Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs.Alternatives to animal testing，such as using human tissue or computer models，are now strongly recommended.In addition，sharing all research results freely should help to reduce the number of animals for scientific use.At present，scientists often share only the results of successful experiments.If their findings do not fit the hypothesis being tested，the work never sees the light of day.This practice means wasting time，money，and animals’ lives in endlessly repeating the failed experiments.

　　Animal experimentation has taught humanity a great deal and saved countless lives.It needs to continue，even if that means animals sometimes suffer.Europe’s new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.

　　【语篇解读　用动物进行试验被人们的舆论推向了风口浪尖，然而，受诸多因素的影响，终止动物试验的道路依然任重而道远。尽管欧洲有严格的法律限制，但是仍然需要另找突破口。

　　．What is the main idea of this passage?

　　A．The success of animal experiments should be ensured.

　　B．A ban on the use of animals in the lab should be enforced.

　　C．Greater efforts need to be taken to reduce the number of lab animals.
