2.1 人称代词的用法
1)人称代词的主格在句子中作主语或主语补语,例如:
  John waited a while but eventually he went home.
  约翰等了一会儿,最后他回家了。
  John hoped the passenger would be Mary and indeed it was she.
  约翰希望那位乘客是玛丽,还真是她。
说明:在复合句中,如果主句和从句主语相同,代词主语要用在从句中,名词主语用在主句中,例如:
  When he arrived, John went straight to the bank.
  约翰一到就直接去银行了。
2)人称代词的宾格在句子中作宾语或介词宾语,但在口语中也能作主语补语,第一人称在省略句中,还可以作主语,例如:
 I saw her with them, at least, I thought it was her.
 我看到她和他们在一起,至少我认为是她。(her做宾 语,them做介词宾语,her作主语补语)
   a. -- Who broke the vase? --谁打碎了花瓶?
   b. -- Me.    --我。(me作主语补语= It's me.)
说明:在上面两例句中,her和me分别作主语补语。现代英语中多用宾格,在正式文体中这里应为she和I。

2.2 人称代词之主、宾格的替换
1) 宾格代替主格
  a.在简短对话中,当人称代词单独使用或在not 后,多用宾语。
   ---- I like English.   --我喜欢英语。
   ---- Me too.       --我也喜欢。
   ---- Have more wine?   --再来点酒喝吗?
   ---- Not me.       --我可不要了。
  b.在表示比较的非正式的文体中,常用宾格代替主格。 但如果比较状语的谓语保留,则主语只能用主格。
    He is taller than I/me.
    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)

2.3 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。

2.4 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。

2.5 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。

2.6 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.

2.7 反身代词
1) 列表

   absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave

   Please help yourself to some fish.  请你随便吃点鱼。
  b. 用于及物动词+宾语+介词

 3) 作表语; 同位语
   be oneself: I am not myself today.  我今天不舒服。
   The thing itself is not important.  事情本身并不重要。

No one but myself (me) is hurt.
注意:
  a. 反身代词本身不能单独作主语。
   (错) Myself drove the car.
   (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。

2.8 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。

2.9 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 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)

2.10 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。

2.11 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,见下:
      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. He's not the man he was.
他变化很大,已不是过去的他了。

  many a (=many)

2) Not until the early years of the 19th century ___ what heat is.
  A. man did know  B. man know  C. didn't man know  D. did man know
 答案D.  看到Not until…的句型,我们知道为一倒装句,答案在C,D 中选一个。
 改写为正常语序为,Man did not know what heat is until the early years of the 19th. 现在将not提前,后面就不能再用否定了,否则意思就变了。
2.23 以否定词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
  Not only did he refuse the gift, he also severely criticized the sender.
  Hardly had she gone out when a student came to visit her.
  No sooner had she gone out than a student came to visit her.
典型例题
No sooner___ than it began to rain heavily.
A. the game began      B. has the game begun
C. did the game begin    D. had the game begun
答案D. 以具有否定意义的副词放在句首时,一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。
注意:只有当Not only… but also连接两个分句时,才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语,不可用倒装结构。
  Not only you but also I am fond of music.

2.24 so, either, nor作部分倒装
表示"也"、"也不" 的句子要部分倒装。    
  Tom can speak French. So can Jack.
  If you won't go, neither will I.
典型例题
 ---Do you know Jim quarrelled with his brother?
 ---I don't know, _____.
 A. nor don't I care  B. nor do I care  C. I don't care neither  D. I don't care also
答案:B. nor为增补意思"也不关心",因此句子应倒装。A错在用 don't 再次否定, C neither 用法不对且缺乏连词。 D缺乏连词。
  注意: 当so引出的句子用以对上文内容加以证实或肯定时,不可用倒装结构。意为"的确如此"。
  Tom asked me to go to play football and so I did.
  ---It's raining hard.   ---So it is.
2.25 only在句首要倒装的情况
Only in this way, can you learn English well.
  Only after being asked three times did he come to the meeting.
  如果句子为主从复合句,则主句倒装,从句不倒装
  Only when he is seriously ill, does he ever stay in bed.

2.26 as, though引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。
注意:
    1) 句首名词不能带任何冠词。
    2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语,  随实义动词一起放在主语之前。
   Try hard as he will, he never seems able to do the work satisfactorily.
注意:
  让步状语从句中,有though,although时,后面的主句不能有but,但是 though 和yet可连用。

2.27 其他部分倒装
1)  so… that 句型中的so 位于句首时,需倒装。
   So frightened was he that he did not dare to move an inch.
2) 在某些表示祝愿的句型中:
  May you all be happy.
3) 在虚拟语气条件句中从句谓语动词有were, had, should等词,可将if 省略,把 were, had, should 移到主语之前,采取部分倒装。
  Were I you, I would try it again.
典型例题:
1) Not until the early years of the 19th century___ what heat is  
A. man did know  B. man knew  C. didn't man know  D. did man know
答案为D. 否定词Not在句首,要求用部分倒装的句子结构。
2) Not until I began to work ___ how much time I had wasted. 
A. didn't I realize  B. did I realize  C. I didn't realize D. I realize
 答案为B。
3) Do you know Tom bought a new car?
 I don't know, ___.
 A. nor don't I care  B. nor do I care 
 C. I don't care neither D. I don't care also
 解析:答案为B. 句中的nor引出部分倒装结构,表示"也不"。由 so, neither, nor引导的倒装句,表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。

2.28 定语从句
定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
  关系代词有:who, whom, whose, that, which等。
  关系副词有:when, where, why等。

