I think the modern fountain or ballpoint pen is one of the greatest contributions ever made to __16__ happiness.

A
Utopia is a perfect place. It is a place without war, hunger, poverty, or crime. It is a place where the people work together and share. There is no money in Utopia because the people do not need money. They do not have personal possessions because everything belongs to everyone. All of the people are equal in Utopia, and the laws are all fair.
Utopia is not a new place. Plato, the ancient Greek philosopher, described a perfect society in his famous dialogue The Republic. In Plato’s Republic, philosophers were the kings, and every person had a place in the society. In 1516, Sir Thomas More wrote about an island in the Pacific Ocean where everything was perfect. He named the island
“Utopia”. In 1602, Tommaso Campanella wrote. The City in the Sun about a perfect community on the island of Ceylon (now Sri Lanka ) ; and in 1872, Samuel Butler wrote a novel about a perfect country which he named “Erewhon”. “Utopia” is a Greek word that means “not a place”, and “Brewton” is the English word “nowhere” spelled backwards.
Utopia is a perfect place, but it is not a real place. Most ‘real’ Utopias last only a short time. This is because everyone wants to live in it, but no one knows how to make it work. As a result, when we say something is ‘Utopia’ today, we mean that it is a good idea, but it is not realistic.
Which of the following would be the best t title for this passage
a. Utopia b. A Good Idea
c. A Perfect Place d. The Utopian Community
The reason why there are no personal possessions in Utopia is that ______.
everything belongs to everyone
the people don’t need money
all of the people are created equal
the laws are reasonable
The idea of Utopia was suggested by ________.
a. Plato
b. Utopian people
c. Tommaso, Samuel Butler and Sir Thomas More
d. A and B
All these Utopian communities that are mentioned in this passage were established in _____.
a. American b. Indiana c. America and India d. Greek
According to the passage, most ‘real’ Utopias last only a short time because _______.
no one wants to be a leader
no one knows how to make a perfect society
it is difficult to collect money
everyone wants to live in Utopia
B
The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is not sure way of telling how much you can drink before you reach this limit. It varies with each person depending on our weight, your sex, if you’ve just eaten and what sort of drinks you’ve had. Some people might reach their limit after only about three standard drinks.
In fact, your drinking ability can be affected by just one or tow drinks. Even if you’re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.
It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening you might find that your driving ability is still affected the next morning, or you could even find that you’re still over the legal limit. In addition, if you’ve had a few drinks at lunchtime, another one or tow drinks in the early evening may well put you over the legal limit.
In a test with professional drivers, the more alcoholic drinks they had had the more certain they ere that they could drive a test course through a set of moveable posts and the less able they were to do it!
So the only way to be sure you’re safe is not to drink at all.
Alcohol is a major cause of road accidents. One is three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More than half of people stopped by the police to take a breath analyzer test have a blood alcohol concentration of more than twice the legal limit.
It is important to remember that driving after you’ve been drinking doesn’t just affect you. If you’re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure.
Which of the following statements is NOT true
Three standard drinks may cause some people to reach the legal limit.
There is no sure way of telling how much you can drink before you reach the legal limit.
The legal limit for driving after drinking is 0.008 gm of alcohol in 100 milliliters of blood.
The amount of alcohol a person can drink before reaching legal limit is the same for different people.
If the police think that you have been drinking from the way you are driving, you’ll possibly _______.
a. be fined b. receive a severe punishment
c. be taken to court by the police d. feel guilt
We may infer that even a professional driver will find hard to pass through a set of moveable posts if he drinks _______.
a. heavily b. a little c. every day d. occasionally
This passage indicated that ________.
a driver who does not take any alcohol will not die in road accidents
those who drink must be killed
more young men die in drink-related accidents than in any other way
one is three of the drivers often drinks a lot
One of the writer’s purposes in writing the passage is to tell you that _______.
young men should never drive quickly
driving after drinking may put many lives at risk
safe drinking is impossible
the manner of drinking is meaningless
C
In science the meaning of the word “explain” suffers with civilization’s every step in search of reality. Science cannot really explain electricity magnetism, and gravitation; their effects can be measured and predicted （预测）, but of their nature no more is known to the modern scientist than to Thales who first speculated on the electrification of amber(琥珀). Most present physicists reject the notion that man can ever discover what these mysterious forces “really” are. Electricity, Bertrand Russell says, “is not a thing, it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell.” Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, so one can deduce that objects fall to the ground because that’s where they belong, and smoke goes up because that’s where it belongs. The goal of Aristotelian science was to explain why thins happen. Modern science was born when Galileo began trying to explain how things happen and thus originated (使成起源 )the method of controlled experiment which now forms the basis of scientific investigation.
From this passage we learn that the effects of electricity, magnetism and gravitation can be measured and _____.
a. foreclosed b. prearranged c. forecast d. precl
Most modern physicists agree with the idea that _______.
man can not discover what these mysterious forces “really” are
man can discover what these mysterious forces “really” are
man can discover everything in the universe
man can not discover the nature of electrification
The principle that everything in the universe has its proper place is favored by _________.
a. St. Paul b. Bertrand Russell c. Galileo d. Aristotle
The aim of Aristotle’s natural science is to explain _______.
a. the method of controlled experiment b. the search of reality
c. how things happen d. why things happen
According to the passage, which of the following is NOT true
Bertrand Russell’s concept of electricity is not in harmony( 和谐，协调 ) with the basis of scientific investigation.
Bertrand Russell’s concept of electricity is in harmony with the basis of scientific investigation.
Aristotle’s natural science most influence scientific thought for two thousand years.
Thales first guessed the electrification of amber.
D
Between now (June) and Labour Day, millions of Americans will offer up their bodies to the sun’s rays. A an indicates health and beauty, and most sun worshippers will sacrifice ( 牺牲 ) lot to achieve it including themselves. With each hour, the sun’s ultraviolet (紫外线 ) radiation produces irreversible ( 不可逆的) damage, hastening the development of unsightly wrinkles. And with each year on the beach or rooftop, the sunbather increases his risk of getting skin cancer.
Skin cancer is by far the most common form of cancer. An estimated 400,000 new cases will be detected this year in the US, and almost all of them can be blamed on overexposure to the sun. Fortunately, most of these cancers are highly curable. But they can be disfiguring and take time to treat. For that reason, sun worshippers should treat deity with a good deal of awe.
Sunburn, of course, is the initial danger posed by UV radiation. Prolonged exposure to UV, however, interferes with the production of collagen fibres in the dermis, causing the skin to lose elasticity and creating premature wrinkles. Further damage of the dermis deprives the epidermis of nutrition and causes it to become thin and dry.
Cancer is UV’s final insult. Short-wave radiant energy, especially from the UV-B band, breaks the strands of DNA. Enzymes works constantly to rearrange the DNA into proper sequence, but with repeated UV exposure, the repair process may eventually break down. Then DNA may produce a colony of cancer cells.
But skin cancer may be avoided with a good dose of common sense. People with fair skin and blue eyes who burn easily stand the highest risk. Special danger spots are the parts of the body most constantly exposed to the sun, such s the cheeks, nose, lower lip and the ears. People who have already had one skin-cancer growth stand a greatly increased chance of developing others. People are recommended avoiding the sun when it is most intense between 11am and 3 pm. Anyone who insists on sunbathing should use a good sun screen. These lotions contain chemicals that block out the burning UV-B radiation while permitting the tanning rays to reach the skin.
According to the passage, overexposure to the sun may result in ________.
a. the wrinkles that cannot be seen b. the skin cancer
c. all kinds of sacrifices d. healthful beauty
The word “deity” in the second paragraph refers to ________.
a. something mysterious b. the skin cancer
c. the sun d. overexposure to the sun
Which of the following comes first as a possible damage by UV radiation
a. Sunburn b. The loss of skin elasticity.
c. Dryness of epidermis d. The damage of dermis
Why does the repair process of the DNA may finally fail
Because short-wave radiant energy breaks the strands of the DNA.
Because the DNA may produce a colony of cancer cells.
Because enzymes work to rearrange the DNA into a new order.
Because the patient is exposed to UV from time to time.
The last paragraph of the passage mainly discuss _______.
the treatment of the cancer
the prevention of the skin cancer
the parts of the body where cancer is most likely to develop
the lotions that work best in fighting against the skin cancer

