Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from text-books. Sam was a kind-hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn’t wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel(铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher’s command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle-aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.

Tiny sensors inspired by dandelion (蒲公英) seeds could be spread to the winds to help track of climate change and global warming.
As the climate crisis continues to strengthen, tracking changes in temperature and other environmental signals across a wide area is useful. But doing effectively requires distributing sensors throughout the environment, which can be time-consuming.
“We wondered whether it’s possible to build a system that can spread sensors in the wind, rather than having a person go out and place sensors alone, which can be dangerous in hard-to-reach places,” says Vikram Iyer at the University of Washington in Seattle.
Iyer and his colleagues used a laser-powered tool to make devices. Each one weighs 30 milligrams with a diameter of 28 millimeters, and has a number of small holes through which air can float in the air like dandelion seeds.
The devices carry tiny sensors, essentially a microcomputer powered by small solar panels that can send back signals to the researchers, who developed different types that can measure temperature，pressure，light and so on. A small capacitor (电容器) can store energy overnight or in cloudy conditions.
In all, the team tested 75 different designs before finding the right mix of variables. The final design can move through the air at 0.87 metres per second, travelling up to 100 metres in a mild wind when released from a drone (无人机). Real-world tests showed that the sensors can transfer data up to 60 metres.
“The production of the ‘seeds’ is especially interesting, so is the design of the electronic devices,” says Jonathan Aitken at the University of Sheffield, UK. “Both seem to be very strong to the natural environment.”
Aitken is also impressed by the range of the sensors’ communication abilities. “Plus the cheapness of the device, it means that it can be placed in large numbers, and the communication range makes this an excellent choice, especially within agriculture or disaster area monitoring,’’ he says.

5 . It’s been given the title “Asia’s water tower”: Sanjiangyuan, meaning “the source of three rivers”, is an area in Qinghai. It is the source of the Yellow River, Yangtze River and Lancang River.
The three rivers provide water for as many as 600 million people, or almost half the population of China. And yet, because of its weak ecosystem (生态系统) and human activities, the environment in Sanjiangyuan is becoming worse, putting the country’s water source at risk.
This is why China built its very first national park, the Sanjiangyuan National Park, to protect the sources in 2020. The park will also increase the area’s green coverage and become the home of many wildlife species.
Long before the decision to build the park was made, however, volunteers across the country had already started their own effort to protect Sanjiangyuan.
Take Ren Shihai for example, a 38-year-old volunteer from Beijing. Ren is a member of the Shan Shui Conservation Center, focusing on environmental protection in the Sanjiangyuan area. He joined a team of volunteers who taught at the No 2 Middle School in Zaduo county, in Qinghai’s Yushu. He said he got a feeling of happiness when students were very excited when he spoke about the rivers and mountains in Sanjiangyuan and why it was important to protect them.
Zhaxi Bading, a 13-year-old Tibetan student, said he learned something new in Ren’s class. “I know the rivers that run through my hometown but I didn’t know their effects on the environment of the lower reaches,” he said. “I’m proud that my hometown is beautiful, and I want to protect it.”
Now under the protection of our country, hopefully “Asia’s water tower” will still have that name for years to come.

| A．To protect the water sources. |
| B．To study the wildlife in the area. |
| C．To enlarge the area of green coverage. |
| D．To increase the number of wildlife species. |

8 . Over the past four decades, more than 450 butterfly species have been hit by the falling numbers. In the US alone, the number of monarch butterflies (黑脉金斑蝶) has seen a drop of 80%, from scientists recording millions of them in the 1980s, and only 29,000 in 2020. It’s part of a wider possibility across the insect group. In 2017, scientists in Germany raised alarm bells after finding that insects had fallen by more than 70% in 30 years.
For farmers, monarch butterflies pollinate (授粉) a very large percentage of food crops. It is very important t protect them because their disappearance could have a huge economic influence. Butterflies are also helpful in the coal mine for other insects, as it is easier for them to feel the environmental change. and relatively easy to record.
Leading environmental organizations have been working hard to find new ways of recording the number of butterflies. As of now, there is no long-term data to develop good protection methods. The scientists wanted to address the challenge that long term recording programs worldwide have faced: they are focusing on training locals as insect experts, which requires much money. They came up with a new method to the problem. In Yasuni National Park, they hired park rangers (护林员) who were trained and then carried out recording. The rangers were able to recognize butterflies with an 85% success rate, which is important for these kinds of recording programs to be successful.
Compared with other recording projects, this study represents a long-term solution. “Our method increases the chance of recording in the long term by reducing the money spent on it such as wages,” said lead author Maria Checa. “Furthermore, it also offers opportunities for public organizations to achieve their environmental goals.”

9 . For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside.
Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. When builders began making houses and offices, they did not want to waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also used man — made building materials which are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building green plants.
Scientists believe that a plant’s leaves absorb the pollutants (污染物). In exchange the plant lets out oxygen through its leaves. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants.
