236. The Coast Guard is conducting tests to see whether pigeons can be trained to help find survivors of wrecks at sea.

(A) to see whether pigeons can be trained to help find

(B) to see whether pigeons can be trained as help to find

(C) to see if pigeons can be trained for helping to find

(D) that see if pigeons are able to be trained in helping to find

(E) that see whether pigeons are able to be trained for help in finding

這一題從沒有人問過，真是報歉，看來要問一個很笨的問題了

我可以理解A是最好的答案，但我很好奇，help可以直接加find? 動詞可以直接加動詞嗎

請教各位，謝謝

[考点分析]有些动词,如teach, want, tell等可接带to的动词不定式作宾语补足语,即构成teach/want/tell sb. to do sth.结构。但是,动词不定式作使役动词及感官动词的宾语补足语时应省去to。这些动词可归纳为"一感(feel),二听(listen to, hear),三让(let, have和make),四看(look at, see, watch, notice)。";在动词help后面作宾语补足语时,to可有可无。　　注意:以上省略to的动词不定式,在被动语态中都必须加上to,但let不能用于被动语态。