Generation Gap
These days the generation gap is a hot social issue. A generation gap refers to the difference in point of view and the lack of understanding between the young and old people. It’s something that exists everywhere in the world.
Different age groups react differently to new things and have different attitudes to traditional customs and beliefs. Because our way of thinking is formed at a young age when we are easily affected by society, young people look to the future while the elderly prefer thinking about the good old days. Young people like being independent. However, sometimes their behaviours hurt the old very much. The older generation’s way of thinking also often lags behind the young one.
If we don’t deal with the problem properly, the gap will get bigger and affect the relations between the young and old in our society. While the young are asking for understanding, the old could also do with some. Understanding should come from both.

But skin cancer may be avoided with a good dose of common sense. People with fair skin and blue eyes who burn easily stand the highest risk. Special danger spots are the parts of the body most constantly exposed to the sun, such s the cheeks, nose, lower lip and the ears. People who have already had one skin-cancer growth stand a greatly increased chance of developing others. People are recommended avoiding the sun when it is most intense between 11am and 3 pm. Anyone who insists on sunbathing should use a good sun screen. These lotions contain chemicals that block out the burning UV-B radiation while permitting the tanning rays to reach the skin.
According to the passage, overexposure to the sun may result in ________.
a. the wrinkles that cannot be seen b. the skin cancer
c. all kinds of sacrifices d. healthful beauty
The word “deity” in the second paragraph refers to ________.
a. something mysterious b. the skin cancer
c. the sun d. overexposure to the sun
Which of the following comes first as a possible damage by UV radiation
a. Sunburn b. The loss of skin elasticity.
c. Dryness of epidermis d. The damage of dermis
Why does the repair process of the DNA may finally fail
Because short-wave radiant energy breaks the strands of the DNA.
Because the DNA may produce a colony of cancer cells.
Because enzymes work to rearrange the DNA into a new order.
Because the patient is exposed to UV from time to time.
The last paragraph of the passage mainly discuss _______.
the treatment of the cancer
the prevention of the skin cancer
the parts of the body where cancer is most likely to develop
the lotions that work best in fighting against the skin cancer

Generation Gap
These days the generation gap is a hot social issue. A generation gap refers to the difference in point of view and the lack of understanding between the young and old people. It’s something that exists everywhere in the world.
Different age groups react differently to new things and have different attitudes to traditional customs and beliefs. Because our way of thinking is formed at a young age when we are easily affected by society, young people look to the future while the elderly prefer thinking about the good old days. Young people like being independent. However, sometimes their behaviours hurt the old very much. The older generation’s way of thinking also often lags behind the young one.
If we don’t deal with the problem properly, the gap will get bigger and affect the relations between the young and old in our society. While the young are asking for understanding, the old could also do with some. Understanding should come from both.
