關(guān)閉窗口 陷阱3 誤解名詞性物主代詞的單復(fù)數(shù)意義
名詞性物主代詞mine, yours, his, hers, its, ours, theirs等作主語時(shí)，謂語動(dòng)詞的數(shù)取決于該動(dòng)詞后面名詞的數(shù)，即動(dòng)詞后面的名詞是單數(shù)形式，謂語動(dòng)詞用單數(shù)形式；動(dòng)詞后面名詞為復(fù)數(shù)形式，謂語動(dòng)詞用復(fù)數(shù)形式。如：
His is a new bike. 他的是一輛舊自行車。
Ours are old bikes. 我們的是些新自行車。
陷阱4 誤解某些不定代詞的單復(fù)數(shù)意義
有些不定代詞，如all, some, none, most, any等，當(dāng)它們用作主語時(shí)，若指復(fù)數(shù)概念，謂語動(dòng)詞用復(fù)數(shù)形式；若指單數(shù)概念，則謂語動(dòng)詞用單數(shù)形式。如：
Not all work is difficult. 不是所有的工作都難。
Not all the students are here. 不是所有的學(xué)生都在這兒。
