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。
英语四级考试中的虚拟语气
英语四级考试中的虚拟语气英语四级考试中的虚拟语气虚拟语气在宾语从句中的用法是一个常见的考点，我们着重讲一下宾语从句常使用虚拟语气的几类特殊动词，以及这些动词的用法、构成虚拟语气的用法等。
下面是店铺为大家带来的英语四级考试中的虚拟语气，欢迎阅读。
一、何谓虚拟?在英语中，语气(mood)和时态，语态一样，都是谓语动词的一种形式。
表明说话的目的和意图，虚拟语气即表示说话人主观愿望或纯假设情况，动词需用特殊形式。
例如If I were a boy。
其中谓语动词用were，而不是am, shall, was, have等，是因为说话人为女士，而“我是男人”仅是其假设的语气，故用了一个在现实情况中绝不可能用到的were来表达这一虚拟的情况。
通过在I的后面加were这一词，能得知这是虚拟假设出来的情况。
常见的虚拟有两种：1. 表示非真实假设情况：If If I had left sooner, I could have caught the train。
如果早点出发，我就能赶上火车了。
(但我事实上已经错过了，对过去的假设虚拟)He talks so loud as if I were deaf。
他说话声太响，就像我聋了一样。
(但事实我没聋，对现在的假设虚拟)这种情况虚拟时，只需将谓语动词变本身的时态再变过去。
第一句话中的虚拟，本身为过去时，因此再变过去，即过去完成时。
left变为had left, could catch变为could have caught。
第二句话中，as if I am deaf，需要对现在假设，因此变为as if I were a deaf。
(不用I was deaf，避免与真实情况过去式混淆)类似表示非真实情况的`词还有wish希望， suppose假设， would rather宁愿， but for要不是等。
2. 表示建议、命令、要求等主观意愿：He suggested that a petition (should) be drawn up。
英语四级涉及的虚拟语气
一、虚拟语气虚拟语气在考试中比较常见。
尤其是在听力中经常出现。
它主要是表达一种“假设”或者“推测”，而不是客观显示中的真实事件。
因为主要通过动词的变化来反应不同的情况，所以如果不熟悉虚拟语气的基本表示方法，会直接影响听力。
同时翻译中也经常使用。
如果想得高分，要学好这个语法点，争取在翻译部分多拿点分：基本规则：与现在事实相反：If I were you , I would apply for the job.与过去事实相反：If I had taken your advice, I wouldn’t have made such mistake.与将来事实相反：If it rained tomorrow, I would stay at home.真题翻译示例：例1：They requested that _______(我借的书还回图书馆)by next Friday.1. 动词request引导的从句应用虚拟语气2. 虚拟语气的表达方式：should+动词原形，此题则为：should return3. 按句意顺序译，得出答案：I should return the book to library例2：The victim ________(本来有机会活下来)if he had been taken to hospital in time.1. 一看句意有“本来”，十之八九为虚拟语气2. 二看时态推后了，本该过去时，却用过去完成时，因此一定考虚拟3.按句意译为：would have a chance to survive哪些动词及其与他们相关的名词，从句需虚拟语气？一想要(desire)二宁愿(prefer)三命令(order. command)四建议(advice. suggest. propose)五要求(demand. require. request. ask. insist)，另加一个wish实战练习：1. It is strange that he _________ so.A. would sayB. would speakC. should sayD. will speak2. My father did not go to New York; the doctor suggested that he _________ there.A. not wentB. won’t goC. not goD. not to go3.
