【文章大意】 本文是一篇说明文。文章主要介绍了投资生态创新如何有助于实现更可持续的未来,特别是从科技行业的角度进行了探讨。
1.C　细节理解题。根据第二段“When it comes to the environment, it can be argued that the technology industry is both the problem and the solution. Tech is responsible for between 3.5% and 4% of global greenhouse gas emissions (排放物). And the EU believes the Information and Communication Technology (ICT) sector is responsible for 10% of all electricity consumption. On the other hand, we all want a sustainable future for the planet. Yet we also want the convenience and fun of modern living. Obviously, only eco-innovation can deliver the solutions.”可知,我们可以了解到科技行业有益于环境,也会破坏环境。故选C项。
2.A　细节理解题。根据倒数第二段“Until recently, most agricultural improvements focused on the development of machines. Now digital tools are causing a new wave of efficiency. Innovative farming companies are looking to increase farm efficiency and reduce input waste through farming techniques. And they are using real-time devices located in the field or equipment. The data collected by these devices help farmers make better decisions about where to provide effort and resources while reducing the environmental footprints.”可知,数字设备的使用在农业改良中起重要作用。故选A项。
3.C　推理判断题。根据最后一段“As people’s awareness of environmental protection continues to increase, the tech industry needs to keep working on the inventions like those described above. These breakthroughs will help us all to do more with less. Also, tech companies are facing calls to keep their own houses in order. Lawmakers and consumers want them to use fewer materials in the production process and rethink their approach to recycling and waste. The good news is that governments and eco-innovative companies have already carried out a major clean-up mission.”可知,科技公司需要管好自己内部事务,在生产过程中使用更少的材料,并重新考虑他们回收的方法,避免浪费,所以科技公司应该观察他们的环境行为。故选C项。
4.D　主旨大意题。根据第一段“Every April 22 people come together to take action that will protect the environment. One theme of Earth Day is ‘Invest (投资) in Our Planet’. So how is investment in eco-innovation helping to deliver a more sustainable future ”以及纵观全文可知,本文主要讲述了科技行业对环境有好处也有坏处,指出生态创新对改善环境的重要性,所以D项(生态创新与环境保护)是本文最好的标题。故选D项。

【文章大意】 本文是一篇说明文。文章讲述了研究发现,因为人类活动对珊瑚礁的破坏,礁鲨数量的下降似乎尤为严重,但Simpfendorfer和他的团队也发现了礁鲨的恢复潜力。
5.C　细节理解题。根据第二段“The study by Simpfendorfer with his team is the result of an act of worldwide cooperation called the Global FinPrint Project. The data analysed include more than 20,000 hours of standardized underwater video taken at nearly 400 reefs in 67 countries around the world. It reveals declines of 60% to 73% of once-abundant reef shark species at reefs around the world. The global conservation status of sharks and rays (鳐鱼) is worse than a decade ago and is even more concerning for some groups of sharks.”可知,从本段可以了解到这项研究分析了珊瑚礁中鲨鱼种类的数据。故选C项。
6.D　细节理解题。由第三段中“The reefs with healthier shark populations had some important similarities: they tended to be in the waters of high-income countries with stronger natural resource management laws and rules.”可知,由于高收入国家有严格的环保相关的法律,所以健康的礁鲨种群仍然存在。故选D项。
7.A　推理判断题。由第四段内容和最后一段中“The loss of sharks and the ecosystem services they provide represents an ecological disaster that can cause substantial harm to humans.”可知,鲨鱼及其提供的生态系统服务的丧失是一场生态灾难,会对人类造成重大伤害。由此可推知,人类和动物在生态系统中共存。故选A项。
8.B　主旨大意题。由第一段中“Coral reefs (珊瑚礁) provide homes for countless fish species that are vital for fisheries and are therefore an especially important ecosystem for humans—and one where the decline of shark populations seems to be especially sharp.”,第三段中“However, the findings of Simpfendorfer with his team include signs of hope and a clear path forward. Their results show that although shark populations in many reefs had declined, some healthy reef shark populations remained.”,第四段中“They found that one reef could be overfished so badly that a once-common reef shark species was totally gone, but another reef a short distance away could have healthy populations of that same species.”和全文内容可知,文章讲述了研究发现,因为人类活动对珊瑚礁的破坏,礁鲨数量的下降似乎尤为严重,但Simpfendorfer和他的团队也发现了礁鲨的恢复潜力。由此可知,B项“礁鲨的潜在恢复”能概括文章大意。故选B项。

