(并列) 例：Open the window and let in some fresh air. (顺承/结果) 例：He is a teacher and a father. (对比) 2. but：表示转折、对比。 例：He is poor but happy. (转折) 例：I like apples but he prefers oranges. (对比) 3. or：表示选择；用于否定句中连接并列成分，表示“和”；有时表示警告或威胁。 例：Would you like tea or coffee? (选择) 例：He doesn't know or care about it. (否定句中的“和”) 例：Hurry up, or you will miss the train. (警告) 4. so：表示结果。 例：It was late, so we went home. (结果) 5. for：表示原因（常放在句末，前有逗号，语气不如 because 强）。 例：He must be ill, for he is absent today. (原因) 6. nor：用于否定句之后，表示“也不”。常与 neither 连用 (neither...nor...)。 例：He didn't go, nor did he know anything about it. 例：She can neither sing nor dance. (连接两个并列的动词短语) 7. yet：表示转折，语气比 but 弱。 例：It's strange yet true. (转折) 注意： 连接三个或三个以上并列成分时，通常用逗号加 and (or/but)。 例：I bought apples, oranges, pears, and bananas. 【即时训练】 1. He likes playing basketball, ________ he doesn't play very often. A. and B. but C. or D. so 【答案】B 【解析】考查并列连词。句意：他喜欢打篮球，但是他打得不是很频繁。前后两个分句之间是转折关系，“喜欢”和“不常打”形成对比，因此用表示转折的并列连词 but。and 表示并列，or 表示选择，so 表示结果，均不符合句意。故选 B 项。 2. She is very busy today, ________ she will call you later. A. and B. but C. or D. so 【答案】D 【解析】考查并列连词。句意：她今天很忙，所以她稍后会给你打电话。前一分句说明原因（很忙），后一分句说明结果（稍后打电话），因此用表示因果关系的并列连词 so。and 表示并列，but 表示转折，or 表示选择，均不符合句意。故选 D 项。 3. You can watch TV, ________ you can read a book. Both are good ways to relax. A. and B. but C. or D. so 【答案】A 【解析】考查并列连词。句意：你可以看电视，你也可以读书。两者都是放松的好方法。前后两个分句表示两种并列的选择或活动，并且后面的句子也表明两者都是可以的，因此用表示并列关系的并列连词 and。but 表示转折，or 表示选择（但通常用于两者选其一的语境，这里强调两者皆可），so 表示结果，均不符合句意。故选 A 项。 4. Please turn off the lights ________ close the windows before you leave. A. and B. but C. or D. so 【答案】A 【解析】考查并列连词。句意：离开之前请关掉灯并关上窗户。前后两个分句是两个需要同时完成的动作，表示并列关系，因此用并列连词 and。but 表示转折，or 表示选择，so 表示结果，均不符合句意。故选 A 项。 5. Be quick, ________ you will miss the bus. A. and B. but C. or D. so 【答案】C 【解析】考查并列连词。句意：快点，否则你会错过公交车。前一分句提出一个要求或建议（快点），后一分句说明不这样做可能带来的后果（错过公交车），这种“祈使句 + or + 陈述句”的结构常用来表示警告或提醒，or 意为“否则”。and, but, so 均不符合这种特定结构。故选 C 项。 6. He didn't study hard, ________ he failed the exam. A. and B. but C. or D. so 【答案】D 【解析】考查并列连词。句意：他没有努力学习，所以他考试不及格。前一分句说明原因（没努力学习），后一分句说明结果（考试不及格），因此用表示因果关系的并列连词 so。and 表示并列，but 表示转折，or 表示选择或“否则”，均不符合句意。故选 D 项。 7. You can either go by bus ________ take a taxi. It's up to you. A. And B. but C. or D. so 【答案】C 【解析】考查并列连词。句意：你可以选择乘公交车或者打车。由你决定。前后两个分句提供了两种互斥的选择，表示选择关系，因此用并列连词 or。either...or... 是固定搭配，表示“要么...要么...”。and 表示并列，but 表示转折，so 表示结果，均不符合句意。故选 C 项。 8. The weather is nice today; ________ we are going to have a picnic in the park. A. And B. but C. or D. so 【答案】A 【解析】考查并列连词。句意：今天天气很好；我们打算去公园野餐。分号前后是两个独立的句子，但它们之间是顺承或并列关系（天气好，所以去野餐，但这里用 and 更侧重于陈述两个事实或计划），因此用并列连词 and 连接。but 表示转折，or 表示选择，so 虽然也有因果意味，但 and 在连接由分号隔开的并列句时更常见，尤其是在陈述两个相关事实时。故选 A 项。（注：这里 so 也有一定道理，但 and 更侧重并列陈述，so 更侧重因果，根据语境，and 更符合“天气好，我们计划去野餐”这种陈述两个相关事实的感觉。） 9. I want to buy a new computer, ________ I don't have enough money right now. A. and B. but C. or D. so 【答案】B 【解析】考查并列连词。句意：我想买一台新电脑，但是我目前没有足够的钱。前一分句表达一个愿望，后一分句说明一个与之相反的现实情况，两者之间是转折关系，因此用表示转折的并列连词 but。and 表示并列，or 表示选择，so 表示结果，均不符合句意。故选 B 项。 10. Open the window ________ let some fresh air in. A. And B. but C. or D. so 【答案】A 【解析】考查并列连词。句意：打开窗户并让一些新鲜空气进来。前后两个分句是两个相关联的动作，表示目的或顺承关系，因此用并列连词 and 连接。but 表示转折，or 表示选择，so 表示结果，均不符合句意。故选 A 项。 【知识点清单二】从属连词 (Subordinating Conjunctions) 【要点精讲】 引导从句（名词性从句、定语从句、状语从句），从句在句子中充当某个成分。 1. 引导时间状语从句： when, while, as, before, after, since, till, until, as soon as, once, the moment/instant/day/minute..., every time... 例：I was reading when he came in.

