Certainly dustmen prefer to be known as "Reuse Collection and Disposal Officers". You may think that this is rather 36 , and it is better to call a spade a spade. But dustmen can be as 37 as people of any other occupation, though we must 38 that their job is not a 39 one in the world. We often take dustmen for granted. Perhaps because they usually come very early in the morning, before most people are 40 .We are likely to forget their 41 .Our dustbins are 42 regularly, but we 43 stop to think about the men who do this. However, it is one of the most important jobs in the world, and when there are no dustmen to 44 the rubbish, the general 45 soon becomes aware that something is wrong. Recently, the dustmen of England went on strike for higher wages.
During the first few days it was regarded as a 46 .But when the first two weeks had passed, and the dustbins were overflowing in nearly every backyard in the country, the joke did not seem so 47 any more. 48 the strike continued, people could not 49 the hills of rubbish around their dustbins, and they looked for other places in which to 50 it. Even Leicester Square, in the heart of West End of London, was 51 high with plastic bags full of smelly rubbish. This was a（n） 52 attraction that the people of London were not at all 53 to see. Even when the strike was over, it took several weeks for the country to get cleaned up completely. Perhaps now the English people appreciate the work of 54 dustmen rather more 55 and won't take them for granted any more.

There was a boy who was sent by his parents to a boarding school (寄宿学校). 36 being sent away, this boy was the 37 student in his class. He was at the top in every 38 always with high marks.
But the boy changed after 39 home and attending the boarding school. His grades started 40 . He hated being in a 41 . He was lonely all the time. And there were especially dark times when he 42 committing suicide (自杀). All of this was because he felt 43 and no one loved him.
His parents started 44 about the boy. But they even did not know what was 45 with him. So his dad decided to travel to the boarding school and 46 him.
They sat on the bank of the lake near the school. The father started asking him some casual questions about his classes, teachers and 47 . After some time his dad said, “Do you know, son, why I am here today?”
The boy answered back, “To 48 my grades?”
“No, no,” his dad replied. “I am here to tell you that you are the most 49 person for me. I want to see you 50 . I don’t care about grades. I care about you. I care about your happiness. YOU ARE MY LIFE.”
These words 51 the boy’s eyes to be filled with tears. He 52 his dad. They didn’t say anything to each other for a long time.
Now the boy had 53 he wanted. He knew there was someone on this earth who cared for him deeply. He 54 the world to someone. And today this young man is in college at the top of his class and no one has ever seen him 55 !

I will never forget the two impressive things that happened last winter. One of my classmates and I were 36 our project work late at night on my university's campus far from home. Since there was 37 in the forecast, I had worn a winter 38 to school that day with a raincoat in my bag.
Throughout our work on the project, I could 39 that my friend was tired from a very long day working. As we stepped outside to begin the 40 walk home, I 41 she was shivering(颤抖). The temperature had dropped to the low thirties (Fahrenheit) and she 42 had a sweater on. I 43 offered her my warm jacket. She accepted it and asked me what I 44 wear then. I told her I had another one and pretended that my 45 was a jacket. She said later that she 46 the next morning and the first thing on her mind was feeling moved about my 47 of the jacket.
Coincidentally(碰巧), the next day I went to an open-air play and I was freezing 48 I didn’t expect it to be so 49 . A person who I hardly 50 insisted that I wear his jacket. I was 51 touched by this warm gesture. He was so matter-of-fact(讲究实际的) about me 52 his coat, too: he simply took it off and handed it to me telling me that I should 53 it. I used to think that this vast universe was a cold 54 . It turns out that even when the temperature drops low, the people never 55 to warm each other's hearts.
