1 . How To Eat Better for the Planet
You are environmentally conscious and hungry. Here are answers to all your eco-friendly food questions.
Does what I eat have an effect on climate change?
Yes.
When forests are cleared to make room for farms and cattle, large stores of carbon are released into the atmosphere, which heats up the planet. Also, fossil (化石) fuels are used to operate farm machinery and ship food around the globe, all of which generate emissions (排放). Which foods have the largest impact?
Why does meat have such a big effect on the climate?
It’s often more efficient to grow crops for humans to eat than it is to grow crops for animals to eat and then turn those animals into food for humans. A conclusion was reached by the United Nations Food and Agriculture Organization in 2017.
Is there a simple food choice I can make that would reduce my climate footprint?
Consuming less red meat and dairy will typically have the biggest effect for most people in wealthy countries. A number of studies have concluded that people who eat a meat-heavy diet could reduce their food-related footprint by one third or more by moving to a vegetarian diet.
| A．Why do we need to change the climate |
| B．The world’s food system is responsible for it |
| C．The greenhouse gases have an impact on our food |
| D．How exactly does food contribute to global warming |
| E．Giving up dairy would reduce those emissions even further |
| F．On average, it takes about three pounds of grain to raise one pound of meat |
| G．In general, beef and lamb have the biggest climate footprint per gram of protein |

4 . We've got to do a better job of stopping global warming, a new report says.
The report, released Wednesday by the United Nations, says the world isn't doing nearly enough to control fossil fuel production to the level that's needed to stop "catastrophic" levels of global warming, pointing fingers at both developed countries and developing countries.
However, developing countries currently cannot sustain (维持) themselves, let alone grow, without relying heavily on fossil fuels. To them, fossil fuels are still the cheapest, most reliable energy resources available. India, for example, is home to one-third of the world's 1. 2 billion citizens living in poverty. That's 400 million people in one country without sufficient food or shelter. India hopes to shift to renewable energy as its economy grows, but the investment needed to meet its renewable energy goals “is over ten times the country's annual spending on agriculture and infrastructure (基础设施).” Unless something changes, developing countries like India cannot fight climate change.
Yet the weather changes and consequences of global warming, like tons of droughts and poverty are already impacting economic growth in many countries. Is there a solution?
According to a World Bank report, “poor and middle-income countries account for just over half of total carbon emissions.” And this percentage will only rise as developing countries grow. In Sub-Sabaran Africa, the number of people living in poverty increased by 98% in the thirty years, while carbon dioxide on average decreased by 17%. Given the current energy situation, if sub-Saharan Africans are to escape extreme poverty, they will have to increase their carbon use unless developed countries step in to offer clean alternatives and financial aid.
After all, global warming is, by definition, a global crisis. Reducing this threat will require global cooperation and global solutions.
1. What does the writer want to convey in paragraph three?| A．India has difficulty in feeding itself. |
| B．India has the largest number of poverty. |
| C．India cannot afford to develop clean energy. |
| D．India relies heavier on fossil fuels than USA |
| A．They'll be rid of extreme poverty. | B．They'll stop developing economy. |
| C．They'll care much for carbon emissions. | D．They'll pursue economic growth at heavy cost. |
| A．Poverty is the root of global warming. |
| B．Huge gap does exist between countries. |
| C．Developing countries cannot afford global warming. |
| D．Global warming demands global effort and solutions. |
| A．Conflicts between countries. | B．Ways of global cooperation. |
| C．Potential crises on the earth. | D．The importance of clean alternatives. |
5 . Open an app at your smart phone and scan the code bar on the garbage can. When you throw garbage into the garbage can, it will show the weight of the garbage and the points you can get from doing so.
In some cities, a variety of multifunctional smart garbage cans are being put into use. In Beijing, for example, a smart garbage can is equipped with an LED screen, which not only shows national policies on garbage classification but also shows the correct steps for garbage sorting. It can also calculate the weight of the garbage and the accumulated points one can get. They can be traded for some articles of daily use.
Garbage disposal is a small issue that involves everybody each day. However, it is also a big issue.
| A．Garbage sorting has been a new fashion. |
| B．Another kind of garbage can is even smarter. |
| C．It is no wonder that residents cheered for their presence. |
| D．Such a way of handling garbage has appeared in some cities. |
| E．It will affect China’s transformation towards green development. |
| F．Over 200 million tons of garbage is produced each year in some cities. |
| G．The good habit of garbage classification can improve the living environment. |
6 . The over 48,000 orange trees that are distributed at all corners of Seville, Spain, not only fill the city's air with the pleasant smell of their flowers in spring, they also produce over 16, 500 tons of fruit every winter. Though that makes the city Europe's top orange-producing city, the fruit is too sour to be consumed fresh. While some of the produce is used to make orange juice, most of it ends up in Seville's landfills. However, that may change soon thanks to a creative idea to use the oranges to produce clean energy.
In the pilot program, juice from 38. 6 tons of oranges will be left to ferment (发酵)in an existing biogas facility. The juice is fructose (果糖)made up of very short carbon chains, and the energetic performance of these carbon chains during the fermentation process is particularly high. The gas released from the fermented liquid will be used to drive a generator to produce clean power. The officials estimate the test run will generate about 1,500 kWh of energy—enough to run a water purification plant. "It's not just about saving money. The oranges are a problem for the city, and we're producing added value from waste,M said Benigno Lopez, the head of Emasesa's environmental department.
If successful, by 2023, the city hopes to recycle all the oranges and add the electricity generated back to its grid (电网). In trial runs, 1,000 kilos (2,200 pounds) of oranges produced 50 kWh of clean energy一enough to meet the daily electricity needs of five homes. The project team estimates that if all the fruit is recycled, it will produce enough energy to power as many as 73,000 residences.
The latest effort is among the many programs implemented in Spain to achieve the country's goal of switching its electricity system to renewable sources by 2050—and if everything goes according to plan, fully decarbonizing its economy shortly after that.