2.29 关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。
1)who, whom, that
  这些词代替的先行词是人的名词或代词,在从句中所起作用如下:
  Is he the man who/that wants to see you?
他就是你想见的人吗?(who/that在从句中作主语)
  He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。(whom/that在从句中作宾语)
2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换), 例如:
  They rushed over to help the man whose car had broken down.  那人车坏了,大家都跑过去帮忙。
  Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。
3)which, that
  它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如:
  A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。(which / that在句中作宾语)
  The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语)

2.30 关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。
1)when, where, why
  关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如:
  There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
  Beijing is the place where (in which) I was born. 北京是我的出生地。
  Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?
2)that代替关系副词
  that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略,例如:
  His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
  He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。

2.31 判断关系代词与关系副词
方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如:
  This is the mountain village where I stayed last year.
  I'll never forget the days when I worked together with you.
  判断改错(注:先显示题,再显示答案,横线;用不同的颜色表示出。)
  (错) This is the mountain village where I visited last year.
  (错) I will never forget the days when I spent in the countryside.
  (对) This is the mountain village (which) I visited last year.
  (对) I'll never forget the days (which) I spent in the countryside.
  习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。
  方法二: 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。
例1. Is this museum ___ you visited a few days age?
  A. where B. that  C. on which  D. the one
例2. Is this the museum ____ the exhibition was held.
  A. where  B. that  C. on which  D. the one
答案:例1 D,例2 A
例1变为肯定句: This museum is ___ you visited a few days ago.
例2变为肯定句: This is the museum ___ the exhibition was held.
  在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D。
  而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语。而此题中,介词on 用的不对,所以选A。
  关系词的选择依据在从句中所做的成分,先行词在从句中作主、定、宾语时,选择关系代词 (who, whom, that, which, whose); 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) 。

2.32 限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如:
   This is the house which we bought last month.   这是我们上个月买的那幢房子。(限制性)
   The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的。(非限制性)
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如:
   Charles Smith, who was my former teacher, retired last year. 查理•史密斯去年退休了,他曾经是我的老师。
   My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
   This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数,例如:
   He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。
   Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。
说明:关系代词that和关系副词why不能引导非限制性定语从句。

2.33 介词+关系词
1)介词后面的关系词不能省略。
2)that前不能有介词。
3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
  This is the house in which I lived two years ago.
  This is the house where I lived two years ago.
  Do you remember the day on which you joined our club?
  Do you remember the day when you joined our club?

2.34 as, which非限定性定语从句
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。
  As we know, smoking is harmful to one's health.
  The sun heats the earth, which is very important to us.  
典型例题 
1)Alice received an invitation from her boss, ___came as a surprise.
A. it  B. that  C. which  D. he
  答案C. 此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。
2)The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
  答案B。which可代替句子,用于非限定性定语从句,而what不可。That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。
3)It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which  C. as  D. it
 答案B.
  as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:
 (1) as 引导的定语从句可置于句首,而which不可。
 (2) as 代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which.。
  在本题中,prevent由于是行为动词,所以正确选项应为B。
As 的用法
例1. the same… as;such…as 中的as 是一种固定结构, 和……一样……。
   I have got into the same trouble as he (has).
例2. as可引导非限制性从句,常带有'正如'。
  As we know, smoking is harmful to one's health.
  As is know, smoking is harmful to one's health.
 As是关系代词。例1中的as作know的宾语;例2中,它充当从句的主语,谓语动词know要用被动式。
2.35 先行词和关系词二合一
1)Whoever spits in public will be punished here.
   (Whoever 可以用 anyone who 代替)
 2)The parents will use what they have to send their son to technical school.
  (what 可以用all that代替)
返回顶端〉〉
2.36 what/whatever/that...
1)Whoever spits in public will be punished here.
   (Whoever 可以用 anyone who 代替)
 2)The parents will use what they have to send their son to technical school.
  (what 可以用all that代替)

2.37 关系代词that的用法
1)不用that的情况
  a) 在引导非限定性定语从句时。
    (错) The tree, that is four hundred years old, is very famous here.
  b) 介词后不能用。
     We depend on the land from which we get our food.
     We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况
  a) 在there be 句型中,只用that,不用which。
  b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
  c) 先行词有the only, the very修饰时,只用that。 
  d) 先行词为序数词、数词、形容词最高级时,只用that。.
  e) 先行词既有人,又有物时。
举例:
  All that is needed is a supply of oil.
  所需的只是供油问题。
  Finally, the thief handed everything that he had stolen to the police. 
  那贼最终把偷的全部东西交给了警察。

   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:

 The chair looks rather hard, but in fact it is very comfortable to ___. 
 A. sit  B. sit on  C. be seat  D. be sat on
答案:B. 如果不定式为不及物动词,其后应有必要的介词。当动词与介词连用时,常位于"形容词+动词不定式"结构的末尾。

2.45 用作介词的to

 =They were made to work the whole night.
4) would rather,had better:
5) Why… / why not…:
6) help 可带to,也可不带to, help sb (to) do sth:
7) but和except:but前是动词do时,后面出现的动词用不带to的动词不定式。
8) 由and, or和than连接的两个不定式,第二个to 可以省去:
9) 通常在discover, imagine, suppose, think, understand等词后,可以省去to be: 
   He is supposed (to be) nice. 他应该是个好人。
举例:
   He wants to move to France and marry the girl.
He wants to do nothing but go out.
比较:  He wants to do nothing but go out.

 She wants to learn English well.

2.54 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。

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

2.55 什么是助动词

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。)

2.60 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.。

2.61 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)。
