(2) 学习指示代词, 应注意以下几点:
①this与is, these与are没有缩写形式。
e.g. This is a Chinese car. 这是一辆国产轿车。
②指示代词作主语指物并用于问句中 时, 回答一般用it代替this和that，they代替these和those。
e.g. —Is that a ruler？ 那是尺子吗？
—No, it isn’t. It’s a pen. 不, 不是。是钢笔。
—Are these your books 这些是你的书吗
—Yes, they are. 是的，它们是。

Grammar
1. 含有be（am, is, are）动词的一般疑问句的结构及其回答
一般疑问句 Be （Am/Is/Are）+主语+其他？
肯定回答 Yes, 主语+be（am/is/are）.
否定回答 No, 主语+be（am/is/are）+not.
①肯定回答中的be动词不能与主语缩写；否定回答中的be可以与主语连在一起，用缩略形式，也可与not连在一起，not用缩略形式，但am 不能与not缩写。
②如果一般疑问句的主语不是人称代词，回答时应用相应的人称代词替换。
e.g. —Is your hat blue 你的帽子是蓝色的吗？
—No, it isn’t/it’s not. 不，它不是。

2. 含有be动词的一般疑问句的语调
朗读一般疑问句用升调，其简略答语用降调。
e.g. —Is that your pen 那是你的钢笔吗？（升调）
—Yes, it is. 是的，它是。（降调）
3. 含有be动词的陈述句变为一般疑问句
be动词提到句首，首字母要大写，句末用问号。如果原来句中的主语为I，变为一般疑问句时要改为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；反之亦然。
e.g. I am a student. 改为一般疑问句
This is my brother. 改为一般疑问句
Is this your brother
Are you a student
This is a pencil.
Is this a pencil
That is my pencil.
Is that your pencil
These are his pencils.
Are these his pencils
Those are Anna’s books.
Are those Anna’s books
Practice
将下列句子改为一般疑问句
巧学妙记
物主代词分两家，形、名词性各一霸
his，its无变化，my，mine记牢它
其余变形规律化，形容词性后加尾巴（-s）
Grammar
三、名词性物主代词
三、名词性物主代词
（1）在句中独立使用，相当于“形容词性物主代词+名词”，故其后不能接名词。
e.g. Here are two pens. The black one is yours（=your pen） and the red one is mine（=my pen）.
这儿有两支钢笔。黑色的是你的，红色的是我的。
（2）在句中可作主语、宾语、表语等。作主语时，谓语动词的单复数由名词性物主代词所指代的名词的数而定。
e.g. This is my dictionary. His（=His dictionary） is on the desk.
这是我的字典。他的在书桌上。
—Are these his books 这些是他的书吗？
—No, his（=his books） are in the schoolbag. 不，他的书在书包里。
