• 16．Growing up in America，I enjoyed the convenience of eating the most attractive，well-packaged foods of the 20th century，including all the candies we often see near the cash register.During those times I wasn't aware how bad sugar was，and in fact，neither was anyone around me.So I continued to spread jam on my toast and eat ice cream daily.
     Strangely enough，I felt that sweet was some sort of wonderful drug which gave me the energy to function properly，to feel good and to perform at my best，all of which seemed necessary for growth.So why should I avoid it？
     Years later，huge food companies，like General Mills and Post，began pumping more sugar into their products，and then more and more people appeared with bigger bellies（腹部）.It finally came to my awareness that our society was becoming more miserable and unfit.And from what？From sugar!I began to do some research into sugar and what it did exactly to our bodies.To my amazement，I found its damage was just as bad as，if not worse than，what alcohol and cigarettes brought about.You see，when you take in more sugar than you need or burn，your body and brain become over-active.This，in effect，causes your cognitive（認(rèn)知的） abilities to slow down，your mood to get to the extremes，your skin to age faster，your blood to become thicker and your liver and kidneys to be worn out.
     But what surprised me most，out of all of these horrible side effects，was that sugar adds extra pounds to your waistline，even if you do exercise regularly.And what I've always wanted，for the past few years，is to remove that extra fat around my belly so that I could finally see my abs（腹?。?
     I just didn't know，this whole time，what damage I had been doing to myself and my dreams，but I knew I had to do something I had never done before.
  
  （1）What did the author use to do？

  
  A．He took in much sugar.
  B．He learnt to cook foods.
  C．He sold ice cream daily.
  D．He had candies packaged.
  （2）What made the author begin to doubt the benefits of sugar？

  
  A．Sugar was unable to provide necessary energy.
  B．More people eating sugary foods became unfit.
  C．Some companies avoided adding sugar to foods.
  D．Many customers stopped buying sugary products.
  （3）What is the third paragraph mainly about？

  
  A．The author's comments on sugar.
  B．The detailed process of the research.
  C．The harmful effect of sugar on health.
  D．The reasons why there search is done.
  （4）What does the author probably decide to do at last？

  
  A．Eat less food.
  B．Cut down sugar.
  C．Do more exercise.
  D．Add extra pounds.

• 17．Houses have been getting progressively "smarter" for decades，but the next generation of smart homes may offer what two Case Western Reserve University scientists are calling an "Internet of Ears".
     Today's smart home features appliances，entertainment systems，security cameras and lighting，heating and cooling systems that are connected to each other and the Internet.They can be accessed and controlled remotely by computer or smartphone apps.
     But a group of electrical engineering and computer science professors in the Case School of Engineering have been experimenting with a new suite of sensors （傳感器）.This system would read not only the vibrations （震動），sounds and even other movements associated with people and animals in a building，but also any slight changes in the existing electrical field.
     While there still maybe a decade or so away，the home of the future could be a building that adjusts to your activity with only a few small，hidden sensors in the walls and floor without the need for monitoring cameras.
     "We are trying to make a building that is able to 'listen' to the humans inside，" said Ming Chun Huang，an assistant professor in electrical engineering and computer science."We are using principles similar to those of the human ear，where vibrations are picked up and our algorithms （計(jì)算程序） recognise them to determine your specific movements.That's why we call it the 'Internet of Ears'."
     "There is actually a constant 60 Hz electrical field all around us，and because people are somewhat conductive，they short out the field just a little，" Huang said."So，by measuring the disturbance in that field，we are able to determine their presence，or even their breathing，even when there are no vibrations associated with sound."
     Huang said they have used as few as four small sensors in the walls and floor of a room.
     As for privacy concerns，the system would not be able to identify individuals，although it could recognise people's different ways of walking.
  
  （1）What uniqueness does the smart home of the next generation have？

  
  A．It uses the advanced Internet technology.
  B．It is controlled remotely by a computer.
  C．It features appliances and entertainment systems.
  D．It can read vibrations，sounds and movements.
  （2）What's the key part of the system in the smart home？

  
  A．The sensors.
  B．The vibrations.
  C．The electrical field.
  D．The monitoring cameras.
  （3）Which is the function of the smart home of the next generation？

  
  A．Determining people's presence.
  B．Recognising different people.
  C．Protecting individuals' privacy.
  D．Measuring the electrical field.
  （4）What may be the best title for the text？

  
  A．Various Smart Houses.
  B．Benefits of Smart Houses.
  C．How Do Smart Houses Work？
  D．What Are Next Smart Homes Like？
