主谓一致用法总结

主谓一致 使用主谓一致时，必须遵循三个原则，即语法一致原则、意义一致原则和就近一致原则。 一、当单数可数名词、不可数名词、复合不定代词、单个不定式（疑问词＋不定式）、动名词或主语从句以及表示“时间、价值、重量、距离、书名、影片名称”等名词作主语时，谓语动词通常用单数形式。例如： The curtains are closed and the living room is dark when Mom and Dad enter. Visiting a place like this is always very interesting. Why pleasant smells do not reduce pain in men is a question still to be answered by scientists. 二、all（some, a lot, plenty, any, part, the rest, most等）＋of＋名词作主语以及分数、百分数构成短语作主语时，谓语动词单复数形式取决于of后的名词或代词。表示复数概念用复数；表示单数概念用单数。例如： As a result of the serious flood, two-thirds of the buildings in the area need repairing. One study says that 90% of our time is spent watching television

or using computers. While the rest of the passengers were getting out, she glanced at the faces around her. 三、在“名词/代词＋介宾结构＋谓语＋…”结构中，谓语动词与名词/代词保持一致，介宾结构看作插入成分。该结构中的常见介词及介词短语有with, together with, along with, as well as, like, but, except, besides, including等。例如： Healthy eating along with regular exercise is probably the only way to become fit. Nobody but Tom and his father has ever been there. 四、a number of / a group of / a variety of / a total of 等构成短语作主语时，谓语动词用复数形式；而the number of / the group of / the variety of / the total of 等构成短语作主语时，谓语动词用单数形式。例如： The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. Nowadays, a large number of women, especially those from the countryside, work in the clothing industry. 五、quality / pair / amount等构成短语作主语时，谓语动词根据

虚拟语气的用法及经典练习题(附答案)

虚拟语气
概念
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通 过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
应用条件 在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强 烈情感时，也用虚拟语气。即当一个人 说话时欲强调其所说的话是基于自己的主观想法，而不是根据客观实际，就用虚拟语气。 在非真实条件状语从句中的用法 真实条件状语从句与非真实条件状语从句 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设或实际可能性不大的情况，故 采用虚拟语气。 例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴士。 ( 真实 ) If he is free, he will ask me to tell stories. 如果他是空闲的，他会要求我讲故事。 （真实） If I were you, I would go at once. 如果我是你，我马上就会去。 （非真实，虚拟语气） If there were no air, people would die. 如果没有空气，人就会死亡。 （非真实，虚拟语气） 用法及动词形式
从句
主句
If+ 主语 +did 与现在事实相反 （ be 动 词 were ）
主语 +should/would/ could/might+do
主语 +should/would/ 与过去事实相反 If+ 主语 +had done could/might+have done
1.If+ 主语 +did 主语 +should/would/ 与将来事实相反 2.If+ 主语 +were to could/might+do 3.If+ 主语 +should 例句： 1 、表示与现在事实相反的情况： 例： 1. If I were you, I would take an umbrella. 如果我是你，我会带把伞。 （事实：我不可能是你） 如果我知道他的电话号码，我就会告诉你。 （事实：不知道） 1 2.If I knew his telephone number, I would tell you.

虚拟语气和倒装

Subjunctive mood (1) Nevertheless, should a fight follow, neither creature will be badly hurt, for the loser will save himself by making a gesture of submission. (Line 5) (2) If it had not had this disability it would have undoubtedly stayed in the jungle and hunted for food in the customary way. (Line12) If the human population had not increased so rapidly, people would have had more space and freedom. (Line 23) (3) If the caged lion, for example, were free to wander on the grassy plains of Africa, it would be continually active, ranging over long distances, hunting in family groups. (Line 15) 此三类句子体现了虚拟语气的三种时态变化。 （1）第1句中“should a fight follow”是表示将来情况的虚拟语气，意思为“if a fight should follow”，句中省略了“if”，将“should”提前，构成倒装，表示“万一，一旦”的意思。值得注意的是本句中的主句部分未使用虚拟语气。 (2) 第二部分这两句是与过去事实相反的虚拟语气。这类句子，从句用“had +动词过去分词”，主句用“would/should/could/might + have + 动词过去分词”。 (3) 第3句是与现在事实相反的虚拟语气。从句用“did/were”，主句用“would/should/could/ might + 动词原型”。 虚拟语气专项复习： A．虚拟语气在非真实条件状语从句中的用法 1、表示与现在事实相反的情况： if+主语+过去时+其他+主语+should/would/could/might+do+其他 例：If I were you, I would take an umbrella.如果我是你，我会带把伞。 If I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。 If there were no air or water, there would be no living things on the earth. If I had any money with me, I could lend you some. 如果我带钱了，我就会借给你些。（事实：没带钱）If he studied harder, he might pass the exam.如果他再努力些，就能通过考试了。（事实：学习不用功）2、表示与过去事实相反的情况 if+主语+had done +其他+主语+should/would/could/might+have done+其他 例：If I had got there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。 If he had taken my advice, he would not have made such a mistake. 3、表示对将来情况的主观推测 ①if+主语+did/should/were to do+sth.+主语+should/would/could/might+do+其他 ② if+主语+did/be(were)+sth.+主语+should/would/could/might+do+其他 ③if+主语+should+do+sth.+主语+should/would/could/might+do+其他 例：If he should come here tomorrow, I should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。 If there were a heavy snow next Sunday, we would not go skating. If she were to be there next Monday, I would tell her about the matter. 4、有时，虚拟条件句中，结果主句和条件从句的谓语动作不是同时发生时， ①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。 如：If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会成为一个工程师了

