1 . Throughout history, many species of animals have been threatened with extinction. When Europeans first arrived in North America, more than 60 million buffalo (水牛) lived on the continent. Yet hunting the buffalo was so popular during the 19th century that by 1900 the animal’s population had fallen to about 400 before the government stepped in to protect the species. In some countries today, the elephant faces a similar challenge, as illegal hunters kill the animals for the ivory in their tusks.
Yet not all animals with commercial value face this threat (威胁).The cow, for example, is a valuable source of food, but no one worries that the cow will soon be extinct. Why does the commercial value of ivory threaten the elephant. while the commercial value of beef protects the cow?
The reason is that elephants are a common resource, while cows are private goods. Elephants wander freely without any owners. The hunter has a strong motivation to kill as many elephants as he can find. Because illegal hunters are numerous, each has only a slight motivation to preserve the elephant population. By contrast, cattle live on farms that are privately owned. Each farmer makes great effort to maintain the cattle population on his farm because he harvests the benefit of these efforts.
Governments have tried to solve the elephant’s problem in two ways. Some countries, such as Kenya and Uganda, have made it illegal to kill elephants and sell their ivory. Yet these laws have been hard to put into effect, and elephant populations have continued to dwindle. By contrast, other countries, such as Malawi and Namibia, have made elephants private goods and allowed people to kill elephants, but only those on their own property.
With private ownership and the profit motive now on its side, the African elephant might someday be as safe from extinction as the cow. The ancient Greek philosopher Aristotle pointed out the problem with common resources: “What is common to many is taken least care of, for all men have greater regard for what is their own than for what they possess in common with others.”

4 . The rhino census (犀牛普查) is out, bearing good news for the greater one-horned rhinos! In September, 2022, the International Rhino Foundation (IRF) documented in a report that there is a baby boom in this population, representing an increase of 167 percent.
According to the report, there are a total of 4,014 greater one-horned rhinos living in India, Nepal, and Bhutan. Although this is positive news, their IUCN (International Union for Conservation of Nature) status still remains vulnerable.
In India alone, the home to 70 percent of the world’s greater one-horned rhinos, there was an increase of 274 rhinos since the last biannual census, according to the organization Rhino Review.
An important reason for this baby boom is the fact that Assam, India, has enlarged Kaziringo National Park, home to the world’s largest one-horned rhino population. The park went from 430 square kilometers to 1,040 square kilometers. This gives more breeding areas for the rhinos, and they are closed to visitors during breeding season.
India and Nepal are also protecting the rhinos by enforcing wildlife crime laws. To reduce rhino death by poaching (偷猎), the IRF donates vehicles and equipment, plus education including guard training and crime investigation.
The IRF data for other rhino species is not as promising, although the greater one-horned rhino numbers are encouraging for future conservation. According to the report, there is a decline in Sumatran rhinos, Africa’s white rhinos, while the Javan rhino population is stable and threatened by loss of habitat.
The State of the Rhino report offers hope for these other species. Given that the greater one-horned things were once close to extinction, with fewer than 100 living in the world, their recovery is incredible. This demonstrates that there are solutions when organizations and people work together. Let us hope that this successful rhino baby boom will affect other endangered wildlife species around the globe.

7 . Dogs may have earned the title of our best friends through their interactions with humans, but now researchers say these social skills could, be present shortly after birth rather than being learned.
To better understand the role of biology in dogs’ abilities to communicate with humans, the researchers studied 375 eight-week-old service dogs. They looked at how these dogs performed in a series of tasks designed to measure their communication skills. The puppies were still living with their littermates (同窝出生者) and had not been sent to live with a volunteer puppy raiser, making it unlikely that they had learned about his or her behavior.
In the first task, a person hid a treat beneath one of two overturned cups and pointed to it to see if the puppy could follow the gesture. Since dogs are good at using noses to find things a treat was also taped to the insides of, both cups. In the second task, puppies watched as the researchers placed a yellow, block next to the correct cup, instead of pointing to indicate where the puppy should look for the food.
The third task was designed to observe puppies’ tendency to look at human faces. The researchers spoke to the puppy in a voice people sometimes use when talking to a baby. They then measured how long the puppy fixed a stare on the human.
In the last task, researchers sealed a treat inside a closed container and presented it to the puppy. They then measured how often the puppy looked to the human for help in opening the container.
The study found that while many of the puppies were responsive to humans’ physical and verbal cues, very few looked to humans for help with the unsolvable task. Researchers said, “This suggests that while puppies may be born knowing how to respond to human-initiated communication, the ability to initiate communication on their own may come later.” The next step will be to see if specific genes that may contribute to dogs’ abilities to communicate with humans can be identified.

8 . When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

When I adopted him, he had been rescued from death inside a tightly tied black trash bag abandoned right beside a garbage truck on the road. An alert garbage man noticed the bag moving and used a metal rake (耙子) to tear open the bag to look inside. There was my shaking puppy dog. The rake damaged the nerves in his back so he limped a little, but he could run as fast as lightning.
For my dog’s first birthday, I entered him in a fun run sponsored by our local Society for the Prevention of Cruelty to Animals (SPCA). I’m not much of a runner, but the run was only 3 kilometers, so I thought it would be fun for both of us.
We practiced for weeks. On our practice runs, he was always eager to go and usually dragged me along behind him. I worked on his leash (拴狗链) manners so that he wouldn’t trip me on the big day. I felt we were ready for anything.
The fun run was downtown among the big buildings, so the noise of barking dogs all around us rose to a deafening pitch at the start of the race. My dog was frightened when the starting tone went off. He had trouble running in the right direction with all the confusion around us. Soon the runners began to thin out, and my dog was running straight and fast. We were passing people and making great time. I was dreaming of a gold-medal finish.
However, when we were six blocks from the finish, my dog suddenly stopped and dropped to the ground like a sack of potatoes. I almost dislocated my shoulder from the sudden stop as I was pulled backward by the leash.
He was lying flat on his belly with his head down in the middle of the crossroads. At first I thought something bad had happened to him. He was shaking and sobbing. I did a quick check and couldn’t see anything wrong. I tried to get him up, but he refused. The police officer doing traffic control impatiently signed me to move away so he could release the cars.

10 . Hardscaping refers to non-organic features of a landscape such as pathways, driveways, walls, steps, and other human-made structures. The three Rs, which are common to many sustainability efforts, apply to hardscaping: reduce, reuse, and recycle.
Reduce Runoff
You can reduce rainwater runoff by using permeable (可渗透的) materials that allow rainwater to get into the soil below.
Use Recycled Materials
Consider using materials that are recycled from reclaimed (再生的) concrete, glass, or other construction materials that might otherwise end up in a landfill.
Support Local Wildlife
With careful planning and action, you can enjoy the convenience brought by hardscaping and at the same time be considerate to the environment and local wildlife.
| A．Those materials are seemingly useless. |
| B．All these are essential to a healthy ecosystem. |
| C．They aren’t suitable for all landscapes, however. |
| D．Don’t forget there are creatures living under the top soil. |
| E．You can get such things from many landscaping suppliers. |
| F．Rainwater is an important source of our underground water. |
| G．Add “support local wildlife”, and you’re ready for sustainable hardscaping. |
