2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ 2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ 学校:___________姓名：___________班级：___________考号：___________ Unit 5 Looking into nature 单元Grammar：that、if、whether引导的宾语从句易错题精练60题   语   法   精   讲 一、基本概念 1.宾语从句定义：在句中作及物动词 / 介词 / 形容词的宾语，由连接词引导的名词性从句 2.三类引导词共性：连接主句和从句，无实在意义（if/whether 表 “是否” 除外），不充当从句成分 二、that 引导的宾语从句 1. 适用情况 主句谓语为陈述类及物动词：say, tell, think, believe, know, hope, find, feel 等 从句为陈述句（表达事实、观点、陈述） 2. 核心用法 that 无词义，不充当从句成分，可省略（主句谓语后直接接从句时） 特例：并列宾语从句中，第二个及以后的 that不可省略（如 He said (that) he was late and that he was sorry.） 3. 例句 I think (that) English is easy. She told me (that) she would go to Beijing. 三、if/whether 引导的宾语从句 1. 适用情况 主句谓语为疑问类及物动词：ask, wonder, want to know, check, find out 等 从句为一般疑问句（表达疑问、不确定） 2. 核心共性 均表 “是否”，无其他词义，不充当从句成分 从句需用陈述语序（主谓不倒装，无助动词提前） 3. 例句（通用） He asks if/whether I like reading. I wonder if/whether it will rain tomorrow. 四、if vs whether 用法区别（重点） 1. 可互换场景（大多数情况） 主句后直接接从句，从句无其他附加成分：Do you know if/whether she is here? 2. 只能用 whether 的场景（必考） 1.从句后接or not：I don’t know whether or not he will come.（if 不可接 or not） 2.作介词的宾语：It depends on whether it is fine tomorrow.（介词后不用 if） 3.后接不定式 to do：She hasn’t decided whether to go or stay.（if 无此用法） 4.引导的从句作主语 / 表语（宾语从句延伸，初中常考）：Whether he will come is unknown. 5.放在句首表疑问：Whether we will go camping hasn’t been decided. 五、三类宾语从句通用规则（时态 / 语序 / 人称） 1. 语序规则（重中之重） 所有宾语从句一律用陈述语序：引导词 + 主语 + 谓语 + 其他 错误：Do you know if is she a student? → 正确：Do you know if she is a student? 2. 时态规则 1.主句为一般现在时 / 一般将来时：从句用任意所需时态（根据句意） I know that he lives here.（现） I will ask if he went to school yesterday.（过） 1.主句为一般过去时：从句用相应过去时态（过去时 / 过去进行 / 过去完成 / 过去将来） She said that she was busy.（一般过去） He asked if I had finished my homework.（过去完成） 1.特例：从句表客观真理 / 客观事实：无论主句时态，从句一律用一般现在时 The teacher said that the earth goes around the sun. 3. 人称规则 从句人称根据句意逻辑调整，与主句主语 / 宾语保持一致 例句：He asked me, “What is your name?” → He asked me what my name was. 六、易错点总结 1.that 省略：并列从句中不可省，单独从句可省，勿漏省 / 多省 2.语序错误：避免把疑问句语序直接带入从句 3.if/whether 误用：牢记 only whether 的 5 种场景 4.时态呼应：主句过去时，从句需变相应过去时（客观真理除外） 5.标点：宾语从句为陈述句，句末用主句的标点，从句内部不加标点   语   法   精   练 一、单项选择 1．We haven’t decided ________ we will go on a picnic this weekend. A．until B．whether C．since D．unless 【答案】B 【详解】句意：我们还没有决定这个周末是否去野餐。 考查宾语从句引导词。until直到；whether是否；since因为，自从；unless除非。根据“We haven’t decided ...”可知，此处用whether引导宾语从句，表示“是否”，强调对选择的不确定性。故选B。 2．—I hope ________ the driving test.   —I hope so. Thank you. A．you will pass B．you to pass C．to passing D．passing 【答案】A 【详解】句意：——-我希望你会通过驾驶考试。——-希望如此。谢谢你。 考查hope的用法。you will pass你会通过；you to pass你通过；to passing通过，介词to后跟动名词形式；passing通过，动名词。hope意为“希望”，动词，有“hope to do希望做某事”或者“hope+从句”两种用法，此处为“hope+that省略的宾语从句”，故选A。 3．I believe ________ sport events can build our character. A．when B．why C．how D．that 【答案】D 【详解】句意：我相信体育赛事能够塑造我们的品格。 考查宾语从句的引导词。when何时；why为什么；how怎样，如何；that引导宾语从句时，在从句中不充当任何成分，只起连接作用，且无词义。根据句子结构可知，“I believe”后接宾语从句，且从句“sport events can build our character”成分完整，意思表达清晰，不需要额外的词来补充意思或充当成分，所以应该用that来引导这个宾语从句。故选D。 4．—Would you like to see the new movie 731 tomorrow? —Yes, of course. But I am not sure ________ Tony will go. A．why B．what C．that D．if 【答案】D 【详解】句意：——你明天想去看新电影《731》吗？——当然，但我不确定托尼是否会去。 考查宾语从句。why为什么；what什么；that那；if是否。根据句意，空格处需填入表示“是否”的引导词，表达不确定托尼是否会去。故选D。 5．Please let us know ________ you need help.

