The poor are very wonderful people. One evening we went out and we picked up four people from the street. And one of them was in a most terrible condition - and I told the sisters: You take care of the other three. I take care of this one who looked worse. So I did for her all that my love can do. I put her in bed, and there was such a beautiful smile on her face. She took hold of my hand as she said just the words "Thank you" and she died.
I could not help but examine my conscience before her and I asked what I would say if I was in her place. And my answer was very simple. I would have tried to draw a little attention to myself. I would have said I am hungry, that I am dying, I am cold, I am in pain, or something, but she gave me much more - she gave me her grateful love. And she died with a smile on her face. So did that man whom we picked up from the drain, half eaten with worms, and we brought him to the home. "I have lived like an animal in the street, but I am going to die like an angel, loved and cared for", he said at the end . And it was so wonderful to see the greatness of that man who could speak like that, who could die like that without blaming anybody, without cursing anybody, without comparing anything. Like an angel - this is the greatness of our people. And that is why we believe what Jesus has said: I was hungry, I was naked, I was homeless, I was unwanted, unloved, uncared for, and you did it to me.
And with this prize that I received as a Prize of Peace, I am going to try to make the home for many people who have no home. Because I believe that love begins at home and if we can create a home for the poor I think that more and more love will spread. And we will be able through this understanding love to bring peace, be the good news to the poor, the poor in our own family first, in our country and in the world. When I pick up a person from the street, hungry, I give him a plate of rice, a piece of bread, I have satisfied. I have removed that hunger. But to a person who is shut out, who feels unwanted, unloved, terrified, the person who has been thrown out from society, that poverty is so full of hurt and so unbearable… And so let us always meet each other with a smile, for the smile is the beginning of love, and once we begin to love each other naturally we want to do something.
What can be learned from the second paragraph？
A．The woman should have paid more attention to herself.
B．The man couldn' t blame anyone.
C．The author is religious.
D．The man died in the street.

This past fall semester, at Duke University, there were two students who were taking Organic Chemistry. They did pretty well on all of the tests and the midterms and labs,etc., such that going into the final they had a solid “A” . There two friends were so confident going into the final that the weekend before finals’ week，even though the Chemistry final was on Monday, they decided to go up to the University of Virginia and have a party with some friends up there. So they did this and had a great time. However, with the aftereffects of alcohol and everything, they overslept all day Sunday and didn’t make it back to Duke until early Monday morning.
Rather than taking the final then, what they did was to find Professor Aldric after the final and explain to him why they missed the final. They told him that they went up to UVA for the weekend, and had planned to come back in time to study，but they had a flat tire (爆胎）on the way back and didn’t have a spare and couldn’t get help for a long time and so were late getting back to campus.
Aldric thought this over and then agreed that they could make up the final on the following day. The two guys were overjoyed and relieved. So, they studied that night and went in the next day at the time that Aldric had told them. He placed them in separate rooms and handed each of them a test booklet and told them to begin.
They looked at the first problem, which was something simple about free radical formation and was worth 5 points. “Cool，" they thought, “this is going to be easy. " They did that problem and then turned the page. They were unprepared, however, for what they saw on the next page. It said: (95 points) Which tire was flat？
The two students decided to visit their friends at the weekend beacause_______
A.they didn’t want to take the exam
B.they were invited by their friends
C.they were not worried about the exam at all
D.they forget the arrangement of the final exam
They didn’t return as planned because_______.A.they got lost on their way back
B.they slept beyond the time to come back
C.their car broke down on their way back
D.they couldn’t get help when they were in difficulty
How did the Professor arrange the make-up exam？A.He made the exam booklet very long.
B.He gave them different exam papers.
C.He asked a very surprising question.
D.He gave them very limited time to finish the paper.
When they took the first glance at the exam booklet, they thought_______.A.it was easy
B.it was too much
C.it was too difficiult
D.it was reasonable
It can be inferred from the passage that_______.A.the students didn’t like Professor Aldric
B.the two students had difficulties in their studies
C.Professor Aldric was very clever and humorous
D.the two students would surely pass the make-up exam
