A.Climate change makes bats migrate earlier. reproduction helps to spread diseaseD.bats are used to living in rainfall seasonsB.bats delay their reproductionC. However, scientists are not certain that climate change alone is causing the Bracken Cave bat colony to migrate earlier. They have found a direct link between seasonal temperatures and bird migration, but bats are also influenced by factors such as changes in wind speed and direction. And there are other plications. “Bats are mysterious little animals that move mostly at night and are difficult to observe and track, Stepanian says. We have this conceptual picture of what might be happening, but really tying it to the cause is the next step.（1）Scientists at Rothamsted Research found that _________. A.Keefe and her colleagues also found that changing bat migration times can also clash with rainfall patterns. Many insects that bats eat breed in seasonal lakes and puddles. If the bats arrive too early to benefit from summer rainfall and the resulting abundance of insects they may struggle to feed their pups(幼崽) or skip reproduction altogether, O39。Keefe, a biology professor at Indiana State University and coauthor of that study, says early arrival at their summer habitats(棲息地) could expose these bats to cold snaps(寒流), and they could freeze to death. annual rhythms, Rothamsted biologist Phillip Stepanian says. Every year migratory(遷徙的) bats travel from Mexico to Bracken Cave, where they spend the summer consuming insects that would otherwise hungrily eat mon food crops. But the bats have been showing up far earlier than they did two decades ago. 【點評】本題考點涉及細(xì)節(jié)理解和主旨大意兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。根據(jù)第五段中的“The results also showed that the individuals buried at the megaliths were related to Neolithic farmers in northern and western Europe”可知埋葬在巨石陣中的人與北歐和西歐的新石器時代農(nóng)民有關(guān)，故選A。故選B。發(fā)現(xiàn)，每座巨石下埋葬著許多人，他們都生活在公元前3800年至公元前2600年之間根據(jù)他們遺體的放射性碳年代測定，他們的血緣關(guān)系非常密切。It indicates the longhidden mystery concerning DNA analysis.D. The people buried in the Ansarve tomb are remarkably different on a genetic level pared to the individuals dug out from huntergather contexts, showing that the burial tradition in this megalithic tomb, which lasted for over 700 years, was performed by distinct groups with roots in the European Neolithic expansion, Magdalena Fraser, cofirst author from Uppsala University, said in the statement.（1）What39。 The evidence suggests that megaliths, prehistoric large stone structures, sometimes acted as graves for family groups in northwestern Europe thousands of years ago. The latest findings throw new light on the origins and social structure of the groups that built megaliths in this region—a history that has long been hidden in mystery.可知這四項活動的共同點都是以科學(xué)為主題的，故選B。故選C。 （1）考查細(xì)節(jié)理解。Science in the Field Whether you want to explore more about food, or just fancy a talk over a meal, join us to mark the first science festival in London.

I really believe that humanity goes for things that make sense. he told Newsweek. If you look at million people dying every year on the roads, if you look at the impact it has on economies based on traffic jams and time lost, it39。 According to Rimac, most people will no longer own or operate their own cars in the future. Instead, vehicles will be shared, self—driving and electric. These changes are already starting. There will be people who still want to own their cars and drive their cars and I am happy for that because that is our business, Rimac said. Long term, I think 20 years down the road, it will be totally changed and people will not own or drive their cars anymore.
