G15-05【副詞子句】 表條件的副詞子句之假設語氣篇(I)/G15-06【副詞子句】 表條件的副詞子句之假設語氣篇(II)清楚說明了if子句的用法，本文則是要說明其他用來表條件的副詞子句會用到哪些從屬連接詞或片語呢？一起來看看吧～
其他表條件的副詞子句一、unless = if…not 「除非」
E.g.: You can’t get this job unless you have experience in this area.
「除非你在這領域有經驗，不然你無法得到這工作」
= You can’t get this job if you don’t have experience in this area.
「如果你在這領域沒有經驗，你無法得到這工作．」
其他表條件的副詞子句二、
as/so long as 「只要」
= providing (that)
= provided (that)
= on (the) condition that
= only if
E.g. 1: I can come to the party as/so long as I can leave my office by half past five.
「只要我在五點半前離開辦公室，我就能去參加派對」
E.g. 2: Providing/Provided (that) there are enough seats, anyone can come on the trip.
「只要座位夠，任何人都可以參加旅行．」
E.g. 3: I will lend you my car, provided/providing (that) you fill-up the tank before giving it back.(改自成大112年英文A）
「只要你還車之前把油箱加滿，我就借你車．」
E.g.4: I’ll come to the party on (the) condition that you don’t wear those ridiculous trousers!
＝I’ll come to the party only if you don’t wear those ridiculous trousers!
「只要你不穿那條可笑的褲子，我就會去派對！」
提醒：only if 「只要」不要跟另外一個片語if only 「但願」搞混唷～if only的用法屬於假設語氣if子句句構的衍生用法，詳見G4系列文章
其他表條件的副詞子句三、given (the fact) (that) + S + V 「有鑒於...」
E.g.: Given (the fact) (that) he’s had only six months to do this, he has made much progress.
「有鑒於他只有六個月做這件事，他已經進步很多了．」
提醒：given這字也可以當介系詞用，直接接名詞或Ving
E.g.: Given his age, he is a remarkably fast runner.
「有鑒於他的年紀，他是個很快的跑者了」
