Hello!<br/><br/>I learned that I can use the expression 'spend,waste + money, time + ~ing'. For example,<br/><br/> Monks can <font color="#0000ff">spend</font> years <font color="#ff1493">learning</font> how to make these paintings. <br/><br/>But, how about if I use 'to infinitive' instead of '~ing'? Will it be a wrong sentence? Like,<br/><br/> Monks can <font color="#0000ff">spend</font> years <font color="#ff1493">to learn</font> how to make these painting.<br/><br/>Or, just the meaning have changed?
