2016英语专四语法重点解析：定语从句

　　7.关系副词(=介词+关系代词)：

　　例：I shall never forget the day when (=on which) we first met.

　　我永远也不会忘记我们第一次见面的那一天。

　　The rain came at a time when (=at which) it was not needed.

　　雨下得不是时候。

　　This is the computer where (=by/on which) he has stolen top-secret documents.

　　这就是他用来盗窃绝密文件的计算机。

　　Here is the place where (=at which) the murder took place.

　　这就是谋杀发生的地方。

　　He didn’t give any reason why (=for which) I had been fired.

　　他没给任何解雇我的理由

　　This is the house in which (=where) my parents used to live.

　　这就是我父母以前住过的房子。

　　注意事项：

　　(1)在非正式场合， that有时可用来代替关系副词或相当于关系副词的“介词+which”，而且经常全部省略，

　　如：In all the years that (=when/during which) I was at collage

　　在我读大学的那些年里

　　the reason that(=why/for which)he is not happy

　　他不高兴的理由

　　The direction(that)(=in which )the heavenly bodies move can’t be changed.

　　天体运行的方向是不可改变的。

　　He is unpopular because people don’t like the offensive way (that)(=in which) he talks.

　　他不受欢迎的原因是他说话的方式让人讨厌。

　　(2)是用关系代词还是用关系副词：

　　关系词(包括关系代词和关系副词)是学习英语定语从句的关键。用关系代词还是用关系副词，一要看关系词在从句当中作什么成分;二要看关系词所代表的是人、物、时间、地点还是原因;三要看所引导的是限定性定语从句还是非限定性定语从句。所以同样的先行词会有不同的关系词，这是因为关系词在从句当中担当的作用不同而决定的。

　　如：This is the room where/in which we’ll celebrate the New Year.

　　这是我们将要在里面庆贺新年的房间。(充当地点状语)

　　This is the room(that /which)we’ll celebrate the New Year in.

　　这是我们将要在里面庆贺新年的房间。(充当介词宾语，可省略。)

　　This is the room which /that will be used for the celebration of the New Year.

　　这是那个将要被用来庆贺新年的房间。(充当主语)

　　This is the room (which/that) we’ll use for the New Year dinner party.

　　这是我们将要用来举行新年晚宴的房间。(充当宾语，可省略。)

　　The reason (that /which) he had given was not sound enough.

　　他给的理由不够充分。(充当宾语，可省略)

　　The reason why/for which he had done that was not sound enough.

　　他做那件事的理由不够充分。(充当原因状语)

　　This is the house where she lives.这是她住的房子。

　　【比较：This is the house (that/which) she has bought. 这是她买的房子。This is the house that/which I’ve told you is extremely expensive.这就是我和你说过极其昂贵的那幢房子。】

　　I met him in the year when I was first in Xi’an.

　　我刚到西安的那年遇到了他。

　　That is the reason why he did not come that morning.

　　那就是那天上午他没来的原因。

　　(3)定语从句中的时态。如果主句是一般将来时或过去将来时，从句的动作与主句的同时发生，那么该从句要用一般现在时表示一般将来时、用一般过去时表示过去将来时。

　　例：Anyone who/that touches the wire will get an electric shock.

　　任何碰这根电线的人将受到电击。(不用will touch)

　　I would give her anything that she asked for.

　　她要什么我就给她什么。(不用would ask)

　　The first person who/that opens the door will get a shock.

　　第一个开门的人将被吓一跳。(不用will open)

　　There will be a special price for anybody who orders a suit in the next two weeks.

　　任何人在下两周内定做套装都将享受优惠价格。(不用will order)

　　但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，

　　如：Those who will go abroad for training next year will start learning English tomorrow.

　　那些明年出国受训的人员，将从明天开始学习外语。

　　注：①先行词有最高级形容词修饰时，常用that，而不用which：

　　例：Edison was one of the greatest inventors that ever lived.

　　爱迪生是曾经有过的最伟大的发明家之一。

　　This is the best film that I’ve ever seen.

　　这是我曾经看过的最好的电影。

　　She was the greatest woman that/who has ever lived.

　　她是曾经有过的最伟大的女人。

　　②先行词有the same, the very, the first, the last, all, no, the only, much, little, none, any, every等时，常用that, 而不用which：

　　例：He was the first man that we saw in the village.

　　他是我们在那个村子里看到的第一个人。

　　There is little that is interesting.

　　没什么令人感兴趣。

　　I still remember the first time that we met.

　　③当先行词既有人又有物时，用that，不用which，

　　我们参观过的工人及他们的工作条件留下了深刻印象。

　　We listened to him talk about the men and books that interested him。

　　我们听他谈论他感兴趣的人物和书籍。

　　④在same和such之后，定语从句用as引导，

　　让我们只讨论与我们有关的问题。

　　I’ve never heard such stories as he tells.

　　我从来没听说过他讲的这种故事。

　　I shall be surprised if he does this in the same way as I do.

　　如果他做这件事的方法和我一样，那就奇怪了。

　　She works in the same office as I do.

　　Such machines as are used in our workshop are made in china.

　　我们车间使用的这种机器是中国制造的。

　　但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，

　　注：④在same和such之后，定语从句用as引导，

　　偶尔，the same 后面也用that，

　　如：He’s wearing the same suit that he wore at Mary’s wedding.

　　他穿着与他在Mary的婚礼上穿的一样的衣服。

　　She works in the same office that I do.

　　她和我在同一个办公室工作。

　　This is the same watch that I have lost.

　　这块表和我丢的那块一样。

　　as 引导非限定性定语从句即可放在主句之前，也可放在主句之后，用来修饰整个句子。当as在从句中作主语时，后面常接下列句型。如：as is known, as is said, as is reported as is announced 等。

　　例如：As we all know, Mr. Wang is a good teacher.

　　As is known to all, the earth revolves round the sun.

　　He is tired, as you can see.

　　As I expected, he didn’t believe me.

　　As 引导非限定性定语从句时与which的区别：当主句和从句语义一致时，用as;反之，用which。

　　如：He made a long speech, as was expected.

　　He made a long speech, which was unexpected.

　　Tom drinks a lot every day, which his wife doesn’t like at all.

　　(3)但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，

　　注：⑤在“介词+关系代词”的结构中，也可用复杂介词，如：by means of (用，依靠)，as a result of (作为结果)等：

　　例：I have three children, one daughter and two sons, all of whom graduated from the same university .

　　她当时正发烧，所以考试失败了。

　　He is the man from whose house the picture was stolen.

　　注：⑥一个先行词后面可以跟一个以上的定语从句，这种现象叫双重关系从句：

　　例：Here are some words which are often used but which are very confusing.

　　这里有些常用但非常混乱的词。

　　He is the only person that I can find who is able to solve the problem.
