    短文改错。
    I love camping. It is my favoritest way to spend the summer vacation. Last year, my family and I went
    camping in the countryside. It was one of the most excited experiences I had never had. We slept in a tent and went on a long walk every day. We cook over a fire and the food always tasted wonderfully. For a
    whole week, I saw lovely mountain views or breathed fresh air. At night, I heard the gentle wind blowing in the tree, and I felt so peaceful. It doesn’t cost many to camp, and what I believe it’s the best way to get
    close nature and enjoy its beauty.

形容词的概念:

形容词(adjective),简称adj.或a,形容词用来修饰名词或代词,表示人或事物的性质、状态,和特征的程度好坏与否,形容词在句中作定语、表语、宾语补足语。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。


形容词的作用与位置:

形容词是用来修饰名词的,常被放在名词前作定语,或放在系动词后面作表语。以下属几种特殊情况,须牢记;
(1)形容词短语作定语,定语后置。
如:a language difficult to master,
        a leaning tower about 180 feet high
(2)表语形容词(afraid、alike、alone、asleep、awake、alive等)作定语,定语后置。如a man alive。有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语,ill如作定语意为“bad”。
(3)用作定语,修饰由不定代词one、no、any、some和every构成的复合词如anything、something等时,通常后置。
如:I have something important to tell you.
(4)else常用作疑问代词和不定代词的后置定语。
(5)enough、nearby修饰名词前置或后置,程度副词一般位于形容词、副词前面,enough修饰形容词、副词时,必须后置。
(6)几个并列的形容词作定语,其语序通常为:限定语(The、A)+描绘性形容词+size(大小)+shape(形状)+age(年龄、时间)+color(颜色)+origin(国籍、来源)+material(材料)+purpose(目的)+名词。

口诀:
限定描绘大长高,形状年龄和新老;颜色国籍跟材料,作用类别往后靠。
如:a heavy black Chinese steel umbrella,
        the man's first tow interesting little red French oil paintings


形容词的用法:

1、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)Heisanillman. (对)Themanisill. (错)Sheisanafraidgirl. (对)Thegirlisafraid.
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:somethingnice

2、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 poorarelosinghope.穷人失去了希望。
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。如:the British,the English,the French,the Chinese. The English have wonderful senseofhumor.

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:
如:(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 .
如:The Times is a daily paper. 
        The Times is published daily.


形容词知识体系:

 


复合形容词的构成

(1)形容词+名词+ed:
          如:kind-hearted 好心的,white-haired 白发的
(2)形容词+形容词:
          如:red-hot 炽热的,dark-blue 深蓝的
(3)形容词+现在分词:
          如:good-looking 好看的,easy-going 随和的
(4)副词+现在分词:
          如:hard-working 勤劳的,fast-moving 快速转动的
(5)副词+过去分词:
          如:hard-won 得来不易的,newly-made 新建的
(6)名词+形容词:
          如:life-long 终生的,world-famous 世界闻名的
(7)名词+现在分词:
          如:peace-loving 爱好和平的,fun-loving 爱开玩笑的

          如:snow-covered 白雪覆盖的,hand-made 手工的
(9)数词+名词+ed:
          如:four-storeyed 4层楼的,three-legged 3条腿的
(10)数词+名词(名词用单数):
          如:ten-year 10年的,  two-man 两人的


程度副词的概念:

程度副词用来描述动作、行为或状态程度的副词称为程度副词。
absolutely完全地, almost几乎, amazingly令人惊异地, enormously非常地, enough充足地, entirely完全地, extremely极端地, fairly相当, fully完全地,
如:This task is extremely difficult. 这项任务极其艰难。
        You're entirely wrong. 你完全错了。

程度副词有于表示程度,常见的如:fairly, pretty, rather, quite, very, much, too, greatly, almost, nearly, half, highly, awfully, deeply, partly, perfectly, really等。使用时注意以下几点:
(1)程度副词主要用于修饰形容词和副词,有的还可修饰比较级(如much, rather等)和最高级(如quite, much, almost等):
如:Houses are much more expensive these days. 如今的房价贵多了。
        This is quite[much] the most expensive radio here. 这是这里最贵的收音机。
:quite有时也修饰比较级,但只用于quite better(身体康复)这一表达。

(3)个别的程度副词(主要是quite和rather)还可修饰名词(注意词序):
如:It's quite[rather] a good idea./ It's a quite[rather] good idea. 那可真是个好主意。
若此结构中没有形容词,则quite和rather则只能放在冠词之前:

介词和介词短语的概念:

介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类,短语或从句作它的宾语。介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。


误用介词的三种情况:

1、多用介词:

误:We discussed about the plan.
正:We discussed the plan. 我们讨论了计划。
误:Did he mention about the accident?
正:Did he mention the accident? 他提到那次事故了吗?

