serious
adj. 严肃的，庄重的，严重的，危急的，认真的
I could have been a very different person. I might have been as good as you. I am not a bad man,but I have done wrong. Why am I telling you all this? Because you're the kind of person people can really talk to. You listen and can give them hope." "Do you think so,sir?" "I do.You see,when my life was difficult,I became desperate,and did some terrible things. Now all I can do is regret the past." "Asking forgiveness might help you,sir." "How do you know this,a young girl like you? You have never been out in the world,you have no experience in life. But you are right.I will try to lead a better life." I stood up.The conversation was becoming very serious,and hard to understand. "I must put Adele to bed now,sir," I said. "Don't be afraid of me,Miss Eyre. I have already said that you are a very serious person. You don't laugh very much,perhaps because of your hard life at the Lowood School. But I know you have a strong mind,and in time you will learn to laugh and talk freely. You are like a bird in a cage. When you get out of the cage,you'll fly very high.Good night!"
