When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction and find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country may be at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives and ensure that the disease will not spread.
The process of vaccination allows the patient’s body to develop immunity to the virus or disease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak or dead strain of the disease is actually injected into the patient in a controlled environment, so that his body’s immune system can learn to fight the invader properly. Information on how to penetrate the disease’s defenses is transmitted to all elements of the patient’s immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped and trained to deal with it, having already done so before.
There are ers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much for the body to handle, resulting in the immune system succumbing, and, therefore, the patient’s death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers. Approximately 1 in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3000 Americans would be left dead.
Fortunately, the smallpox virus was considered eradicated in the early 1970’s, ending the mandatory vaccination of all babies in America. In the of a reintroduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.
What does the example of the Smallpox Vaccine illustrate

A.
A possible negative outcome of administering vaccines.
B.
The practical use of a vaccine to control an epidemic disease.
C.
A method by which vaccines are employed against the disease.
D.
The effectiveness of vaccines in curing certain disease.

【单选题】The buying of Alaska was first called () A.a foolish thing B.Seward’s Fooly C.Johnson’s Fooly D.President’s Foolishness

A.
Alaska, which was called Russian America before it was sold to the United States of America, joined the union as the forty-ninth state in 1959.
B.
Alaska is now the largest of all the 50 states of the United States.
C.
It was in 1867 that President A. Johnson’s Secretary of State (国务卿) ,Seward bought Alaska from the Russians at a cost of 7.2 million. The buying of the huge northern land mass seemed at first something foolishly done. Not only was Alaska difficult to reach, but it was also hard to live in, and it appeared to have no importance in time of war. Besides, there are volcanoes there as Alaska lies on the Pacific "ring of fire" (火山带). In Alaska large treeless areas are covered with snow all the year. For these reasons the buying of Alaska was called "Seward’s Fooly" at that time.
D.
However, in 1896 gold was found in Alaska, and people poured into the land quickly. Since then other important natural resources were discovered, including oil. Soon people changed their thinking about "Seward’s Fooly" . But most people visit Alaska in order to see the endless beauty of nature that the northern land discloses to them. For instance, there are about 11,000 islands in Alaska. And in a certain area of Alaska the sun does not set for 82 days every year.

Also, (19) of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become (20) over the whole eye.