A．when B．if C．what D．how 【答案】B 【详解】句意：——你想去山里野餐吗？——我想去，但我不确定那天天气是否好。 考查宾语从句的引导词。when什么时候；if是否；what什么；how怎样。根据“I’d like to, but I’m not sure…the weather will be fine on that day”可知，此处是不确定天气“是否”好，需用表示“是否”的连接词引导宾语从句。if 在此处意为“是否”，符合语境。故选B。 7．—What did Peter say to you just now, Kate? —He asked me ________. A．if I have read the book Little Women B．whether will I believe in him C．if I had joined the music club D．whether I will believe in him 【答案】C 【详解】句意：——彼得刚才对你说什么了，凯特？——他问我是否加入了音乐俱乐部。 考查宾语从句的语序和时态。根据“He asked me...”可知，本句为宾语从句，宾语从句需用陈述语序，排除B；主句“He asked”为一般过去时，从句时态也应用过去的某个时态，排除A和D (现在完成时和一般将来时)。故选C。 8．—I’m planning a trip to Harbin this summer vacation.

A．though B．whether C．unless D．until 【答案】B 【详解】句意：——爱丽丝，我想知道你们昨天是否赢了拔河比赛。——是的！我们齐心协力，最终成功了。 考查宾语从句引导词辨析。though尽管；whether是否；unless除非；until直到。根据答语“Yeah! We pulled together and made it in the end.”可知，问句是在询问“是否”赢得了比赛，且wonder后常接whether/if引导的宾语从句表示“想知道是否……”。故选B。 10．I don’t know ________ he will come to my birthday party or not.

A．its newest product will B．that its newest product would C．its newest product would D．that its newest product will 【答案】B 【详解】句意：据称，该研究团队发现植物有助于护肤，并且其最新产品也将很快投入市场。 考查宾语从句和动词的时态。根据“the research team had found that plants could help with skin care, and…soon be in the market.”可知此处是宾语从句，需与第一个从句结构平行，也需用that引导，故排除A、C；又根据“had found”可知，句子时态遵循“主过从必过”的原则，故此时空格处句子时态应用过去将来时，故选B。 14．I don’t doubt ________ he can do the job well, but I doubt ________ he can finish it on time. A．if; that B．that; whether C．that; that D．whether; if 【答案】B 【详解】句意：我不怀疑他能做好这项工作，但我怀疑他是否能按时完成。 考查宾语从句、。if如果，是否；that引导宾语从句，无实义；whether是否。第一空，根据“I don’t doubt”可知，此处是“我不怀疑他能做好这项工作”，表示肯定的意义，应该用that引导宾语从句；第二空，根据“but I doubt”可知，此处是“我怀疑他是否能按时完成”，表示疑问，应该用whether引导宾语从句。故选B。 15．—What do you know about IoT? —I know ________ it stands for Internet of Things. A．if B．that C．how D．whether 【答案】B 【详解】句意：——你对IoT了解多少？——我知道它代表物联网。 考查宾语从句连接词辨析。if是否；that无实义，仅起连接作用；how如何；whether是否。根据答句“I know...it stands for Internet of Things.”可知，从句“it stands for Internet of Things”是一个完整的陈述句，不缺成分，需用that引导宾语从句，起连接作用，无实际含义。故选B。 16．—Do you know a famous saying “A book holds a house of gold”? —Yes, it tells us ________. A．why books are very expensive B．how we can get a lot of money C．that reading can open our minds D．why it is important to buy books 【答案】C 【详解】句意：——你知道“书中自有黄金屋”这句名言吗？——是的，它告诉我们阅读可以开阔我们的思维。 考查宾语从句。why books are very expensive为什么书很贵；how we can get a lot of money我们如何能赚很多钱；that reading can open our minds阅读可以开阔我们的思维；why it is important to buy books为什么买书很重要。根据谚语“A book holds a house of gold”可知，“书中自有黄金屋”的寓意，它强调的是读书的价值和益处，而非字面上的金钱或买书行为。选项C最符合该谚语传达的“读书使人明智、开阔眼界”的内涵。故选C。 17．She was not sure ________ she could do it well all by herself.

