Water shortage is knocking at the door. It is one of the
This is not just
2 . Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(缺乏). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks(滴水) in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

Our school held an activity on last Sunday because it was “Earth Day”. Hundred of students took part in it. I am one of them. First, the headmaster gave us a speech about how to protect earth—our home. Then we went hiking, this was about 15km. Although the hiking was very tired, none were left behind. It is no doubt that all of us like the activity. In the future, they will try hardly to protect the environment. We hope we will take part in more activity about caring about the globe.

I am Liu Ying, a high school student. Our school is built 50 years ago. It is very beautifully as you can find many of tall trees, flowers and green grass here. I am very proud of learn in such a school. However, it’s a pity that there is a lot of rubbishes at some corners. I think we can do anything. First, we must know the important of keeping the school clean. Beside, we should spend some time clean up every corner of the school every day. Last, we must remember that no matter where we find rubbish, it is our duty pick it up and put it into rubbish cans.
5 . University of Colorado Boulder researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing (捕获) heat-trapping gases from the atmosphere and turning them into beneficial substances, like fuel or building materials, meanwhile limiting global warming and avoiding disastrous impacts of global climate change.
The tool predicts how strong the bond will be between carbon dioxide and the molecule (分子) that traps it. It allows researchers to identify suitable molecular candidates to capture carbon dioxide from everyday air.
The goal of carbon capture and storage technology is to remove carbon dioxide from the atmosphere and store it safely for thousands of years. But while it has been in use in the USA since the 1970s, it currently captures and stores a mere 0.1% of global carbon emission (排放) annually. To help meet the goal of carbon emission laid out by the IPCC, carbon capture and storage would have to rapidly increase in scale by 2050.
Current industrial facilities around the world rely on capturing carbon dioxide from a concentrated source, such as emissions from power plants. While these methods can bind (凝结) a lot of carbon dioxide quickly and efficiently using large amounts of certain chemical binders, they are also extraordinarily energy- intensive. This method is also quite expensive at scale to take carbon dioxide and turn it into something else useful, such as carbonates, according to Luca, fellow-elect of the Renewable and Sustainable Energy Institute (RASEI). Using the tool would free carbon capture facilities from being tied to concentrated source, allowing them to exist almost anywhere.
Being able to easily estimate the strength of chemical bonds also enables researchers to identify which binders will be best suited and offer a cheaper alternative to the traditional method for capturing and converting carbon into materials or fuel according to Haley Petersen, co-lead author of the study.

6 . Ada Smith, chairwoman of a non-profit organization Protect the Earth, wore green for a special event with school children in New York on Wednesday. The 40-year-old woman stood against the cool weather in a long green coat that has been in her wardrobe (衣柜) for years.
She wore the coat for the first time in 2019 during her husband Bill Smith’s tour to a national environmental conference, and she put on it again in her classic sustainable (可持续的) style. Ada’s recycled outfit was perfect for the occasion, all about the environment.
Ada and Bill headed to the Central Park, where they spent time brainstorming ideas with students on how to deal with environmental issues. Ada said, “Education is such an important part of protecting our planet. We must inspire the next generation with the optimism, confidence and enthusiasm to chase those solutions and continue building a more sustainable future.”
Ada and Bill helped the students generate more than 60 ideas to help the environment. Ada said, “Young children already identify the climate as one of their biggest worries, and our organization aims to educate them that we can find the answers by working together.”
Their visit came ahead of an award ceremony, in which five winners will be announced in the first round of the environmental prize pioneered by Ada. Ada and Bill will appear at the ceremony on the next weekend, when they will walk the “green carpet” with activists committed to environmental causes.
Though their time with the children was part of a larger initiative, environmentalist Steve Johnson said, “They didn’t come there for a photo, but to sit, talk to and listen to kids. It is from the heart and people get that.”
1. Why did Ada wear green?| A．To show a different dressing style. | B．To make herself more attractive. |
| C．To make herself match the event. | D．To fight against the cool weather. |

