【答案】A

【解析】

【详解】

考察句子语序。句意：在这重大决议之后会出台一系列的办法来支持海南深化改革和扩大开放。In no time（立刻，马上）位于句首，句子用陈述语序，不用部分倒装。另外，该句陈述的过去的事情，因而用一般过去时，综述选A。

【点睛】

关于部分倒装。部分倒装，也叫不完全倒装，指的是谓语部分的be动词，情态动词或助动词放在主语之前的结构。常见的部分倒装分以下几类：第一，否定性副词或者赋词短语，比如seldom，hardly，at no time, in no case, on no occasion等位于句首时，比如，Hardly does he get late. 第二，only修饰副词性短语谓语句首时，比如only in this way can we succeed.而本题中in no time (立刻，马上)，不是否定意义的短语，故不用部分倒装。

6．A rescue worker risked his life saving two tourists who ________ in the mountains for two days.

A．are trapping B．have been trapped

考查语态和时态。句意：一个救援人员冒着生命危险挽救了两个被困在山里两天的旅游者。“who ___ in the mountains for two days”是定语从句，修饰two tourists，two tourists和trap之间是被动关系，该空应用被动语态。由risked可知，营救人员救游客是过去的事情，被困两天发生在营救人员救了他们之前，即“过去的过去”，该空应用过去完成时态。综上，D选项正确。

点睛：过去完成时表示过去某一时间或动作以前已经发生或完成了的动作，即“过去的过

去”，其表达形式为had done，被动语态的表达形式为had been done。

学生们一直在刻苦学习功课，他们的努力终将会得到回报。综上，用一般将来时的被动，故选D。

【点睛】

一般将来时

1. 表示未来的动作或状态常用will / shall + 动词（常与表示将来的时间状语边用如tomorrow、next week等）。

2. 表示一种趋向或习惯动作。

If it is fine, we are going to go fishing.(错误)

(3)be to do sth.表按计划、安排即将发生的动作，还可表示吩咐、命令、禁止，可能性等。例如：A meeting is to be held at 3:00 o’clock this afternoon.

(4)be about to do sth.表示“即将/正要去做某事”，通常不与时间状语连用，但可与when引导的从句连用，构成常考句型：sb was about to do sth when sb did sth。

23．If the new safety system _______ to use, the accident would never have happened. A．had been put B．were put C．should be put D．would be put

【答案】A

【解析】

【分析】

【详解】

考查虚拟语气。句意：如果这个新的安全系统被投入使用过的话，这个事故就不会发生了。根据主句确定是对过去情况的虚拟，所以从句谓语用had done形式，此外根据句意可

知是被动，用被动语态，故A项是正确的。

【点睛】

英语中的三种语气，语气是动词的一种形式，用来说明我们对自己的话所采取的态度。陈述语气（疑问，否定，肯定，感叹）祈使语气（命令，要求，建议，警告）虚拟语气：不可能发生的事，愿望，建议，与事实相反的假设等.虚拟语气在条件中的具体用法真实条件句If you work hard,you’ll surely pass the exam.虚拟条件句（假设情况不存在，实现机会很小）If I were a bird, I could fly freely in the sky.if从句的谓语动词主句谓语动词1.与现在事实相反动词过去式（be一律用were）would/could/might/should+动词原形2.与过去事实相反had donewould/could/might/should+have done3.与将来事实可能相反a.动词过去式（be一律用were）b.should+动词原形（不能用would）c.were to+动词原形

