Question

spend time是todo还是doing

Answer 1

正确的是：spend time  doing  sth

spend 的搭配：（1）若表示"花费(时间、金钱等)做某事",则常用句型s some time (in) doing sth.介词in可以省略。

双语例如: They spent 4450 yuan buying the big colour TV set.   他们买那台大彩电花了4450元。  

（2）若表示"在......上花费(时间、金钱等)",常用句型 some time on sth.,介词on后接名词或代词。

双语例如: Kitty spends two hours on her homework every day.    Kitty每天花两个小时做家庭作业。

Answer 2

若表示"花费(时间、金钱等)做某事",则常用句型spend some money / some time (in) doing sth.,此时第二个动词要用动词-ing形式,介词in可以省略。例如:
They spent 4450 yuan buying the big colour TV set. 他们买那台大彩电花了4450元。
若表示"在......上花费(时间、金钱等)",常用句型spend some money/ some time on sth.,介词on后接名词或代词。例如:
Kitty spends two hours on her homework every day. Kitty每天花两个小时做家庭作业。
