revised 非限制性定语从句课件.ppt

Grammar; She has two brothers who are working in the city. 她有两个在这个城市工作的弟弟。 (She has more than two brothers.) b) She has two brothers, who are working in the city. 她有两个弟弟, 他们在这个城市工作。 (She has only two brothers.) ;下面两个句子只有一个逗号之差, 意义大相径庭。 He will wear no clothes which will make him different from others. 他不会穿一些使他显得与众不同的衣服。 b) He will wear no clothes, which will make him different from others. 他不穿衣服, 这会使他显得与众不同。;非限制性定语从句;非限制性定语从句中关系词的指代关系;关系副词(where, when)的指代关系;限制性定语从句和非限制性定语从句 ;2. 非限制性定语从句和主句关系不十分密切, 只是对先行词作些附加的说明, 如果去掉, 主句 的意思仍然清楚。这种从句和主句之间往往用 逗号分开, 不用that引导。非限制性定语从句中, 关系词不可省略。如： Rome, which is the capital of Italy, has a very long history. 意大利的首都罗马历史非常悠久。 b) Yesterday I met Professor King, who came from the University of London. 昨天我遇见金教授, 他从伦敦大学来的。;3.大多数限制性和非限制性定语从句的先行词 往往为某一个词或短语, 而有时非限制性 定语从句的先行词也可为整个主句, 此时非 限制性定语从句常由which引导。 eg. A middle-aged woman killed her husband, which frightened me very much. 一个中年女子杀害了其丈夫, 这事令我十分恐惧。 ; Her brother who is now a soldier always encourages her to go to college.;当我们做非限制性定语从句的练习时, 往往先确定先行词, 然后再分析先行词 在从句中的作用, 再对关系词加以选择。;品读规律;as 在引导非限制性定语从句中，可指代整个主句内容，并有“正如、像……一样”的含义，其位置可放在主句前面，也可放在后面。而which引导的非限制性定语从句只能放在主句之后，且无“正如”之意。 As we all know, he is a famous scientist. As is well known to all, Taiwan is a part of China. 试比较下面两个句子。;介词+关系代词, 介词的选用, 要根据从句的谓语动词的构成。;常与as连用的词有 know, see, expect, point out 等。 as 引导的非限制性定语从句一些固定句型： as has been said before如上所述 ; as may be imagined 正如可以想象出来的那样 ; as is well known众所周知 ; as was expected正如预料的那样; as has been already pointed out 正如已经指出的那样 ; as we all can see 正如我们都会看到的那样 ;1. It’s the same person as we wanted to find yesterday. 我们昨天要找的是同一个人。 2. Such girls as he knows are good at English. 他所认识的女孩都擅长英语。 3. Do you have such books as we like? 你有我们喜欢那种书吗？ 4. She will marry as wealthy a man as she can find. 她将嫁给她能找到的任何一个有钱人。 5. There is so warm a house as we want to live in. 这里有如此暖和的房子，我们都想住在里面。 总结：the same…as; as…as; such…as; so…as 主句中出现the same, as, such, so
