人教版八年级下册Unit 3单元语法知识梳理与练习 一：单元语法知识梳理 (Unit 3 Growing Up) 一、although引导的让步状语从句 (Adverbial clauses of concession) 【规则变化】 although 意为“虽然；尽管”，用于引导让步状语从句。它可以放在主句之前，也可以放在主句之后。如果放在句首，从句后面通常用逗号与主句隔开。 【易错点】 受汉语“虽然……但是……”的思维影响，很多同学容易在英文中将 although（或 though）与 but 连用。注意：在同一个英语句子中，though / although 与 but 绝对不可同时使用。 【例句】 Although you argued, you are still very close friends. 尽管你们争吵过，你们仍然是非常亲密的朋友。 Although my guitar is old, it means a lot to me. 虽然我的吉他很旧了，但它对我意义重大。 二、until引导的时间状语从句 (Adverbial clauses of time) 【规则变化】 until 意为“直到……为止”，用于引导时间状语从句。 1. 当主句的谓语动词是延续性动词（如 wait, stay, sleep 等）时，肯定句表示动作一直延续到 until 所表示的时间为止。 2. 当主句的谓语动词是非延续性动词（如 start, go, leave, talk 等）时，通常用否定式 not ... until ...，意为“直到……才……”。 【注意】 在 until 引导的时间状语从句中，通常要遵循“主将从现”的原则，即主句是一般将来时，从句用一般现在时表示将来。 【例句】 You won't know how he feels until you talk to him. 直到你和他谈谈，你才会知道他的感受。 I couldn't talk about my feelings to anybody until you sat with me during lunch that day. 直到那天午餐时你坐在我身边，我才能够对别人倾诉我的感受。 三、so that引导的目的状语从句 (Adverbial clauses of purpose) 【规则变化】 so that 意为“为了；以便”，用于引导目的状语从句。 【注意】 so that 引导的从句中，通常会含有情态动词如 can, could, may, might, will, would, should 等。它表示某人做某事是为了达到某种目的。 【拓展】 so that 也可以引导结果状语从句，此时意为“因此，结果是”，从句中往往不含有情态动词。注意与 so...that...（如此……以至于……）进行区分。 【例句】 You can write to your parents so that they'll know how you feel. 你可以给父母写信，以便他们了解你的感受。 Mrs Thompson listened to me and talked with me so that I felt much better. 汤普森老师倾听我的心声并与我交谈，因此我感觉好多了。 二：单元语法知识练习 I. 单项选择（10道） 1. _____ it was raining hard outside, the students still went out to practice football.
