Some scientists think that men are different from animals because they can think and learn. Others think that
13、men are different from animals because they can speak. Animals cannot speak. They make noise when they are afraid, angry and unhappy. Apes can understand some things quickly, but they are different from men. They cannot join words and make sentences. They cannot think like men because they have no l
14、anguage. They can never think about the past or the future. Language is a wonderful thing. Man can speak his own language very well when he is four or five, but no animal learns to speak. How do children learn? Scientists do not really know. What happens when men speak? Scientists do not know. They
15、only know that man can speak because he has a big brain.Classroom EnglishLets read the text.Read aloud, please.9Now lets do the exercises.Reading MaterialThe Browns and the GreensThere are five people in the Brown family. The Browns are from London. Mr. Brown is a scientist. He studies the differenc
16、e between men and animals. Mrs. Brown is an English teacher. They have three children, a son and two daughters. One daughter teaches in a technical school. Her name is Mary. The other daughter, Jane, is a student in high school. Their sons name is John. Jane and John go to the same school. They stud
17、y very hard. They like mathematics and physics very much. Jane wants to be a scientist. John wants to be an engineer.There are four people in the Green family. The Greens are from Califonia. Mr. and Mrs. Green are farmers. Their son, Peter, works in a factory during the day and studies physics at a
18、university in the evening. He wants to be a physicist. Their daughter, Ann, is a student in high school.Lesson NineTextThe ExperimentThe experiment is a basic scientific method. Scientist usually base theories on their observations and then test their theories by experiments. They use special appara
19、tus to make observations and carry out their experiment.10Here are two very simple experiments. Now look at the Picture A.What experiment is the man doing?He is making use of light from the sun to light a match.What instrument is he using?He is using a magnifying glass.What does this show?It shows t
20、hat light is a form of energy.Look at the Picture B. Take three candles of the same size and two glasses, one is big, the other is small. Stand the three candles apart and light them. Now they are all burning. Cover the first one with the small glass and the second one with the big glass. The last o
21、ne is burning in the open. Which candle flame dies out first? Which candle continues to burn? What does this show?Classroom EnglishTranslate the sentence into English.Hand in your exercise-books, please.Reading MaterialIn the physics laboratory.There are many laboratories in our university. Our phys
22、ics laboratory is near the library. We often go there to do our experiments. Our teacher goes there with us.All the students in the laboratory are very busy today. We are doing our lab work. Look at John and Peter. They are measuring the current. Mary is busy, too. She is taking the readings. They a
23、re 11working carefully. Our physics teacher works here every afternoon and helps us with our lab work. Now she is standing beside the blackboard.The laboratory technician by the window is showing some students how to read the meters. Those students are studying high-energy physics. They are all hopi
24、ng to be scientists, and physics is an important course for science students.Through experiments we can understand physics better. We also carry out research work here.Lesson TenTextEdison the inventorThomas Alva Edison was a great inventor and very practical man.As a little boy, he liked to ask que
25、stions. He wanted to know anything.When he was twelve, Edison began to make his own way in the world. He sold newspapers on the trains. This was his first job. When he first went to Detroit he visited the Public Library and saw many books. He made up his mind to read all the books there.At fifteen h
26、e established a “laboratory” on his train. It was the worlds first laboratory on wheels. He made experiments there.Six years later he went to New York. There he worked for some time as a telephone operator. But soon he took an interest in inventions. In a very short time inventions became his lifes
27、work. He wanted to invent new ways to use electricity for the interests of 12people. But he had no money. In 1868, he invented an instrument and then sold it. With this money Edison could establish his own laboratory and get some other scientists to help him.For sixty years Edison was the worlds lea
28、ding inventor. He made many, many inventions. His inventions changed our way of living.Classroom EnglishMay I ask a question?Answer my question, please.Reading MaterialMarys birthday presentsWhen she was a child, Mary Green took a great interest in Living things. Now, she is a good science student.
