Some plan to use the findings to support calls for closing the nuclear reactors at Indian Point(A nuclear power station is U. S. A. ), the plant closest to New York City. But federal officials, some radiation experts and representatives of the nuclear plants and that minute, occasional releases from such plants were much lower than natural radiation levels,
The new statistical study, which is being published in Archives of Environmental Health, was conducted by a group of scientists who for many years have intended to show a link between mortality and illness and low levels of radiation from power plants, bomb tests and other sources.
The study said the infant death rate in communities for two years before the plant shutdowns averaged 8.44 deaths per l, 000 births and, when all the mortality data for two years after the plant shutdowns were combined, the infant mortality rate dropped to 7.01 per l, 000 births. The difference was statistically significant, the authors said, and the drop was greater than the general drop in infant death rates around the country in recent years.
Joseph Mangano, a public health statistician and the national coordinator for the group, said a statistical link does not prove a cause and effect, but points to the need for more work. He said," The list is literally endless. This doesn't mean we've proved anything beyond a shadow of a doubt, but what I will say is we really need to do more follow-up."
The new study was conducted by______.
A.the government
B.radiation experts
C.antinuclear campaigners
D.public health statisticians

Faster Effective Reading
A higher reading rate, with no loss of comprehension, will help you in other subjects as well as in English, and the general principles apply to any language. Naturally, you will not read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook-but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage (百分比) gained will be the same whatever kind of reading you are concerned with.
The reading passages which follow are all of an average level of difficulty for your stage of instruction. They are all about five hundred words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding at, say, four hundred words per minute, you might drop to two hundred or two hundred and fifty.
Perhaps you would like to know what reading speeds are common among native English-speaking university students and how those speeds can be improved. Tests in Minnesota, U. S. A, for example, have shown that students without special training can read English of average difficulty, for example, Tolstoy's War and Peace in translation, at speeds of between 240 and 250 words per minute with about seventy percent comprehension. Students in Minnesota claim that after twelve half-hour lessons, one a week, the reading speed can be increased, with no loss of comprehension, to around five hundred words per minute.
According to the passage, the purpose of effective reading with higher speed is most likely to help you ______.
A.only in your reading of a physics textbook
B.improve your understanding of an economics textbook
C.not only in your language study but also in other subjects
D.choose the suitable materials for you to practice reading
