He is taller than I am. 2) 主格代替宾格 a. 在介词but,except 后,有时可用主格代替宾格。 b. 在电话用语中常用主格。 ---- I wish to speak to Mary. --我想和玛丽通话。 ---- This is she. --我就是玛丽。 注意:在动词be 或to be 后的人称代词视其前面的名词或代词而定。 I thought it was she. 我以为是她。 (主格----主格) I thought it to be her. (宾格----宾格) I was taken to be she. 我被当成了她。 (主格----主格) They took me to be her. 他们把我当成了她。 (宾格----宾格) 3.3 代词的指代问题 1)不定代词 anybody,everybody,nobody,anyone, someone, everyone,no one, 及whoever和person在正式场合使用时,可用he, his, him代替。 Nobody came, did he? 谁也没来,是吗? 2)动物名词的指代一般用it或they代替,有时也用he, she,带有亲切的感情色彩。 Give the cat some food. She is hungry. 给这猫一些吃的。她饿了。 3)指代车或国家,船舶的名词,含感情色彩时常用she。 3.4 并列人称代词的排列顺序 1) 单数人称代词并列作主语时,其顺序为: 第二人称 -> 第三人称 -> 第一人称 you -> he/she; it -> I You, he and I should return on time. 2) 复数人称代词作主语时,其顺序为: 第一人称 -> 第二人称 -> 第三人称 we -> you -> They 注意: 在下列情况中,第一人称放在前面。 a. 在承认错误,承担责任时, It was I and John that made her angry. 是我和约翰惹她生气了。 b. 在长辈对晚辈,长官对下属说话时,如长官为第一人称, 如:I and you try to finish it. c. 并列主语只有第一人称和第三人称时, d. 当其他人称代词或名词被定语从句修饰时。 3.5 物主代词 1)物主代词既有表示所属的作用又有指代作用,例如: John had cut his finger; apparently there was a broken glass on his desk. 约翰割破了手指,显而易见,他桌子上有个破玻璃杯。 物主代词有形容词性(my, your等)和名词性(mine, yours等)两种,形容词性的物主代词属于限定词。 名词性的物主代词在用法上相当于省略了中心名词的 --'s属格结构,例如: Jack's cap 意为 The cap is Jack's. His cap 意为 The cap is his. 2) 名词性物主代词的句法功能 a. 作主语,例如: May I use your pen? Yours works better. 我可以用一用你的钢笔吗? 你的比我的好用。 b. 作宾语,例如: I love my motherland as much as you love yours. 我爱我的祖国就像你爱你的祖国一样深。 c. 作介词宾语,例如: Your should interpret what I said in my sense of the word, not in yours. 你应当按我所用的词义去解释我说的话,而不能按你自己的意义去解释。 d. 作主语补语,例如: The life I have is yours. It's yours. It's yours. 我的生命属于你,属于你,属于你。 3.6 双重所有格 物主代词不可与 a, an, this, that, these, those, some, any, several, no, each, every, such, another, which等词一起前置,修饰一个名词,而必须用双重所有格。 公式为: a, an, this, that +名词+of +名词性物主代词。如: a friend of mine. each brother of his 3.7 反身代词 1) 列表 I you you she he myself yourself yourselves herself himself we they it one ourselves themselves itself oneself 2)做宾语 a. 有些动词需有反身代词 absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave We enjoyed ourselves very much last night. 我们昨晚玩得很开心。 Please help yourself to some fish. 请你随便吃点鱼。 b. 用于及物动词+宾语+介词 take pride in, be annoyed with, help oneself to sth.

