Question

i suddenly heard an elephant crying as though ___。

looking down ，i immediately recognised that something was wrong and ran down to the edge of the near bank A fightB a fright C frightened D frighting 解释。原因知识点。

Answer 1

C

解析：其实as though 后面省略了主语和部分谓语，补全后：

i suddenly heard an elephant crying as though 【it was frightened】

翻译：我突然听见一直大象在嚎叫仿佛受到了惊吓，受到惊吓是被动，因此使用被动语态。

如果条件状语从句的主语是it +be动词，则可以省略。

如有疑问，请追问。

无疑后请采纳。
