Many of us were raised with the saying “waste not, want not”. None of us, however, can
Any kind of waste is thoughtless. Whether we waste our potential talents,our own time, our
5 . Getting rid of(丢弃) old tyres(轮胎) has long been a problem. Every year many tyres are thrown. Some of the ways might be better than getting rid of them, but they are not especially green.
Energy recovery(回收利用) is one common way. This includes burning tyres to produce electricity, or as a way to provide heat for other industrial processes. But that produces planet-warming pollution. Tyres can be whole or broken in construction projects, such as repairing roads. There are, however, worries about chemicals from the tyres coming out and polluting the ground.
So some companies have begun exploring another pleasing idea. Since tyres are mostly made from hydrocarbons(碳氢化合物), it should be possible in principle to turn old tyres into environmentally friendly materials which can be used to run some cars they came from. One of the most thoughtful companies is based in Oslo, Norway. Later this year the company will start building a huge tyre-reused factory in Sunderland in northeastern England. In a couple of years, when the factory is fully operational, it will be able to turn 8 million old tyres into new products.
The process works by dividing a tyre into its three main parts. One is steel, which is used to support the structure of a tyre and which can be easily reused. The second is powder used to improve the continuous use of the tyre. The third is rubber. Some of that will be natural rubber from the rubber trees. The carbon black can be reused to make new tyres. That is of interest to tyre makers because it helps efforts to become carbon neutral(碳中和).

A.By giving an example. | B.By making questions. |
C.By following time order. | D.By comparing differences. |

A.Tyres can be divided into three parts |
B.A company built a tyre-reused factory |

D.Old tyres can become environmentally friendly materials |
6 . Want to eat healthy and also save the planet?
How do our food choices affect climate change?
Food production accounts for about 20% of greenhouse gas emissions worldwide.
In each of four food groups — protein, mixed dishes, dairy and beverage — researchers looked at foods that disproportionately contribute to greenhouse gas emissions that cause global warming.
Top foods to swap out
USA TODAY asked if there is one specific food (or food group) that would be most recommended to be swapped out of.
A.If universally adopted, the recommended changes would lower the nation’s dietary carbon footprint. |
B.The team then matched each of these environmentally unfriendly foods to a similar option with a far lower carbon footprint. |
C.The good news is that there are many options for small changes to make to reduce your carbon footprint and improve your diet. |
D.A drastic change in your diet isn’t necessary to make a significant difference. |
E.You don’t have to make these changes all the time to make a difference. |
F.This means that changing what we eat can reduce greenhouse gas and carbon pollution. |
G.If you are a person who make the changes that we propose, you’re likely to see the benefits you want. |
7 . Human activities are making the globe saltier, specifically in our soils, fresh water and air, according to a study released this week in the journal Nature Reviews Earth & Environment.
Salt pollution isn’t some flashy threat to our existence — like, say, a meteor hitting Earth — but the issue is gravely overlooked and is a “sleeping giant”, said Sujay Kaushal, lead author of the study. Over the past 50 years, salt have increased in streams and rivers as people have begun using and producing more salts. The team found that across the globe, about 2.5 billion acres of soil — an area about the size of the United States — have become saltier.
Most people think of salt as the white specks we put in our food or the salt in the oceans, chemically known as sodium chloride (NaCl). That sodium salt can also be found in detergents (去污剂), other household products and more, but there are many different salts, including calcium, magnesium and other ions used in additional products — and they’re all increasing in places where they don’t normally occur.
Salt is a natural and necessary component of Earth. The compound is brought to the surface slowly over long geological time scales, through natural processes such as weathering of sedimentary (沉积而成的) rocks. When exposed at the surface, the salt can mix with water, be transported into water or go into the air. Living organisms, from plants to people, take up small portions to help regulate daily functions. Excess salt hitches a ride with water molecules, entering soil and the oceans. But human activities have altered this normal salt cycle in recent decades, the team found. Agriculture, mining, construction, water and road treatment, and other industrial activities are increasing the salt in our ground, freshwater systems and air.
Before this study, scientists didn’t really know how much humans were changing salt concentrations around the globe. But the “magnitude to which we have altered one of Earth’s natural cycles is alarming,” said ecologist Bill Hintz, who was not involved in the research. He agreed with the study’s authors that these changes to the salt cycle are an existential threat to freshwater supplies.
1. The underlined word “flashy” in Paragraph 2 can best be replaced by ________.A.instant | B.serious | C.damaged | D.unsolved |
A.People can only have access to sodium salt in daily life. |
B.People intend to have a limited insight into salt. |
C.Additional products are supposed to be banned. |
D.Salts are increasing in the world scale. |
A.Forming as a compound — weathering of sedimentary rocks — consumed by living organisms |
B.Coming into being in Earth naturally — being brought to the surface — combining with water — entering soil and oceans |
C.Coming into being in Earth naturally — being transported to water and air — increased by human activities |
D.Forming as a compound — removing excessive salt — entering soil and oceans |
A.Inefficient. | B.Unreliable. | C.Brain-washing. | D.Ground-breaking. |

9 . Be Green
What does it mean to be green? “Green” is more than just a color. It also means taking special steps to protect the environment. Why green? Plants are green, and without them the Earth wouldn’t be such a lovely home for human beings. What can we do?
Reduce It!
Reuse It!
Sometimes people call our society a “throwaway society”. It means that we’re too willing to throw away old stuff (东西) and buy new stuff.
Recycle It !
Recycling has never been easier. Many communities will pick recyclable things up right in front of your house and some towns even make it a rule. Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper, etc.
Enjoy It!
It’s true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that’s ready for you to explore.
But before you travel the globe, take a look at your own backyard. Is there a spot where you could plant a tree or build a small fruit or vegetable garden?
A.Get out of there and get your hands dirty. |
B.Turn off the water when you’re brushing your teeth. |
C.When you use less of something, you do a good thing for the Earth |
D.More often than not, even if you no longer need something, someone else just might need. |
E.Here’s a four-step guide to being green. |
F.You can watch with pride as your tree takes root and your garden plants grow. |
G.You can start by visiting the naturally beautiful spots in your city. |
10 . Few sights fill you with nostalgia (怀旧) like the fireflies dancing at night.
Create a firefly habitat
Flashing lights are an important part in fireflies life. As the sun sets, male fireflies move around while flashing their lights to signal their interest. If a nearby female is interested, she flashes back from her position to the ground, and the males fly down to find her. “All of that has to happen for the next generation to survive,” says Lewis. “However, light pollution makes those scenes much harder to see. It’s like cutting a phone line. It really stops the romance.
Stop using pesticides (杀虫剂)
Using pesticides in your yard also poses an existential threat to fireflies, which are insects after all.
A.Reduce light pollution |
B.Make a fire in the open air |
C.Luckily, there are some solutions |
D.But these beloved insects are in trouble |
E.The living conditions of fireflies are getting better |
F.The biggest threat facing fireflies today is the loss of their habitats |
G.Most of the pesticides will kill less-beloved insects as well as fireflies |
