似用法。如：

The problem is worth discussing.
3、作表语
有时的动名词可以和主语调换位置。如：
My hobby is collecting stamps.
Her job is washing, cleaning and taking care of the child.
The film is touching.
4、作定语
动名词作定语，一般表示用途。如：
a waiting room，a diving board，a reading room，a dining hall
there are a lot of swimming pools in the city.
注：（1）现在分词作定语表动作，它与所修饰的名词之间存在逻辑上的主谓关系，可改写成一个定语从句。
如果为单词，放在被修饰n之前，为短语，放在被修饰n之后。
如：a sleeping boy =a boy who is sleeping
a developing country =a country which is developing
（2）动名词作定语通常表示它所修饰的名词的用途或性质，可改写成一个for的短语，两者不存在逻辑上的主谓关系。
如：a washing machine = a mashine for washing
a swimming pool = a pool for swimming
5.作状语
（1）现在分词在句中作时间、原因、伴随、条件、结果等状语。
①时间状语（分词作状语前面可加when, while等）
Hearing the good news, he jumped with greatjoy.
Not having finished her work in time, the boss fired her.
②原因状语
Seeing nobody at home, he decided to leave them a note
③伴随状语
The girls came in, following their parents.
④结果状语
The poor old man died, leaving nothing to his children.
注意：现在分词作状语的几个特性。①时间性。与谓语动词同时发生，用一般时，如发生在谓语动作之前时则用完成式having done。②语态性。与句子的主语之间的关系，是主谓关系或动宾关系。遵循的规则“主动进行，被动完成”。③人称一致性。分词的逻辑主语就是句子的主语。
6. 作宾语补足语：We can see steam rising from the wet clothes.

英语虚拟语气语法归纳总结
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）
过去完成时知识点总结和题型总结(word)
过去完成时知识点总结和题型总结（word） 一、初中英语过去完成时 1．—We all went to the park except you last weekend. Why didn't you come? —Because I the park twice. A. have gone to B. had gone to C. had been to D. have been to 【答案】 C 【解析】【分析】have gone to去了（尚未回）．have been to去过（已回），根据句意在last weekend之前去过，所以用过去完成时，故选C。 【点评】本题考查过去完成时的用法，表示在过去某一时间前已经发生的动作。 2．Sue didn't go to see the film with us last week because she ________________ it with her mother. A. has seen B. had seen C. will see D. saw 【答案】 B 【解析】【分析】句意：苏上星期没和我们一起去看电影，因为她和她妈妈一起看过了。 A.已经看了，现在完成时； B.已经看了，过去完成时； C.将看，一般将来时； D.看了，一般过去时。Sue和妈妈看了电影的影响是上周Sue没有和我们看电影，所以用完成时，根据didn't可知是与过去有关，所以用过去完成时，结构是had+动词过去分词，see的过去分词是seen，故选B。 【点评】考查过去完成时，注意平时识记其结构，理解句意。 3．Jake _____his key in the office so he had to wait until his wife _______ home. A. has forgotten … comes B. forgot… come C. had left… came D. had left…would come 【答案】 C 【解析】【分析】句意：杰克把他的钥匙丢在办公室了，因此他不得不等到他的妻子回家。结合语境可知前文描述的是过去某时前已经完成的动作，故用过去完成时态。下文指的是过去某时的动作，故用一般过去时态。选C。 【点评】英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型，首先要注意句子中的时间状语，如果没有则要通过分析上下文，结合语境来判断句子的时态。 4．When I ______ the cinema, the film _______for ten minutes A. got to; has begun B. arrived at; has been on C. reached; had begun D. hurried to; had been on
可用虚拟语气的用法总结
虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句 If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如： Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三．含蓄条件句

虚拟语气用法总结讲课稿
虚拟语气用法总结
虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达： a. 非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人主观愿望。 b. 与客观事实相反地情景，即强制性虚拟语气，表示建议、命令、劝告这一类的意思上，表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而且一般有明显得标志。 二.虚拟语气的考点为： 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反：从句用一般过去时，主句的谓语用would (could, might) ＋动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反：从句用过去完成时，主句的谓语用would (could, might) ＋现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反：从句用should (were to，did) + 动词原形，主句的谓语用would (could, might) ＋动词原形 If it should/were to snow tomorrow, I would go skiing.
注意：虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…，要是…多好”的语气表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形，其中should 经常被省略。这类动词包括： suggest, propose, recommend, demand, order, command, desire, require, insist,
doing,todo,do的用法

(完整)虚拟语气用法归纳,推荐文档
虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句，表达的是说话人的遗憾后悔的语气，愿望以及建议，命令，要求等等的情感，往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后，有可能出现的情况。 虚拟语气的内容主要有三大模块，第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。 下表就是条件从句虚拟语气的基本用法： 通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢？这就像是数学里的排列组合，一边有三种情况，交叉一搭配就出现了好多种情况。不管怎样，我们要遵循一个原则，就是“各自为政”。例如，从句是对过去情况的假设，而主句则是对现在情况的假设，那我们在使用时，从句就用过去完成式，而主句要用would/could do的形式。当然，也不是所有的AB配就是合理的，有时候在具体语境下，会出现矛盾的情况，这时我们就要结合要表达的意思来判断他们是对什么情况的假设，选择合适的形式。一般而言，主句的假设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现主句的现状。因此在此类的完成句子练习中，我们要特别提醒注意时间状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设，主句是对现在的假设) 5.
