Key Points
New words
as if 表示 “好像、似乎、仿佛”(引导表语从句或方式状语从句)
两大核心用法(重点区分)
1. 虚拟语气(与事实相反)
从句动词需根据时间调整时态,体现 “非真实”。
对现在事实相反:从句用过去式(be 动词统一用 were)。
例:She talks as if she knew everything. 她说话像什么都知道似的。(实际不知道)
对过去事实相反:从句用 had + 过去分词。
对将来事实相反:从句用 would/could/might + 动词原形。
2. 陈述语气(与事实相符 / 可能性大)
从句动词用相应的时态(现在时、过去时等),无需变形。
主语为 it 时,常用 “it looks/seems as if…” 结构。
例:It looks as if it is going to rain. 天看起来要下雨了。
