你把例句打出來追問,我給你詳解.Is this coat_____?A she wanted forbirthdaypresentB which she wanted for birthday presentC one she wanted for birthday presentD the one she wanted for birthday presentD還有一個例句呢？對的。我一開始選b。把他看成 this is coat +定語從句。有什么區(qū)別，怎么區(qū)分。您細講一下。謝謝this is coat怎么可能會有這種說法呢？要不就是this is a coat要不就是this is the coat總之缺少了冠詞。還有一個例句，我繼續(xù)給你講解。This is the coat (that/which) she wanted for birthday present.=This coat is the one (that/which)she wanted for birthday present.區(qū)分就是冠詞的問題。題目改為Is this the coat_____?就選AB。
