語(yǔ)法拓展
一、where引導(dǎo)的特殊疑問(wèn)句
1.用法：該特殊疑問(wèn)句用來(lái)詢問(wèn)人或物所在的位置，其結(jié)構(gòu)為“where is +單數(shù)名詞？”或“where are+復(fù)數(shù)名詞？”。也就是說(shuō)where后面be動(dòng)詞是用is還是are取決于be動(dòng)詞后面的名詞或代詞的單復(fù)數(shù)。單數(shù)用is,復(fù)數(shù)用are。
Where’s my hat?
Where are your parents?
2.答語(yǔ)：where引導(dǎo)的特殊疑問(wèn)句答語(yǔ)有以下三種形式。
（1）用It’s+介詞短語(yǔ)（對(duì)應(yīng)Where is...?）或They’re+介詞短語(yǔ)（對(duì)應(yīng)Where are...?）。
—Where’s my hat?
—It’s on your head?
（2）可直接回答物品所在地點(diǎn)，省略it’s或they’re。
—Where are your parents?
—(They are) In the room.
（3）當(dāng)你不知道在哪里，可用“I don’t know”來(lái)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(dòng)詞，當(dāng)主語(yǔ)為第三人稱單數(shù)時(shí)，助動(dòng)詞應(yīng)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(nèi)”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(diǎn)、在某年、月、世紀(jì)、早上、晚上等及使用什么語(yǔ)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(shí)間（后接具體某一天）。如：on Monday在星期一
3.under意為“在……下面”。
如：under the desk在課桌下
