用英语写为什么心情好

1.Because it is sunny outside.
2.Because I get a good mark in my examination.
3.Because my parents buy me new presents.
4.Because I can have time to enjoy cartoons.
5.Because I need not to worry about anything.
{全部写得很简单,因为你说得要求太抽象了,况且让我心情好的条件是在是太简单了,有时只要人家说一句“你今天真有精神就行了（You are energetic today.)}
