板塊二 能力提升Ⅰ.閱讀理解

• 28．Up to 40% of all food in the United States is wasted.Producing food that people don't consume swallows up roughly 20% of America's cropland and agricultural water，and produces greenhouse gas emissions（排放物） equal to 37 million passenger vehicles each year.Yet，37 million Americans lack consistent access to adequate and nutritious food.
     NRDC's Food Matters Initiative partners cities to confront food waste.Food Matters is piloting all-round，cutting-edge strategies that are easy to follow and share.The first two strategies--and arguably the most critical ones--are to estimate a local baseline level of food waste and then assess the potential for rescuing surplus food.A baseline is necessary in order to understand the scale and natural of the problem.It is also a prerequisite（先決條件） to assessing any progress made，which will help inform future program development.
     Using a calculator tool NRDC developed based on the Food Matters research models，the Atlanta's Mayor's Office of Resilience had a better understanding of the qualities of wasted food and where it was likely occurring.This allowed the city to focus the attention on the solutions that were more closely related to the situation in Atlanta.
     As in many cities across the U.S.，much of the food wasted in Atlanta occurs in households and consumer-facing businesses such as restaurants.Armed with this information，the Mayor's Office of Resilience，creates a restaurant challenge encouraging restaurants to work on the entire system of reduction，rescue，and recycling.After 90 days and participation from 6 restaurants at Atlanta's Hartsfield Jackson airport，the program rescue 21，000 meals and saved owners over ＄62，000.
     Atlanta's restaurant challenge is one of a handful of examples where cities have engaged（吸引） consumer-facing food businesses to reduce their food waste.New York led the charge with a Mayor's challenge to restaurants.Denver recently completed a series of neighborhood restaurant challenges.Nashville has an ongoing Mayor's Food Saver Challenge including not just restaurants but other food businesses as well.Several other cities and countries throughout the country have similar business engagement success stories.
  
  （1）What are the data mainly about in paragraph 1？

  
  A．the harm of food waste.
  B．the cause of food pollution.
  C．the importance of food safety.
  D．the solution to food waste.
  （2）How does Atlanta benefit from the calculator tool of NRDC？

  
  A．It makes new plans for banning food waste.
  B．It helps the city better work on the solutions.
  C．It tests the work efficiency of the government.
  D．It increases the potential for recycling food waste.
  （3）What is the restaurant challenge mainly about？

  
  A．Inspiring customers to order food based on actual need
  B．Teaching waiters to deal with food waste in the greener way.
  C．Encouraging restaurants to reduce food waste in every process.
  D．Making restaurants compete with each other in waste recycling.
  （4）What can we learn from the last paragraph？

  
  A．Restaurant challenges only work in America
  B．More and more cities are focusing on food waste.
  C．Food businesses are the main sources of food waste.
  D．It is difficult to complete the restaurant challenges.

Ⅱ.七選五練習(xí)

• 29．Quantum Communication （量子通信） - Cutting-edge Technology
  What is quantum communication？The scientific world defines it as a "method of communication using quantum effects on communications cycles." （1）

  This technology has grown originally from encrypted messaging and is virtually unbreakable.
     You might ask：How are messages sent by quantum encryption safer？It is because particles of light cannot be divided.An eavesdropper cannot divide a particle of light into two parts，nor can a message in a particle of light be read by a third party or transmitted elsewhere. （2）

  So quantum physics can protect such secret codes，as they can neither be intercepted nor cracked.
     Now you can appreciate the unlimited power of quantum communication. （3）

  And it has achieved results attracting world attention.Among these achievements is the immortal work of Pan Jianwei，Chinas youngest academician.
     The fruit of Academician Pans scientific research into quantum communication was chosen as one of "Ten Worldwide Science and Technology Advances" in 1997. （4）

  
     On Aug.16，2016，China launched a quantum communication satellite it had developed and built itself，making China one of the quantum-communication-producing countries.There are many applications for quantum communication-military，defense，data encryption，telecommunications，insurance，securities，industry and finance. （5）

  Quantum communication is a powerful promoter of the continuous advance of science and technology worldwide.
  
  A.They all need this kind of advanced technology.
  B.Such message may be detected，but it cannot be understood.
  C.Simply put，it is a method of encrypted communication.
  D.Is it so miraculous？If you don't believe it，let us tell you a story.
  E.China has poured a huge amount of effort into research in this field
  F.His research put China in the leading place in the world in quantum communication.
  G.Many Chinese scientists have devoted themselves wholeheartedly to making great contributions.
