Unit 2　Why don’t you talk to your parents？
Section A (Grammar Focus-4c)
语法精讲细练
【语法解读】
1. until意为“直到”, 引导时间状语从句
(1)当主句是肯定句时, 主句中的谓语动词必须是延续性动词。
(2)not. . . until. . . 意为“直到……才……”, 主句的谓语动词一般是非延续性动词, 它所表示的动作直到所表示的时间才发生。
(3)如果主句为一般将来时, 从句要用一般现在时表示将来。
2. although
although是连词, 意思是“虽然, 尽管”, 引导让步状语从句, 可以放在主句前面, 也可以放在主句后面。
【警示】
在一个句子中, 用了 although就不能再用but, 但可用yet; 用了 but 就不能用 although。
3. so that
(1)so that意为“以便; 为了”, 常用来引导目的状语从句, 一般放在主句后, 且不用逗号隔开。目的状语从句常表示动机(即一种可能性), 因此从句中常带有can, could, would, should等情态动词。
(2)当so that引导的从句的主语和主句主语一致时, 可用in order to 或不定式短语替换, 其意义基本不变。
