Passage 5
C. was named the Eijkman vitamin
Yinlan looked at the people sitting around the table and smiled with satisfaction. Everyone in her family was there — her children, her grandchildren, and her new great-grandson, just one month old. Her whole family had come to celebrate the Harvest Moon Festival (节日).
Yinlan had grown up in China, but she and her family now lived in San Francisco, California. Although they lived in the United States, Yinlan's family celebrated the Harvest Moon Festival just as Yinlan had in China. Then, if the sky was clear, they always walked outside to admire the full moon. Tonight there was not a cloud in the sky, and the full moon shone brightly. Yinlan suggested that they all go outside. Her grandson helped her up from her chair. As Yinlan and her grandson walked toward the door, she held on to his arm and leaned against him for support. Yinlan was 86 years old. She had not been well the past few months, and her family noticed that she seemed weak.
Two days after the Harvest Moon Festival, Yinlan died peacefully in her sleep. Her family was sad but at the same time grateful. They felt happy that they had been able to celebrate the Harvest Moon Festival with her one last time. Everyone said it was remarkable that Yinlan had died just two days after the holiday.

Actually, the timing of Yinlan's death was not remarkable at all. Recently sociologists（社会学家）studied the death rate among elderly Chinese women in California. They discovered that the death rate drops 35 percent before the Harvest Moon Festival and then rises 35 percent. Sociologists believe that these changes in death rate show the mind's power over the body. The Harvest Moon Festival, when families gather, is important to elderly Chinese women. Apparently some women are able to postpone（推迟）their deaths so that they can celebrate the festival one last time.
Sociologists also studied the death rate of elderly Jewish men around the time of Passover, a Jewish holiday. They discovered the same phenomenon. Passover is a Jewish religious holiday that is a family holiday as well. On the first two days of Passover, families gather in their homes for a ceremony（仪式）. It is an important event for elderly Jewish men — so important that some men postpone their deaths until after Passover.
The idea that people can postpone the time of their deaths is not new. Many families tell stories of a relative who held on to life until after an important event. They tell of grandmother who died after the birth of a grandchild, a grandfather who died after his 92nd birthday party. The stories people tell, however, are just that: stories. They are not proof that people can postpone their deaths. The sociologists' work is important because the sociologists studied facts, not stories. The facts — the drop and rise in death rates — prove that people really can postpone their deaths. One famous person who may have postponed his death was Thomas Jefferson. Thomas Jefferson wrote the Declaration of Independence, one of the most important U.S. documents. The Declaration of Independence was signed on July 4, 1776. Thomas Jefferson died exactly 50 years later, on July 4, 1826. He died after asking his doctor, \
Historians have always thought that Jefferson's death on the Fourth of July was a remarkable coincidence（巧合）. It now seems quite possible that the timing of Jefferson's death was no coincidence at all. (597 words)

Passage 6
A strict vegetarian is a person who never in his life eats anything derived from animals. The main objection to vegetarianism（素食主义）on a long-term basis is the difficulty of getting enough protein — the body-building element in food. If you have ever been without meat or other animal foods for some days of weeks (say, for religious reasons) you will have notice that you tend to get physically rather weak. You are glad when the fast（禁食）is over and you get your reward of a delicious meat meal.
Proteins are built up from about twenty food elements called \氨基酸) , which are found more abundantly in animal protein than in vegetable protein. This means you have to eat a great deal more vegetable than animal food in order to get enough of these amino-acids. A great deal of the vegetable food goes to waste in this process and from the physiological（生理学的）point of view there is not much to be said in favor of life-long vegetarianism.
The economic side of the question, though, must be considered. Vegetable food is much cheaper than animal food. However, since only a small proportion of the vegetable protein is useful for body-building purposes, a consistent vegetarian, if he is to gain the necessary 70 grams (克) of protein a day, has to consume a great bulk of food than his digestive organs can comfortably deal with. In fairness, though, it must be pointed out that vegetarians claim they need far less than 70 grams of protein a day. (276 words)

A. about twenty different foods B. about twenty different vegetables C. various fats and sugars D. about twenty different amino-acids 4. Physiologically, life-long vegetarianism may not be good because ______. A. it makes people very thin
