推 HOTBIRD:用when就對了@@a? 04/02 19:19
我都這樣說
When+長/短, 長/短
While+長, 長/短
While直接接的句子得要是使用進行式的(長時間-持續動作)
When後面則是可以接進行式或簡單式(短時間-瞬間動作)
When the phone rang, I was doing my homework.
= While I was doing my homework, the phone rang.
= When I was doing my homework, the phone rang.
但 While the phone rang, I was doing my homework. (X)
兩長則是while when皆可
While I was doing my homework, my mom was mopping the floor.
= When I was doing my homework, my mom was mopping the floor.
