19、】 Children who drink more milk do not necessarily develop healthier bones, researchers said in a report that stresses exercise and modest consumption of calcium-rich foods such as tofu and broccoli. Appearing in the journal Pediatrics, the report drew its conclusions from previously published studie
20、s and was written by researchers from the Physicians Committee for Responsible Medicine, which advocates a strict vegetarian diet. Some earlier studies that extoled dairy products as a calcium source had been funded at least in part by the dairy industry. The U. S. government has gradually increased
21、 recommendations for daily calcium intake, largely from dairy products, of between 800 and 1,300 milligrams to promote healthy bones and prevent osteoporosis. But the Physicians Committees report said boosting consumption of milk or other dairy products was not necessarily the best way to provide th

Her books have sold more than seventy-five million copies. They have been published in more than twenty languages. Now the National Book Foundatio

But book critics say this grandmother has never forgotten what it feels like to be a child. She writes mostl
29、y about the struggles of growing up. She published her first such book in nineteen sixty-nine. Judy Blume says she writes about real life and real feelings. And she says children recognize themselves and their own problems in her books. These are problems like not having friends, or worrying about p
30、hysical development, or being afraid to grow up. Some of the children in her books are trying to understand why their parents have separated. Others are not sure about their religious beliefs.

31、 subjects that she writes about. Her books have often been removed from libraries or placed in restricted areas as a result of challenges by parents. The American Library Association says five of her books are among the one hundred most frequently challenged books. Not surprisingly, Judy Blume is ac

Or it may be only the second busiest. But everything about it is big. The Federal Aviation Administration s
35、ays more than nine hundred thirty thousand flights traveled through OHare last year. During that time, more than sixty-nine million passengers passed through OHare. Most of these people were waiting for connecting flights. As they waited, they could shop at many airport stores. They could eat at air
36、port cafes. They could exercise at a health club or do office work in a business-support center. They could take their children to a flight museum or visit the airports religious center. The huge OHare Airport of today is very different from its beginning. It started as a military air base and facto
37、ry in the nineteen forties. The center produced planes for World War . Later, the airport was named for Navy pilot Edward OHare. He was killed in an action during the war after being honored with medals for bravery. Big as OHare airport is today, however, it is not big enough. Too many airplanes cro

Officials say sixty-five percent of the flights at OHare were delayed during the first seven months of this year. This was the worst record among the nations major airports. To improv
39、e the situation, the governor of Illinois signed the OHare Modernization Act last year. The Act calls for building another runway. Existing runways would be moved and extended.

Many scientists around the w
41、orld had made important discoveries that led to the development of television. But Philo Farnsworth had recognized as a boy that electrons could capture a picture sent as light and sound waves through the air. Over the years, the technology has changed and improved. But the idea behind the televisio
42、n broadcast is still the same. TV stations send a powerful signal from a transmitting antenna. An antenna connected to a television set receives the signal. The problem with this system is that the receiver antenna has to be in line with the transmitting antenna. Mountains or tall buildings can inte
43、rfere. One solution is cable television. This system began in the nineteen forties in Pennsylvania. Only a few television stations existed then, and they were in large cities. People in small towns could not receive the signals. So a store owner put an antenna on top of a pole and placed it on a nea
44、rby mountain. This antenna received the television signal. Wires led from the antenna to the store. The cable brought clear pictures to the television sets inside. Later, the idea of cable television spread to cities, to provide people with more stations to watch. Today, people can watch hundreds of
45、 stations. And another way to receive them is with a satellite dish antenna. A small round device of the size of a pizza can receive signals from satellites .high above the Earth. The antenna is connected to a special receiver which connects to the television set. Some broadcasts over satellite can be watched free of charge. But the others cost money, just like cable service. 17 【正确答案】 D 【知识模块】 听力 18 【正确答案】 B 【知识模块】 听力 19 【正确答案】 B 【知识模块】 听力 20 【正确答案】 A 【知识模块】 听力
