Some radio signals are reflected when they meet solid objects; for example, television signals are reflected when they meet walls and houses, and when meet an aircraft in the sky. The picture is not clear when the signals are reflected like this. When a plane is flying near the house, the picture on the television screen sometimes dances about in a very troublesome way.These reflections, which led Watt to the science of radar, are now used a great deal. Radar instruments can show the direction and distance of aircraft. The signal are reflected only when the instrument points at the aircraft; this shows the direction. How do we find the distance?Electromagnetic waves travel at a speed of 186,300 miles per second. We know when the signal is sent out; we notice when it is received back. The signal takes a small part of a second to go and return, but this time is known. So we know the distance from the ground to the plane.Radar is very important to ships on the sea. In most big ships, a radar instrument is always watching the sea on all sides. If any other ship reflects its signal, a white spot is shown on a screen on board. Big aircraft also use radar. The instrument finds other aircraft in the sky. A mans eye is not good enough to do this because it cannot see far enough; but the radar beam can see for many miles.

A dream is made up of a series of mind-pictures that form during sleep. The people and actions in these pictures seem real to the person who is dreaming. When a person is asleep, he has little or no control over his mind. Then ideas and feelings come out to form the mind picture known as dreams.Dreams may be influenced by different things that are present during sleep. If a person is cold, he may dream that he is out in a snowstorm. Worries or anger may also influence the content of a dream..Some people think that they seldom dream, and other people are quite sure that they do not dream at all. Studies of human sleep have shown, though, that everyone dreams every night. If a person thinks he does not dream, it is because he does not remember dreaming when he wakes up. Usually, a person may dream three to seven times for a total of one or two hours of dreaming every night.Perhaps you are wondering just how research workers can be sure that a person is dreaming. The story behind the discovery is an interesting one.During their research studies of human sleep, Dr Kleitman and his assistants noticed that a person sleeping made sudden eye movements. These eye movements occurred at least several times a night. When a sleeper was awakened during these periods of eye movement, it was learned that he had been dreaming. In most cases, the dreamer could then recall his dream. The persons eye movements, scientists believe, were caused by the movements of his eyes as he followed the events of the dream. Not only does everyone dream, but it seems that we all need to dream. One theory is that dreaming gives us a chance to escape from the rules of our real world. In dreams we can see our wishes come true. We can be rich, powerful, successful.Another theory is that in our dream we are trying to work out our problems that have troubled us during waking moments.Whatever the explanation, we all do dream, and dreaming is necessary and important to us.

[1] One day sixty-seven years ago, a young man had an accident on his motorbike in which he suffered a few apparently minor injuries. There was a bruise on the left side of his forehead and some slight bleeding from his left ear. He was taken to hospital for examination but X-rays did not reveal any other injuries.Nevertheless, the doctor who was treating him decided to keep him in hospital for further observation because the young man was having difficulty in speaking and seemed very confused.[2] At the time of the accident, the young man was twenty-two years old, and the date was August 1933.A week later he was able to carry on what seemed a perfectly normal conversation.However, he told the doctor that he was only eleven years old and that the date was February 1922.What is more, he could not remember anything that had happened since 1922.For example, he could not recall having spent five years in Australia, or coming back to England and working for two years on a golf course.[3] As time went by, part of his memory of the eleven missing years came back.A few weeks later, he even remembered his years in Australia.But the two years of his life just before the accident were still a complete blank.Three weeks after his奥鹏华中师范大学平时在线作业 injury, he went back to the village where he had been living for those two years.Everything looked unfamiliar and he did not recall ever having been there before.[4] Despite this, he was able to take up his old job again in the village and to do it satisfactorily.But he often got lost when walking around the village and found it difficult to remember what he had done during the day.Slowly, however, his memory continued to return so that, about ten weeks after the accident, he could even remember most of the previous two years.There remained only one complete gap in his memory: he could remember absolutely nothing about what he had done a few minutes immediately before the accident or the accident itself.This part of his memory never came back.

[1] Many primitive peoples believed that by eating an animal they could get some of the good qualities of that animal for themselves. They thought, for example, that eating deer would make them run as fast as the deer. Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave.Man-eating may have started because people were eager to become as strong and brave as their enemies.[2] Among civilized people it was once thought that ginger root by some magical power could improve the memory. Eggs were thought to make the voice pretty.Tomatoes were also believed to have magical powers. They were called love apples and were supposed to make people who ate them fall in love.[3] Later another wrong idea about tomatoes grew upthe idea that they were poisonous. How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.[4] Even today there are a great many wrong ideas about food. Some of them are very widespread.[5] One such idea is that fish is the best brain food. Fish is good brain food just as it is good muscle food and skin food and bone food. But no one has been able to prove that fish is any better for the brain than many other kinds of food.[6] Another such idea is that you should not drink water with meals. Washing food down with water as a substitute for chewing is not a good idea, but some water with meals has been found to be helpful. It makes the digestive juices flow more freely and helps to digest the food.[7] Many of the ideas that have no foundation, according to scientists, have to do with mixtures of foods. A few years ago the belief became general that orange juice and milk should never be drunk at the same meal. The reason given was that the acid in the orange juice would make the milk curdle and become indigestible. As a matter of fact, milk always meets in the stomach a digestive juice which curdles it; the curdling of the milk is the first step in its digestion. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.[8] Still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk probably the single best food, contains both proteins and carbohydrates.It is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.
