A.to buy which B.to buy what C.which to buy D.what to buy
【答案】C

考查“疑问词+不定式”。which哪一个;what什么。此处是“疑问词+不定式”作宾语,根据“There are so many types of smart phones in this shop.”可知,种类太多,所以不知道买哪个,有选择性含义,用which。故选C。

—Let’s ask our teacher for help.
A.what to do B.what should I do C.how to do D.how should I do it
【答案】A

know后接宾语,A项“疑问词 + 不定式”结构正确,what作do的宾语;B项和D项是宾语从句,但使用了疑问语序should I,应改为陈述语序I should;C项do是及物动词,后缺宾语,how是副词不能作宾语,应为how to do it。
10.Could you tell me how ________ the library?

14.The group members are discussing when they will start doing the experiment. (改为简单句)
The group members are discussing ________ ________ start doing the experiment.

15.Please decide which course you will take immediately. (改为简单句)
Please decide which course ________ ________ immediately.
【答案】to take
【详解】句意:请立即决定选哪门课。根据“Please decide which course you will take immediately.”可知,此处应将宾语从句“which course you will take”改为“疑问词+动词不定式”结构作宾语,因此用which course to take。故填to;take。

A.when to do B.where to do C.what to do it D.how to do it

考查“疑问词+不定式”结构。when to do何时做;where to do何地做;what to do it表述错误;how to do it 如何做。根据前句“by ourselves”可知,此处强调“没有人告知做事的方式”,“how to do it”符合“疑问词+不定式”的正确结构,故选D。
2.—Wow, Julie, it’s so cool to take some photos with your mobile phone.
—Just with a software called MTxiuxiu. Let me show you ________.
A.what to use B.how to use it C.which to use D.where to use it

A.changing B.changed C.to change D.will change
【答案】C
【详解】句意:阅读盒子上的说明,你就会知道如何更换电池。

A.how to deal with; listening to B.what to deal with; taking
C.what to do with; listening D.how to do with; taking
【答案】A
【详解】句意:青年工作者总是知道如何处理青少年问题,他们的建议非常值得倾听。
deal with常与how连用,do with常与what连用,因此排除 B、D 选项;be worth doing意为“值得做某事”,listen是不及物动词,接宾语advice时需加介词to,故此处应用listening to。
6.—I don’t know ________ with his problem. 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。

8.Could you tell me where ________ the bank?
A.to find B.can I find C.how to find D.find
【答案】A
【详解】句意:你能告诉我在哪里可以找到银行吗?
考查宾语从句。分析题干可知,此处考查宾语从句。从句应用陈述句语序,所以此处应是“where I can find”,或者可以简化为“特殊疑问词+动词不定式”结构,即“where to find”。故选A。
9.Before we have a picnic in the mountains, we have to learn ______ to do to protect ourselves first.
A.when B.how C.what D.who
【答案】C
【详解】句意:在我们在山上野餐之前,我们必须首先学习如何保护自己。
考查疑问词。when什么时候;how如何;what什么;who谁。根据“we have to learn...to do”可知,是指学习做什么,此处应用疑问代词what作do的宾语,故选C。
10.There are so many kinds of T-shirts. We can’t decide_____.
A.to choose B.what to buy
C.which one to choose D.to buy
【答案】C
【详解】句意:有很多种T恤衫。我们无法决定选哪一个。
考查疑问词加动词不定式。根据句子结构,动词decide后接宾语,“特殊疑问词+ to do”可作宾语,且前面一句已指明是在T恤衫里挑选一件,不存在不能决定买什么的意思,故C选项最为符合句意,故应选C。
【点睛】常和“疑问词+动词不定式”结构连用的动词及短语有:know、learn、see、hear、ask、tell、advise、decide、explain、find out。例如:
I don’t know what to do. 我不知道该做什么。
He could not tell whom to trust. 他不知道该相信谁。
11.Can you tell me where I can park my car around here?(改为简单句)

