語法拓展
一、where引導的特殊疑問句
1.用法：該特殊疑問句用來詢問人或物所在的位置，其結構為“where is +單數名詞？”或“where are+復數名詞？”。也就是說where后面be動詞是用is還是are取決于be動詞后面的名詞或代詞的單復數。單數用is,復數用are。
Where’s my hat?
Where are your parents?
2.答語：where引導的特殊疑問句答語有以下三種形式。
（1）用It’s+介詞短語（對應Where is...?）或They’re+介詞短語（對應Where are...?）。
—Where’s my hat?
—It’s on your head?
（2）可直接回答物品所在地點，省略it’s或they’re。
—Where are your parents?
—(They are) In the room.
（3）當你不知道在哪里，可用“I don’t know”來回答，意為“我不知道”。
—Where’s my bag?
—I don’t know.
注意：don’t=do not,其中do是助動詞，當主語為第三人稱單數時，助動詞應用does,與not縮寫為doesn’t。
She doesn’t know.
二、介詞in,on與under的用法
1.in意為“在……里面，在……內”通常表示在某一空間里。
My ring is in the bag.
【拓展】in還可以表示地點、在某年、月、世紀、早上、晚上等及使用什么語言。
如：in Wuhan；in the morning；in 2014；in English
2.on意為“在……上面”，表示物體間有面的直接接觸。
A cup is on the desk.
【拓展】on也可表示時間（后接具體某一天）。如：on Monday在星期一
