  PETS-3考试中语法占到了很大比重。而各位考生由于很久未系统的复习英语,常常对考试中出现的语法题目感到很“苦手”。

2016下半年公共英语三级考试经典语法汇总

  本系列文章将对PETS-3常见的一些语法问题进行一下辅导,希望能对考生应付这些题目有所帮助。

  一、形容词和副词

  A. 形容词

  1、 形容词的用法

  形容词是用来修饰、描绘名词的,通常在句中作定语、表语或宾补,有时还可作状语。如:

  He is honest and hardworking.

  I found the book interesting.

  某些形容词与定冠词连用表示一类人作主语时,谓语通常用复数形式。如:

  The rich and the poor live in different parts of the city.

  The English like to be with their families.

  多个形容词作定语修饰名词的顺序:

  冠词+序数词+基数词+性质状态(描述性)+形状大小+新旧老少+颜色+国籍+材料+名词。如: the second five interesting big new red Chinese wall papers.

  2、 形容词比较等级的形式

  (1) 规则形式

  一般说来,单音节词及少数双音节词在后加-er; --est 来构成比较级和最高级;其他双音节词及多音节词在前加more, most.如:

  great-greater-greatest

  busy-busier-busiest

  important-more important-(the)most important

  (2) 不规则形式

  good (well)-better-best

  bad (ill)-worse-worst

  many (much)-more-most

  little-less-least

  (3) 形容词比较等级的用法

  ①表示两者的比较,用形容词的比较级+than. 如:

  He is cleverer than the other boys.

  This one is more beautiful than that one.

  ②表示两者以上的比较,用"the +形容词最高级(+名词)+of(in) …"如:

  He is the cleverest boy in his class.

  ③表示两者是同等程度,用"as +形容词原级+as". 如:

  He is as tall as I.

  I have as many books as you.

  ④ 越… 越…

  例如:The more I learn, the happier I am.

  ⑤ You can never be too careful. 越小心越好

  又如:You can never praise the teacher too highly.

  你怎么赞扬这个老师也不过分。

  ⑥ I have never spent a more worrying day.

  那一天是最令我担心的.一天。

  I have never had a better dinner.

  这是我吃过的最好的一顿饭。

  ⑦ My English is no better than yours.

  我的英语和你的英语都不怎么样。

  B.副词

  1、 副词的种类

  (1) 时间副词 如:ago, before, already, just, now, early, late, finally, tomorrow等

  (2) 地点副词 如:here, there, near, around, in, out, up, down, back, away, outside等。

  (3) 方式副词 如:carefully, angrily, badly, calmly, loudly, quickly, politely, nervously等。

  (4) 程度副词 如:almost, nearly, much, greatly, a bit, a little, hardly, so, very等。

  2、 副词比较等级的用法

  其用法与形容词相似,只是副词最高级前可省略定冠词。如:

  Of all the boys he sings (the) most beautifully.

  We must work harder.

  3、 某些副词在用法上的区别

  (1) already, yet, still

  already表示某事物已经发生,主要用于肯定句;yet表示期待某事发生,主要用于否定句和疑问句;still表示某事还在进行,主要用于肯定句和疑问句,有时也可用于否定句。如:

  We've already watched that film.

  I haven't finished my homework yet.

  He still works until late every night.

  (2) too, as well, also, either

  too, as well和 also用于肯定句和疑问句,too和as well多用于口语,一般放在句末,而also多用于书面语,一般放在句中与动词连用。either用于否定句和否定的疑问句,往往放在句末。如:He went there too.

  He didn't go there either.

  I like you as well.

  I also went there.

  (3) hard, hardly

  hardly意为"几乎"与hard在词义上完全不同。如:

  I work hard every day.

  I can hardly remember that.

  (4) late, lately

  lately意为"最近、近来",late意为"晚、迟"。如:

  He never comes late.

  Have you been to the museum lately?