(对) I myself drove the car. 我自己开车。 b. 但在and, or, nor连接的并列主语中,第二个主语可用反身代词,特别是myself 作主语。 Charles and myself saw it. 5)第二人称作宾语,要用反身代词。 You should be proud of yourself. 你应为自己感到骄傲。 3.8 相互代词 1)相互代词只有each other和one another两个词组。他们表示句中动词所叙述的动作或感觉在涉及的各个对象之间是相互存在的,例如: It is easy to see that the people of different cultures have always copied each other. 显而易见,不同文化的人总是相互借鉴的。 2) 相互代词的句法功能: a. 作动词宾语; People should love one another. 人们应当彼此相爱。 b. 可作介词宾语; Does bark, cocks crow, frogs croak to each other. 吠、鸡鸣、蛙儿对唱。 说明:传统语法认为,相互关系存在于两个人或物之间用each other, 存在于两个以上人和物之间用one another。现代英语中,两组词交替使用的实例也很多,例如: He put all the books beside each other. 他把所有书并列摆放起来。 He put all the books beside one another. 他把所有书并列摆放起来。 Usually these small groups were independent of each other. 这些小团体通常是相互独立的。 c. 相互代词可加-'s构成所有格,例如: The students borrowed each other's notes. 学生们互借笔记。 3.9 指示代词 1) 指示代词分单数(this / that)和复数(these / those)两种形式,既可作限定词又可做代词,例如: 单数 复数 限定词:This girl is Mary. Those men are my teachers. 代词: This is Mary. Those are my teachers. 2) 指示代词的句法功能; a. 作主语 This is the way to do it. 这事儿就该这样做。 b. 作宾语 I like this better than that. 我喜欢这个甚至那个。 c. 作主语补语 My point is this. 我的观点就是如此。 d. 作介词宾语 I don't say no to that. 我并未拒绝那个。 There is no fear of that. 那并不可怕。 说明1: 指示代词在作主语时可指物也可指人,但作其他句子成分时只能指物,不能指人,例如: (对)That is my teacher. 那是我的老师。( that作主语,指人) (对)He is going to marry this girl. 他要和这个姑娘结婚。(this作限定词) (错)He is going to marry this. (this作宾语时不能指人) (对)I bought this. 我买这个。(this指物,可作宾语) 说明2: That和those可作定语从句的先行词,但this和 these不能,同时,在作先行词时,只有those可指人,试比较: (对) He admired that which looked beautiful. 他赞赏外表漂亮的东西。 (对) He admired those who looked beautiful. 他赞赏那些外表漂亮的人。(those指人) (错) He admired that who danced well. (that作宾语时不能指人) (对) He admired those who danced well. 他赞赏跳舞好的人。(those指人) (对) He admired those which looked beautiful. 他赞赏那些外表漂亮的东西。(those指物) 3.10 疑问代词 1) 疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个: 指 人: who, whom, whose 指 物: what 既可指人又可指物: which 2) 疑问代词在句中应位于谓语动词之前,没有性和数的变化,除who之外也没有格的变化。what, which, whose还可作限定词。试比较: 疑问代词:Whose are these books on the desk? 桌上的书是谁的? What was the directional flow of U. S. territorial expansion? 美国的领土扩张是朝哪个方向的? 限定词: Whose books are these on the desk? 桌上的书是谁的? What events led to most of the east of the Mississippi River becoming part of the United States? 哪些事件使密西西比河以东的大部分土地归属于美国? 说明1: 无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如: Which girls do you like best? 你喜欢哪几个姑娘? What girls do you like best? 你喜欢什么样的姑娘? 说明2: Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如: Who(m) did you meet on the street? 你在街上遇到了谁?(作动词宾语) Who(m) are you taking the book to? 你要把这书带给谁?(作介词宾语,置句首) To whom did you speak on the campus? 你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。) 说明3: 疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如: For what do most people live and work? 大部分人生活和工作的目的是什么?(旧文体) What are you looking for? 你在找什么?(现代英语) 说明4: 疑问代词还可引导名词性从句,例如: I can't make out what he is driving at. 我不知道他用意何在。 Can you tell me whose is the blue shirt on the bed? 你能告诉我床上的蓝衬衣是谁的吗? Much of what you say I agree with, but I cannot go all the way with you. 你说的我大部分同意,但并不完全赞同。 3.11 关系代词 1) 关系代词用来引导定语从句。它代表先行词,同时在从句中作一定的句子成分,例如:The girl to whom I spoke is my cousin. 跟我讲话的姑娘是我表妹。(该句中whom既代表先行词the girl,又在从句中作介词to的宾语。) 2) 关系代词有主格,宾格和属格之分,并有指人与指物之分。在限定性定语从句中,that 可指人也可指物,见表: 限定性 非限定性 限定性 指 人 指 物 指人或指物 主 格 who which that 宾 格 whom that that 属 格 whose of which/whose of which/whose 例如: This is the pencil whose point is broken. 这就是那个折了尖的铅笔。 (whose 指物,在限定性定语从句中作定语) He came back for the book which he had forgotten. 他回来取他丢下的书。 (which指物,在限定性定语从句中作宾语,可以省略) 3) 关系代词which的先行词可以是一个句子,例如: He said he saw me there, which was a lie. 他说在那儿看到了我,纯属谎言。 说明: 关系代词that在从句中作宾语或表语时可省略, 例如: I've forgotten much of the Latin I once knew. 我过去懂拉丁语,现在大都忘了。 He's changed.

