英语语法变形将下列句子变成"v+ing" . 1.After we stood in the queue for hours, we got twotickets. 2.After they finished their homework, the boys went home. 3.He always consults others before he does anything.
“after + 句子” 可以省去主语和助动词(如果存在),改写为 after doing sth.改写时要注意两点:
1)主句的主语是否与从句一致,如果一致就用现在分词,如果不一致就需要改为过去分词 done 或者变为分词的复合结构 one's doing.后者如下:
* After they gave him something,he went away.(主句主语与从句的谓语动词成动宾关系)—— After given something,he went away.
* After they came back,he went away.(主句主语与从句谓语动词没有逻辑关系)—— After their coming back,he went away.
2) 分析主从句谓语动词的时间关系,如果主从句行为同时或先后发生则用分词的一般形式 doing,如果从句行为发生在主句行为之前则用完成形式 having done.
基于上述分析,下列句子分别可以改写为:
1.After we stood in the queue for hours,we got two tickets.
-- After having stood in the queue for hours,we got two tickets.
2.After they finished their homework,the boys went home.
-- After finishing their homework,the boys went home
3.He always consults others before he does anything.
-- He always consults others before doing anything.
