3 . Approximately 5,000 juvenile individuals lose their lives on a daily basis due to diseases that are entirely preventable, such as cholera and dysentery. These illnesses proliferate when individuals consume or prepare food using contaminated water. The absence of clean water for personal hygiene also facilitates the transmission of entirely preventable conditions like trachoma, which has resulted in the loss of sight for an estimated six million individuals.
The scarcity of water resources also ensnares numerous households with limited financial means in a perpetual loop of economic hardship and suboptimal educational opportunities, with the most impoverished being disproportionately affected by the lack of access to water. Those who dedicate a significant portion of their daily routine to dealing with health issues, tending to ailing children, or traversing an average distance of 3.75 miles to gather water, are deprived of the educational and economic opportunities necessary to elevate their living conditions.
Agriculture is often referred to as the primary consumer of clean water globally, accounting for approximately 70 percent of its usage, while industrial applications require an additional 22 percent. Water bodies do not recognize political boundaries, and nations do not consistently collaborate in the equitable distribution of these shared resources, making water a frequent catalyst for international disputes.
The ongoing demand for water is steadily increasing, depleting sources from vast rivers to subterranean aquifers. As Postel remarked, “We are progressively incurring a greater debt in terms of our groundwater exploitation, which has profound implications for the security of our global water supply. The pace at which we are extracting groundwater has doubled since the year 1960.”
Some of the Earth’s groundwater is classified as fossil water, a resource that originated during a time when the planet's climate was vastly different from what it is today. Presently, such water is as finite as petroleum. “However, we are extracting a significant portion of these resources at an unprecedented rate,” Postel elucidated. “The escalating demand for water by humanity also poses a significant challenge concerning water and our ecosystems. This not only incurs a cost to the natural environment but also has long-term financial implications for future generations, including our offspring and grandchildren.”

4 . Students at Beijing’ s Yucai High School have to be very careful when playing football on the school’ s field. That’ s because there is a 100- year-old tree growing in the middle of it. And keeping their eye on the ball too much can result in a painful collision.
Building a football field around a tree sounds pretty stupid. But the school had no choice. It’ s reported that there are historic buildings all around Yucai High School, and this was the only space that could be used for a football field. Before starting working on the field, the school did ask to have the tree moved and planted somewhere else. However, they were told that it was hundreds of years old, and that it was a national treasure.
Having it moved and planted somewhere else was too risky—they might damage or kill the tree. So they were 1eft with no choice but to build the field around it.
Interestingly, Yucai High School is built on the grounds of Beijing’s Royal Gardens of the Ming and Qing dynasties. A reporter for the Beijing News believes that the strangely- located tree is the oldest tree in the Chinese capital. That information has not been checked, but other people think the tree is only 100 years old.
Playing a serious game of football on this field cannot be very pleasant. The tree could“catch” the ball and change its direction from time to time. But the students have no choice but to train on the playground with the tree. Luckily, they can play on a different field in competitions with other schools.
1. If students play football on the school field,________.| A．they might run into a tree | B．they will have a good chance of winning |
| C．they will fall down more often | D．they can control the ball all the time |
| A．Because the tree was as old as the school. |
| B．Because the school could only use that place. |
| C．Because students in the school liked the tree. |
| D．Because the tree had something to do with the city’s history. |
| A．Because there was no other place for the tree. |
| B．Because it may have been dangerous for the tree and it might have died. |
| C．Because the tree was too big to be moved. |
| D．Because it was more meaningful to keep the tree where it was. |
| A．It’s the oldest tree in the Chinese capital. |
| B．It was planted in Ming Dynasty. |
| C．Some believe it is only one-hundred years old. |
| D．Students will play on another field to protect it. |
5 . In some places around the world, you can find bright green balls of moss ( 苔藓 ) scattered across glaciers, which, surprisingly, move all at about the same speeds and in the same directions.
The glacier moss balls are commonly called “glacier mice”, and were the subject of a recent study published online in Polar Biology this month. The study’s authors believe that they develop from impurities ( 杂质 ) on ice surfaces. “They’re not attached ( 黏附 ) to anything and they’re just resting there on ice,” said one of the authors. “They’re bright green in a world of white.”
The moss balls don’t stay at rest for long, though. They moved about 2.5 centimeters per day on average. Another one of the study’s authors pointed out that movement is a necessity for the glacier moss balls because the entire surface of the ball must occasionally get exposed to the sun. “These things must actually roll around or else that moss on the bottom would die,” she said.
Glacier mice have ever been spotted in Alaska, Iceland, Svalbard and South America, but scientists still have a lot to learn about them.
One of the biggest questions is why the moss balls, which can live for at least six years, move the way they do. The researchers tried to explain this strange phenomenon in many ways.
First, they thought the balls had rolled downhill, but later found that they weren’t going down a slope ( 斜坡 ). Then, they thought the wind was blowing them in consistent directions. But when they measured the dominant direction of the wind, that didn’t explain it either. And finally, they considered the sun, which melts the ice and may make the moss balls move, but the direction of incoming solar radiation wasn’t in the direction which the balls were going in. Still confused with this problem, the researchers said that they hope that one day, future generations will “get to the bottom of these great mysteries”.

