The next day，I could hardly contain my anxiety and headed to the restaurant．My boss wrote out the food order，speaking to the waiter in Mandarin．My heart was beating wildly，but then I noticed a strange thing．Instead of the customary chopsticks，each of us had knives，forks and spoons．
I was confused at first，but then，it hit me．My boss knew that I would have trouble with chopsticks．He wanted to save me from embarrassment，so he had called ahead and arranged for us to be served with knives, forks and spoons．I couldn't believe how thoughtful he was．
Immediately，I made up my mind to take this opportunity to learn how to use chopsticks．______________________________________

Ⅰ．阅读理解
A
Last year，Americans spent more than $22 billion on chocolate．
But the tasty treat comes at a far greater cost than this．
That's because farmers often cut down trees in the rainforest when they need more land to plant cacao trees．This leads to climate change．In turn，climate change hurts cacao crops．This puts chocolate at risk．But experts are developing solutions to ensure its future．
课时分层作业(十二)
Chocolate comes mainly from the Cocoa Belt，a narrow piece of land along the equator．In the Cocoa Belt，it is hot and rainy．The conditions are perfect for growing cacao．But in recent years，climate change has a bad influence on the weather in the Cocoa Belt．As a result，cacao trees produce fewer beans．Climate change has also led to the spread of disease that harms trees．
In 2013，researchers studied the changing conditions in the Cocoa Belt．They said that by 2050，it will be harder to grow cacao in 90% of places where it is now planted．But Christian Bunn of the International Center for Tropical Agriculture says chocolate won't disappear anytime soon．Plans to protect it are already taking shape．
One solution to the problem is cross-breeding．Scientists have developed new cacao trees that stand up to disease．Some even produce more cacao．
Weather stations will also help．Groups are building them in Africa．Around 70% of cacao is grown there．Information from the stations will help farmers know when to plant trees．“Years back，farmers would follow farming rules that go with the seasons，” Bunn said．“Those rules don't always apply anymore．”
These fixes could help farmers grow more cacao on less land．That could help end the push to clear rainforest．That's good for chocolate，and a sweet deal for the planet．
“Everything has a side effect，” Bunn said．“We have to be smarter about our food．”
【语篇解读】 本文是一篇说明文。文章主要介绍了气候变化导致可可产量下降，这使巧克力处于危险之中。但专家们正在开发解决方案，以确保它的未来。
1．What causes a drop in cacao crops according to the text
A．Climate change． B．Less farmland．
C．Water pollution． D．Higher costs．
A [细节理解题。根据第二段中“In turn，climate change hurts cacao crops．”和第三段中“But in recent years，climate change has a bad influence on the weather in the Cocoa Belt．As a result，cacao trees produce fewer beans．”可知，气候变化导致可可产量下降。故选A。]
√
2．What do the underlined words “stand up to” in paragraph 5 probably mean
A．Go with． B．Protect against．
C．Die from． D．Bring about．
B [词义猜测题。根据第三段中“Climate change has also led to the spread of disease that harms trees．”和画线词句前文“One solution to the problem is cross-breeding．”以及后文“Some even produce more cacao．”说明科学家有办法防止树木的疾病，从而推知画线短语意思是“防止”。故选B。]
√
3．What is the author's attitude to the chocolate protection plans
A．Doubtful． B．Uncaring．
C．Positive． D．Confused．
C [推理判断题。根据倒数第二段“These fixes could help farmers grow more cacao on less land．That could help end the push to clear rainforest．That's good for chocolate，and a sweet deal for the planet．”可知，作者对这些措施持肯定态度。故选C。]
√
4．What can be a suitable title for the text
A．Solutions to Saving Chocolate
B．Steps to Protect Rainforest
C．New Ways to Plant Cacao Trees
D．Side Effects on Traditional Farming
√
A [标题归纳题。根据第二段中“In turn，climate change hurts cacao crops．This puts chocolate at risk．But experts are developing solutions to ensure its future．”以及接下来的描述可知，本文主要介绍气候变化导致可可减产，进而引发巧克力生产处于危险之中，对此，相关专家提出应对的解决方案。所以文章最好的标题应为：拯救巧克力的解决方案。故选A。]
B
If you think of the jobs robots could never do，you would probably put doctors and teachers at the top of the list．But，in some cases，they already perform better than doctors at diagnosing illness．Also some patients might feel more comfortable sharing personal information with a machine than a person．Could there be a place for robots in education after all
British education expert，Anthony Seldon thinks so．And he even has a date for the robot takeover of the classroom: 2027．He believes robots will do the main job of transferring information and teachers will be like assistants．Intelligent robots will read students' faces，movements and maybe even brain signals．Then they will transfer the information to each student．It's not a popular opinion and it's unlikely robots will ever have empathy (共情) and the ability to really connect with humans like another human can．
One thing is certain，though．A robot teacher is better than no teacher at all．In some parts of the world，there aren't enough teachers and 9—16 percent of children under the age of 14 don't go to school．Teachers all over the world are leaving because it is a difficult and lower-paid job and they feel overworked．That problem could be part solved by robots．
Perhaps the question is not “Will robots replace teachers？” but “How can robots help teachers？” Teachers waste a lot of time doing non-teaching work，including more than 11 hours a week marking homework．If robots could cut the time teachers spend marking homework and writing reports，teachers would have more time and energy for the parts of the job humans do best．
【语篇解读】 本文是一篇说明文。文章主要说明了机器人在教育方面的应用以及机器人老师的作用。
5．What's the function of the first paragraph
A．Drawing a conclusion．
B．Giving an answer．
C．Presenting an example．
D．Introducing the topic．
D [推理判断题。根据第一段内容可推知，第一段的作用是为了引入话题。故选D。]
√
6．Why are robot teachers necessary
A．Because robot teachers cost less．
B．Because robot teachers teach better．
C．Because there aren't enough teachers．
D．Because there are already robot doctors．
C [细节理解题。根据第三段中“In some parts of the world，there aren't enough teachers and 9—16 percent of children under the age of 14 don't go to school．”可知，需要机器人老师是因为教师资源不足。故选C。]
√
7．How is a robot expected to help a teacher by the author
A．By answering emails．
B．By marking homework．
C．By reading students' faces．
D．By analyzing brain signals．
B [细节理解题。根据最后一段内容可知，机器人可以帮助老师批改作业。故选B。]
√
8．Which can be the best title for the text
A．Illness Diagnosing
B．Robot Teachers
C．Information Transferring
D．Education Problems
√
B [标题归纳题。根据第一段的“Could there be a place for robots in education after all？”和第二段的“British education expert，Anthony Seldon thinks...and teachers will be like assistants．”可知，文章主要介绍了机器人将扮演教师的角色。因此B选项“机器人教师”最符合文章标题。故选B。]

