關於英文假設語氣的問題?

2019-03-15 4:45 am
我的英文題本裡有一題是:
This purchase _______ a poor decision if it had been made for investment purposes only.
選項中有這兩個答案:
(A)would have been
(B)would be
解答本上給的答案是A
但我想問的是 B 答案難道不行嗎?
因為我翻譯起來兩者應該都可以,只是意思有些微不一樣
選項A"如果僅為投資目的而進行,那次購買就是一個糟糕的決定"
選項B""如果僅為投資目的而進行,那次購買會成為一個糟糕的決定"

✔ 最佳答案
This purchase _______ a poor decision if it had been made for investment purposes only.
由this purchase的語意來看:加上this,表示採購已經成交了(是存在的事實),而且「是」一個「好」的決定。現在我們「假設」它是個「壞」的決定,所給的條件就是「虛假的」,過去未曾發生或過去不存在;對過去事件的不實假設,就要用「過去完成式」,「條件句」裡用的是had been made(make的過去完成式被動態)。「結果句」的時序在「條件句」之後,動詞也要用「過去完成式」,但要加上過去式助動詞would,表示時間點在條件句之「後」,即would have been。

would be是用在「現在/將來不可能存在」的狀況,如:
If we "had stayed" in that hotel, we "would be" dead now.(我們「現在」沒死呢!)

但poor decision從過去以來一直都不是事實,所以不能用would be。

Hi 補充新觀念: tense, aspect, modality 為一體三面。
1). tense 僅着重present 與past。
subjunctive中,if 可表顛倒說,
時點往前移, present 移為past,
past 移為 past perfect。
It's time you went to bed. (主句現在時)
2). modal 情態助動 would, will
表說話者mood,當下意望之婉轉、堅決。以當下modal,意謂過去時,
就以would have + pp表達。
I would like to see you soon. (非過去時)
I should have given you the gift. (過去時)
3). 本題傳統套招,if 既是 had + pp,
主句當是modal 過去時 。出題者拿
modal 意謂過去時,考考罷了。
4). 這些形式表達,容易學。說寫使用時,可多研習 verb pattern 之用法 (usage),不僅僅是背記vi 或vt。

If it had been made for investment purposes only-----If Clause
this purchase would have been a poor decision-----Main Clause
Example (A) states that investment had not been made;
then the purchase would not have been a poor decision.僅為投資,未必糟糕.
Example (B) should would be used in Main Clause, then If Clause should use Past(in fact, subjunctive Improbable Condition)=was made =it is unlikely to do so.若為投資,便糟糕?

(A) would have been
Conditional Sentences Type-3 句子不是你這樣子翻譯的,應該說明 "購買不是只為了投資" 這過去的事實 -

這次購買沒有僅為了投資目的而進行了,不然它已是一個錯誤的决定。
