《Where's my schoolbag?》PPT課件11
1．方位介詞on，in，under的用法
on，in，under三者都是方位介詞，后跟名詞或代詞構成介詞短語(yǔ)，表示所處的不同位置。
(1)on“在……上”，指一物體在另一物體的表面上。
(2)in“在……里面”，指一物體在另一物體的內部。
(3)under“在……下”，指一物體在另一物體的正下方，兩物體不接觸。
表示某物或某人在某方位時(shí)，常用句型為：主語(yǔ)(人或物)＋am/is/are＋介詞短語(yǔ)(表地點(diǎn))。
2．Where's my schoolbag？我的書(shū)包在哪？
這是由where放在句首引導的特殊疑問(wèn)句。where是特殊疑問(wèn)詞，意為“在哪兒，在哪里”，用來(lái)詢(xún)問(wèn)某人或某物所在的位置。句型結構為：Where＋is/are＋主語(yǔ)(人或物)？意為“某人或某物在哪兒？”回答時(shí)不用yes或no，應用句型：主語(yǔ)＋is/are＋表示地點(diǎn)的介詞短語(yǔ)。主語(yǔ)一般用it(he，she)或they來(lái)代替問(wèn)句中的單數或復數主語(yǔ)。