A．that you can take the lead B．whether you can learn it well C．who can you ask for help D．why you began to learn English 【答案】B 【详解】句意：语言学习本身并不难。你花多少时间在上面决定了你是否能学好它。 考查宾语从句。that you can take the lead 你可以领先；whether you can learn it well 你是否能学好它；who can you ask for help 你可以向谁求助；why you began to learn English 你为什么开始学英语。分析句子可知，空处在句中作宾语，所以是宾语从句，应用“陈述句语序”，排除C；根据“how much time you spend on it decides…”（你花多少时间在上面决定了……）可知，这里需要一个能体现学习结果的宾语从句，且“whether”最符合“决定学习效果”的语境，故选B。 19．—________ did you say to our English teacher? —I asked her ________ I had passed the exam or not. A．How; if B．What; whether C．What; if D．How; whether 【答案】B 【详解】句意：——你对我们英语老师说了什么？——我问她我是否通过了考试。 考查疑问词和宾语从句引导词辨析。How怎样；What什么；if是否；whether是否。根据“... did you say to our English teacher?”可知，缺少say的宾语，用what；根据“... I had passed the exam or not.”可知，此处是whether...or not“是否”的固定搭配。故选B。 20．—I want to know if it ________ tomorrow. —Me, too. If it ________, we will have to stay at home. A．will rain; rains B．rains; rains C．will rain; will rain D．rains; will rain 【答案】A 【详解】句意：——我想知道明天是否会下雨。——我也是。如果明天下雨，我们将不得不待在家里。 考查if从句的时态用法。will rain将会下雨，一般将来时；rains下雨，一般现在时。在第一个句子中，if引导宾语从句，根据时间状语“tomorrow”可知，从句需用一般将来时；在第二个句子中，if引导条件状语从句，表示将来条件时，从句需用一般现在时代替将来时，主句用一般将来时。故选A。 21．He isn’t sure if it ________ next Sunday. If it ________, he won’t go camping. A．will rain; rainy B．rains; rains C．will rain; rains D．rain, rain 【答案】C 【详解】句意：他不确定下周日是否会下雨。如果下雨，他就不去露营了。 考查动词时态和条件状语从句。第一个空，根据“next Sunday”可知，此处是if引导的宾语从句，从句的动作还没有发生，所以用一般将来时，其结构为“will+动词原形”，即will rain；第二个空，根据语境可知，此处是if引导的条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时表将来，从句主语it是第三人称单数，所以谓语动词用三单形式rains。综上，第一个空填will rain，第二个空填rains。故选C。 22．—Can you tell me if it ________ tomorrow? —I’m not sure, I will go swimming if it ________ tomorrow. A．will rain; doesn’t rain B．will rain; won’t C．rains; will rain D．rains; won’t 【答案】A 【详解】句意：——你能告诉我明天是否会下雨吗？——我不确定，如果明天不下雨我就去游泳。 考查动词时态。第一个空，“if”引导的是宾语从句，意思是“是否”，根据“tomorrow”可知，此句描述的是将来的事情，所以要用一般将来时“will rain”；第二个空，“if”引导的是条件状语从句，意思是“如果”，在条件状语从句中，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时，所以这里应该用一般现在时的否定形式“doesn’t rain”。故选A。 23．I don’t know if she ________ to my birthday party tomorrow. If she ________, I’ll be happy. A．will come; will come B．comes; comes C．will come; comes D．comes; will come 【答案】C 【详解】句意：我不知道她明天是否会来参加我的生日派对。如果她来，我会很高兴。 考查条件句和宾语从句的时态用法。will come将会来，一般将来时；comes来，一般现在时的第三人称单数形式。根据“I don’t know if she...tomorrow”可知此处第一个空if 引导宾语从句，表示“是否”，从句中有将来时间状语tomorrow，需用一般将来时will come；根据“If she...I’ll be happy”可知第二个空，if引导条件状语从句，表示“如果”，需用一般现在时comes表示将来。