资源简介 2025年人教版(2024)新八年级英语上册精讲精练Unit 8 Let's Communicate!核心语法:连接词的使用一、 核心概念连接词:用来连接词、短语、从句或句子的词,也称为关联词。它们像“胶水”一样,将不同的部分粘合在一起,使表达更流畅、逻辑更清晰。二、 连接词的分类及用法连接词主要分为并列连接词和从属连接词两大类。(一) 并列连接词用于连接平行的、语法功能相同的词、短语或句子。连接词 含义 功能 例句and 和,并且 表示并列、顺接或添加 I like apples and bananas. (我喜欢苹果和香蕉。)but 但是 表示转折或对比 He is rich, but he is not happy. (他很有钱,但不快乐。)or 或者;否则 表示选择;表示否则(常与else连用) Would you like tea or coffee (你要茶还是咖啡?)Hurry up, or (else) you'll be late. (快点,否则你要迟到了。)so 所以,因此 表示结果 It was raining, so we stayed at home. (下雨了,所以我们待在家里。)for 因为 表示原因(语气较弱,不用于句首) She must be ill, for she looks pale. (她一定病了,因为她脸色苍白。)注意:and 和 or 在肯定句和否定句中的用法:肯定句:I like English and math.否定句:I don't like English or math. (在否定句中,连接并列成分通常用 or 代替 and)(二) 从属连接词用于引导一个从句(如状语从句),该从句不能独立存在,需要依附于主句。1. 引导时间状语从句连接词 含义 例句when 当……时候 When I arrived, he was cooking. (我到的时候,他正在做饭。)while 在……期间 While I was reading, he was playing games. (我在看书时,他在玩游戏。)as soon as 一……就…… I'll call you as soon as I get there. (我一到那儿就给你打电话。)before 在……之前 Wash your hands before you eat. (吃饭前要洗手。)after 在……之后 After he finished work, he went home. (他下班后就回家了。)since 自从……以来 I have lived here since I was born. (我自从出生就住在这里。)until / till 直到……为止 I waited until he came back. (我一直等到他回来。)2. 引导原因状语从句连接词 语气强度 例句because 最强 I didn't go to school because I was ill. (我没去上学,因为我病了。)since 次之(既然) Since everyone is here, let's begin. (既然大家都到了,我们开始吧。)as 最弱(由于) As it's raining, we'd better stay indoors. (由于在下雨,我们最好待在室内。)注意:because 回答 why 的问句,语气最强。since 和 as 常放在句首,表示显而易见的原因。3. 引导条件状语从句连接词 含义 例句if 如果 If it rains, we won't go. (如果下雨,我们就不去了。)unless 除非,如果不 You will fail unless you work hard. (你会失败的,除非你努力学习。)核心考点:在条件状语从句和时间状语从句中,要遵守 “主将从现” 原则(主句用将来时,从句用一般现在时表示将来)。4. 引导结果状语从句结构 含义 例句so... that... 如此……以至于…… He is so young that he can't go to school. (他年纪太小,还不能上学。)such... that... 如此……以至于…… It was such a hot day that we all went swimming. (天太热了,我们都去游泳了。)区别:so 后接形容词/副词;such 后接名词或“a/an + 形容词 + 名词”。5. 引导目的状语从句连接词 含义 例句so that 为了,以便 He got up early so that he could catch the first bus. (他早起是为了赶上头班车。)6. 引导让步状语从句连接词 含义 例句though / although 虽然,尽管 Although it was raining, we went out. (尽管下雨,我们还是出去了。)注意:though/although 不能与 but 连用。正:Although he is old, he is strong.误:~~Although he is old, but he is strong.~~三、 易混淆连接词辨析1、because vs. so vs. forbecause 和 so 不能在同一句中连用,它们都表示因果关系,但一个是从属连词,一个是并列连词。误:~~Because he was tired, so he went to bed early.~~正:Because he was tired, he went to bed early. = He was tired, so he went to bed early.for 是并列连词,语气弱,表示推断的理由,不能用于句首。2、when vs. whilewhen 可接延续性或瞬间性动词,从句动作可与主句动作同时或先后发生。while 只能接延续性动词,强调主从句动作同时持续。until 在肯定句和否定句中的用法肯定句(主句动词需是延续性的):I waited until he came. (我等直到他来。)否定句(主句动词需是瞬间性的):I didn't leave until he came. (我直到他来才离开。)1.My bedroom isn’t big, ________ it’s very nice.A.and B.so C.but2.Some food tastes good, ________ it is usually bad for our health.A.so B.but C.and D.or3.—Can you speak English ________ Chinese —I can speak English.A.and B.but C.or D.so4.I know her, __________ I forget(忘记)her name.A.so B.and C.but D.for5.My sister doesn’t like fish, ________ I like fish very much.A.and B.or C.but D.so6.—Judy, you like maths, right —Yes.