7 . Biofuels (生物燃料), gained from plants and animal matter, are a key solution to the environmental problems caused by fuels like coal. “Bioalcohol (生物酒精) is the most common biofuel and is produced by sugars found in materials such as corn. With some engine redesigned, it can be used directly by cars, buses, etc.,” says Professor Daniel Tan, “12 percent of transport fuel could come from biofuels, especially bioalcohol, by 2030.”
But a 2016 study of biofuels said, “Bioalcohol presently is mostly produced with food crops. Altogether, the environmentally-friendly biofuels rely on about 2-3 percent of the global water and land used for agriculture, which could feed a large number of hungry people.”
Energy experts have therefore been trying to deal with the problem. Recent research led by an international team found that the agave (龙舌兰) plant might offer a way out. This plant tends to be the right bioalcohol source to supersede others such as sugarcane (甘蔗) and corn.
Daniel Tan explains that the agave can be grown in unfavorable conditions and is not a major food crop. “It can grow in areas that lack water and rainfall without being watered by farmers, and it does not compete with food crops or put demands on limited water. This kind of useful plant is recently being grown in Australia. It can survive Australia's hot summers,” he says.
The study finds that sugarcane produces just a little more fuel per square meter each year than the agave. However, the agave outperforms sugarcane in a range of areas, including pollution to the earth, and water using. The agave uses 69 percent less water than sugarcane and 46 percent less water than corn for the same amount of fuel produced. As for corn，it produces less fuel per square meter each year than the agave.
However, Daniel Tan states: “The first generation of bioalcohol from the agave recently faces a big competition from oil, whose recent low price makes it far more attractive to customers. Without some policy support from the government, bioalcohol production from the agave faces big challenges.”

8 . Two women going on a journey to green their city is the best way to describe the founders of Utility, Portland's low-waste and reuse company. It started in January 2019 and opened its first retail shop in April. Its founders, Rebecca Rottman and Nadine Appenbrink, are deeply committed to sustainability and supporters of zero waste.
They started Utility as a second job for both and as a personal journey, looking for clean products that didn't come in plastic. Their goal is to reduce the amount of single-use plastics by allowing people to bring their own reusable containers when they buy environmental friendly home and personal care items.
Every week the women teamed up with local stores to sell their goods and to refill products for returning customers. Now they are operating only online for pickup or local delivery in the Portland area. It is really easy, the company said. Just shop online and choose a container. Then select pickup or delivery. The products include all-natural dish bar soap and a wide variety of plastic-free kitchen tools.
While not completely zero waste, Utility is striving to get extremely close. Appenbrink said, “We are all on a journey. And we want to be as approachable as possible. Utility is to raise awareness about this lifestyle.” They are focused on careful growth because Utility will never ship products because of the carbon footprint involved in shipping.
There are zero waste stores in other communities, like Clean Kilo in Birmingham UK, but they are real brick and mortar (实体的) buildings. Utility's concept is so simple that it can be followed almost anywhere. Zero waste markets are the way to the circular economy that is needed to stop plastic waste, reduce our carbon footprint and have a sustainable future.
1. Why did Rebecca and Nadine found Utility?| A．To satisfy people's basic needs. | B．To offer job chances to local people. |
| C．To raise money for a personal journey. | D．To promote the use of reusable containers. |
| A．Reducing their carbon footprint. | B．Offering more home-made products. |
| C．Providing low-price shipping service. | D．Expanding their market internationally. |
| A．It is a hard job to stop plastic waste. | B．It is easy to copy Utility's practice. |
| C．Zero waste stores should run offline. | D．Traditional shops produce more waste. |
| A．Two women are going on an eco-travel |
| B．Single-use plastics are replaced in Portland |
| C．A community online shop helps Portland go zero waste |
| D．A Portland company is changing plastic into green products |
9 . Calculated every year by Global Footprint Network（GFN），Earth Overshoot Day（地球生态超载日）is the day when human has used up all the natural resources—produce,meat,fish,water and wood.This means we use up them ahead of time before the end of the year.
It is just like spending your entire years' money by August and then borrow money from friends,knowing fully well you cannot pay back. GFN says the same thing happens in the case of the earth."Because we give out more carbon dioxide into the atmosphere than our oceans and forests can take in,and we harvest forests more quickly than they can regrow,"he said.
In a perfect world,we should only spend what we have.This means Earth Overshoot Day would fll on 31 December or perhaps in the following year. Unfortunately,the day has been climbing up quickly since 2014 when it fell on 19 August.In 2015,it was 13 August,and this year, the earliest so far—8 August!
According to GFN,Australia tops the list,with the United States coming in a close second.If the world's population started to live like either of these countries,we would need more resources to meet our needs.
Fortunately,experts say the situation isn't as bad as it sounds. Many countries have already taken measures to reduce carbon emissions（释放）by using wind or solar energy.People can also help by eating less meat, walking, cycling or taking public transportation,as well adopting the three Rs: Reduce,Reuse&Recycle.If we work together,we can help push back Earth Overshoot Day to December 31 or even beyond.
1. How does the author explain Earth Overshoot Day?| A．By giving us some data. |
| B．By comparing it to personal money. |
| C．By describing the process of waste. |
