The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鸽子). Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way.
Human (人类的) messengers (persons carrying messages) are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system(电子印刷系统) could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each.
Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about the pigeons in the newspapers around the world

   Do you know that women's brains are smaller than men's? Normally the women's brain weighs 10% less than men's. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it's what's inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（数量）of “thinking” brain is almost the same in both men and women.
   It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it's women who come out on top every time.
   There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life's great mysteries: why men refuse to ask for directions … and women often need to!
   The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

MSG(monosodium glutamate谷氨酸单钠) is a food additive(食品添加剂),which has been widely used by many food factories all over the world since it appeared first in Japan in 1909.

MSG is a substance that is added to some food to improve its taste and color. It is used in foods around the world such as cakes, bread, frozen meat, fish and vegetables. In the beginning, people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed to have bad reactions(反应) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat . It was also reported that MSG excited a person's brain and caused his death in Japan. Scientists think that MSG may lead to many neurological disorders(神经紊乱). In mice studies done by a university, the result showed the mice didn't want to eat the food including MSG.

Today many food companies “hide” MSG on food labels(标签) by using different names. If you see “natural flavorings (调味品) ”,“hydrolyzed protein” and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very delicious to taste, but sometimes it is dangerous for our health because some harmful food additives have been added to the food.

To protect people's health, our governments, from central to local, are taking action to stop factories producing harmful food additives.

Everyone has got two personalities (性格)—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.

If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by new ideas. You don't like to make people unhappy, so you never express your real feelings. You're quite shy and you aren't very confident.

If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.

If you sleep on curled up (蜷缩) , you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You're shy and you don't usually like meeting people. You like to be on your own.

If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel worried, but you don't often get unhappy. You always say what you think, even if it makes people angry.

Basketball, running and swimming are popular events (项目) at the Olympics. But there are also some events that are not as popular. Some are even very strange. Let's see if you have any knowledge about the following events.

Tug-of-war

This event started in 1900 and left the Olympics in 1920. The team wins if they pull the rope past a certain point first. Interestingly, more than one team from a country can enter in this event. This makes it possible for one country to win several medals

Rope climbing

It first appeared as an Olympic sport in 1896. The climber who spends the shortest time reaching the top is the winner. The rope used to be 15 meters long. Years later, it was shortened to 8 meters, for some reason. After 1932, there was no rope climbing in the Olympics.

Race walking

In race walking, walkers have to win the race by walking. To make sure that they do not run, race walkers must have one foot on the ground at all times. Race walking has been an Olympic sport since 1904. Men enter in 20 kilometer and 50 kilometer races; women only race 20 kilometers.
