Technology companies and experts from around the world come to the event to see, hear and talk about the latest ideas and inventions. Each year's show has special trends. ‎ Ultra HDTVs (超高清电视)‎ 6‎ One trend at this year's show is the Ultra HDTV. Its picture is much better than that of the regular HDTV. The electronics maker Samsung says it will make more developed Ultra HDTVs. And Sony says all of its televisions will use the Android system. ‎ Internetconnected devices Another trend at the show is the practice of connecting home devices to the Internet. People can now connect dishwashers, stoves and refrigerators to the Internet. However, developers still want to invent a way for all of the devices to be able to communicate with each other. ‎ Wearable devices One such device is a special helmet (头盔) that uses light to grow hair on a person's head. Another device helps reduce pain that people may have had for a long time. Developers also showed a ring that can be used to control other devices using hand movements. ‎ ‎3D devices There has been a large growth in the number of 3D printers produced in the past year. Because of this increase, prices are much lower—several models cost less than $1,000. In addition to 3D printers, there is now a new 3D pen. It lets users draw 3D objects. ‎ Newlydeveloped robots Robots are also shown at this year's show. Some of them help children learn computer programming. ‎ ‎【解题导语】　本文是一篇应用文。文章介绍了今年在拉斯维加斯举行的消费者电子产品展中参展的一些发明和创意。‎ ‎1．What is the purpose of the Consumer Electronics Show?‎ A．To sell latest electronic products. ‎ B．To share new ideas and inventions. ‎ C．To collect money for new technologies. ‎ D．To encourage new ideas and inventions. ‎ 解析：选B　细节理解题。根据文章第一段第二句“Technology companies and experts from around the world come to the event to see, hear and talk about the latest ideas and inventions. ”可知，举办电子产品展的目的是促进新创意和新发明的推广和交流，故答案选B。‎ ‎2．The prices of 3D printers are falling mostly because ________. ‎ 6‎ A．many 3D printers have been produced B．a new kind of 3D printer has been invented C．most people now prefer 3D pens to 3D printers D．people cannot draw 3D objects with 3D printers 解析：选A　细节理解题。根据文章倒数第二段的前两句可知，3D打印机大幅度降价是因为去年的产量大，导致供过于求，故答案选A。‎ ‎3．Which of the following has not yet been invented according to the passage?‎ A．Ultra HDTVs. ‎ B．Internetconnected stoves. ‎ C．Rings that can reduce pain. ‎ D．Robots that help kids learn. ‎ 解析：选C　推理判断题。根据文章五个小标题下的内容可知，目前还没有发明出缓解疼痛的戒指，故答案选C。‎ B When a bee stings (蜇) you, it doesn't just ruin your fun. The insect puts venom (毒液) into your skin, causing pain and swelling. But a chemist in Denmark believes he's come up with a simple device that will draw the venom back out of the wound, bringing victims relief. ‎ Martin Wenckens got the inspiration for the BeePatch (蜜蜂膏药) from a home treatment he saw shown on a Danish television program. After getting stung, a person would put a slight wet sugar cube over the wound. The idea is that through osmosis—the movement of a fluid from an area with a lower concentration of molecules (分子) to an area with a higher concentration—fluid moves from the small hole up into the sugar cube, carrying the venom along with it. ‎ Because exposed sugar may attract more insects, Wenckens thought he could improve on the treatment. He put sugar inside a patch that can be worn like a bandage. The side touching the skin has a thin layer through which fluid can move. “After you get stung, place the patch on the injured skin and leave it for one hour，” Wenckens says. “This will lower both pain and swelling. ” He cautions that people with insect allergies should continue to use medications recommended by their doctors. ‎ Wenckens designed the BeePatch especially for children, but he reports that lifeguards and soccer players are also using it. “In many schools in Denmark, the BeePatch is already a part of first aid kits，” he says. “To have invented a small 6‎ ‎ patch that can be used by so many people of course makes me very proud. ”‎ ‎【解题导语】　本文是一篇说明文。