1 . Most of us are familiar with Groundhog Day, wherein a large groundhog checks to see its shadow on February 2 and helps to predict when winter will end. But have you ever heard about how a mountain town in North Carolina uses a caterpillar (毛毛虫) known as the Woolly Worm to make similar predictions?
According to the folklore (民间传说), the amount of black on the woolly worm in autumn predicts the severity of the upcoming winter. The longer the woolly worm’s black bands (带) are, the longer, colder, snowier, and more severe the winter will be. Similarly, a wider middle brown band is associated with a milder upcoming winter. The position of the longest dark bands supposedly indicates which part of winter will be coldest or hardest. If the head end of the caterpillar is dark, the beginning of winter will be severe. If the tail end is dark, the end of winter will be cold. In addition, the woolly worm caterpillar has 13 segments to its body, which traditional forecasters say correspond to the 13 weeks of winter.
Scientific studies on worm forecasting are few and far between. The most often cited is a small trial that American Museum of Natural History entomologist Howard Curran conducted in 1948. Having heard about the caterpillar folklore, Curran traveled to Bear Mountain State Park to collect woolly worms each fall for eight years. He found that if the worms had brown markings on more than a third of their body, winters tended to be milder.
Most scientists discount the folklore of caterpillar predictions as just a folklore. “It’s a wonderful story, but I do think it was a playful trial,” says Joe Boggs, an entomologist at Ohio State University Extension who has studied woolly worms. “Curran was a real scientist. He had a bunch of papers published, but he never published this one—probably because he knew it wouldn’t stand up to peer review.”
Mike Peters, an entomologist at the University of Massachusetts, doesn’t disagree, but he says there could be a link between the band of a woolly worm and the severity of winter. Peters suggests that the timing of their growth and environmental conditions, such as temperature, moisture levels, and food sources, can impact the appearance of woolly worms, including their size, coloration, and band patterns. By analyzing these characteristics, researchers can potentially infer information about the weather conditions. “The band does say something about a heavy winter,” he says. “The only thing is that it’s telling you about the previous year.”

3 . In a groundbreaking achievement, a rhino has successfully undergone embryo (胚胎) transfer, marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.
The experiment, conducted with the less endangered southern white rhino subspecies, involved creating an embryo in a lab using eggs and sperm (精子) collected from other rhinos. This embryo was then transferred into a southern white rhino alternative mother in Kenya. Despite the unfortunate death of the alternative mother due to an infection in November 2023, researchers praised the successful embryo transfer and pregnancy (怀孕) as a proof of concept. They are now ready to proceed to the next stage of the project: transferring northern white rhinoembryos.
Professor Thomas Hildebrandt expressed optimism about the findings, highlighting the significance of the successful embryo transfer in demonstrating that frozen and defrosted embryos produced in a lab can survive. This development offers hope for the revival of the northern white rhino population.
However, challenges facing rhino conservation remain significant. While the southern white rhino subspecies and the black rhino species have shown signs of recovery from population declines due to illegal hunting for their horns (牛角), the northern white rhino subspecies is on the edge of extinction. With only two known members left in the world, Najin and her daughter Fatu, both unable to reproduce naturally, and the recent death of the last male white rhino, Sudan, in 2018, urgent action is needed to prevent the extinction of this subspecies. Dr. Jo Shaw, CEO of Save the Rhino International, emphasized the importance of addressing the primary threats facing rhinos worldwide: illegal hunting for their horns and habitat loss due to development. She stressed the need to provide rhinos with the space and security they need to succeed in their natural environment.
While the successful embryo transfer representsa significant advancement in rhino conservation efforts, organized action is required to address the main challenges facing rhino populations worldwide.

4 . The Coral Sea is home to an amazing variety of turtles, sharks, whales, dolphins, large fish, birds, corals, plants, and many other species. Many of these species are endangered elsewhere in the world, but still survive in the healthy environment of the Coral Sea.
The Coral Sea is a large series of coral reefs located off the northeast coast of Australia. This area is three times larger than Australia’s famous Great Barrier Reef, which the Coral Sea borders.
The Coral Sea is one of the few coral reef environments that have remained largely undamaged by overfishing, oil and gas exploration and pollution. However, statistics show that coral reefs around the world are disappearing five times faster than rainforests. It is very likely that in the near future the Coral Sea will face the same threats to its existence.
The Australian government is currently looking at options for protecting the Coral Sea but has made no decisions. Environmentalists are pushing for laws to declare the Coral Sea area a marine protected area. This would mean a large “no-take zone” for fishermen, a no-exploration zone for gas and oil companies and a no-dump zone for pollution. This would make the Coral Sea a marine park larger than any in the world.
We can write letters to Australian leaders, Australian environmental protection agencies, and Australian friends, to let them know that people worldwide support this protection of the Coral Sea. To lose this last great marine wildness would be a loss for the whole world.

5 . A grey-headed flying fox is back gliding through the night after life-saving surgery on a broken wing. The female flying fox’s wing was badly injured when it was twisted in a net placed over fruit trees in Geelong, Victoria. It was rescued and taken to Werribee Open Range Zoo’s veterinary hospital where it needed two operations to repair the wing.
Paul Eden, doctor of the hospital, said, “The flying fox was in a very serious condition when it arrived.” Flying foxes are highly dependent on their wings for many purposes. They can fly an astonishing 6,000 km in a year to search for food and pollinate a wide range of plants. They also use their wings to help capture insects, regulate body temperature and attract other flying foxes during mating season, So, it was extremely important that we did everything we could to help this animal make a full recovery. Vets operated to remove some of the flying fox’s damaged wing tissue and also gave it antibiotics (抗生素) and pain relief medication.
Following the successful procedure, the flying fox was transferred to a wildlife carer to prepare it for release back into where it belonged. Dr Eden said, “It is very rewarding to see the flying fox recover fully and safely return home.” According to researchers from Werribee Open Range Zoo, flying foxes played a critical role in Australia’s ecosystem, not only for the survival of other native animals but also humans. Our ecosystem would be dramatically different without flying foxes.
Dr Eden noted that there were some simple actions people could take to keep flying foxes safe, including reducing the risk of twisting by using nets with a size no bigger than 5 mm×5 mm when fully stretched over vegetable gardens or fruit trees. “If you encounter a flying fox that is sick or in distress, for the safety of everyone, don’t attempt to rescue the animal yourself. Instead, contact Wildlife Victoria who will send a trained officer to rescue the animal,” Dr Eden said.

7 . Going for a picnic is a good experience to be in nature, but it’s terrible to have a picnic that will do harm to the environment. Here are some ways to keep your picnic green.
Use reusable plates and cups. You don’t need to wash disposable (—次性的) plates and cups because they pollute the environment. It’s greener and cheaper to bring metal plates and cups from home. After the picnic, you can take them home and wash them.
Try to buy food from local farmers’ markets. In general, if you bring less food for your picnic, you’ll create less pollution.
Try to have an all-vegetarian picnic. Modern production of meat uses lots of energy and creates lots of pollution.
Instead of driving, ride a bike or walk to the park. If the park you want to visit is too far from your home, you can take public transportation like buses or subways.
After your picnic, remember to pick up all your trash. Try to keep the picnic area clean. If possible, try not to create any trash at all and reuse whatever you can.
1. It’s ________ to have a picnic that will do harm to the environment.| A．good | B．useful | C．bad | D．possible |
| A．Three. | B．Four. | C．Five. | D．Six. |
| A．Because they are very hard. |
