A. and B. or C. but D. so 10.___ you like it or not, you have to finish it on time. A. If B. Whether C. Although D. When 二、用适当的连词填空 1.Study hard, ___ you will pass the test. 2.___ you don't like the movie, we can go to the park instead. 3.He is tired, ___ he still keeps working. 4.I want to buy a shirt, ___ I don't know the size. 5.You can take a bus ___ take a taxi to get there. 6.___ the weather is fine, we will have a picnic tomorrow. 7.She didn't go to school ___ she was ill. 8.Please wait ___ I come back. 9.I like both apples ___ bananas. 10.___ he finished his homework, he watched TV. 三、改错(每句一处错误) 1.Although he is poor, but he is happy. 2.Hurry up, and you will be late. 3.Either you or he are wrong. 4.She was reading when her mother was cooking. 5.Because he was ill, so he didn't go to school. 【知识点清单二】高频考点及解题策略 一、高频考点 1. 逻辑关系辨析:转折 vs. 因果 vs. 并列: 关系 连词 举例 句中出现 “但是、然而” 等含义, but/however He tried hard, but he failed.(转折) 表 “因此、所以” so/therefore He worked hard, so he passed the exam.(因果) 表 “并且、和” and She likes singing and dancing.(并列) 2.祈使句 + or /and+ 分句 ,此句型简洁明确地表达 “行为与后果” 的因果关系。 句型 含义 用法或替换 例句 动词原形开头的祈使句 + or + 含将来后果的陈述句 or 意为 “否则;不然”,隐含 “如果不做祈使句动作,就会导致分句结果” 的逻辑。 or 可换为 otherwise(较正式) Hurry up, or you’ll miss the bus. (快点,否则你会错过公交。) 隐含:If you don’t hurry up, you’ll miss the bus. 否定祈使句Don’t play with fire, or you may get burned.(别玩火,否则可能会烫伤。) Be on time, otherwise the meeting will start without you.(准时到,否则会议会不等你开始。) 祈使句 + and + 分句 表 “做某事,就会有好结果”, 相当于 “if...will...” Study hard, and you’ll get good grades. (努力学习,你就会取得好成绩。) 注意:分句常用 will + 动词原形(一般将来时);祈使句与分句间必须用 逗号 分隔。 3. 固定搭配与句型 句型 用法 例句 both...and...(两者都) 连接并列主语时,谓语用复数。 Both Tom and Lily are students. either...or.../neither...nor...(要么… 要么…/ 既不… 也不…) 遵循就近原则 Either you or he is wrong.(就近主语 he 为单数,用 is) not only...but also...(不仅… 而且…) 遵循就近原则,可连接并列主语、谓语、宾语等 Not only you but also I am interested in art.(就近主语 I 用 am) 4. 状语从句的时态规则 时态 用法 例句 主将从现 条件 / 时间状语从句中,主句用将来时,从句用一般现在时 I will call you when he arrives.(when 从句用 arrives,主句用 will call) 过去进行时 + 一般过去时 when/while 引导的时间状语从句中,若强调 “过去某时刻正在进行的动作”,主句用过去进行时,从句用一般过去时。 While she was cooking, the phone rang.(从句用过去进行时,主句用一般过去时) 5. 易混连词辨析 易混连词 用法 例句 because vs. since/as/for because:直接原因,回答 why,可置于句首或句中。 不和so连用。 Because it is raining, we stay at home. since/as:“既然 / 由于”,语气较弱,引导已知原因,置于句首。 Since you are free, you can help me. for:补充说明原因,不可置于句首,用逗号与主句隔开。 He must be at home, for the light is on. although vs. but 两者不可连用,只能选其一。 Although he is poor, he is happy. 