第二部分月考滚动检测卷 第三次月考检测卷 [范围：选择性必修第三册Unit1~Unit3] (时间：100分钟满分：120分) 第一部分 阅读（共两节，满分50分） 第一节（共15小题：每小题2.5分，满分37.5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，并在答题卡上将该 项涂黑。 A All living organisms are uniquely adapted to the environment in which they live.Scientists are studying the design and the biological processes of these organisms to get ideas for products and technologies.This field of study is called biomimetics.Here are two examples. 中 Toucan Bills and Car Safety Toucan usually has enormous bills.Scientists have found that the toucan's beak is designed to be both strong and light.The surface is made of keratin,the same material in human fingernails and hair.But the inside of the bill has a foam- Keratin like structure and is made up of a network of light,thin pieces of bone.It con- tains a lot of air,and some areas are hollow,not solid.This design makes the 州 蚁 bill hard but very light. The design of the toucan bill can be used to make cars and planes safer.Studies show that the beak's structure can absorb high energy impacts very well.Car body panels that mimic toucan bills may offer better protection to motorists involved in crashes. Shark Scales and Swimsuits Shark skin may look smooth,but it's actually rough.Sharks are 苏 covered in scales made from the same material as their teeth.Viewed up 角 close,the scales actually look like tiny teeth.These scales protect the shark and help to keep it clean.They are also flexible and can turn or bend in the water.This movement reduces the waters drag on the shark and helps it to swim quickly. Scientists discovered that the shortfin mako's scales vary in size and flexibility over its body.For in- stance the scales on the sides of the body are tapered-wide at one end and narrow at the other.They can turn up or flatten to adjust to the flow of water around the shark and to reduce drag. 49 Scientists believe that shark scales can inspire designs for machines that experience drag, such as airplanes.Designers are also getting ideas from
