Chocolate could soon be a thing of the past after scientists' warning that the cacao plant, from which
chocolate is made, could be extinct within 32 years.
Over half of the world's chocolate comes from just two countries in West Africa—Cote d'Ivoire and
Ghana—where the temperature, rain, and humidity provide the perfect conditions for cacao to grow. But
rising temperatures over the next three decades caused by climate change are expected to result in a loss of
water from the ground, which scientists say could upset this balance.
According to the related data, a temperature rise of just 2.1℃ could spell an end for the chocolate
industry worldwide by 2050. Farmers in the region are already considering moving cacao production areas
thousands of feet uphill into mountainous areas—many of which are currently preserved for wildlife. But a
move of this scale could destroy the ecosystems that are already under threat from illegal farming and
deforestation.
One of the problems, according to Doug Hawkins, is that cacao farming methods have not changed for
hundreds of years. “Unlike other tree crops that have benefited from the development of modern, high
yielding strains and crop management techniques to realize their genetic potential, more than 90% of the
global cacao crop is produced by small farms with unimproved planting materials，” he said. “It means
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂that we could be facing a chocolate decrease of 100,000 tons a year in the next few years.”
Now scientists at the University of California, Berkeley have teamed up with American candy
company Mars to keep chocolate on the menu. Using the controversial (有争议的) geneediting technology
known as CRISPR they are trying to develop a type of cacao plant capable of surviving in dryer, warmer
climates. If the team's work on the cacao plant is successful, it could remove the need for farmers in West
Africa to relocate to higher ground, and perhaps even allow cacao to be grown elsewhere in the world.
32．What do we know about chocolate from the text?
A．Chocolate will disappear from the menu 30 years later.
B．Chocolate is mainly produced by African countries.
C．Chocolate will not be produced by 2050 because of climate change.
D．A new type of chocolate will be produced with the help of CRISPR.
33．What is the reason for the probable extinction of the cacao plant?
A．The damaged ecosystems.
B．Water shortage caused by climate change.
C．The threat from illegal farming and deforestation.
D．The changeable farming method.
34．What is the writer's attitude to the application of CRISPR to develop a new type of cacao plant?
A．Objective. B．Unconcerned. C．Supportive. D．Negative.
35．Where does the passage probably come from?
A．A poster. B．A leaflet. C．An advertisement. D．A magazine.
【语篇解读】 本文是一篇说明文。文章讲述了可可树因为气候变化而面临灭绝的危险，现在
科学家们正在努力研究新的可可树品种来适应变化的气候。
32．答案与解析：B 细节理解题。根据第二段中的Over half of the world's chocolate comes
from just two countries in West Africa—Côte d'Ivoire and Ghana—where the temperature, rain, and
humidity provide the perfect conditions for cacao to grow.可知，世界上一半以上的巧克力来自西非的
科特迪瓦和加纳这两个国家，因此巧克力主要由非洲国家生产。故选B项。
33．答案与解析：B 推理判断题。根据第二段中的But rising temperatures over the next three
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂decades caused by climate change are expected to result in a loss of water from the ground, which
scientists say could upset this balance.可知，未来30年，预计气候变化造成的气温上升将导致地面失
水，这可能会破坏可可树生长环境的平衡。再结合第三段中的 According to the related data，a
temperature rise of just 2.1℃ could spell an end for the chocolate industry worldwide by 2050.可知，可
可树很可能灭绝的原因是气候变化引起的缺水。故选B项。
34．答案与解析：C 推理判断题。根据文章最后一句If the team's work on the cacao plant is
successful, it could remove the need for farmers in West Africa to relocate to higher ground, and perhaps
even allow cacao to be grown elsewhere in the world.可知，如果该项目取得成功，西非农民就不用搬
迁到高地了，甚至可能允许可可树在世界其他地方种植。由此看出，作者支持该项目，且对该项目
抱有很大希望。故选C项。
35．答案与解析：D 推理判断题。根据文章的内容和文体形式综合分析，本文与科学研究和
环境有关，由此判断这篇文章很有可能来自一本杂志。故选D项。