或 He is poor, but he is happy. if vs. whether if:引导条件状语从句(“如果”)或宾语从句(“是否”,但不可与 or not 连用)。 I don’t know if/whether he will come.(宾语从句,两者均可) whether:引导宾语从句(“是否”),可与 or not 连用,或用于介词后。 I will go whether it rains or not.(不可用 if) 二、解题步骤与技巧 1.分析句子结构 确定是并列句还是复合句,判断连词类型(并列连词 / 从属连词)。 2.判断逻辑关系 根据上下文,确定句子间的逻辑关系(转折、因果、条件、时间等) 3.熟记固定搭配 如 either...or..., neither...nor..., so...that... 等,直接根据搭配选择 4.排除法 若对选项不确定,先排除明显不符合逻辑或语法的选项,缩小范围。 三、典型错误与规避 易错 误用 正确 混用 but 和 although。 Although he is old, but he is strong. Although he is old, he is strong. 或 He is old, but he is strong. 忽略主将从现原则。 If it will rain tomorrow, we will stay at home. If it rains tomorrow, we will stay at home.(从句用一般现在时) 就近原则使用错误。 Neither you nor he are right. Neither you nor he is right.(就近主语 he 为单数) 四、总结:连词是英语中构建句子逻辑的关键,核心考点集中在: 1.并列连词的逻辑关系(and/but/or/so)及固定搭配; 2.从属连词引导的状语从句(时间、条件、原因、让步等)及时态规则; 3.宾语从句引导词(that/if/whether/ 特殊疑问词)的选择; 4.主谓一致(如就近原则)在并列结构中的应用。 【即时训练】 一、并列连词易错题 1. 转折与结果混淆 He worked hard, ___ he failed the exam. A. and   B. but   C. so   D. or 2. or 的双重含义(选择 / 否则) Hurry up, ___ you’ll be late. A. and   B. or   C. so   D. but 3. 固定搭配误用 ___ you ___ he is right. A. Both; and  B. Either; or  C. Neither; or  D. Not only; but 二、从属连词易错题 1. 条件状语从句:if vs. unless You won’t pass the exam ___ you study hard. A.if  B. unless   C. when  D. because 2. 让步状语从句:although vs. but ___ he is old, but he is strong. A. Although  B. But  C. Because  D. So 3. 时间状语从句:when vs. while I was reading ___ my mother was cooking. A.when  B. while  C. until  D. since 三、复合连词易错题 1. 因果关系:because vs. so 改错: Because he was ill, so he didn’t go to school. 2. 并列与递进:and vs. or vs. but Would you like tea ___ coffee? A. and  B. or  C. but  D. so 3. 逻辑关系判断错误 She is very tired, ___ she still keeps working. A. and  B. so  C. but  D. or 四、易错题总结与对策 1.避免中文直译:英语中 although/but、because/so 不可连用,需牢记逻辑关系词的唯一性。 2.区分连词功能:并列连词(and/or/but/so)连接并列成分,表顺承、选择、转折、因果。 从属连词(if/although/when)引导从句,需注意从句类型(条件、让步、时间等)。 3.主谓一致陷阱:含 either...or.../neither...nor.../not only...but also... 的句子,谓语动词遵循 “就近原则”。 4.语境逻辑分析:做题时先判断前后句逻辑(转折、因果、条件、时间等),再选择对应连词。 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:黑龙江省2026年春季高考一轮复习《英语知识点清单》,依据《中等职业学校英语课程标准》(2020年版)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、课件和练习题。 本专题是黑龙江省2026年春季高考一轮复习《英语知识点清单》中语法知识清单的第6个专题,内容为连词。 黑龙江省2026年春季高考一轮复习 英语语法知识清单 专题6 连词(讲+练)【考点解读】 近三年真题显示,连词考点主要分并列连词和从属连词。并列连词表并列、转折、选择等关系,如 and、but、or,需注意固定搭配(如 both...and...)和主谓一致(如 neither...nor... 就近原则)。从属连词引导从句,时间状语从句(when/while)、条件状语从句(if/unless)需注意时态(主将从现),让步状语从句(although/though)不可与 but 连用。