“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days！”
These are the kinds of statements used in magazine，newspaper，radio and television ads，promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs，slim the face，smooth wrinkles，or in some other way to add to beauty or desirability.
Often such products are nothing more than moneymaking things for their promoters. The results they produce are questionable，and some are dangerous to health.
To understand how these products can be legally promoted to the public，it is necessary to understand something of the laws covering their regulation. If the product is a drug，FDA(Food and Drug Administration)can require proof under the Food，Drug，and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device，FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health，FDA can request the producer or distributor to remove it from the market voluntarily， or it can take legal action，including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor，which had been sold for reducing the waistline (腰围). The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously，most of the devices on the market have never been the subject of court proceedings(法律诉讼)，and new devices appear continually. Before buying，it is up to the consumer to judge the safety or effectiveness of such items.It can be inferred that the ads mentioned in the text are________.
| A．objective | B．costly | C．unreliable | D．illegal |

I came to study in the United States a year ago .Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.
After the accident, my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I’d have to have a good lawyer. And only a good doctor can help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him.
But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.
My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss him. And he made me pay him $770.

Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them. More than that, though, he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凯亚巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce. In 1882 a visitor noted, "We, who ... have wandered through its forests and parks, have come to regard it as the most enchanting region it has ever been our privilege （特权） to visit.” This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time, 6,250 mountain lions, wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924, there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饥饿） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000. The destruction of the environment of the Kaibab resulted from
| A．interfering with natural cycle of forest life |
| B．turning the forest into cultivated land |
| C．forest fires caused by man’s carelessness |
| D．cutting the trees for building materials |
"Engelmann spruce"（Para. 2） is most likely the name of .
| A．an animal | B．a tree | C．a mountain | D．a game |
The number of the deer in the Kaibab had increased enormously in years’ time.
| A．25 | B．6 | C．12 | D．18 |
Years later, large numbers of deer in the Kaibab died mainly because of .
| A．the cold | B．the organized kill |
| C．the poor management | D．the shortage of food |
