专题06 重点语法归纳及专练(二)
一、连词unless, as soon as, so/such...that...的用法
n unless 连词,“如果不; 除非”,可转换为 if...not, 引导条件状语从句,也遵循 “主将从现”原则。
u We'll go fishing unless it rains tomorrow.=We'll go fishing if it doesn't rain tomorrow.
假如明天不下雨,我们就去钓鱼。
u 【注意】如果 unless 引导的从句是否定句, 则 unless 不能用 if...not 互换。
n as soon as 的用法
u as soon as 意为 “一……就……”, 引导时间状语从句,等于 “the minute that...”
l 【注意】含 as soon as 的复合句也要遵循“主将从现”原则。
n so/such...that...的用法
u so/such...that... “如此……以至于……”,引导结果状语从句。其中 so修饰形容词或副词, such修饰名词, that后从句为结果。
l 【注意】名词前有much, many, few, little修饰表示程度时,此时用 so 而不用 such。
u 区分so that与so...that...
l “窍门”: “在一起”是 “目的”, “分开”是 “结果”。
