五、閱讀理解
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 (濕度), 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 (基因編輯技術), 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．熄滅了的 B．幸存的
C．滅絕的 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

1．cancel(l)ed　2.discuss　3.realization　4.urban
5．prevention　6.pollution　7.frequent
二、英語知識運用
1．C　解析：本題考查形容詞詞義辨析。句意：“她的頭發松散地披在她肩膀上”。morden 意為“現代的”；urban 意為“城鎮的”；sustainable 意為“可持續的”；loose意為“松散的”。故選C。
2．B　解析：本題考查固定搭配。句意：“計劃已經討論了一年了”。under discussion 在討論中，表進行和被動。故選B。
3．D　解析：考查主語從句。句意：——你對第19屆亞運會有什么新的了解嗎？——據說武術將是第一次在亞運會上出現。本句為一般現在時，句中it為形式主語，指代后面that引導的主語從句。“it is said that…”為固定句型，意為“據說……；據傳言……”。故選D。
4．A　解析：本題考查定語從句和表語從句的引導詞。句意：他沒有來的原因是他病了。分析句子結構可知，整個句子的謂語動詞為was，was之前為定語從句；was之后為表語從句；第一個空為定語從句，定語從句中句子結構完整，因此用關系副詞why引導；第二個空為表語從句，表語從句的結構也完整，因此用連詞that引導，that無意義。故選A。
5．B　解析：本題考查過去進行時。句意：“昨天早上七點她正在干什么？”根據“at seven yesterday morning”知是過去進行時，故選B。
6．C　解析：本題考查it用法及主語從句。句意：每個人都知道玩火是危險的，但是困難的是阻止孩子玩火。通過分析句子結構，可知逗號之前的句子包含一個賓語從句。賓語從句中，真正的主語是to play with fire，所以需要用it作形式主語；逗號之后包含一個主語從句，且引導詞在從句中作主語，表示“什么”的含義，故選C。
7．A　解析：本題考查名詞性從句。句意：“約翰向粉絲們展示的是幸福與自信”。根據．..showed her fans was 說明前面整句是主語從句，而主語從句缺賓語，所以用連接代詞what。故選A。

12．A　解析： 本題考查主語從句。句意：“我認為他說的不對。”從句缺成份，what做said的賓語。故選A。
13．C　解析：本題考查表語從句。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.當……的時候；C.怎樣；D.哪一個。根據句意，翻譯成“如何”。故選C。
14．B　解析：本題考查固定短語。句意：“她每天晚上花費兩個小時做作業。” “It takes sb.＋時間 to do sth.做某事花費某人多長時間。”故選B。
15．A　解析：本題考查表語從句。句意：“看起來你喜歡跟孩子們一起工作”。“It seems that...看起來像……”。故選A。

五、閱讀理解
1．A　解析：主旨大意題。根據“From the loss of wildlife to rising sea levels, we’re all well aware of the problems that climate change can cause”可知，第一段是為了引出本文的主題，故選A。
2．C　解析：詞義猜測題。根據“the plant from which chocolate is produced may mean that it will soon become extinct”可知，生產巧克力的這種植物很快就會滅絕，所以extinct表示“滅絕的”，故選C。
3．D　解析：細節理解題。根據“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，大部分的可可生長在靠近赤道的國家，其中超過一半的可可生長在非洲國家加納和象牙海岸，故選D。
4．C　解析：細節理解題。根據“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，關鍵的是土壤和植物中水分的流失，也就是濕度的降低，故選C。
5．D　解析：細節理解題。根據“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，改變可可豆的DNA來解決這個問題，故選D。
