1. playing , (enjoy doing sth. 喜欢做某事)
2. laughing , (laugh at , 因...而发笑,laugh 这里是动词, 因为前面有your,需要变成动名词形式 )
3. working, ( mind doing sth. 介意做某事. )
4. writing, painting, ( try to do sth. 和try doing sth都存在,但是意思不同,try to do sth是未做而想试着去做,try to do sth是行动起来了,这里有he failed, 证明已经试着做了,所以用try doing sth.)
5. coming, (come 本身是动词, 加ing变成名词形式,又称为动名词)
6. saving (介词后面都加V-ing 形式,譬如 : of + doing,for+ doing, at + doing,in+doing 等等)
7. critisizing (解释同6)
8. winning (题型同 2. our/your/ their +名词,win是动词,所以要变成动名词winning )
9. inviting. (题型同6,7, 如果你知道without 也是介词,类似于of和for 就很容易做出判断了)
