【題目】English is ________ useful subject. No one should give it up.

A. a B. an C. the D. 不填

【答案】A

【解析】句意:英語(yǔ)是一門(mén)有用的學(xué)科,誰(shuí)也不應(yīng)該放棄它。aan都是不定冠詞,修飾可數(shù)名詞單數(shù),表示泛指一個(gè)…;an用于元音發(fā)音開(kāi)頭的單詞前;the是定冠詞,表示特指?蘸subject是可數(shù)名詞的單數(shù)形式,這里表示一門(mén)學(xué)科,故用不定冠詞修飾。useful是輔音/j/開(kāi)頭的,故應(yīng)選A。
