dearest从句子的结构看，空格的部分需要一个形容词，并且空格前面出现的the也提示我们空格部分可能需要形容词的最高级。而在原文的开头就提到“Of all the people around me，my mother is the dearest．”，因

Of all the people around me, my mother is the dearest. I love her and I enjoy spending time with her. In the future when she grows old, I will still stay with her. In my country the sons and daughters usually live with their parents. So when the parents are old, they won’t feel lonely. But in some other countries young people don’t like to live with their parents. Some of them even think their parents are a burden to them. In my opinion, old people know a lot of things that can help us and teach us. Therefore I enjoy living with my mother, especially when she is old and needs more of my love and care.
