1、Unit 4 Wheres my schoolbag?第三课时 Section A(Grammar Focus3c)单元语法精讲一、where的用法where是疑问副词,意为“(在)哪里；(在)什么地方”,用来对表示地点的副词或介词短语进行提问。由where等疑问词引导的疑问句叫作特殊疑问句。句型“Where is/are+主语(人或物)?”用来对地点进行提问。其中is后接单数意义的主语,are后接复数意义的主语。eg：Where are your books?你的书在哪里?回答时,用句型“主语+is/are+表示地点的介词短语”。主语一般用it,he,she或they来代替句中的单复数主语。
2、eg：Where is your sister?你姐姐(妹妹)在哪里?She is in the room.她在房间里。【注意】where is可缩写成wheres,但where are则不能缩写。二、方位介词：on,in,under介词on在表示地点时,意为“在上面”,指某人或某物在另一物体上面(表面接触,上下紧贴)。in表示地点时,意为“在里面(内部)”。under表示“在下面”,与on互为反义词。eg：on the desk在课桌上面in the bedroom在卧室里under the bed在床下面单元语法强化训练一、根据图片提示完成对话。每空一词。1.A:Where the des