文章主要向我们介绍了一项治疗蜜蜂蛰伤的小发明。‎ ‎4. Wenckens was inspired by ________. ‎ A．his childhood B．a TV program C．a sugar producer D．his private doctor 解析：选B　细节理解题。由第二段第一句中的“got the inspiration for the BeePatch (蜜蜂膏药) from a home treatment he saw shown on a Danish television program”可知，他是从一个有关家庭护理的电视节目里受到启发的。‎ ‎5．What's the advantage of the BeePatch over the original home treatment?‎ A．It is much safer. B．It is more natural. ‎ C．It is much cheaper. D．It is more effective. ‎ 解析：选A　推理判断题。由第三段第一句“Because exposed sugar may attract more insects, Wenckens thought he could improve on the treatment. ”可推断，改进后的发明将糖包起来，不易招惹更多的昆虫，因而比原来的更安全。‎ ‎6．The BeePatch created by Wenckens ________. ‎ A．is not recommended to lifeguards B．may not be helpful for some victims C．will protect victims from bees for an hour D．has an immediate effect on the injured skin 解析：选B　推理判断题。由第三段最后一句“He cautions that people with insect allergies should continue to use medications recommended by their doctors. ”可推断，对昆虫过敏的人被蜜蜂蜇伤后不应简单地使用这种方法治疗，而应采用医生推荐的方法，可知蜜蜂膏药对他们可能不太有帮助。‎ ‎7．The BeePatch is widely used ________. ‎ A．by adults B．in hospitals C．by students D．on football fields 解析：选C　细节理解题。由最后一段中的“In many schools in Denmark, the BeePatch is already a part of first aid kits”可知，蜜蜂膏药被学生们广泛使用。‎ Ⅳ. 七选五 A child can be molded (塑造) in the way that you want him or her to be. For giving the best education to the child, it is very important to teach him or her in a positive atmosphere. 1 So to let a young child have patience is very important. ‎ To do this, first of all, educators need to establish a sense of trust for children. 2 However, as the child grows, it becomes easier to introduce the ‎ 6‎ practice of patience. It is often seen that a child is able to practice learning patience with a positive attitude. Teaching the lessons of patience to children can be milestones of development of different age levels of children. 3 ‎ If you really want to teach your kid these basic qualities, there are so many creative ways which might help you. 4 If parents start telling them patience in their daytoday life, children do catch it and implement (实施) it in their lives. Babies can sense, see and hear reactions. Small children are already very aware of their surroundings and more sensitive to actions and reactions adults make. ‎ Parents can show them examples of enduring patience and introduce them to famous people. 5 Teach them how to handle the situations with more patience so that they can become a better person later on. ‎ A．How can you teach patience lessons to a child?‎ B．Every parent dreams his child can practice a bit of patience. ‎ C．It also reflects what a child is able to do and cannot yet do. ‎ D．Following heroes' lifestyles could be an interesting method too. ‎ E．It is difficult to teach a child how to have patience when he is young. ‎ F．Children really like doing whatever they want to do without being instructed. ‎ G．The best way to sow the seeds of patience in children is through their parents. ‎ ‎【解题导语】　本文是一篇说明文，主要说明培养孩子耐心的重要性，而父母在其中起着重要的作用。‎ ‎1．解析：选B　根据下文“So to let a young child have patience is very important. ”可知，上文需要讲明孩子需要耐心的原因，B项符合语境。‎ ‎2．解析：选E　根据下文“However, as the child grows, it becomes easier ...”可知，上文提到孩子年龄小教他们有耐心是很困难的，E项符合语境。‎ ‎3．解析：选C　根据上文“Teaching the lessons of patience to children can be milestones of development of different age levels of children. ”可知，此空需要衔接上文，进一步说明教孩子有耐心的好处。教孩子有耐心可以弄清孩子会做什么和不会做什么，C项符合语境。‎ ‎4．解析：选G　根据下文“If parents start telling them patience”可知，此处想要说明父母教孩子有耐心是最好的办法，G项符合语境。‎ ‎5．解析：选D　根据上文“introduce them to famous people”可知，此处说明教孩子有耐心的具体的办法，D项符合语境。‎ 6‎ 6‎
