[单项选择]By examining fossilized beetles, a research team has produced the most detailed description yet of temperatures in Britain over the past 22,000 years. Fossils of species that still exist were selected and dated. When individuals of several species found in the same place were found to date to the same period, the known temperature tolerances of the existing beetle species were used to determine the maximum summer temperature that could have existed at that place and period.
The procedure of the researchers assumes which one of the following
A. Beetles can tolerate warm weather better than cold weather.
B. Fossils of different species found in the same place belonged to different periods.
C. The process of dating is more accurate for beetles than for other organisms.
D. The highest actual summer temperature at a place and period equaled the average of the highest temperatures that could have been tolerated by each of the beetle species found there and dated to that period.
E. (E) The temperature tolerance of the beetle species did not change significantly during the 22,000-year period.
[单项选择]When a Scottish research team startled the world by revealing 3 months ago that it had cloned an adult sheep, President Clinton moved swiftly. Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment although no one had proposed to do so--and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning. That group--the National Bioethics Advisory Commission (NBAC)--has been working feverishly to put its wisdom on paper, and at a meeting on 17 May, members agreed on a near-final draft of their recommendations.
NBAC will ask that Clinton’’s 90-day ban on federal funds for human cloning be extended indefinitely, and possibly that it be made law. But NBAC members are planning to word the recommendation narrowly to avoid new restrictions on research that invol
A. federal funds have been used in a project to clone humans
B. the White House responded strongly to the news of cloning
C. NBAC was authorized to control the misuse of cloning technique
D. the White House has got the panel’’s recommendations on cloning
[单项选择] A special research team from the local medical center 76 experiments on completely blind babies. The babies to be tested on lived at home with their mothers or families. The research workers would visit the babies and closely 77 the development of their senses and behavior every two weeks.
In most 78 ,the research workers tested the responses of the blind babies to different stimuli common in the family enviroment. Generally speaking, a 79 baby would react with family. His reactions were swift. 80 , most of the blind babies, according to the experiments, responded to stimuli impassively. In fact, they were indifferent to 81 sound. But 82 some special situations, some of them were able to 83 to the sound of their mothers with a smile. Usually, their response was very 84 .
The tests were done about nine months; they 85 when the blind babies were one month old and ended when they were ten months old.
A. any
B. no
C. some
D. either
