Language points1.pencil box文具盒pencil box=pencil case注意：box的復(fù)數(shù)形式是boxes。2.eraser 橡皮；鉛筆擦；黑板擦The eraser is white.eraser是以元音音素開頭的單詞，前面的不定冠詞用an。如：an eraser一塊橡皮 3.Is that your schoolbag?那是你的書包嗎？ No,it isnt.Its his.不，不是。那是他的。（教材第11頁）（1）Is this/that.?這/那是嗎？這種句型也是含有be動(dòng)詞的一般疑問句，讀時(shí)讀成升調(diào)，句尾用問號(hào)。注意：由指示代詞this,that作主語的一般疑問句，作答時(shí)，常用it代替this或that,以避免重復(fù)。Is this your pencil?正：Yes,it is./No,it isnt.誤：Yes,this is/No,this isnt. （2）his在這里是作名詞性物主代詞使用，并不是作為形容詞性物主代詞，意為“他的書包”，相當(dāng)于his schoolbag。【拓展】形容詞性物主代詞不能單獨(dú)使用，后面必須接名詞；而名詞性物主代詞可以單獨(dú)使用，后面不能接名詞。4.Are these your books?這些是你的書嗎？ No,they arent.Theyre hers.不，不是。它們是她的。（教材第13頁）her pron.她的。該詞為名詞性物主代詞，在句中作表語，此外還可作主語。而her為形容詞性物主代詞，在句中作定語。 Exercise一、單項(xiàng)選擇。1.There are two_on the desk.
