PROBLEM: Article: Do you want to be a successful person? Would you like to know how successful people usually think and what drives them? Here I am going to tell you the key to success that successful people share. First of all, successful people never blame someone or something outside of themselves for their failure to move ahead. They realize that their future lies in their own hands. They understand that they can't control things in life, such as nature, the past and other people. At the same time, they are well aware that they can control their own thoughts and actions. They take responsibility for their life. Perhaps what most separates successful people from others is that they live life "on purpose" --- they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to deal with things around them. They hold the view that when they live their life "on purpose", their main concern is to do the job right. They live what they do. People want to do business with them because of their commitment. To live their life "on purpose", successful people find a cause they believe in and create a business around it. Besides, they never give up easily. Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals. To achievers always bear in mind what they don't have forever. Rather than see this as negative or depressing, they would use the knowledge to _ themselves on and go after what they want energetically and passionately. So keep in mind what successful people always hold to be true so that you will have a clear idea of what you should do to be successful in life.

PROBLEM: Article: A person who is deaf when he is born is usually dumb as well. There may be nothing wrong with his mouth and tongue, but he cannot speak. This is because he cannot hear people, so he has nothing to imitate . He may try to make sounds himself, but cannot hear his own voice. However, even though he finds it difficult to speak and cannot hear, he can learn to read. Nowadays such persons can also be taught to speak because we have modern methods and equipment, but we did not have these when Helen Keller was born. Even with modern methods and equipment, however, it is not easy for deaf children to learn to speak, though most of them succeed. When a child is deaf and blind as well, it becomes much more difficult, though it is possible. Helen Keller was born in 1880. She became very ill at the age of nineteen months. Medical knowledge was not as great then as it is now. She did not die but lost her sight and hearing. As a result, she became dumb as well. Her parents did their best to teach her, but she couldn't speak by the age of six. Then, in 1887, a teacher, Miss Sullivan, came to live with her. Miss Sullivan herself had been blind. She had been partly cured. Though she could not see very well, she was not blind. Helen was a difficult pupil at first, but in a month Helen had learned how to understand signs and how to make them herself. At last in spite of her great difficulties, Helen learned to read, write and speak, even though she was deaf and blind. She even went to college and had full education. She wrote many books, and though other people have written books about her, her own books are the ones that best explain how it feels to be deaf, dumb and blind. Her best book is The Story of My Life. Perhaps you have read it. Though it was written in 1902, it is still a very interesting book. Even if you have not read it, you may have heard of Helen Keller.
Answer: he cannot hear other people and he has nothing to imitate

SOLUTION: A person who is deaf at birth is also dumb because _ .

PROBLEM: Article: Milk was one of the main foods of people long before history was written. It will probably keep on being one as long as there are animals that give milk. Even the word "milk" is very old. It comes from Sanskrit ( ), one of the oldest languages known to man. A very old picture of _ has been found. It was drawn more than five thousand years ago. In the years long ago, people got their milk from their own animals. But later new inventions made the milk industry a big business. In 1851 Gail Borden found a way to take some of the water out of milk. This made it keep much longer. Four years later, Louis Pasteur introduced a way to kill the bacteria ( ) in milk. Next, a special milk bottle was made. This was followed by the invention of machines that could fill bottles with milk. These discoveries had a great effect on the milk industry. They meant that milk could be stored longer. Some people believe that milk drinking will become less popular that it has been. But remember how long milk has been an important food and think of many ways in which it is useful. It seems safe to say that milk industry will always be important.
