1 . Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December: Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario(情景) this century”.
A survey of scientists found that extreme weather events, food insecurity, and freshwater shortages might create global collapse. Of course, if you are a non-human species, collapse is well underway.
The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world's most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.
The international scholars’ warning letter doesn't say exactly what collapse will look like or when it might happen. Collapseology, the study of collapse, is more concerned with identifying trends and with them the dangers of everyday civilization. Among the signatories(签署者) of the warning was Bob Johnson, the originator of the “ecological footprint” concept, which measures the total amount of environmental input needed to maintain a given lifestyle. With the current footprint of humanity, “it seems that global collapse is certain to happen in some form, possibly within a decade, certainly within this century,” Johnson said in an email.
“Only if we discuss the consequences of our biophysical limits,” the December warning letter says, “can we have the hope to reduce their speed, severity and harm”. And yet messengers of the coming disturbance are likely to be ignored. We all want to hope things will turn out fine. As a poet wrote,
Man is a victim of dope(麻醉品)
In the incurable form of hope.
The hundreds of scholars who signed the letter are intent(执着) on quieting hope that ignores preparedness. “Let's look directly into the issue of collapse,” they say, “and deal with the terrible possibilities of what we see there to make the best of a troubling future.”

3 . As Shanghai prepared to introduce mandatory(强制的) garbage sorting on July 1, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.
A 15-second video of a game went on Chinese social media. In the video, players wearing VR(虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets(桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.
“As a Shanghai, I am in great need of this game. Maybe I won’t need to check how to categorize(分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often, ” said ZhouZhou, a young Shanghai. But some social media users in Shanghai have complained about the difficulty of sorting different types of garbage.
Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more effective method than using paper materials when training volunteers,” Wu said.
1. What is the purpose of the VR game?A.Just for fun. |
B.Teach students to sort garbage. |
C.Do exercise. |
D.Keep fit. |
A.It is too hard to sort garbage. |
B.There are too many people lining up. |
C.The VR game should be more interesting. |
D.There are more ways to use paper materials. |
A.successful | B.interesting | C.traditional | D.disappointing |
A.Young people like VR games more. |
B.Shanghai performs mandatory garbage sorting. |
C.Games were used to help young people sort garbage. |
D.Learning by playing VR games is practical for the young. |
President Xi Jinping has called for garbage classification to be accelerated nationwide to help save resources and protect the environment. All major cities are expected to start garbage classification this year, and the system should be completed and function well by the end of 2025.
Yet the reality seems remote from the vision. Take Beijing, an early bird in garbage sorting, as an example. Even if the capital’s residents sort their garbage at home and throw them into different trash cans as required, almost all household garbage, including kitchen waste, is mixed up and transported away by the same rubbish truck.
Now it is the time for the government to reform its garbage disposal( 处 理 ) policies to ensure the formation of a complete industrial chain on garbage collection and recycling. For example, the household garbage disposal fee should be charged according to the total weight of the garbage each home produces in one year.
If the policy is carried on, resources can be saved and the environment improved.

6 . If you really want to go green, here’s good news: eating green foods is good for you. The very foods with a high carbon dioxide cost — dairy products, processed snacks — also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruits, wholegrains, fish and lean meats like chicken — a diet that’s eco- and waistline-friendly. Eating green foods can be healthier and beneficial to the climate.
It may be hard to believe that a meal at McDonalds produces more carbon dioxide than that your trip to a faraway place produces. More than 37% of the world’s land is used for agriculture, much of which was once forested. Deforestation (砍伐森林) is a major source of carbon dioxide. The fertilizer (肥料) and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate.
The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent (相等的) amount of grains, fruits or vegetables. What’s more, the majority of cattle in the U.S. are fed on grains and the fertilizer used to grow grains creates separate environmental problems.
Focus on eating food lower on the food chain, with more plants and fruits and less meat and fewer dairy products. It’s simple. We can change today what goes into our bodies for the health of our planet and ourselves.
1. According to the passage, eating green foods will ______.A.protect the animals from being killed |
B.promote the development of agriculture |
C.help us lose weight and keep self-confidence |
D.be good for our health and make a change of the climate |
A.Deforestation. | B.Grains. |

7 . Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels(松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to show how these differences could affect the growth of black walnut(黑胡桃) trees. The black walnuts is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researches estimate(估计) that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
1. The study done by Rob Swihart and Jake Goheen is to ________.A.find out how squirrels collect walnuts |
B.learn squirrels’ influence on black walnut trees |
C.do something to get rid of squirrels |
D.save the forests in the American state of Indiana |
A.the way they gather the walnut | B.the time they have winter sleep |
C.the place they have winter sleep | D.the place they store the walnuts |
A.Agricultural in Indiana has been well developed. |
B.Gray squirrels will be replaced by red squirrels in Indiana. |
C.The spread of red squirrels will do harm to walnuts trees in Indiana. |
D.The government will take some measures to protect black walnut trees. |
8 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放)more than doubling during the 1992 to 2007 window.
So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
1. What does the author think of new devices?A.They are environment-friendly. | B.They are no better than the old. |
C.They cost more to use at home. | D.They go out of style quickly. |
A.To reduce the cost of minerals. |
B.To test the life cycle of a product. |
C.To update consumers on new technology. |
D.To find out electricity consumption of the devices. |
A.The box-set TV. | B.The tablet. |
C.The LCD TV. | D.The desktop computer. |
A.Stop using them. | B.Take them apart. |
C.Upgrade them. | D.Recycle them. |
9 . Old problem,new approaches
While clean energy is increasingly used in our daily life,global warming will continue for some decades after CO2 emissions (排放) peak. So even if emissions were to begin to decrease today,we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation.
When it comes to adaptation,it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard,but to a constantly shifting set of conditions. This is why, in part at least,the US National Climate Assessment says that:“There is no ‘onesize fits all’ adaptation.” Nevertheless,there are some actions that offer much and carry little risk or cost.
Around the world, people are adapting in surprising ways,especially in some poor countries. Floods have become more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His notforprofit organization runs 100 river boats that serve as floating libraries,schools,and health clinics,and are equipped with solar panels and other communicating facilities. Rezwan is creating floating connectivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level:his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.
Elsewhere in Asia even more astonishing actions are being taken. Chewang Norphel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers (冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel's inspiration came from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200,000m3 of water. Climate change is a continuing process, so Norphel's ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.
Increasing Earth's reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.
In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the lifegiving ice. The outcome is still far from clear. But the World Bank has included the project on its list of “100 ideas to save the planet”.
More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.
Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.
