1．I have_lots_of_work_to_do. 我有好多工作要做。
(1)句中不定式to do作work的定语，构成have sth. to do结构。主语I为do这一动作的执行者，所以不定式用主动形式表示被动含义。
He has nothing to eat. 他没有什么东西可吃。
(2)不定式的主动语态表示被动含义的情况：
①当不定式作定语，与其所修饰的名词(代词)有动宾关系，但却与句子主语有主谓关系时，要用主动形式表示被动意义。
Living in the city alone, Peter has no one to turn to when he gets into trouble. 彼特独自一人生活在这个城市里，当他陷入困境时，没有人可以求助。 He has got a pair of glasses to read with. 他阅读时戴一副眼镜。
②当不定式作形容词的状语，和句子主语构成逻辑上的动宾关系时，要用主动形式表示被动意义。这类形容词常见的有difficult, easy, heavy, light, hard, comfortable等。
This question is not easy to answer. 这个问题不容易回答。 Tom is an easy-going person while his brother is hard to get along with.
汤姆是一个很随和的人，而他的弟弟却很难相处。 [名师指津]
当用作定语的不定式为“动词＋介词”时，介词通常不能省略。

(1)本句是一个复合句。主句是由连词not only ... but also ...连接并列谓语的简单句，we wanted to是定语从句，修饰universities。
(2)not only ...but also ...“不仅??而且??”，为并列连词，连接平行结构，即两个句法作用相同的单词、短语或句子。
Shakespeare was not only a writer but (also) an actor. 莎士比亚不仅是位作家，还是位演员。
Not only you but (also) she has to attend the ceremony. 不只是你，她也必须参加典礼。
Not only did he make a promise, but (also) he kept it. 他不仅许下了诺言，而且也做到了。 [名师指津]
①在not only ... but also ...句型中also可以省略。
②连接主语时，动词的单复数形式根据就近原则来确定。 ③连接除主语以外的成分时，若not only位于句首，后面的句子需要使用部分倒装结构，但but also后的句子不倒装。

[语法剖析]
一、真实条件句
真实条件句是指主句中的某一动作或状态是在真实情况下或有可能实现的情形下发生的，可用if和unless引导。
If we can't catch the bus, we will walk there. 如果我们赶不上公交车，就步行去那。 I will not give it up unless (I'm) forced. 除非被迫，否则我不会放弃的。 [名师指津]
在表示真实条件句的复合句中，表条件的状语从句和表结果的主句的谓语都用陈述语气。

①If he has (have) time, he will come.
②I won't_go (not go) to her party unless I am invited. ③If she telephones (telephone), let me know.
④If the weather permits (permit), we'll go on a picnic tomorrow.
二、虚拟条件句
1．三种基本的虚拟条件句
虚拟条件句指的是与事实相反或不太可能实现的事，可分为对现在、过去和将来情况的假设。在表示非真实条件的复合句中，表示条件的状语从句和表示结果的主句的谓语动词要用虚拟语气。 条件从句中的谓语 主句的谓语 与现在事 实相反 一般过去式；系动词be一律用were would/could/should/might＋动词原形
11
与过去事 实相反 与将来事 实相反 had＋过去分词 动词的过去式；should＋动词原形；were to＋动词原形 would/could/should/ might＋have＋过去分词 would/could/might/should＋动词原形 If I were ten years younger, I would start all over again. 如果我再年轻10岁，我会从头开始的。(与现在事实相反) If I had enough money, I would first of all buy myself a computer.
如果我有足够的钱，我会首先为自己买一台电脑。(与现在事实相反，暗含钱不够，现在无法买)
If we had had enough rain last year, we could have gained a good harvest. 如果去年雨水充足的话，我们可能会有一个好收成。(与过去事实相反) If you had worked hard, you would have easily passed the final examination. 如果你当时努力学习的话，就会轻松通过期末考试的。(与过去事实相反) If I should see/were to see/saw him tomorrow, I would invite him home. 如果明天见到他，我会邀请他到我家。(与将来事实相反) If it should be/were fine tomorrow, I would go on a trip. 如果明天天气好的话，我就去旅游。(与将来事实相反) [名师指津]
在虚拟语气中，be的各种人称形式都用were。在非正式的文体中，第三人称单数也可用was，但在If I were you ...句式中，不能用was。
单句改错
①He wouldn't feel so cold if he was indoors.was→were ②If we had started earlier, we couldn't miss the first bus. miss→have_missed ③If it rains, the crops would be saved.rains→should_rain/rained/were_to_rain
2．省略if的虚拟条件句
虚拟条件句中有were，had，should时，可把if省略，而把were, had, should放在主语前，构成倒装结构。
Were I you, I would apply for the job. 如果我是你，我就申请这个工作。 [名师指津]
Were it not for ...“如果要不是??”；Had it not been for ...“当时要不是??”，这两个句型几乎成了固定句式。
Were it not for your help, I would never be a good manager. 要不是你的帮助，我永远也成不了好经理。 Had it not been for you, I would have lost my way. 当时要不是你，我就迷路了。
Should it be fine tomorrow，we would have the sports meeting. 如果明天天好的话，我们就开运动会。
句型转换
①If it were necessary, I might resign. →Wereitnecessary,_I might resign.
②If you had informed me earlier, I wouldn't have signed the contract. →Hadyouinformed me earlier, I wouldn't have signed the contract. ③You could meet the general manager should you come tomorrow. →You could meet the general manager if youshouldcome tomorrow. 3．错综时间条件句
