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

正確答案是c
to v表達purpose
這邊用了兩個to v( to visit /to see)
感覺需要and連接~~???
麻煩大家幫我解答??

continue to visit...to see...
to visit 修飾continue
to see 修飾 visit

我比較有疑問的為什麼要使用完成式?

[Huang Hsin-Yi]

事件發生的時間點

因為第二句要說,如果犀牛角被修剪後,觀光客會怎樣.......
因此要用完成式表示 修剪在前,參觀在後的時間關係

[pinpink]

可是他提到參觀是用未來式will
那麼修剪用現在式仍然可以看的出前後關係阿?

[Huang Hsin-Yi]

grammar from longman:

When a dependent clause talks about a future time, use the simple present in the dependent clause and the future with will in the independent clause. Both verbs are future in meaning. The simple present shows the first future action, and the future shows the second future action.

Moreover, the tense in the first clause( A proposal has been made to trim ) indicated that the action, trim, already happen.

嗯~那又帶出我的另一個疑問了
whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been

我看這題時以為whether 才是連接詞, once只是副詞
而且once前面沒逗號，的確像是whether 子句放前面的樣子
這個句子也跟我記憶中dependent clause不能用未來式有衝突
總不可能兩個都是連接詞吧?

[dibert8]

whether 引導名詞子句,沒有時態限制.
once 是連接詞沒錯.

[dibert8]

可是他提到參觀是用未來式will
那麼修剪用現在式仍然可以看的出前後關係阿?

這題考到對等連接詞:連接"對等"的字義.
(A) to visit game parks and see rhinoceroses ... = to visit... and (to) see... 變成是兩件獨立的事情;時態無可厚非,對等連接詞用錯了.
(C) 的現在完成式讓句意表達更好些.
