1、00015英语二重点语法 (结合考题解说)综合英语(二)常考语法为:名词单数变复数,定语从句,虚拟语调,反意疑问句,非谓语动词,时态,名词性从句,形容词副词比较级,主谓一致,倒装等等。下面我们把这些语法项目进行详细有重点解说。名词1. 大多数集体名词可作单数,也可作复数,如: army , audience , class , committee , crew ( 全体船员,乘务员 ) , crowd , faculty , family , government , group , orchestra , team , union 等。强调节体时谓语动词用单数,强调个体时谓语动词用复数。如:
2、 The government is paying close attention to economic development.The government are having a heated discussion on this matter. 2.有些名词形式为复数,却用作单数,如 :electronics( 电子学 ) , mathematics( 数学 ) , optics( 光学 ) , politics , statistics( 记录学 ), economics (经济学), physics 等。例如 : Linguistics is a difficult subjec
3、t to study.3. 名词作定语时,除了man和woman要和中心词一起变成复数之外,其他修饰词不能变成复数。例如a woman teacher - two women teachersa man doctor - two men doctorsa girl student - five girl studentsa boy student -six boy students4. 复合名词复数只把其中所包括主体名词变成复数。如 : looker(s)-on , runner(s)-up , sister(s)-in-law , editor(s)-in-chief , passer(s)
4、-by , grand-child(ren) , shoe lace(s) , blood type(s) 等。5. 如果没有主体名词,就在最后一种词上加复数词尾。如 :go-between(s) , drawback(s), grown-ups “Of+抽象名词”相称于形容词Of interest-interesting Of importance-important Of value-valuableOf necessity-necessaryOf possibility-possibleOf great importance- greatly important/very importa
5、ntOf no value-valueless牢记invaluable=priceless这里重要讲一下 不定代词some和any。普通some用于必定句,any 用于疑问句和否定句。但在下列状况下例外:(1)在表达祈求、建议时,some及其派生词可以用于疑问句。如: Would you like some coffee? Can somebody come and help me? Could you lend me some books? Why dont you buy some flowers for her birthday?注意“any +单数名词”和“any other +单数名
6、词”区别。当前用两个例子进行阐明。 China is larger than any other country in Asia. (China belongs to Asia.)China is larger than any country in Africa. (China does not belong to Africa.)(2)any及其派生词用于必定句时,起强调作用,意思是 “任何” .如:You can come any day you like. 你哪天来都行He is taller than any of the other boys in the class. (any
7、of the other boys=any other boy)形容词和副词如下状况形容词惯用于后置定语 : 1) 某些表语性形容词要后置,如 :present (到场,出席) , available , involved , concerned , etc 。2) 形容词修饰不定代词 something , anything , everything 时要后置。例如 : There was something wrong with her. I came across a tricky question hard to answer. I wondered if there was a ro
8、om available. 注意enough位置:enough 修饰名词时放在名词前后均可,修饰形容词或副词时要放在背面。如: enough water /water enough careful enough/ well enough形容词和副词原级比较由 “as + 形容词或副词原级 ( 或后跟名词或短语 )+as” 构成, “asas” 前可加 not , just , almost , nearly , quite , twice , several times 等词修饰。否定式中 not 背面 as 可改为 so 。如:He is as tall as I.He is not as/
9、as careful as his brother.形容词与副词比较级形式为 :“ 形容词 ( 副词 ) 比较级 +than+” ,应注意 than 前后相比较人或物要一致 (否则没有可比性)。比较级前可以跟 even , much , stilI, far, a lot 等副词修饰比较级,表达强调。You voice is more beautiful than your classmates/that of your classmates.The population in China is much larger than that in America.The values of th
10、e young differ from those of their elders. 不可数名词或名词单数,背面用that代替,可数名词复数背面用those代替。注意某些以-ior结尾来自于拉丁语单词,虽表达比较含义,但背面要用to而不是than。惯用有七个:be junior to -be younger than be senior to -be older than be posterior to -be later than be anterior to -be earlier than be prior to -be earlier than/be more important th
11、an be inferior to -be worse than be superior to -be better than还要注意比较级重要构造:the +比较级, the +比较级 ( 越 就越 ) ,常考选取或翻译。如:The more careful you are, the fewer mistakes you make.The earlier you come, the better (it is).形容词与副词最高档形式分别为 :“the+ 形容词最高档 + 名词十范畴表达 ” 和 “ 副词最高档十名词 + 范畴表达 ” ,副词比较级和最高档不需要加 the 。例如 : We
12、are the happiest when staying with friends. I carried out the task more successfully than he had expected. Most 有时并不都是最高档形式,相称于very,该用法比较正式。如:It is a most touching film. 这是一部非常动人电影。They shall most certainly come. 她们很也许回来。时态国考中考试重点是完毕时态,当前我们详细讲完毕时态用法。只有延续性动词可以和时间段连用,瞬间动词要改为相应持续性表达状态短语。die-be deadleav
13、e/go-be awaybuy/borrow-keep/havestart/begin-be on注意重要句型:It is (has been)since这一构造也惯用于当前完毕时。It has been (也可用is) a long time since they last met each other.“This/It/That be the first (second) time that”句型中,从句惯用完毕时态。例如:Is this the first time that you have visited Hong Kong?This will be the second time
14、that I have broken a cup this week.That was the third time he had been interrupted that afternoon. *当前完毕进行时表达一种不间断动作,因而在提到做某事次数或所做事情种类时,不能用该时态,而只能用当前完毕时I have knocked at the door five times, but Im afraid nobody is in.The pop singer has sung three songs.关于过去完毕时1. 由had +过去分词构成,表达在过去某一时刻此前已经完毕动作,常与由by
15、, before,until等介词或连词引起表达到过去某一时间为止时间状语连用。The girl had learned a lot of English words before she went to school.2.用在表达与过去状况相反虚拟句从句中。If he had studied hard last term, he would have passed the examination.I wish I had gone to the party last night.关于将来完毕时由shall (will) + have +过去分词构成,表达将来某个时间之前会发生或也许完毕事情,
16、常与by, before, when等介词或连词引导表达将来时间短语或从句连用。 When we get there theyll probably have left.By the end of this century China will have become one of the strongest and wealthiest country in the world.下面我们要讲是语法中重中之重:情态动词+完毕式(1)could+have+过去分词 有时表达过去时间,阐明某事也许已发生,有时也表达与事实相反,表达本来有能力做某事,但却未做。例 What happened in t