故选C。 24．—Jenny, do you know if your mother ________ back tomorrow? —Sorry, I don’t know. If she ________ home, I’ll tell her to call you. A．comes; gets B．comes; gets to C．will come; gets D．will come; gets to 【答案】C 【详解】句意：——珍妮，你知道你妈妈明天是否会回来吗？——对不起，我不知道。如果她到家，我会让她给你打电话的。 考查if引导的宾语从句和条件状语从句的时态。第一空，根据语境可知，此处是询问是否明天回来，所以用一般将来时will come；第二空，根据“If she...home, I’ll tell her to call you.”可知，这是一个条件状语从句，遵循“主将从现”原则，即主句用一般将来时，从句用一般现在时表将来，且home为地点副词，其前不用介词，所以第二空应填gets。故选C。 25．I doubt ________ the newly found cave is safe for tourists to visit without professional guidance. A．that B．if C．what D．which 【答案】B 【详解】句意：我怀疑这个新发现的洞穴在没有专业指导的情况下对游客来说是否安全。 考查宾语从句引导词辨析。that无实义，仅起连接作用；if是否；what什么；which哪一个。主句动词为“doubt”，在肯定句中表示“怀疑、不确定”时，其后宾语从句常用“if”或“whether”引导，表示“是否”；根据句意，此处表达“不确定是否安全”，应选用“if”。故选B。 26．It depends on ______ we have enough time, not on ______ the weather is good. A．whether; whether B．whether; if C．if; whether D．if; if 【答案】A 【详解】句意：这取决于我们是否有足够的时间，而不取决于天气是否好。 考查连词辨析。whether是否；if是否。在介词后引导宾语从句时，只能用whether，不能用if。第一个空位于介词on后，只能用whether；第二个空也在介词on后，同样需用whether。故选A。 27．Hope ________ tomorrow morning. A．her to come to my home B．her come to my C．she come to my home D．she can come to my home 【答案】D 【详解】句意：希望她明天早上能来我家。 考查hope和宾语从句的用法。根据“Hope…tomorrow morning.”可知，hope“希望”，动词，不能构成短语“hope sb. to do sth.”，排除A选项和B选项；hope后可以接省略that的宾语从句，she作主语，谓语动词应用第三人称单数形式，排除C选项。故选D。 28．The saying “One cannot put back the clock” tells us ________. A．where should we put the clock B．what people can’t do with the clock C．that it is necessary to make good use of time D．why can’t we make the clock walk more slowly 【答案】C 【详解】句意：“时光不能倒流”这句谚语告诉我们，必须充分利用时间。 考查宾语从句。分析句子，空格处为宾语从句，应用陈述句语序，排除选项A和D；“One cannot put back the clock”意为“时光不能倒流”，是告诉我们必须充分利用时间。故选C。 29．I often make you ______ because I hope you ______ happy. A．laugh, will be B．laugh, to be C．to laugh, will be D．laughing, to be 【答案】A 【详解】句意：我经常逗你笑，因为我希望你会快乐。 考查动词用法。make sb. do sth.意为“使某人做某事”，固定用法，故第一空用原形，排除C/D选项，hope的用法是hope to do sth“希望做某事”，或者hope+宾语从句，此处是hope接从句的用法，故选A。 30．I’m sure ________ she can do it well, but I doubt ________ she is willing to do it. A．that; that B．if; if C．that; if D．if; that 【答案】C 【详解】句意：我确信她能把这件事做好，但我怀疑她是否愿意做这件事。 考查宾语从句引导词。第一个从句不缺成分，意义完整，后接that引导的宾语从句；第二个空“doubt”表示不确定、有疑问时，后接宾语从句常用“if”或“whether”引导，表示怀疑某事是否会发生或是否属实等情况。故选C。 31．Last night my mother said ________ she would take me to the history museum.