误:He has a great many of friends here. (比较a great number of)
正:He has a great many friends here. 他在这儿有很多朋友。

2、漏用介词:
漏用介词可能是受汉语意思的影响将不及物动词误用作及物动词,或是受相关结构的影响的影响而用错等:
误:This matter is difficult to deal. (deal with=处理)
正:This matter is difficult to deal with. 这事很难处理。
误:He is not a man to be depended.
正:He is not a man to be depended on. 他不是个可靠的人。
误:He took a cup of tea, and went on the story.

误:My mother still regards me a child. (比较consider…as中的as可省略)

误:They insisted sending a car over to fetch us.
正:They insisted on sending a car over to fetch us.他们坚持要派车来接我们。
误:What he says is worth listening.
正:What he said is worth listening to.他的话值得一听。

3、错用介词:
错用介词的情况比较复杂,可能是因受汉语意思的而错,也可能是因弄不清搭配关系而错,可能是混淆用法而错,也可能是受相关结构的影响而错,可能是忽略语境而错,也可能是想当然的用错:
误:She called on his office yesterday. (call on+人,call at+地点)
正:She called at his office yesterday. 她昨天去了他办公室拜访。
误:He is engaged with a nurse.
正:He is engaged to a nurse.他与一位护士订了婚。

误:We are familiar to his character.
正:We are familiar with his character.我们了解他的性格。
误:Help yourself with the fruit.
正:Help yourself to the fruit.吃点水果吧。


介词的宾语:

 1、名词或代词作介词宾语:
如:Are you interested in history? 你对历史感兴趣吗?
        Don't worry about it. 别为它担心。
注:若是人称代词用作介词宾语,要注意用宾格。
如:No one can sing like her. 没有人能像她那样唱歌。(不能用like she)
2、动名词作介词宾语:
如:He is good at telling stories. 他善于讲故事。

如:We can't regard the matter as settled. 我们不能认为这事已经解决。
        I take it for granted you have read the book. 我以为你读过这本书。
:过去分词用作介词宾语通常只见于某些固定结构中,如上面第1句涉及regard…as(认为…是)结构,第2句涉及take sth for granted(认为某事属实)。在其他情况下,介词后通常不直接跟过去分词作宾语,若语义上需要接过去分词(表被动),可换用“being+过去分词”:
如:He went out without being seen by the others.他出去了,没有被其他人看见。
4、从句作介词宾语:
如:He was not satisfied with what she said. 他对她说的不满意。
        I'm worried about where he is. 我担心他上哪儿去了。

