the little dog is playing the cat ,为什麽唔playing葽改为playing with
it is raining outside.you must take an umbrella 为什麽不用rainy用raining？
taking an umbrella is good for you on a rainy day为什麽不用take用taking？
答
1)play with是固定语法
play with意思是跟什么一起玩
2)rainy是形容词,意思是下雨的,有雨的.
这句意思是:外边正在下雨,你必须带上一把伞.正在下雨,所以用raining.
3）taking an umbrella做主语 因为TAKE在句首,又属于意动状况,因此用taking,这些问题比较基础
