在條件子句中的引導子句的連接詞?引導子句的連接詞,通常是if,然而有哪些字可替換?有那些例子? -----

"if"作為"引導條件子句的連接詞"功能時，可以替換的字有不少：
in case / in the event that / provided (that) / providing (that) / on condition that / supposing that / assuming that

例句：
Go without him if it rains tomorrow. = Go without him in case it rains tomorrow. = Go without him provided that it rains tomorrow. ... (假如明天下雨，不用跟他一起去)

有個 Highbeam 百科引用牛津字典解釋請參考，"if"：
if (The Oxford Pocket Thesaurus of Current English ...) if • conjunction 1. if you go, he will go synonyms : on condition that, provided, providing, supposing, assuming, on the assumption that, allowing that.