8 . Tropical rainforests are disappearing at an alarming rate, and according to a new report by Rainforest Foundation Norway, humans are to blame. The world’s dependence on coal, farming, soy, palm oil and mining has resulted in two-thirds of Earth’s tropical rainforests being completely destroyed, and the remaining ecosystems being put closer to a tipping point (临界点).
Tropical rainforests once covered 14.5 million square kilometers of Earth’s surface, but now, just one-third of that remains undamaged. Of the original area tropical rainforests once occupied, 34% is completely gone and 30% is suffering from degradation. All that remains is roughly 9.5 million square kilometers, and 45% of that is in a degraded (恶化的) state, the report says.
Researchers blame human consumption for the loss. While agriculture has always been a driving factor of rainforest loss, the report said that energy consumption, international trade and the production of soy and palm oil, logging and mining have been the largest threats over the past century. A significant number of U. S. products rely on resources from tropical rainforests. The country heavily relies on palm oil, rubber and cocoa, all of which come from forests around the world. Oftentimes, these resources are harvested from illegally deforested lands.
Tropical rainforests are home to more than half of the Earth’s biodiversity and have more carbon in living organisms than any other ecosystem. Along with supporting significant animal life, tropical rainforests are also essential to slowing down global warming. “These highly specialized ecosystems are suffering from constant abuse, through our bottomless appetite for land and resources,” said Anders Krogh, who authored the report. “We expect that upcoming UN climate and biodiversity summits provide specific targets and measures to protect tropical rainforests.”
The researchers also believe that the loss of tropical rainforests puts the whole world at risk of future pandemics. “Massive deforestation (毁林) is violating nature’s natural virus protection systems.” Krogh said. “The consequences of COVID-19 should bring rainforest protection to the top of the agenda of all policy makers and world leaders concerned about preventing the outbreak of new pandemics.”

| B．To present the process of rainforest degradation. |
| C．To stress the role of rainforests in the ecosystem. |
| D．To explain the reason for the disappearance of rainforests. |

9 . What would you think if someone suggested pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation (毁灭) of the natural world, we aren’t so easily shocked. But we should be...or we’ll be in a lot of trouble.
Nature is shrinking by the day. Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing. And all in the name of progress. This is bad in itself, but it’s devastating for biodiversity.
Biodiversity refers to the variety of plants, animals and other living things which are all inter-connected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis (光合作用) by green plants. In fact, all life on earth exists thanks to the benefit of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.
The loss of biodiversity could be devastating. “It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O. Wilson, known as “the father of biodiversity”. He warned, “we are about to reach a critical point beyond which biodiversity loss will be unavoidable.”
But what can we do? The problem is that the concept of biodiversity is so vague. People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. The Guardian newspaper is trying to help. It has started the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity. This includes persuading the UK government to create a series of marine reserves to reverse the decline in sea-life caused by industrial fishing, banning the fishing sharks by the Japanese fishermen and stopping the killing of dingoes in Australia, among many other things.
There is a lot to do. And we’d better get a move on if we don’t want to end up with a planet that can’t support life!
1. What does the author want to tell us by the comparison in paragraph 1?| A．It is unreasonable to pull down Big Ben. | B．People take devastation of nature for granted. |
| C．The differences between Big Ben and nature. | D．The great trouble we have been faced with. |
| A．It doesn’t matter to reduce biodiversity. | B．People have done enough to preserve biodiversity. |
| C．The situation of biodiversity is very serious. | D．Biodiversity loss has become unavoidable. |

10 . The UK’s planned ban on sales of new petrol, diesel (柴油) or hybrid (混合动力) cars could start as early as 2032, Transport Secretary Grant Shapps has said. Last week, the government raised industry concern after bringing the date forward from 2040 to 2035 in order to hit zero-carbon emission targets. But Mr. Shapps told BBC Radio 5 live it would happen by 2035, “or even 2032,” adding there would be consultation.
The main car trade body had previously said the 2035 figure was “concerning”.
The government is setting out its proposals in a United Nations climate summit in November. A Department for Transport spokesperson said, “We are consulting on a range of possible dates to bring forward the end to the sale of petrol and diesel cars.”
“The proposal for this is 2035 — or earlier if a faster transition appears reasonable — as well as including hybrids for the first time.” The UK has set a target of emitting zero carbon by 2050. Experts warned that the original target date of 2040 would still leave old conventional cars on the roads 10 years later. Once the ban comes into effect, only electric cars will be available. Hybrid vehicles are now included in the proposals, which were originally announced in July 2017.
Despite this, Royal Automobile club spokesman Simon Williams said, “While the government appears to be constantly moving forward for ending the sale of new petrol, diesel and hybrid vehicles, drivers should not be worried about choosing a hybrid car now.” “They are potentially the perfect stepping stone for those who want to go electric but have concerns about range (续航), as they aren’t as expensive as a battery electric vehicle. At the moment, they give drivers the best of both worlds.”
How attached are British people to their petrol vehicles? How long until conventional cars go the way of steam engine cars and horse coaches?
1. What is the car industry's attitude towards the ban on the sale of conventional cars?| A．Ambiguous. | B．Indifferent. | C．Worried. | D．Approving. |
| A．To remove the concern of main car trade body. |
| B．To hold back the development of pure battery electric cars. |
| C．To hold a United Nations climate summit in November. |
| D．To meet the zero carbon emission target as planned. |
| A．It's still a wise choice to choose a hybrid car nowadays. |
| B．Battery electric cars should be widely used immediately. |
| C．Drivers should consider about range when choosing a car. |
| D．People should abandon petrol vehicles as soon as possible. |
| A．They will fall out of use some day. | B．They are as important as horse coaches. |
| C．They will remain as a family necessity. | D．They may increase your daily expenses. |