Yes,I 've bought some. 3.14 代词比较辩异 one,that 和it one表示泛指,that和it 表示特指。that与所指名词为同类,但不是同一个,而it 与所指名词为同一个。 I can't find my hat. I think I must buy one. (不定) 我找不到我的帽子了。我想我该去买一顶。 The hat you bought is bigger than that I bought. (同类但不同个) 你买的那顶帽子比我买的大。 I can't find my hat. I don' t know where I put it.

(两岸) There are flowers on either side of the street. (岸的两边) 路边长满了野花。 3) all (所有的,全部的人或物),any (任何一个), none (都不)。 以上词使用范围为三者以上。 All the flowers are gone. 所有的花都谢了。 I don't like any of the flowers. 这些花我都不喜欢。 I like none of the flowers. 这些花我都不喜欢。 注意:all与none用法一样。跟单数名词,用单数动词;跟复数名词,用复数动词。 All of the students are there. 所有的学生都在那。 All (of) the milk is there. 所有的牛奶都在那。 3.19 many, much Many,much都意为"许多", many + 可数名词,much + 不可数名词。 How many people are there at the meeting? How much time has we left? Many of the workers were at the meeting. Much of the time was spent on learning. 3.20 few, little, a few, a little (a) few + 可数名词, (a) little + 不可数名词 a few / a little 为肯定含义,还有一点 few / little 为否定含义,没有多少了。 He has a few friends. 他有几个朋友。 He has few friends. 他几乎没有朋友。 We still have a little time. 我们还有点时间。 There is little time left.几乎没剩下什么时间了。 典型例题: Although he 's wealthy,he spends___ on clothes. A. little B. few C. a little D. a few 答案: A. spend所指的是钱,不可数,只能用little或 a little. 本句为although引导的让步状语从句,由句意知后句为否定含义,因此应用little表示几乎不。 固定搭配: only a few (=few) not a few (=many) quite a few (=many) many a (=many) Many books were sold. Many a book was sold. 卖出了许多书。 形容词和副词 4.1 形容词及其用法 形容词修饰名词,说明事物或人的性质或特征。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。 1) 直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot 热的。 2) 叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid 害怕的。 (错) He is an ill man. (对) The man is ill. (错) She is an afraid girl. (对) The girl is afraid. 这类词还有: well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake 等。 3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后,例如: something nice 4.2 以-ly结尾的形容词 1) 大部分形容词加-ly可构成副词。但 friendly,deadly,lovely,lonely,likely,lively, ugly,brotherly,仍为形容词。 改错:(错) She sang lovely. (错) He spoke to me very friendly. (对) Her singing was lovely. (对) He spoke to me in a very friendly way. 2)有些以-ly 结尾既为形容词,也为副词。 daily,weekly,monthly,yearly,early The Times is a daily paper. The Times is published daily. 4.3 用形容词表示类别和整体 1) 某些形容词加上定冠词可以泛指一类人,与谓语动词的复数连接。如:the dead,the living,the rich,the poor,the blind,the hungry The poor are losing hope. 2) 有关国家和民族的形容词加上定冠词指这个民族的整体,与动词的复数连用。 the British,the English,the French,the Chinese. The English have wonderful sense of humor. 4.4 多个形容词修饰名词的顺序 多个形容词修饰名词时,其顺序为: 限定词--数词--描绘词--(大小,长短,形状,新旧,颜色) --出处--材料性质,类别--名词 a small round table a tall gray building a dirty old brown shirt a famous German medical school an expensive Japanese sports car 典型例题: 1) Tony is going camping with ___ boys. A. little two other B. two little other C. two other little D. little other two 答案:C。