问题补充：

—Hey, Jack. You on the phone just now. But you weren’t here and the man left a phone number.

—Oh? I was in the library.

A. wanted

B. are wanted

C. were wanted

D. have wanted

答案：

A. wanted

B. are wanted

(答案→)C. were wanted

D. have wanted

解析：句意：--- 嗨，杰克。刚才有人打给你电话。但你不在这里，那人留下一个电话号码。---哦？我当时是图书馆里。又由句意可知是被动语态，A、C是主动形式，所以排除，B. are wanted是一般现在时的被动，C. were wanted是一般过去时的被动。just now刚才，说明谓语动词用一般过去时，故选C。

考点: 考查动词时态和语态的用法。
