A.where B. that C. which D. what 3.Do you still remember the day ___________ I first came to Beijing? A. which B. that C. when D. where A A C

关系副词 when, where 和关系代词 that, which 的区分同样是修饰一个地点，有时使用 where ，有时使用 that/which ；同样是修饰一个时间，有时使用 when ，有时使用 that/which 主要看：从句意思是否完整；完整的话需用关系副词，若意思不完整则需加关系代词充当某个成分。请比较以下句子： This is the park that we visited last year.( 从句意思不完整需要加宾语 ) This is the park where we held a birthday party. （从句完整，只需加上特定的关系副词） That’s the date that she won’t forget for ever. That’s the date when we went to the college. I like the time that we had together. I like the time when we lived together.

限制性定语从句和非限制性定语从句定义：限制性定语从句是先行词不可缺少的修饰成分，否则主句的意思不完整或不成立。非限制性定语从句只对所修饰的词作进一步的说明，去掉之后主句的意思照样完整。 Compare the following sentences: A man who does not try to learn from others can’t achieve much. There’re many plays (that) I’d like to see. This note was left by Xiao Wu, who was just here.

Yesterday Mr Brown paid a visit to Hangzhou, which is famous for its West Lake. They have invited me to visit their country, which is very kind of them. Summarize: 1. 限制性定语从句常和先行词紧密相连；非限制性定语从句与先行词之间常用逗号分开。 2. 非限制性定语从句不能用 that 来引导。 3. 非限制性定语从句有时可以用来修饰整个句子。

一字不改地引用或复述别人的话，被引用或复述的部分就叫直接引语；直接引语必须都放在引号中，其位置常在句尾或句首。用自己的话转述别人的话；被转述的部分就叫间接引语；间接引语不必用括号，一般用宾语从句或复合宾语表达法。

原封不动引用别人的原话, 原话在引号中。 “Take off your boots,” he said. “I don’t know where your bike is,” said the Arab. “I’m sorry,” the professor said to the class, “but none of you watched carefully enough.”

用自己的话转述别人所说的内容。通常以宾语从句的形式出现。当直接引语变为间接引语时，有关的人称、语序、时态、代词、时间状语、地点状语、和少数动词都要作相应的改变。

陈述句：引语前用 that 引导, 有时也可以不用。 He said, “I opened the window this morning.” He said that he opened the window that morning. My sister said, “We have cleaned the floor.” My sister said that they had cleaned the floor.

The manager said to me, “You must go there next week.” The manager told me that I had to go there the next week. The girl said, “I can do my homework myself.” The girl said that she could do her homework herself.

如直接引语是客观真理，变为间接引语时，时态不变。 The teacher said in class, “The moon moves around the earth.” The teacher said in class that the moon moves around the earth.

陈述句直接引语变间接引语的结构： A said that A told B that The girl said that she could do her homework herself. The manager told me that I had to go there the next week.

一般疑问句：变为间接引语后，要用陈述语序（主语先写）用 if 或 whether 引导。时态等作相应变化。 He asked, “Can you hear me?” He asked if/whether I could hear him. The teacher asked, “Have you read this book, Bob?” The teacher asked Bob if/whether he had read that book.

She said to me, “Will you go there with me?” She asked me if/whether I would go there with her. She asked, “Did you see the film yesterday, Peter?” She asked Peter if/whether he had seen the film the day before. “Are you leaving today or tomorrow?” Joan asked Kate.

祈使句：改为间接引语后，就成了以不定式短语形式出现的宾语补足语（动词常是 ask/ tell/order/advise/warn /remind 等）。 He said to the girl, “Do it at once.” He told the girl to do it at once. Mrs. Hill said, “ please sing at our party, Mary.” Mrs. Hill asked Mary to sing at their party.

She said to me, “Don’t smoke in the classroom.” She told me not to smoke in the classroom. He said, “Let’s go fishing tomorrow.” He suggested going fishing the next day.

由直接引语转变为间接引语, 有时会引时态的变化, 注意以下几个方面由直接引语转变为间接引语, 有时会引时态的变化, 注意以下几个方面 1. 主句动词为一般现在时、现在完成时或一般将来时，在转述直接引语过程中可以不作任何时态改变：直接引语 She often says, “All men and women are equal under the law.” 间接引语 She often says that all men and women are equal under the law.

由直接引语转变为间接引语, 下列情况时态不变 1. 不变的真理： The teacher said to the students, “ Water freezes when the temperature falls below 0 ℃. ” → The teacher told the students that water freezes when the temperature falls below 0 ℃. 2. 经常的习惯 ( ) 2. 经常的习惯 ( 强调动作或状态现在仍然如此时， ) He said to the doctor, “ I smoke two packs every day. ” He said to the doctor, “ I smoke two packs every day. ” → He told the doctor that he smokes two packs every day. → He told the doctor that he smokes two packs every day.

