sent to work here?
A.Who do you suggest that should B.Who do you suggest
按排除法我知道选B.但为什么题干中是"be",而不是"is",也就是问为什么系动词用原型？
3._____,I have never seen anyone who is as capable as John.
A.As long as I have traveled.
B.Now that I have traveled
C.Much as I have traveled
D.As I have traveled so much
书中说，这是考察as引导让步状语从句的语序，要把一类词提前，那么为什么不选C而选A呢？
4.还有一个问题，比如说"I have something to do "与"I have something to be done"那个是对的？很多选择题中都有类似的。

感谢众高手的解答！！谢谢！！

Answer 1

第一题是一种前置倒装，用于强调brave。当强调brave时，brave会放在句首，此时students就成了在brave后面了。
第二题suggest做建议推荐解释的时候，后面是不带to的不定式。所以用be。
第三题as long as是在……的时候。本句解释为“在我一路上，还没有任何一个人像john一样能干。c我认为是语序错误。如果改成much as have I traveled，或者much as had traveled可能就对了。
第四题第一个是对的。have something to do （with），这个do应做被动解， 而且可以用到任何**thing to do 上。

Answer 2

我也是这样想的，，但是3题我也认为要选C啊
