1 . In 2022, campaign group Fashion Revolution Chelsea dye a garden for its Chelsea Flower Show presentation. An ancient craft, natural dyeing is a practice whose time has come again, with hand tie-dyed fashion also making a comeback in recent years.

The revival has been encouraged by Covid lockdowns, “which allowed people to explore the craft at home, says natural-dyeing enthusiast and teacher Susan Dye. It’s unlikely, though, that the practice would have caught on in quite the same way if not for a continually growing discomfort about fashion’s heavy footprint. From carbon emissions to animal cruelty, fashion is under considerable inspection. “Put it this way, 97% of dyes used in the industry are petrochemically (石油化学产品) based,” says sustainable fashion consultant Jackie Andrews, who helped advise the UN Ethical Fashion Initiative. We’ve got net zero targets which mean we’re going to have to remove all those petrochemicals from the manufacturing cycle.

Fashion is a huge polluter. According to the UN Environment Program, the industry is responsible for up to one-fifth of all industrial water pollution—due to the fact that most clothes today are produced in poorer countries where regulation is weak and enforcement weaker. Waste water is dumped directly into rivers and streams, poisoning the land as well as the water sources of people and animals who rely on them.

It’s easy to see why someone who cares about people, planet and animals, as well as clothes, might turn to natural plant dyeing. From the beauty of the raw materials—often wild plants-to the property of only bonding with natural fiber like cotton and linen (亚麻布) from the minor footprint of recycling old clothing that has grayed or faded over time to the vibrant and long-lasting dyeing results, plant dyeing feels like a quiet act of rebellion. This is why, while beginners start with simply changing their clothes’ color, new worlds open. Many of today’s natural dyers grow their own dye plants, run local community workshops, and advocate for change in industrialized fashion systems and beyond.

2 . Earth Hour is organized by the World Wide Fund for Nature. It's a big event usually at the end of March every year. On this evening, people “go dark”.     1    

It's true that turning off lights for just one hour saves only a small amount of power.    2    On one level, joining in Earth Hour makes people think about the problem of climate change and what we can do in everyday life to protect nature.

But on another level, a large number of people’s acting together sends a powerful message to governments and companies.     3     They begin considering green issues when big decisions.

The logo(标识) of Earth Hour is “60+” .The number 60 is for the 60 minutes of Earth Hour.     4     In fact, people who join in Earth Hour say that taking part makes them want to do more for the environment.

    5     Musicians give concerts by playing acoustic(原声的) instruments instead of electric ones, and using candles instead of electric lights. Celebrity chefs have created special recipes for families to prepare and eat by candlelight. Tree-planting sessions, group walks and runs are also among the options.

3 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

6 . Growing up, my grandparents bought a second home among a small forest in Arkansas and would bring me there every single summer. I would spend a lot of time outside there following my grandfather around while he did yard work. We would collect cool-looking rocks and refill the hummingbird feeders.

I always remember my grandparents calling me over to the window when a deer family was in the yard or a few hummingbirds were at the feeders so that I could watch them. I would explore around in the yard by myself sometimes to look for interesting rocks and if I was lucky I would find a turtle. If I did find a turtle, my grandfather would put it in the kiddy pool for me to observe for a few minutes. I was always amazed by these creatures. After I finished observing the turtle, my grandfather would pick it back up and return it to the bush I found it in. I would watch in amazement as it slowly stuck its legs out and crawled back under.

I always felt very at peace at my grandparents’ home. It was quiet and full of interesting natural things I never got to see in Illinois. They disturbed the land around them as little as possible and didn’t see it as nuisance (令人讨厌的东西), rather a beautiful view.

As Aldo Leopold, an American scientist, puts it, we should take the time to appreciate and observe the natural world around us. When we do this, we find it brings us happiness and has a great value beyond just that of resources. Conservation(n.保护) of the natural world is important because we are dependent upon it for life. We cannot worsen such a bountiful provider at such a rate in which it will never return to anything like what it once was. Our experiences with nature are what will drive us to reach this conclusion, if only everyone took the time to really involve themselves in it.

8 . Professor Veena Sahajwalla, 2022 Australian of the year, has created a solution to our massive trash problem: waste microfactories. These little trash processors (处理器)—some as small as 500 square feet— house a series of machines that recycle waste and transform it into new materials with thermal technology. The new all-in -one approach could leave our current recycling processes in the dust.

In 2018 she launched the first microfactory, establishing a model of recycling that enables businesses and communities to develop commercial opportunities while addressing local waste problems. A second one began recycling plastics in 2019. Now, her lab group is working with university and industry partners to commercialize their patented Microfactory technology. “The small scale of the machines will make it easier for them to one day operate on renewable energy, unlike most large manufacturing plants. The approach will also allow cities to recycle waste into new products on location, avoiding the long, often international, high-emission journeys between recycling processors and manufacturing plants. With a microfactory, gone are the days of needing separate facilities to collect and store materials, extract (提取) elements and produce new products,” says Sahajwalla.

Traditionally, recycling plants break down materials for reuse in similar products-like melting down plastic to make more plastic things. Sahajwalla’s invention advances this idea by taking materials from an old product and creating something different. “The kids don’t look like the parents,” she says. Sahajwalla refers to this process as “the fourth R,” adding “re -form” to the common phrase “reduce, reuse, recycle”.

Professor Veena Sahajwalla’s programs help to develop innovation and promote cooperation with industry, ensuring that sustainable materials and processes become commercially practical solutions for dealing with waste.

Many strange things happened before Tangshan earthquake happened. The well walls had deep cracks. Some     1     (smell) gas came out of wells. Chickens and even pigs were too nervous to eat.     2     3∶42 a.m. on 28 July 1976, everything began to shake. It seemed as if the world     3     (come) to an end. Hard hills of rock became rivers of dirt. In less than one minute, the whole city     4     (lie) in ruins. Two thirds of the people died or were injured. Everything in the city was     5     (destroy). People were shocked at this and wondered how long the disaster would last.

The army organized teams to dig out those     6     were trapped and to bury the dead. Workers built shelters for     7     (survive). Fresh water and food were taken to the city. Slowly, the city began     8     (breath) again. With strong support from the government and the tireless efforts of the city’s people,     9     new Tangshan was built upon the earthquake ruins. It has proved that in times of disaster, people must unify and show the     10     (wise) to stay positive and rebuild for a brighter future.
