A
Human is struggling to contain two major crises: Skyrocketing global temperatures and deep diving biodiversity(生物多样性)．But people tend to solve each problem on its own，for instance by using green energies and carbon eating machines，while surrounding ecosystems to preserve them.But a new report argues that treating each crisis in isolation(孤立地) means missing out on solutions that resolve both.Human can’t solve one without also solving the other.
So what might these solutions look like？Say，for instance，you turn a heavily logged forest into a national park.As the trees grow back，they would provide habitat for the return of animals.Letting a forest come back naturally，rather than planting trees of a single species to balance up some corporation’s carbon emissions(排放)，makes it recover faster.This is known as a nature based solution，a campaign that both absorb carbon and provides an extra ecological or economic benefit.
Stopping human’s attacks on ecosystems can also help fight climate change，the study’s authors write.Even cities can get in on the action，the report notes.Urban areas turn into “heat islands” because they absorb the sun’s energy during the day and slowly release it at night.They are therefore much hotter than surrounding rural areas.Planting more trees cools cities and provides habitats for birds and shade for humans，which will be even more critical as global temperatures rise.
The big threat，the authors stress，is that nature based solutions alone can’t stop climate change.As temperatures climb and droughts get more severe，it’ll be harder for forests，wetlands，and mangroves to survive，even with our help.First and foremost，human has to dramatically reduce its greenhouse gas emissions.“Nature is not going to save us，” the authors say.“We can only use nature to support efforts.”
“Still，governments and corporations are becoming more conscious of the importance of maintaining biodiversity while also fighting climate change，” says Beymer Farris，from the University of Kentucky.“As a professor who has been working in this for 20 years，I see a lot of hope，because I see a lot of change on the horizon.”
1．How should people deal with the two crises
A．By using carbon eating machines.
B．By giving priority to one of them.
C．By tackling them in the meanwhile.
D．By establishing more nature reserves.
2．What is the most effective way to stop climate change according to the author
A．Plant more trees in urban areas.
B．Adopt nature based solutions.
C．Send out less greenhouse gas.
D．Provide habitats for animals.
3．What is Beymer Farris’s attitude to the future of the ecology
A．Optimistic. B．Doubtful.
C．Critical. D．Concerned.
4．Which of the following is a suitable title for the text
A．Why We Care About Climate Change
B．How to Live in Harmony with Nature
C．Why Urban Areas Become “Heat Islands”
D．How to Protect Species and Save the Planet
B
China is showing the world its great resolve in the global climate campaign with concrete and self motivated efforts as well as serious commitment.
At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China’s plan made in June to cut its carbon emissions(排放) per unit of GDP by 60－65 percent from 2005 levels by 2030, and increase non fossil fuel sources in primary energy consumption to about 20 percent.
With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems.Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.
Actually, climate change efforts are already included in China’s medium and long term program of economic and social development, and ecological efforts are the clear characteristics in China’s 13th Five Year Plan(2016－2020)．
Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.
However，China’s development rights need to be respected.It is unfair to overstress China’s status as one of the world’s largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.
It is worthy of notice that China’s emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made one of the biggest producers of the gases.
To show its great resolve, Beijing in September also announced the establishment of an independent South South cooperation fund of ￥20 billion to help developing countries affected by global warming.
While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China’s commitment to fighting climate change and pointing fingers，and start shouldering their due responsibilities instead.
5．China is self motivated to transform its economic pattern in order to .
A．top the world
B．fight against climate change
C．solve its population problem
D．respond to pressure from developed countries
6．The underlined word “it” in Paragraph 7 refers to “ ”．
A．China
B．the United States
C．economic expansion
D．the population base
7．It can be inferred from the text that .
A．China will completely use non fossil fuels by 2030
B．China will carry out its plan by stopping its development
C．Chinese emit more greenhouse gases than Americans on average
D．some developed countries are not taking on their due responsibilities
8．Which of the following is a sign of China’s self motivated fight against climate change
A．Expanding its economy.
B．Using non renewable energies.
C．Making it part of China’s 13th Five Year Plan.
D．Donating money to developing countries.

How to Build a Natural Swimming Pool
Whether you like to practice your dolphin dives or lounge away the day on a raft，swimming is one of summer’s perfect pleasures.With a minimum of materials and without so many chemicals，you can create a cooling summer retreat in your backyard.
Though fairly common in Europe，natural swimming pools are in their early stage in the United States.You can ask most American swimming pool contractors to build a backyard pool._______The list may include rebar(钢筋)，gunite(水泥砂浆)，fiberglass，chlorine and an energy sapping filtration system.
But in recent years，a few builders and a growing number of homeowners have learned how to build pools. They’ve found it’s possible to construct pools that are more about building with nature and blending into the natural landscape.Natural swimming pools use gravel stone and clay in place of concrete or fiberglass，and aquatic plants instead of harmful chemicals and complicated mechanical filtering systems. They also support beneficial bacteria that consume debris and potentially harmful organisms，and give habitat to frogs，dragonflies and other water life.
A natural pool can be constructed for as little as $ 2,000 if you do it yourself，while conventional pools can cost tens of thousands of dollars.
Natural swimming pools that require no harmful chemicals are fairly low tech. You won’t have to drain the pool each autumn.Except for topping it off now and then，you’ll fill the pool only once.
A．The plants enrich the pool with oxygen.
B．Chances are that they will roll out a long list of goods.
C．You can make your pool as shallow or as deep as you want.
D．And once established，they call for only a bit of management.
E．It is the most ecological and economic way to build a conventional pool.
F．They don’t rely on a mass of manufactured materials and chemical additives.
G．The result is a beautiful and ecologically system that is relatively inexpensive to construct.
