本文的语篇类型为说明文。它主要是对客观事物或事理的介绍说明，与记叙文、议论文相比，说明文更强调科学性和客观性。本文围绕“鲨鱼是危险的动物还是濒危动物”这一问题进行客观讨论，进而引发人们对保护海洋动物这一话题的关注。
本文第一段为引子，以“the 1975 film Jaws”导入说明对象，第二段接着讲该电影对鲨鱼的影响，故一、二段为一个独立部分，讲述“sharks are dangerous”；第三段用表示时间顺序的词“After 1975”引出捕杀鲨鱼的后果，第四段以1980年Peter Benchley的经历说明人们开始意识到捕杀鲨鱼的错误，故三、四段为一个独立部分，讲述“sharks are endangered”；最后一段描述保护鲨鱼的现状“Today ...”。全文有明显的时间线，因此是以时间顺序来行文的。
(一)赏开篇之亮
1．“SHARKS: DANGEROUS OR ENDANGERED？”本文标题直接点明了文章的主题，即人们对鲨鱼的两种观点，同时引发读者思考。DANGEROUS和ENDANGERED是同根词，意义上却有巨大的反差，从而使得标题醒目且能吸引读者。
2．本篇文章采用了场景式开头，即开篇描述了电影《大白鲨》的一段惊悚镜头，渲染了背景氛围，且有助于吸引读者并导入话题。
(二)赏用词之妙
1．Jaws was a great success, attracting huge audiences and winning many awards.
赏析：本句中的huge audiences和 many awards形式对称，huge和many均强调数量之多，从而凸显了《大白鲨》这部电影取得了巨大成功。另外句中的success意为“成功的人(或事物)”，为抽象名词具体化，其前需加冠词；success表示“成功”时为不可数名词。
2．People just wanted them killed.
赏析：本句中的副词just着重强调了人们想要杀死鲨鱼的错误意识，just用来强调程度。常见的程度性副词还有：much, little, very, rather, so, too, quite, perfectly, enough, extremely, even等。
3．He came to see people as a danger to sharks, rather than the other way round.
赏析：本句中的“rather than the other way round”照应前半句中的“see people as a danger to sharks”，表示与其截然相反的情况，表达简洁又暗含强烈的谴责之意。
①Taking everything into consideration, ________________________________.
总的说来，这项活动非常成功。
②I waited an hour ____________________.
我等了一小时就是为了见你。
③All in all, young people should be forward looking ____________________________.
总而言之，年轻人应该往前看，而非对过去一直留恋。
(三)赏句式之高
1．Many people who saw the film started to believe that sharks were bad animals that ate humans.
赏析：本句中使用了两处定语从句分别修饰Many people及bad animals，解释说明了是许多看过电影的人认为鲨鱼是吃人的有害动物，从而让表达更具体、更精准。
2．Fortunately, not everyone who watched the film Jaws became afraid of sharks — some became interested in understanding them.
赏析：本句中部分否定与who引导的定语从句相结合使用，说明了并非所有看过电影的人都害怕鲨鱼，然后运用破折号对这一观点做了进一步解释说明。
①Put simply, potential is your natural ability_________________ when you try hard enough.
简而言之，潜能就是当你足够努力时才可以开发的天赋。
②_____________________________ must often overcome many challenges along the way.
那些做出重大发现的人必定要经常克服前进道路上的许多挑战。
③But __________________ is happy about the new method of expression.
但并非每个人都对这种新的表达方式感到满意。
(四)赏逻辑之巧
1．第二段第一句“People have always been scared of sharks, but Jaws made things worse.”在文中起到承上启下的作用。既承接第一段，指出电影《大白鲨》强化了人们对鲨鱼的恐惧心理， 又引领后文，继续讲述人们的恐惧心理以及在这一恐惧心理的影响下对鲨鱼展开的猎杀行为。
2．本文按时间顺序展开，各段内容由表示时间顺序的词汇引领，如第一段中的1975，第二段中的At that time，第三段中的After 1975，第四段中的In 1980以及From that day on, 最后一段中的Today。这些时间线索词将整篇文章自然衔接在一起，实现了语意上的畅通，逻辑上的连贯。
地球——人类唯一的家园。关爱地球、保护环境，践行绿色生活，是我们义不容辞的责任与义务。与此同时，我们应该保护好动植物，与生物和谐相处，保持生物的多样性，维持自然平衡。这样才有利于人类健康发展，社会不断进步。
The world's animal populations have decreased by more than two-thirds since 1970, according to a recent research from the World Wildlife Fund (WWF)．
The London group provided information on 32，000 wildlife populations which included more
①
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 great 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 loss in the coming years.”
Wildlife populations in Latin American 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 since 1970. For example, one population of pink river dolphins in the Amazon River area of Brazil fell by 65 percent 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 thrive (蓬勃发展), 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 has a role in reversing these trends, from individuals to companies to governments. undoubtedly continue to fall, driving wildlife to extinction and threatening the wholeness of the ecosystems on which we all depend.
[阅读理解]

A．Illegal hunting.
B．Global warming.
C．Land use change.
D．Environmental pollution.
2．How is paragraph 3 mainly developed？( )
A．By listing data.
B．By telling a story.