(表示时间先后，用 after) 2. because 和 so 的连用： 因为...所以...不能同时用 because 和 so 连接两个句子，只能用其中一个。 错误：He was late because the bus broke down, so the teacher was angry. 正确：He was late because the bus broke down. / The bus broke down, so he was late. 3. though/although 与 but 的连用： 表转折时，though/although 和 but 不能同时使用，只能选其一。 错误：Although it rained heavily, but they still went out. 正确：Although it rained heavily, they still went out. / It rained heavily, but they still went out. 4. till/until 的用法： 主句用肯定式，表示“直到...才...”； 主句用否定式，表示“在...之前不...”或“直到...才...”。 例：Wait till I call you. (肯定) 例：He didn't leave until midnight. (否定) 5. so...that... 与 such...that... 的区别： so + adj./adv. + that + 从句 such + a/an + adj. + 单数可数名词 + that + 从句 such + adj. + 复数可数名词 + that + 从句 such + adj. + 不可数名词 + that + 从句 例：He spoke so quickly that I couldn't follow him. 例：It was such a hot day that we went swimming. 例：He made such mistakes that he failed the exam. 6. whether...or... 与 either...or... 的区别： whether...or... 表示“是...还是...（在两者之间选择，有时含不确定性）”，引导让步状语从句或名词性从句。 either...or... 表示“或者...或者...（两者选其一）”，连接并列成分。 例：Whether you like it or not, you have to do it.

But 【答案】A 【解析】考查连词辨析。句意：尽管下大雨了，我们还是非常享受野餐。前后两个分句之间是让步关系，尽管有下雨这个不利条件，但仍然享受野餐。although 引导让步状语从句。because 引导原因状语从句，so 是并列连词表示结果，but 是并列连词表示转折，都不能直接放在句首引导从句并表达这种让步关系。故选 A 项。（易错点：混淆 although 和 because 的用法，以及不同连词引导从句的能力）。 5. She is not only beautiful _______ clever. A. and B. but C. or D. so 【答案】B 【解析】考查固定搭配。句意：她不仅漂亮而且聪明。not only... but also... 是固定搭配，表示“不仅...而且...”，连接并列成分。虽然 also 常常省略，但 but 是必不可少的。and, or, so 都不能与 not only 搭配构成此意。故选 B 项。（易错点：忘记 not only... but also... 这个固定搭配，或者误用其他连词）。 6. You must hurry up, _______ you will miss the train. A. and B. but C. or D. so 【答案】C 【解析】考查连词辨析。句意：你必须快点，否则你会错过火车。前后两个分句之间隐含着一种选择关系，要么快点，要么就错过火车（不快点的结果）。or 在这里表示“否则，要不然”，相当于 otherwise。and 表示并列，but 表示转折，so 表示结果，均不符合。故选 C 项。（易错点：不理解 or 在特定语境下表示“否则”的用法）。 7.

