Marketing specialists study______.

The pleasures which a movie offers to our eyes have been paid for with the loss of sight of a man whose name is hardly known outside the annals of science—Joseph Plateau, a Belgian professor, born in Brussels in 1801. He studied the mechanism of sight, beginning a series of most dangerous experiments at the age of 28 by staring into the sun for 25 seconds to see what the effect on his eyes would be. He was blind for nearly a month. But he went on experimenting, increasing the length of time during which he looked into the sun, knowing that in the end this would cost him his sight. At the age of 42 he was completely and incurably blind: the sun had destroyed the retina(视网膜) of his eyes. But he continued to work as well as he could until he died at the age of 82. Science profited enormously from his research. He studied the so-called "inertia of the eye (视觉暂留 )" which makes a picture remain on the retina for about one-sixth of a second after it has disappeared from our vision. This means that, if we see a succession of individual pictures each of which appears only for a fraction of a second, they " overlap" in our brain: and if they show consecutive phases of movement, that movement will appear to us to be continuous.Plateau’ s experiments were the first step leading to the invention of______.

A．eyeglasses
B．telescopes
C．bifocals
D．motion pictures

Specialists in marketing have studied how to make people buy more food in a supermarket. They do all kinds of things that you do mot even notice. For example, the simple, ordinary food that everybody must buy, like bread, milk, flour, and vegetable oil, is spread all over the store. You have to walk by all the more interesting and more expensive things in order to find what you need. The more expensive food is in packages with bright colored pictures. This food is placed at eye level so you see it and want to buy it. The things that you have to buy anyway are usually located on a higher or lower shelf. However, candy and other things that children like are on lower shelves. One study showed that when a supermarket moved four products from floor to eye level, they were sold 78 percent more. Another study showed that for every minute a person is in a supermarket after the first half hour, she or he spends $50. If someone stays forty minutes, the supermarket has an additional $5. So the store has a comfortable temperature in summer and winter, and it plays soft music. It is a pleasant place for people to stay and spend more money. Some stores have red or pink lights over the meat so the meat looks redder. They put light green paper around lettuce (生菜) and put apples in red plastic bags. So be careful in the supermarket. You may go home with a bag of food you were not planning to buy. The supermarket, not you, decided you should buy it.Marketing specialists study______.

A．plants suitable for human needs
B．how to build shelves
C．method of selling more products
D．how to own supermarkets

We are all interested in equality, but while some people try to protect the school examination system in the name of equality, others, still in the name of equality, want only to destroy it. Any society which is interested in equality of opportunity and standards of achievement must regularly test its pupils. The standards may be changed—no examination is perfect—but to have no tests or examinations would mean the end of equality and of standards. There are groups of people who oppose this view and who do not believe either in examinations or in any controls in school or on teachers. This would mean that everything would depend on luck since every pupil would depend on the values and the purpose of each teacher. Without examinations, employers will look for employees from the highly respected schools and from families known to them—a form of favoritism will replace equality. At the moment, the bright child from an ill-respected school can show certificates to prove he is suitable for a job, while the lack of a certificate indicates the unsuitability of a dull child attending a well-respected school. This defense of excellence and opportunity would disappear if examinations were taken away, and the bright child from a poor family would be a prisoner of his school’ s reputation, unable to compete for employment with the child from the favored school. The opponents of the examination system suggest that examinations are an evil force because they show differences between pupils. According to these people, there must be no special, different academic class. They have even suggested that there should be no form of difference in sport or any other area: all jobs or posts should be filled by unsystematic selection. The selection would be made by people who themselves are probably selected by some computer.The word "it" in paragraph 1 refers to______.

A．equality
B．the society
C．the school
D．the examination system
