Ancient Greece

The Greeks were the greatest (great) sailors of their time. Greece has one excellent_ 41_ (nature) feature-- the coastline. That's why many Greeks left the mountains and_ 42_ (take) to the sea.

The ancient Greeks have __43_ (give) the world many ideas about life and how to live it. The idea of democracy (民主) started in Greece. So did many ideas of science, religion and_44 (govern). But these ideas did not come out of Greece as a whole. Instead, they grew up in_ 45___ (differ) cities throughout the Greek Empire.

The cities of Greece grew up in valleys near the sea. Each city was_ 46__ (separate) from the others by mountains. The roads _ 47 _ (connect) the cities were narrow and winding. Each city governed itself in its own way. And the_ 48__ (citizen) of each city were very proud of its way of life. In fact, each city was_ 49_ (real) an independent state. Such places are called city-states by_ 50_ (politics) scientists.

t. Even when people in different countries eat the same food, they often prepare it very differently. If you were in Germany, you would find soup that is thick and heavy. If you were in China, you would find soup that is thin and clear. On holidays most of us eat special foods. Year after year, even if many other things change, the food is always the same. Sometimes housewives begin weeks in advance to prepare the special foods that are traditionally served on certain holidays.

People in different parts of the world also have different ideas about what is good to drink. Among the most popular hot drinks are coffee and tea. Coffee is very popular in northern Europe and in the Middle East. Some people put cream and sugar in their coffee. But in the United States, many people drink their coffee "black" that is without cream or sugar. Tea is the national drink in China, Japan, and other Oriental(东方的) countries. In the Orient, people drink tea without sugar. But in England where it is also a national drink, many people use both sugar and hot or cold milk in their tea.

People in different parts of the world______.

A．cook the same food in different ways

B．like the same kinds of food

C．have the same ideas about foods

D．know how to prepare the same food

rent from those of others？ The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

Questions （1）to（5） are based on the following passage:

What makes a person a scientist？ Does he have ways ---or tools ---of learning that are different from those of others？ The answer is no. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power saw is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further: he must be sure that he has a reasonable answer to his question and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the condition permit. What works under one set of conditions at one time mustwork under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was latter tested through investigation. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurement. Then the measurements are used to make mathematical calculations that may test his investigations.

certain general ideas for granted, and call them common sense. We should learn that other people have held quite different ideas, and that our own have started as very original guesses of philosophers.

A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the questions on which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and another from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun, and is reflected into our eyes. We don't know in much detail how the changes in our eyes give rise to sensation. But there is every reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty fully cleared up.

But if our descendants know the answers to these questions and others that perplex us today, there will still be one field of which they do not know, namely the future. However exact our science; we cannot know it as we know the past. Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason why Marx and Engels quite rightly wrote to many philosophical problems that interested their contemporaries.

But we have got to prepare for the future, and we cannot do so rationally without some philosophy. Some people say we have only got to do the duties revealed in the past and laid down by religion, and god will look after the future. Others say that the world is a machine and the course of future events is certain, whatever efforts we may make. Marxists say that the future depends on ourselves, even though we are part of the historical process. This philosophical view certainly does inspire people to very great achievements. Whether it is true or not, it is powerful guide to action.

We need a philosophy, then, to help us to tackle the future. Agnosticism easily becomes an excuse for laziness and conservatism. Whether we adopt Marxism or any other philosophy, we cannot understand it without knowing something of how it developed. That is why knowledge of the history of philosophy is important to Marxists, even during the present critical days.

What is the main idea of this passage？

A．The argument whether philosophy will ultimately be solved by science or not.

B．The importance of learning philosophies, especially the history of philosophy.

C．The difference between philosophy and science.

D．A discuss about how to set a proper attitude towards future.

munication. Generally, this expression of thoughts and feelings has been in the form. of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words and ideas. Tourists, the deaf, and the mute have had to resort to this form. of expression. Many of these symbols of whole words are very picturesque and exact and can be used internationally; spelling, however, cannot. Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally.. A wink can be a way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the head indicates a negative reaction.

Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, ,Morse code, and smoke signals. Road maps and picture signs also guide, warn, and instruct people. While verbalization is the most common form. of language, other systems and techniques also express human thoughts and feelings.

pain.

To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.

Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.

But there is a way to handle pain. Look at the Indian fakir(行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain; This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.

The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little, it helps us to accept the pain. By staying relaxed,' and by treating the pain as an interesting sensation, we' can handle the pain without falling apart. After all; although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.

26. The passage is mainly about______.

A) how to stiffer pain

B) how to avoid pain

C) how to handle pain

D) how to stop pain

and employees. This phenomenon often occurs not just within top management, but also within middle management.

I've seen this isolation phenomenon in many companies. The symptoms are quite apparent: Managers spend a great deal of time talking to themselves and studying operating numbers. They spend precious little time with customers or with employees, trying to understand the system of the business. And when they do spend time with them, they often do not probe deeply into needs, concerns, and opportunities. This phenomenon, often referred to as being" internally focused," can be tremendously insidious.

Although the need for understanding and spending time with customers has been well documented, I find few managers spending time in the field. The benefits of doing so are clear. A visit with your counterparts at customers' distribution centers, for example, not only builds relationships that can prove useful when problems arise, but also uncovers numerous opportunities to enhance your performance and deepen your company's linkage with those customers.

There are many ways to connect with and understand employee perspectives. Some companies have found formal sessions in which senior managers solicit ideas from employees to be very useful. These can be run either as focus groups or as structured discussions.

Managers also should exploit every opportunity to gather organizational knowledge from employees. Some successful managers collect employees' opinions by what often is referred to as" managing by walking around" or the" 10-minute cup of coffee. "They may, for example, go to employees' offices and solicit, their opinions. Or at lunch or when they take a cup of coffee, they" mix with the troops" and solicit their input.

Rather than talk about the latest game, you can solicit employees' ideas by asking questions like: What are you working on？ How's it going？ What's good about our organization？ What could be better？ How could we better serve our customers or improve our processes？ What do you think we Should be doing differently？

You'll be surprised at how valuable a" 10-minute cup of coffee" together with a brief conversation with an employee can be. It will make you a more effective manager.

What is the common problem in management？

A．Infrequent contact with customers and employees.

B．Managers spend little time on study.

C．Managers do not know their employees well.

D．Managers lack of experience.
