问题解答：

1：”数学更好理解，因为我感兴趣”．Maths is easier to understand,because I'm interested in it.
2：”我去过北京和上海”．I have been to Beijing and Shanghai.
3：”我经常运动”．I often play sports / take exercise.

1. Maths is easier to understand, because I'm more interested in it.

2. I have been to Beijing and Shanghai.

3. I often do workout/take exercise.(workout只做一些有氧运动，如跑步机，举哑铃等等，后面是指做一些体育锻炼，如做健身操等等）如果是玩具体的体育运动，比如踢足球等，一般直接说I often play football.
