How they work no one knows. But the brain rules the body in many subconscious ways, including its control of the body's major hormones and its subtle influence over the immune system. So it's possible that, in ways yet unknown, expectations about health or disease are sometimes translated in to a bodily reaction that fulfils them. The power of these effects is hard to overstate.
A rule of thumb is that 30 percent of patients in the placebo half of a drug trial (i. e. those who unknowingly receive a dummy pill instead of the real thing) will experience all improvement in symptoms. But the proportion may be much higher. Just like real drugs, placebo pills can produce stronger effects in larger doses. Patients will report greater relief when given a larger pill, or two dummy capsules instead of one.
Doctors' expectations also contribute to the awesome power of the placebo effect. In a study of tooth extraction, patients were given either a painkiller or sham drugs. Some dentists were assigned to give either drug, without knowing which, but other dentists knew they would be giving only sham drugs. The patients whose dentists thought they had at least a 50-50 chance of giving a painkiller suffered significantly less pain. Presumably, doctors transmit their expectations to the patient through subtle cues, often without knowing they are doing so.

A.only exist in people's imagination
B.were medicines used by Latin people

D.are hated by both doctors and patients
A recent controversy as to whether labels on prepared foods should educate or merely inform. the consumer is over, and a consumer group got its way. The group had maintained that product labels should do more than simply list how many grams of nutrients a food contains. Their contention was that labels should also fist the percentage of a day's total nutrients that the product will supply to the consumer, because this information is essential in planning a healthy diet.
A government agency disagreed strongly, favoring label that merely informs the consumer, in other words, a label that only lists the contents of the product. The agency maintained that consumers could decide for themselves if the food is nutritious and is meeting their daily needs.
The consumer group, in supporting its case, had cited a survey in which shoppers were shown a food label, and were then asked if they would need more or less of a certain nutrient after eating a serving of this product. The shoppers were not able to answer the questions easily when they were not given a specific percentage.
This study, and others helped get the new regulation passed, and now food products must have the more detailed labels.

A.Less than 68%.
B.About 50%.
C.Over 70%.
D.Around 45%.
In my fridgeless Fifties childhood, 1 was fed well and healthy.The milkman came every day, the grocer, the butcher (肉商), the baker, and the ice-cream man delivered two or three times each week.The Sunday meat would last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes.Nothing was wasted, and we were never troubled by rotten food.Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.
The invention of the fridge contributed comparatively little to the art of food preservation.Many well-tried techniques already existed -- natural cooling, drying, smoking, salting, sugaring, bottling...
What refrigeration did promote was marketing --- marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.
Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary.Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house -- while outside, nature provides the desired temperature free of charge.
The fridge's effect upon the environment has been evident, while its contribution to human happiness has been not important.