宾语从句中,that 可省略,if/whether 表 “是否”(whether 可接 or not)。解题需分析逻辑关系,熟记搭配及时态规则。(从属连词多放在从句中理解并应用。) 连词综述 连词是连接词、短语、从句或句子的词,分为 并列连词 和 从属连词,两者在句子结构和逻辑关系中承担不同功能。此章重点是并列连词。 【知识点清单一】连词的分类 1. 并列连词(连接并列成分或句子):常用连词 连词 功能 常考搭配 / 考点 and 表并列、顺承或递进 固定搭配:both...and...(两者都) but 表转折(对比或意外) 易混辨析:but /however(后者为副词,需标点) or 表选择(肯定句)或否定条件(否定句) 固定搭配:either...or...(要么… 要么…) so 表结果(因果关系) 易混辨析:so /so that(后者引导目的状语从句) for 表原因(补充说明) 与 because 的区别:for 不可置于句首 nor 表否定并列(常与 neither 连用) 固定搭配:neither...nor...(既不… 也不…) 2.区分连词 关系 连词 例句 并列关系 and(和):连接两个并列成分,有时表顺承 Go straight and you’ll see the shop。 as well as(也):强调前者,谓语动词与前一主语一致 He as well as I likes reading。 both...and...(两者都):连接并列主语时,谓语用复数 Both you and I are students。 转折关系 but(但是):直接转折 I want to go, but I’m busy。 however(然而):用逗号隔开,语气更缓和 I like it; however, it’s too expensive。 while(而):对比两者差异 He is tall, while she is short。 选择关系 or(或者;否则):表选择或警告 Hurry up, or you’ll be late。 either...or...(要么… 要么…):就近原则 Either you or he is wrong。 neither...nor...(既不… 也不…):就近原则 Neither she nor I am a teacher。 因果关系 so(所以):直接结果 It’s raining, so we stay at home for(因为):补充说明原因 He must be ill, for he didn’t come。 典型例题: 并列转折:I wanted to go hiking, but it rained heavily.(我想去徒步,但雨下得很大。) 选择结构:You can either stay at home or go to the cinema with us.(你要么待在家里,要么和我们去看电影。) 否定并列:Neither he nor I am interested in playing video games.(他和我都对玩电子游戏没兴趣。) ▶ 考点:neither...nor... 遵循就近原则,谓语动词与靠近的主语(I)一致,用 am。 2.从属连词 从属连词(引导从句,如状语从句、宾语从句等) 1)引导状语从句的从属连词 从句类型 常用连词 核心考点 时间状语从句 when, while, as, before, after, until, since when/while 的区别:when 接瞬间 / 延续性动作;while 接延续性动作(从句用进行时) not...until...(直到… 才…) 条件状语从句 if, unless, as long as, in case 遵循 “主将从现” 原则(主句将来时,从句一般现在时) unless=if...not(除非) 原因状语从句 because, since, as, for because 回答 why 问句;since/as 表 “既然 / 由于”(语气较弱) for 表补充原因(不可置于句首) 让步状语从句 although, though, even if, even though although/though 不可与 but 连用 even if(即使)表假设,引导虚拟语气 目的状语从句 so that, in order that 从句中常含 can/may/will 等情态动词 结果状语从句 so...that..., such...that... so + 形容词 / 副词;such + 名词短语 典型例题: 时间状语从句:While she was reading, I cooked dinner.(她读书时,我在做晚饭。) ▶ 考点:while 引导的从句用延续性动作,常用进行时。 条件状语从句:You won’t pass the exam unless you study hard.(除非你努力学习,否则考不及格。) ▶ 考点:unless=if you don’t study hard,注意否定转换。 结果状语从句:It was such a hot day that we all stayed indoors.(天气太热,我们都待在屋里。) ▶ 考点:such+a/an + 形容词 + 单数名词 + that... 2)引导宾语从句的从属连词 类型 连词 用法 陈述句 that(可省略) I think (that) he is right.(我认为他是对的。) 一般疑问句 if/whether(是否) Do you know if/whether she will come?(你知道她是否会来吗?) 特殊疑问句 特殊疑问词(what, how, why 等) Can you tell me where he lives?(你能告诉我他住哪里吗?) 2典型例题: 宾语从句引导词:I wonder whether he likes coffee or tea.(我想知道他喜欢咖啡还是茶。) ▶ 考点:whether 可与 or not 连用(whether or not),if 不可。 【即时训练】 一、单项选择 1.Work hard, ___ you will fail the exam.