III.七选五
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
If you were to see a cold, hungry cat in front of your house, would you feed it or walk away? Most
people would walk away instead of taking time to make sure the cat is okay. __36__ They usually have
so much to deal with in their daily life and ignore their surroundings.
Now here's another question: If you see a group of kids hitting and abusing an animal, will you stop
them? Again people would walk away. __37__
Every day animals are abused in their homes or on the streets. It seems as if politicians do nothing to
stop this issue. Everyone is worried about education and global warming. What about animals?
__38__These are the rights that allow animals a place to stay, a shelter if they have no place to stay, the
right not to be abused and many other rights. Are we taking away animals' rights by not giving them a place
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂to stay? Yes, we are. Since I was born, my mother, my sister and I have taken in over fifty homeless cats,
fed them, cleaned them and sent them to good families.
Some people probably give different views, saying, “__39__” It's true. There are people in the
world that need help but we cannot forget the animals. We are all living on this Earth together. Why not
help each other?
__40__ You can volunteer at your local animal shelter, raise money for animal shelters, and inform
your community about animal abuse. You can easily buy a cheap box of dry cat/dog food to feed the
animals.
A．Animals, like us people, have rights.
B．Many people have little knowledge about animals.
C．I'm only one person and I can't make a difference.
D．The problem is that people generally live busy lives.
E．There are many things you can do to help animals around.
F．Some people do not believe that animal abuse is a big thing.
G．There are people in the world who need more help than animals.
【语篇解读】 本文提倡人们关爱身边的动物，因为我们生活在地球上，应互相帮助。
36．答案与解析：D 空后一句讲在日常生活中人们通常有许多事情要处理，从而忽视了周围
的事物，这与D项中的busy lives相呼应。故选D项。
37．答案与解析：F 上文说当人们看到一群孩子打并虐待一只动物时，他们会再次走开，故
空处应该讲他们走开的原因，故选F。
38．答案与解析：A 根据语境并结合下文中的“These are the rights that allow animals...”可知，
作者认为动物和人一样也是有权利的，故A项符合语境。
39．答案与解析：G 空前一句中的different views与下文中的“There are people in the world
that need help”说明，这些人认为有人比动物更需要帮助。故G项正确。
40．答案与解析：E 结合下文内容可知，空处概括下文内容，指你可以做很多事情来帮助周
围的动物。

A young man went to visit the oldest and wisest man in the village for some advice on how he could
become rich.
“Treasure is yours to be had :at the top of Yonder Mountain,” advised the wise old man as he pointed
to a tall mountain in the distance.“You must travel on foot to the top of the mountain. There you will find
riches beyond your belief. Once you leave the top of the mountain, whatever remains will be lost forever.”
The young man could hardly wait until the morning when he was to meet with the wise old man for
final instructions. When he arrived at the wise old man's home, he saw a long, thick log(原木) lying on the
ground in front of the house.
“You must carry this log on your journey to the top of the mountain, and it is a necessary part of your
journey. You must take it with you to the top of the mountain to claim your treasure,” explained the wise
old man.
The young man was not pleased with this sudden surprise, but be respected the wise old man and as he
lifted the long, heavy log onto his shoulders and struggled down the road towards the mountain, he realized
that the trip would not be as easy as he thought.
After he was walking for a while, a woodsman came up to him and said, “It looks like that log is pretty
heavy. Would you like me to cut some of it to make it lighter?”
The young man was very tired, so he said, “I suppose that a little bit cut off the end wouldn't hurt.”
And the woodsman cut two inches off the end.
A while later the young man met a farmer on his way back from the fields. And the farmer helped him
cut another two inches off the end.
At the bottom of the mountain, the young man met up with a trapper(捕杀动物者) who helped him
cut four more inches off the log.
注意: 1.所续写短文的词数应为150左右;
2.续写部分分为两段，每段的开头语已为你写好。

参考范文：
The young man continued to struggle to climb the mountain. Finally with great difficulty he arrived at the
top where the young man saw the most beautiful treasure he had ever seen. What stood between him and
his treasure was a wide opening in the earth which surrounded the mountain top. There was only one way
to get across the opening. Now it became clear why the wise old man had given him this log to carry on his
journey.
The excited young man lay the log across the gap and discovered that it was too short to cover the distance.
Seeing the treasure that can't be reached, how he regretted allowing the woodsman, the farmer and the
trapper to cut eight inches off the long, heavy log. After many vain tries, he had to leave the top. As he
turned to walk down to the mountain side, he looked back with tearful eyes and his treasure slowly
disappeared. He came to the realization that whoever wants to achieve dreams must experience the
struggles first.