(完整版)高一英语“主谓一致”用法归纳

高一英语“主谓一致”用法归纳 一、基本概念 所谓一致关系(Agreement)就是在英语句子中各个成分之间必须在人称、数、性等方面要保持一定的语法关系。在英语中最主要的一致关系是主语与谓语动词之间的一致。在判断一个句子主语、谓语是否一致时，要遵循下列三个原则：语法一致原则、意义一致原则和就近一致原则。一般来说，主语的单复数形式决定着谓语动词需要采用的单复数形式。比较：The student studies very hard.这个学生学习非常努力。The students study very hard.这些学生学习非常努力。 主谓一致的原则说起来简单，但在实际使用中遇到的情况要复杂很多。在处理主谓一致的问题时，可依据上面提到的三个原则。“语法一致”也就是平常说的从语法形式上取得一致，即主语为单数形式，谓语动词亦用单数形式。“意义一致”就是从意义着眼来处理主谓语一致问题。有时，主语形式为单数，但意义为复数，谓语动词依意义而定，也采用复数形式。“就近原则”是指谓语动词的人称和数往往和其最近的主语保持一致。 二、基本用法 1.集合名词与谓语动词的一致 集合名词作主语，如果表示整体概念，谓语动词用单数形式；如果强调其成员，则用复数形式。常用的集合名词有： army,audience,class,club,committee,company,couple,crowd,family,flock,group,government,j-ury, majority,minority,organization,party,personnel,publ-ic,staff,team,union等。 The football team are discussing the problem with the coach now. 足球队员们现在正在与教练讨论这个问题。 The police have caught the criminal.警察已经逮捕了那个罪犯。 The majority were/was for the proposal.大多数人赞同这个提议。 Only a minority of students receive the scholarship.只有少数学生获得了奖学金。 【注意】 （1）有些有生命的集合名词作主语时，谓语动词只用复数。这样的名词常用的有：cattle,people,police,folk等。 The cattle are grazing in the fields.牛在田里吃草。 （2）无生命的集合名词作主语时，谓语动词常用单数形式。这样的名词常用的有:clothing,furniture,machinery,jewellery等。 Warm clothing is necessary in cold climates.气候寒冷的地方需要暖和的衣服。 All the furniture has been moved to another room. 所有家具已经搬到了另一个房间里。 2.由either...or...，neither...nor...，not only...but(also)...连接的两个名词或代词作主语时，主谓一致遵循就近原则，即谓语动词应与最近的一个主语的人称和数保持一致。 Either he or I am wrong.不是他错就是我错。 Not only the students but(also) the teacher is active in sports and games.不但学生，就连老师都积极参加体育运动。 Does neither the teacher nor the students know this matter? 教师和学生都不知道这件事吗？ 【经典回放】 Either you or one of your students ______ to attend the meeting that is due tomorrow.

虚拟语气详解及时态

二、虚拟语气（Subjunctive Mood） 1. 主语从句中的虚拟语气 主语从句（常用形式主语it 来代替，结构为It is that…）中的虚拟语气主要取决于某些用来表示建议、命令、要求、惊异和失望等的形容词和过去分词，其形式为：（should）+ 动词原形。常这样用的形容词有： appropriate，advisable，better，desirable，essential，imperative，important，insistent，natural，necessary，preferable，strange，urgent，vital等。 过去分词有： desired, demanded, ordered, requested, suggested, recommended, required 等。 例如： It is essential that you (should) win the voters’ hearts. It was suggested that he (should) join the club activities. 2. 表语从句和同位语从句中的虚拟语气 在表示建议、命令、主张、目的和愿望等的名词后面的表语从句和同位语从句中谓语动词要求使用虚拟语气。其形式为：（should）+ 动词原形。 常这样用的名词有： resolution, pray, decision, motion, suggestion, preference, proposal, advice, recommendation, desire, demand, requirement, order, necessity, request, idea 等。 例如： He gave orders that the guests (should) be hospitably entertained. 他下令热情款待这些客人。 His proposal is that we (should) get rid of the bad habits. 3. 宾语从句中的虚拟语气 1）某些动词后所接宾语从句中的谓语动词要求用虚拟语气，用来表示建议、命令和要求等。其形式为：（should）+ 动词原形。 常这样用的动词有：ask (要求), advise, determine, decide, command, insist, intend, move, prefer, propose, order, recommend, request, require, suggest, urge, demand, desire, direct等。例如：He insisted that the meeting (should) be put off. 他要求推迟那个会议。 They proposed that all the plans (should) be discussed at the meeting. 他们建议所有的计划都应该在会上讨论。 2）在以it为形式宾语的复合宾语从句中也可以用虚拟语气，其形式为：（should）+ 动词原形。这一句型中使用的形容词（宾补）与主语从句中的虚拟语气所使用的形容词相同。例如： We think it advisable that he (should) think deeply before acting. 我们认为他在行动之前好好考虑一下才是明智的。 3）wish后面所跟的宾语从句中的虚拟语气表示某种不能实现的愿望。 例如： I wish I knew what was going to happen. 但愿我能知道要发生什么事。 She wished she had stayed at home. 她后悔当时不在家。 I wish I were rich. 我巴不得我很有钱。