误:He paid no attention to that she was poor.
正:He paid no attention to the fact that she was poor. 他根本不注意她很穷这一事实。
但有个别介词(如except)可接that从句。
比较:I know nothing about him except that he lives next door./I know nothing about him except for the fact that he lives next door. 我只知道他住在隔壁,其它的就不知道了。
5、不定式作介词宾语:
如:I had no choice but to wait. 除了等,我没有别的选择。 
       He wanted nothing but to stay there. 他只想留在那儿。
       They did nothing but complain. 他们老是一个劲地抱怨。 
       He never did anything but watch TV. 除了看电视,他从不干任何事。
:(1)介词后接不定式的情形通常只见于but, except等极个别个词。该不定式有时带to,有时不带to,其区别是:若其前出现了动词do,其后的不定式通常不带to;
若其前没有出现动词do,则其后的不定式通常带to。 
(2)介词后虽然通常不直接跟不定式作宾语,但却可接“连接代词(副词)+不定式”结构:
如:He gave me some advice on how to do it. 对于如何做这事他给我提了些建议。
6、形容词作介词宾语:
如:Her pronunciation is far from perfect. 她的语音远不是完美的。
        In short, we must be prepared. 总而言之,我们要有准备。
        Things have gone from bad to worse. 事情越来越糟。
:(1)有些形容词用作介词宾语可视为其前省略了动名词being:
如:He regarded the situationas(being) serious. 他认为形势严重。
        His work is far from(being) satisfactory. 他的工作丝毫不令人满意。 
(2)有些“介词+形容词”的结构已构成固定搭配:in full全部地,全面地,无省略地; in private私下地,秘密地; in particular特别地;in general一般地,通常地,概括地; in brief 简言之;in short总之,简言之; in vain徒然地,徒劳无益地;for fee免费地,无偿地; for certain肯定地,确切地;for sure肯定地,确切地; for short为了简短,简称;atl arge自由自在地,逍遥法外; by far…得多
7、副词作介词宾语:
如:I can't stay for long. 我不能久呆。 
        It's too hot in here. 这里面太热了。
        I looked every where except there. 除了那儿,我到处都看过了。
8、数词作介词宾语:
如:The city has a population of four million. 这座城市有四百万人口。
        He was among the first to arrive. 他是第一批到的。
9、介词短语作介词宾语:
如:Choose a book from among these. 从这些书中选一本吧。
        I saw her from across the street. 我从街的对面望见了她。
:通常可后接介词短语作宾语的介词是from, till, until, since, except, instead of等。
比较:I took it from the bed. 我从床那儿(或床上)拿的。
            I took it from under the bed. 我从床下拿的。 
10、复合结构用作介词宾语:
如:She had no objection to Mary marrying him. 她不反对玛丽与他结婚。
        She came in with a book in her hand. 她手里拿着一本书走了进来。
        All the afternoon he worked with the door locked. 整个下午他都锁着门在房里工作。

介词短语的句法功能:
1、表语:
如:He was with a friend. 他和一个朋友在一起。
        Health is above wealth. 健康胜过财富。
        This knife is for cutting bread. 这把小刀是用于切面包的。
:有些介词(如because of)引出的短语通常只用作状语,不用作表语:
误:His absence is because of the rain.
正:His absence is due to the rain. 他因雨未来。
但是,若主语是代词(不是名词),becauseof引出的短语可用作表语:
如:It is because of hard work. 那是因为辛苦工作的原因。
2、状语:

        Did you do this by design or by accident? 你这样做是有意的还是无意的?

4、宾语补足语:
如:I found everythingin good condition. 我发现一切正常。
       Her illness kept her in bed for a week. 她因生病在床上躺了一星期。
:用作宾语补足语的介词短语在相应的被动语态中则为主语补足语:
如:He was regarded as a hero. 他被看成是英雄。
5、宾语:
如:A man stepped out from behind the wall. 一个人从墙后走出来。
        He cannot spare anytime except on Sunday. 除星期日外,他抽不出时间。
6、主语:
如:Between6 and 7 suits me. 六点到七点对我比较适合。
        After the exams is the time to relax. 考试后是轻松一下的时间。
:介词短语通常不用作主语,尽管有时也像上面这样用作主语,但通常可视为是在一定的上下文中有所省略:
如:—When are we going to have the next meeting? 我们下次什么时候见面?
        —On Tuesday may be convenient. 星期二可能比较方便。
此句中onTuesday虽用作主语,但可视为是其前省略了meeting一词:
即:Meeting during the vacation may be convenient.


并列连词的概念:

连词是一种虚词,它不能独立担任句子成分而只起连接词与词,短语与短语以及句与句的作用。连词主要可分为两类:并列连词和从属连词。并列连词用来连接平行的词、词组和分句。如:and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both...and, notonly...butalso, either...or, neither...nor, (and)then 等等。


并列连词与并列结构:

并列连词引导两个并列的句子。
1)and与or:
判断改错:
(错) They sat down and talk about something.
(错) They started to dance and sang.
(错) I saw two men sitting behind and whisper there.
(对) They sat down and talked about something.
(对) They started to dance and sing.
(对) I saw two men sitting behind and whispering there.
解析:第一句:and连接两个并列的谓语,所以talk应改为talked。
            第二句:and连接两个并列的动词不定式,第二个不定式往往省略to,因此sang应改为sing。
            第三句:and连接感观动词saw后面的用作的宾补的两个并列分词结构,因此whisper应改为whispering。
注意:and还可以和祈使句或名词词组连用表示条件。(or也有此用法)
如:Make up your mind, and you'll get the chance.=If you make up your mind, you'll get the chance.
        One more effort, and you'll succeed.=If you make one more effort, you'll succeed.
2)both...and 两者都
如:She plays(both) the piano and the guitar.
3)not only...but(also), as well as 不但…而且
如:She plays not only the piano, but(also) the guitar.
注意:not only…but also关联两个分句时,一个分句因有否定词not而必须倒装。
如:Not only does he like reading stories, but also he can even write some.
4)neither...nor 意思为“既不……也不……”谓语动词采用就近原则,与nor后的词保持一致。
如:Neither you nor he is to blame.


比较so和such :

so与such的用法由不同词性决定。such是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副词。so还可与表示数量的形容词many,few,much,little连用,形成固定搭配。
构成:so+adj.
            such+a(n)+n.
            so+adj.+a(n)+n.
            such+n.(pl.)
            so+adj.+n.(pl.)
            such+n.(pl.)
            so+adj.+n.[不可数] 
            such+n.[不可数]
如:so foolish 
        such a fool  
        so nice a flower 
        such a nice flower 
        so many/few flowers 
        such nice flowers 
        so much/ little money.
        such rapid progress
        so many people
        such a lot of people
:so many 已成固定搭配,a lot of 虽相当于many,但a lot of为名词性的,只能用such搭配。 so...that与such...that之间的转换既为so与such之间的转换。


并列连词用法点拨:

1、表示并列关系:
1)or意思为“否则”。
如:I must work hard, or I'll fail in the exam.
2)either...or意思为“或者……或者……”。注意谓语动词采用就近原则。
如:Either you or I am right.
2、表示转折或对比关系:
1)but表示转折,while表示对比。
如:Some people love cats, while others hate them.
典型例题:
—Would you like to come to dinner tonight?
—I'd like to, ___ I'm too busy.
    A. and
    B. so
    C. as
    D. but
答案:D。but与前面形成转折,符合语意。而表并列的and,结果的so,原因的as都不符合句意。
2)not...but...意思为“不是……而是……” not和but后面的用词要遵循一致原则。
如:They were not the bones of an animal, but(the bones) of a human being.
3、表示原因关系:
1)for 判断改错:
(错)For he is ill, he is absent today.
(对)He is absent today, for he is ill.  for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。


并列连词知识体系

种类 用法 举例
并列连词 表示转折关系 yet, but等
表示并列关系 and, or, either...or..., as welll as等
表示因果关系 for, so等

比较and和or的用法:

1)并列结构中,or通常用于否定句,and用于肯定句。
2)但有时and也可用于否定句。请注意其不同特点:
如:There is no air or water in the moon.
        There is no air and no water on the moon.
在否定中并列结构用or连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。

典型例题

—I don't like chicken___fish.
—I don't like chicken, ___I like fish very much.
A. and;and
B. and;but
C. or;but
D. or;and
答案:C。否定句中表并列用or,but表转折。
判断改错:
(错)We will die without air and water.
(错)We can't live without air or water.
(对)We will die without air or water.
(对)We can't live without air and water.


动词过去式的概念:

用来表示动词过去时的动词形式,规则变化加是动词后加-ed,不规则的要单独记。


动词过去式变化规则及其读音规则:

一、规则动词的过去式变化如下:
1、一般情况下,动词词尾加-ed:
如:work-worked   play-played  wanted-wanted  act-acted
2、以不发音的-e结尾动词,动词词尾加-d:
如:live-lived     move-moved  taste-tasted    hope-hoped
3、以辅音字母+y结尾的动词,把-y变为-i再加-ed:
如:study-studied copy-copied  cry-cried   carry-carried
4、以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加-ed:
如:stop-stopped
5、不规则动词的过去式变化规律性不强,须多加记忆。
如:go-went     make-made     get-got    buy-bought   come-came    fly-flew

二、不规则动词的过去式的构成:

