PAGE PAGE 1 必修第三册 Unit1 单元测试 一、阅读理解 Scientists recently have discovered a new species of bat that has bright orange for and black wings. They later named it Myotis nimbaensis in the journal American Museum Novitates. Jon Flanders, who works at Bat Conservation International (BCI), was leading a team with eight other researchers in the Nimba Mountains in Guinea where they found the orange bat. Many bats live in the mountains’ old mineshafts (井筒) that are now unsafe to enter, so researchers placed nets at the entrances to trap bats while they flew. One night in January 2018, a brightly colored bat standing out among its dark-furred neighbors was also caught in the net. “The color is just unusual. Its wings are black with orange fur. There aren’t a lot of orange bats in the world. I don’t tend to work with that many brightly colored bats. It’s definitely an unusual one for me,” Flanders says. There are about 1,400 bat species in the world, including a few orange ones in China and South America — far from Myotis nimbaensis’s home in West Africa. For the past several years, more than 20 new bat species have been added to the list. However, those discoveries usually come about when scientists tease (梳理) apart the small genetic and physical differences between nearly the same species. “Experienced researchers went out in the field, caught an animal, and said, ‘This is something we can’t identify.’ That’s much more unusual.” says Nancy Simmons, the American Museum of Natural History’s director of mammals. To make sure that they had found something new, the team recaptured (重新捕获) the first bat they had found and compared it with specimens (标本) of other species. After doing some research, the team concluded that the new species of bat is at least five percent different than the closest related species, reports The Times. Next, the scientists hope to study more about Myotis nimbaensis’s ecology — where it lives, what it eats, and what it needs in a habitat. 1.What did
