Today, cigarette smoking is a common habit. About fortythree percent of the adult men and

Today, cigarette smoking is a common habit. About forty-three percent of the adult men and thirty-one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to see that millions of people have given up smoking.

It is a fact that men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is 24-44.

Income, education, and occupation all play a part in determining a person's smoking habit. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well-educated man with a higher income smoked at all, he is likely to smoke more packs of cigarettes per day.

The situation is somewhat different for women. (80) There are slightly more smokers among women with higher family income and higher education than among the lower income and lower educational groups. These more highly .educated women tend to smoke more heavily.

Among teenagers the picture is similar. There are fewer teenaged smokers from upperincome, well-educated families, and fewer from families living in farm areas. Children are most likely to start smoking if one or both of their parents smoke.

What do we know from the first paragraph？

A．More and more people take up the habit of smoking.

B．There are more smoking women than smoking men in the U. S. Ａ.

C．It is good news that more people have given up smoking.

D．The U. S, has more smoking people than any other country.

It is hardly necessary for me to cite all the evidence of the depressing state of literacy

. These figures from the Department of Education are sufficient- 27 million Americans cannot read at all, and a further 35 million read at a level that is less than sufficient to survive in our society.

But my own worry today is less that of the overwhelming problem of elemental literacy than it is of the slightly more luxurious problem of the decline in the skill even of the middle-class reader, of his unwillingness to afford those spaces of silence, those luxuries of domesticity and time and concentration, that surround the image of the classic act of reading, it has been suggested that almost 80 percent of America's literate, educated teenagers can no longer read without an accompanying noise (music) in the background or a television screen flickering at the corner of their field of perception. We know very little about the brain and how it deals with simultaneous conflicting input, but every common-sense intuition suggests we should be profoundly alarmed. This violation of concentration, silence, solitude goes to the very heart of our notion of literacy; this new form. of part-reading, of part-perception against background distraction, renders impossible certain essential acts of apprehension and concentration, let alone that most important tribute any human being can pay to a poem or a piece of prose he or she really loves, which is to learn it by heart. Not by brain, by heart; the expression is vital.

Under these circumstances, the question of what future there is for the arts of reading is a real one. Ahead of us lie technical, psychic, and social transformations probably much more dramatic than those brought about by Gutenberg, the German inventor in printing. The Gutenberg revolution, as we now know it, took a long time; its effects are still being debated. The information revolution will touch every fact of composition, publication, distribution, and reading. No one in the book industry can say with any confidence what will happen to the book as we've known it.

The picture of the reading ability of the American people, drawn by the author, is ______.

A．rather bleak

B．fairly bright

C．very impressive

D．quite encouraging

第5题

The study of philosophies should make our own ideas flexible. We are all of us apt to take

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.

I know when the snow melts and the first robins （知更鸟) come to call, when the laughter o

I know when the snow melts and the first robins (知更鸟) come to call, when the laughter of children returns to the parks and playgrounds, something wonderful is about to happen.

Spring cleaning.

I'll admit spring cleaning is a difficult notion for modern families to grasp. Today's busy families hardly have time to load the dishwasher, much less clean the doormat. Asking the family to spend the weekend collecting winter dog piles from the melting snow in the backyard is like announcing there will be no more Wi-Fi. It interrupts the natural order.

"Honey, what' say we spend the weekend beating the rugs, sorting through the boxes in the basement and painting our bedroom a nice lemony yellow？" I say.

"Can we at least wait until the NBA matches are over？" my husband answers.

But I tell my family, spring cleaning can 't wait. The temperatures has risen just enough to melt snow but not enough for Little League practice to start. Some flowers are peeking out of the thawing ground, but there is no lawn to seed, nor garden to tend. Newly wakened from our. winter's hibernation (冬眠), yet still needing extra blankets at night, we open our windows to the first fresh air floating on the breeze and all of the natural world demanding "Awake and be clean!".

Biologists offer a theory about this primal impulse to clean out every drawer and closet in the house at spring's first light, which has to do with melatonin, the sleepytime hormone (激素) our bodies produce when it's dark. When spring's light comes, the melatonin diminishes, and suddenly we are awakened to the dusty, virus-filled house we've been hibernating in for four months.

I tell my family about the science and psychology of a good healthy cleaning at spring's arrival. I speak to them about life's greatest rewards waiting in the removal of soap scum from the bathtub, which hasn't been properly cleaned since the first snowfall.

"I'll do it," says the eldest child, a 21-year-old college student who lives at home.

"You will？ Wow!" I exclaim.

Maybe after all these years, he's finally grasped the concept. Maybe he's expressing his rightful position as eldest child and role model. Or maybe he's going to Florida for a break in a couple of weeks and he's being nice to me who is the financial-aid officer.

No matter. Seeing my adult son willingly cleaning that dirty bathtub gives me hope for the future of his 12-year-old brother who, instead of working, is found to be sleeping in the seat of the window he is supposed to be cleaning.

"Awake and be clean!" I say.

According to the passage, ". . . spring cleaning is a difficult notion for modern families to grasp" means that spring cleaning______.

A．is no longer an easy practice to understand

B．is no longer part of modern family life

C．requires more family members to be involved

D．calls for more complicated skills and knowledge