1、把动词原形中的i改为a,变成过去式。
如:begin—began,drink—drank,give—gave,ring—rang,sing—sang,sit—sat,swim—swam
2、把重读开音节中的i改为o,变成过去式。
如:drive—drove,ride—rode,write—wrote
3、改动词原形中的aw/ow为ew,变成过去式。
如:draw—drew,grow—grew,know—knew,throw—threw(动词show除外,show—showed)
4、动词原形中的e改为o,变成过去式。
如:get—got,forget—forgot
5、动词原形中的ee改为e,变成过去式。
如:feed—fed,meet—met
6、动词原形中的eep改为ept,变成过去式。
如keep—kept,sleep—slept,sweep—swept
7、动词原形中的eak改为oke,变成过去式。
如:break—broke,speak—spoke
8、动词原形中的ell改为old,变成过去式。
如:sell—sold,tell—told
9、动词原形中的an改为oo,变成过去式。
如:stand—stood,understand—understood
10、以ought和aught结尾,且读音是〔:t〕的过去式。
如:bring—brought,buy—bought,think—thought,catch—caught,teach—taught
11、以ould结尾且读音为〔ud〕的情态动词过去式。
如:can—could,shall—should,will—would
12、把动词原形中的o改为a,变成过去式。
如:come—came,become—became
13、在动词原形后加d或t变成过去式,并且发生音变。
如:hear〔hi〕—heard〔h:d〕,say〔sei〕—said〔sed〕,mean〔mi:n〕—meant〔ment〕
14、动词的过去式与动词原形一样。
如: let—let,must—must,put—put,read—read〔red〕
15、不符合上述规律的动词过去式。
如:am,is—was,are—were,build—built,do—did,eat—ate,fall—fell,feel—felt,find—found,fly—flew,
go—went,have/has—had,hold—held,leave—left,make—made,may—might,run—ran,see—saw,take—took

三:过去式“-ed”的发音规则:
(1)动词词尾为“t,d”时,发/id/音。
如:want→wanted(要)need→needed(需要)
(2)动词词尾为清辅音时,发/t/音。
如:help→helped(帮助)laugh→laughed(笑)look→looked(看) kiss→kissed(吻)wash→washed(洗)watch→watched(注视)
(3)动词词尾为t,d以外之浊辅音或元音时,发/d/音。
如:call→called(叫)stay→stayed(停留)cry→cried(哭)


be动词的过去式:

在没有实义动词的句子中使用be动词,am,is的过去式为was;are的过去式为were.请看如下句型的构成:
1、肯定句:主语+was(were)+宾语
例:I was late yesterday.(昨天我迟到了。)
2、否定句:主语+was(were)+not+宾语
例:We weren't late yesterday. (我们昨天没迟到)
3、疑问句:Was(Were)+主语+宾语
例:Were you ill yesterday?(你昨天病了吗?)
4、肯定回答:Yes, I was. (是的,我病了。)
      否定回答:No, I wasn't. (不,我没病。)
5、特殊疑问句:特殊疑问词+was(were)+主语+宾语
例:When were you born? 你是什么时候出生的?
【方法窍门】
be的过去式有四巧:
一是时间状语巧:表示过去的短语要记牢;
二是形式巧:单数was,复数were;
三是否定句结构巧:not紧跟was/were;
四是疑问句式巧:was/were向前跑(提前)。
【思路分析】
『一巧』 时间状语巧。一般过去时表示过去发生的动作或存在的状态,恰巧与表示过去的一些时间状语连用。
例如:yesterday, last night/week/month/year, last Saturday, the day beforey esterday, in 1998, five years ago等。
『二巧』 形式巧。它与一般现在时一样,形式多样:当主语是第一人称单数或第三人称单数时,谓语动词用was;主语是第二人称或其他人称复数时,谓语动词用were。
例如:I was in the classroom yesterday morning. 昨天早上我在教室里。
            He was at school last Tuesday. 上周二他在学校。
            They were over there a moment ago. 刚才他们在那边。
『三巧』 否定句结构巧。与动词be的一般现在时一样,它在动词后面加not即可变成否定句,并且was, were与not可以缩写成wasn't, weren't。即:主语+wasn’t/weren’t+表语+其他。
例如:I was not(=wasn't)here yesterday. 昨天我不在这儿。
            My parents were not(=weren't)at home last Sunday. 上周日我父母不在家。
『四巧』 疑问句式巧。把was, were提到句首,句末用问号即可变为一般疑问句。即:Was(Were)+主语+表语+其他?这恰巧与动词be的一般现在时的疑问句式相似。
例如:Were you at home the day before yesterday? 前天你在家吗?
            Was she late this morning? 今天早上她迟到了吗?
更巧的是疑问句的答语也相似,肯定回答用“Yes, 主语+was/were.”;否定回答用“No, 主语+wasn't/weren't.”。
例如:—Were Wei Hua and Han Mei here just now? —刚才魏华和韩梅在这儿吗?
            —Yes, they were./No, they weren't.是的,在这了。


