The “c” stands for “crawling”(爬行). This new sport needs twolegged humans running on all fours!‎ The funny idea is the brainchild of Shaun McCarthy. The 34yearold is convinced that it will revolutionize fitness as we know it. According to the sports enthusiast, “The only thing that crunning's changed about fitness is that it's changed everything about fitness.”‎ McCarthy has no scientific evidence to prove that crunning is more efficient than traditional twolegged running. However, he believes it is a more effective way to exercise because it puts an emphasis on the shoulders and arms, providing a complete body workout. McCarthy also says crunning seems to tire him out more. He therefore concludes that the ‎ unconventional exercise is a bigger calorie burner than normal running.‎ While experts generally agree that crunning may provide a better workout, many are not sure if it is the right exercise for humans. Fitness coach Kevin Dean says we are not built to be on all fours and our wrists are therefore not as strong as our ankles. He believes crunning, which he calls a fad(时尚), could result in bad wrist and shoulder injuries, not to mention broken noses.‎ But McCarthy is not worried. Since the release of his crunning video a few weeks ago, many Melbourne residents have been seen scampering around on all fours. As it turns out they are not the only ones. In the Chinese city of Zhengzhou, crawling, a much slower version of crunning, has been a favorite activity for many years. According to some enthusiasts, the light exercise that is believed to date back two thousand years to the Han Dynasty, is good for curing back and spine ailments.‎ Ready to give crunning a try? Then McCarthy recommends investing in some good shoes, hardy gloves and most important of all, a face mask!‎ ‎1．What can we learn about crawling according to Kevin Dean?‎ A．Our ankles are stronger than our wrists.‎ B．Crawling is an efficient way to work out.‎ C．The city of Zhengzhou is the origin of crawling.‎ D．Crawling can burn more calories than normal running.‎ ‎2．What does the author think of crunning?‎ A．Dangerous.　　　　　　 B．Interesting.‎ C．Beneficial. D．Unbelievable. ‎ ‎3．Why does McCarthy suggest people wearing a face mask when crunning?‎ A．To amuse other people. ‎ B．To avoid being recognized. ‎ C．To protect the nose from being injured.‎ D．To prevent sweat dropping on the ground.‎ ‎4．What is the text mainly about?‎ A．A new way of crawling.‎ B．A new trend of exercising.‎ C．A scientific discovery. ‎ D．A traditional way to keep fit.‎ 答案与解析 本文讲述的是跑步、游泳、打球都能起到强身健体的作用，但是你听说过通过爬行来健身吗？这是一种更有效的锻炼方式，因为它把重点放在肩部和臂部，提供一个完整的身体锻炼。在本文中作者介绍了一种新的健身方式——爬行。‎ ‎1．A　推理判断题。根据Kevin Dean的理论可知，他认为我们的脚踝比我们的手腕更强壮。故选A。‎ ‎2．B　推理判断题。根据第二段首句The funny idea is the brainchild of Shaun McCarthy.可以推断出作者认为这种健身方式很有趣。故选B。‎ ‎3．C　推理判断题。根据第四段末句He believes crunning, which ‎ he calls a fad (时尚)，could result in bad wrist and shoulder injuries, not to mention broken noses.可知爬行容易伤到鼻子。故选C。‎ ‎4．B　主旨大意题。跑步、游泳、打球都能起到强身健体的作用。但在本文中作者介绍了一种新的健身方式——爬行。故选B。‎ Ⅱ.七选五 ‎(2017·海南省琼海市嘉积中学质检)‎ How to Protect Yourself from Hackers Online An increase in cyberattacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyberattacks：‎ ‎__1__‎ Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.‎ Change your password regularly A very common mistake made by users is to create one hard password, but then never change it. Remembering a long list of complicated passwords can be difficult. But no password is unbreakable. Hackers are better able to hack multiple accounts if those accounts all have the same password. A password management service, like Dashlane or PasswordBox, can help you ‎ keep track of hard passwords.__2__‎ Clear your browser (浏览器) history This goes for all the devices you use in a day—your home computer, your work computer, or your friend's iPad. Internet browsers like Firefox or Chrome keep track of where you've been and what you've done online. They keep records of every site you visited. __3__ It is very easy for anyone who sees that information to steal a detailed record of your online activities.