Since he is so hard-working ,he would not mind doing extra work for the Students'Union

问题描述:

Since he is so hard-working ,he would not mind doing extra work for the Students'Union
这一句中为什么不用will用would,would不是will的过去式吗?这到底什么时态啊,

would更多情况下是表示愿意/意愿.比如说Would you like to go out for a walk with Jim?
那句中的用法是somebody would / would not mind doing something,意思是某人介意或者不介意做某事