【答案】where to
【详解】句意:你能告诉我在这附近在哪儿停车吗?原句是宾语从句:where I can park my car around here,“疑问词 + 主语 + can + 动词原形”的宾语从句,可直接简化为: 疑问词 + to + 动词原形,where I can park → where to park,故填where;to。
12.The tourist wondered where he could exchange the money easily. (改成简单句)
The tourist wondered ________ ________ exchange the money easily.
【答案】where to
【详解】句意:这名游客想知道在哪里可以方便地兑换钱。根据题目要求,将复合句改为简单句,原句结构:“where he could exchange the money easily”是一个宾语从句,作动词“wondered”的宾语,当宾语从句的引导词是疑问词(where, what, how, when 等),且从句的主语与主句主语一致时,可以将从句改为“疑问词+动词不定式(to do)”,即“where to exchange...”。故填where;to。
13.With two invitations in hand, she wondered which one she should accept. (改为简单句)
With two invitations in hand, she wondered which one _________ _________.
【答案】to accept
【详解】句意:手里拿着两份邀请函,她不知道该接受哪一个。原句为含有宾语从句的复合句,当主句主语与从句主语一致时,可改为“疑问词 + 动词不定式”的简单句结构,所以此处应填动词不定式to accept。
14.This program aims to teach students how they can stay safe online. (改为简单句)
This program aims to teach students ________ ________ stay safe online.
【答案】how to
【详解】句意:这个项目旨在教学生如何在网上保障安全。题目要求改为简单句,原句中的宾语从句how they can stay safe online可以替换为“疑问词 + 不定式”结构,即how to stay safe online,该结构可以直接作动词teach的宾语补足语。故填how;to。
15.She’s considering whether she will visit the robotics exhibition. (改为简单句)
She’s considering ________ ________ visit the robotics exhibition.
【答案】whether to
【详解】句意:她正在考虑是否去参观机器人展览。原句包含一个由“whether”引导的宾语从句。改为简单句,可将宾语从句转换为动词不定式短语“whether to do sth.”,作为“consider”的宾语。故填whether;to。

【详解】1.句意:他们经常感到压力大,不知道如何处理这些问题。

2.句意:一项最近的调查显示,大多数学生每天有太多作业。
“shows”后接宾语从句,从句陈述事实,应用that引导,that“(引导宾语从句,无意义)”符合语境,if“是否”、whether“是否”和what“什么”不符。

“we should learn to plan our time carefully”是陈述的内容,应用that“(引导宾语从句,无意义)”引导,what“什么”、if“是否”和whether“是否”不符。

【导语】本文围绕人类当前的太空探索活动展开,介绍了相关探索举措、航天员的工作内容与任务、已取得的探索进展,同时表明人类对太空探索抱有极高期待,将持续推进相关研究,以期未来实现造访其他行星的目标。
【详解】1.句意:如今人类正更加积极地探索太空,每年都有许多火箭被送入太空。主语“Many rockets”和动词send是被动关系,同时结合时间状语“every year”,说明句子时态是一般现在时,因此使用一般现在时的被动语态,主语为复数,be动词用are,send的过去分词为sent。
2.句意:我们发布大量介绍系外行星和太阳能的文章。此处用后置定语修饰名词articles,名词articles和动词introduce是主动关系,因此使用现在分词形式introducing。
3.句意:宇航员在航天器上工作,他们必须互相协作。cooperate with sb.“与某人合作/协作”,with符合句意。
4.句意:他们的主要任务是研究星系和遥远的行星。主语是单数概念,整句描述客观事实,用一般现在时,因此be动词用is。
5.句意:他们使用望远镜和漫游车来收集信息。 use sth. to do sth.“使用某物做某事”,用不定式作目的状语,因此to collect符合句意。
6.句意:一些载人飞船已经登陆火星了。时间标志词already是现在完成时的典型提示词,主语“Some manned crafts”是复数,因此现在完成时结构用have+过去分词,land的过去分词为landed。
7.句意:宇航员会处于失重状态,需要学习如何在太空中操作机器。 “疑问词+不定式”在句中作learn的宾语,how to operate表示“如何操作”。
8.句意:很多人有在其他星球生活的大胆想法,但我们仍然需要做更多的研究。require to do sth.表示“需要做某事”,不定式作require的宾语,to do符合句意。
9.句意:我们不会轻易取消这个计划,因为我们对太空探索抱有极高的期待。前后因果关系,because符合句意。
10.句意:我们期待着有一天能造访其他行星。look forward to“期待”,固定搭配。
