— What’s this in English?

— It’s _____ eraser.

A．a(chǎn)                B．a(chǎn)n               C．the              D．/

 

【答案】

B

【解析】

試題分析：eraser是以元音音素開頭的單詞，故其前面需要冠詞時(shí)要用an，故選B。

考點(diǎn)：不定冠詞的用法。

點(diǎn)評(píng)：不定冠詞有兩個(gè).根據(jù)后接單詞詞首音素的不同采用不同的形式.當(dāng)詞首音素為元音時(shí),用an;當(dāng)詞首音素為輔音時(shí),用a.實(shí)際中也可以根據(jù)首字母來判斷,這在大多數(shù)情況下不會(huì)出錯(cuò),但是個(gè)別單詞需要注意,如:hour,小時(shí)。名詞前已有作定語的this、that、my、your、some、any、等限定詞時(shí)不用任何冠詞，也就是零冠詞。