由"限定词--数词--描绘词--(大小,长短,形状,新旧,颜色) --性质--名词"的公式可知数词,描绘词,性质依次顺序,只有C符合答案。 2) One day they crossed the ____bridge behind the palace. A. old Chinese stone B. Chinese old stone C. old stone Chinese D. Chinese stone old 答案A. 几个形容词修饰一个名词,他们的排列顺序是:年龄,形状,大小+颜色+来源+质地+用途+国家+名词。 3) ---- How was your recent visit to Qingdao? ---- It was great. We visited some friends,and spent the ___days at the seaside. A. few last sunny B. last few sunny C. last sunny few D. few sunny last 答案:B。本题考查多个形容词的排序问题。一般与被修饰形容词关系密切的形容词靠近名词;如果几个形容词的重要性差不多,音节少的形容词在前,音节多的方在后,在不能确定时,可参照下表: 限定词+数量词(序数词在前,基数词在后)+性状形容词+大小、长短、高低等形体+ those + three + beautiful + large + square 新旧+颜色+国籍+材料+名词 old + brown + wood + table 4.5 副词及其基本用法 副词主要用来修饰动词,形容词,副词或其他结构。 一、副词的位置: 1) 在动词之前。 2) 在be动词、助动词之后。 3) 多个助动词时,副词一般放在第一个助动词后。 注意: a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡。 We could see very clearly a strange light ahead of us. b. 方式副词well,badly糟、坏,hard等只放在句尾。 He speaks English well. 二、副词的排列顺序: 1) 时间,地点副词,小单位的在前,大单位在后。 2) 方式副词,短的在前,长的在后,并用and或but等连词连接。 Please write slowly and carefully. 3) 多个不同副词排列:程度+地点+方式+时间副词。 注意:副词very 可以修饰形容词,但不能修饰动词。 改错:(错) I very like English. (对) I like English very much. 注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可。 I don't know him well enough. There is enough food for everyone to eat. There is food enough for everyone to eat. 4.6 兼有两种形式的副词 1) close与closely close意思是"近"; closely 意思是"仔细地" He is sitting close to me. Watch him closely. 2) late 与lately late意思是"晚"; lately 意思是"最近" You have come too late. What have you been doing lately? 3) deep与deeply deep意思是"深",表示空间深度;deeply时常表示感情上的深度,"深深地" He pushed the stick deep into the mud. Even father was deeply moved by the film. 4) high与highly high表示空间高度;highly表示程度,相当于much The plane was flying high. I think highly of your opinion. 5) wide与widely wide表示空间宽度;widely意思是"广泛地","在许多地方" He opened the door wide. English is widely used in the world. 6) free与freely free的意思是"免费";freely 的意思是"无限制地" You can eat free in my restaurant whenever you like. You may speak freely; say what you like. 4.7 形容词与副词的比较级 大多数形容词(性质形容词)和副词有比较级和最高级的变化,即原级、比较级和最高级,用来表示事物的等级差别。原级即形容词的原形,比较级和最高级有规则变化和不规则变化两种。 1) 规则变化 单音节词和少数双音节词,加词尾-er,-est来构成比较级和最高级。 构成法 原级 比较级 最高级 一般单音节词 tall(高的) taller tallest 未尾加-er,-est great(巨大的) greater greatest 以不发音的e结尾 nice(好的) nicer nicest 的单音词和少数 large(大的) larger largest 以- le结尾的双 able(有能力的) abler ablest 音节词只加-r,-st 以一个辅音字母 big(大的) bigger biggest 结尾的闭音节单 hot热的) hotter hottest 音节词,双写结 尾的辅音字母, 再加-er,-est "以辅音字母+y" easy(容易的) easier easiest 结尾的双音节词,busy(忙的) busier busiest 改y为i,再加 -er,-est 少数以-er,-ow clever(聪明的) cleverer cleverest 结尾的双音节词 narrow(窄的) narrower narrowest 未尾加-er,-est 其他双音节词和 important(重要的) 多音节词,在前 more important 面加more,most most important 来构成比较级和 easily(容易地) 最高级。 