Ⅰ.阅读理解
A
In the age of the Internet­of­things，nearly everything in your house is connected to a network.While you may be comfortable enough to use smart devices to manage your everyday tasks，will you be comfortable with them looking after your children as well？That's one question that can possibly arise with Google's latest patent—a “remote babysitter” that makes use of cameras and motion sensors(运动传感器)to track children at home.
According to the search giant's patent application，the proposed device aims to protect children in a home by disabling potential dangerous devices and by providing child­protection warnings.
The “smart babysitter” may use its sensors to determine if a child is left unattended in a room.According to the application，this will be done by scanning the room for persons with a threshold(门槛)．Video and sensors may be used to pick up persons below the threshold like crawling babies and children who are just learning to walk.When there is no person that meets the height of the threshold for a given amount of time，then the program will email the parents of the unattended child.
Moreover，“smart wall plugs” will also discover the occupancy in one room.Data will also be gathered to disable unused electrical outlets(插座)when a child comes into contact with them.They can also disable electronically controlled door handles in the event that a child gets close to them.
Added features that have been shown in the patent include blinking lights and audio warnings like “Your child is approaching an electrical outlet” or “Your child is alone for 10 minutes”．All these will be powered by Internet­connected motion detectors and cameras in order to track the child's movements，as well as smart devices around the home.
[语篇解读]　本文是一篇说明文。文章主要介绍了谷歌发明的一款可以照看孩子的“智能保姆”。
1．What's the main purpose of the “smart babysitter”？
A．To protect children from dangers at home.
B．To look after children with no adults in the room.
C．To allow parents to monitor their children at work.

解析：细节理解题。根据第二段可知，这款“智能保姆”的主要目的是保障孩子在家里的安全。
答案：A
2．In which situation will the “smart babysitter” warn parents?
A．A child falls over in the room.
B．A baby is crawling in the room.
C．There is a person in the room higher than the threshold.
D．The person that can meet the height of the threshold is absent for long.
解析：细节理解题。根据第三段的最后一句可知，当达到门槛高度的人在一定时间里没有出现在房间时，这款“智能保姆”就会给孩子的父母发邮件。
答案：D
3．If a child approaches an electronically controlled door handle，________．
A．the door will open automatically
B．the handle won't function normally
C．cameras will begin to keep track of the child
D．all smart devices around the home will stop working
解析：推理判断题。根据第四段的最后一句可知，当孩子靠近电子门锁时，这种智能插座就会给门锁断电，这样门锁就无法正常工作了。
答案：B

Do you have calluses(茧)on your feet？Don't fear them，though.New research shows that foot calluses—thickened skin that forms naturally when one walks barefoot—have evolved to protect the feet and provide for comfortable walking in perhaps ways that shoes can't match.The researchers stressed that their findings don't show that walking barefoot is healthier than walking in shoes.At its core，the study is about human evolution.
For most of human's 200，000­year existence，we walked barefoot.The oldest discovered footwear dates back to about 8，000 years ago，although there is indirect evidence of sandals(凉鞋)tens of thousands of years before this，the researchers said.Cushioned shoes are even more recent—only about 300 years old.
Because calluses are the evolutionary solution to protecting the foot，Daniel Lieberman，co­leader of the study，and his team set out to assess how they might differ from shoes in maintaining grounding and comfort.Their study examined the foot calluses of more than 100 adults.About half of the subjects walked barefoot most of the time，and half mostly wore shoes.
Among the barefoot walkers，the thickness of the calluses didn't prevent the foot from feeling the sensation(知觉)of the ground while walking.Shoes，with their cushioned bottoms，clearly mute this sensation.However，very thick calluses don't simply act like shoe cushions.The thickness of the calluses can protect the foot against heat or sharp objects，providing comfort and safety，like shoes can，but signals can also be sent to the brain if there are ground surface differences.These signals may help the barefoot walker keep balance，strengthen muscles and create a stronger neural(神经的)connection between the foot and the brain.“We advise children to walk barefoot on the grass with the purpose of stimulating the nerves traveling to the brain for developmental reasons，” said Thomas Milani，co­leader of the study.
Researcher Paul Zehr added that one of the study's limitations is that this sensitivity was assessed at rest，and so these results may not necessarily hold true for walking.What's more，walking barefoot，people with certain diseases may wound their feet and not realize it.
[语篇解读]　本文是一篇说明文。新的研究表明，脚茧可以让我们的行走更加舒适，并能起到保护脚的作用。
5．What does the underlined word “mute” in Paragraph 4 mean?
A．Lower.　　　　　　　 B．Produce.
C．Experience. D．Strengthen.
解析：词义猜测题。根据上下文可知，在赤脚行走的人当中，老茧的厚度并不会降低触觉的敏感性，也不会降低步行时脚部对地面的感知力，而软底鞋明显地减弱了这种感觉。由此可知答案。
答案：A
6．What advantage do calluses have over shoes according to the research?
A．They can help prevent brain injury.
B．They make walking more comfortable for people.
C．They can improve people's physical health more greatly.
D．They offer protection without compromising sensitivity.
解析：细节理解题。根据第四段的第一句和第四句可知，行走时，脚茧并不会妨碍脚部对地面的感知。也就是说，脚茧在保护脚部的同时并不会影响脚部的敏感度。
答案：D
7．What can we learn from the last paragraph?
A．Walking barefoot tends to cause diseases.
B．Barefoot walking isn't suitable for everyone.
C．The researchers were confident of the results.
D．People's feet become less sensitive while having a rest.
解析：细节理解题。根据最后一段的最后一句可知，如果赤脚走路受伤时，患有某些疾病的人可能也不会察觉到。由此可见，赤脚走路并不适合所有人。
答案：B
8．What is the best title for the text?
A．How the Shoes Evolve over the Years
B．Why We Get Calluses When Walking Barefoot
C．Why Your Foot Calluses Might Be Good for You
D．The Differences Between Foot Calluses and Shoes
解析：标题归纳题。文章第一句首先提出问题，然后再用一项新的研究说明脚茧的好处。由此可知答案。
答案：C
Ⅱ.阅读七选五

If making friends and socializing is your goal，you may call up your friends and schedule walks with them，since this will introduce you to new places and trails.You might also find open groups of dog walkers at your local park.Your campground staff might know about fun local walking groups you can join.
__4__ In cities large and small all over the country，walks are going on almost every weekend in support of cancer research，diabetes research，and other humanitarian causes.
__5__ Then tie your walking shoes and prepare to get to know the new area from the ground up！Many of our great historic cities offer detailed and well­planned walking tours.Nearly any city you can think of offers a walking tour with maps，provided by the tourist administration.
