几个英语问题``
1、I just stay at home doing my homework.
这里为什么要用doing呢?
2、海南岛在中国南部.(三个空哦）
Hainan Island is in ____ _____ _____China.
能不能用“Hainan Island is in southern part of China."呢?

1、I just stay at home doing my homework.
这里为什么要用doing呢?
这是非谓语动词的用法.非谓语动词有三种形式包括（to do\doing\done）
就是除了谓语都可以充当
to do 形式表示将来或目的
如：To improve my English ability,I must study hard.
为了提高我的英语水平,我不得不努力学习（为了表目的用to）
doing 形式表示主动或正在进行
如：There are more wonderful and exciting things waiting for you in new BeiJing now.北京现在有好多新奇的事物在等着你（things正在等你表进行中用doing）
done形式表示被动或完成
I find my pen broken.我发现我的笔坏了.（笔已经坏了用done表完成）
至于你的那句I just stay at home doing my homework.我呆在家里做我的家庭作业（表正在进行用doing)
2、海南岛在中国南部.(三个空哦）
Hainan Island is in _the_ _south_ _of_China.
能不能用“Hainan Island is in southern part of China."呢?
Hainan Island is in the southern part of China就对了
