(D)
You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.You can see the book because_______.
| A．your eyes are close to it | B．it reflects some of the sunlight |
| C．it has light of its own | D．your eyesight can get to it |
The underlined word “luminous” means_______.
| A．visible | B．all colors | C．giving off light | D．sunlight |
________ have light of their own.
| A．The sun and the moon | B．The stars and the earth |
| C．The sun and the stars | D．The moon and the earth |
Which of the following is true?
| A．All the things you can see give off light. |
| B．Light from the book is much shorter than that from the moon. |
| C．The moment you open your eyes the light from the book travels to your eyes. |
| D．Light travels so fast that there is no time for you to read. |
This article is probably from _________ .
| A．a science magazine | B．a medical magazine |
| C．a biography | D．a story book. |
Holmes’ Knowledge
His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest（天真的；幼稚的）way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar system.
“You appear to be astonished, ” Holmes said, smiling at my expression. “Now that I do know it I shall do my best to forget it. You see, I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. It is a mistake to think that the little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
“But the Solar System! ” I protested.
“What the deuce is it to me?” he interrupted impatiently.
One morning, I picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. One of the articles had a pencil mark at the heading, and I naturally began to run my eye through it.
Its somewhat ambitious title was “The Book of Life, ” and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. It struck me as being a remarkable mixture of shrewdness and of absurdity. The reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. The writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man’s inmost thought. Deceit, according to him, was impossibility in the case of one trained to observation and analysis. His conclusions were as infallible as so many propositions of Euclid. So startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.
“From a drop of water, ”said the writer, “a logician could infer the possibility of an Atlantic. So all life is a great chain, the nature of which is known whenever we are shown a single link of it. Like all other arts, the science of Deduction and Analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it. ”
This smartly written piece of theory I could not accept until a succession of evidences justified it.What is the author’s attitude toward Holmes?
A Praising. B Critical. C Ironical. D Distaste.What way did the author take to stick out Holmes’ uniqueness?
A By deduction. B By explanation. C By contrast. D By analysis.What was the Holmes’ idea about knowledge-learning?
A Learning what every body learned. B Learning what was useful to you.
C Learning whatever you came across. D Learning what was different to you.What did the article mentioned in the passage talk about?
A One may master the way of reasoning through observation.
B One may become rather critical through observation and analysis.
C One may become rather sharp through observation and analysis.
D One may become practical through observation and analysis.
The Development of Cities
Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern（现代文明之前）era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housed five to six million people.
Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned. It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users. Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand as much as to respond to it. Chicago is a prime example of this process. Real estate（财产）subdivision（细分再分的部分）there proceeded much faster than population growth.With which of the following subjects is the passage mainly concerned?
A Types of mass transportation.
B Instability of urban life.
C How supply and demand determine land use.
D The effect of mass transportation on urban expansion.Why does the author mention both Boston and Chicago?
A To demonstrate positive and negative effects of growth.

C To show mass transportation changed many cities.
D To contrast their rate of growth.According to the passage, what was one disadvantage of residential expansion?
A It was expensive.
B It happened too slowly.
C It was unplanned.
D It created a demand for public transportation.The author mentions Chicago in the second paragraph as an example of a city,
A that is large.
B that is used as a model for land development.
C where the development of land exceeded population growth.
D with an excellent mass transportation system.
Stricter Traffic Law Can Prevent Accidents
From the health point of view we are living in a marvelous（不平凡的）age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of men, women and children on the roads. Man versus the motor-car ! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.
It has been rightly said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They swear, they are ill-mannered and aggressive, willful as two-years-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles so benignly on the motorist and seems to condone his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy tragic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.
It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through stringent annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person’s driving ability. Present drinking and driving laws (where they exist) should be mad much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as to severe if tit results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.The main idea of this passage is
A Traffic accidents are mainly caused by motorists.
B Thousands of people the world over are killed each year.
C The laws of some countries about driving are too lax.
D Only stricter traffic laws can prevent accidents.What does the author think of society toward motorists?
A Society smiles on the motorists. B Huge car parks are built in the cities and towns.
C Victims of accidents are nothing. D Society condones their rude driving.Why does the author say:’ his car becomes the extension of his personality?’
A Driving can show his real self. B Driving can show the other part of his personality.
C Driving can bring out his character. D His car embodies his temper.Which of the followings is NOT mentioned as a way against traffic accidents?
A Build more highways. B Stricter driving tests.
C Test drivers every three years. D raise age limit and lay down safety specifications.The attitude of the author is
A ironical B critical C appealing D militant
While students in Hainan are quite used to clear skies, Beijing teenagers are not so lucky. As another warm winter approaches, the city can expect the normal clouds of smoke caused by air pollution.
But things could start to get better soon. The government is co-operating with a US-based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel vehicles (柴油机) by 40 per cent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them.
“We encourage the development of public transportation. But at the same time we need to reduce pollution from them,” said an official.
Efforts are being made to improve the capital’s environment with tighter controls on emissions (排放). Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed.
Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index (指数) gave just 100 days as good.
“I am glad to see an improvement,” said a Senior 1 boy living in the northwest of Beijing. “Compared to other places, the air quality of Beijing is still worrying though. I hate the pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn’t see a car only metres away from me in frog.”
In early October, the skies were covered by such a thick fog that a display show by the visiting French air force was called off.
Rapid development, industry, traffic fumes (烟) and sandstorms from the desert all contribute to the city’s bad air.The passage is mainly about ________?
| A．a programme to improve Beijing’s air quality |

How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words.
The power of words, then, lies in their association—the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and vulgar. What is the origin of language?
| A．It is unknown. |
| B．It is a matter that is unclear. |
| C．It is a question difficult to answer. |
| D．It is a problem not yet solved. |
Which of the following about a real poet is NOT true?
| A．He is less than a master of words. |
| B．His style is always charming. |
| C．His poem can move men to tears. |
| D．He can express his ideas in words that sing like music. |
Where does the real power of the words come from?
| A．From the words themselves. |
| B．From their characteristics. |
| C．From their peculiarity. |
| D．From their association. |
What is the main idea of the passage?
| A．The importance of choosing words. |
| B．Where the real power of words come from. |
| C．What great writers are like. |
| D．We should learn to choose words carefully. |
