Experiments on monkeys were viewed much more negatively
than those involving mouse. Indeed, only experiments to develop【M1】______
drugs to treat childhood leukemia were seen as justifying monkeys
suffering. In Britain, experiments involving primates are very tightly
controlled. Researchers must convince government officials that the
knowledge be gained justifies any suffering to the animals, and that【M2】______
adequate data cannot be obtained by using other species.
In practice, this means what monkeys are unlikely to be used in【M3】______
leukemia research, as the disease can be studied in other animals. So【M4】______
attempts to develop AIDS vaccines depend heavily on experiments
of related viruses in monkeys, in which some of the animals are likely【M5】______
to become ill. Our poll indicates that a majority of British people
would oppose these experiments.
In the US, where regulations are less stringent, the goal of
developing an AIDS vaccine is seen as sufficient justification for
injecting chimpanzees potentially lethal strains of HIV. And while【M6】______
most people are probably not aware of such facts, 64 percent of
those we polled judged correctly that regulations governing animal
experiments in Britain are stricter than these in other developed【M7】______
countries. Just 11 percent thought that British rules are less strict,
while 24 percent said they didn’t know.
On one respect, however, our poll reveals a disturbing gap in【M8】______
people’s knowledge which the British government might want to
address. No prescription drug is marked without at first being tested【M9】______
in animals, yet people are either unaware that this is the case, but【M10】______
don’t want to acknowledge the fact. [br] 【M5】
选项
答案
in→with
解析
词汇错误。定语从句中的which指它前面的viruses,因此从句的意思应是“带有这些病毒的话……”,故应用表示“带有”意思的with。
