英语专四语法重点解释
专四语法 可可英语
专四语法可可英语好的，以下是一篇有关可可英语专四语法的文章：可可英语专四语法精讲一、虚拟语气虚拟语气是英语语法中一个非常重要的部分，在专四考试中也是必考的知识点。
虚拟语气用来表示与实际情况相反的情况或者表达主观上的愿望、建议、猜测等。
虚拟语气的用法包括与现在事实相反、与过去事实相反和与将来事实相反三种情况。
1. 与现在事实相反：使用动词的过去式（be动词用were），从句使用would+动词原形。
例如：If I were you，I would choose to study abroad.（如果我是你，我会选择出国留学。
）2. 与过去事实相反：使用“would+have+过去分词”，从句使用“had+过去分词”。
例如：If we had known the answer，we would have told you.（如果我们知道答案，我们早就告诉你了。
）3. 与将来事实相反：使用“would+动词原形”，从句使用“were+to+动词原形”或者“should+动词原形”。
例如：If it were to rain tomorrow，the football match would be postponed.（如果明天下雨，足球比赛就会被推迟。
）二、定语从句定语从句是英语语法中的另一个重要知识点，也是专四考试的重点。
定语从句用来修饰名词，通常放在所修饰名词之后。
引导定语从句的关联词包括that、which、who、whose等。
1. 使用that的情况：当先行词为all、something、nothing、this等不定代词时，或者先行词被形容词最高级修饰时，多用that引导定语从句。
例如：This is the most interesting book that I have ever read.（这是我读过的最有趣的书。
）2. 使用which的情况：当引导词前面有逗号或放在句末时，通常使用which。

Eg. If it should rain tomorrow, we would not be able to have the sports meeting.=Should it rain tomorrow, we should not be able to have the sports meeting.省略if 的虚拟法（倒装）(2)Eg. Whether it (may) be fine or rainy, we would have the sports meeting. =Be it fine or rainy, we would have the sports meeting.If she had been given more information, she could have answered the questions.=Had she been given more information, she could have answered the questions.第二部分详解&总结虚拟语气的动词标志―insist, suggest, require, request, demand, propose, prefer, maintain, move,urge, recommend, command, order‖等动词表“建议、愿望”时，其后宾语从句中谓语动词要用虚拟语气。

高校英语专业四级考试·词汇语法详细解
高校英语专业四级考试·词汇语法详细解高校英语专业四级考试·词汇语法详细解形容词层迭修饰时的顺序几个属于不同层次的形容词作修饰语时，其词序一般按下列顺序排列：限定词→表示说话人评价的形容词→表示大小、形状、新旧的形容词→表示颜色的形容词→表示国别、来源、材料的形容词→表示用途或目的的形容词→名词中心词。
例如：the town’s charming old English churcha wellknown German medical schoolthe man’s first two interesting little red French oil paintings 近义词辨析bother, disturb, trouble, worry这组词均含有“不停地烦扰他人或搞得某人心神不宁”的意思。
botherdisturb常用于主动和被动两种形式中。
用于被动时，bother指常受到时有时无的小事的烦扰。
用于主动时，bother的意思比disturb强，带有故意打扰他人的意思。
If you return me the book, I will stop bothering you.你归还我的书后，我就不打扰你了。
disturb用于被动形式时，意思比bother强烈，有时甚至可指精神错乱。
用在主动形式时，意思最弱，指某人无意中打扰他人，这种打扰行为并非存心冲着他人去的。
The man was mentally disturbed.这个人精神错乱了。
trouble和worry主要用于被动，指被某事搞得心神不宁。
trouble比worry稍正式些，指麻烦别人一件事而影响他人舒适、方便、效率、健康或心境的平静等。
May I trouble you for the book?麻烦您把书递给我好吗?worry主要指因对某事的结果没有把握而焦虑不安，还可指某人沉浸在软弱无助的情绪或思虑中。
Worrying about your health can make you sick.经常担心你的健康，会使你生病的。
英语专四语法总结
英语专四语法总结1.主谓一致就近原则1.由并列结构或连词（either…or，neither…nor，not…but，not only…but also，or 等）连接的并列主语，谓语动词与靠近的那个名词或代词保持一致。
2. 在倒装句和there be句型中，谓语动词与后面的第一个主语保持一致。
例句：There is a book and some pens on the desk.桌子上有一本书和几支钢笔。
3. 在强调句中，连接代词又在句中作主语，这时它应与被强调的主语保持一致。
例句：It is Ma ry’s brother who was injured in the car accident. 是Mary的哥哥在车祸中受伤了。
意义一致原则1. 当主语与谓语动词之间插入along with，with，as well as，together with，no less than，besides，except，but，including 等短语时，谓语动词不受这些插入语的干扰，依然和主语保持一致。
例句：I, along with my sister, am going to Shanghai next month.我，还有我姐姐，打算下个月去上海。
2. 英语中有一类单、复数同型的词（people，means，sheep，deer，fish 等），其单、复数取决于它在句中的含义。
例句：All of the people in the country have been prepared for thegreat reformation.这个国家的人都已经为大变革做好了准备。
3. 多数情况下，由“what”引导的名词性从句作主语时，其后的谓语动词通常用单数形式。
我只想说：“多保重！”例句：What I want to say is just “ Take care!”．4. 当主语与all，none，any，some等不定代词、形容词连用时，应根据具体句意，来决定其后的谓语动词的单复数。
专四语法点讲解2
二、不定式
1.不定式做主语 (1)引导逻辑主语的介词：不定式的逻辑主 语一般由介词for引导,但下列表示人的性格 行为特征的形容词做表语时, 不定式的逻辑 主语则由of引导：
absurd, bold, brave, courageous, careful, careless, clever, wise, foolish, silly, stupid, good, nice, kind, thoughtful, considerate, greedy, generous, honest, modest, polite, rude, cruel, selfish, lazy, wicked, wrong。 如： Experts say walking is one of the best ways for a person to stay healthy. It’s clever of you to have invented such a device.
The vocabulary and grammatical differences between British and American English are so trivial and few as hardly to be noticed. (3)不定式做结果状语只能出现在句子的末 尾，表示不愉快的结果，有时用only加强语 气。 常见的不定式动词有find, hear, see, be told, form, give, make, produce等。如： Greatly agitated, I rushed to the apartment and tried the door, only to find it locked.
(4)表示方式、原因、时间、机会、权利等 名词用不定式做定语，这些名词包括： way, method, reason, time, place, chance, occasion, opportunity, evidence, power, right, movement, drive (运动)，effort等。如： I worked so late in the office last night that I hardly had time to catch the last bus. We appreciate your efforts to bring about a comprehensive solution to the existing problem. (5)不定代词something, nothing, little, much, a lot习惯上用不定式做定语。如： Though we have made great progress, there is still much to be improved.
