2--Those majors are very different from each other.

1--I know, but I hate biology. I can't see myself studying it anymore.

2--You can change it, but you'll have to take more classes.

1--I don't mind. Political science is really interesting to me.

2--You would be graduating a year late.

1--Oh, no. I have to think a little more about this then.

2--I think you should change it, since you hate biology.

1--Yeah, you're right. I'm sorry I am so indecisive.

2--A lot of people change majors. It's normal.

1--But not as late as I did. I hate that I'm graduating after all my friends.

2--You're making the right choice.

译文：

1--我在想我可不可以把我的生物学专业换成政治学。

2--这两个专业彼此很不相同。

1--我知道，但我讨厌生物学。我不能看见自己再学习它了。

2--你可以换，但你不得不上更多的课。

1--我不介意。政治学对我来说真的很有趣。

2--你会晚一年毕业。

1--噢，不是吧。那我需要再好好考虑一下这个问题了。

2--我想你应该换，因为你不喜欢生物学。

1--是的，你说的对。很抱歉我这么犹豫不决。

2--很多人换专业。这很正常。

1--但不像我这么晚。我讨厌比我所有的同学晚毕业。

2--你在做出正确的决定。
