The computer???????? in 1946 in America.

A. is invented????????????? ????????????? B. was invented????????????? C. invents????????????? ????????????? D. invented

 

【答案】

B

【解析】

试题分析:句意:电脑是1946年在美国被发明的。根据句意可知这是一件过去的事情了,而且句子的主语computer invent 之间构成被动的关系,故应使用被动语态。一般过去时的被动语态应是was/were + 过去分词。故选BA选项是一般现在时的被动语态;C是一般现在时,D是一般过去时,两项没有用被动语态。

考点:考查动词。
