There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community(医学界)a method of fighting heart disease, has had some unintended side(effect) such as overweight and heart disease—the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt(remove) from food, the food tastes as if is missing something. Asresult, people will eat more food to try to make up for that something missing. Even(bad), the amount of fast food that people eat goes up. Fast food(be) full of fat and salt; by(eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be(care) not to go to extremes. Like anything, it is possible to have too much of both,is not good for the health.

    Things You Didn't Know About Stephen Hawking

    Even if you don't keep a close eye on new developments in physics, you've probably heard of the famous physicist Stephen Hawking.

    These days, we know Hawking as a brilliant mind whose theories are difficult for a nonscientific mind to grasp. This is why it may come as a shock to learn that Hawking was a slacker when it came to his school studies.

    With a little more effort, he brought those grades up to about average, but not much better. However, from an early age he was interested in how things worked. He has talked about how he was known to take apart clocks and radios. However, he admits he wasn't very good at putting them back together so they could work again.

    Stephen Hawking took a liking to mathematics from an early age, and he would have liked to have majored in it.He hoped Stephen would instead study medicine.

    But, for all his interest in science, Stephen didn't care for biology. He has said that he found it to be “too inexact, too descriptive (叙述的)”

One problem, however, was that Oxford didn't have mathematics as a major. The result was that Stephen would attend Oxford and major in physics. That's why he chose to study universe.

A. His father wanted to send him to Oxford.

B. His father, Frank, however, had different ideas.

C. Actually, he focused on the bigger questions.

D. He would have rather devoted his mind to more precise concepts.

E. In fact, when he was 9, his grades ranked among the worst in his class.

F. However, there're many interesting facts you might not know about him.

G. Both his teachers and peers seemed to understand that they had a future genius.

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.
