Adam Braun set up the organization(组织) Pencils of Promise in2008. Its goal is to make sure all children have a chance for education. Six years later , the non-profit organization is building a new school somewhere every 90 hours.It has helped more than 22.000 children in Africa,Asia and Latin America.

 It all started when Adam Braun was a college student. He was visiting India when a boy stopped him and asked for money on the street, Mr. Braun asked the boy what he would want, if he could have anying in the world.

“I thought the answer was going to be  'a house' or 'a car' or 'a boat'.His answer was 'a pencil'.So I gave him my pencil and he was just happy and excited . I  realized he never had been to school before ,and that was the reality(现实) for 57 million children around the world. " Braun said.

 Adam Braun started working in finance(金融) after he graduated from college, But he never forgot the boy and the problem he realized.

“We live in a world in which every child can have a chance to get a good education ,because we have everything necessary already.We are able to educate every child .  So I promised to help create that world .” Braun said.

  Mr Braun raised money for his project. He paid for building the first Pencils of Promise school,in Laos, five years ago. Since then ,his organization has helped pay for more than 200 schools in the countryside of Laos,Nicaragua,Guatemala and Ghana.

   Have you ever wondered who is killing time in the cafes at three in the afternoon while you are busy at school? Linda and I found the answer when we got part-time jobs at Starbucks and KFC during the summer vacation?

    Look! People are gathering to get water from a huge well in the village of Natwarghad in the western Indian state of Gujarat! ①Because of the large population on the earth, the world is ________hungry, it is ______be thirsty for water now. The world's population has reached 7 billion. And it could possible grow to 15 billion by the year 2100.

    ②On the other hand, about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink or use the other 3% of fresh water which comes from rivers, lakes and underground. And we can't even use all of that, because some of them has been polluted.

    Now more water is needed. The problem is: can we avoid a serious water shortage later on? Firstly, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Today, in most large cities water is used only once, but it can be used again .Even if every large city reuse its water, still there would not be enough. What could people turn to next?

    The sea seems to have the best answer. The sea is very big. Look at the map of the world, there is more sea than land. It covers three quarters of the earth. All that needs to be done is to get the salt out of the sea water. Scientists are trying to find a cheaper way of doing it. So you see,③如果我们可以找出解决方法，我们就不会有干涸（dry up）的危险。

    We need animals. Every animal has its place in the balance(平衡) of nature. We should try to help save the animals.

    Some people think zoos are good places. The zoos give the animals the comfortable and safe living places. If the animals get hurt or ill, people will take care of them. The zoo is a good place to know the rules in the wild world. We can be much closer to nature. We can know more about the animals in the zoos by watching, listening even smelling instead of just looking at the pictures in books.

    Some people don't think animals feel happy in the zoos. Animals like pandas, wolves and bears usually live in the wild. They play and find food by themselves. They are free and happy in the wild. If they are in the zoos, food is enough and rooms are comfortable. They do not need to do their best to find food to eat or places to stay in. They just walk around, sleep day and night, but they are not free at all.

    I think we should build national parks as wild life nature reserves to protect animals. If we do nothing, animals will get fewer and fewer.

    You may think that English dictionaries have been used for many, many centuries. The spelling of English has always been a problem, but it was more of a problem in the days before a dictionary. In those days people spelt words in different ways which you might find interesting. But it made reading English much more difficult. So dictionaries were invented to encourage everybody to spell the same. In fact, an English dictionary like the kind you use today wasn't made until the time of the Qing Dynasty.

    The largest dictionary in the world is the Oxford English Dictionary, or OED for short. The idea for this dictionary came from an important meeting in Britain in 1857. Twenty-two years later, Oxford University asked James Murray to be the editor of its new dictionary.

    Murray had not been to college. At the age of fourteen, he left his village school in Scotland and taught himself while working in a bank. Later he became a great teacher. After Oxford gave him the job, Murray had a place built in the garden behind his house to do his work. Part of it was one metre underground. In winter he had to wear a heavy coat and put his feet in a box to keep warm. Every morning, Murray got out of bed at five o'clock and worked several hours before breakfast. Often he would work by candle light into the evening.

    Murray hoped to finish the new dictionary in ten years. But after five years, he was still adding words for the letter A! Then others went to work with Murray, and his two daughters were among them. He worked on the dictionary until he was very old. Forty-four years later, in 1928, other editors finished it. It had more than 15,000 words in twelve books. And you thought your English dictionary was big!

    Remember when you were a little child trying to learn to walk？

    First, you had to learn how to balance (平衡) yourself and stand. You fell down, and then got back up. You laughed sometimes and cried at other times. After much practice, you finally learned how to balance yourself. You got much pleasure from this new feeling of power—you'd stand everywhere you could. It was a happy time—you did it!

    Now the next step—walking. You'd seen others do it. It didn't look that hard—just move your legs while you were standing. Wrong—more difficult than you ever imagined. But after you tried again and again and again, you understood how to walk.

    If people found you walking, they cheered, "Oh, look at what the kid is doing." This encouraged you! But look back on those days when you were the little child—how many times did you try when no one was watching, or when no one was cheering？ You couldn't wait for someone to encourage you to take the next steps. You learned how to encourage yourself.

    So, keep trying and encouraging yourself as you learned to walk if you want to succeed in doing something.
