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 now.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.

18．Don’t worry. The hard work that you do now _____ later in life. A．will be repaid C．has been repaid 【答案】A 【解析】
试题解析：考查时态辨析。根据句子末尾出现的时间状语later in life意为在以后的生活中，可以判断为将来时态，此处要注意的是不要被前文的now混淆，that you do now在句中充当the hard work的定语成分，与句子时态无关。故此处为将来时态。句意：不要担心，你现在付出的努力在以后一定会有所回报。故选A。 考点：考查时态辨析。
B．was being repaid D．was repaid

考查动词的时态语态。句意：这种布销路很好，已售出大量。sell/wash/burn 等词在表示事物的状态、特点时，可以用主动表被动，因此第一个空应选 sells；第二空表示“出售，卖”的动作，用被动语态，且强调对现在的影响应该用现在完成时态，故正确答案为C。
B．is sold; has been sold D．sells ; has been sold

本题考查方向涉及到动词的语态和主谓一致，首先要把握句意，判断主谓之间是主动还是被动关系，再者就是考查学生的考虑是否全面，即加之判断谓语动词的单复数，考查了学生对主谓一致中就前一致的把握。
21．In the 1980s in this village, there were only muddy roads to the outside, and concrete ones ________ yet. A．haven’t built 【答案】D 【解析】 【详解】
考查动词时态及语态。句意：在20世纪80年代，这个村庄只有泥泞的道路通往外面，混凝土的道路还没有建成。根据语境可知，“混凝土的道路还没有建”表示的动作发生在“there were only muddy roads”这一过去的动作之前，属于“过去的过去”，应使用过去完成时；build与concrete ones是逻辑动宾关系，应使用被动语态。故选D。
B．haven’t been built C．hadn’t built
D．hadn’t been built

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。
B．will broadcast D．is broadcasting

C．put
D．has put
【详解】

24．The students have been working hard on their lessons and their efforts _____ with success in the end. A．rewarded C．will reward 【答案】D 【解析】 【分析】 【详解】
本题考查时态和语态。解题步骤：1. 确定时态：根据句尾的in the end可知，事情发生在将来，用将来时。2. 确定语态：efforts和reward是被动关系，应该使用被动语态。句意：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。 例如：We’ll die without air or water.
3. 表示趋向行为的动词如come, go, start, begin, leave等词常用进行时的形式表示将来时。 4. be going to与will / shall, be to do, be about to do用法及区别： (1)shall / will do表示未事先考虑过，即说话时临时作出的决定。
(2)be going to 表示现在打算在最近或将来要做某事，这种打算往往经过事先考虑，甚至已做了某种准备；be going to 表将来，不能用在条件状语从句的主句中；而will do则能，表意愿。
例如：If it is fine, we’ll go fishing.(正确)
B．were rewarded D．will be rewarded
