4 . Much like our guts (内脏), cities too have various types of microorganisms (微生物) that grow in the environment. And, much like analyzing the microorganisms in our guts can show important details about our physical condition, doing the same thing with a city’s microorganisms can help us understand data on the kinds of bacteria and other small life forms that are living alongside urban people.
While it’s possible to use human researchers to collect data on a city’s microorganisms, that kind of field research can be costly, difficult, and time-consuming. In 2010, honeybees in Brooklyn visited a nearby cherry factory, producing bright-red honey. This caused researchers to examine what other things New York’s honeybees were bringing back to their hives. It struck the researchers that this might be an easier way to collect microorganisms than to search for them on subway poles or sidewalks. So in a new study, researchers decided to seek help from the honeybee, which spends its days exploring cities all over the world, to learn about the urban microenvironments.
The team analyzed hive debris (碎片) from around the world and had some interesting findings. In Sydney, the hive debris showed DNA from microorganisms that can break down rubber, while in Melbourne, a significant amount of DNA from eucalyptus, a kind of tree originally from Australia, appeared at the bottom of hives. And the hive debris from Venice had microorganisms commonly found in rotting wood.
The analysis of Tokyo hives not only found DNA from local unique microorganisms, but also showed the presence of a microorganism that can cause disease among humans. This finding led the team to believe that using bees to learn about urban environments might be a great way to track the spread of human diseases.
While the study is still at the initial stage and it remains to be seen whether honeybees will help scientists find diseases or help city planners make cities greener one day, the insects’ great promise as little research helpers is obvious.

7 . Researchers have designed a hand-held device that can obtain and change water molecules (分子) from the air into drinkable water using only surrounding sunlight as its energy source.
This atmospheric water harvester (大气层水分收集器) used an ultra-porous (超多孔的) material, known as a metal-organic framework (MOF). It can obtain water repeatedly in the hottest and driest place in North America, Death Valley National Park. The tests showed the device could provide clean water anywhere, addressing an urgent problem, as climate change speeds up drought conditions.
“Almost one-third of the world’s population lives in water-stressed areas. The UN predicts that almost 5 billion people on our planet will experience some kind of water stress for a significant part of the year 2050,”said Omar Yaghi. He is the Berkeley chemistry professor who invented MOFs and is leading this study. “It is very important to take advantage of a new source for water.”
Other kinds of materials, such as salts or hydrogels (水凝胶), cannot operate in extreme weather conditions in an energy-efficient manner. The new MOF-powered harvesters can be a powerful tool to address water shortage issues related to anything from drinking water to agriculture. This technology can also be used to obtain pure water in areas where water is plentiful but not clean.
It’s also extremely efficient at harvesting water, releasing 85 to 90 percent of the water it obtains. It harvested up to 285 grams of water per kilogram of the metal-organic framework in a day, the amount of a cup of water. It’s also smaller than the earlier type but it is even more energy-efficient. It produced 200 grams of clean water per square meter of water vapor, more than three times the water productivity rate of the earlier type.
There will likely be further developments in efficiency and size for this device. Yaghi said, “He can see one day the widespread adoption of household-based MOF-powered water harvesters and community-scale (社区规模的) water harvesters with the help of data science and machine learning. Those can be in kitchens or even next to air conditioners to supply homes with clean water for cooking and cleaning. And some companies are already working on this.”

8 . Forget about “military-style travel” during which people tend to visit as many places as possible in the least amount of time. A more relaxed and leisurely alternative, such as “Citywalk”, is becoming the norm among urban youngsters.
Unlike military-style travel, Citywalk is about wandering around a city on foot, feeling the atmosphere and finding unusual things that even a resident of the city might not have noticed before. It can be a special event where people start a journey led by tour guides or simply explore the streets.
Such walks generally avoid famous scenic spots and shopping centers, and take you to places where you can have real interactions with the local people, eat at small but authentic restaurants, and gain a deeper understanding of the history and culture of the city.
Citywalkers have shared their carefully planned routes on social media platforms. Their posts usually include how long the walk is going to take, and interesting places and restaurants along the way. Some posts are more like a food tour.
Nan Xi, who recently moved from Beijing to Shanghai, said “I think Shanghai is a city perfect for Citywalk. There are big trees along the streets and shops selling different products, which is ideal for couples and friends to walk together and take photos.” After several Citywalk experiences, she signed up for a two-and-a-half-hour Citywalk priced at 88 yuan per person. A tour guide narrated the history of the buildings and streets along the way. “If it were me walking alone, I would simply find the streets artistic, but the tour that day helped me gain a better understanding of how Western culture blends in with the local culture in Shanghai,” she said. Another surprising benefit of the walk was that she has made friends with two of her fellow walkers.
Lin Yi, a manager for an online platform for self-guided tours, said Citywalk can help travelers learn about local culture and live as local people do, feeling the vibes of a city. People who participate in Citywalks usually have similar tastes, and can have in-depth discussions with each other, he said.

9 . Three grade 11 students from Harbour View High School, Canada, wanted to convey their message of fighting climate change to a younger audience. So, they wrote a children’s book named Keeping It Cool as part of a project.
Upon receiving their first order of 12 copies, Claire Malco, the illustrator of the book, vividly recalls the moment when the realization struck. “I just sat there with my mouth open and was like, wow, this is actually happening,” Malco told CBC News.
Coauthored by Joanna Jackson and Olivia Jordan, the book employs age-appropriate analogies (类比), coupled with vibrant illustrations, to promote actions kids can take against climate change. To explain the concept of the atmosphere, for example, the young authors drew a bubble(气泡) around Earth throughout the story. They also call for actions, such as planting trees and vegetable gardens – explaining how plants absorb CO2 from the “bubble” atmosphere just like a vacuum cleaner (真空吸尘器). The book also tells kids how they can avoid polluting the bubble by trying to walk, bike or scoot instead of taking a car or bus.
“The entire second half of the book is just things kids can do without needing their parents’ support … We wanted it to be something that every kid could finish,” Jordan explained to CBC News.
On Earth Day, the students visited a local elementary school where they read their stories and facilitated discussions about the text with every grade 5 class. They spread awareness that, regardless of age, anybody can help make a positive impact on Earth’s climate.“Educating students was the intention when writing this book. Having the opportunity to present to 10 different classes helped us gain insight on how to better our presentation and content, as well as see the impact this book will have on students,” the students told Our Canada Project.
1. Why did the three students write Keeping It Cool ?| A．To change a younger audience. | B．To show their talent for illustrating. |
| C．To describe environmental problems. | D．To inform kids of handling climate change. |

| A．They discussed the text with 5 classes. | B．They wrote the book with the students. |
| C．They did a presentation in every class. | D．They inspired discussions about the text. |
| A．A news report. | B．A book review. | C．A children’s book. | D．A diary. |
