2020年人教版七年级（上）英语第6讲：unit 3 语法篇-教师版和学生版

Unit3语法篇 一、含有be动词的一般疑问句 1. 将含有be动词的陈述句转换为一般疑问句 将be动词提到句首，首字母大写，句末用问号，句子就变成了一般疑问句。 如果原来句中的主语是I，变为一般疑问句要改为you；原来句中有形容词性物主代词my，变为一般疑问句时要改为your。 I am Zhang Yang. → Are you Zhang Yang? That is my bike. → Is that your bike? 2. 含有be动词的一般疑问句的肯定回答和否定回答 肯定回答：Yes, 主语+be（am, is, are）. 否定回答：No, 主语+be（am, is, are）not. 3. Is this/that…?结构的一般疑问句的答语要用Yes, it is.或No, it isn't.而不用Yes, this/that is.或No, this/that isn't。 另外，Are these/those …? 结构的一般疑问句的答语要用Yes, they are.或No, they aren't.而不用Yes, these/those are.或No, these/those aren't. —Is that your ruler? 那是你的尺子吗？ —Yes, it is./No, it isn't. 是的，它是。/不，它不是。 —Are those his dictionaries? 那些是他的词典吗？ —Yes, they are./No, they aren't. 是的，它们是。/不，它们不是。 二、名词性物主代词  1. 英语中的物主代词分为形容词性物主代词和名词性物主代词，其中名词性物主代词起名词的作用。 单复数 单数 复数 人称 第一人称 第二人称 第三人称 第一人称 第二人称 第三人称 名词性物 主代词 mine 我的 yours 你的 his 他的 hers 她的 its 它的 ours 我们的 yours 你们的 theirs 他/她/它们的 2. 名词性物主代词在句中独立使用，其后不接名词；名词性物主代词相当于“形容词性物主代词+名词”。 Look at the two pencils. The blue one is yours and the green one is mine. 看这两只铅笔，蓝色的是你的，绿色的是我的。 3. 名词性物主代词用作主语时，谓语动词的数应随所指者的数而定。   —Is this ruler yours or hers?   —It’s mine. Hers is in her bag.(Hers=her ruler)   —Whose books are these?   —They are his. Yours are over there.(Yours=Your books) 单项选择 1. This isn't pencil. is in my pencil box.