A．if B．whether C．that D．how 【答案】C 【详解】句意：我的爸爸总是说我妈妈是世界上最好的厨师。    考查宾语从句引导词辨析。if是否；whether是否；that无实际意义（引导陈述句宾语从句）；how如何。根据“my mom is the best cook in the world”可知，从句是结构完整的陈述句，不缺成分和语义，因此用that引导宾语从句。故选C。 34．—Do you know ________ red stands for good luck in China? —Sure.

A．whether: that B．that: if C．if: whether D．that: that 【答案】B 【详解】句意：——我从不怀疑她能做好这件事。——我也不怀疑。我只是怀疑她是否愿意做这件事。 考查宾语从句引导词。在宾语从句中，“doubt”用于否定句时，后面接“that”引导的从句；用于肯定句时，后面接“if”或“whether”引导的从句。第一空，“never doubt”表否定，用“that”；第二空，“doubt”表肯定，用“if”。故选B。 39．I found ________ difficult to get used to life in foreign countries. A．it is B．it was C．that D．that was 【答案】B 【详解】句意：我发现很难适应国外的生活。 考查宾语从句。原句需使用“find it +形容词+to do”句型，其中it作形式宾语，但选项中没有单独的it。B项it was可构成宾语从句“I found (that) it was difficult to get used to...”，时态一致（found与was均为过去式），意思通顺。A项it is时态不一致；C项that后接形容词，结构不完整；D项that was易引发歧义。故选B。 40．The boy asked his father ________. A．which room he would live in the hotel B．how life would be like in the year 2100 C．how he called the man under the tree D．if Shakespeare was a great writer 【答案】D 【详解】句意：这个男孩问他的父亲莎士比亚是不是一个伟大的作家。 考查宾语从句。选项A中动词live后要借助介词in才能和which room搭配，句中虽然有一个介词in，但它是和后面的hotel搭配的，因此这句话存在语法错误；选项B中how与would be like搭配错误，应把how改成what；选项C中从句的引导词充当宾语补足语，应把how改成what；选项D中引导词、时态以及句子结构都正确。故选D。 二、完成句子 41．will, she, food problem, ways, the, believes, solve, people, find, to (连词成句) 【答案】She believes people will find ways to solve the food problem. 【详解】根据所给单词和标点符号可知，本句是一个宾语从句。She“她”，句首首字母大写，主句的主语； believes“相信”，主句的谓语；people“人们”，从句的主语；will find“将会找到”，从句的谓语；ways“方法”，从句的宾语；to solve the food problem“解决粮食问题”，后置定语。故填She believes people will find ways to solve the food problem.“她相信人们将会找到解决粮食问题的办法”。 42．Our body relaxes when we laugh, so laugh a lot. A survey shows the finding. (改为宾语从句) A survey shows our body when we laugh, so laugh a lot. 【答案】 that relaxes 【详解】句意：一项调查显示，当我们笑的时候身体会放松，所以要多笑。原句需要合并为含宾语从句的复合句，动词shows后接宾语从句时，通常用that引导，that在从句中无实际意义，可省略但此处需填空；宾语从句需遵循“主句为一般现在时，从句时态灵活”的时态规则，主句“A survey shows”为一般现在时，从句描述客观事实，也用一般现在时；主语“our body”为单数，因此动词relax需用第三人称单数形式relaxes。故填that；relaxes。 43．That sign means: Don’t smoke inside the library! (保持句意基本不变) That sign means isn’t inside the library. 【答案】 that smoking allowed 【详解】句意：那个标识的意思是：不要在图书馆内吸烟！此句可表述为“那个标识的意思是在图书馆吸烟是不被允许的”，means后面跟that引导的宾语从句，smoking作主语，谓语动词用单数isn’t；“smoking”与“allow”是被动关系，其结构是“be + done”，allow的过去分词是allowed，应用被动语态。故填that；smoking；allowed。 44．I hope to be back soon. (改为同义句) I hope back soon. 【答案】 that I will be 【详解】句意：我希望很快回来。hope to do sth.“希望做某事” 的同义结构为“hope that + 从句”，从句主语是I，时态为一般将来时，结构为will+动词原形，be back soon“很快回来”。