含有 be 动词的一般疑问句
1. 结构:
2. 回答:
肯定回答：Yes, 主语(人称代词主格) +be (am/ is/ are). ，主语和 be 动词不能缩写。
否定回答:No, 主语(人称代词主格)+be(am/ is/ are) +not. ，且 be 和 not 常用缩写形式，但 am 和 not不能缩写。
—Is this your pen 这是你的钢笔吗
—Yes, it is. 是的，它是。 / No, it isn’t. 不，它不是。
Be 动词(am/ is/ are)+主语+其他
【注意】答语中主语只能用问句中主语所对应的人称代词主格充当。
—Is Jim your brother Jim 是你的哥哥吗
—Yes, he is. 是的，他是。 (画线部分不能用 Jim)
3. 含有 be 动词的陈述句变一般疑问句: （一提二变三问号）
将 be 动词提前，将人称进行相应变换并把陈述句中的句号改成问号。
如果原主语为第一人称，则应把第一人称变为第二人称，be 动词也要作出相应的变化；如果有形容词性物主代词 my 或 our，也应改为 your。
I am Lucy. 我是Lucy。
This is my key. 这是我的钥匙。
→Are you Lucy 你是Lucy 吗
→Is this your key 这是你的钥匙吗

2. 名词性物主代词与形容词性物主代词的异同:
(1)两者都是物主代词，表示物品的所属关系;
(2)形容词性物主代词相当于形容词，一般放在名词之前作定语。
my pencil 我的铅笔；his schoolbag 他的书包
(3)名词性物主代词相当于“形容词性物主代词+名词”，因此不能用于名词前。
This is my book. = This book is mine. 这是我的书。
—Where is your eraser 你的橡皮在哪里
—Mine is in my pencil box. 我的 橡皮在铅笔盒里。
