Ⅰ--第9小題
Mike was elected __/__ captain of the team.
---分析---：按照我們上面“不用冠詞的場合”講的，在表示獨一無二頭銜、職務的名詞作補語時，其前不用冠詞，所以captain前什么也不填。（書上答案錯誤）
Ⅰ--第15小題
The play, Hamlet, attracted a large audience.
---分析---：首先，第一個空特指Hamlet這部劇，無疑應該填定冠詞the。這里主要是audience前的第二個空，audience 本身是一個集體名詞，可數。分析這樣的詞時，我們要看它強調的是整體還是整體中的每一個個體，如：
My family is a large one. (把family 看作了一個整體)
My family were listening to the tape. (強調的是family中的每一個成員)
本題中audience 強調的是“一大群觀眾”這樣一個整體概念，所以應該填a。
Ⅰ--第22小題
