如果定语从句中缺少主语、宾语，就应考虑使用关系代词。
1. I’ll never forget the days when I spent in New York with you. （when 应改为which 或that，spent 后面缺少宾语，故用关系代词。
）2. I’ll never forget the days which I visited New York with you. （which 改为when，定语从句中有主语和宾语，故使用关系副词）3. Is this the library where you visited yesterday? （where改为that 或which，也可省略，动词visit后缺少宾语，故用关系代词引导定从。
）易错点二：固定句式出差错4. Mary is so lovely a girl as everybody loves her. （as 改为that ; so…that为固定句式，that 引导结果状语从句，该从句的成分是完整的，不缺少主语或宾语）5. Mary is so lovely a girl that everybody loves. （that 改为as . so…as是固定搭配，as 引导定语从句，as 在定语从句中作宾语或主语，类似的固定句式的定从还有the same… as (that) ，such…as ，as…as ）。
易错点三：主谓不一致6. Tom is one of the students who likes swimming. （likes 改为like ; 在“ one of + 复数名词+ 定语从句”结构中，定语从句的先行词是复数名词，故关系代词who=students, 是复数概念。
）7. Tom is the only one of the students wholike swimming.（like 改为likes .在“ the (only) one of + 复数名词+ 定语从句”结构中，先行词是one，而不是复数名词，故关系代词who=one，是单数概念）易错点四：与强调句型及其他句型的混合8. Was it in the shop that you bought the recorder that you lost your pen? （第一个that 改为where，you bought the recorder 为定语从句，其引导词应用where ，后面第二个that 才是强调句中的that ，此句可还原为：You lost your pen in the shop where you bought the recorder .）9. You’d better make a mark at where you have any questions. （去掉at，where 引导地点状语从句）易错点五：特殊名词作先行词时关系词的选取错误10. I don’t like the way which you speak to her. （在which 前加in，或将which 改为that，或去掉which.注意：way 作先行词时，其定从引导词可用that 或in which 或省略）11. I don’t care for pay. I just want to get a job that I can be greatly valued.（that 改为where 或in which .注意：case, club, job，occasion, point, position, situation，system, 等作先行词时，定从常用where 或in which,但最终决定答案的是看定从中是否缺少主语，宾语。
）易错点六：忽略as 和which 引导非限定性定语从句的区别12. He failed in the exam again，which was expected. （which 改为as）13. He failed in the exam again，as was not what he had expected. （as 应改为which）as 和which 虽然都可引导非限制性定语从句，但仍有以下三点区别：( 1 ) as 有“正如;就像”之意，而which 没有;( 2 ) as 引导的非限制性定语从句可置于句首、句中或句末，而which 只能置于句末;( 3 )如果非限制性定语从句是否定句时，只能用which 引导。
易错点七：忽略that 和which 引导限制性定语从句的区别14. This is the most exciting football game which I have ever seen. （which 改为that）15. Here are the samples that— had I thought of it — you could have taken with youyesterday.（that 改为which）析：当先行词被最高级、序数词修饰或先行词本身是不定代词(且指代物)时，只能用that 来引导定语从句，当关系词后面有插入成分时，只能用which 来引导定语从句易错点八：介词前置出差错16. The two things with which Marx was not sure were the grammar and some of the idioms. （with 改为about 或of.在定语从句中前置的介词必须和后面的动词或形容词构成固定搭配）17. Tell him all the things to which he should pay attention. （把to 移到attention 的后面。
并不是所有的固定搭配中的介词都可前置）易错点九：which 和whose 的意义不明确18. The book which cover is broken is of great help to all of us. （which 改为whose）19. The book of whose the cover is broken is of great help to all of us. （whose 改为which）析：关系代词which 不能在定语从句中作定语，但whose 可作定语，“ whose + n ”相当于“ the + n + of which ”或“ of which +the + n ”。

如表时间的先行词不一定用when，表地点的先行词不一定用where，表原因的先行词不一定用why /for which 等。
① Is this the reason ________ at the meeting for his carelessness in his work?A. he explainedB. what he explainedC. how he explainedD. why he explained② This is just the place ________ I am longing to visit these years.A. thatB. whereC. in whichD. to which句①中reason作explain的宾语，可以省略引导词，所以选A，对原因进行解释的内容在句子后面for his carelessness in his work。
