標準的用法是spend time (in) doing 和 spend time on sth.
spend time on doing sth.各種文章裡有出現過,都算對的,on 往往和in 一樣,都可以省略的
沒什麼區別.都可以。
希望對你有幫助哦
沒有Spend time on doing sth.
有Spend time (in) doing sth.
有Spend time on sth.
如果這個結構中用介詞on, on後面不能出現動詞,on後面直接跟名詞。如果出現介詞in,就必須要有動詞,且介詞後面的動詞要用動名詞ing形式,介詞on可以省略。
例句:
1、I spend much time on my homework.
或者:I spend much time in doing my homework.
2、I spent ten yuan on this book.
或者:
I spent ten yuan in buying this book.
