At least 200 elephants have died in Hwange National Park, Zimbabwe in the past two months due to a serious drought (干旱) in the country. National Parks and Wildlife Management Authority spokesman Tinashe Farawo told The Associated Press. Other animals, including giraffes, zebras, hippos and buffaloes are also dying due to the drought. "The situation cannot improve until it rains," Farawo said.
"Almost every animal is being affected," Farawo said. "Of course, elephants are easily noticed, but some bird species are seriously affected because they can only breed (繁殖) in certain tree heights and those trees are being knocked down by elephants."
"In a desperate attempt to locate food and water, animals have come in the park and nearby communities, threatening human populations as well. Thirty-three people have died because of these animals this year," the park said.
"Six hundred elephants and two lion prides will be moved to less crowded parks. A pack of wild dogs, 50 buffaloes, 40 giraffes and 2,000 impalas will also be relocated," Farawo said.
"The animals have exceeded their ecological carrying capacity (生态承载力)," he added. "If the populations go unchecked, the animals will threaten the very ecosystem they depend on for survival."
Typically, park leaders follow a policy of not intervening (干预) to help the animals, but the hard conditions have persuaded them otherwise. Fearing more deaths before the rainy season, they have started bringing in food to help the animals, which usually rely on natural vegetation.
"We used to say nature should take its course," said wildlife officer Munyaradzi Dzoro. "We are now forced to intervene. We are not sure when and how we will receive the rain. To avoid losing animals, we have to intervene to maintain population sizes."
In addition to a lack of food and water, muddy ponds have turned into death traps for the animals. Many have gotten stuck in the clay (泥土)while attempting to reach Long Pool, the park's largest watering hole, which has shrunk to 5% of its normal size, The Associated Press reports.
The drought has affected an estimated 11 million people, according to the World Food Program, which is planning large-scale food distribution.
1. Why are some bird species being affected
A. They can't find enough food and water.
B. They lose many proper breeding places.
C. They are often killed by big land animals.

2. What measure will be taken to improve the serious situation
A. Building fences between the park and nearby communities.
B. Killing the animals which went into human communities.
C. Providing enough water for the animals in the park.
D. Moving some animals to less crowded places.
3. What did Farawo think is the basis for the survival of animals
A. A healthy ecosystem.
B. A policy of not intervening.
C. Large populations of animals.
D. Limited ecological carrying capacity.
4. Muddy ponds have become deadly to the animals because _____.
A. their clay is very attractive
B. much of their water is gone
C. they have become much deeper
D. there is much food in their water

答案以及解析
一、
1.答案：observation
解析： 考查词性转换。句意：她的语言，正如我听到的，是生动的、直接的，并充满了观察力和智慧。根据后面的and wisdom及空前介词of的提示可知此处用名词，observation观察力；监视。
2.答案：following
解析： 考查现在分词。句意：校长走进了房间，一群学生跟着他。分析句子成分可知，此处为独立主格结构作状语，名词students与动词follow之间为主动关系，所以用现在分词following。
3.答案：millions
解析：考查固定用法。此处millions of意为“大量的”。
4.答案：worrying
解析：考查形容词。句意:在伦敦,一年中有四十天会遭受危险程度的污染,这是非常令人担忧的。分析可知此处应用形容词作表语,表示“令人担忧的”应用形容词worrying。
5.答案：shaped
解析：考查非谓语动词。句意:外形酷似鱼的中国深海载人潜水器“奋斗者”号于2020年11月10日创下了一个10,909米的新纪录。分析句子可知设空处作后置定语,shape与所修饰词Fendouzhe之问为被动关系,故填shaped。
二、
答案：1.in the direction of
2.less than
3.On the edge of
4.go round and round
5.picking;up
6.all at once
三、
答案：1-4 BDAB
解析：1.细节理解题。根据第二段中的“Of course, elephants are easily noticed but some bird species are seriously affected because they can only breed (繁殖)in certain tree heights and those trees are being knocked down by elephants"可知,由于大象正在把适合鸟类筑巢繁殖的大树推倒,所以一些鸟类正受到影响,故选B项。
2.细节理解题。根据第四段内容"'Six hundred elephants and two lion prides will be moved to less crowded parks. A pack of wild dogs, 50 buffaloes,40 giraffes and 2, 000 impalas will also be relocated,' Farawo said"可知,D 选项"Moving some animals to less crowded places"(把一些动物转移到不太拥挤的地方)是正在采取的措施故选D项。
3.推理判断题。根据第五段中的"If the populations go unchecked, the animals will threaten the very ecosystem they depend on for survival"可知,Farawo认为健康的生态系统是动物生存的基础。故选A项。
4.推理判断题。根据倒数第二段中的"Many have gotten stuck in the clay while attempting to reach Long Pool, the park's largest watering hole, which has shrunk to 5% of its normal size, The Associated press reports"可知,由于干旱,池塘里的水几乎消失殆尽,许多动物需要踩着淤泥去喝剩下的水,这会导致它们陷入淤泥而无法脱身,这使得泥泞的池塘对动物来说是致命的。故选B项。
四、
答案：①-⑤DFBGC
解析：①根据设空处后一句The answer: you can volunteer.可知，设空处要提出问题，D项符合语境。
②设空处后一句You can choose what really interests you and who or what is most deserving of your time.中的choose和F项中的you've got to pick相呼应；设空处前一句Volunteering isn't school.与F项中的Instead of呼应。故选F项。
③此空是小标题，应该用短小精练的祈使句，所以在A项和B项中选择。根据下文中的what fits into your schedule可知B项（找到适合你的时间表的活动。）切题。此处关键词为schedule。故选B项。
④根据本段语境可知本段讲志愿活动的好处，G项讲的是志愿活动使我们有机会发现我们最擅长、最喜欢的事情，符合语境。G项中的It指代的是上文中的Volunteering，且G项与设空处后一句的结构相似。故选G项。
⑤根据上文it can change the way you look at yourself可知，C项（你可以为自己所取得的成就感到自豪。）承接上文，符合语境。故选C项。
