重点语法
(一)含有be动词的确认物品所属关系的一般疑问句
一般疑问句是用来询问事物或某种情况是否属实，需要对方作出肯定或否定回答的句子。目前所学到的一般疑问句构成是“Be(Am, Is, Are)＋主语＋其他？”
1.以 is开头的一般疑问句，答语为“Yes, it/he/she is.”或“No, it/he/she isn’t. ”。

Is that his/her... Yes, it is./No, it isn’t.
Is she... Yes, she is./No, she isn’t.
Is he... Yes, he is./No, he isn’t.
【易错点】
在回答 Is this/that... 句型时，用 it代替 this/that。
肯定回答 Yes,it is(不能缩写为it’s).
否定回答 No,it isn’t.
Exercise:
—Is this your eraser
—Yes, .
this is B．this’s C．It’s D．it is
key:D

Are they your/his/her... Yes, they are./No, they aren’t.