Because B. so C. but D. and 【答案】A 【解析】考查连词辨析。句意：他上学迟到了，因为公共汽车抛锚了。前后两个分句之间是因果关系，前一分句是结果（迟到），后一分句是原因（车坏了）。because 引导原因状语从句。so 引导结果状语从句（通常结构是原因，so 结果），but 表示转折，and 表示并列，均不符合。故选 A 项。（易错点：混淆 because 和 so 的引导能力，以及句子结构是“结果，because 原因”还是“原因，so 结果”）。 8. _______ you study hard, _______ you will pass the exam. A. Because; so B. So; that C. If; then D. Although; but 【答案】C 【解析】考查连词辨析。句意：如果你努力学习，你就会通过考试。前后两个分句之间是条件关系，前者是条件（努力学习），后者是可能产生的结果。if 引导条件状语从句，then 常常与 if 连用，表示“那么”。Because 和 so 不能这样搭配使用。so that 引导结果状语从句，但结构不同。although 不能与 but 连用。故选 C 项。（易错点：混淆不同从句的引导词及其搭配，如 if...then..., because...so... 的错误搭配）。 9. This book is _______ interesting _______ I read it again. A. too; to B. so; that C. such; that C. enough; to 【答案】B 【解析】考查固定搭配。句意：这本书如此有趣，以至于我又读了一遍。so...that... 是固定搭配，表示“如此...以至于...”。so 修饰形容词或副词。such...that... 也是固定搭配，但 such 修饰名词（such a/an+adj.+单数可数名词 / such adj.+复数名词/不可数名词）。这里 interesting 是形容词，所以用 so。故选 B 项。（易错点：混淆 so...that... 和 such...that... 的用法，尤其是修饰对象的区别）。 10. He is tired _______ hungry after the long walk. A. and B. but C. or D. so 【答案】A 【解析】考查并列连词。句意：长途步行之后，他又累又饿。这里 tired 和 hungry 是并列的两个形容词，共同修饰主语 he，表示他处于这两种状态。and 连接并列的形容词、名词、动词等。but 表示转折，or 表示选择，so 表示结果，均不符合。故选 A 项。（易错点：忘记 and 可以连接并列的形容词或其他成分来修饰同一个词）。 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$ 编写说明：2026版内蒙古自治区（对口招生）一轮复习《英语知识点清单》，依据最新的《中等职业学校英语课程标准》及历年高考真题进行编写。本资料将高考必备知识进行科学划分，系统总结归纳知识点，全面梳理高考题型。本专辑共三大部分：第一部分是按照基础语法知识点编写的语法知识清单，第二部分是针对课程标准和高考真题中高频词汇和句型的语言知识清单，第三部分是依据各个高考题型编写的题型技巧清单。每份资料均配备配套讲义和练习题。 本专题是2026版内蒙古自治区（对口招生）一轮复习《英语知识点清单》中语法知识清单的第7个专题，内容为连词。 内蒙古2026年对口招生考试一轮复习 英语语法知识清单 专题7 连词（讲+练） 【考点解读】 通过近三年的内蒙古中职高考试题可以看出，连词的考点主要考查各类连词的掌握程度。重点在于能否根据句子结构和具体语境，准确判断需要使用哪种连词来连接词、短语或句子，并理解其表示的逻辑关系。同时，要能够正确区分形近或义近的连词。这部分内容是构建复杂句子的基础，需要学生多积累、多对比、多练习。 连词是一种虚词，不能独立担任句子成分，但能连接词、短语、从句和句子，表示它们之间的各种关系（如并列、转折、因果、条件、时间、让步等）。 【知识点清单一】并列连词 (Coordinating Conjunctions) 【要点精讲】 连接地位平等的词、短语或句子。常用并列连词有：and, but, or, so, for, nor, yet。 1. and：表示并列、添加、顺承、结果或对比。 例：He is smart and hard-working.

(原因在前，用 because) 或 He didn't go to school because he was ill. (原因在后，用 because) 错误：And he finished his homework, he went out to play. 正确：After he finished his homework, he went out to play. (表示时间先后，用 after) 2. because 和 so 的连用： 因为...所以...不能同时用 because 和 so 连接两个句子，只能用其中一个。 错误：He was late because the bus broke down, so the teacher was angry. 正确：He was late because the bus broke down. / The bus broke down, so he was late. 3. though/although 与 but 的连用： 表转折时，though/although 和 but 不能同时使用，只能选其一。 错误：Although it rained heavily, but they still went out. 正确：Although it rained heavily, they still went out. / It rained heavily, but they still went out. 4. till/until 的用法： 主句用肯定式，表示“直到...才...”； 主句用否定式，表示“在...之前不...”或“直到...才...”。 例：Wait till I call you. (肯定) 例：He didn't leave until midnight. (否定) 5. so...that... 与 such...that... 的区别： so + adj./adv. + that + 从句 such + a/an + adj. + 单数可数名词 + that + 从句 such + adj. + 复数可数名词 + that + 从句 such + adj. + 不可数名词 + that + 从句 例：He spoke so quickly that I couldn't follow him. 例：It was such a hot day that we went swimming. 例：He made such mistakes that he failed the exam. 6. whether...or... 与 either...or... 的区别： whether...or... 表示“是...还是...（在两者之间选择，有时含不确定性）”，引导让步状语从句或名词性从句。 either...or... 表示“或者...或者...（两者选其一）”，连接并列成分。 例：Whether you like it or not, you have to do it. (让步) 例：I don't know whether he will come or not. (宾语从句) 例：You can have either tea or coffee. (选择) 【即时训练】 1. She didn't come to school yesterday, _______ she was ill. A. because B. so C. but D. and 2.