现在分词的概念:

现在分词(PresentParticiple)(又称-ing形式),是分词的一种,是非限定动词,即在句子里面不能单独充当谓语,但能充当其它的一些成分(定语,表语,补语和状语)。一般式:doing;一般被动式:being done;完成式:having done;完成被动式:having been done。所有否定式都是在-ing前面加not。


现在分词的用法:

1)做表语:
如:He was very amusing.
        That book was rather boring.
很多动词的现在分词都可以作表语:exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.
2)作定语:
上面所出现的现在分词都可以用作定语,修饰一个名词:
如:That must have been a terrifying experience.
        I found him a charming person.
现在分词短语还可以放在名词的后面修饰名词,相当于一个定语从句:
如:There are a few boys swimming in the river.
        There is a car waiting outside.
3)作状语:
现在分词短语可以表示一个同时发生的次要的或伴随的动作:
如:Following Tom, we started to climb the mountain. 
        Opening the drawer, he took out a box.
        Taking a key out of his pocket, he opened the door.
现在分词短语还可以表示原因,相当于一个原因状语从句:
如:Not knowing her address, we couldn't get in touch with her.
        Being unemployed, he hasn't got much money.
现在分词短语还可以表示时间,相当于一个时间状语从句:
如:Hearing the news, they all jumped with joy.
        Returning home, he began to do his homework. 
        Jim hurt his arm while playing tennis.
        Be careful when crossing the road.
        Having found a hotel, we looked for some where to have dinner.
        Having finished her work, she went home.
4)作宾补:
现在分词在一些动词之后可以做宾语的补语:
例如:see, hear, catch, find, keep, have等。
如:I see him passing my house every day.
        I caught him stealing things in that shop.
        I smelt something burning.
        She kept him working all day.


现在分词其他用法解析:

1、现在分词一般式的用法:
现在分词的一般式所表示的动作与主语动作同时发生:
如:When we arrived, we found him sleeping. 我们到达时发现他在睡觉。
         Living in the 示的动作也可略早于或迟于谓语动作,但两者之间没有时间间隔:
如:Seeing nobody at home, he decided to leave a note. 发现没有在家,他决定留个字条。 
         He went home, finding the door locked. 他回到家,发现门是锁着的。当现在分词所表示的动作略迟于谓语动作时,现在分词通常位于句末。

2、现在分词完成式的用法:
现在分词的完成式主要表示发生在谓语动作之前的动作:
如:Having been there once, she knew the place quite well. 由于去过那儿一次,她对那地方很熟悉。
        Having failed twice, he didn't want to try again. 他已经失败了两次,不想再试了。
注:(1)现在分词的一般式和完成式均可表示已完成或先于谓语的动作,但有区别:现在分词所表示的动作虽然可以先于谓语动作,但两者之间没有时间间隔,而现在分词的完成式所表示先于谓语的动作则与谓语动作有一定的时间间隔:
如:Locking the door, he went out. 锁好门之后,他就出去了。
        Having invited him here to speak, we'd better go to his lecture. 既然我们请了他来作报告,我们最好去听一下。
有时即使是分词动作与谓语动作几乎同时发生,但如果要强调分词动作的完成性,也应用现在分词的完成式:
如:Having bought our tickets, we went into the theatre. 我们买好票后就走进剧场。
(2)现在分词的完成式一般不用作定语:
误:Do you know anyone having lost a cat? 你知道有谁丢了一只猫吗?
误:I want to talk to the person having broken the window. 我想同打破窗户的人谈谈。
若将以上现分词的完成式改为一般式也不可以(因为现在分词作后置定语时通常只表示与谓语动作同时或几乎同时发生的动作,而不能先于谓语动作而发生):
误:I want to talk to the person breaking the window.

