3 . Dutch researchers have discovered that birds living in cities are using metal spikes (尖刺) to build their nests. People put these spikes on buildings in order to keep birds off their balconies, benches, and chimneys, but birds seem to be stealing them and using them to keep people away from their eggs.
The research began when, in the courtyard of a hospital in Antwerp, Belgium, biologist AukeFlorian Hiemstra found a large nest that had been built by a magpie (喜鹊). The nest was made from about 1,500 metal spikes. They were pointing outward to create a protective system around the nest.
“I just stared at it, this strange, beautiful, weird nest,” Hiemstra told BBC News. When he investigated further, he found that magpies had moved away nearly 165 feet of metal spikes that had been glued to the hospital’s roof.
After Hiemstra made this discovery, his team heard about a similar nest created by crows in Rotterdam, in the Netherlands, and another magpie nest in Glasgow, Scotland. The crows had positioned the spikes in a different way, perhaps using the metal to support the nest’s structure.
In their report, the researchers mention many kinds of birds moving spikes off buildings, but they chose to focus their study on corvids(birds from the crow family). The researchers pointed out that there have been previous studies on how corvids use everything from telephone wires to clothes hangers to build their nests. They said the use of anti-bird spikes “hints at a functional use”—meaning the birds seem to know exactly what they’re doing.
Magpies have often been seen nesting in thorny (多刺的) places, where the thorns can prevent people from attacking the small eggs and chicks inside the nest. Thorny hedges aren’t common in cities, however, so the theory is that magpies use the human-made version instead. Hiemstra calls this the birds’ “revenge”. “We’re trying to get rid of birds, but the birds are collecting our metal spikes and actually making more birds in these nests,” he said.

4 . Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims (声称) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your house is your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually frightened the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting (筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

5 . For long, Preifer Fall Trail (路线) was a most popular attraction in Big Sur. Annually, thousands of people hiked the trail. Unfortunately, the trail, along with stairs, signs, railings, an observation station and wooden bridges, was destroyed in the 2008 Basin Complex Fire. But now a new trail has risen from the burned land.
With its amazing rocky coastline and mountains, Big Sur, the writer Henry Miller once said, is “the face of the earth as the creator intended it to look.” But the landscape always suffers natural disasters. There have been three major wildfires in Big Sur in the past years. “You can still see the impacts there,” said John Hiles, a state parks repair team leader, pointing to black marks 30 feet up a huge redwood.
Parks planners designed a new track, moving the trail out of the river to reduce its impact on the environment. People from the California protection group, state parks department and the nonprofit organization put in 66,000 hours of work over the past four years. They built 160 redwood stairs and dragged hundreds of 16-foot-long redwood sticks by hand to build railings. They removed 4,150 square feet of old building stuff, enough to cover a basketball court. They used iron cables and pulleys (缆线和滑轮) to build a 70-foot long wooden bridge over the hills. “Nature is probably the best place to learn,” Hiles said. “More than any college or school, you learn so many life lessons out here.”
However, the huge Soberanes Fire s wept through the area in 2016, putting a stop to the work. When they began again in 2017, great river storms flooded the area and damaged part of Highway 1. Everybody gathered around this project. They saw the loss. They missed it. They wanted it to come back. They kept combining efforts. It’s been a long journey, but worth the wait.

7 . Human and their inventions, such as cars or plastic, have caused most environmental pollution on Earth. Today car emissions (排放物) are a major source of air pollution leading to climate change. In the meanwhile, plastics fill our ocean, creating a significant health issue to marine (海洋的) animals.
And what about the electric light, which is thought to be one of the greatest human inventions of all time? Electric light can be a beautiful thing, guiding us home when the sun goes down, keeping us safe and making our homes bright. However, like CO2 emissions and plastic, too much of a good thing has started to influence the environment. Light pollution, the wrong use of outdoor light, is affecting human health, wildlife behavior and our ability to observe stars.
Light pollution is a global issue. This became obvious when the World Atlas of Artificial Night Sky Brightness, a computer-created map based on thousands of satellite photos, was published in 2016, which can be viewed online. The map shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East and Asia are glowing (发光) with light, while only the most distant regions on Earth (Greenland, Central African Republic and Niue) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.
Sky glow is the brightening of the night sky, mostly over cities, due to the electric lights of cars, streetlamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.
People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers (宇航员) are particularly concerned with sky glow pollution as it reduces their ability to view stars.
Mostly over 80 percent of the world's population, and 99 percent of Americans and Europeans live under sky glow.

8 . El Nino is a weather pattern that brings hotter temperatures and less rainfall than usual. It is caused by warmer surface temperatures in the central and eastern tropical Pacific Ocean leading to a change in wind movements. Warmer ocean temperatures lead to more rainfall over that part of the ocean and less rain over Northern Australia.
An El Nino weather pattern has been declared in Australia for the first time in seven years and experts say people should get ready for extreme heat. The Bureau of Meteorology(欧洲气象局) said the country would sweat through hot and dry weather for the rest of 2023 thanks to El Nino and another weather pattern called a positive Indian Ocean Dipole, or IOD, which relates to ocean temperatures.
Both weather patterns have already brought hotter and drier weather to southern and eastern Australia while making heatwaves, droughts, bushfires and having effects on coral reefs much more likely.
Australia’s last El Nino was in the summer of 2015 before cooler, wetter La Nina weather took over. The Bureau said it was very likely El Nino would last the whole Australian summer.
“When a positive IOD and El Nino occur together, their drying effect is typically stronger and more widespread across Australia,” the Bureau warned.
The news comes after an unusually long period of warm spring weather, with some places recording temperatures 15°C higher than the average. A disastrous fire warning was announced for the NSW south coast on Tuesday as firefighters battled against the fire in the Northern Territory, Queensland and New South Wales.
Senior Leeturer in Climate Science at the University of Melbourne Dr Andrew King said the recent hot weather “is a warning of the kind of extremes we’re likely to see more of over the next few months”.
