题目内容

With the development of science, more new technology to the field of IT.

A．has introduced B．is being introduced

C．is introduced D．was introduced

【答案】

【解析】

试题分析：句意，随着科技的发展，更多新的技术被引进到IT领域。表示现阶段正在进行的动作，用现在进行时。且主语new technology与动作introduce之间是被动关系，用现在分词的被动语态，故选B。

考点：时态和语态考查题

点评：动词是谓语动所表示的动作或情况发生时间的各种形式。英语动词有16种时态，但是常用的只有9种：一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时、现在完成进行时。当句子的主语是动作的执行者时，谓语的形式叫主动语态。句子的主语是动作承受者时，谓语的形式叫被动作语态。被动语态由助动词be + 过去分词构成，时态通过be 表现出来。
