高中选修1冀教版 【语法专版】 A版知识点全解 语法专版 【专题】that/whether引导的宾语从句辨析 高中英语冀教版选修1 考频分析 冀教版选修1中，that/whether引导的宾语从句辨析是重要语法点，考频占从句类语法总量的l5% 左右，主要分布在核心题型：单项选择(12题)、阅读理解（间接考察，影响句意理解）、书面表 达（核心考察，直接影响句子逻辑与准确性）。在语境分析类题目中，连接词的选择及从句陈述/疑 问语气的区分往往是解题关键。 考查内容 。引导词选择：that(陈述句转换，无实际意义)与whether(一般疑问句转换，表“是否”)的基本 区别及适用语境 ·语序规则：从句需用陈述语序（主语在前，谓语在后），避免保留疑问句语序 。特殊用法：whether与f在引导宾语从句时的异同（如与or not连用时只能用whether),及that在 口语或非正式文体中的省略规则 知识点一：that/whether引导的宾语从句辨析 1.hat引导的宾语从句（陈述事实，无疑问含义） 1.语法功能：连接词that无实际意义，仅起连接作用，在从句中不充当成分，常可省略（但并列多个 宾语从句时，第二个及以后的hat不可省略) 2.适用动词：常用于say,think,believe,.know,.hope,tell等表示“陈述/确信”的动词后 3.例句： ·She said(hat)she would come to the party..(省略that,从句陈述事实) ●He told me(that)he had finished the work and that he would go home.(并列从句，第二个that不可 省略) 2.whether引导的宾语从句（表疑问，意为“是否”） 1 高中选修1冀教版 【语法专版】 A版知识点全解 1.语法功能：连接词whether有“是否”的含义，在从句中不充当成分，不可省略：可与or not连用 (whether..or not),也可单独使用 2.适用场景：常用于ask,wonder,.doubt,.decide,.know等表示“疑问/不确定”的动词后；或与介词连 用、位于句首时只能用whether 3.例句： ●I wonder whether she will accept the invitation.(表疑问，是否接受邀请) ·They are discussing whether to go there or not..(与or not连用) ·It depends on whether we have enough money.(与介词on连用) 3.核心区别对比 1.含义不同：that表“陈述事实”，whether表“是否（疑问）” 2.省略规则：that可省略（并列从句除外)，whether不可省略 3.搭配差异：whether可与or not连用/用于介词后，that不可 4.例句对比： ·He believes that she is honest..(that表确信，陈述事实) ●He doubts whether she is honest.(whether表怀疑，是否诚实) 知识点二：that/whether引导的宾语从句辨析 1.功能与适用场景 1.hat引导的宾语从句：用于陈述事实，从句为肯定或否定的陈述句，hat本身无实际意义，常可省 略（但在正式文体或从句较长时建议保留） ·适用动词：say(说)、think(认为)、believe（相信)、know(知道)、hope(希望)、find out(查 明)等 ·例句： 1.She says(hat)she will come to the party.(陈述事实，that可省略) 2.I think(hat)English is interesting..（表达看法，that可省略) 2.whether引导的宾语从句：用于表示“是否”，从句含有疑问含义，常与or not连用（可置于句末或 紧跟whether后)，whether不可省略 ·适用动词：ask(询问)、wonder(想知道)、doubt(怀疑)、decide(决定)、discuss(讨论)等， 或用于介词后、不定式前 。例句： 1.He asks whether she will come to the party(or not).(询问是否，whether不可省略) 高中选修1冀教版 【语法专版】 A版知识点全解 2.I wonder whether it will rain tomorrow or not..(想知道是否，or not置于句末) 3.They are talking about whether to go there by bus.（介词about后用whether,接不定式短语) 2.语序规则（两者通用） 1.宾语从句需用陈述语序（主语+谓语），即无论主句为陈述句还是疑问句，从句均需将疑问词后的 助动词情态动词/系动词移至主语之后 2.错误：She asks whether will he come.(疑问句语序) 3.正确：She asks whether he will come.(陈述语序) 4.例句： 。I know that he has finished his homework.（从句主语he在前，谓语has finished在后) ·He wonders whether she likes the gift.(从句主语she在前，谓语likes在后) 3.时态呼应（两者通用） 1.主句为一般现在时/一般将来时，从句可根据实际情况用任意时态 ·She says(that)she visited Beijing last year.(主句一般现在时，从句一般过去时) ·I will ask whether he is reading now.(主句一般将来时，从句现在进行时) 2.主句为一般过去时，从句需用过去的某种时态（一般过去时、过去进行时、过去完成时、过去将来 时等)，以保持时态一致 ·He thought(that)he could win the game.(主句一般过去时，从句过去将来时could) ·She asked whether they had gone to the park.（主句一般过去时，从句过去完成时) 3.从句表示客观真理、科学事实或永恒不变的规律时，无论主句时态如何，从句均用一般现在时 ●The teacher told us that the earth goes around the sun.(客观真理，从句用一般现在时goes) ●He asked whether water boils at 100C.(科学事实，从句用一般现在时boils) 4.特殊用法对比 1.that的特殊省略情况：当主句谓语动词后接两个或以上并列宾语从句时，第一个从句的that可省略， 第二个及以后的从句that不可省略 ●He said(hat)he was tired and that he wanted to rest.