一、方位介词on, in与under的用法
1. 方位介词的用法：在英语中，当要表示人或物的位置时，通常要借助方位介词。方位介词不能单独使用，必须与其他词构成介词短语。
2. 方位介词on, in与under的用法
on
“在……上”，表示某人或某物在另一个物体的表面上，两者间有接触。
His pencil box is on the desk.
in
“在……里”，表示在某个空间内。
My books are in my schoolbag.
under
“在……下”，表示某人或某物在另一个人或物体的垂直下方，两者间不接触。
The dog is under the bed.
句型结构
答语
例句
Where is＋主语（单数）
He/She/It is
+介词短语.
— Where’s my hat
—It’s on the sofa.
Where are＋主语（复数）
They are
+介词短语.
— Where are the
desks and chairs
— They are in the
classroom.
二、where引导的特殊疑问句
where引导的特殊疑问句用来询问人或物所在的位置，其句型结构和答语如下：
(1) be动词要与主语的人称和数保持一致。
(2) where is可以缩写为where’s，但where are不
能缩写。
(3) 非正式场合中可省略主语和be动词，直接用
介词短语回答所在地点。
(4) 如果不知道某人或某物在什么地方，可用“Sorry,
I don’t know.”来回答。

— I don’t know. 我不知道。
*I know Tom’s telephone number.
我知道汤姆的电话号码。
*We know him very well. 我们对他非常熟悉。
【自主归纳】
(1) know为实义动词， 意为“知道； 了解”，可单独使用， 后面不跟人或物作宾语。I don’t know. 意为“我不知道。”其中don’t是do与not的缩写形式。
(2) know后也可跟作宾语的人或物。
【归纳拓展】谓语动词是实义动词的否定句
当谓语动词是实义动词时，其否定形式不是直接在动词后面加not，而是加助动词don’t或doesn’t （主语为第三人称单数时）来完成。
He doesn’t know my name.
他不知道我的名字。
I don’t know the boy. 我不认识这个男孩。
