Step Ⅲ Acquire the Rules 2

T: Good. Then why do we use past participle instead of other forms? For example, can we use –ing form here? Ss: No. 因为句子主语跟分词动作之间是被动的逻辑关系。

T: Yes, but there are also other forms of participles that can be used as adverbial. 1. Show the following sentences on PPT: Seen from the top of the hill, the school is beautiful. Seeing from the top of the hill, we can see the school clearly. Having eaten his dinner, the boy rushed out. Having been criticized by the teacher, the boy gave up smoking. T: Now, look at your handouts.Work in groups to discuss the difference and finish the form. Three students in a group and two minutes for you. Hurry up!

2. A while later, ask one volunteer to write the answer on the blackboard. Check the answer and show the tips: 主动/被动

主动

doing having done done having been done 形式

与主句谓语先后

几乎同时发生

先于主句谓语发生

--------- 先于主句谓语发生

被动

归纳口诀：

分词作状语，主语是关键。

前后两动作，主语是一致。

找出主语后，关系自然明。

主动就用-ing，被动就用-ed。

having done表在前，而且是主动。

having been done 也在前，而且是被动。
