英语延续动词与非延续动词的用法
动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。
1. 以上两类动词都能用于现在完成时，表示动作到现在为止已结束。
He has studied English for three years. 他学英语已有3年了。 
Mum isn’t at home. She has gone to the library. 妈妈不在家，她去图书馆了。 
2. 持续性动词在完成时中能与表示持续一段时间的状语连用，而瞬间性动词则不能。
His parents talked with the teacher for half an hour. 他的父母跟老师谈了半个小时。
My mother has lain in bed for 3 days. 我母亲生病卧床已经三天了。
3. 瞬间性动词在完成时中如要与表示持续一段时间的状语连用，通常有3种方法：
（1）用意思相当的持续性动词来替换。
He has been in the army/a soldier for 3 years. 他参军已有3年了。（不能用has joined）
She has been up for quite some time. 她起床已有好久了。（不能用has got up） 
Has your brother been away from home for a long time?

Last year around Halloween,I was invited to participate in a carnival (嘉年华) for Tuesday’s Child,an organization that helps children with the AIDS virus.At one booth (小隔间),anyone who wanted to could  1  on a piece of square cloth.Later that square was going to be  2  together with the others to make a quilt.The quilt would be presented to a man who had dedicated his life to this  3  and would soon be retiring. 
The boy sitting next to me was painting a  4 ,but it was dark,empty and  5 .At first I thought maybe he took the only paint that was left and it just  6  to be dark.But when I asked him about it,he said his heart was that color  7  his own heart felt dark.I asked him  8  and he told me that he was very sick.Not only was he very sick,but his mom was very sick.He said that his sickness was not ever going to get better and  9  was his mom’s.he looked  10  into my eyes and said,“There is nothing anyone can do that will help.” I could understand why he had made his heart a dark color.But I said to him,“It isn’t true that there is nothing anyone can do to help.But  11  can do things like giving bear hugs,which in my  12  can really help when you are feeling sad.” I told him that if he would like,I would be happy to give him one so he could see what I  13 .He instantly crawled into my  14  and I thought my own heart would burst with the love I felt  15  this sweet little boy. 
He sat there for a long time and when he had had enough,he jumped down to  16  his coloring.I asked him if he felt any  17  and he said that he did,but he was still sick and nothing would change that.I told him I understood.I walked away feeling sad,but recommitted to (重申) this cause.I would do whatever I could to help.As the day was  18  to an end and I was getting ready to head home,I felt a tug (拉) on my jacket.I  19  and standing there with a smile on his face was the little boy.He said,“My heart is changing colors.It is getting  20 .I think those bear hugs really do work.” On my way home I felt my own heart had changed to a brighter color.
