第一篇

A study that will cost $ 3.2 billion and last more than two decades to track the health of 100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.

Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.

The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.

Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.

Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion.

"We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation's health care costs," Dr. Duane Alexander, who heads the NIH 's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.

The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.

Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.

The people taking part will be from rural, urban and suburban areas, from all in- come and educational levels and from all racial groups, the NIH said.

The aim of the study is to find new ways to______.

A. conduct research

B. track public health

C. prevent or treat illness

D. speed up development

第一篇

Last Fourth of July, Pete, a 14-year-old boy, was enjoying the lit-up skies and loud booms from the fireworks being set off in his neighborhood. Suddenly, the evening took a terrible turn. A bottle rocket shot into his eye, immediately causing him terrible pain. His family rushed him to the emergency room for treatment. As a result of the injury, Pete developed glaucoma and cataracts. Today, Pete has permanent vision loss in his injured eye because of his bottle rocket injury.

June is Fireworks Eye Safety Awareness Month, and through its Eye Smart campaign the American Academy of Ophthalmology wants to remind consumers to leave fireworks to professionals. "There is nothing worse than a Fourth of July celebration ruined by someone being hit in the eye with a bottle rocket," said Dr. John C. Hagan, clinical correspondent for the Academy and an ophthalmologist at Discover Vision Centers in Kansas City. "A safe celebration means letting trained professionals handle fire- works while you enjoy the show."

According to the U. S. Consumer Product Safety Commission, more than 9,000 fireworks related injuries happen each year. Of these, nearly half are head-related in- juries, with nearly 30 percent of these injuries to the eye. One-fourth of fireworks eye injuries result in permanent vision loss or blindness. Children are the most common victims of firework abuse, with those fifteen years old or younger accounting for 50 percent of fireworks eye injuries in the United States. Dr. Hagan estimates that his practice sees more than 30 injuries each year from fireworks.

Even fireworks that many people consider safe represent a threat to the eyes. For children under the age of five, apparently harmless sparklers account for one-third of all fireworks injuries. Sparklers can bum at nearly 2,000 degrees Fahrenheit.

What happened to Pete last Fourth of July？

A. He was burned in a house fire.

B. He was caught in a rain.

C. He was injured in a fight.

D. He was hit in the eye.

Stanford University

1. Stanford University, famous as one of northern California&39;s several institutions of higher learning, is sometimes called "the Harvard of the West." The closeness of Stanford to San Francisco, a city thirty-two miles to the north, gives the university a decidedly cosmopolitan (世界性的 ) flavor.

2. The students are enrolled mainly from the western United States. But most of the fifty states send students to Stanford, and many foreign students study here, as well. And standards for admission remain high Young men and women are selected to enter the university from the upper fifteen percent of their high school classes.

3. Not only because of the high caliber (素质 ) of its students but also because of the desirable location and climate, Stanford has attracted to its faculty some of the world&39;s most respected scholars. The university staff has included many Nobel prize winners such as Dr. Felix Bloch, Dr. Robert Hofstadter, and Dr. William Shockley in physics; Dr. Author Kornberg and Dr. Joshua Lederberg in medicine; and Dr. Paul J. Flory and Dr. Linus Panling in chemistry. The Russian novelist Aleksandr Solzhenistsyn has been in residence.

So are bicycling and jogging.

5. In addition to financial support from alumni (校友 ) , Stanford receives grants from the government and from private philanthropic (慈善的 ) foundations. In recent years, government grants have made possible advanced studies in the fields of history, psychology, education, and atomic energy.

Man has always wanted to fly. Some of the greatest men in history had thought about the pr

oblem. One of there, for example, was the great Italian artist, Leonardo Da Vinci. In the sixteenth century he made designs for machines that would fly, But they were never built.

Throughout history, other less famous men had wanted to fly, an example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly every far. Instead, he fell to the ground and broke every bone in his body.

The first real steps took place in France, in 1783. Two brothers, the Montgolfiers, made a very large "hot air ballon". They knew that hot air rises. Why not fill a balloon with it？ The ballon was made of cloth and paper. In September of that year. The King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals land ed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip last- ed twenty-five minutes and they traveled about eight kilometers.

Leonardo Da Vinci ______.

A．said that man would in the sky one day

B．built a kind of machine which never flew

C．drew many beautiful pictures of birds.

D．made designs for flying machines.

第10题

The famous Dr. Edward Jenner was busy trying to solve the problem of smallpox. After study

ing case after case, he still found no possible cure. He had reached an impasse in his thinking. At this point, he changed his tactics. Instead of focusing on people who had smallpox, he switched his attention to people who did not have smallpox. It turned out that dairymaids(挤奶女工)apparently never got the disease. From the discovery that harmless cowpox gave protection against deadly smallpox came vaccination(牛痘) and the end of smallpox as a scourge(灾祸) in the Western world.

We often reach an impasse in our thinking. We are looking at a problem and trying to solve it and it seems there is a deadened, and "aporia" (the technical term in logic meaning "no opening"). It is on these occasions that we become tense, we feel pressured, overwhelmed, in a state of stress. We struggle vainly, fighting to solve the problem. Dr. Jenner, however, did something about this situation. He stopped fighting the problem and simply changed his point of view--from patients to dairymaids, picture the process going something tike this: Suppose the brain is a computer. This computer has absorbed into its memory bank all your history, your experiences, your training, your information received, through life, and it is programmed according to all this data. To change your point of view, you must reprogram your computer, thus freeing yourself to take in new ideas and develop new ways of looking at things. Dr. Jenner, in effect, by reprogramming his computer, erased the old way of looking at his smallpox problem and was free to receive new alternatives.

What does "impasse" probably mean？

A．deadened

B．depression

C．solution

D．peak
