A
The world's animal populations have decreased by more than two-thirds since 1970, according to recent research from the World Wildlife Fund (WWF).
The London group provided information on 32,000 wildlife populations which included more than 5,000 species. The researchers found that population sizes had reduced by 69 percent on average. They said the loss of forests, human exploitation(开发) of the environment, pollution, and climate change were major causes of the loss. Land-use change is still the biggest threat to wildlife. However, the researchers added, "If we cannot limit warming to 1.5℃, climate change is likely to become the primary cause of biodiversity(生物多样性) loss in the coming years."
Wildlife populations in Latin America and the Caribbean Sea area were greatly affected. The research showed a 94 percent drop in those areas in over 50 years. Wildlife populations in river and lake habitats decreased the most. Freshwater populations have reduced by an average of 83 percent since1970. For example, the population of pink river dolphins in the Amazon River area of Brazil fell by 65percent between 1994 and 2016.
These findings are a red flag that warns of a larger system failure on the horizon. Even one species' population reduction can affect other species, eventually impacting the ecosystem's ability to function. Humans depend on a stable climate, predictable weather patterns, and productive farmland and fisheries to develop, but the current trends are severe enough to threaten many life-sustaining systems.
Our future depends on reversing(扭转) the loss of nature just as much as it depends on addressing climate change. And you can't solve one without solving the other. Everyone plays a role in reversing these trends, from individuals to companies to governments. If nothing changes, animal populations will undoubtedly continue to fall, driving wildlife to extinction and threatening the wholeness of the ecosystems on which we all depend.
1. What has been the greatest threat to wildlife populations recently
A. Illegal hunting. B. Global warming.
C. Land-use change. D. Environmental pollution.
2. How does the author explain the reduction of freshwater wildlife in Paragraph 3
A. By listing figures. B. By analyzing the causes.
C. By making a comparison. D. By referring to a concept.
3. What can we learn from Paragraph 4
A. Climate change threatens many wild animals.
B. Farmland is the basis of life-sustaining systems.
C. Extreme weather events have become more frequent.
D. Species variety is important to maintain a stable ecosystem.
4. What is the main purpose of the text
A. To explain the difficulty of restoring ecosystems.
B. To call on people to take action to protect nature.
C. To present the increasing trend of climate change.
D. To show people's efforts in making up for the loss of nature.
B
When I was eight years old, I entered an art contest hosted by the International Fund for Animal Welfare (IFAW) and I won. I was so excited, but I didn't even know what "endangered" meant at that time. That night, I asked my mom and we found out there were over 6,000 endangered species! I felt sad and angry. I told my mom I would like to help save them from extinction. She asked me, "How " And I told her my plan.
She said once I painted ten, she'd create a Facebook page for me. To my mom's surprise, I had 10 paintings done in 5 days. My Facebook page becomes a platform where I publish new works, share my opinions and raise people's environmental awareness.
Facebook reporters came to interview me and wrote my story and then many other websites shared it, making me shoot to fame overnight. My Facebook followers increased rapidly and some offered me money to hold an art exhibition. One of my paintings was sold at the Wolf Conservation Center at auction(拍卖) for $25,000 this summer.
By the age of 13, I have created more than three hundred paintings of endangered species. I use my website to sell them, and I also donate(捐赠) them and auction them to raise money to support the organizations I work with like IFAW, the Wolf Conservation Center in New York and Jane Goodall's Roots & Shoots. I did a lot of research before choosing those organizations because I wanted to make sure the money I donated would be used for protecting wildlife and their natural homes. Those organizations have helped my dreams come true. Up to now I have donated $69,000, and my goal is $100,000.
We all have an important role to play and if we work together, we will change the world. We need to be brave and original; we should stand out and speak up. It isn't always easy or popular but being true to ourselves is the bravest thing we can do.
1. What plan did the author most probably tell her mother
A. To find out the number of endangered species.
B. To raise people's awareness of animal protection.
C. To establish a Facebook page for endangered species.
D. To sell her paintings to help save endangered species.
2. Which of the following has the closest meaning to the underlined part "shoot to fame" in Paragraph 3
A. Highly stressed. B. Make a fortune.
C. Widely known. D. Go wild with delight.
3. Which of the following best describes the author
A. Talented and caring. B. Patient and brave.
C. Independent and creative. D. Friendly and concerned.
4. What can we learn from the author's experience
A. We should learn to be more creative.
B. We should express our opinions bravely.
C. We should raise money to support organizations.
D. We should try our best to make the world a better place.

答案以及解析
1.答案：working
解析：句意: 我昨天看到他在花园里工作。work与其逻辑主语him是主动关系，表示动作正在进行，需用现在分词作宾语补足语，故填working。
2.答案：running
解析：句意: 请节约用水，不要让水一直流。run与其逻辑主语water间是主动关系，表示动作正在进行，需用现在分词作宾语补足语，故填running。
3.答案：targeted
解析：考查过去分词。句意:图书馆将经常举办针对不同年龄群体的读书会。分析句子结构可知，句中已有谓语will hold，设空处应用非谓语动词。由句意可知，设空处为非谓语动词作后置定语。be targeted at为固定搭配，意为“以……为目标，针对……”，设空处作定语，因此要用过去分词形式targeted。
4.答案：restricted
解析：句意: 所有车辆被限制在市内通行，人们不得不取消出行计划。restrict与其逻辑主语vehicles间是被动关系，故填restricted。
5.答案：surrounded
解析： 考查过去分词。句意：当白雪公主醒过来的时候，她发现自己被七个小矮人围着。本空在句中作宾语补足语，且宾语herself与动词surround之间为被动关系，故本空应用过去分词作宾语补足语。

2.答案：A
解析：推理判断题。根据第三段中的"Freshwater populations have reduced by an average of 83 percent since 1970. For example... fell by 65 percent between1994 and 2016. (自1970年以来，淡水种群平均减少了83%。例如，从1994年到2016年，巴西亚马孙河地区的粉红河豚数量下降了65%。)"可推断，作者主要通过列举数字来解释淡水野生动物的减少。故选A。
3.答案：D
解析：细节理解题。根据第四段中的"Even one species' population reduction can affect other species, eventually impacting the ecosystem's ability to function.(甚至一个物种的数量减少也会影响到其他物种，最终影响到生态系统的运作能力。)"可知，物种多样性对维持稳定的生态系统很重要。故选D。
4.答案：B
解析：推理判断题。文章最后一段提到"从个人到公司再到政府，每个人在扭转这些趋势方面都发挥着作用。如果没有任何改变，动物的数量无疑将继续下降，导致野生动物灭绝，并威胁到我们所有人赖以生存的生态系统的整体性"，结合全文对野生动物数量减少的介绍可推断，本文的主要目的是呼吁人们采取行动保护自然。故选B。
B
答案：1-4 DCAD
1.答案：D
解析：推理判断题。根据第一段中的"I told my mom I would like to help save them from extinction.
