A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question iswhether tourists will continue to visit game parks and see rhinoceroses after their horns aretrimmed.
(A) whether tourists will continue to visit game parks and see rhinoceroses after their horns are

(B) whether tourists will continue to visit game parks to see one once their horns are

(C) whether tourists will continue to visit game parks to see rhinoceroses once the animals’ horns have been

(D) if tourists will continue to visit game parks and see rhinoceroses once the animals’ horns are

(E) if tourists will continue to visit game parks to see one after the animals’ horns have been
在宾语从句中，只能用whether引导，对吧？那表语从句呢？？

whether和if都能引导宾语从句呢，举个例子——He asked me whether/is I could help him.

但whether可引导表语从句，if不能。如： The question is whether we can get there on time.

希望对LZ有帮助~~
