A．how to do it B．what to do it C．how to do D．what do it 【答案】A 【详解】句意：——你觉得这个数学题怎么样？——它太难了。我真的不知道如何解决它。 考查疑问词+不定式的用法。“疑问词+不定式”作know的宾语时，需要注意疑问词的功能：how是方式副词，需与及物动词do的宾语搭配，即“how to do it（如何做这道题）”；what是代词，可直接作do的宾语，结构应为“what to do”，无需额外加it。故选A。 2．Let me ________ you how ________ this camera. A．show; to use B．to show; use C．showing; using D．show; using 【答案】A 【详解】句意：让我给你展示如何使用这个相机。 考查非谓语动词。show展示，动词原形；to show动词不定式；showing动名词/现在分词；to use动词不定式；use使用，动词原形；using动名词/现在分词。根据“Let me”可知，“Let sb. do sth.”是固定结构，意为“让某人做某事”，所以第一空用动词原形show；第二空“how to do sth.”是“疑问词+不定式”结构，意为“如何做某事”，所以用to use。故选A。 3．A mother tiger stays with her babies and takes care of them. She finds food for them and also teaches them ________ food. A．what to look for B．how to look for C．what to find out D．how to find out 【答案】B 【详解】句意：母老虎会和幼崽待在一起并照顾它们。它会为幼崽觅食，还会教它们如何寻找食物。 考查疑问词+不定式的用法及动词短语辨析。what to look for寻找什么；how to look for如何寻找；what to find out查明什么；how to find out如何查明。look for强调动作，而find out强调经过调查、探究后的结果。根据“She finds food for them and also teaches…”语境可知，此处指母老虎教幼崽寻找食物的方式，强调过程，用how to look for。故选B。 4．Can you teach me how ______ steamed eggs? A．make B．making C．to make D．made 【答案】C 【详解】句意：你能教我怎么蒸蛋吗？ 考查动词不定式用法。在“teach sb. how to do sth.”结构中，应使用动词不定式“to+动词原形”表示“如何做某事”。故选C。 5．—It’s important for us ________ know ________ all the subjects. —Yeah, group work is my favorite. A．to; how to study B．of; when to study C．on; which to study D．to; what to study 【答案】A 【详解】句意：对我们来说，知道如何学习所有科目是重要的。 考查it作形式主语和疑问词+不定式用法。to朝向，与动词原形构成不定式，how to study如何学习；of属于……的，后加动名词，when to study什么时候学习；on在……上面，后加动名词，which to study学哪个；to朝向，与动词原形构成不定式，what to study学什么。根据“It’s important for us...know...all the subjects.”可知，It’s+adj.+for sb.+to do sth.“对于某人来说做某事是……的”，此处用动词不定式，排除BC选项，all the subjects已包含要学习的内容，与what to study矛盾。故选A。 6．There is no difference between the two sweaters, so I really don’t know ________. A．which one to choose B．which choose one C．which to choose one D．to choose which one 【答案】A 【详解】句意：这两件毛衣没有区别，所以我真的不知道选哪一个。 考查疑问词+不定式的结构。根据“There is no difference between the two sweaters, so I really don’t know...”可知，此处指不知道选哪一个，属于“疑问词+不定式”的固定语法结构，排除B和D；C项“which to choose one”语序错误，which to choose后不应直接加one，one放在which后，排除C。故选A。 7．—I don’t know ________ to use this machine. —Don’t worry. Let me show you. A．what B．how C．which D．where 【答案】B 【详解】句意：——我不知道如何使用这台机器。——别担心。让我展示给你看。 考查疑问词辨析。what什么；how如何；which哪一个；where哪里。根据答语“Let me show you.”可知，此处表达不知道使用这台机器的方式，how符合。故选B。 8．Different club activities at school can offer students fun. Among the clubs, many students like to join the nature club because they can learn _______ plants in the right place. A．what to plant B．which to plant C．how to plant D．when to plant 【答案】C 【详解】句意：不同的学校俱乐部活动可以给学生带来乐趣。在众多俱乐部中，许多学生喜欢加入自然俱乐部，因为他们可以学习如何在正确的地方种植植物。 考查“疑问词+不定式”的用法及上下文匹配。句子结构为“learn+疑问词+to plant+plants in the right place”，其中“plants”是“plant”的宾语，因此选项需语法正确且语义通顺。选项A“what to plant”和B“which to plant”本身已隐含宾语（“what”或“which”作宾语），不能再接“plants”，会造成语法错误；选项D“when to plant”强调时间，不符合语境；选项C“how to plant”表示方式方法，可带宾语“plants”，且“如何种植”与“在正确的地方”在语境中自然搭配，指学习种植的方法和位置选择，符合自然俱乐部的活动特点。