(十一)动词的语态
1. 语态定义:英语中表示主语和谓语之间的关系的动词形式称为语态。英语的语态分为主动语态和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。We teach English in our school .(主动) English is taught in our school .(被动)
2. 被动语态:助动词Be + 及物动词的过去分词(be +p.p.),be有人称、时态和数的变化。见下表:
时 态 谓语动词的形式 例 子
一般现在时 Am / is / are + 动词过去分词 Colour TVs are made in the factory .
一般过去时 Was / were +动词过去分词 My hometown was liberated in 1949 .
一般将来时 Shall / will + be +动词过去分词 The film will be shown again .
现在进行时 Am / is / are + being +动词过去分词 The walls are being painted .
过去进行时 Was / were +being动词过去分词 The tickets were being well sold then .
现在完成时 Has / have + been + 动词过去分词 A new road has been built here .
时 态 谓语动词的形式 例 子
过去完成时 Had + been +动词过去分词 Much had been done before mother came back .
含有情态动词的被动语态 情态动词+be+动词过去分词 The composition must be handed in today .
3. 被动语态中值得注意的问题:
○1 带有双宾语的动词,可以把任何一个宾语变被动,一般在间接宾语前加适当的介词。My father gave me a book ./ I was given a book by my father ./ A book was given to me by my father .
○2 英语中有些动词用主动语态表示被动语态。The cloth washes well ./ This kind of bags sells well. / The shoes wear long. / The knife cuts well . / The pen writes smoothly . / This coat lasts long .
○3 在英语中有时“be + V-ed”结构并不是被动语态,而是系表结构。The mountains were covered with snow .
○4 在“主语+谓语+宾语+宾语补足语”的结构中,要补留宾语补足语。We found the door broken. / The door was found broken.
○5 宾语补足语为省to的不定式,变为被动语态后,要还原to。He made me laugh. / I was made to laugh .
○6 如果短语动词是及物动词时,可以用被动语态,但不能遗漏所含的介词或副词。The nurse looked after the baby ./ The baby was looked after by the nurse . / We must make up for the lessons we missed. / The lessons we missed must be made up for .
○7 下列情况不能用被动语态:
A. 不及物动词: The accident happened on a busy road yesterday .
B. 连系动词: The girl looks like her sister .
C. 宾语为反身代词:He always dresses himself neatly .
D. 宾语为相互代词:The students often help each other .

Ⅱ 句子
句子的成分
1.定义:组成句子的各个部分叫做句子的成分,即:主语、谓语、表语、宾语、宾语补足语、定语和状语。主语和谓语是句子的主体部分。表语、宾语、宾语补足语都是谓语里的组成部分。
句子成分 意 义 例 句
主 语 表示句子所说的是“什么人”或“什么事物”,一般由名词、代词或相当于名词的词或短语等充当。 Lucy is an American girl .
We study in No.1 Middle School .
谓 语 说明主语“做什么”、“是什么”或者“怎么样”。谓语(谓语部分里主要的词)用动词。谓语和主语在“人称”和“数”两方面必须一致 We love China . / She is singing .

