help sb with sth 和help sb on sth有什么区别?怎么用?

help sb with sth 搀扶帮助某人做某事

help sb on sth 搀扶帮助某人穿衣服

help sb off sth 搀扶帮助某人脱衣服

1. I will help you with your housework.

2.I will help you on your new evening dress.

help sb. with sth.后接代词或名词,表达在某事上搀扶帮助某人.

我查阅字典,没有找到help sb. on sth.的用法,不外有help sb.(to) do sth.的用法.

help sb with sth

用某工具来搀扶帮助某人

help sb on sth

在某件事上搀扶帮助某人