more easily most easily 2) 不规则变化 原级 比较级 最高级 good(好的)/ better best well(健康的) bad (坏的)/ worse worst ill(有病的) old (老的) older/elder oldest/eldest much/many(多的) more most little(少的) less least far (远的) farther/further farthest/furthest 4.8 as + 形容词或副词原级 + as 1)在否定句或疑问句中可用so… as。 He cannot run so/as fast as you. 2)当as… as 中间有名词时采用以下格式。 as +形容词+ a +单数名词 as + many/much +名词 This is as good an example as the other is. I can carry as much paper as you can.. 3)用表示倍数的词或其他程度副词做修饰语时,放在as的前面。 This room is twice as big as that one. Your room is the same size as mine. 4) 倍数+ as + adj. + as <=> 倍数+ then + of This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine. 4.9 比较级形容词或副词 + than You are taller than I. They lights in your room are as bright as those in mine. 注意: 1)要避免重复使用比较级。 (错) He is more cleverer than his brother. (对) He is more clever than his brother. (对) He is clever than his brother. 2)要避免将主语含在比较对象中。 (错) China is larger that any country in Asia. (对) China is larger than any other countries in Asia. 3)要注意对应句型,遵循前后一致的原则。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out. 4)要注意冠词的使用,后有名词的时候,前面才有可能有名词。 比较:Which is large, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters. 4.10 可修饰比较级的词 1)a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等 2)还可以用表示倍数的词或度量名词作修饰语。 3)以上词(除by far)外,必须置于比较级形容词或副词的前面。 典型例题: 1) ---- Are you feeling ____? ---- Yes,I'm fine now. A. any well B. any better C. quite good D. quite better 答案:B. any 可修饰比较级,quite修饰原级,well的比较级为better. 2)The experiment was____ easier than we had expected. A. more B. much more C. much D. more much 答案:C. much可修饰比较级,因此B,C都说得通,但easier本身已是比较级,不需more,因此C为正确答案。 3)If there were no examinations, we should have ___ at school. A. the happiest time B. a more happier time C. much happiest time D. a much happier time 答案:D。 4.11 many,old 和 far 1) 如果后接名词时, much more +不可数名词 many more +可数名词复数 2) old 有两种比较级和最高级形式: older/oldest 和elder/eldest。 elder,eldest 只用于兄弟姐妹的长幼关系。 My elder brother is an engineer. Mary is the eldest of the three sisters. 3) far 有两种比较级,farther,further. 在英语中两者都可指距离。 在美语中,father 表示距离,further表示进一步。 I have nothing further to say. 4.12 the + 最高级 + 比较范围 1) The Sahara is the biggest desert in the world. 形容词最高级前通常必须用定冠词 the,副词最高级前可不用。 形容词most前面没有the,不表示最高级的含义,只表示"非常"。 It is a most important problem. =It is a very important problem. 注意: 使用最高级要注意将主语包括在比较范围内。 (错) Tom is the tallest of his three brothers. (对) Tom is the tallest of the three brothers. 2) 下列词可修饰最高级,by far, far, much, mostly, almost This hat is nearly / almost the biggest. 