would/could/might/should+动词原形与现在事实相反if从句：动词过去式（be---were）主句：would/could/might/should+动词原形If we had time, we would go with you.If I were you, I shouldn’t do that.If it weren’t raining, we wouldn’t stay.与过去事实相反if从句：had done主句：would/could/might/should+have doneIf the teacher hadn’t helped us, we couldn’t have succeeded.I could have done it better if I had been more careful.If he hadn’t been ill, he might have come.3.与将来事实可能相反if从句：a.动词过去式（be一律用were） b.should+动词原形（不能用would） c.were to+动词原形主句：would/could/might/should+动词原形If he came tomorrow, I would tell him everything.If it should rain tomorrow, I would stay at home and watch TV.If it were to snow tomorrow, they would not go out.Should he come tomorrow, please give the book to him.错综时间条件句在虚拟语气中，有时条件从句动作发生的时间和主句动作发生的时间是不一致的，称为错综时间条件句。这种句子的形式往往要根据句子的时间相调整，分别处理。If you had spoken to him yesterday, you would know what to do now.If you had followed the doctor’s advice then, you would be all right no w.If you had watered them more, the crops would be growing still better now.(有时时间会省略）含蓄条件句有时虚拟条件不用if条件从句，而用介词或介词短语来表示。They would not be able to live without him.（如果没有）He would have failed but for his teacher’s timely advice.（要不是）=if it had not been forIf only you had worked with greater care!(要是......就好了）You would have done the same thing in her position.With a little more care you could have avoid the traffic accident.虚拟结合条件句在虚拟语气中，假设的情况有时间可以通过上下文或其他方式表现出来，并且虚拟的情况和真实的情况同时存在。I was ill that day. Otherwise, I would have taken part in the singing competition.（实------虚）=I was ill that day. If I hadn’t been ill that day, I would have taken part in the singing competition.He would have bought the piano, but he didn’t have enough money.（虚------实）=He would have bought the piano if he had had enough money, but in fact he didn’t have enough money.省略if倒装条件句在虚拟语气中，if 从句假设的情况中如果有助动词had, should和were，那么可省略if，把had, should和were放在句首构成倒装，简称省略if倒装条件句。If he had finished the work yesterday, he would have gone to the concert with you.=Had he finished the work yesterday, he would have gone to the concert with you.If I were you, I wouldn’t do that.=were I you, I wouldn’t do that.If I should meet him, I would tell him about it.=Should I meet him, I would tell him about it.

24．More expressways ________ in Sichuan soon to promote the local economy.

A．are being built B．will be built

C．have been built D．had been built

【答案】B

【解析】

【详解】

考查时态。句意为：四川将建设更多的高速公路以促进当地的经济。根据时间状语soon可知，考查了将来时。英语中的时态是靠动词的变化来体现的，在具体做题时，需要关注的是时间状语。因此，考生在做本题时，需要先找出时间状语soon，然后才能准确判断时态是一般将来时。通过观察选项可知，选项A是现在进行时；选项B是一般将来时；选项C 是现在完成时；选项D是过去完成时。故选择B。

【详解】

考查时态。句意：《时代》周刊将“守护者”——一群因自己的工作而成为受攻击目标的记者评为年度人物，因为冒巨大的风险追求更伟大的真理。根据句意可知，记者被攻击，且已发生，有对现在的影响，所以用现在完成时。故选D。

26．The accident which left 15 people on board dead ________ if both the angry female passenger and the bus driver had kept calm.

A．should have avoided B．should be avoided

C．could have avoided D．could have been avoided

【答案】D

【解析】

【详解】

考查“情态动词+完成式”。句意：如果愤怒的女乘客和巴士司机保持冷静，这起导致15人死亡的事故本来是可以避免的。could have done“本来能做而没有做”，且句子主语The accident和谓语动词avoid之间是被动关系，结合句意可知答案为D。

【点睛】

情态动词+ have done结构：

1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测，语气比较坚定，通常只用于肯定句。如：It must have rained last night,for the ground is wet.

2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用

于否定句和疑问句，could的语气较can弱。如：He can't have finished the work so soon. 3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测，might的语气比may弱一点。这种结构主要用于肯定句和否定句，疑问句改用can或could。如：They may not have known it beforehand.

4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情，或过去做某事纯属多余。如：I needn't have bought so much wine—only five people came.

5.“should / ought to + have + 过去分词”表示过去本该做某事但没做，其否定式表示过去不该做某事但做了，这种句式含有不满或责备之意，ought to的语气比should强一些。如：You ought to / should have studied harder. 你本应该更努力学习的.（但没有）

He oughtn't to / shouldn't have done that. 他本来就不该做那件事.（可是做了）

6.“would ＋ have ＋过去分词”表示对过去的某种情况进行猜测，或本来要做某事却因某种原因未做成，通常用来说明某一情况，但不像用should或ought to那样含有责备之意。如：

I guess the poet would have been about twenty when she wrote her first poem.

Another worker wouldn't have acted like that.

28．They realized that the problem Ted put forward was difficult _______.

A．to solve B．solved C．to be solved D．solving

【答案】A

【解析】

【详解】

考查非谓语动词。句意：他们意识到泰德提出的问题很难解决。结合短语be difficult to do sth.“难以；很难……”后跟不定式，且在此结构中，若主语与其后的不定式为动宾关系，那么该不定式习惯上要用主动形式表示被动意义。故用to solve形式。故选A。

29．Please don’t stand up in class un til you ______.