The exhibition will be held in our science and technology museum．It will start on December 10 and last for seven days．Not only can you witness robots that do housework，but you can also experience self-driving vehicles．More interestingly，you can play the board game with AlphaGo，which is a computer program developed by a famous company．Meanwhile，a wide variety of the latest technologies will be displayed，including facial recognition．
I believe that you will be deeply impressed by the exhibition．Looking forward to your reply．
Yours，

Ⅰ．【语篇解读】 本文是一篇说明文。文章主要介绍了气候变化导致可可产量下降，这使巧克力处于危险之中。但专家们正在开发解决方案，以确保它的未来。
1．A [细节理解题。根据第二段中“In turn，climate change hurts cacao crops．”和第三段中“But in recent years，climate change has a bad influence on the weather in the Cocoa Belt．As a result，cacao trees produce fewer beans．”可知，气候变化导致可可产量下降。故选A。]
2．B [词义猜测题。根据第三段中“Climate change has also led to the spread of disease that harms trees．”和画线词句前文“One solution to the problem is cross-breeding．”以及后文“Some even produce more cacao．”说明科学家有办法防止树木的疾病，从而推知画线短语意思是“防止”。故选B。]
3．C [推理判断题。根据倒数第二段“These fixes could help farmers grow more cacao on less land．That could help end the push to clear rainforest．That's good for chocolate，and a sweet deal for the planet．”可知，作者对这些措施持肯定态度。故选C。]
4．A [标题归纳题。根据第二段中“In turn，climate change hurts cacao crops．This puts chocolate at risk．But experts are developing solutions to ensure its future．”以及接下来的描述可知，本文主要介绍气候变化导致可可减产，进而引发巧克力生产处于危险之中，对此，相关专家提出应对的解决方案。所以文章最好的标题应为：拯救巧克力的解决方案。故选A。]
【语篇解读】 本文是一篇说明文。文章主要说明了机器人在教育方面的应用以及机器人老师的作用。
5．D [推理判断题。根据第一段内容可推知，第一段的作用是为了引入话题。故选D。]
6．C [细节理解题。根据第三段中“In some parts of the world，there aren't enough teachers and 9—16 percent of children under the age of 14 don't go to school．”可知，需要机器人老师是因为教师资源不足。故选C。]
7．B [细节理解题。根据最后一段内容可知，机器人可以帮助老师批改作业。故选B。]
8．B [标题归纳题。根据第一段的“Could there be a place for robots in education after all？”和第二段的“British education expert，Anthony Seldon thinks...and teachers will be like assistants．”可知，文章主要介绍了机器人将扮演教师的角色。因此B选项“机器人教师”最符合文章标题。故选B。]
