1、1主旨大意题A(2018湖北八校二次联考)Whats small, buzzes here and there and visits flowers? If you say bees or hummingbirds, you get it. You wont be the first if you mix the two up. Now a group of researchers even say we should embrace our history of considering the two together in the same group. The way scientist
2、s study bees could help them study hummingbird behavior, too.Scientists first compared the two back in the 1970s when studying how animals searched for food. The idea is that animals use a kind of math to make choices in order to minimize the work it takes to earn maximum rewards. Researchers at the
3、 time focused on movement rules, like the order in which they visited flowers, and where flowers were located to others.“It was almost like an algorithm(算法) for efficient searching， ” said David Pritchard, a biologist at the University of St. Andrews in Scotland. Hummingbirds and bees had similar so
4、lutions.As the field of animal cognition(认知) appeared, hummingbird and bee research parted. Neuroscientists and behavioral ecologists developed ways to study bee behavior in naturalistic settings. Hummingbird researchers compared hummingbirds to other birds and borrowed methods from psychology to st
5、udy their ability to learn in the lab. To be fair, hummingbirds and bees differ. For example, hummingbirds have more advanced eyes and brains than bees. Honeybees and bumblebees are social; hummingbirds typically arent.“But however they perceive(察觉到) or process information, they both experience simi
6、lar information， ” Dr.Pritchard said. In daytoday searching for food, for example, hummingbirds may rely on more of a beeseye view than a birdseye view. Like other birds, they rely on landmarks, distances and directions to make maps when travelling long distances, but they dont use these cues to fin

10、s Bees答案：【语篇解读】本文是一篇说明文。人们普遍把蜂鸟和蜜蜂混在一起考虑，一组研究人员欣然接受了这种做法并对蜂鸟和蜜蜂进行了研究。1B 解析：细节理解题。本题题干意为：在 20世纪 70年代对蜂鸟和蜜蜂的研究中心是什么？根据题干中的“in the 1970s”可定位到第二段。根据其中的“Researchers at the time focused on movement rules, like the order in which they visited flowers.”(那时的研究人员关注它们的运动规律，如：它们采花粉的顺序)可知答案为 B项。2D 解析：细节理解题。本题题干意
11、为：在研究蜂鸟的学习能力时(研究人员)使用了哪个学科的研究方法？根据文章第三段中“Hummingbird researchers compared hummingbirds to other birds and borrowed methods from psychology to study their ability to learn in the lab.”(蜂鸟研究人员在实验室把蜂鸟与其他鸟类进行对比并引用了心理学的方法研究了它们的学习能力。)可知答案为 D项。3B 解析：细节理解题。本题题干意为：研究人员是如何发现蜂鸟和鸟类不同的？根据最后一段中的“Like other birds，
12、they rely on landmarks, distances and directions to make maps when travelling long distances, but they dont use these cues to find flowers. Move a flower just an inch or so away from where a hummingbird thought it was and it will hover over the flowers original location.”(在长途飞行时，蜂鸟像其他鸟类那样，靠地标、距离和方向来
13、绘制地图，但它们不用这些线索寻找花朵。把一朵花从蜂鸟认为其所在的位置挪动大约一英寸，蜂鸟还会在花朵原来的位置上方盘旋。)可知答案为 B项。34D 解析：标题归纳题。根据全文大意并结合第一段中“Now a group of researchers even say we should embrace our history of considering the two together in the same group. The way scientists study bees could help them study hummingbird behavior，too.”(现在一组研究人员
14、甚至说我们应该欣然接受把这两种动物放在同一个组里考虑的历史。科学家研究蜜蜂的方法也可帮助他们研究蜂鸟的行为。)可知答案为 D项。B(2018湖南六校 4月联考)“Chinas future highspeed trains might be selfdriving, with a top speed of around 600 kilometers per hour and an adjustable interior(内部) and entertainment systems with the highspeed Internet， ” said a senior engineer on M
