ask sb to do sth和ask sb doing sth

ask sb. to do sth. 是正确用法。

1、并没有ask sb. doing sth.这个说法, 请求别人做的事情是未发生的,不能用进行时。

2、让某人做某事句型还有: make sb. do sth. ；let sb. do sth.；have sb. do sth；get sb. to do sth. 等。

3、接双宾语句型：Subject(主语)+Verb(谓语)+ Indirect object(间接宾语)+Direct object (直接宾语)

例: My father bought me a present.

3、It is not in reason to ask him to do such a job.

区别就是

是要去做
有个趋势
doing是正在做
或者是个过程
就好像regret

®ret
doing.
regret
doing对做过的事表示遗憾、后悔
regret
to
do对要做的事遗憾
