Such animals as South China tigers are believed_______, for we’ve had no track of them for ages.

A

becoming extinct

having been extinct

答案解析

本题考查时态和believe的用法

C选项,当believe为被动语态时,后面习惯接不定式。根据后半句“for we’ve had no track of them for ages”判断,时态应为现在完成时。extinct“绝种的,灭绝的”。综上,C选项正确。

A选项,与题意不符,故排除。

B选项,与题意不符,故排除。

D选项,与题意不符,故排除。

故正确答案为C 项。
