定语从句的做题方法: 1. 确定先行词. 判定是人还是物, 即有人又有物用that. 2. 看定语从句缺少什么成分. 缺少主,宾,定语用关系代词; 缺少状语,用关系副词. 3. who/ which /that 在定语从句中作主语时,谓语动词的单复数要和先行词保持一致。 4. 定语从句一般放在所修饰的先行词后面. I am interested in everything (that) he told you yesterday. 5. 非限制性定语从句中只用which, who, whom不用that. ( Beijing, which is the capital of China, is very clean and beautiful. )
先行词为人时: 定语从句缺少主语时用who, that; 缺少宾语时用whom, who, that且可以省略; 缺少定语时用whose.
先行词为物时: 定语从句缺少主语时用which, that; 缺少宾语时用which, that且可以省略; 缺少定语时用whose. 缺少状语时用when, where, why.
先行词为人+ 介词+ whom 先行词为物+ 介词+ which
有些情况下,只宜用 that,不宜用which. 1.先行词是形容词最高级或它的前面有形容词最高级时。 This is the best beer that I have ever drunk. English is the most difficult subject that you will learn during these years. 2先行词是序数词,或它前面有一个序数词时。 He is the last person that I want to see. It is the first time that I’ve ever been here.
还有什麽问题吗
追问非限制性与限制性定语从句有时候which that 总是搞不清。或者有介词之类的什么可用什么不可用
追答7. 先行词前面有the only, the very, the last, no, one of, 等修饰时。 Li Ming is the only one that got full marks in our class. Li Ming is the only one that wants to be a teacher. Li Ming is one of the students that want to be teachers in our class. 8.有两个定语从句,其中一个关系代词已用which,另外一个宜用that. Edison built up a factory which produced things that had never been seen before.
有些情况下,只宜用which,不宜用that. a.先行词为that, those时,用which, 而不用that.例如:What’s that which is under the desk? 在桌子底下的那些东西是什么? b.关系代词前有介词时,一般用which,而不用that. 先行词为人时, 介词后只用whom,不用who, that. 例如:This is the room in which he lives. 这是他居住的房间。 c.引导非限制性定语从句,用which, 而不用that. 例如:Tom came back, which made us happy. 汤姆回来了,这使我们很高兴。