故填that；I；will；be。 45．原句：This experience taught me that hard work can lead to success. 仿写：This experience taught me that . 【答案】perseverance can help us achieve our goals 【详解】根据仿写结构可知，此处需要填入一个由连词“that”引导的宾语从句，表达“这件事告诉我……(的道理)”。仿写示例“perseverance can help us achieve our goals”意为“坚持能帮助我们达成目标”，是完整的陈述句，在从句中作动词“taught”的直接宾语。故填perseverance can help us achieve our goals。 46．老师经常告诉我们，为了自己的安全，我们应该遵守交通规则。 Our teacher often tells us . 【答案】we should follow traffic rules for our own safety 【详解】根据中英文对照可知，此处缺少“我们应该遵守交通规则为了自己的安全”。we should follow traffic rules for our own safety“我们应该为了自己的安全遵守交通规则”，是一个完整的宾语从句；主句动词“tells”后接双宾语“us”和从句，从句部分陈述一个事实。故填we should follow traffic rules for our own safety。 47．Does he go to Central Park? Could you tell me? (改为宾语从句) Could you tell me he to Central Park? 【答案】 if/whether goes 【详解】句意：他去中央公园吗？你能告诉我吗？原句为一般疑问句，改为宾语从句时，需要使用if/whether引导，表示“是否”；原句时态为一般现在时，宾语从句主语为he，动词应使用第三人称单数形式goes。故填if/whether；goes。 48．I don’t know whether he will come or not. (改为同义句) I don’t know he will come. 【答案】if 【详解】句意：我不知道他是否会来。原句中的“whether…or not”可以替换为“if”来表达相同含义，两者都表示“是否”的意思。故填if。 49．我不知道史密斯先生是在家还是在他的办公室。 I don’t know Mr. Smith is at home at his office. 【答案】 whether or 【详解】根据中英文对照可知，空格处表示“是……还是……”的含义；“I don’t know”后接宾语从句，此处需用“whether...or...”表示“是否……还是……”，来引导宾语从句，连接“在家”和“在办公室”这两个选择项。故填whether；or。 50．“Do you like reading novels?” Tom asked me. (改为宾语从句) Tom asked me I reading novels. 【答案】 if/whether liked 【详解】句意：“你喜欢读小说吗？”汤姆问我。直接引语变为宾语从句时，若原句为一般疑问句，要用if或whether引导宾语从句，同时从句要用陈述语序，且主句为一般过去时，从句也要用相应的过去时态，like的过去式为liked。故填if/whether；liked。 51．I want to know. Will she take part in the summer camp for personal growth? (合并为宾语从句) I want to know she take part in the summer camp for personal growth. 【答案】 if/whether will 【详解】句意：我想知道她是否会参加那个用于个人成长的夏令营。原句是一般将来时的一般疑问句，合并为宾语从句时需用引导词if/whether表“是否”，且从句要改为陈述语序，助动词will放在主语she之后，故填if/whether；will。 52．桑迪问我是否喜欢这个生日礼物。 Sandy asked me I liked the birthday present . 【答案】 whether or not 【详解】根据中英文对照可知，此处缺少“是否”。宾语从句引导词应为whether，whether...or not是一个固定搭配，强调“是或否”的选择。故填whether；or；not。 53．我很惊讶这些房子建于明朝。 I these houses date from the Ming Dynasty. 【答案】 am surprised that 【详解】be surprised that“惊讶于……”，that引导宾语从句，根据“date”可知，主句可采用一般现在时，主语为I，be动词用am。故填am；surprised；that。 54．I   help   school life   our   hope   suggestions   improve   my 【答案】I hope my suggestions help improve our school life. 【详解】根据所给单词可知，此句是肯定句。I hope是主谓结构，是宾语从句的主句；my suggestions是宾语从句的主语；help作谓语；improve our school life是不带to的不定式短语作宾语。故填I hope my suggestions help improve our school life.“我希望我的建议能够有助于改善我们的校园生活。” 55．这位年轻选手已经证明他能在重要比赛中表现出色。 