It’s too hard. —You can ask Mr Wang for help. A．which to do B．when to do C．what to deal D．how to deal 【答案】D 【详解】句意：——我不知道如何处理他的问题。它太难了。——你可以向王老师寻求帮助。 which to do做哪个；when to do何时做；what to deal错误搭配；how to deal如何应对/处理。deal with意为“处理”，常与how连用，构成how to deal with结构；do with常与what连用，构成what to do with结构。根据空后“with his problem”及语境可知，此处表示处理问题的方法，应用how to deal with。 2．I don’t know ______ this old bike. A．how to do with B．what to do with C．what to deal D．how to deal 【答案】B 【详解】句意：我不知道如何处理这辆旧自行车。 “do with”和“deal with”都表示“处理”，但“do with”常与“what”连用，而“deal”是不及物动词，与“how”连用时需要加介词“with”。因此，正确的表达应该是“what to do with”或“how to deal with”。选项A、C、D表达错误，应填what to do with。 3．—Maria, can you give me some advice?

A．what B．how C．when D．where 【答案】B 【详解】句意：——你能告诉我如何加入学校读书俱乐部吗？——你可以先在学校网站上填写表格。 考查疑问词辨析。what什么；how如何；when何时；where何处。根据答句“You can fill in the form on the school website first.”（你可以先在学校网站上填写表格。）可知，问句询问的是加入读书俱乐部的“方式”，因此用how表示“如何”。故选B。 5．—I don’t know ________ next. —Let’s ask our teacher for help. A．how should I do it B．what should I do C．how to do D．what to do 【答案】D 【详解】句意：——我不知道接下来做什么。——让我们向老师寻求帮助吧。 考查宾语从句的语序和“疑问词+不定式”结构。know后接宾语时，宾语从句需用陈述语序，选项A和B为疑问语序，故排除；选项C“how to do”中do为及物动词，缺少宾语，不完整；选项D“what to do”结构完整，what作do的宾语。故选D。 6．That girl is ________ young to know ________. A．so; what to do B．too; what to do C．so; how to do D．too; how to do 【答案】B 【详解】句意：那个女孩太小了，不知道该做什么。 考查固定搭配和疑问词用法。so如此；too太。too…to…表示“太……而不能……”，是固定搭配；what to do表示“该做什么”，其中what作do的宾语，是正确表达；how to do表示“该怎么做”，此处do是及物动词，缺少宾语，结构不完整。故选B。 7．Everybody can learn ________ well.

I have no idea ________.

A．where am I going B．where should I go C．what to prepare D．where to go 【答案】D 【详解】句意：——我不知道即将到来的假期去哪里。——去三亚怎么样？ 考查疑问词+动词不定式结构。分析句子结构可知，空处作know的宾语；A项和B项语序错误，宾语从句应为陈述语序；根据答语“How about going to Sanya?”可知，此处建议的是地点，D项符合。故选D。 12．—I don’t know________ this word. —You can look it up in the dictionary. A．what to spell B．how to spell C．what should I spell D．how should I spell 【答案】B 【详解】句意：——我不知道这个单词怎么拼写。——你可以在字典里查一下。 考查宾语从句。what to spell拼写什么；how to spell如何拼写；what should I spell表述错误；how should I spell表述错误。what是spell的宾语 ，原句已经有this word作spell的宾语， A选项语义重复；“how to spell是“疑问词+不定式”结构，表示“如何拼写” ，符合语境。what should I spell和how should I spell均是特殊疑问句语序，宾语从句种需用陈述句语序。故选B。 13．Self-driving buses are smart.