3. 历史事件 ( 3. 历史事件 ( 直接引语中有绝对具体的过去时间做状语时 ) The teacher said, “ World War Ⅱ ended in 1945. ” The teacher said, “ World War Ⅱ ended in 1945. ” → The teacher said that World War Ⅱ ended in 1945. → The teacher said that World War Ⅱ ended in 1945. 4. 部分情态动词, 如 must, ought to, used to, had better 等： She said to me: “ You must hurry up. ” She said to me: “ You must hurry up. ” → She said that I must hurry up.

一般将来时的被动语态用法例析一般将来时的被动语态是被动语态学习中的难点, 也是重点。本文通过对若干典型例题的分析, 对其进行了归纳和总结, 希望对同学们有所帮助。 1. 基本结构一 : shall/will + be + done 【经典例题 1 】 I promise that this matter _____ next week. A. will be taken care B. will take care of C. will take good care D. will be taken care of 【思路点拨】选 D 。从题干不难看出, 一是从句中的 this matter 和 take care of 是被动关系 ; 二是 take care of 是固定搭配, 不能拆开 ; 三是相对于 promise 来说,take care of 是将要发生的动作。故从句谓语应用一般将来时的被动语态。

【经典例题 2 】 These dictionaries _____ the library again (by you ). A. will be taken out ofB. won’t be taken out of C. will take out of D. won’t take out of 【思路点拨】选 B 。由题干结构及句意可知, 此题考查的是一般将来时的被动语态的否定式。另外, 我们还应注意 : 其疑问式为 Shall/Will + 主语 + be + done...? 或特殊疑问词 + shall/will + 主语 + be + done...?

2. 基本结构二 : be(am / is /are)going to + be + done 【经典例题 1 】 The class ____ on everything they have learnt this year. A. is going to be examining B. are going to examine C. is going to be examined D. are going to be examined 【思路点拨】选 D 。题中 the class 指全班同学, 谓语动词应用复数形式, 并且主语和谓语动词之间是被动关系, 所以谓语应用一般将来时的被动语态。

【经典例题 2 】 An exhibition of painting _____ at the art museum when he comes back from abroad. A. is going to hold B. is going to be held C. are going to hold D. are going to be held 【思路点拨】选 B 。根据题意, 此处应用一般将来时的被动语态, 而且主谓应保持一致。

现在进行时的被动语态 “ 四注意 ” 一. 注意不可遗漏 being 现在进行时的被动语态表示说话时正在进行的一个被动的动作, 强调主语是动作的承受者, 其构成为 “ am / is / are + being+ 动词的过去分词 ” 。如果我们把 being 漏掉, 就成为一般现在时的被动语态或系表结构。如 : * Look! The children are being taken care of by their aunt. 瞧 ! 那些孩子正由他们的姑妈照看着。 * Children are taken good care of at school. 孩子们在学校被照看得很好。 ( 指通常情况 ) * The report is being written by one of the best students. 报告正在由一名最好的学生写着呢。 * The report is well written. 这个报告写得很好。 ( 系表结构 )

二. 注意现在进行时的被动语态也可以表示将来现在进行时的被动语态有时可表示按计划或安排将要进行的一个被动的动作 ( 此种用法仅限于少数及物动词 ) 。如 : A party is being held tonight. 今晚将要举行一场晚会。

三. 注意没有现在进行时的被动语态的动词一些表示 “ 状态、心理活动、拥有、存在 ” 等的动词, 一般不用现在进行时的被动语态, 而常用一般现在时的被动语态。如 : Xiao Wang, come here. You are wanted on the phone. 小王, 过来, 有你的电话。 Football is becoming more and more popular. In other words, it is loved by more and more people. 足球现在越来越流行了, 换句话说, 它被越来越多的人喜爱。

. 四. 注意 “be +under/ in 等介词 + 名词 ” 结构可表示现在进行时的被动语态的含义。如 : The problem is under discussion (is being discussed) at the meeting. 这个问题正在会上讨论。 The telephone is in use (=is being used) now. 这部电话正在使用中。

现在完成时的被动语态一二三一、现在完成时的被动语态的用法 1. 表示一个被动的动作发生在说话之前, 强调对现在造成的影响和结果。如 : The door has been locked. 门被锁上了。 2. 表示一个被动的动作或状态开始于过去, 持续到现在, 并可能持续下去, 常与 for 或 since 引导的时间状语连用, 或用于 How long...? 句型中。如 : The important problem has been discussed for nearly two weeks. 那个重要的问题已经被讨论近两个星期了。 How long has the machine been used? 这机器使用有多久了 ?

二、现在完成时的被动语态应注意的几个问题 1. 请注意现在完成时的被动语态的两个助动词, 即 have/has 和 been, 两者缺一不可。 2. 请注意与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系, 而现在完成时的被动语态则强调与现在情况的联系。如 : The bridge was built last year. 这桥是去年建成的。 The bridge has been built. 这桥已经建好了。

3. 请注意一些特殊动词, 如 borrow, finish, begin, buy, start, return, marry, open, join 等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思, 则需改换动词或时态。如 : [ 误 ] How long has this book been bought? [ 正 ] How long ago was this book bought? 但这类动词的否定式可表示动作的持续过程, 具有连续性, 因而可与 since 或 for 引导的时间状语连用。如 : No books have been bought since last week. 自上周以来, 没有人来买过书。
