1 . There are two distinctive types of electric buses making their way along Nanjing Xi Lu, one of Shanghai’s busiest roads. The first is a fleet of blue trolleybuses that serve bus route number 20, a line set up by a British-run transport company in 1928. They use poles to receive electricity from wires overhead and have kept the route running in this way for nearly a century. But while the historic electric buses are a reminder of Europe’s past technological innovation, the new buses traveling alongside them are symbols of China’s contemporary net-zero ambition. These modern electric buses powered by lithium batteries (锂电池) , were introduced in Shanghai in 2014. They offer a smoother ride, especially during starts and stops. Widely used across China, these buses are key to the country’s EV transition and are influencing the global shift towards green transportation.

The most recent data available shows that China in 2018 was still the second largest source of carbon dioxide emissions in the global transport sector, responsible for 11%, and behind only the United States, which accounted for 21%. After around two decades of government support, China now boasts the world’s largest market for e-buses, making up more than 95% of global stock. At the end of 2022, China’s Ministry of Transport announced that more than three-quarters (77% or 542, 600) of all urban buses in the country were new energy vehicles. The speed of this transition was remarkable.

So far, however, the Chinese cities with the most successful e-bus introduction — such as Shenzhen, Beijing and Shanghai — all have moderate weather and are relatively flat. To take its e-bus campaign to the next level, China faces challenges. For one thing, it is difficult to bring fleets to cities such as Hong Kong, which — like London — have double-deckers. These two-storeyed vehicles are “very hard” to electrify, because they are heavier, use more energy, and so need bigger batteries, reducing the number of passengers they can carry. Cold weather is a problem, too, as it can make a battery’s charging time longer and its range shorter. The reason China has not achieved 100% electrification for its buses is its northern regions, which have cold winters, says Xue Lulu, a transportation expert at the World Resources Institute China.

3 . The Yellow River is the cradle of China’s civilization. And flood control and prevention have always been key to the well-being of the people living along it. Now, scientists can better work on these issues by giving the river a digital twin.

The digital twin of the Yellow River uses various technologies, including big data, artificial intelligence, and the internet of things. Devices (设备) set up along the river collect and transmit information to the center. Based on the information, a 3D model of the river is presented on the computer screen. It’s like the Yellow River has a twin that reflects its real conditions.

One big breakthrough in the river’s digital governance (治理) is “smart stones”. According to Wang Qin, a lead researcher at the Information Center of Yellow River Henan Bureau, a smart stone is a water-proof stone-shaped device with chips, a battery, and a signal transmitter. They are buried in important dike (堤坝) locations to record and report the movement of dike stones. “Upon feeling movement of the dike stones, the smart stone sends an alarm to the center for quick response,” Wang said.

“In the past, researchers had to learn the conditions of the dike on the spot by themselves, putting their lives at risk,” said Zhao Xiao from the bureau. “Now the smart stones can do this for us, more safely, quickly, and accurately.”

And in the sky, drones (无人机) are flying. On the routes designed by engineers, the drones become expert patrollers (巡逻员) of the river, looking at its dikes and flood prevention projects. According to Shen Lin from the Yellow River Conservancy Commission, thanks to the drones, researchers at the command center can get first-hand photos and information. “Researchers then update the 3D model according to the changes the drones reported. The newly updated model helps us test our floodwater release plans in case we ever need to batten down the hatches (未雨绸缪), ”said Shen.

Under the water and up in the sky, intelligence systems are helping to protect the Yellow River Basin on all fronts. According to the Ministry of Water Resources, in the future, we can expect to see the construction of an even more comprehensive digital system for this important river.

Wetlands are the link between the land and the water. They are transition zones where the flow of water, the cycling of nutrients and the energy of the sun meet to produce     1     unique and special ecosystem     2     (characterize) by hydrology, soils and vegetation—making these areas very important features of a watershed. The water is often groundwater,     3     (spill) up from an aquifer or spring. A wetland’s water can also come from a nearby river or lake. Seawater can also create wetlands, especially in coastal areas that experience strong tides. Here is one in China.

The National Nature Reserve of Guangdong Nanpeng Islands in Guangdong Province was established in 2003. It     4     (cover) a total area of 35,679 hectares. It became the fifth national-level marine nature reserve in Guangdong, as well as the first one in the eastern region of Guangdong, in 2012. In 2015, it     5     (recognize) and included in the International Important Wetlands Directory.

The main focus of the reserve is to protect the unique underwater natural landscapes, the ecosystems of the nearby     6     (coast) waters, the rare and endangered marine animals, the various fish species and their habitats, as well as the marine biodiversity.

Researchers have discovered 1,308 marine species in the area, including 772     7     (economic) significant fish, shrimp, crab, mollusk, and algae species. The reserve is home     8     more than 21 identified rare and endangered wildlife species in water, among     9     nine species such as the Chinese white dolphin and the nautilus are classified as first-class protected animals at the national level, while     10     (variety) of other 27 species, such as the common bottlenose dolphin is classified as second-class protected animals.

7 . You are sitting in a restaurant and a server brings over a glass of water and drops a plastic straw (吸管) next to the glass. Any idea how many plastic straws are thrown away in the US everyday? Around 500 million! Plastic straws were the seventh most common type of litter found during beach cleanups this year! Last year, a diver diving in Australia collected 319 plastic straws in just 20 minutes. The next day, she returned to the same location and found another 294 straws.

Very few single-use plastic straws are recycled. They break down into tiny bits of plastic, and are eaten by sea life. Luckily, thousands of people have gotten involved (参与) with the cause, including kids!

In 2011, 9-year-old Milo Cress made an interesting observation after ordering a drink of juice in a restaurant, “I noticed the servers automatically placed a plastic straw by my drink.” Milo thought this was a real waste and thought there had to be something he could do about it. Milo talked with plastic producers to get an estimate of just how many straws we use. He learned that 500 million plastic straws are used every day! This inspired him to start a project called Be Straw Free. Milo encouraged restaurants not to hand straws out so freely. “Actually,” remembers Milo, “businesses liked the idea as it would save them money.”

Milo was one of many kids to become involved with the cause. Earlier this year, a group of third-and-fourth-graders from Seattle, Washington, spoke with local lawmakers about the harm plastic straws have on sea life and our environment. The group, calling themselves the Straw Kids, would like cities to ban their use, and would like other kids to rethink the use of single-use plastic straws. Megan O’Reilly, 9, says, “We are making a website, strawkids.org, which will help us get the word out that plastic straws are bad, and help us get more supporters.”
