Human wants seem endless. When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, he dreams of country clubs and pleasure boats dance into view.
The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears.
The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. Then a third level appeared. It included such items as cars and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction—the feeding, comfort, safety and transportation of the human body—this level means mental needs for recognition, achievement and happiness. It includes a variety of goods and services many of which could be called “luxury” items. Among them are vacation trips, the best medical care and entertainment. Also included here are fancy foods and the latest styles in clothing.
On the fourth level, a greater percentage of consumers spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level probably would be wants that can be achieved by community action. Consumers may be spending more on taxes and crime. After filling our stomachs, our garages, and our minds, we now may seek to ensure the health and safety to enjoy more fully the good things on the first three levels.
【小题1】According to the passage, man will begin to think about such needs as housing and clothing only when _______

Below is a selection from a popular science book.

If blood is red, why are veins (静脉) blue?

Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

Which works harder, your heart or your brain?

That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

Why do teeth fall out, and why don’t they grow back in grown-ups?

Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.

Do old people shrink as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.

Why does spinning make you dizzy (眩晕的)?

Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not!

Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system. All mammals （哺乳动物）have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet.

If exercise wears you out, how can it be good for you?

Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.

The Gold Coast family holidays are always great fun whether you are from Australia or from abroad. There are beautiful beaches, adventure parks, nature parks and so much more.

         There are so many sights to see here. It is a pity to drive in a car and you’ll miss a great part of it. Australia is home to many animals and birds that can only be seen when moving slowly and going into the areas that they live.

         When you are on a bicycle, you have the advantage of being able to stop whenever you want to see an interesting animal or bird that you have never seen before. It is a quieter mode （方式） of transportation as well, so you might even be able to take a picture. When you are on the beach, you can breathe that clean air and view the beauty of the water and sand. It is a totally different experience from either simply sunbathing or passing it in a car.

         There are many choices of hiring a bicycle to experience the Gold Coast attractions. There are stores that will fit a bike perfectly to your size. These bikes for both adults and children are in many styles and colors to please any taste. If you have ever wanted to try a tandem bike （双人单车）, now is your chance, because they have those too.

 As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it’s not easy to change later in life. Financial experts say that everyone also has his own belief of how to manage his money. According to our different values, experts put us in three catagories---the ant, the cricket(蟋蟀) and the snail.

★ The ant — work first

Just like ants who work heart and soul in summer in order to store food for winter, these people don't care about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when they get old and retire. The ant loves to save, but they could make more out of their money if they were willing to invest in some funds and stocks with low risk.

★ The cricket — fun first

The cricket wants to enjoy everything now and doesn't think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have little savings. When they get old, they might have problems. They should learn to save and buy insurance.

★ The snail — life under pressure

The snail refers to people who make life difficult for themselves. They take big long-term loans(贷款) from the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are not sure they can afford them. This can cause problems in the future. They should plan more carefully.

1.  One’s values may________.

A. be his ways of managing money

B. be his beliefs about society

Technology has been an encouragement of historical change. It acted as such a force in England beginning in the eighteenth century, and across the entire Western World in the nineteenth. Rapid advances were made in the use of scientific findings in the manufacture (制造) of goods, which has changed ideas about work. One of the first changes was that other forms of energy have taken the place of human power. Along with this came the increased use of machines to manufacture products in less time. People also developed machines that could produce the same parts for a product: each nail was exactly like every other nail, meaning that each nail could be changed for every other nail. This means that goods could be mass production, although mass production required breaking production down into smaller and smaller tasks.

Once this was done, workers no longer started on the product and labored to complete it. Instead, they might work only one thousandth of it, other workers completing their own parts in certain order. There is nothing strange about this manufacturing work by today's standards. Highly skilled workers were unable to compare with the new production techniques, as mass production allowed goods of high standard to be produced in greater number than could ever be done by hand. But the skilled worker wasn't the only loser, the common workers lost too. Similar changes forced farmer away. The increased mechanization (机械化) of agriculture freed masses of workers from ploughing the land and harvesting its crops. They had no choice but to stream toward the rapidly developing industrial centers. Increasingly, standards were set by machines. Workers no longer owned their own tools, their skill was no longer valued, and pride in their work was no longer possible. Workers fed, looked after and repaired the machines that could work faster than humans at greatly reduced cost.

1.In this passage, which of the following is NOT considered as a change caused by the use of scientific findings in the production of goods?

A．Other forms of energy have taken the place of human power.

B．The increased exploitation (剥削)of workers in the 19th century.

C．The increased use of machines to make products in less time.

D．The use of machines producing parts of the same standard.

A．each nail could be taken the place of by every other nail

B．each nail was exactly like every other nail

C．producing tasks became smaller and smaller

D．goods could be mass produced

3.According to the writer, highly skilled workers ______

A．completely disappeared with the coming of the factory system

B．were dismissed(解散) by the boss

C．were unable to produce goods of high standard

D．were unable to produce fine goods at that same speed as machines

4.According to the passage, what did the farmers have to do with the coming of mechanization of agriculture?

A. Many of them had to leave their farmland for industrial centers.

B. They stuck to their farm work.

C. They refused to use machines.

D They did their best to learn how to use the machines.