Along the Ulungur River in Altay, the northernmost area of Xinjiang, lives a species of beaver.This animal, which feeds on the shrubs (灌木) that grow near the river, has a strong sense of territory (领地) and won't leave its surroundings easily.So if people ruin the river, the beavers' homes will be destroyed and they will no longer survive.But fortunately for these picky animals, they have a responsible protector, Beaver Princess, Chu Wenwen.
Chu had a very different childhood.She was introduced to the wild at the age of 2 by her father who is an animal conservationist.So when the other children were reciting ancient Chinese poems and English alphabet, Chu was working hard to remember the names of different animals and plants.So instead of being a white-collar worker after graduating from Beijing Forestry University, Chu decided to return home and follow in her father's footsteps.
In Chu's hometown of Altay, there are 466 species of wild animals and 74 state-protected ones living in the surrounding 110,000 square kilometers.In 2018, Chu founded the Altay Natural Conservation Association which is aimed at animal protection.
The first public project Chu started was for beavers.“We took the beavers as a priority because they were greatly endangered at that time，” Chu said.“The beavers, which can build dams, are known as ‘engineers’ in the animal kingdom.Their dams can change water levels, gather fish, attract birds to nest and bring insects，” Chu explained.
Chu developed the “Beavers Canteen” program which calls on people to donate to help plant a species of shrub that is an important food resource for the beavers.The shrub is also the building material of the beavers.The clever animal makes full use of it.

When you go on vacation next time, make sure to take lots of pictures of the wildlife you see. These photos can help save different types of wildlife because of a new field called “imageomies”. Imageomies uses computers to study pictures of wildlife and learn information from them.
Until recently, scientists didn't have the technology to analyze (分析) the data in wildlife photos. But now, machine learning and computer vision are helping researchers unlock valuable information hidden in these images.
There are platforms where people can share their wildlife photos, like eBird, iNaturalist and Wildbook. These platforms help scientists keep track of different species and create databases. If you have rare photos of wildlife, it's a good idea to share them on these platforms.
Scientists have limited time and resources to study all endangered wildlife in the world. By using artificial intelligence (人工智能) to analyze public photos, we can learn more about different species and their behaviors. This technology can even help us find things in photos that humans might miss.
It's important to use the collected information responsibly and protect it from poachers (偷猎者). If we do that, imageomies can not only help save wildlife but also contribute to other fields like medicine and agriculture.

Ⅱ.阅读七选五
Being eco-conscious (生态意识) doesn't have to stress you out or expand your budget.Learn how to be kind to the Earth while also enjoying life.Here are some small but significant steps you can take.
Go LED with your lighting.There are several benefits of switching to energy-saving light bulbs (灯泡)． 9 Though the upfront cost might be more than traditional bulbs, the average savings on LED bulbs is $75 a year.Plus, you won't be spending nearly as much time changing burnt-out bulbs as you used to: LED bulbs can last years or even decades, depending on the type you buy.
10 On those days when you're out of patience and low on time, don't blame yourself if you have to use paper plates and cups instead of your dishwasher — especially if you're hosting a large crowd. Generally, dishwashers are required to design to use no more than 5 gallons of water per cycle and 307 kWh/year. 11 So in this point, using recyclable paper plates can save more.
Turn off water when you are not using it.Every drop does count when it comes to water usage. 12 Don't ignore this little time.If everyone does in this way, we can save a lot of water every day.There is also great low-flow equipment for showers and toilets.But if you don't want to change them, you can just switch them off when you're not using them. 13
A．Don't always use paper plates.
B．One of them is saving money.
C．This is a good way to save water.
D．Don't feel guilty about using paper plates.

Along the Ulungur River in Altay, the northernmost area of Xinjiang, lives a species of beaver.This animal, which feeds on the shrubs (灌木) that grow near the river, has a strong sense of territory (领地) and won't leave its surroundings easily.So if people ruin the river, the beavers' homes will be destroyed and they will no longer survive.But fortunately for these picky animals, they have a responsible protector, Beaver Princess, Chu Wenwen.
Chu had a very different childhood.She was introduced to the wild at the age of 2 by her father who is an animal conservationist.So when the other children were reciting ancient Chinese poems and English alphabet, Chu was working hard to remember the names of different animals and plants.So instead of being a white collar worker after graduating from Beijing Forestry University, Chu decided to return home and follow in her father's footsteps.
In Chu's hometown of Altay, there are 466 species of wild animals and 74 state protected ones living in the surrounding 110,000 square kilometers.In 2018, Chu founded the Altay Natural Conservation Association which is aimed at animal protection.
The first public project Chu started was for beavers.“We took the beavers as a priority because they were greatly endangered at that time，” Chu said.“The beavers, which can build dams, are known as ‘engineers’ in the animal kingdom.Their dams can change water levels, gather fish, attract birds to nest and bring insects，” Chu explained.
Chu developed the “Beavers Canteen” program which calls on people to donate to help plant a species of shrub that is an important food resource for the beavers.The shrub is also the building material of the beavers.The clever animal makes full use of it.

When you go on vacation next time, make sure to take lots of pictures of the wildlife you see.These photos can help save different types of wildlife because of a new field called “imageomies”．Imageomies uses computers to study pictures of wildlife and learn information from them.
Until recently, scientists didn't have the technology to analyze (分析) the data in wildlife photos.But now, machine learning and computer vision are helping researchers unlock valuable information hidden in these images.
There are platforms where people can share their wildlife photos, like eBird, iNaturalist and Wildbook.These platforms help scientists keep track of different species and create databases.If you have rare photos of wildlife, it's a good idea to share them on these platforms.
Scientists have limited time and resources to study all endangered wildlife in the world.By using artificial intelligence (人工智能) to analyze public photos, we can learn more about different species and their behaviors.This technology can even help us find things in photos that humans might miss.
It's important to use the collected information responsibly and protect it from poachers (偷猎者)．If we do that, imageomies can not only help save wildlife but also contribute to other fields like medicine and agriculture.
5．How can imageomies help scientists study wildlife
A．By offering information from wildlife.
B．By analyzing the data in wildlife photos.
C．By analyzing the trend of human population.
D．By knowing the origin of biological processes.
6．What are the platforms where people can share their wildlife photos