A. and   B. but   C. so   D. or 易错点:误选 C(so 表结果),忽略前后逻辑为转折。 解析:“努力” 与 “失败” 是转折关系,应选 B. but。 陷阱:中文思维可能认为 “努力所以失败” 表因果,但英语中需根据实际逻辑判断。 2. or 的双重含义(选择 / 否则) Hurry up, ___ you’ll be late. A. and   B. or   C. so   D. but 易错点:未区分 or 作 “否则”(祈使句结构)和 “或者”(选择)的用法。 解析:祈使句 + or + 否定结果,表 “否则”,选 B. or。 对比:You can stay at home or go out.(选择,用 or) 3. 固定搭配误用 ___ you ___ he is right. A. Both; and  B. Either; or  C. Neither; or  D. Not only; but 易错点: 忽略主谓一致(就近原则)。 混淆搭配:neither 应与 nor 连用,not only 与 but also 连用。 解析:谓语动词是 is(单数),需用就近原则的搭配,选 B. Either; or。 陷阱:C 项 neither; or 搭配错误,应为 neither; nor。 二、从属连词易错题 1. 条件状语从句:if vs. unless You won’t pass the exam ___ you study hard. A.if  B. unless   C. when  D. because 易错点: 误选 A(if),未理解 “除非努力,否则不及格” 的逻辑。 unless=if not,需转换为肯定句理解。 解析:“如果不努力就不及格”,选 B. unless。 公式:unless + 肯定句 = if + 否定句(You won’t pass if you don’t study hard.) 2. 让步状语从句:although vs. but ___ he is old, but he is strong. A. Although  B. But  C. Because  D. So 易错点: 中文 “虽然… 但是…” 的惯性表达,导致误用 although 和 but 连用。 解析:英语中 although 与 but 不能同时出现,应删去其中一个,正确表达为: Although he is old, he is strong. 或 He is old, but he is strong. 答案:原题错误,需修改连词,此处选 A. Although 时需删去 but。 3. 时间状语从句:when vs. while I was reading ___ my mother was cooking. A.when  B. while  C. until  D. since 易错点: when 可接延续 / 非延续动作,while 仅接延续性动作。 两句均为进行时(延续动作),需用 while。 解析:两个动作同时持续进行,选 B. while。 对比:I was reading when the phone rang.(when 后接非延续动作 rang) 三、复合连词易错题 1. 因果关系:because vs. so Because he was ill, so he didn’t go to school. 易错点: 中文 “因为… 所以…” 的搭配导致误用,英语中 because 与 so 不可连用。 解析:删去其中一个连词,正确表达为: Because he was ill, he didn’t go to school. 或 He was ill, so he didn’t go to school. 2. 并列与递进:and vs. or vs. but Would you like tea ___ coffee? A. and  B. or  C. but  D. so 易错点:疑问句中表选择用 or,而非 and(肯定句中表并列)。 解析:询问 “茶或咖啡”,选 B. or。 对比:I like tea and coffee.(肯定句中用 and 表两者都喜欢) 3. 逻辑关系判断错误 She is very tired, ___ she still keeps working. A. and  B. so  C. but  D. or 易错点:误判为因果关系(选 so),实际为转折关系(“累但继续工作”)。 解析:转折关系选 C. but。 四、易错题总结与对策 1.避免中文直译:英语中 although/but、because/so 不可连用,需牢记逻辑关系词的唯一性。 2.区分连词功能:并列连词(and/or/but/so)连接并列成分,表顺承、选择、转折、因果。 从属连词(if/although/when)引导从句,需注意从句类型(条件、让步、时间等)。 3.主谓一致陷阱:含 either...or.../neither...nor.../not only...but also... 的句子,谓语动词遵循 “就近原则”。 4.语境逻辑分析:做题时先判断前后句逻辑(转折、因果、条件、时间等),再选择对应连词。 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 $$
