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.

    Many facts suggest that children are overweight (超重的) and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

    Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

    There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

    There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

    The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.
