英语专四语法之定语从句定语从句是英语语法中的一种重要结构，常常用于修饰句子中的名词或代词，使其更加具体和明确。

下面将介绍英语专四考试中常见的定语从句类型和用法。

1. 关系代词引导的定语从句关系代词包括who, whom, whose, that和which。

它们在定语从句中的作用是代替先行词，并引导一个修饰先行词的从句。

例如： - The man who is standing over there is my father.- The book which I borrowed from the library is due tomorrow.- The car that he drives is very expensive.- The woman whose daughter is in my class is a doctor.2. 关系副词引导的定语从句关系副词包括when, where和why。

它们在定语从句中的作用是引导一个修饰先行词的从句。

例如：- The day when we met was sunny.- The place where we had dinner was very crowded.- The reason why he left the company is still unknown.3. 用于表示数量或序数的定语从句在表示数量或序数的句子中，常常使用定语从句来进一步说明先行词。

例如：- The first person who finishes the race will receive aprize.- The only thing that she wants for her birthday is a new guitar.- The number of students who attended the lecture was more than expected.以上是英语专四语法中关于定语从句的介绍，考生在备考过程中需要多加练习，尤其是在理解和使用不同类型的引导词上。

语法考点之一：虚拟语调考点1. If从句中旳虚拟语调1、与过去事实相反：从句sb had done，主句sb would(should,could,might)+ have done；1.

All of us would have enjoyed the party much more if there ___ quite such a crowd of people there.A. weren’tB. hasn’t beenC. hadn’t beenD. wouldn’t省略if，从句旳语序用到装，即将were,had或should移至主语旳前面，但否认词not不前移。

3. Had Judy been more careful on the maths exam, she ____ much better results now.A. would be gettingB. could have gotC. must getD. would get4. ______you were busy, I wouldn’t have bothered you with my questions. 1994A.

三类从句名词性从句：Nominative/noun clauses1. 主语从句subject clause除基础知识外，另外要掌握的：a. 识别it作形式主语，主语从句后置It is a privilege that you have invited me to the party.b. whether, if引导主语从句的区别c. whatever, whoever, whenever , wherever引导主语从句时，不可以用no matter what/who/when/where替换。

在引导让步状语从句时，可互换。

2. 宾语从句object clausea. 识别it作形式宾语, 宾语从句后置I consider it an honor that you have invited me to your wedding.b. whether, if引导的宾语从句可互换(没有和or not连用时)，但介词后的宾语从句只能用whether, 不能用if. It is a question of whether we should compromise our integrity.c. 不可省略连词that的5种情况可浏览一下，有个印象：两个以上宾语从句，有插入语，直宾, that从句后置，宾语从句是复合句，且复合句中从句位于主句之前。

(if不对)2. 和定语从句的区别: 作句子成分?3. doubt在否定句中带同位语从句时的引导词是that, 在肯定句中一般用whether.I don’t doubt ____ he can finish the task on time.I doubt ____ they can swim across the river.定语从句attributive clause:先行词：antecedent关系代词：relative pronoun限定性restrictive ~，非限定性non restrictive ~1.关系代词that, who, which用法区分;2.只能用that的情况：先行词前有特定的修饰词，不定代词；先行词是人+物的时候；3.关系代词which前可加介词，that前不能加介词；4.as, which引导非限制性定语从句的区别5.定语从句中的谓语动词和先行词保持一致：He is one of the players who are awarded a prize.He is the only one of the players who is awarded a prize.状语从句adverbial clause：时间~ of time，地点~ of place，原因~ of cause，比较~ of comparison，结果~ of result，条件~ of condition，让步~ of concession，目的~ of purpose，1. for fear that, lest引导的目的状语从句要用should do/be:She put an extra blanket over the baby lest/for fear that he should catch a cold.2. as, though引导的让步状语从句；as 要倒装，though可倒装，也可不倒装。
