should的详细用法总结

今天给大家带来should的用法，我们一起来学习吧，下面就和大家分享，来欣赏一下吧。

should的用法

should是情态动词，它的基本用法是必须和其他动词一起构成谓语。should后面一定一定要加动词原形。

情态动词没有人称和数的变化。

一，意为"应该....应当.."。

should(应当，应该)用于所有人称，表示劝告或建议。

eg. You should wait a little more.

你应该再多等一会儿。

--- I have a very bad cold.

我感冒很厉害。

--- You should lie down and have a rest.

你应该躺下，多喝水。

二should表示预期，意料之内。

例：The train starts at 6 in the morning, and we should arrive there before noon.

三作shall的过去式使用

在使用情态动词shall的句中，如果出现在含有过去时间的谓语后面的宾语从句中，一般将来时的shall就应该变成过去将来时的should。

例句：He said he should get the money back, whatever the cost!

他说他一定要把钱弄回来，不管付出多少代价。

四表推测

It should be a nice day tomorrow.

明天应该是个好天气。

He should be home by now.

他现在应该在家。

should没有人称和数的变化,其后跟动词原形。如:

You should see a doctor at once.

She should take more exercise.

We / They should drink milk every day.

should的否定式是在should后面加not,可以缩写为shouldn’t,意为“不应当;不应该”。如:

You should not / shouldn’t work on the computer all day.

含有should的一般疑问句是将should提至主语前;其简略回答分别为“Yes,

主语(人称代词)+should.”和“No,主语(人称代词)+shouldn’t.”。如:

—Should I put another spoon of salt into the soup?

—Yes, you should. / No, you shouldn’t.

shall和should

1、shall的用法

(1)shall用于第一、三人称陈述句中，表示说话人征求对方的意见或向对方请示。

(2)shall用于第二、第三人称陈述句中，表示说话人给对方的命令、警告、允诺或威胁。

(3)用于所有人称，表示规章、法令、预言等，可译为“必须”。

2、should的用法

(2)表示有一定根据的推测、推论或可能性，意为“可能，该”(肯定的语气没有must表推测时强)。

(3)多用于疑问句中，表示惊讶、难以相信或不应该的事。

(4)ought to和should的比较

A、ought to也可以表示推论、可能性，和should用法一样。

B、在省略回答中，ought to中的to可以省略。

C、should和ought to表示做正确的事情或理应做的事情。

be supposed to 意为“被期望，应该”，表示被期望发生或根据安排、要求做某事，或认为做某事是正常的。

“should”的用法归纳

一、Should 表示过去将来时，即从过去观点看将来要发生的是，多用于间接引语中。

We thought that we should never see you again. 我们想我们再也看不到你了。

The BBC weather report this morning said that we should have rain.今天早上，BBC电台天气报告说，今天有雨。

They should be there by now，I think. 我估计，他们现在到那儿了。

Should 用于完成时态，表示对过去发生的动作的一种推测，译成“应该已经......”。

三、Should 用于虚拟语气中。

(1)用于It is necessary (important，strange.。。that.。。)中，在美国英语中should 常省去。

It is important that we (should) learn English well. 我们学好

英语很重要。

(2)用于It is ordered (suggested)that.。。中，而在美语中should 常省去。

一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有：（1 ） by + 过去的时间点。如： I had finished reading the novel by nine oclock last night、（2 ） by the end of + 过去的时间点。如： We had learned over two thousand English words by the end of last term、（3 ） before + 过去的时间点。如： They had planted six hundred trees before last Wednesday、 2、由“过去的过去”来判定。过去完成时表示“过去的过去”，是指过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在：（1 ）宾语从句中当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如： She said that she had seen the film before、（2 ）状语从句中

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,

(完整版)非谓语的用法总结

非谓语动词的用法总结李靖非谓语动词（不定式、动名词、分词）不是真正意义上的谓语动词，在句中都不能单独作谓语。但都具有动词的某些特点，可以有自己的宾语或状语，构成非谓语动词短语。不定式表目的，表将来；动名词表主动，表进行；过去分词表被动，表完成。一．作主语( 动名词、不定式、过去分词前面加being, 动名词做主语谓语动词用单数) 1）不定式、动名词都可做主语，但是动名词做主语多指抽象的概念性的动作，可以是多次的经常的行为；不定式多表示具体的动作，尤其是某一次的动作。如： Playing with fire is dangerous. 玩火危险。（泛指玩火） To play with fire will be dangerous. 玩火会发生危险。 2）用动名词做主语的句型: It’s no use/no good/pleasure doing sth 做.......没有用处/好处/乐趣 It’s a waste of time doing sth 做.... 浪费时间 It is worth doing sth 值得做某事 It is no use crying over spilt milk. 覆水难收 It is worth making an appointment before you go. 去之前预约一下是值得的。 3）不定式做主语的句型. It is + adj +for sb to do sth. 比较：表示人的品质时只能用of sb 如considerate/kind/nice/foolish/stupid/rude/cruel /wise/clever/brave/selfish/crazy/good/careful/careless/impolite/right/wrong等单词出现时。 It is silly of you to say so. It is important for us to learn English well. It is a must/ a necessity for us to have a good command of the English language. 4) “Wh- + to 不定式”可做主语。如： When to leave hasn’t been decided yet.什么时候动身还没定呢。 Whether to drive or take the train is still a problem.是自驾车还是乘火车仍是一个问题。 5）一般情况下，不定式和动名词作主语，谓语动词一般用单数形式。如： Seeing is believing.= To see is to believe 眼见为实。 . Planting flowers needs constant watering. 但and连接的多个动名词作主语，谓语动词大多用复数（如果前后动名词的语义一致，谓语一般用单数）。如：Lying and stealing are immoral. 说谎与盗窃是不道德的。 6) 动名词前面可以加上形容词性物主代词构成动名词的复合结构。如： ----- What made him angry? ------ Mary’s /My/His/Her /Their/ The boy’s/ The president’s being late（made him angry. 7being，构成动名词，做主语。如： . Being examined twice a year , driver must obey in this city. 经典练习：

(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. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设，主句是对现在的假设) 8. If Lily didn’t attend today’s party, she could not have the chance to work in the company next week. (从句是对现在的假设，主句是对将来的假设) 9. Had Father followed my travel plan , our family would not stay at home now. (从句是对
