这种情况下,句子中不带由by引起的短语。
The book is written for children. 这书是为孩子写的。
(2)当动作的承受者是谈话的中心时通常用被动语态。
这时可以带by短语。
This pen was given to me by Tom.这支笔是汤姆给我的。
(3)无必要或不愿说出动作的发出者。
这种情况通常是出于礼貌方面的考虑。
Smoking is not allowed here.这儿禁止吸烟。
2.怎样变主动语态为被动语态把主动语态变为被动语态,可分作三步进行:第一步:找出主动句的宾语,把它作为被动句的主语。
第二步:将谓语动词的主动语态变为被动语态(助动词be+及物动词的过去分词)。
变为被动语态时,时态不要变化。
第三步:将原主动语态的主语(若是人称代词,须变为宾格)放在介词by后边组成by短语,放到句子的后边。
如果我们没有必要说出动作的发出者,by短语则可以不要。
例如:(主动语态)His brother is often helped by him.(被动语态)【被动语态中考真题大练兵】1. —Would you please tell Miss Li that she as a volunteer for the 2008 Olympic Games?—Of course.