33、s a teacher. -The school in/at which I am studying is a key school.解题要诀:掌握惯用介词基本用法 掌握惯用动词,形容词与介词之间固定搭配非限定性定语从句1.当指物时,不能用that只能用which2.which有时用来指整个句子或句子一某些。e.g. He died suddenly, which made her very sad. he said last night he went to sleep with his clothes on, which was very uncomfortable.关系词使用一看先行词,
34、二看关系词在从句中作用,在此基本上熟记几种惯用固定句式,如:the same as , such asThe film is the same as we have expected.关系词在句中做定语 whose应当熟悉关系词做定语时各种变体。 the office whose windows are broken the office the windows of which are broken “介词 + which/whom”构造做关系词A 介词是句中短语搭配一某些 ,如pay attention to, take care of 等固定短语动词,在定语从句中普通不适当将介词与动词分

36、lar with young people, _ which this is an example.ofD 有时介词与先行词构成短语 It is useful to be able to predict the extent _ which a price change will affect supply and demand. A. from B. with C. to D. forC. toas/which引导定语从句区别(1)位置不同:as可置于句首,也可置于句中,而which只能放在句中。(2)指代不同。 as引导定语从句时,其先行词为整个主句。which引导非限制性定语从句,其先行
37、词也可以是主句或主句中一某些。(3)与积极动作先后不同:as从句表达行为经常是在主句行为之前,而which引导定语从句表达却在主句之后,表达持续发生事情或成果等。As was expected, the England team won the football match. He promised to help me, which he did. He was often late for work, which cost him his job.注意先行词为时间、地点或因素时,关系词选用 如果用when, where 或why,关系词在从句中应当是做状语,否则话则应当用which / t
38、hat等。例如: I will never forget the days _ I spent with my friends in the country.that/which/ exercises1.

41、 home, his father was already dead. We shall have completed the work by the time he _ back next week. (/4)A. will come B. comesC. is coming D. will have comeBAs, when, while 虽然都表达时间,但是有区别As 多用于口语,强调“同一时间”或“一先一后”例:1.As I was going out, it began to rain.(as强调两个动作紧接着发生)2. As spring warms the good earth
42、, all flowers begin to bloom.(在这里是“随着”意思)When 强调特定期间例:1.When he was eating his breakfast, he heard the door bell rang.While 也表达同一时间,但表达不是一点,而是一段,因此位于谓语动词必要为延续性动词形式例:While he was eating his breakfast, his friend came to visit him.注意 notuntil 正常构造、倒装构造、强调构造、和until置于句首用法。He didnt go to sleep until he h
43、ad finished his homework. (正常构造)Not until he had finished his homework did he go to sleep. (倒装构造)It was not until he had finished his homework that he went to sleep.(强调构造)Until he had finished his homework he didnt go to sleep. (until置于句首)因素状语从句,关联词有because, as since 等because, as ,since三者区别:because 语调最强,重在交待因素,以why引导疑问句只能because用来回答;其前可用only, just等词强调;可用在 It isthat强调句型中。如:You shouldnt get angry just because some people speak ill of you.as 一词语调最弱,表达明显因素。如:As she was in a hu