29、She studies biology at our university, and likes very much.She wants to set up a laboratory at home.Yesterday was her birthday. On her birthday, she wanted her family to give her useful presents, so all their presents had something to do with biology. Her father bought her a set of dissecting instru
30、ments. It was very expensive, but he did not mind because he wanted Mary to do well in her studies. Her mother gave her a microscope. It was expensive, too, but it did not cost as much as the dissecting set. Marys sister gave her a set of slides, and her little brother bought her a booka book of exp
31、eriments. He said he liked books most, and Mary agreed with him. With all these useful presents, she can set up her own laboratory now.13Lesson ElevenTextCountingHow did the early people do their counting? It is very interesting. In the early days people could not count as we do. Their method was ve
32、ry simple. At first they did all their counting with small stones. Later, they learned to use their fingers in counting. Since man has ten fingers, the number ten became the foundation of all counting in many parts of the world. This decimal system led gradually to a branch of mathematics. We call i
33、t arithmetic.Now we can make accurate computations with electronic computers. Computer can work very quickly and accurately. For example, a modern electronic computer can do over ten million computations in one second.The first electronic computers went into operation in 1946. Since then great chang
34、es have taken place in science and technology. With the help of computers productivity has increased greatly. Computers are of great help to us. That is why in recent years electronic computer have found wide application not only in production and scientific research, but also everyday life.Classroo
35、m EnglishIs that clear to you now?Are there any questions?14Reading MaterialSomething about the computerIn 1946 the first electronic computers went into operation. since its invention the computer has undergone many changes, and it has found more and more application. It can free people from complic
36、ated measurement and computation.Accurate measurement and exact computation are the bases of modern engineering and scientific research. For example, scientists usually test their theories by practical experiments. They have to make many computations before they can say that the results of their exp
37、eriments are correct. Yet there are complex computations in science and engineering. Scientists are unable to make them. But the computer can do them quickly and accurately. In recent years more and more people have used computers not only in production and technology, but also in everyday life.Less
38、on TwelveTextA trip to the MoonThe moon is a familiar object to you. You are familiar with its beautiful face. But do you want to know more about it?Well, lets take a trip to the moon. It will be a very long trip, for the moon is 240000 miles away. If we go by train at a speed of sixty miles an hour
39、, the trip will take over a year-six months each way. In fact, no train can go there.15Can we go there by aeroplane? We cant, for there is hardly any air once we have got ten miles away from the earth. An aeroplane cannot fly without air.Now we can make the trip by spaceship. Rockets can shoot us to
40、 the moon. Suppose that we really get there, we shall be in a quite different world.There are no clouds on the noon, for there is no water. There are no plants, and there are no animals. There is nothing living; or, if there are living things, they are not at all like the living things of this earth
41、. There is no air on the moon. Without air there can be no sound. Besides, you will feel very light on the moon. Day on the moon lasts for two weeks. During the day the sun is very hot. On the other side of the moon is night. The night is very cold.Do you want to stay on the moon? If not, let us get
42、 into our spaceship quickly and go home.Classroom EnglishTake out your exercise-books.Well have a short dictation.Reading MaterialAirA layer of air surrounds our earth completely. We call it the atmosphere. Without the atmosphere, we shall not be able to live on the earth. There will be no air for u
43、s to breathe. The earth will be very, very hot in the day and very, very cold during the night.Air is all around us. It is around us as we walk. When we sit 16down, it is around us. When we go to bed, air is also around us. We live in air.All living things need air. Living things cannot live without
44、 air. We can go without food or water for a few days, but we cannot live for a few minutes without air. We breathe in air.We need air in order to live. Do you know that fires too need air in order to burn? If there is no air you will not be able to make a fire.We know that air is around us everywher
45、e. We cannot see air but we can feel it. Simple experiments will show that air occupies space and has weight.Lesson ThirteenTextForecasting weatherA man had two daughters. One of them was married to a farmer, the other to a potter. One day the sky was covered with clouds. He set out to visit them. A
46、nd what did he see? The farmer was praying for the rain, while the potter was praying for a fine day.This little story shows how much man has felt concerned about the weather. Indeed, the weather has affected his life greatly. Therefore, men have always tried to observe, forecast and control the wea
47、ther. Now weather-forecasting has become a new science.Weather is different from climate. It is the current state of the atmosphere, while climate is the average state of the atmosphere over a long period of time. Weather changes constantly, while 17climate is comparatively stable.Weather-forecastin
48、g is organized all over the world. There are some 700 stations different parts of the world. Recently, satellites have been used for the study of weather.Next to observation and prediction, the aim of science is to change and control the weather. Much of this effort has been directed to small-scale
49、weather control.If we can control the weather successfully some day, who knows what may happen between different counties of the world! Weather control over one country might adversely affect the weather of another country.Classroom EnglishDo you understand?Yes, I do.Sorry, I dont.Please say it again.Reading MaterialWaterWater is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to dri
