求翻译：在暑假里，我有许多事情要做。最重要的是学习。我准备好好的复习一下以前的学科和预习将要学习的学科。当然了，除了学习，健康也很重要。我每天都会打篮球。我可能还会和爸妈去海南旅游，海南非常美丽。是什么意思？

In the summer vacation, I have many things to do. Most important is to learn. I'm going to have a good look of subject disciplines and prepare before going to study. Of course, in addition to the learning, health is also important. I play basketball every day. I may be, and MOM and dad go to Hainan tourism, Hainan is very beautiful.
