课时作业29 UNIT 3 ENVIRONMENTAL PROTECTION
Ⅰ.阅读理解
(2025·浙江温州二模)A dropped bag of chips disturbed a cave ecosystem in Carlsbad Caverns National Park, New Mexico.This cave is almost cut off from the outside world, so introducing anything foreign can be harmful.“Things in the damp cave get wet quickly，” says park guide Ashley.The snack attracted tiny organisms, causing unwanted growth.Soon, small animals like crickets and spiders came to eat, spreading the pollution.Rangers found the bag within hours.“But that can be all it takes，” says Ashley.“I’m sure some crickets got a bit of the snack.”
Over 500 million people visit American public lands each year, creating many chances to harm wild places.“When you look at the numbers, it’s incredible，” says Watts, head of the Leave No Trace Center for Outdoor Ethic in Colorado, an organization aimed at minimizing human impact on nature.
Food waste takes a long time to break down, especially in certain areas.“It takes much longer for an apple core to rot in a desert than in a forest，” says Blye, a teacher at the University of Utah.Leaving waste introduces animals to an unnatural diet and changes their behavior with sometimes disastrous results.Bears that taste garbage and become a threat to humans may have to be put down.“Bears can get used to unnatural food in three weeks，” says Watts.“Everyone loses in this case.”
Biological waste is also problematic.Dog waste brings new bacteria into the ecosystem and scares away deer.Meanwhile, human waste and toilet paper introduce dangerous bacteria into water sources.
In national parks, trails (小路) are designed to avoid sensitive areas.Stepping off the trail, even for a quick photo, can scare wildlife away.Impacts from many visitors result in long-term damage to nature and wildlife.But people don’t think of that when they see the perfect photo opportunity.“It’s just such a hard thing to resist，” says Blye.The risk to sensitive ecosystems isn’t obvious.“It’s easy to think, oh, there are wild flowers over there.I shouldn’t step on them，” says Blye, but these tiny ecosystems full of microscopic organisms essential to desert life provide many benefits, including reducing the risk of erosion and helping absorb rainfall, and can take hundreds of years to return to their original state.

解析：句意猜测题。第一段的前半部分讲述了“一袋薯片掉落在洞穴里造成的一系列后果”。根据文中的“Rangers found the bag within hours.”以及画线句子开头的“But”可知，此处意思是：虽然护林员在几小时内找到了这个薯片袋，但是损害已经造成了。故选B。

解析：细节理解题。根据第三段中“Leaving waste introduces animals to an unnatural diet and changes their behavior with sometimes disastrous results.Bears that taste garbage and become a threat to humans may have to be put down.”可知，留下外来垃圾会让动物接触到非自然的饮食，从而改变它们的行为，有时甚至会产生灾难性的后果。A 项中的“shift”与原文中的“changes”是同义词。故选A。

A．The rangers’ work is efficient.

A．A shift in animal behavior.
B．A shortage of food supplies.
C．A decline in bacterial species.
D．An increase in regional conflicts.
答案：A
解析：细节理解题。根据第三段中“Leaving waste introduces animals to an unnatural diet and changes their behavior with sometimes disastrous results.Bears that taste garbage and become a threat to humans may have to be put down.”可知，留下外来垃圾会让动物接触到非自然的饮食，从而改变它们的行为，有时甚至会产生灾难性的后果。A 项中的“shift”与原文中的“changes”是同义词。故选A。

A．To praise their benefits to desert life.
B．To highlight our damage to ecosystems.
C．To stress their significance for photography.

[语篇解读]　本文是一篇记叙文。文章讲述了作者从偶然参与公益劳动到持续参与社区公益项目的历程。
1．答案：C
解析：空前描述了三人(I、Julie、Josh)做修剪树篱的准备工作。第二段首句描述在在线群组发布劳动成果照片。由此推断设空处需要一个过渡句，连接“准备工作”和“发布成果”。C项中all three of us呼应上文中的人物，且C项描述了劳动过程。故选C。
2．答案：A
解析：空前描述了作者他们把修剪后树篱的照片发到在线群组后收到了一位轮椅使用者的感谢。空后提到很多人表示自愿维护小镇的整洁。A项体现了人们被带动起来。故选A。
3．答案：D
解析：空后介绍了小镇面貌的变化。D项(有了许多热心人的帮助，我们的镇子已经焕然一新)总领下文，引出了“整洁度提升、居民称赞”的内容。故选D。
4．答案：B
解析：由空后的so判断设空处与下文构成因果关系。空前提及作者找补助，空后提及Julie代表他们申请。B项(我首次尝试申请时未达到法定年龄)解释了Julie代表他们申请的原因。故选B。
5．答案：G
解析：空前提到最初的工具存放在父母的车库里。空后面提到因为东西太多而不得不搬到Julie的车库。G项(我们的车库很快就堆满了刷子、园艺工具和吹叶机)与“在父母的车库”呼应，并解释把东西搬到Julie的车库的直接原因。故选G。(共30张PPT)
