45、建了一些新工厂。【误区警示误区警示】（1）“get+及物动词的过去分词”表被动。指主语遭遇变化或不好的事件。He got caught in the rain last night.他昨晚被雨淋了。（2）动词带有双宾语时，可把其中的一个宾语变为主语，另一个宾语仍然保留在谓语后面，变为被动句主语的通常是间接宾语。His mother gave him a present for his birthday.他妈妈送给他一件生日礼物。He was given a present by his mother for his birthday.（也可改为A present was given to hi

46、m by his mother for his birthday.）（3）当“动词+宾语+宾语补足语”结构变为被动结构时，将宾语变为被动结构中的主语，其余不动。The manager found a cook smoking in the canteen and fired him on the spot.经理发现一个厨师在食堂抽烟，当场解雇了他。=A cook was found smoking in the canteen by the manager and was fired on the spot.一个厨师被经理发现在食堂抽烟，当场被解雇了。应该是变为“被动句的主语”（4）在使役动词

48、f by Grandma when my parents went out to work.我父母出去工作时，我妹妹由奶奶照顾。（6）“It+be+及物动词的过去分词+that 从句/to do sth.”是固定句型。Since it is believed that strong smells can affect the senses，volunteers are required not to eat or drink for eight hours before the experiment.因为人们相信强烈的气味会影响感官，所以志愿者们被要求在实验前八小时内不能进食或饮水。完成句子完
