未來條件句 III @ 宏浩翻譯有限公司

句型三：

If … were going to + 動詞 …, … would be + 現在分詞 …
… would be + 現在分詞 … if … were going to + 動詞 …

用法：

句型三的未來非事實條件句乃句型二的變化句型，同樣可用來談論未來虛構的情況。注意：句型三與句型二只有 if 子句不同。英語母語人士係使用句型三來強調這種條件句是一種計畫或預測，與 “be going to" 是用來表示計畫或預測的情況一樣。

例句：

If I were going to go to Fiji next week, I would be taking my scuba diving gear with me. (如果下週我要去斐濟，我會帶著浮潛裝備) －下週我不去斐濟，所以我不會帶著浮潛裝備。
If I were not going to visit my grandfather tomorrow, I would help you do housework. (如果明天我不去探望我祖父，我會幫你做家事) －明天我要去探望我祖父。

僅能使用 If

未來非事實條件句只能使用 if，不可用 when，因為它談論的是與未來事實相反的虛構情況。

例句：

I would buy that computer tomorrow if it were cheaper. (如果那部電腦比較便宜，明天我會把它買下來) (正)
I would buy that computer tomorrow when it were cheaper. (誤)

在未來非事實條件句中，除了 would 外，還可使用 should, could, might 這三個情態助動詞。

例句：

If I went to Saudi Arabia next year, I could learn Arabic. Unfortunately, that’s not possible. (如果明年我去沙烏地阿拉伯，我就可以學阿拉伯語。可惜的是，那是不可能的)
If I didn’t have to work tonight, I could go to the fitness center. (如果今晚我不必工作，我就可以上健身中心)
