条件状语从句 概念 状语是句子中的修饰成分，用来修饰动词、形容词、副词或整个句子，表达时间、地点、原因、方式、条件、程度等概念。 状语从句，即在复合句中，充当状语成分的句子。 条件状语从句 功能：表示主句动作发生的条件。 常考连接词：if（如果）, unless（除非 = if...not）, as long as（只要） · if（如果）：表示 “当条件成立时，结果会发生” 例：If it rains tomorrow, we will cancel the picnic. · unless（除非）：相当于 “if…not”，表示 “当条件不成立时，结果会发生” 例：He can’t get the job unless he improves his communication skills.（除非他提升沟通技巧，否则无法获得这份工作。） · as/so long as（只要）：强调 “只要条件满足，结果就会发生” 例：You can borrow my book as long as you return it. · unless=if...not，注意否定转换： 例：You won’t pass the exam unless you study hard. = You won’t pass the exam if you don’t study hard.（除非努力学习，否则你考不过。） 时态规则（主将从现，主情从现，主祈从现）： · 时态必须遵循：主句（结果部分）用一般将来时、情态动词或祈使句, 从句（条件部分）用一般现在时： 将来时：If it rains tomorrow, we will stay at home. 情态动词：You can join us unless you are busy. 祈使句：As long as he arrives, call me. 练习：用If/unless/as long as 填空，完成句子 1. _________ you come to the party, you'll have a great time! 2. __________ it snows tomorrow, we will build a snowman. 3.
