一下是朗文当代词典的解释：可以看出imitate比emulate多一个意思
imitate:
1 to copy the way someone behaves, speaks, moves etc, especially in order to make people laugh (带有哗众取宠的意味)
2 to copy something because you think it is good （模仿某件事情，因为你认为那件事情是正确的）

emulate:
to do something or behave in the same way as someone else, especially because you admire them [= imitate] （模仿某人，因为你崇拜他）
