Bob is eleven years old. One day, his friend Jenny said to him, “I'm going to have a birthday party on Saturday. Bob, can you come?”

      Bob asked his mother, and his mother said, “Yes, you can go.” On Saturday afternoon, his mother said to him again, “Now, Bob, when you go to the party, you must be polite(礼貌的), and don't ask for food until someone gives it to you. ”

     “All right, Mom.” Bob said, and he went to Jenny's house by bike.

      There were many children at the party. They played games for about an hour, and then Jenny's mother gave them some food, but she forgot Bob and didn't give him any. After a long time, he took up his plate（盘子）and said loudly, “Does anyone want a nice clean plate?”

    A man in Pakistan is now working to help children get an education. When he was a child, he did not go to school because he was too poor.

    It is reported that Pakistan has 25 million children who do not go to school. That is the second ­highest number in the world. Only Nigeria has more. Many Pakistani children must work to support their families.

    Mohammad Ayub was once one of those children. He is now a firefighter. He also manages a small school. VOA recently visited the school in the capital Islamabad.

    Ayub started with just one student in 1982. He saw a boy cleaning cars for days. He asked him, "Why don't you go to school?" The boy answered that his parents were dead and he had to work to help support his five brothers and three sisters.

    Ayub was also an orphan and he, too, had to work to help support his five brothers and three sisters. He said, "When my father died, everyone who came to the funeral said they were sorry, but no one helped." He sold newspapers and did other work to earn enough money to pay school fees for his brothers and sisters.

    Ayub wanted to help the young boy who washed cars, but he did not have enough money to pay the boy's school fees.

    Today, Ayub teaches many children at his school in a public park. Some of the children attend other schools in the morning, but come to Ayub in the afternoon to get help with their homework.

    Ayub has helped a large number of poor children since he began teaching. Many of them come from very poor areas near the park.

    Ayub said," I used to argue with kids who worked ' Why are you washing someone's dishes or their clothes? Why don't you study? ' "

    One of the children he advised to attend classes was Farhat Abbas. Ayub found him working with his friends about 12 years ago. "He followed us back home. He told our parents he wanted to teach us and asked them to send us to his school, "Abbas said.

    Today, Abbas is taking classes at a college and is helping Ayub.

    Many children are out of school, and those who do attend classes often get a poor education. Information gathered by an organization shows half of all Pakistani children in the 5th grade do not understand basic mathematics and cannot read a story in their language.

    A group in Islamabad reports Pakistan spends less on education than any other country in South Asia.

"Where was the cashier (收银员)?" I wondered. Feeling1 with having waited at the counter ( 柜 台 ) for at least 3 minutes, I quickly looked at my watch. I was afraid I2 had enough time to eat a sandwich and then rushed back to work.

When I looked around the nearly empty3 , I saw a woman cleaning a table in the corner. She looked at me coldly with sad, dark eyes.

I felt so angry that I was almost out of4 . Suddenly I remembered Mom's words. "5 you find yourself in an unpleasant situation, just think about what is missing. If someone is6 , then kindness is missing. If someone is hateful, then 7 is missing. If we will do what's missing, then we will provide whatever the situation needs."

And here I was in an unpleasant situation.8 should I do "what's missing"? What was missing was service. Should I just jump behind the counter to take the food I would order?

Just then the woman walked slowly towards me. "May I help you?" she asked, still 9 .

She looked so tired.10 , she was overworked.

I took a deep breath. With Mom's words still ringing in my11 , I gave the woman my order and smiled. "How are you doing today?"

My question seemed to 12 her. She looked at me for a second before answering. "Not too good."

"I'm sorry," I said, "I hope it gets better from right now."

She almost smiled as she handed me the food. "Thanks. I hope you're right."

I thought to 13 as I ate my sandwich. We're the same, really. We have problems and angers, we get tired and we hurt. We need to be14 to each other.

After eating, I cleaned the table cleaner than usual, and put the tray (托盘) back nicely on the stand. The woman was watching me all the time, with a big smile on her face.

"Do what's missing." What mum said really15 .I smiled back to her, too.

 Who would have thought that Albert Einstein, {#blank#}1{#/blank#} famous German- American scientist from the early 1900s, would make it into the news these days? But that's {#blank#}2{#/blank#}(exact) what happened. Recently, his handwritten work notes about the theory of relativity(相对论) went up for auction(拍卖).

 Einstein, along with an {#blank#}3{#/blank#}(Italy) engineer Michele Besso, worked together for several years on a scientific paper. They hoped to come up {#blank#}4{#/blank#} a mathematical equation(数学方程式) to explain the theory of relativity. It {#blank#}5{#/blank#}(involve) the factors of energy, mass and light.

 They ran into {#blank#}6{#/blank#}(problem) and stopped working on it, but Besso saved the written papers anyway. Einstein didn't successfully finished the work {#blank#}7{#/blank#} he realized that gravity also needed to be considered. He finally published a paper about it on his own in 1915. After all these years, the 54 pages of notes were recently put up for auction at Christie's (佳士得拍卖行) in Paris.

 The buyer's name was not released, but the manuscript (手稿) is {#blank#}8{#/blank#}(expensive) scientific paper ever bought, at over $15 million. One has to wonder {#blank#}9{#/blank#} the owner is going to do with those notes. Frame them? Keep them in a vault(保险库)? Resell them {#blank#}10{#/blank#}(make) even more money? Only time will tell.
