Many of the world's pollution problems have been caused by the crowding of large groups of people into the cities．Supply for the needs of the people leads to further by industry．If the rapid increase of world population continues at the present rate, there may be much greater to human beings．
Some scientists speak of the increase in numbers of people as "population pollution''．
About 2,000 years ago, the world population was about 250 million．It a billion in 1850．By 1930 the population was two billion．It is now six billon．It is to double by the year 2020．If the population continues to grow at the same rate, there will be 25 billion people in the a hundred years from now．
Man has been the earth's resources more and more over the past years．Some of them are almost gone．Now many people believe that man's greatest problem is how to control the of the population．The material supplies in the world will be far from enough to the human population if the present rate of increase continues．
There is already over-crowding in many cities and starvation in some countries．Many people believe that human survival in the future on the answer to the question．

As soon as I saw the cat in our yard, I knew he was a stray (流浪儿). He looked —a wounded warrior with a badly scarred (有伤疤的) body.
I started putting out food for him each day, but he wouldn’t come near me if other people were . Winter came, and he still wouldn’t us. Then, one day, a car hit him so we took him to the
vet’s.
After a week, we were eager to bring him home to our family. But when we went to take the cat home, the vet told us we should put him to immediately because the cat was so fierce and meant that he would become tame (驯服的), let alone a pet.
But I have always had in love’s power to even the wildest beasts. I told the vet, “I want to take him home.” We him Paws.
Three days went by, and we only knew Paws was the bed because when we walked past it we heard deep growling.
I wanted to somehow let him know he was and loved. So I put on a hard hat and a pair of welding gloves. I under the bed toward Paws, with my face to the and only the top of my head facing him. I out to stroke (抚摩) him gently over and over again.
He growled and tried to and bite me. It was scary—but I knew he couldn’t me, so I just kept going. Slowly, he began to . Then I slid out from under the bed and left the room.
Several hours later, I noticed a cat on the bed. It was Paws—all on the pillows! I couldn’t believe it.
That dear cat became the of our household. Although Paws finally died of cancer, his legacy(遗赠)—my and firm belief in the power of love—lives on.

I will never forget what my old headmaster has taught me. when you are only 15 years of age, you do not remember most of the things that are taught by your teachers. However, this story is one such lesson that I will never forget. Every time I drift off course, I get of this story.
It was a normal Monday morning he was the students on important things in life and about ourselves to what is important to us. This is how the story .
An old man lived in a certain part of London, and he would every morning and get the train right to Central London, then at the street corner and beg. He would do this every day of his life. He sat at the same street corner and had begged for almost 20years.
His house was and unpleasant smell came out of the house. The neighbors could not the smell anymore, so they called the police officers to this place. The officers knocked down the door and cleaned the house. There were small bags of all over the house that the old man had collected over the years.
The police counted the money, and they soon realized that the old man was a . They waited outside his house, expecting to the good news with him. When he arrived home , he was met by one of the officers who told him that there was no for him to beg any more. He said nothing , but went into his house and locked the door. The next morning he begged as usual.
Obviously, this old man had no great plans, dreams or anything significant for his life. We learn nothing from this story staying focused on the things we enjoy doing.
We should remain true to our course, which may mean committing ourselves to things that people around us would normally ,let nothing else determine our fate, but ourselves.
What makes us happy is what in the end, not what we get.
