条件状语从句 条件状语从句主要由if或unless引导: if条件句 1) if条件句:条件句用于陈述语气,表示 假设的情况可能发生,其中 if 是“如果” 的意思。e.g. If it rains, we will stay at hme. 如果下雨我们就待在家里。
2) 用法: (1)条件状语从句通常由连词if引导,意为“如 果、假如”,主句不能用be ging t表示将 来,而应该用shall, will。e.g. If yu leave nw, yu will never regret it. 如果你现在离开,你永远都不会后悔。(2)if “如果”,引导条件状语从句,主句用一般 将来时,从句则用一般现在时。e.g. If it rains tmrrw, I shan’t climb the hills. 如果明天下雨,我就不爬山了。
(3)主句是祈使句或含有情态动词,从句也用一 般现在时。 e.g. Please call me if he cmes next Sunday. 如果他下周日过来请打电话给我。注意: 宾语从句中的if与条件状语从句if的区 别。宾语从句中的if “是否”相当于 whether, 引导宾语从句, 时态需根据语境确定。如果主句用一般现在时, 从句可以根据具体情况选用时态, 如果主句用一般过去时, 从句必须用过去时的某种形式。
unless 条件句unless引导的条件句,表示强烈的否定。翻译为“除非……”“非……不可”。e.g. Yu will fail unless yu wrk harder. 你不努力就会失败的。 =Yu will fail if yu d nt wrk harder.注意: unless 从句里的谓语只能是肯定 式, 因为本身unless表示否定。
