高中英语 模块检测 (二) 时间：100分钟　分数：120分 第一部分　阅读理解(共两节，满分40分) 第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。 A The last time mammoths(长毛象) lived on Earth was about 10，000 years ago，while one day very soon，you and I could walk among the mammoths.Earlier this year，researchers working with DNA from dead mammoths had a breakthrough.And now，a special lab has been set up in Yakutsk，Siberia—just below the Arctic Circle—with the aim of cloning the mammoths. Yes，you got it.Our long－lost friends could very well suffer“de－extinction”and begin repopulating certain parts of the Earth again.Thats good news for mammoths，I guess，but not such great news for the female elephants which are forced to act as mammoth－hybrid surrogates(代孕者)．The problem is，when humans introduce or reintroduce a species to a new environment，damage is often the result.From cane toads and feral foxes in Australia to mountain goats in Washington States Olympic National Park，harm to ecosystems generally follows. Now imagine herds of mammoths running in great numbers.If thats whats in store for us down the line，scientists will have to find a predator(食肉动物) to keep the mammoth population in check.So naturally，well have to bring saber－toothed tigers back from extinction to help us cut down on our big mammoth problem. But maybe our saber－toothed predators might experience a big population increase，thanks to a plentiful mammoth and human livestock(or perhaps just human)food source.We could hunt them，but what if they turn out to be much more intelligent than wed imagined? Well simply have to dip back into the gene pool of extinct animals and come up with an even smarter，more frightening predator to go after all of our saber－toothed cats.Well，bloody dragons may end up flying in the sky，looking for lunch. Sounds ridiculous？Yeah，it probably is.But just remember，it all started with bringing those mammoths back to life.
