亲,spend的宾语后常可接以介词in〔on,for〕引导的短语表示“把…花在…上”,介词宾语可以是名词,也可以是动名词.以动名词作宾语时介词in常可省略,尤其在口语中.
1.Spend sth for sth/v-ing为…花费… use (an amount of money) to pay for (sth)
eg.Her husband spent thousand yuan for a second-hand computer.她的丈夫花了1000元买了一台二手电脑.
2.Spend sth (in) sth/v-ing 在…上花费 use up or consume sth
eg.She spent three hours in watching TV.她看电视耗掉了三个小时
3.Spend sth on sth/v-ing 把…花在… use sth for sth/sb
eg.He doesn't spend much time on his homework.他花在做作业上的时间不多.
eg.He spends a lot of money on entertaining friends.他把许多钱花在款待朋友上.
注意,介词In 和on 差别不大,只是我们在学习的过程中会偏向于这样记Spend ...(in)
doing sth/Spend ...on sth.

help sb (to) do sth / help sb with sth
这里的on 不是跟着help而是后面的farm
