Language points
一、含有be动词的一般疑问句
1. 一般疑问句是用来询问某件事情或某种情况是否属实,并用yes或no作出肯定或否定回答的疑问句。
2. 含有be动词的一般疑问句的结构及其回答:
结 构 Be动词(Am/Is/Are) +主语+其他?
肯定回答 Yes, 主语(人称代词) +be动词(am/is/are).
否定回答 No, 主语(人称代词) +be动词(am/is/are) +not.
①作否定回答时,通常is,are与not缩写,am和not不能缩写。
--Is he mike 他是迈克吗? --No, he isn’t. 不,他不是。
--Are you Tom 你是汤姆吗? --No, I’m not. 不,我不是。
②一般疑问句中的主语为this/that时,答语中的主语要用it,代替this/that。
--Is this/ that your pen 这/那是你的钢笔吗?
--Yes, it is. 是的,它是。 /No, it isn’t. 不,它不是。
③一般疑问句中的主语为these/those时,答语中的主语要用they,代替these/those。
--Are these/those your books 这/那些是你的书吗?
--Yes, they are. 是的,它们是。
/No, they aren’t. 不,他们不是。
3. 将含有be动词(am, is, are)的陈书记转换为一般疑问句的规则。
①将be动词提到句首,注意首字母要大写。
This is his schoolbag. (改为一般疑问句)
Is this his schoolbag
This is my ruler. (改为一般疑问句)
Is this your ruler
I am a student. (改为一般疑问句)
Are you a student
②如果陈述句主语是第一人称或者含有第一人称的物主代词,在一般疑问句中需要改为对应的第二人称的人称代词或者物主代词。
1. 名词性物主代词的形式
二、名词性物主代词
人 称 数 人称代词 形容词性物主代词 名词性物主代词
第 一 人 称 单数 I my mine
复数 we our ours
第 二 人 称 单数 you your (你的) yours
复数 you your (你们的) yours
第 三 人 称 单数 he his his
she her hers
it its its
复数 they their theirs
2. 名词性物主代词的用法
①相当于“形容词性物主代词+名词”,其后不能再接名词。
This is my pen. His is over there. 这是我的钢笔,他的在那边。
②在句中作主语、宾语或表语。作主语时,谓语动词的数应由所指代的名词的数来决定。
That is my ruler. Hers is in her bag. 那是我的直尺。她的在她的包里。
=Her ruler
These are my keys. Yours are in the bag. 这些是我的钥匙。你的在包里。
=Your keys
