动名词（v- ing）的用法
语法定义
动名词是由“动词原形+-ing”构成的，但是它不是表示正在做，而只是表示“做……”这件事！“动词原形+-ing”有两种叫法，如果呈现的是名词词性就叫__________，呈现的形容词、副词词性时就叫 _______。动名词的构成和现在分词一样，但功能完全不同，动名词具有名词的功能，又保留了动词的性质。分词具有形容词、副词的功能且保留了动词的性质。因此动名词在句中作_______________________等。
“动名词”
“分词”
主语、宾语、表语、定语
【例句】1. Come and sit by us.
2. Peter goes to work by bus every day.
3. Tony will come back by 10:00 pm.
4.English is spoken by many people.
【结论】
by表示位置，意为“__________ ”，如句1。
2.by+表示交通工具的名词(by后不加冠词 )，意为“ ”，如句2。
3. by+时间, 意为“ ”，如句3。
4. 用于被动句中，表示行为主体，常译 作“____/______” 等。
乘/坐...
