—May I have a look at the MP4,sir
—Which one _____black one
A.A B.An C.The D.不填
本句中特指“這臺黑色的”,所以用定冠詞the.
—Have you seen ____pen I left it on my desk this morming?
—Is it ____ green pen It was taken by Mr.Wang.
A.a;the B.the;the C.the;a D.an;an
從句意可以看出,問話人以為對方知道那支鋼筆,用定冠詞；而答話者則詢問是否是一只綠色的鋼筆,因此用不定冠詞.
這兩道題出自同一本練習(xí)里面.我覺得好矛盾,都是什么“黑色的”“綠色的”,為什么一個用定冠詞一個又用不定冠詞?