The young player he can play well in important games. 【答案】 has proved that 【详解】根据中英文对照可知，此处缺少“已经证明”。句子表达“已经证明”，表示动作从过去持续到现在，需用现在完成时，结构为“have/has+过去分词”。主语“The young player”是第三人称单数，因此用助动词has；“证明”英文表达为“prove”，过去分词是proved；prove后接宾语从句，从句结构、语意完整，故用that引导从句。故填has；proved；that。 56．我什么也看不见，也不知道周围还有没有其他人。 I see anything , and I didn’t know anyone else was around me. 【答案】 couldn’t at all if/whether 【详解】根据“didn’t know”可知，时态为一般过去时，“什么也看不见”对应否定表达“couldn’t see anything at all”，“couldn’t”表示“不能”，“not...at all”是固定短语，表示“根本不、一点也不”；“不知道周围有没有其他人” 中，“有没有”在宾语从句中用“if/whether”引导（表 “是否”）。故填couldn’t；at；all；if/whether。 57．I want to know. Will they launch the expedition to the Arctic next spring? (合并为宾语从句) I want to know they the expedition to the Arctic next spring. 【答案】 if/whether will launch 【详解】句意：我想知道。他们明年春天将会发起前往北极的探险吗？此处合并为宾语从句，“Will they launch the expedition to the Arctic next spring?”是一般疑问句，故此处宾语从句的连接词用if/whether；主句是一般现在时，原疑问句中的一般将来时will launch在宾语从句中语序应改为陈述句语序 (主语 + 谓语)，时态不变。故填if/whether；will；launch。 58．他们想知道这个博物馆周末是否开放。 They   the museum is open on weekends. 【答案】 wonder if/whether 【详解】根据句意可知，此处表示“想知道”且后面接宾语从句，用动词“wonder”；同时需要一个词来引导宾语从句表示“是否”，用“if”或“whether”。故填wonder；if/whether。 59．当哈利看到他帮助过的人脸上洋溢着笑容时，他意识到自己的努力是值得的。 Harry his work when he saw the smiles on the faces of the people he helped. 【答案】 realized that was worth the effort 【详解】根据中英文对照可知，此处缺少“意识到……是值得的”。realize that“意识到……”，后接宾语从句，描述过去事实，需用一般过去时“realized”。be worth the effort“努力是值得的”，系表结构，在从句中作谓语。故填realized；that；was；worth；the；effort。 60．想象一下你刚刚赢得一百万英镑。 you have just won a million pounds. 【答案】 Imagine that 【详解】根据所给汉语意思可知，空缺处应该填的是“想象一下”，动词imagine意为“想象”，位于句首首字母大写；后接宾语从句，用that引导，故填Imagine；that。 16 立足新教材，自学有章法，练习有重点！ 17 立足新教材，自学有章法，练习有重点！ 学科网（北京）股份有限公司 $ 2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ 2025-2026学年一线教师制作新教材英语核心题型讲通练透系列资料，名师甄选！ 学校:___________姓名：___________班级：___________考号：___________ Unit 5 Looking into nature 单元Grammar：that、if、whether引导的宾语从句易错题精练60题   语   法   精   讲 一、基本概念 1.宾语从句定义：在句中作及物动词 / 介词 / 形容词的宾语，由连接词引导的名词性从句 2.三类引导词共性：连接主句和从句，无实在意义（if/whether 表 “是否” 除外），不充当从句成分 二、that 引导的宾语从句 1. 适用情况 主句谓语为陈述类及物动词：say, tell, think, believe, know, hope, find, feel 等 从句为陈述句（表达事实、观点、陈述） 2. 核心用法 that 无词义，不充当从句成分，可省略（主句谓语后直接接从句时） 特例：并列宾语从句中，第二个及以后的 that不可省略（如 He said (that) he was late and that he was sorry.） 3. 例句 I think (that) English is easy. She told me (that) she would go to Beijing. 三、if/whether 引导的宾语从句 1. 适用情况 主句谓语为疑问类及物动词：ask, wonder, want to know, check, find out 等 从句为一般疑问句（表达疑问、不确定） 2. 核心共性 均表 “是否”，无其他词义，不充当从句成分 从句需用陈述语序（主谓不倒装，无助动词提前） 3. 例句（通用） He asks if/whether I like reading.
