2.1 be动词的一般现在时
be动词是系动词的一种,表示&&&是&&&的意思。现在式(The Present Forms)有am,is,are三种。这三种动词的原形是be,所以它们称为be动词。
2.1.1 be动词的现在式
be动词的现在式有am,is,are三种,分别接在不同人称的主语之后:
2.1.2 be动词句型的构成
肯定句:主语 + be动词(am/is/are)...
否定句:主语 + be动词(am/is/are) + not...
疑问句:be动词(am/is/are) + 主语...?
疑问代词/疑问副词 + be动词(am/is/are) + 主语...?
2.1.3 be动词的肯定句
句型:主语 + be动词...
be动词的肯定句由&主语 + be动词(am/is/are) + 表语&构成:
I am a doctor.我是一名医生。
Mary is at work.玛丽在工作。
He is very brilliant.他非常聪明。
It is a nice day.今天天气晴朗。
You are my only friend.你是我惟一的朋友。
They are students.他们是学生。
2.1.4 be动词的否定句
句型:主语 + be动词(am/is/are) + not...
be动词一般现在时的否定句结构,是在be动词am,is,are之后加not:
We aren't her classmates.我们不是她的同班同学。
I'm not Tom.我不是汤姆。(I'm是I am的缩写,读作/aim/。)
It's not a cat,but a dog.这不是猫,而是狗。
Things are not always what they seem(to be).事物并不总是与表象一致。
be动词否定句的缩写方式:
is not的缩写是isn't,读作/&iznt/;are not的缩写是aren't,读作/a:nt/;I am~的否定句是I am not~,缩写为I'm not~;am not不缩写在一起。
2.1.5 be动词的一般疑问句
句型:be动词 + 主语...?
回答方式:Yes,主语 + be动词(am/is/are)...
No,主语 + be动词(am/is/are) + not...
be动词的一般疑问句是将be动词置于主语之前(大写am/is/are的第一个字母),在句尾加问号;这种语序是主语和谓语倒装语序:
肯定句:They are fruit.它们是水果。
疑问句:Are they fruit? 它们是水果吗? (主语和谓语倒装)
肯定句:The book is on the table.书在桌子上。(主语和谓语倒装)
疑问句:Is the book on the table? 书是在桌子上吗?
回答由be动词构成的疑问句时,肯定要用Yes,否定用No:
Are you John's brother? &Yes,I am.你是约翰的兄弟吗? &&是的,我是。
Are Mary and John still at school? &No,they are not.玛丽和约翰仍在学校吗? &&不,不在了。
Are you there? 喂,你听着吗? (打电话时用)
【注意】 Yes或No的后面一定要加逗号,其后的主语小写,I(我)除外。I永远大写。在回答句子时,主语必须是代词。
2.1.6 be动词的特殊疑问句
句型:疑问代词(主语) + be动词(am/is/are)...?
疑问代词/疑问副词 + be动词(am/is/are) + 主语...?
用who和how等疑问代词或疑问副词与be动词构成的疑问句称为特殊疑问句。就主语提问时,如果主语是疑问代词或是带有疑问限定词的名词词组,如What number is...? (什么数字是&&? ),Which boy likes...? (哪个男孩喜欢&&? ),Whose car is...? (谁的车是&&? )等,将疑问代词或带有疑问限定词的名词词组置于be动词之前(am,is,are的第一个字母无需大写),在句尾加问号;这种语序是陈述句语序。就表语提问时,则以一个疑问代词或疑问副词开头,之后是&be动词 + 主语...&(am,is,are的第一个字母无需大写),在句尾加问号;这种语序是主语和谓语倒装语序。be动词的特殊疑问句不能用Yes或No来回答:
Who is there? 谁在那里? (就主语提问)
Who is she? &She is my mother.她是谁? &&她是我母亲。(就表语提问)
Who are they? &They are John&s classmates.他们是谁? &&他们是约翰的同学。
what(指某一或某种未知的事物或人)&什么&:
What are these? &These are books.这些是什么? &&这些是书。
What are they? &They are sailors.他们是干什么的? &&他们是海员。
What is Susan like? 苏珊是什么样的人? /苏珊的人品如何? (就介词宾语提问)
whose&谁的&:

Whose are these shoes? &They are Tom's.这些是谁的鞋子? &&是汤姆的鞋子。
which&哪一个、哪一些&:

Which is heavier,iron or copper? 铁和铜,哪一个更重?
where&在哪里&:

How old is your son now? &He is fifteen.你儿子多大年纪了? &&他15岁了。

2.1.7 There is/are的用法
There is/are用于表示某物或某人的存在。
1.There is/are...的肯定句
句型:There is/are + 单数/复数名词 + 表示地点/场所的词或短语:

引导词 真正的主语 地点状语
There be结构为倒装句,真正的主语是There is/are后的名词,如上述例句。详见第25章倒装25.1完全倒装。有的辞典将There be结构中的There列为代词,作be的主语(参见《郎文当代高级英语辞典》)。
2.There is/are的否定句
句型:There is/are + not...
There is/are的否定句是在is/are后面加not:
There isn't going to be a party tonight.今晚没有聚会。
There aren't any cakes left.没有一点蛋糕剩下来。
3.There is/are的疑问句
一般疑问句句型:Is/Are there...?
There is/are的一般疑问句是将is/are调到there前面,大写is/are的第一个字母:
Is there anything you want to tell me? 你有什么事情想告诉我吗?
Are there enough tools to go round? 工具够大家用吗?
特殊疑问句句型:疑问副词 + 形容词 + 名词 + is/are + there...? There is/are~的特殊疑问句是以&疑问副词 + 形容词 + 名词等&开头,之后是&is/are + there? &:
How much are there? 有多少?
How many rooms are there in each flat? 每套房子里有多少个房间?
How many students are there in your class? 你班上有多少名学生?
【注意】 There be结构中的谓语有时不用动词be,而用seem,appear等:
There appeared to be no one who could answer our inquiries.似乎没有人能回答我们的询问。
There appears to have been a nasty accident.似乎发生了一起严重事故。
There seems(to be)no doubt about it.此事似乎无可置疑。
There don't seem to be any missing.好像没有什么丢失了。
2.1.8 Here的句型
句型:Here is/are + 名词.

Here is the book you want.你要的书在这里。
Here is the pound I owe you.这是我欠你的英镑。
Here they/we are! 他们/我们终于到了!(代词之后)

此句型还可用于引起对某物或某人注意:
Here comes the manager.经理来了。
Here he comes.他来了。您的举报已经提交成功,我们将尽快处理,谢谢!
是复数,所以是DO
