1 . Ever been hungry enough to eat a house? Now, you actually could.
Food waste is a big problem in Japan and globally. Japan produced around 5.7 million tons of food waste in 2019. The government plans to reduce that by around 2.7 million tons by 2030. Tokyo University researchers Kota Machida and Yuya Sakai have developed a way to transform food waste into cement(水泥) for construction use and more. This is the first-ever process created for making cement entirely from food waste. The researchers say their product is four times as strong as traditional concrete. This particular cement can be used to make things like tea cups or chairs as well. However, there’s one additional feature — it’s also edible(可食的).
Kota and Yuya are the intelligence behind the formation of Fabula Inc., a company with purposes of reducing food waste, and helping fight global warming.
As expected, something this unique took years to develop. It took a few attempts to find just the right process. Kota and Yuya created the unique technology while researching possible environmentally-friendly materials to replace cement-based concrete. Cement production accounts for 8% of the world’s carbon dioxide emissions.
After a few failures, they realized they could get the cement to bind(黏合) by adjusting the temperatures. “The most challenging part was that each type of food waste requires different temperatures,” Yuya said. So the researchers had to observe them and respond in time. In the experiments, Kota and Yuya have successfully made cement using tea leaves, coffee grounds, cabbage and even lunchbox leftovers.
Fabula Inc. is currently working to make tea cups and furniture, but Yuya is thinking a little bit bigger. Their product could provide relief in the form of edible emergency shelters in disaster ones. “For example, if food cannot be delivered to the people, they could eat makeshift beds made out of food cement,” he said. To eat the material, a person needs to break it apart and boil it.

4 . Are you a tea drinker? If so, you’re not alone. Every day around the world millions of cups of this popular brew are drunk, and it’s been that way for thousands of years. The oldest discovered tea is from the Han Dynasty, dating from 206BC to 220AD. But it’s thought that the tea trend really took off during the Tang Dynasty in the 8th Century, when it became China’s national drink. Now, Turkey, the Republic of Ireland and the UK are believed to be the biggest tea—drinking nations, per capita.
Tea is consumed in many ways-slurped, sipped or glugged. It can be poured from pots, infused or brewed in the cup using tea bags—and it’s this latter process that is causing concern. Research last year found some premium tea bags might be leaving billions of microscopic plastic particles in the cup. Scientists from McGill University in Montreal found that some ‘plastic’ tea bags shed high levels of micro plastics into water. However, The World Health Organization says such particles in drinking water do not appear to pose a risk.
Most tea bags are made from paper, with a small amount of plastic used to seal them shut— made from oil. This has led to debate about whether they can be recycled, but many are still composted. However, gardener Mike Armitage has told the BBC that the plastic contained in the soil could be washed into streams and rivers and ultimately out to sea.
Unilever, the owners of the tea brand PG Tips, said their tea bags are made with a small amount of plastic—used to seal them—and that they are suitable for composting. And the brand Yorkshire Tea said their bags do contain 25% polypropylene, but they were “actively developing plant—based and biodegradable alternatives”.
While tea bag manufacturers might be doing their bit to reduce plastic pollution, it could be a good time to switch your favourite beverage to coffee, or if that isn’t your cup of tea then try using loose-leaf tea, which can have a better flavour.

5 . Buying furniture is easier than ever. You can even order a new table and chairs online without ever leaving home. But did you ever think about how furniture is made? The process begins with trees but now researchers have found a better way: growing it in a lab instead of a forest. Instead of cutting down trees and adding to deforestation, Velasquez-Garcia said, “If you want a table, then you should just grow a table.”
The research group found a way to actually grow plant tissue (组织) — wood and fiber — in a lab that is similar to the way cultured meat is grown. While there is still a long way to go to actually grow a table, the team was able to grow structures from cells from zinnia leaves.
Making furniture and other items from biomaterials could eliminate cutting down trees in forests. “The way we get these materials hasn’t changed in centuries and is very inefficient,” said Velasquez-Garcia. “This is a real chance to avoid all that inefficiency.”
There are other benefits to using lab wood too. Lab grown wood can be handled to take on any shape — like 3 D printing — so it may be possible to build a table without glue or screwing parts together.
Beckwith, a mechanical engineering PhD student, was inspired by a visit to a farm to try to make land-use more efficient and environmentally sound. “That got me thinking: Can we be more strategic (战略上的) about what we’re getting out of our process? Can we get more yield for our inputs?” she told MIT News. “I wanted to find a more efficient way to use land and resources so that we could let more farmlands remain wild, or to remain lower production but allow for greater biodiversity.”
Today, the two largest uses of trees are to make wood products and paper. When new biomaterials become readily available, forests will lose their economic value and will be preserved for their environmental, health, and recreational value. These researchers, like Velasquez-Garcia, are speaking for the trees.

9 . Even if you live a green lifestyle at home，it's possible to ignore that travels may be harmful to the environment. Here are some steps you can take to reduce the harm that comes from traveling.
Make clear the environmental challenges. Every country has environmental challenges to deal with. For some，it is plastic bags，for others the amount of energy used on air conditioning or heating. Make sure you know them and act responsibly. Use water wisely，for example，when you are in dry countries.
| A．Be as green as you are at home. |
| B．Find eco–friendly accommodation. |
| C．Eat locally grown foods as much as possible. |
| D．Choose a green means of transportation. |
10 . The world is going through a basic transformation,which is changing the way we live, work and think. The Fourth Industrial Revolution is bringing dramatic change and giving rise to a future filled with exciting opportunities and new challenges. Together, governments and businesses must find solutions to society's most pressing needs—from creating a carbon-free economy to tackling population growth and urbanization.
In any period of rapid change there is a trend to look for a simple method,to greet the new things and replace the old way of doing things. But a closer look at the facts tells a different story. Complex problems require many solutions working in harmony to enable positive change.
The challenge for scientists and engineers is to provide solutions in fact, data and today's realities. And while technologies offer new tools to help uncover solutions, the process also requires hard work, imagination and lots of improvement.
Success rests on performing practical, realistic, long- term solutions that make the world cleaner, safer and more sustainable(可持续的).
The environment is a case in point. Much of the public debate has centered on the central role of renewable power sources in realizing a low-carbon energy future. While the industry is fully behind developing renewables, today we understand that a low or zero-carbon future depends on adopting a multifaceted approach.
We cannot control sunshine levels or decide when the wind blows, which means solar power and wind power generators will produce too much or too little energy at times. The transition to renewables needs to take account of serious considerations.
Batteries have been much discussed as a means of storing extra energy, but there are other choices. Power-to- X technologies enable spare energy created by renewables to be stored and redistributed when and where it is needed.
1. Which of the following best explains the underlined word“tackling" in Paragraph 1?| A．Caring about. | B．Dealing with. |
| C．Going through. | D．Suffering from. |
| A．Offer new tools to help uncover solutions. |
| B．Look for a simple method to face the future. |
| C．Find out ways to solve the problem. |