A．were told to B．are told

C．are told to D．were told

【答案】C

【解析】

【详解】

考查省略句。句意：直到有人叫你站起来，你才可以在课堂上站起来。在一定的上下文中，为了避免重复，动词不定式在句中可以被省略掉，但是要保留动词不定式的符号to。分析句子可知，本句为一般现在时。故C选项正确。

【点睛】

to代替不定式

在一定的上下文中，为了避免重复，动词不定式在句中可以被省略掉，但是要保留动词不定式的符号to。to代替不定式，常同refuse, want, seem, intend, expect, hope, like, be afraid, prefer, care, oblige, forget, wish, try，tell等动词连用。

注意：如果不定式中含有be, have,或have been，一般要保留be, have或have been。

本句还原为：Please don’t stand up in class until you are told to stand up。省略句为：Please don’t stan d up in class until you are told to 。故C选项正确。

30．—Why didn’t you attend the assembly this morning?

—But I ________ anything about that.

A．didn’t tell B．haven’t told C．hadn’t been told D．haven’t been told 【答案】C

【解析】

【详解】

考查时态和语态。句意：——你为什么没有参加今天早上的集会？——没人告诉我。主语I 和tell之间是动宾关系，故用被动语态，又“没有告诉”的动作发生在今天早上之前，即过去之过去，故用过去完成时的被动语态，即had been done，故选C项。

31．People believe that the China Dream is not very difficult ________ so long as the whole nation works hard for it.

A．realizing B．to be realized

C．realized D．to realize

【答案】D

【解析】

【详解】

考查固定句型和语态。句意：人们相信只要全国人民一起努力中国梦不难实现。be difficult to do 结构中，若主语与其后的不定式为动宾关系，那么该不定式习惯上要用主动形式表示被动意义。如：She was difficult to understand at times. 有时候她很不容易理解。能用于此结构的形容词主要有convenient, dangerous, difficult, easy, hard, impossible, interesting, nice, pleasant, safe, unpleasant等。这类结构的特点是句子主语必须是其后不定式的逻辑宾语。故选D。

32．We won’t start the work until all the preparations __________.

A．are being made B．will be made

C．have been made D．had been made

【答案】C

【解析】

【详解】

考查动词时态辨析。句意：我们得等到所有的准备工作都做好了才能开始工作。are being 是现在进行时的被动形式；will be made是一般将来时的被动形式；have been made是现在完成时的被动形式，用于强调动作产生的影响；had been made是过去完成时的被动形式。本题是主将从现的用法。主句是将来时时，从句用现在时或相当于现在的时态；现在完成时强调过去对现在的影响或动作从过去一直持续到现在。故选C。

【点睛】

通常说来, 在时间状语从句中使用一般现在时代替将来时，前面的主句中使用将来时。在高中英语中也使用现在完成时代替将来时，表示到将来某个时间已经完成的事情。主句是We won’t start，从句用一般现在时或者现在完成时，故选C。

33．As is expected, it will be not long before our domestically built aircraft Carriers _____ into operation.

A．will be put B．are put

C．will have been put D．have been put

【答案】B

【解析】

34．You’d better communicate with each other sincerely, and I hope to see your conflict

________ tomorrow.

A．was to be solved B．has been solved

C．will have been solved D．had been solved

【答案】C

【解析】

【详解】

考查时态和语态。句意：你们彼此之间最好真诚地沟通，我希望明天你们的冲突能得到解决。由时间状语tomorrow可知，此处应用将来时，conflict和solve之间为被动关系。因此C项的将来完成时符合语境，表示在将来某一时间以前（明天结束之前）已经完成的动作。故选C项。

【点睛】

本题难度适中。动词的时态和语态放在一起考查增加了试题的难度，需要考生有分析理解复杂的句子结构的能力，必须会根据语境或已给动词的形式来判断动词的时态。如本题中，因为今晚将发生的事，所以应用将来时，it代替concert，它与broadcast之间是被动关系，应使用一般现在时的被动语态。故选A。

【详解】

考查主谓一致和动词时态语态。句意：所有可能的方法都被用来防止空气污染，但天空仍然不明朗。means当名词解释为"方法"，单复数同型，且every+主语，谓语动词用单数；means与动词use之间是被动关系，根据语境“所有的方法都用了”，应该用现在完成时的被动语态。故选D。

【点睛】

“each/every+单数名词+and+单数名词”等结构作主语

当“each/every+单数名词+and+单数名词”或“each/every+单数名词+and+ each/every+单数名词”结构作主语时，谓语动词通常用单数形式。如：

Each boy and each girl has been invited to the teaparty. 每个男孩和每个女孩都被邀请参加茶话会。

The boy and the girl each have their own toys. 这个男孩和这个女孩都有他们自己的玩具。
