听力原文: Doctors in Chicago said on Monday they reached their conclusions on the fat question after examining 815 people aged 65 and older who did not have Alzheimer's at the start of a nearly four-year study. Those in the study were asked to recall their dietary habits during a more than two-year period before the study began. At the end of the study the researchers found that 131 people had developed Alzheimer's, the debilitating disease that leads to memory loss and eventual physical incapacity. People who consumed the most saturated fat — the kind of fat that comes from meat, poultry, dairy products and palm or coconut oils — had 2.3 times the risk of developing Alzheimer's compared with those who consumed the lowest amount of saturated fats, the researchers said.
How many old people have been examined for the research?
A.815.
B.855.
C.831.
D.865.

听力原文: Computers are being widely used in medicine. The most common use is for keeping hospital patient records. There may be access to these at several points—hospital patient rooms, offices, laboratories and even operating theatres. Computers are also used in the delicate task of looking after patients in the intensive care unit and in monitoring those undergoing surgery.
One of the latest developments is to use computers to assist diagnosis. A computer is programmed with information about a disease, using the accumulated knowledge of many specialists and textbooks. A doctor examining a patient may then be guided by the information given by the computer in what to look for and which questions to ask the patient. The information he gathers is fed into the computer. It may suggest further questions before finally providing a diagnosis.
This kind of procedure causes some people anxiety. They feel it increases the gap in the personal relationship between the doctor and patient. On the other hand, it makes widely available knowledge and skill which before belonged to only a small number of specialists, or which had to be found with difficulty in published material.

At around 9 p.m. ET, a small, bright, silvery circular cloud of light suddenly appeared. Over the next 25 minutes, the cloud appeared to gradually expand and fade, finally becoming invisible to the unaided eye. Those who saw it, wondered exactly what it might have been.
John Bottle, a well-known amateur astronomer with over four-decades of experience of sky observing first caught sight of the cloud at 9:03 p. m. from his home in Stormville, New York. Initially, he thought the cloud was as bright as zero or first magnitude and upon examining it carefully with binoculars, thought that it "... resembled the petals of a day lily." By 9:30 p. m. , he reported that the cloud had faded completely from his view.
From the North Fork of Long Island, Bill Bogardus and his wife were out observing when they took note of the cloud "... about the size of the moon" in the northwest sky. "It was a roundish, yet not all that round, object drifting towards our location very slowly, slower than most satellites because it took at least twenty minutes to move from where we first saw it to pretty much our zenith."
After studying it for a while through an 8-inch telescope, Bogardus noticed two points of light, "... like a satellite would appear, in line and above a jet of gas that seemed to come from them."
Observing from Ithaca, New York, Joseph Storch used 7×50 binoculars on the cloud and reported a star-like point or nucleus and four butterfly shaped petals radiating outward. Other reports, received as far west as Toronto, tell of people who initially thought that what they were seeing was the moon behind a cloud. Typical was the comment: "For a second I thought it was the moon, then I realized the moon was in the east."
What was it?
Quite a few people who saw this strange, expanding cloud thought that it might have been an atmospheric experiment sent aloft by a sounding rocket. Over the years, those living along the East Coast have been accustomed to occasionally seeing unusual brightly colored clouds caused when exotic chemicals such as barium and trimethylaluminum were released into the Earth's ionosphere by rockets launched from NASA’s Wallops Island, Virginia site.
NASA was indeed responsible for the unusual cloud formation on Tuesday night, but it was not part of a planned experiment.
It was, in reality, a fuel dump of the Centaur stage involved in the NRO-1 satellite launch from Cape Canaveral late Tuesday afternoon. Dumping excess fuel is the usual practice for all Centaur-booster assisted launches. It happens after spacecraft separation; the fuel bleeding off from a Centaur upper rocket stage on its second orbit after launch. Being just after nightfall, the cloud of fuel was still sunlit at that altitude.
And those who were fortuitously outside when the dump occurred, were the ones who saw this very unusual sight!
According to the passage, people in ______ places are reported to have seen the unusual sight.
