考点名称:系动词
- 系动词:
亦称连系动词,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(形容词),构成系表结构说明主语的状况、性质、特征等情况。
be(是)是最基本的系动词。小学涉及到的系动词需要掌握的am, is, are
如:I am from Beijing. 我来自北京。
My mother is a teacher. 我的妈妈是一位老师。
除了系动词be,常用的系动词还有look(看起来)、sound(听起来)、feel(感觉到)、become(变成)、smell(闻起来)等。
例:The boy looks very happy. 这个男孩看起来很高兴。
The dish smells good. 这盘菜闻起来很香。 be动词意思和用法:
一般的意思是:
是,此种用法,有多种变化形式,is,am,are,was,were,being,been,to be.
另外,be动词还有成为的意思。
根据句子中不同的人称、数和时态,应该选择相应的be动词。<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />要看句语的时态:
如果是一般过去时,就用was/were
如果是一般现在时,就用am/is/are
如果是一般将来时,就用will be
然后看主语的人称及复数形式:
一般过去时:
第一人称和第三人称的单数形式,则用was
第一人称和第二人称、第三人称的复数,则用were
一般现在时:
第一人称单数形式,用am
第三人称单数形式,用is
第一人称复数、第二人称、第三人称的复数形式,则用are
一般将来时:
will be
一般时态有关be动词的口诀:
我用am,你用are,is连接他/她/它,复数形式就用are
be动词的用法:
现在时 I am, you are, he is, we are, you are, they are
(缩略式 I'm, you're, he's, we're, you're, they're),
(否定缩略式 I'm not, isn't, aren't),
过去时 I was, you were, he was, we were, you were, they were
(过去时否定缩略式 wasn't, weren't),
过去分词been,现在分词being
英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。
“Be”除了原形的“be”之外,还有另外七种形式:
am, is, are, been, being, was, were.
在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)- 系动词Be(am, is, are )的用法:
一、口诀:
我用am,你用are,is连着他,她,它;
单数名词用is,复数名词全用are;
变疑问,往前提,句末问号某丢弃;
变否定,更容易,be后莫忘记;
疑问否定任你变,句首大写莫迟疑。
二、Be动词在一般过去时中的变化:
1、am和is在一般过去时中变为was;
2、are在一般过去时中变为were
3、带有was或were的句子,其否定、疑问的变化和am is are一样,即否定句在was或were后加 not,一般疑问句把was或were调到句首。
考点名称:否定句
- 否定句:
表示否定的句子。必须有否定词。
否定句的构成形式:
a. 谓语为be动词时,“be+not "一名学生。
b. 谓语为实义动词而且没有情态动词和助动词时,“do/ does/ did+not"构成否定。
例:I do not like dancing. 我不喜欢跳舞。
He does not want to go to school. 他不想去上学。
c. 谓语为“情态动词+实义动词”时,“情态动词+not”构成否定。
例:You must not smoke. 你千万不要吸烟。
I can not catch it. 我抓不住它。 - 否定句在英语语法中可以分为九类:
(1)一般否定句
I don't know this. No news is good news.
There is no person(smoking)/not a person/not any person(smoking)in the house.
(2)特指否定
He went to his office, not to see him.
I am sorry for not coming on time.
I don't think/believe/suppose/feel/imagine you are right.
(3)部分否定
All the answers are not right
All is not gold that glitters
I don't know all of them.
I can't see everybody/everything.
Both of them are not right.
(4)全体否定
None of my friends smoke.
I can see nothing/nobody.
Neither of them is right.
Nothing can be so simple as this.
(5)延续否定
You didn't see him, neither/nor did I.
You don't know, I don't know either.
He doesn't know English, let alone/to say nothing of/not to speak of(更不用说)French.
(6)半否定句
We seldom/hardly/scarcely/barely hear such fine singing.
I know little English. I saw few people.
(7)双重否定
You can't make something out of nothing.
What's done cannot be undone.
There is no sweet without sweat.
No gain without pains.
I can't help /keep/ laughing whenever I hear it.
No man is so old but(that)he can learn.
(8)排除否定
Everyone is ready except you.
He did nothing but play.
But for your help, I couldn't do it.
(9)加强否定
I won't do it at all.
I can't see it any more.
He is no longer a boy. 否定转移的形式与用法:
一、动词的否定转移
1.形式上否定主句的谓语,实际上是否定从句的谓语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”的主语是第一人称,谓语动词为没有任何副词修饰的一般现在时,它们的否定式实际上是对宾语从句的否定。