Every April 22 people come together to take action that will protect the environment. One theme of Earth Day is “Invest (投资) in Our Planet”. So how is investment in eco-innovation helping to deliver a more sustainable future
When it comes to the environment, it can be argued that the technology industry is both the problem and the solution. Tech is responsible for between 3.5% and 4% of global greenhouse gas emissions (排放物). And the EU believes the Information and Communication Technology (ICT) sector is responsible for 10% of all electricity consumption. On the other hand, we all want a sustainable future for the planet. Yet we also want the convenience and fun of modern living. Obviously, only eco-innovation can deliver the solutions.
Eco-innovation is the key to doing more with less. All over the world, and across many different industries, innovators are working to reduce the human footprints while improving productivity. Innovative farming is a good example.
Until recently, most agricultural improvements focused on the development of machines. Now digital tools are causing a new wave of efficiency. Innovative farming companies are looking to increase farm efficiency and reduce input waste through farming techniques. And they are using real-time devices located in the field or equipment. The data collected by these devices help farmers make better decisions about where to provide effort and resources while reducing the environmental footprints.　
As people’s awareness of environmental protection continues to increase, the tech industry needs to keep working on the inventions like those described above. These breakthroughs will help us all to do more with less. Also, tech companies are facing calls to keep their own houses in order. Lawmakers and consumers want them to use fewer materials in the production process and rethink their approach to recycling and waste. The good news is that governments and eco-innovative companies have already carried out a major clean-up mission.
(　)1.What can we learn about the technology industry according to Paragraph 2
A.It contributes to saving electricity.
B.It will change our traditional way of life.
C.It benefits and damages the environment.
D.It is a major cause of greenhouse gas emissions.
(　)2.Which of the following plays an important role in agricultural improvement
A.The use of digital equipment.
B.The training of farmers.
C.The collection of resources.
D.The invention of machines.
(　)3.What are tech companies expected to do
A.Build more greenhouses.
B.Meet the market requirements.
C.Watch their environmental behaviour.
D.Change their management style.
(　)4.What is the best title for the text
A.The long-term goal of Earth Day
B.Modern farming and technological change
C.The key to the development of technology industry　
D.Eco-innovation and environmental protection

Sharks and their relatives are some of the most threatened vertebrates (脊椎动物) on Earth. Coral reefs (珊瑚礁) provide homes for countless fish species that are vital for fisheries and are therefore an especially important ecosystem for humans—and one where the decline of shark populations seems to be especially sharp.
The study by Simpfendorfer with his team is the result of an act of worldwide cooperation called the Global FinPrint Project. The data analysed include more than 20,000 hours of standardized underwater video taken at nearly 400 reefs in 67 countries around the world. It reveals declines of 60% to 73% of once-abundant reef shark species at reefs around the world. The global conservation status of sharks and rays (鳐鱼) is worse than a decade ago and is even more concerning for some groups of sharks.
However, the findings of Simpfendorfer with his team include signs of hope and a clear path forward. Their results show that although shark populations in many reefs had declined, some healthy reef shark populations remained. The reefs with healthier shark populations had some important similarities: they tended to be in the waters of high-income countries with stronger natural resource management laws and rules. Unfortunately, such countries were relatively rare, and lower-income countries tended to have fewer resources for eco-friendly management.
The most unexpected result of the study is that a decline or complete loss of shark species in one reef was not always associated with similar changes in nearby reefs. They found that one reef could be overfished so badly that a once-common reef shark species was totally gone, but another reef a short distance away could have healthy populations of that same species.
The problem is clear—animals that provide ecosystem services that are vital for human food security and livelihoods are disappearing at an alarming rate. The loss of sharks and the ecosystem services they provide represents an ecological disaster that can cause substantial harm to humans.
(　)5.What can we learn about the study from the second paragraph
A.It was directed by the Global FinPrint Project.
B.It was to find out the reasons for ocean pollution.
C.It analysed data about shark species in coral reefs.
D.Certain sharks were found endangered in the study.
(　)6.Why could healthy reef shark populations remain in some areas
A.Citizens there had a strong environmental awareness.
B.Science and economics were improving fast in such areas.
C.The waters in these areas were suitable for sharks to live in.
D.They were well-developed areas with strict environmental laws.
(　)7.What can be inferred from the last two paragraphs
A.Humans and animals coexist in ecosystems.
B.Overfishing is a contributing factor to the decline of sharks.
C.It’s uncertain whether humans cause the decrease of sharks.
D.Distances between reefs affect the number of shark species.
(　)8.What’s the text mainly about
A.A sharp decline of reef sharks.
B.Possible recovery of reef sharks.
C.Global cooperation of ocean protection.
D.Amazing discovery of coral reefs.
