Among the few scientists who have had a great effect on science and history, Albert Einstein is perhaps the        (great). An American university president once commented that Einstein had created        new view of the universe. His theory has        (complete) changed the way scientists understand time and space. Now, more and more people agree that the universe is something more complicated than        they have ever thought before.

Einstein        (bear) in Germany in 1879. In 1914, young Einstein, already internationally famous, became a professor at an institute in Berlin. He had few duties, little teaching and unlimited opportunities for study. However,        (he) peaceful life was soon broken by the First World War.

Einstein hated violence. He was deeply affected by the war; he sat        (happily) in his office doing nothing and lost interest in his research. Only when peace came in 1918 was he able to get back to work.

In the years        (follow) the First World War, people showered honor upon him. He became the head of the Kaiser Wilhelm Institute of Theoretical Physics. In 1921 he won the Noble Prize        Physics and was greatly honored and respected in Germany. However, his life was again disrupted. The Second World War broke out and Einstein had to move to the US，where he lived until his       (die) in 1955.

    Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. “Houses” have been the most popular area for discoveries and inventions in the past and even now.

    Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions.

    A lot of inventions have been made recently in the household field. The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. All the outdoor dust, mud and snow can be kept out of the house by installing(安装)the dirt drain(排水管)at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid is closed.

    These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores and in a more useful manner.

Albert Einstein(1879—1955) was one of the greatest and most original scientific thinkers of all time.

Born of Jewish parents in Germany, he completed his education in Switzerland and got his Ph.D at the University of Zurich. He went to live in the United States in 1933 because of the rise of Nazism(纳粹) in Germany and Hitler's persecution(迫害) of the Jews.

In 1905,while still at Zurich,he published his Special Theory of Relativity, which was based on things everyone may have noticed. If two trains are standing alongside each other and one train starts to move, a person sitting in the train may wonder whether his own train is moving or the other is moving, and before he finds out what is happening, he can see that one train is moving relatively to the other. From this and also from other more complicated facts, Einstein came to the conclusion that all motion is relative and that there are really no such things as absolute(绝对) motion. Some of the other conclusions he drew are that nothing can go faster than light, and that if something such as a ruler was moving faster and faster it would seem to get shorter and shorter as its speed was near the speed of light. By 1915, Einstein had made known his General Theory of Relativity. He also improved on Newton's theory of gravity. Most of his theories have been tested and found to be true though some may sound strange. For his important work he was awarded the 1921 Nobel Prize for Physics.

One day I happened to find a chatting room in my QQ, there people were chatting in English.        

I tried to chat with some of them. To my surprised, I found the oral English of some junior        

students were better than me. I asked them for advise and they told me to practise more on QQ.                     

But every day after that I would spend one hour practise my oral English on QQ. Day by day I              

learned from many useful words and expressions. With time went by, I found that I could even               

communicate some college students freely.
