单元检测（十六） Sandstorms in Asia.阅读理解AA sandstorm refers to a high amount of wind occurring in sandy areas, usually in deserts, where the wind speed is able to lift the top layer of sand from the ground, and push it in every direction. The sand involved in the sandstorm can reach heights of about 3.05m15.24m.It is very dangerous to experience a sandstorm. Sand can get into the nose, eyes, mouth and lungs. If you happen to be caught in a sandstorm, you must protect yourself by wearing masks, scarves and so on.If youre driving when such a storm approaches, its advised that you pull off the road, since its difficult to continue driving. This is also important since vehicles can fail in during sandstorms and you could end up stuck on the road.Most sandstorms occur in spring, and during the daytime. Many of the areas around the Persian Gulf and the Sahara Desert are associated with the most serious storms. Since its a natural phenomenon, it cant be entirely controlled. In areas that are natural desert regions, you cant always prevent a sandstorm. Theres much evidence that the planet Mars has dust storms, and clearly, no human intervention (介入) is responsible for such.

Their books used the Braille system of raised dots to represent words and numbers. Those with limited or no eyesight can “read” by touching those markings. But Kenyan schools for the blind are now beginning to use technology that provides material in an audible (听得见的) form.Seventeenyearold Lucas Mwanzia is visually impaired (受损的). For the past two years, he has been attending computer classes at the Thika School for the Blind. He said, “The technology has opened doors that once were closed. Braille books are costly and you have to spend a lot of money buying one. With computers, the books are available at little or no cost. So we can download the books to read and when we finish reading we just need to close the program.” Zachary Muasya was born blind. He is now one of the schools teachers. He has been teaching the students how to use the technology for about two years now. “The assistive technology equips the learners with many skills that really make them independent in life. They can read books, magazines and newspapers by themselves.”The school started using assistive technology six years ago. It enables blind and visuallyimpaired students to get information from computers and iPads. The assistive technology costs 1,000 to set up. But a nongovernmental organization called InAble has provided it for the schools at no cost. Four out of Kenyas 11 schools for the blind are using the technology. InAble says it will provide the financing for the remaining schools to join the effort. Peter Okeyo, the program manager at InAble, says blind students using the technology may still have difficulty when they move to higher education. Students who have used the technology up through high school might not have it at the university they attend. Those students might have difficulty if they have to go back to Braille.语篇解读：本文是一篇说明文。肯尼亚盲人学生以及视力不佳者可以不用盲文书籍来学习了，因为科技为肯尼亚盲人学生提供了新的工具。4Compared with Braille books, the books online _.Aoffer less help to studentsBare more difficult to getCcost less or no moneyDare harder to understand解析：选C细节理解题。根据第二段中的“Braille books are costly and you have to spend a lot of money buying one.

Scientists have discovered that the teeth of a limpet (帽贝) are made of even tougher material.“Spider silk has been winning this competition for a long time，” Asa Barber, an engineer at the University of Portsmouth, England, who led the study said. “_1_”A limpet has about a hundred teeth, each about 1 millimeter (0.04 inches) long. _2_ To find out just how tough limpet teeth are, Barbers team examined pieces of the limpets teeth to test their tensile strength the resistance of a material to breaking when stretched. The scientists learned that the material that makes up limpet teeth can withstand a pulling force comparable to that of a rope lifting about 1,500 kilograms (3,300 pounds) of sugar._3_ They contain fibers made from a combination of goethite and chitin. _4_ Chitin, on the other hand, is stretchy (有弹性的). Mix the two together, and you get a material thats both hard and tough.In fact, limpet teeth are 10 percent stronger than spider silk. Scientists have had a hard time trying to artificially produce spiders sticky web material in a lab, but Barber believes it will be easier to recreate limpet teeth. _5_ “I think this is going to be a much greater o
