五、阅读理解
From the loss of wildlife to rising sea levels, we’re all well aware of the problems that climate change can cause.
But while it may seem like such problems won’t influence most of us directly, it looks like future generations could grow up without something that many of us now take for granted: chocolate.
According to an article published by the US National Oceanic and Atmospheric Administration, changes to the climate in the regions that produce cacao (可可豆) the plant from which chocolate is produced may mean that it will soon become extinct.
Most of the world's cacao grows in countries close to the equator (赤道), with over half of it growing in the African nations of Ghana and Ivory Coast.
It’s expected that by 2050, climate change will make temperatures in these countries rise faster, making it extremely difficult for cacao to grow there.
The problem doesn’t lie in increased heat, however, but in lower humidity (湿度), as it is believed that rainfall will stay at the same level if the temperature rises.
“In other words, as higher temperatures take more water out of soil and plants, it’s unlikely that rainfall will increase enough to make up for the loss，” Michon Scotty, the article’s author wrote.
To help fight this problem, researchers from Berkeley University in the US are working on changing the DNA of cacao plants to allow them to survive in dryer conditions by using gene editing technology (基因编辑技术), according to US News.
1．Paragraph 1 is written to ________.
A．introduce the topic
B．explain a problem
C．state how the writer feel about chocolate
D．show why rainfall has decreased in Africa
2．What does the word “extinct”mean in Paragraph 3
A．熄灭了的 B．幸存的
C．灭绝的 D．存活的
3．Where is cacao usually grown
A．In the southern hemisphere (半球)．
B．In the northern hemisphere.
C．In countries with lots of rainfall.
D．In countries near the equator.
4．What does Michon Scott think is the key to the problem
A．Hot weather.
B．Dry soil.
C．Lower humidity
D．High rainfall.
5．What are researchers doing to help solve the problem
A．Finding new laces to grow cacao.
B．Asking famers for help.
C．Changing how cacao is produced.
D．Changing the genes of cacao plants

答案
一、用合适的单词或短语，或其适当形式补全以下句子
1．cancel(l)ed　2.discuss　3.realization　4.urban

二、英语知识运用
1．C　解析：本题考查形容词词义辨析。句意：“她的头发松散地披在她肩膀上”。morden 意为“现代的”；urban 意为“城镇的”；sustainable 意为“可持续的”；loose意为“松散的”。故选C。
2．B　解析：本题考查固定搭配。句意：“计划已经讨论了一年了”。under discussion 在讨论中，表进行和被动。故选B。
3．D　解析：考查主语从句。句意：——你对第19届亚运会有什么新的了解吗？——据说武术将是第一次在亚运会上出现。本句为一般现在时，句中it为形式主语，指代后面that引导的主语从句。“it is said that…”为固定句型，意为“据说……；据传言……”。故选D。
4．A　解析：本题考查定语从句和表语从句的引导词。句意：他没有来的原因是他病了。分析句子结构可知，整个句子的谓语动词为was，was之前为定语从句；was之后为表语从句；第一个空为定语从句，定语从句中句子结构完整，因此用关系副词why引导；第二个空为表语从句，表语从句的结构也完整，因此用连词that引导，that无意义。故选A。
5．B　解析：本题考查过去进行时。句意：“昨天早上七点她正在干什么？”根据“at seven yesterday morning”知是过去进行时，故选B。
6．C　解析：本题考查it用法及主语从句。句意：每个人都知道玩火是危险的，但是困难的是阻止孩子玩火。通过分析句子结构，可知逗号之前的句子包含一个宾语从句。宾语从句中，真正的主语是to play with fire，所以需要用it作形式主语；逗号之后包含一个主语从句，且引导词在从句中作主语，表示“什么”的含义，故选C。
7．A　解析：本题考查名词性从句。句意：“约翰向粉丝们展示的是幸福与自信”。根据．..showed her fans was 说明前面整句是主语从句，而主语从句缺宾语，所以用连接代词what。故选A。
8．A　解析：本题考查定语从句。句意：“英国是众多国家中其中一个人们在左边开车的国家”。先行词the countries在定语从句中作地点状语。故选A。

12．A　解析： 本题考查主语从句。句意：“我认为他说的不对。”从句缺成份，what做said的宾语。故选A。
13．C　解析：本题考查表语从句。句意“不要在意那些嘲笑你的人，最重要的是你如何看待你自己”。 A．什么；B.当……的时候；C.怎样；D.哪一个。根据句意，翻译成“如何”。故选C。
14．B　解析：本题考查固定短语。句意：“她每天晚上花费两个小时做作业。” “It takes sb.＋时间 to do sth.做某事花费某人多长时间。”故选B。
15．A　解析：本题考查表语从句。句意：“看起来你喜欢跟孩子们一起工作”。“It seems that...看起来像……”。故选A。

5．outgoing　6.who/that/whom　7.how　8.carefully

五、阅读理解
1．A　解析：主旨大意题。根据“From the loss of wildlife to rising sea levels, we’re all well aware of the problems that climate change can cause”可知，第一段是为了引出本文的主题，故选A。
2．C　解析：词义猜测题。根据“the plant from which chocolate is produced may mean that it will soon become extinct”可知，生产巧克力的这种植物很快就会灭绝，所以extinct表示“灭绝的”，故选C。
3．D　解析：细节理解题。根据“Most of the world’s cacao grows in countries close to the equator (赤道), with over half of it growing in the African nations of Ghana and Ivory Coast”可知，大部分的可可生长在靠近赤道的国家，其中超过一半的可可生长在非洲国家加纳和象牙海岸，故选D。
4．C　解析：细节理解题。根据“The problem doesn’t lie in increased heat, however, but in lower humidity”以及“In other words, as higher temperatures take more water out of soil and plants, it’s unlikely that rainfall will increase enough to make up for the loss”可知，关键的是土壤和植物中水分的流失，也就是湿度的降低，故选C。
5．D　解析：细节理解题。根据“To help fight this problem, researchers from Berkeley University in the US are working on changing the DNA of cacao plants to allow them to survive in dryer conditions by using gene editing technology”可知，改变可可豆的DNA来解决这个问题，故选D。
