45、ion of all time is the Internetr_参考答案I.单项选择。1D【详解】句意：明天花园里会种些花。A为一般将来时；B为一般现在时的被动句；C为一般过去时的被动句；D为一般将来时的被动句。首先根据时间状语tomorrow，判断句子中的谓语动词用一般将来时，主语Some flowers是动作plant的承受者，所以用被动语态，一般将来时被动语态的构成是：主语+will +be +动词的过去分词。故选D。2B【详解】句意：我妹妹几乎从不吃垃圾食品以便保持健康。so that以便，其后跟句子；in order to为了，跟动词原形；for为了；in order that为了
46、（后面跟句子）。根据keep healthy可知，keep是动词原形，因此排除A/D；for是介词后跟动名词，所以选项C不对。故选B。3A【详解】句意：我认为中国人很快就会实现中国梦。本题是一般将来时，will后跟动词原形，排除C/D；A. realize实现；B. reach到达；结合语境：我认为中国人很快就会_ 中国梦。应该选择realize实现；是“实现中国梦”的意思。故选A。4A【详解】句意：飞向太空的梦想已经实现了。A. come true实现；B. come into being产生；C. come back回来；D. come in进来。结合语境可知，飞向太空的梦想是已经实现了。
47、因此选择come true实现；故选A。5B【详解】句意：我希望乘宇宙飞船去参观其他行星，比如火星。spaceship“宇宙飞船”，是一种交通工具，因此：乘宇宙飞船，用介词by。排除C/D；on在上；like作介词，意为“比如”用来表示举例。语境是：我希望乘宇宙飞船去参观其他行星，比如火星。故选B。6D【详解】句意：如果你继续努力，总有一天你会成功的。A. some days一些天；B. a day一天；C. the day特指的一天；D. one day指将来的某一天。结合语境可知，成功的那一天是不确定的，因此排除C；而且成功了就是一天之际，因此也不用复数。排除A；由will可知，本题是一般
48、将来时，因此选择one day指将来的某一天。故选D。7C【详解】句意：大多数家庭作业将来都将由机器人完成。A为一般将来时；B为一般将来时的被动句；C为一般将来时的被动句；D为一般现在时的被动句。in the future“在未来，在将来”的意思。属于固定短语。排除B/D；在根据时间状语in the future，判断句子中的谓语动词用一般将来时，主语Most homework是动作do的承受者，所以用被动语态，一般将来时被动语态的构成是：主语+will +be +动词的过去分词。故选C。8A【详解】句意：这些书重20多公斤。我拿不动它们。A. weigh重，动词；B. heavy重的，形容词
49、；C. weight重量，名词；D. fat肥的，形容词。本题缺少谓语部分，因此只有动词可以充当谓语。故选A。选项B/C/D不能做谓语。9D【详解】句意：你将会去那里吗？我不能确定。我不知道我是否能够来。根据上句的Will you be there? 空格前面的Im not sure. I dont know if 后接的是宾语从句，后面的come可知，这里谈的come是将来的情况，所以我不知道我是否将能来。be able to do sth. 能够做某事，与will搭配，可以表示“将来能够”的含义。故选D。10C【详解】句意：你借了几本书？ 四本。我昨天借了一本，今天早上又借了三本。A. o
50、ther指另外的人或物；B. the other表示“两个数量中的另一个”，表示特指，总数为俩；C. another只能用于三个或更多的人或物，泛指同类事物中的三者或三者以上的“另一个”，表示泛指。D. others只能作代词，意思是“其它的人、物、事等”，常用来泛指。本文的语境是：我昨天借了一本，今天早上又借了三本。因此选择another“又，再”。故选C。【点睛】another/others/the other/other的用法区别：1. another泛指（指三者或三者以上中的）另一个，既可作代词又可作形容词。做代词时如：I have finished this book, please
51、 give me another.做形容词：I will be back in another ten days.2. other其他的，另外的，泛指另一个另一些。作定语时，常与可数名词复数连用。如：But other creditors have refused the terms,但如果前面有the, some, any, each, every及形容词性物主代词时,可与可数名词单数连用，如every other day。3. others泛指别的，其他人是other的复数形式。相当于other加可数名词复数。 如：She has more concern for others than
52、for herself.4. the other可作代词也可作形容词，表（两者中的）另一个，常用于onethe other 的句型中，如：she has two children, one is a boy, the other is a girl5. the others是the other 的复数形式，特指某一范围内“全部或其余的人或物”，只作代词用，相当于the other 加可数名词复数，如：Four of them are in the classroom, what about the others.11D【详解】句意：美国的人口大约是中国人口的四分之一。本题考查倍数的表达。当两者
53、进行比较时，可以用asas同级比较的结构，也可以用比较级+than结构。倍数的表达是：倍数/分数+asas结构，asas中间用形容词或副词的原形，C选项用了比较级，因此排除；A/B选项不符合倍数的表达方式，所以答案是D。12D【详解】句意：自从中国发射“嫦娥一号”以来，已经有3年了。本题考查句型：It is（has been）+时间+since+持续性动词的过去时”，表示“自从以来到现在已有多久。”本题中的选项A/B的第二个空应该用since，而不用for或with，因此排除；选项C的第一个空用was，那么在since引导的从句中，应该用过去完成时。所以C不对。故选D。13B【详解】句意：这种
54、机器人被用来帮助人们做危险的工作。A. used to过去常常；B. was used to被用来做某事；C. used for用于；D. was used for被用于。for是介词，因此后面跟动名词，help是动词原形，所以排除C/D；主语This kind of robot与use之间存在着被动关系，因此应该用被动句。故选B。14C【详解】句意：青少年不允许在公共场所吸烟。A为动词原形；B为主动语态；C为被动语态；D为一般过去时，主动语态。Teenagers与“allow”之间是被动关系，所以使用被动语态。allow sb. to do sth. 变成被动语态后为：sb. + be al
55、lowed to do sth. 故选C。15D【详解】句意：如果一个人被发现不戴头盔驾驶摩托车，他将受到惩罚。考查一般将来时的被动语态。分析句子可知，if引导的是条件状语从句，遵循“主将从现”的规则，空格所在句为主句，应用一般将来时；主语“a person”和谓语动词punish是被动关系，应用一般将来时的被动语态，结构为will be done。故选D。II. 完形填空。16B 17D 18C 19B 20B 21D 22A 23C 24A 25B【导语】本文是一篇记叙文，讲述了四个学生在课堂讨论上对自己未来想做什么的畅想。16句意：他们正在讨论将来想要做什么。caring about关心
