[問題] 大全987-Q446

[hyt]

446. It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.
(A) again venture to Mars, a planet now known to be
(B) venture to Mars again, a planet now known for being
(C) will venture to Mars again, a planet now known as being
(D) venture again to Mars, a planet that is known now to be
(E) will again venture to Mars, a planet known now as being
Ans:(A)

請問這題有要注意時態嗎? (venture)
venture...again和again venture意思上有何不同?

[Behemoth]

我覺得沒有不同

另外,本題主要考察known的用法

[hyt]

可是如果單純是現在式, 那麼venture要加s吧!?...

[joycewin]

這裡的spacecraft 應該是複數 spacecraft 單複同形

[keane0727]

本人文法不精；以下部分是猜測需要各位驗証：
1. 時態需要考慮
題目應該是用x will/shall/may happen, before Y happens (happens 是現在式)
example: I will call you again before you leave office 正
I will call you again before you will leave office 誤
Lock the door before you will leave誤

2. again的位置有差別
again venture to Mars, a planet now known to be
a planet同位語修飾Mars，所以最好要緊鄰Mars
again搬到venture前面最清楚修飾venture

表時間的副詞子句以現在式代未來式 => (A) (B) (D) 選一個;
(B) known for being => 不選;
(D) now 的位置可能理解為火星現在才冷,乾,... (以前不是?); again 的位置也不好(two-way modifier) => 不選;
=> (A)
