学习语法，首先要明白什么是主谓宾定状补，什么是系动词，什么是直接宾语，间接宾语，这些是学习语法的基础,掌握英语语法技巧会达到事半功倍的效果。环球博海六级小编特整理了2014年大学英语六级考试辅导之语法提分训练(5)，供同学们学习!

　　Only in this way, can you learn English well.

　　Only after being asked three times did he come to the meeting.

　　如果句子为主从复合句，则主句倒装，从句不倒装

　　Only when he is seriously ill, does he ever stay in bed.

　　eg：I know the girl.

　　The girl comes from Beijing.

　　I know the girl who comes from Beijing.

　　步骤：

　　1.找到两个句子中相同的名词;

　　2.将两个名词中的一个进行替换，若是人，用who替换;若是物，用which替换;that既可以指人，又可以指物;

　　3. 将who 或which引导的句子放在相同名词之后;

　　eg：I like reading books.

　　The books were written by O Henry.

　　I like reading books which were written by O Henry.

　　eg：I planted a tree.

　　The tree is taller than the house.

　　The tree which I planted is taller than the house.

　　1. who/that/which所引导的句子必须放在相同名词之后;

　　eg：The teacher prized the boy.

　　The boy is my neighbor.

　　The boy who the teacher prized is my neighbor.

　　eg：This is the book.

　　You are looking for the book.

　　This is the book which you are looking for.

　　eg：This is the book.

　　You are interested in the book.

　　This is the book which you are interested in.

　　2. 谓语动词(结构)和后面的介词有两种关系：

　　关系紧密&关系疏远;

　　关系紧密：谓语结构和介词合成在一起，联系紧密，不可分割，一旦分割意思就会发生改变;

　　eg：look for, be interested in , look after, look at

　　定语从句中如果谓语结构和介词关系紧密，则介词必须保留在谓语结构的后面，不能做任何位置的改动;如果谓语结构和介词关系疏远，介词一般提到which/who/that的前面;

　　eg: This is the book which you are looking for.

　　This is the book which you are interested in.

　　This is the book in which you are interested.

　　This is the book which you asked for.

　　3. 关系代词和关系副词：

　　eg：Beijing is the place.

　　I was born in the place.

　　Beijing is the place which I was born in.

　　Beijing is the place in which I was born.

　　定语从句中，如果介词+which表示地点，则可以用where替换;

　　Beijing is the place where I was born.

　　eg: I can't forget the day.

　　I join the army on the day.

　　I can't forget the day which I join the army on.

　　I can't forget the day on which I join the army.

　　I can't forget the day when I join the army.

　　判断：This is the mountain village where I visited last year.

　　This is the mountain village in which I visited last year.

　　This is the mountain village which I visited in last year.

　　正确：This is the mountain village which/that I visited last year.

　　4. 判断关系代词和关系副词的方法：

　　(1)不管是关系代词还是关系副词，都取决于从句中的谓语动词;

　　若该谓语动词为及物动词，则一定使用关系代词;若该谓语动词为不及物动词，且其后没有介词，则一定使用关系副词;

　　eg：I will never forget the days when I worked together with you.

　　I will never forget the days when I spent in the countryside.

　　I will never forget the days which I spent in the countryside.

　　(2)通过判断先行词在定语从句中的成分

　　eg：Is this the museum (that ) you visited a few days ago?

　　the museum：充当visit的宾语

　　Is this the museum ( in which/where ) the exhibition was held?

　　关系代词：前面句子里的先行词也要在后面的句子里充当主语或者宾语的成分; 介词+which，恰好表示时间和地点，可以替换成when，where这样的关系副词;