  例1 Tom's father thinks he is already ____

  A high enough B tall enough

  C enough high C enough tall

  解析:该题正确答案是B。修饰人高用tall, 而建筑物的高用high,并且enough修饰形容词要放在形容词后面。因此该题选B。

  例2 ____ the worse I seem to be.

  A When I take more medicine

  B The more medicine I take

  C Taking more of the medicine

  D More medicine taken

  解析:该题正确答案为B。"the+形容词比较级+… , the +形容词比较级+…"意为越…,越…。该句意为:吃的药越多,我的病越是加重。

  例3"I haven't been to London yet".

  "I haven't been there ____".

  A too B also C either D neither

  解析:该题正确答案为C。A和B都用于肯定句中。D-neither本身意为否定"两者都不",而C-either则用于否定句中,意为"也"。

  例4 Mr Smith was ____ moved at the news.

  A deep B deeply C very deep D quite deeply

  解析:该题正确答案为B。A. deep用于副词时,修饰具体的深,如dig deep,而B-deeply则修饰表示感情色彩的词,如该题为deeply moved.另如deeply regret等。而D-quite和deeply均为副词,不能互相修饰。

  二、it 与there be的用法

  I.要点

  1、it的用法

  (1)用作人称代词,代替前文提到的无生命的事物,动植物、婴儿及指示代词this, that,如,

  I have a new pen. It is beautiful.

  The Browns have a new baby. It's cute.

  (2)用来表示时间、天气、距离等,如,It's twelve o'clock now.

  It's fine today.

  (3)用作引导词,代替由不定式,ing形式或从句表示的真正的主语或宾语,如,

  It's no good telling him that.

  It's necessary for you to do so.

  (4)用在强调结构中,构成强调句式:It is/was +被强调部分+that/who/whom +句子其余部分,可强调除谓语以外的句子其他成分,如,

  It was this morning that I saw him in the street.

  It was I who saw him in the street this morning.

  It was in the street that I saw him this morning.

  It was him whom I saw in the street this morning.

  2、there be句型

  英语表示某时某处或某物时,常用there be句型,这是一种倒装结构,如,

  There are a lot of students playing on the ground.

  There is going to be a test this afternoon.

  当主语有两个或两个以上时,动词be常和最近的那个主语取得一致,如,

  There is a pen and three pencils in the pencil-box.

  There isn't a desk, a bench and three chairs in the room.

  There are lots of people like it, aren't there?

  there be句型,谓语动词除be之外,还可用其他表示存在,位置移动等意义的不及物动词或词组,如exist, stand, lie, enter, come, happen to be, appear to be等,如,

  There stands a house at the foot of the hill.

  there be句型表示"存在"而have表"有"、"拥有",所以there be中 be不能换成have,但当have表示事物的特征时,可用"主语+have"结构替换there be 句型,如:

  There are five doors in the house.

  The house has five doors.

  there be 的其它句型:

  1、There must be a meeting in the office.

  2、There have been great changes since 1979.

  3、There being no bus, we had to walk home.

  I. 例题

  例1 ____ that he went to sleep.

  A It was until midnight B That was until midnight

  C It was not until midnight D That was not until midnight

  解析:该题答案为C。强调until结构时,要将否定词not移到until前。又如:He didn't leave until twelve 改为It was not until twelve that he left.

  例2 There are a lot of students ____ in the class room.

  A talk B talking C talked D to talk

  解析:该题正确答案为B。 There be句型为倒装句,可换为A lot of students are talking in the class room. 又如:There is a lot of noise heard out in the street.

  三、连词

  1、 连词的种类

  (1) 并列连词用来连接并列关系的词、短语或分句,如and, for, or, both…and, either…or, neither…nor等。

  除了从属连词(引导状语从句)外,还有其它可以用来引导从句的词类。它们是连接代词和连接副词(引导名词性从句),关系代词和关系副词(引导定语从句)。