注意: a. very可修饰最高级,但位置与much不同。 This is the very best. This is much the best. b. 序数词通常只修饰最高级。 Africa is the second largest continent. 3) 句型转换: Mike is the most intelligent in his class. Mike is more intelligent than any other students in his class. 4) "否定词语+比较级","否定词语+ so… as"结构表示最高级含义。 Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing. 4.13 和more有关的词组 1) the more… the more… 越……就越…… The harder you work,the greater progress you'll make. 2) more B than A 与其说A不如说B less A than B He is more lazy than slow at his work. = He is less slow than lazy at his work. 3) no more… than… 与……一样……,不比……多 The officials could see no more than the Emperor. no less… than… 与……一样…… He is no less diligent than you. 4) more than 不只是,非常 She is more than kind to us all. 典型例题 1)The weather in China is different from____. A. in America B. one in America C. America D. that in America 答案:D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家,C不能选。A没有名词,后句成分不全,排除。B和D中,B中的one常用来代替可数名词,而that可车以代替不可数或抽象名词,所以选D。 2)After the new technique was introduced,the factory produced ___ tractors in 1988 as the year before. A. as twice many B. as many twice C. twice as many D. twice many as 答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。 表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。 This ruler is three times as long as that one. 动词 5.1 系动词 系动词亦称联系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。 说明: 有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语,例如: He fell ill yesterday. 他昨天病了。(fell是系动词,后跟补足语,说明主语情况。) He fell off the ladder. 他从梯子上摔下来。fell是实义动词,单独作谓语。 1)状态系动词 用来表示主语状态,只有be一词,例如: He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。) 2)持续系动词 用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如: He always kept silent at meeting. 他开会时总保持沉默。 This matter rests a mystery. 此事仍是一个谜。 3)表像系动词 用来表示"看起来像"这一概念,主要有seem, appear, look, 例如: He looks tired. 他看起来很累。 He seems (to be) very sad. 他看起来很伤心。 4)感官系动词 感官系动词主要有feel, smell, sound, taste, 例如: This kind of cloth feels very soft. 这种布手感很软。 This flower smells very sweet. 这朵花闻起来很香。 5)变化系动词 这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run. 例如: He became mad after that. 自那之后,他疯了。 She grew rich within a short time. 她没多长时间就富了。 6)终止系动词 表示主语已终止动作,主要有prove, trun out, 表达"证实","变成"之意,例如: The rumor proved false. 这谣言证实有假。 The search proved difficult. 搜查证实很难。 His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果) 5.2 什么是助动词 1)协助主要动词构成谓语动词词组的词叫助动词(Auxiliary Verb)。被协助的动词称作主要动词(Main Verb)。 助动词自身没有词义,不可单独使用,例如: He doesn't like English. 他不喜欢英语。 (doesn't是助动词,无词义;like是主要动词,有词义) 2) 助动词协助主要动词完成以下功用,可以用来: a. 表示时态,例如: He is singing. 他在唱歌。 He has got married. 他已结婚。 b. 表示语态,例如: He was sent to England. 他被派往英国。 c. 构成疑问句,例如: Do you like college life? 你喜欢大学生活吗?