故选C。 9．They were wondering where ________ the office party and I suggested ________ to the Chinese restaurant near the station. A．to hold; going B．holds; to go C．to hold; to go D．holding; going 【答案】A 【详解】句意：他们正在琢磨在哪里举行办公室聚会，我建议去车站附近的中国餐馆。 考查非谓语动词。“where+动词不定式”结构作“wonder”的宾语，表示“在哪里做某事”；“suggest”后接动名词作宾语，表示“建议做某事”。故选A。 10．Do you have anything to ________? If something ________ you, do you know who ________? A．worry; worries; to go B．worry about; worries; to go C．worry; worries about; can go to D．worry about; worries; to go to 【答案】D 【详解】句意：你有什么担心的事吗？如果有事困扰你，你知道去找谁吗？ 考查动词短语、动词时态以及非谓语动词。worry使……担心；worry about担心，及物动词短语。第一空，表示“担心某事”，应用worry about，排除A和C；第二空，主语是something，为第三人称单数，谓语动词用三单形式，即worries；第三空，此处表示“去找谁”，应用动词不定式，且go为不及物动词，后接宾语需加介词to，即to go to。故选D。 11．During our trip to the farm, the farmer showed us ________ to pick fresh tea leaves in the morning and we learned well. A．when B．how C．what D．which 【答案】B 【详解】句意：在去农场的旅行中，早上农民向我们展示了如何采摘新鲜的茶叶，我们学得很好。 考查疑问词辨析。when什么时候；how如何；what什么；which哪一个。根据“the farmer showed us...to pick fresh tea leaves”可知，此处指农民向我们展示如何采摘新鲜茶叶，用how表示“如何”。故选B。 12．When I feel down, my best friend always knows how ______ me up. A．cheer B．cheering C．to cheer D．cheers 【答案】C 【详解】句意：当我情绪低落时，我最好的朋友总是知道如何让我振作起来。 考查“疑问词+不定式”的结构。根据“my best friend always knows how...me up”可知，“how to do sth.”是“疑问词+不定式”的常见形式，表示“如何做某事”，此处表示如何让“我”振作起来，符合语境。故选C。 13．—Ms. Sha, could you tell me ________? —I think you need a heart-to-heart talk. A．what can I solve my problems with my friends B．how can I solve my problems with my friends C．what to solve my problems with my friends D．how to solve my problems with my friends 【答案】D 【详解】句意：——沙老师，您能告诉我如何解决和朋友们之间的问题吗？——我认为你需要进行一次坦诚的交谈。 考查宾语从句及“疑问词+不定式”结构。根据“could you tell me...”可知，后面可以接宾语从句，此时宾语从句要用陈述语序，A、B选项均为疑问语序，可排除；也可以接“疑问词+不定式”结构作宾语，结合答语“I think you need a heart-to-heart talk.”可知，问句是询问解决问题的方式，所以用疑问词how，what表示“什么”，不符合语境，可排除C选项，D选项“how to solve my problems with my friends”表示“如何解决我和朋友们之间的问题”，符合题意。故选D。 14．Thomas Adams didn’t know ________ to do to help his chewing gum company ________ the economic crisis (危机). A．how; survive B．how; survive in C．what; survive D．what; survive in 【答案】C 【详解】句意：托马斯・亚当斯不知道做什么来帮助他的口香糖公司度过经济危机。 考查疑问词和动词辨析。how如何；survive幸存，度过；survive in生存；what什么。根据“to help his chewing gum company”可知，第一空表示做什么来帮助公司，需用what to do表示；根据“economic crisis (危机).”可知，第二空表示度过危机。故选C。 15．We students should learn ________ ourselves at school.

A．of; what to B．for; how to C．of; how to D．for; what to 【答案】B 【详解】句意：——对他来说，独自修理自行车是不可能的。——他应该学习如何寻求帮助。 考查介词辨析及不定式结构。“It’s+adj.+for sb. to do sth.”表示“对某人来说做某事是……的”；此处impossible是描述事物的形容词，介词用for；how to get help表示“如何寻求帮助”，符合题意；what to get help表述错误。故选B。 17．— Did you tell your mother ________ you? — Yes, at the school gate. A．when meeting B．when to meet C．where meeting D．where to meet 【答案】D 【详解】句意：——你告诉你妈妈在哪里见你了吗？——是的，在学校门口。 考查非谓语动词和疑问词辨析。when meeting当见面时；when to meet什么时候见面；where meeting在哪里见面；where to meet在哪里见面。根据答语“at the school gate”可知，此处是询问见面的地点，所以用where，且空格处是“疑问词+动词不定式”作宾语。故选D。 18．I really don’t know what _______ next.