3、现在分词被动式的用法:
当要表示一个被动动作时,现在分词就用被动形式。现在分词的一般式和完成式均有被动式形式:
(1)现在分词一般式的被动式:主要表示现在正在进行的动作,也可表示与谓语动作同时发生的动作:
如:Who is the woman being operated on? 正在动手术的女人是谁?
         I saw him being taken away by the police. 我看见他被警察带走。
:有时现在分词一般式的被动式所表示的动作也可发生在谓语动作之前(此时的现在分词通常用于表示原因,且多为状态动词):
如:Not having a car, he finds it difficult to get around. 由于没车,她感到行动很困难。
(2)现在分词完成式的被动式:主要表示发生在谓语动词之前且已经完成的动作。
如:The subject having been opened, he had to go on with it. 话题已经开始了,他不得不谈下去。
        Having been written inhaste, the book has many mistakes. 这书因写得仓促,所以错误不少。
比较:Being so ill, she can't go to school. 由于病得那么严重,她不能去上学。
            Having been ill for a long time, he needed time to recover. 由于病了很长时间,他需要一段恢复的时间。


肯定句的概念:

句子中不含否定词的就称为肯定句。肯定句的基本结构为:主语+谓语,陈述句的肯定形式分两种,一种为正常语序,一种为倒装语序。
例如:I have heard a lot that way. 
            In front of the car was Mike.
 


用于肯定句的常见结构:

1、already:
在通常情况下,already(已经)主要用于肯定句,一般不用于否定句或疑问句。
如:误:He hasn' tarrived already.
        正:He hasn't arrived yet. 他还没有到。
:有时用于否定句或疑问句中,主要表示惊讶。
如:Is he back already? 他怎么就回来了。
        Haven't you seen him already? 难道你还没见到好?
2、excellent:
excellent意为“极好的”,含有绝对无疑的意思,通常只用于肯定句,不用于否定句。
如:误:The film is not excellent.
        正:The film is not very good. 这部电影不是很好。
:excellent通常也不用于疑问句、条件句等。
3、hurry up:
hurry up主要用于肯定句(尤其是肯定的祈使句),一般不用于否定句。在否定句中,用hurry即可。
如:误:Don't hurry up; we have enough time.
        正:Don't hurry; we have enough time. 别急,我们有的是时间。
4、plenty(of):
在通常情况下,plenty(of)用于肯定句中,而不用于否定句中。
如:误:Have you plenty of food for the holidays?
        正:Have you enough food for the holidays? 你有足够的食物供假期里吃吗?
:在否定句或疑问中用enough, much, many等代之。具体地说,疑问句中通常用enough代替,否定句中通常用much,many代替。
比较:There is plenty of time. 时间还很多。 
            There isn't much time. 时间不多了。 
            Is there enough time? 时间还够吗?
5、some:
在通常情况下,some用于肯定句中,在否定句或疑问句中要用any代之。
如:误:I haven't some question to ask.
        正:I haven't any question to ask. 我没有问题要问。
:some有时也用于否定句,那多半有某种特殊的原因。
比较:I don't like any of the books. 这些书中我一本也不喜欢。
            I don't like some of the books. 这些书中有几本我不喜欢。
            I don't like some one of the books. 这些书中某一本我不喜欢。
另外,some有时也可用于疑问句,如希望得到肯定回答的疑问句,或表示请求或建议等。
如:May I have some paper? 我可以拿些纸吗?
        Why not give her some flowers? 为什么不给她送些花呢?
表示“也”的副词also, too, as well通常不用于否定句,而主要用于肯定句或疑问句。
如:误:I don't like the film too. 
        误:I don't also like the film as well.
        误:I don't like the film as well.
        正:I don't like the film either. 我也不喜欢这部电影。
:also和too有时可用于肯定句后所接的否定句中,表示“没有也……”。
如: Heleftbutshedidn’talsoleave.他走了,但她没有也一起走。
          He bought a computer, but she didn't too. 他买了台电脑,但她没有也买台电脑。
另外,在正式文体中,also, too有时可用于否定词之前。
如:I also don't like it. 我也不喜欢它。
        I, too, have never met anyone like him.我也是,没见过和他一样的人。