He knows how to drive a car, doesn't he? 他知道如何开车,对吧? 5.6 助动词shall和will的用法 shall和will作为助动词可以与动词原形一起构成一般将来时,例如: I shall study harder at English. 我将更加努力地学习英语。 He will go to Shanghai. 他要去上海。 说明: 在过去的语法中,语法学家说shall用于第一人称,will 只用于第二、第三人称。现在,尤其是在口语中,will常用于第一人称,但shall只用于第一人称,如用于第二、第三人称,就失去助动词的意义,已变为情态动词,试比较: He shall come. 他必须来。(shall有命令的意味。) He will come. 他要来。(will只与动词原形构成一般将来时。) 5.7 助动词should,would的用法 1)should无词义,只是shall的过去形式,与动词原形构成过去将来时,只用于第一人称,例如: I telephoned him yesterday to ask what I should do next week. 我昨天给他打电话,问他我下周干什么。 比较: "What shall I do next week?" I asked. "我下周干什么?"我问道。(可以说,shall变成间接引语时,变成了should。) 2) would也无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如: He said he would come. 他说他要来。 比较: "I will go," he said. 他说:"我要去那儿。" 变成间接引语,就成了: He said he would come. 原来的will变成would,go变成了come.。 5.8 短语动词 动词加小品构成的起动词作用的短语叫短语动词(Phrasal Verb)。例如: Turn off the radio. 把收音机关上。(turn off是短语动词) 短语动词的构成基本有下列几种: 1) 动词+副词,如:black out; 2) 动词+介词,如:look into; 3) 动词+副词+介词,如:look forward to。构成短语动词的副词和介词都统称为小品词(Particle)。 5.9 非谓语动词 在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。 1)不定式 时态\语态 主动 被动 一般式 to do to be done 完成式 to have done to have been done 2)动名词 时态\语态 主动 被动 一般式 doing being done 完成式 having done having been done 3)分词 时态\语态 主动 被动 一般式 doing being done 完成式 having done having been done 否定形式: not +不定式, not + 动名词, not + 现在分词 动名词 6.1 动名词作主语、宾语和表语 1)作主语 Fighting broke out between the South and the North. 南方与北方开战了。 2)作宾语 a. 动词后加动名词doing作宾语 V. + doing sth admit 承认 appreciate 感激,赞赏 avoid 避免 complete 完成 consider 认为 delay 耽误 deny 否认 detest 讨厌 endure 忍受 enjoy 喜欢 escape 逃脱 prevent阻止 fancy 想象 finish 完成 imagine 想象 mind 介意 miss 想念 postpone 推迟 practise 训练 recall 回忆 resent 讨厌 resist 抵抗 resume 继续 risk 冒险 suggest 建议 face 面对 include 包括 stand 忍受 understand 理解 forgive 宽恕 keep 继续 举例: (1) Would you mind turning down your radio a little, please? (2) The squirrel was lucky that it just missed being caught. b. 词组后接doing admit to prefer…to be used to lead to devote oneself to object to stick to be busy look forward to to为介词) no good, no use, It's worth…, as well as, can't help, It's no use /good be tired of be fond of be capable of be afraid of be proud of think of / about hold off put off keep on insist on count on / upon set about be successful in good at take up give up burst out prevent … from… 3)作表语 Her job is washing,cleaning and taking care of the children. 6.2 worth 的用法 worth,worthy,worth-while都为adj. 意为"值得"。 1. worth: be worth + n. 当名词为金钱时,表示"…… 值得……" be worth doing sth. "……某事值得被做" The question is not worth discussing again and again. 2. worthy:be worthy of +n. 当名词为抽象名词时表示"……值得……" be worthy to be done "某事值得被做" The question is not worthy to be discussed againand again. 3. worth-while: be worth-while to do sth "值得做某事" worth while: It is worth while doing sth It is worth while sb to do sth. 典型例题 It is not ____ to discuss the question again and again. A.worth B.worthy C.worth-while D.worth while 答案C. 由worth的用法可知,此句只适合词组be worth-while to do sth.。因此选C。 动词不定式 7.1 不定式作宾语 1) 动词+ 不定式 afford aim appear agree arrange ask be decide bother care choose come dare demand desire determine expect elect endeavor hope fail happen help hesitate learn long mean manage offer ought plan prepare pretend promise refuse seem tend wait wish undertake 举例: The driver failed to see the other car in time. 司机没能及时看见另一辆车。 I happen to know the answer to your question. 我碰巧知道你那道问题的答案。 2)动词+不定式 ; 动词+宾语+不定式 ask, beg, choose, expect , hate, help intend like, love, need prefer, prepare, promise, want, wish… I like to keep everything tidy. 