7 . In the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact (影响)on the environment. After all, you were jumping into your car, driving across town, coughing out emissions (产生排放)and using gas all the way. But now that we’re used to staying at home and streaming movies, we might get a little proud. After all, we’re just picking up our phones and maybe turning on the TV. You’re welcome. Mother Nature.
Not so fast, says a recent report from the French-based Shift Project. According to “Climate Crisis: The Unsustainable Use of Online Video”, digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would cause 3.5 pounds of carbon dioxide emissions. That’s like driving 3.9 miles. And in the European Union, the Eureca project found that data centers (where videos are stored)there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.
Streaming is only expected to increase as we become crazier about our digital devices (设备)and the possibility of enjoying entertainment where and when we want it increases. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world’s population will be online.
You’re probably not going to give up your streaming services, but there’re things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it’s also a good idea to stream over Wi-Fi, watch on the smallest screen you can, and turn off your Wi-Fi in your home if you’re not using your devices.

8 . This is a tale of two friends, Jia Haixia and Jia Wenqi-one is blind; the other has no arms. On their own, the two are“disabled(残疾的)". But together, they are a powerful team that has changed part of their village into a rich, green forest.
Their story began in 2000, when Haixia, who was already blind in his right eye, lost his left one after an illness. Wenqi lost his arms in an accident when he was just three. Neither could find a job, so the two decided to team up. They rented some poor land and began to plant trees. In return, the local officials paid them a small fee(费用). Haixia and Wenqi never imagined that they would end up creating an environmental paradise (乐园).
Their forest now has over 10,000 trees, hundreds of birds and many other wild animals. In addition, it saves the village from river flooding during the rainy season. When the friends work together, they focus on their strengths not their disabilities. Their day begins at 7 a.m. when the blind Haixia carries Wenqi across the river to get to their worksite.
Since they cannot afford to buy young trees to plant, the two use branches from existing (现存的) trees. Haixia climbs to the treetop and with Wenqi's direction, selects the perfect branch. He then digs a hole and carefully plants it. Finally Wenqi waters the area.
Though hard-working, the men don't make much money. But as Wenqi puts it,“We stand on our own feet so the fruits of our work taste sweeter."
Neither Haixia nor Wenqi cares about money.Together.hey already have everything they need—a perfect pair of eyes, two strong hands, and the best friendship in the world!

To support the activity name "Green Travel, Start with Me", I talk to my parents about my ideas. They were very supportive. They would not drive work from then on. In the following weeks, as they promised, I wen to school by bike every day, while my parents went to work by bus. Though we were tired, but we all felt happily. Last Friday, the class meeting was held. Some parents were invited, including my father and mother. We shared our thought during the meeting. All of us held the same view which environmental protection is so important for our life.