‎ Do not use free WiFi ‎__4__ Often, a user does not need a password to connect to these wireless networks. These services might be useful, but they're also an easy way for hackers to access everything on your device.‎ Use antivirus protection There are many antivirus services available for users. __5__ Some antivirus services are even free. They are a great way to have a professional help keeping users one step ahead of hackers.‎ A．Be careful while using thumb drive B．These services permit users to easily store and secure their passwords.‎ C．Make your password harder to hack D．They can offer many different types of computer protection.‎ E．An increasing number of public places now offer free wireless access to the Internet.‎ F．Information about what you sent from or saved on your computer can be kept for days or weeks.‎ G．Unless you really need it, it is best not to use it.‎ 答案与解析 介绍性说明文。如何保护电脑免受黑客攻击？本文作者提出几个有效的建议：设置高难度密码；常常更换密码；清除浏览器记录；勿使用免费wifi；使用杀毒软件。‎ ‎1．C　主旨大意题。根据下文阐述的内容：高难度密码最少有八个字符长度。包括大小写字母，数字和生僻汉字等。这样做的目的是使密码难以被黑客破译。故C项切题。‎ ‎2．B　上下文衔接题。根据中心句“Change your password regularly”以及上文“A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords.”可知，密码要经常换。密码管理服务软件，像Dashlane 和 PasswordBox会帮助用户很容易储存和保护密码，使得黑客难以攻破。故B项切题。‎ ‎3．F　上下文衔接题。因为在电脑中你发送和储存的信息会保持几天或几个星期，所以“It is very easy for anyone who sees that information to steal a detailed record of your online activities.(很容易让人窃取你在线活动的详细记录)”。故F项切题。‎ ‎4．E　上下文衔接题。很多公众场合都提供免费的网络路径。所以“Often, a user does not need a password to connect to these wireless networks.(用户不用密码就可以进入网络)” 。故E项切题。‎ ‎5．D　上下文衔接题。“There are many antivirus services available for users.(电脑用户有很多杀毒设施)”，所以它们给电脑提供多种多样的保护。故D项切题。‎ Ⅲ.语法填空 ‎(2017·哈尔滨师范大学附属中学调研)‎ Online shopping is coming into fashion in most cities, where people are able to make full use of the rapidlydeveloped internet technology. Nowadays, can we find a person __1__hasn't experienced online shopping? Definitely not. ‎ Online shopping __2__ (welcome) by most people due to various reasons. From the perspective of consumers, it can save some time for people who don't have much spare time. Just click the mouse, they can get __3__ they want while staying at home. For the retailers, it can cut some costs for those who don't have enough circulating funds. __4__ (compare) with the traditional trade mode, they don't have to spend money in renting a house. __5__，there are still some disadvantages in online shopping. First, a facetoface deal makes online shopping less reliable and trustworthy. Second, people will lose __6__ fun of bargain.‎ ‎__7__ is undeniable that shopping on the internet has become an irresistible trend in modern society. It's __8__ great urgency that we need to make the relative laws __9__ the rapid growth of online shopping. Only in this way can we enjoy the pleasure and __10__ (convenient) of online shopping without the concern of being cheated. ‎ 答案与解析 网购现象越来越普遍，文章讲述了其原因、优缺点及如何使之更规范。‎ ‎1．who/that　考查定语从句。句意：现在你能找到没有网购体验的人吗？定语从句中先行词a person指人，从句可用who/that引导且在从句中作主语。故填who/that。‎ ‎2．is welcomed　考查时态语态。句意：因为各种原因网上购物被很多人欢迎。online shopping与welcome之间为被动关系，且主语为单数，故应用被动语态。故填is welcomed。‎ ‎3．whatever/what　考查连接代词。句意：只是点击鼠标，他们能在家里就得到想要的东西。what/whatever引导宾语从句，并在从句中作宾语。故填what/whatever。‎ ‎4．Compared　考查非谓语动词。句意：和传统的交易模式相比，他们不用花钱租房子。compared with“与……相比”，是固定用法。故填Compared。‎ ‎5．However　考查副词。根据上下文可知，句子前后为转折关系，且用逗号隔开，应用副词however。‎ ‎6．the　考查冠词。句意：人们失去讨价还价的乐趣。特指“讨价还价的乐趣”用定冠词。故填the。‎ ‎7．It　考查代词。句意：毋庸置疑，网购已经成为现代社会中不可抗拒的潮流。it作形式主语，代替that引导的主语从句。故填It。‎ ‎8．of　考查介词。句意：我们需要制定相关的法律是非常紧急的。用be of＋抽象名词＝be＋形容词。故填of。‎ ‎9．with　考查介词。句意：随着网上贸易的迅速增长。with复合结构作伴随状语。故填with。‎ ‎10．convenience　考查名词。由空前的pleasure可知此处应填名词形式与之并列。故填convenience。‎ Ⅳ.短文改错 ‎(2017·阆中中学校检测)‎ My father and I enjoy fishing.‎ One Sunday morning we go fishing at a lake.
