3、bike./ Its his.是他的（自行車）。第一個(gè)his是形容詞性物主代詞，相當(dāng)于形容詞。置于名稱之前，用來修飾，限定名詞；第二個(gè)his等于his bike,是名詞性物主代詞，其后不加名詞。如：Our books are new.= The new books are ours.His bag is green.=The green bag is his.Their desks are all here.= The desk here are all theirs2Whose cat is that?那只貓是誰的？-It is her cat./Its hers.是她的（貓）。（1）who

8、s from Canada.這位男子來自加拿大。Man （男人）的復(fù)數(shù)形式是men; woman(女人)的復(fù)數(shù)形式是women,注意 women 的讀音是/wimin/.【拓展】當(dāng)man, woman 作定語修飾名詞時(shí)，如果名詞是復(fù)數(shù)，那么man 和 woman也用復(fù)數(shù)形式。如：men teachers 男教師， women doctors 女醫(yī)生6.Please help us find him.請幫我們找到他。（1）注意此句中動(dòng)詞help的句型。“幫助某人做某事”可以是help sb do sth,也可以是help sb to do sth.或 help sb with sth. 如：Sh