句子的种类
1.英语中按使用目的或功用分为四类:陈述句、疑问句、祈使句、感叹句。
A.陈述句。
○1 陈述句说明一个事实或陈述一个人的看法。陈述句分为肯定陈述句和否定陈述句两种。
a.陈述句的肯定式。I have already posted the photos. / They are students. / I must go now . / He was reading a book at 8:00 last night.
b.陈述句的否定形式。
(1)谓语动词是系动词be, 助动词have, will, shall, be或情态动词,只须在其后面加not构成否定句。
She isn’t a student . / He hasn’t been to the Great Wall . / I can not swim . / You will not go there tomorrow. / They aren’t sleeping .
(2)若谓语动词是实义动词,在实义动词前加上do not,第三人称单数现在时用does not,过去时用did not。
He didn’t send me an invitation .
(3)由具有否定含义的词never, nobody, hardly, little, dislike, seldom, few, too…to等构成的否定句。
Not all the books in our school library can be renewed .
B. 疑问句。
○1 疑问句提出问题。英语中有四种疑问句:一般疑问句、特殊疑问句、选择疑问句和反意疑问句。
a.一般疑问句:以一个助动词、情态动词、动词be或have开始,语调为升调,通常要求以yes或no回答的疑问句。
(1)一般疑问句的基本结构:
Be动词(is, am, are, was, were)+主语+表语…?
Have动词(表示“有”:have, has, had)+主语+宾语…?
情态动词(can, may, must等)+主语+行为动词或be…?
助动词(do, does, did)+主语+行为动词…?
助动词(shall, will, have, has)+主语+行为动词…?
(2)否定形式的疑问句,通常把助动词与not缩写,放在句首。构成回答:
Aren’t you a student? Yes, I am .(不,我是) No, I am not .(对,我不是)
b.特殊疑问句:以疑问代词who, what, whom, whose, which或疑问副词when, where, why, how开头。
(1)如果疑问词在句中作主语或其修饰主语时,其语序如陈述句。Who is on duty today ? / Which book is yours .
(2)如果疑问词在句中不作主语或其修饰主语,用“疑问词+一般疑问句”形式。Where have you been ?
c.选择疑问句:提出两种或两种以上的情况,供回答者选择,并由or连用,但不能用Yes或no 来回答。
(1)疑问句+选择成分1+or+选择成分2?Do you want coffee or cocoa ? / Are you an Englishman or an American ?
(2)特殊问句+选择答案1+or+选择答案2?who runs fast, Tom , Mary or Li lei .
d.反意疑问句:陈述部分+提问部分。
(1)◎前肯后否,前否后肯。 ◎前后人称、数和时态要一致,疑问部分要用代词。◎事实回答用Yes, 非事实回答用No . ◎前陈述句用降调,后问句用升调;如对前陈述句内容有把握,后问句也可用降调。◎如果前面陈述句中有否定词:hardly, little, few, never, rarely, nothing, none , nobody, not, no 等,后面疑问句应该用肯定式。
(2)陈述句中有:have to, had to, ought to, used to, don’t(imperative), somebody / someone, everybody / everyone时,附加疑问句需分别用:don’t, didn’t, shouldn’t, usedn’t / didn’t, will, they等。
My grandma used to be a teacher, usedn’t / didn’t she ? Don’t turn on the TV set, will you ?
(3)陈述句部分是复合句时,提问部分的主语和助动词要与主句一致。He was reading when the teacher came in, wasn’t he ?
(4)在“I think(guess, suppose, believe)+宾语从句”中,当主语是第一人称时,附加疑问句的主语和谓语应与后面宾语从句相一致;但若主语不是第一人称时,则附加问句与前面主句一致。
I don’t think he can pass the exam, can he ? He believed you had seen her before, didn’t he ?
(5)在含有情态动词must 的句子中,若must 表示推测,提问用must后面的动词。若must表示有必要时,用needn’t。若mustn’t表示禁止时,提问用must。
He must be tired, isn’t he ? You must go to Gaozhou, needn’t ? You mustn’t smoke here, must you ?
(6)陈述句部分为祈使句,疑问部分常用will you(表请求)。注:let’s 用shall we(包括说话人),let us 用will you(不包括说话人)。Have a cup of tea, will you ? Let’s go now, shall we ? Let us go now, will you ?
e.祈使句:可表示请求、命令、劝告、建议等。(省主语,动词用原形)

句子类型
1.从结构上看,英语的句子可分为三种类型:简单句、并列句和复合句。
2.简单句:由一个主语(或并列主语)和一个谓语(或并列谓语)构成的句子叫做简单句。简单句有六种句型:
型号 句型 例 子
1 主语+不及物动词(+状语) The Frenchman coughed badly at night. / The city lies in a valley .
2 主语+连系动词+表语 That is a map of China. / That piece of meat looks quite good. / It sounds like the singing of rails .
3 主语+及物动词+宾语 You’re doing the right thing. / Jack likes to stay at home and play by himself .
4 主语+及物动词+间接宾语+直接宾语 Can you tell me the way to the Summer Palace ? / It took me a week to finish the work.

6 There +be+主语+状语 There are some flowers on the teacher’s desk . / There are 365 days in a year .
3.并列句:由并列连词把两个以上的简单句连在一起构成的句子。常用的并列连词有and, but, for, or, nor, so, yet, neither…nor, either…or, still, however, not only…but also等。并列句的结构:简单句+并列词+简单。
Hurry up, or you’ll miss the early bus . / We love peace but we are not afraid of war . / He must be ill, for he is absent today .
She has not only knowledge, but also experience . / He was ill, so he didn’t go to school. / Work hard, and you will succeed .
4.复合句:由一个主句和一个或一个以上的从句构成的句子叫做复合句。主句是句子的主体,从句只用作句子的一个成分,不能独立。从句可以担任复合句的主语(主语从句)、表语(表语从句)、宾语(宾语从句)、定语(定语从句)、状语(状语从句)。中学阶段主要学习含有状语从句、宾语从句、定语从句的复合句。
A.状语从句:在复合句中修饰主句中的动词、形容词或副词等的从句叫做状语从句。状语从句根据它表示的意思的不同可分为时间、地点、原因、结果、让步、比较(或方式)和条件等类。
○1 时间状语从句:由when, while, as, the moment, the minute, once, whenever, before, after, till(until), since, as soon as等连词引导。
主 句 从 句 例 子

