It was previously believed that dinosaurs were cold-blooded creatures, like reptiles. Howe

ver, a recent discovery has lad researchers to believe they may have been warm- blooded. The fossilized remains of a 66 million-year-old dinosaur's heart were discovered and examined by x-ray. The basis for the analysis that they were warm- blooded is the number of chambers in the heart as well as the existence of a single aorta (主动脉).

Most reptiles have three chambers in their hearts, although some do have four. But these that have four chambers, such as the crocodile, have two arteries (动脉) to mix the oxygen-heavy blood with oxygen-lean blood. Reptiles are cold-blooded, meaning that they are dependent on the environment for body heat. Yet the fossilized heart had four chambers in the heart as well as a single aorta. The single aorta means that the oxygen-rich blood was completely separated from the oxygen-poor blood and sent through the aorta to all parts of the body.

Mammals, on the other hand, me warm-blooded, meaning that they generate their own body heat end are thus mere tolerant of temperature extremes. Birds and mammals, because they are warm blooded, move more swiftly and have greater physical endurance than reptiles.

Scientists believe that the evidence now points to the idea that all dinosaurs were actually warm- blooded. Ironically, the particular dinosaur in which the discovery was made was a Tescelosaurus, which translates to "marvelous lizard." A lizard, of course, is a reptile.

According to the author, what theory was previously held and now is being questioned？

A．That dinosaurs were warm-blooded.

B．That dinosaurs had four-chambered hearts.

C．That dinosaurs were swifter and stronger than reptiles.

D．That dinosaurs were cold-blooded.

The wonders which medical workers have already brought about in the diagnosis and treatmen

t of disease suggest that a time may come when the physician will be able to analyze most illnesses as soon as they start, and cure them before damage results. How soon this "golden age of healing" arrives will depend greatly on how close is the collaboration between research workers in medicine and those who Work in the sciences on which medicine depends. The physician has long relied on the chemist for curative drugs and on the physicist for diagnostic instruments and healing rays. In the one field new materials and in the other new devices are being produced in increasing numbers, helping to make imminent new miracles of medicine.

The X-ray and the microscope (显微镜) have extended the vision of the medical observer until he can see through ten inches of living flesh or into a single tissue cell (细胞组织), yet similar but much more powerful tools still await development. Modem electrical devices enable him to listen to faint murmuring of the life processes, or to measure feeble currents arising from heart and brain and nerve; yet electrical body measurements are but little understood. Now newly discovered atomic rays are being brought to help him destroy malignant invaders of the human system, and there is every reason to believe that even more curative rays await discovery.

It can be inferred from the opening sentence of the first paragraph that medical workers______.

A．have contributed little to the diagnosis and treatment of disease

B．have their expectations too high

C．have made remarkable progress in the diagnosis and treatment of disease

D．have developed their potential to the full

"We wanted to capture participants" blood pressure doing whatever they normally 57_______ in everyday life. Getting one or two readings in a clinic is not really 58_______ of the fluctuations that occur throughout the day，" Holt-Lunstad said.

Overall， happily married people scored four points 59_______ on the blood pressure readings than single adults. The study also found that blood 60_______ among married people- especially those in happy marriages—— 61_______ more during sleep than in single people.

"Research has shown that people whose blood pressure remains high" throughout the night are at 62_______ greater risk of heart disease than people whose blood pressure drops，" Holt-Lunstad said.

The study was published in the March 20 63_______ of the joumal Annals of Behavioral Medicine.

The study also found that unhappily married adults have higher blood pressure than bothhappily married 64_______ single adults.

Holt-Lunstad noted that married couples can encourage healthy habits in one 65_______ ， such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support， she said.

第10题

Like a needle climbing up a bathroom scale, the number keeps rising. In 1991, 15% of Ameri

cans were obese (肥胖的); by 1999, that proportion had grown to 27%. Youngsters, who should have age and activity on their side, are growing larger as well: 19% of Americans under 17 are obese. Waistbands have been popping in other western countries too, as physical activity has dechned and diets have expanded. By and large, people in the rich world seem to have lost the fight against flab (松弛).

Meanwhile, poorer nations have enjoyed some success in their battles against malnutrition and famine. Bat, according to research presented at the annual meeting of the American Association for the Advancement of Science, it is more a case of being out of the frying pan and into the fire. The most striking example actually in the poor world comes from the Pacific islands, home of the world's most obese communities. In 1966, 14% of the men on this island were obese while 100% of men under the age of 30 in 1996 were obese.

This increase in weight has been uneven as well as fast. As a result, undernourished and overnourished people frequently live cheek by jowl (面颊). The mix can even occur within a single household. A study of families in Indonesia found that nearly 10% contained both the hungry and the fat. This is a mysterious phenomenon, but might have something to do with people of different ages being given different amounts of food to eat.

The prospect of heading off these problems is bleak. In many affected countries there are cultural factors to contend with, such as an emphasis on eating large meals together, or on food as a form. of hospitality. Moreover, there is a good measure of disbelief on the part of policymakers that such a problem could exist in their countries. Add to that reluctance on the part of governments to spend resources on promoting diet and exercise while starvation is still a real threat, and the result is a recipe for inaction. Unless something is done soon, it might not be possible to turn the clock back.

The first sentence of the passage most probably implies that ________.

A．many Americans are obsessed with the rising temperature in their bathroom

B．more people are overweighed in the United States

C．people are doing more physical exercises with the help of scales

D．youngsters become taller and healthier thanks to more activities