我喜欢每件东西都保持整洁。 I like you to keep everything tidy. 我喜欢你年使每件东西都保持整洁。 I want to speak to Tom. 我想和汤姆谈话。 I want you to speak to Tom. 我想让你和汤姆谈话。 3) 动词+疑问词+ to decide, know, consider forget, learn, remember, show, understand, see, wonder, hear, find out, explain, tell Please show us how to do that. 请演示给我们如何去做。 There are so many kinds of tape-recorders on sale that I can't make up my mind which to buy.有这么多的录音机,我都拿不定主意买哪一种。 注意:疑问词带不定式在句中作成分时,谓语动词用单数。 The question is how to put it into practice. 问题是怎样把它付诸实施。 7.2 不定式作补语 1) 动词+宾语+不定式(to do) advise allow appoint believe cause challenge command compel consider declare drive enable encourage find forbid force guess hire imagine impel induce inform instruct invite judge know like order permit persuade remind report request require select send state suppose tell think train trust understand urge warn 例句: a. Father will not allow us to play on the street. 父亲不让我们在街上玩耍。 b. We believe him to be guilty. 我们相信他是有罪的。 Find 的特殊用法: Find 后可用分词做宾补,或先加形式宾语,再加形容词,最后加带to 的动词不定式。find后也可带一个从句。此类动词还有get,have。 I found him lying on the ground. I found it important to learn. I found that to learn English is important. 典型例题: The next morning she found the man ___ in bed,dead. A. lying B. lie C. lay D. laying 答案:A.find的宾语后面,用分词或分词短语,起宾语补足语作用。现在分词表达主动,也表达正在进行,过去分词表达被动。 2) to + be 的不定式结构,作补语的动词。 Acknowledge, believe, consider, think, declare(声称), discover, fancy(设想), feel find, guess, judge, imagine, know, prove, see(理解), show, suppose, take(以为), understand We consider Tom to be one of the best students in our class. 我们认为汤姆是班上最好的学生之一。 典型例题 Charles Babbage is generally considered ___ the first computer. A. to invent B. inventing C. to have invented D. having invented 答案:A. 由consider to do sth. 排除B、D。. 此句只说明发明这一个事实,不定式后用原形即可。而C为现在完成时,发明为点动词一般不用完成时,且此处也不强调对现在的影响,因此不选C。 3) to be +形容词 Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean… The book is believed to be uninteresting. 人们认为这本书没什么意思。 4) there be+不定式 believe, expect, intend, like, love, mean, prefer, want, wish, undrstand We didn't expect there to be so many people there.我们没料到会有那么多人在哪里。 注意 : 有些动词需用as 短语做补语,如regard, think believe, take, consider. We regard Tom as our best teacher. 我们认为汤姆是我们最好的老师。 Mary took him as her father . 玛丽把他当作自己的父亲。 7.3 不定式主语 1) It's easy (for me) to do that.我做这事太容易了 easy, difficult, hard, important, possible, impossible, comfortable, necessary, better; the first, the next, the last, the best, too much, too little, not enough It's so nice to hear your voice. 听到你的声音真高兴。 It's necessary for you to lock the car when you do not use it. 当你不用车的时候,锁车是有必要的。 2) It's very kind of you to help us. 他帮助我们,他真好。 Kind, nice, stupid, rude, clever, foolish, thoughtful, thoughtless, brave, considerate(考虑周到的), silly, selfish(自私的) 例句: It was silly of us to believe him. 我们真愚蠢,竟然相信了他。 It seemed selfish of him not to give them anything. 他不给他们任何东西,这显得太自私了。 注意:1) 其他系动词如,look,appear等也可用于此句型 2) 不定式作为句子成分时,动词用单数形式。 3) 当不定式作主语的句子中又有一个不定式作表语时,不能用It is… to…的句型 (对)To see is to believe. 百闻不如一见。 (错)It is to believe to see. 7.4 It's for sb.和 It's of sb. 1)for sb. 常用于表示事物的特征特点,表示客观形式的形容词,如easy, hard, difficult, interesting, impossible等: It's very hard for him to study two languages. 对他来说学两门外语是很难的。 2)of sb的句型一般用表示人物的性格,品德,表示主观感情或态度的形容词,如good, kind, nice, clever, foolish, right。 It's very nice of you to help me. 你来帮助我,你真是太好了。 for 与of 的辨别方法: 用介词后面的代词作主语,用介词前边的形容词作表语,造个句子。如果道理上通顺用of,不通则用for。如: You are nice. (通顺,所以应用of)。 He is hard. (人是困难的,不通 |