○2 条件状语从句:由if, unless, so long as, as long as, in case , if only, provided that等引导。(注:在条件状语从句的将来时态要用现在时和过去时,表示相应的将来时)。
I’ll show you around the city if I am free tomorrow . / If I had enough money, I would buy the car .
○3 原因状语从句:由because(因为), as(由于), since(既然), for(因为)等引导。

○1 宾语从句的连词。
a. 如果宾语从句是从陈述句变化而来的,要用连词that来引导,that可以省略。
b. 如果宾语从句是从一般疑问句变化而来的,要用连词if或whether .
c. 如果宾语从句是从特殊疑问句变化而来的,连词就应该用特殊疑问词(what, when, where…)。
○2 宾语从句的时态:
主 句 从 句 例 子
任何一种时态 一般现在时(表示真理、科学原理、自然现象) The teacher told / tells us that the earth goes round the sun.

○3 宾语从句的人称:人称代词要随合理的逻辑而自然变化。

○4 when 和if 在引导宾语从句和状语从句中,后面的时态有差别。
I don’t know when (何时)she will be back(宾语从句), but when(当…时候) she comes back, I’ll let you know(状语从句) .
I don’t know if(是否) she will come back(宾语从句), but if (如果)she comes back, I’ll let you know (状语从句) .
C.定语从句:在复合句中修饰名词或代词的从句叫做定语从句,被定语从句修饰的名词或代词叫先行词,定语从句必须放在先行词之后。引导从句的关系代词有:who(人,主格), whom(人,宾客), whose(人,所有格), which(物), that(人,物)。引导从句的关系副词有:where(地点), when(时间), why(原因)。
The man who lives next to us is a policeman./ You must do everything that I do ./ We will never forget the day when we visited Gaozhou .

e. 先行词被形容词最高级修饰。 That is the best book that I have read .
f. 先行词被the very, the only, the same修饰。 It is the very book that I am looking for .
g. 先行词是主句的表语或关系代词在定语从句中作表语。 China is no longer the country that it used to be .
h. 先行词是指示代词that, one, those, this, another, all等。 Is this school the one that I saw in the picture ?
i. 主句以who / which开头,定语从句用that 。who is the girl that spoke to you just now ? / which is the car that was made in China ?
○3 只能用which的情况:
a. 关系代词前有介词。 This is the house in which we lived last year .
b. 先行词本身是that 。 The clock is that which I bought yesterday .
c. 非限制性定语从句。 His English , which used to be very poor, is now excellent .
○4 定语从句在句中作定语,所以在使用时,相当于现在分词短语,过去分词短语,动词不定式短语,介词短语作后置定语的句子。
a.I bought a book that was written by Lu Xun . = I bought a book written by Lu Xun .
b.Tell the children who are playing basketball not to do that . = Tell the children playing basketball not to do that .
c.The house that stands at the corner was built in 1987 . = The house standing at the corner was built in 1987 .
d.We have nothing that we should fear . = We have nothing to fear .

○6 在定语从句中,不能再出现指示先行词的指示代词。
I just can’t find the book which/that she lent it to me .(×)---- I just can’t find the book which/that she lent to me .(√)
○7 注意下面的变化:
a. This is the house(不作lived的宾语) where we lived last year .
This is the house(作lived in的宾语) which/that we lived in last year .
b. This is the day (不作left的宾语)when we left for Shenzhen .
This is the day (作spent的宾语)which/that we spent in Shenzhen .
○8 限制性定语从句和非限制性定语从句的区别:
a. 限制性定语从句:是句中不可缺少的组成部分,没有从句,先行词意思不明确,主句也不完整,从句主句不用逗号分开。
b. 非限制性定语从句:是主句先行词的补充说明,没有从句并不影响主句意思的明确或完整,这种定语从句一般用逗号和主句分开,在非限制性定语从句中,一般不用that。
◎ Last Sunday they reached Dalian, where a meeting was to be held .
◎ She has two brothers, who are both doctors .
Ⅲ There be 句型
1. 英语“There + be + (not)”结构表示“有(没有)某人或某物”时,there 是无词义的引导词,be是谓语动词,它后面的名词是主语,两者再数上必须一致。句末往往有表示地点或时间的状语。
2. 肯定句:There +(助动词或情态动词)+be 主语+地点(时间)状语。

5. 特殊疑问句:疑问词(+名词)+be +there + 状语 ?
How many weeks are there in a year ? / What is there on the desk ? / Where will there be a football match tomorrow ?
6. 如果there +be 之后是并列主语,应根据离be 最近的名词来选择be的形式。
There is a apple and two pears on the table . / There are two pears and a apple on the table .
7. 含有引导词there 的句子用seem to be , happen to be , used to be 或live 等作谓语的结构。
There happened to be an old friend of mine in the shop . / There used to be a temple here .
Ⅳ 主谓一致