(第二个that不可省略，避免歧义) 2.whether与if的辨析：在引导宾语从句表示“是否”时，whether可用于所有情况，if多用于口语且 不可用于介词后、不定式前或与or not直接连用 ●正确：I'n thinking about whether to buy it.(介词about后用whether) 。错误：I'm thinking about if to buy it..(if不可用于介词后) 3 高中选修1冀教版 【语法专版】 A版知识点全解 ·正确：He doesn't know whether or not to accept the invitation.(whether与or not直接连用) ●错误：He doesn't know if or not to accept the invitation.(if不可与or not直接连用) 知识点三：that/whether引导的宾语从句辨析 1.hat引导的宾语从句 1.基础用法（中考必背）： ●陈述句作宾语，that无意义可省略→例句：She says(hat)she will come tomorrow. 。主句为过去时，从句用相应过去时态→例句：He told me(hat)he bought a new book yesterday. 。表示事实或确定信息→例句：I know(hat)the earth goes around the sun 2.whether引导的宾语从句 1.基础用法（中考必背）： ·一般疑问句作宾语，意为“是否”，不可省略→例句：I wonder whether he will come to the party.. 。常与or not连用→例句：She asked whether we would go by bus or not. 。用于介词后作宾语→例句：We are talking about whether to have a picnic this weekend. 3.辨析与易错点（中考核心） l.选择依据：陈述句用that,疑问句表“是否”用whether→例句：He said(hat)he liked music.(陈 述句)/I don't know whether it will rain.(疑问句) 2.时态一致：主句为现在时，从句用任意时态：主句为过去时，从句用过去相关时态→例句：Se thinks(hat)he is right.(主现从现)/He said(that)he was reading.(主过从过) 3.whether可接不定式，that不可→例句：Ican't decide whether to stay or leave.(正确)/Ican't decide that to stay or leave.(错误) 考法精析 考法一：that/whether引导宾语从句的连接词选择 核心：根据主句动词含义（陈述事实/疑问不确定）及搭配规则（如是否与orot连用、是否位于 介词后)，选择正确连接词that或whether 真题1（语法填空)： She asked_we would have a picnic this weekend. 答案：whether 4 高中选修1冀教版 【语法专版】 A版知识点全解 解析：主句动词asked表“询问”，含疑问含义：从句表“是否周末野餐”，用whether引导 真题2（完形填空）： I believe-hard work leads to success. A.that B.whether C.if D.what 答案：A 解析：主句动词believe表“确信”，陈述事实，用that引导宾语从句：hat无实际意义且可省略，但 此处需选择连接词，故填that 考法二：连接词选择与否定转移综合应用 核心：结合主句动词的情感态度（确信/怀疑）判断连接词that/whether,并正确运用否定转移规则 真题1（语法填空)： I don't think he(know)the truth.He looks so confused. 答案：knows 解析：主句动词think表“认为”，后接that引导的宾语从句(that可省略)：根据否定转移规则，主 句否定(don't think)实则否定从句，从句用肯定形式：主语he为三单，谓语动词用kows。 真题2（单项选择）： She doubts_we can solve the problem in such a short time. A.that B.whether C.if D.what 答案：B 解析：主句动词doubt表“怀疑”，需用whether引导宾语从句表“是否”；if虽可表“是否”，但此 处未出现必须用f的场景，且whether与doubt搭配更符合“不确定”语境，故选B。 考法三：that/whether引导宾语从句的综合运用 核心：结合语境判断从句含义（陈述事实/疑问），掌握连接词选择、省略规则及时态呼应 真题1（单项选择)： She asked meI could help her with her English and-I would have time this weekend. A.if;that B.whether;that C.that;if D.that;whether 答案：B 解析：第一空“asked”表疑问，用whether;第二空为并列宾语从句，第二个连接词不可省略，且 “有时间”表疑问，用that不符合语境，此处“that”错误，正确应为whether,但选项中只有B 符合第一空whether,第二空that虽逻辑稍欠但为给定选项最优解（注：实际并列疑问从句应用 whether..and whether,但初中阶段侧重连接词基本选择)。 真题2（语法填空）： I wonder_(that/whether)he will come to the party.If he comes,please tell me-he will arrive. 5 高中选修1冀教版 【语法专版】 A版知识点全解 答案：whether:that 解析：第一空“wonder”表疑问，用whether;第二空“te”后接陈述事实的宾语从句，用that(可 省略，但语法填空需填连接词)。 解题小妙招 宾语从句连接词妙招 连接词选that或whether,主句动词是关键； 陈述事实用that,疑问不确定用whether: hat可省但不盲目，正式语境或多从句时保留： whether常与or not配，介词之后也用它： if虽表是否意，介词后和or not前要回避： 否定转移需留意，think believe后否定在主句： 形式宾语有it在，真正宾语that从句跟在后。 真题演练 演练一：单项选择试题（共10题） 1.He told me-he would leave for Shanghai next week.
