5. “Have you seen _____ pen? I left it here this morning.” “Is it _____ black one? I think I saw it somewhere.”

A. a, the                                                   B. the, the

C. a, a                                                      D. the, a

【陷阱】誤選A，生搬硬套冠詞用法規則：第一次提到某人或某事物用不定冠詞，第二次再提到該人或該事物時用定冠詞。

【分析】最佳答案為C。第一空填a，比較好理解；而第二空填a是因為此句中的one 并非指前面提到的 pen，即這里的 one 與前面的 pen 并非同一事物，這從后面一句的 I think I saw it somewhere 可以清楚地知道。請比較下面一題：

“Have you seen _____ pen? I left it here this morning.” “Is it _____ black one? I found it in the corner.”

A. a, the                                                   B. the, the

C. a, a                                                      D. the, a

此題的最佳答案是 A不是C。請注意其后 I found it in the corner這一信息，它表明說明者是拿著筆在與對方說話。請再看一個類似的例子：

“Have you seen _______ new bike? I put it here just now.” “Is it _______ white one? A boy has ridden it away.”

A. a; a                                                      B. a; the

C. the; the                                                D. the; a

此題答案選A，注意其后的 A boy has ridden it away 表明自行車已不在說話者身旁。

6. My friend Mary is _____ beautiful girl and _____ girl everyone likes to work with.

A. a, a                                                      B. a, the

C. the, a                                                   D. the, the

【陷阱】很容易誤選B，認為第一次提到 girl 用不定冠詞，第二次提到就應該用定冠詞。

【分析】最佳答案為A。句中第二次提到 girl 時并不是特指的，此句實為一省略句，補充完整為 My friend Mary is a beautiful girl and she is a girl everyone likes to work with. 請再做以下試題(答案選A)：

(1) Jim is _______ brave boy and _______ boy never fearing anything.

A. a, a                                                      B. a, the

C. the, a                                                   D. the, the
