2 . “I am not crazy,” says Dr. William Farber, shortly after performing acupuncture (针灸) on a rabbit. “I am ahead of my time.” If he seems a little defensive, it might be because even some of his coworkers occasionally laugh at his unusual methods. But Farber is certain he’ll have the last laugh. He’s one of a small but growing number of American veterinarians (兽医) now practicing “holistic” medicine-combining traditional Western treatments with acupuncture, chiropractic (按摩疗法) and herbal medicine.
Farber, a graduate of Colorado State University, started out as a more conventional veterinarian. He became interested in alternative treatments 20 years ago when he suffered from terrible back pain. He tried muscle-relaxing drugs but found little relief. Then he tried acupuncture, an ancient Chinese practice, and was amazed that he improved after two or three treatments. What worked on a veterinarian seemed likely to work on his patients. So, after studying the techniques for a couple of years, he began offering them to pets.
Leigh Tindale’s dog Charlie had a serious heart condition. After Charlie had a heart attack, Tindale says, she was prepared to put him to sleep, but Farber’s treatments eased her dog’s suffering so much that she was able to keep him alive for an additional five months. And Priscilla Dewing reports that her horse, Nappy, “moves more easily and rides more comfortably” after a chiropractic adjustment.
Farber is certain that the holistic approach will grow more popular with time, and if the past is any indication, he may be right: Since 1982, membership in the American Holistic Veterinary Medical Association has grown from 30 to over 700. “Sometimes it surprises me that it works so well,” he says. “I will do anything to help an animal. That’s my job.”

4 . Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s “eyes in the sky” technology to make sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.

5 . In the race to document the species on Earth before they go extinct, researchers and citizen scientists have collected billions of records. Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for detecting shifts in the number and variety of species in an area, a new Stanford study has found that this type of record is not perfect.
“With the rise of technology it is easy for people to make observations of different species with the aid of a mobile application,” said Barnabas Daru, who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences. “These observations now outnumber the primary data that comes from physical specimens (标本), and since we are increasingly using observational data to investigate how species are responding to global change, I wanted to know: Are they usable?”
Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns.
“We were particularly interested in exploring the aspects of sampling that tend to bias (使有偏差) data, like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it,” said Daru.
Their study revealed that the large number of observation-only records did not lead to better global coverage. Moreover, these data are biased and favor certain regions, time periods, and species. This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby. These data are also biased toward certain species with attractive or eye-catching features.
What can we do with the imperfect datasets of biodiversity?
“Quite a lot,” Daru explained. “Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places — and even species — that are not well-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image.”

8 . As Ginni Bazlinton reached Antarctica, she found herself greeted by a group of little Gentoo penguins (企鹅) longing to say hello. These gentle, lovely gatekeepers welcomed her and kick-started what was to be a trip Ginni would never forget.
Ever since her childhood, Ginni, now 71, has had a deep love for travel. Throughout her career (职业) as a professional dancer, she toured in the UK, but always longed to explore further. When she retired from dancing and her sons eventually flew the nest, she decided it was time to take the plunge.
After taking a degree at Chichester University in Related Arts, Ginni began to travel the world, eventually getting work teaching English in Japan and Chile. And it was in Chile she discovered she could get last-minute cheap deals on ships going to Antarctica from the islands off Tierra del Fuego, the southernmost tip of the South American mainland. “I just decided I wanted to go,” she says. “I had no idea about what I’d find there and I wasn’t nervous, I just wanted to do it. And I wanted to do it alone as I always prefer it that way.”
In March 2008, Ginni boarded a ship with 48 passengers she’d never met before, to begin the journey towards Antarctica. “From seeing the wildlife to witnessing sunrises, the whole experience was amazing. Antarctica left an impression on me that no other place has,” Ginni says. “I remember the first time I saw a humpback whale; it just rose out of the water like some prehistoric creature and I thought it was smiling at us. You could still hear the operatic sounds it was making underwater.”
The realization that this is a precious land, to be respected by humans, was one of the biggest things that hit home to Ginni.

9 . The Government’s sugar tax on soft drinks has brought in half as much money as Ministers first predicted it would generate, the first official data on the policy has shown.
First announced in April, 2016, the tax which applies to soft drinks containing more than 5g of sugar per 100ml, was introduced to help reduce childhood obesity (肥胖). It is believed that today’s children and teenagers are consuming three times the recommended level of sugar, putting them at a higher risk of the disease.
Initially the sugar tax was expected to make £520m a year for the Treasury. However, data of the first six months showed it would make less than half this amount. At present it is expected to generate £240m for the year ending in April 2019, which will go to school sports.
It comes after more than half of soft drinks sold in shops have had their sugar levels cut by manufacturers (制造商) so they can avoid paying the tax. Drinks now contain 45 million fewer kilos of sugar as a result of manufacturers’ efforts to avoid the charge, according to Treasury figures. Since April drinks companies have been forced to pay between 18p and 24p for every litre of sugary drink they produce or import, depending on the sugar content.
However, some high sugar brands, like Classic Coca Cola, have accepted the sugar tax and are refusing to change for fear of upsetting consumers. Fruit juices, milk-based drinks and most alcoholic drinks are free of the tax, as are small companies manufacturing fewer than 1m litres per year.
Today’s figures, according to one government official, show the positive influence the sugar tax is having by raising millions of pounds for sports facilities (设施) and healthier eating in schools. Helping the next generation to have a healthy and active childhood is of great importance, and the industry is playing its part.
1. Why was the sugar tax introduced?A.To collect money for schools. | B.To improve the quality of drinks. |
C.To protect children’s health. | D.To encourage research in education. |
A.They turned to overseas markets. | B.They raised the prices of their products. |
C.They cut down on their production. | D.They reduced their products’ sugar content. |
A.Most alcoholic drinks. | B.Milk-based drinks. | C.Fruit juices. | D.Classic Coke. |
A.It is a short-sighted decision. | B.It is a success story. |
C.It benefits manufacturers. | D.It upsets customers. |
10 . Is comprehension the same whether a person reads a text onscreen or on paper? And are listening to and viewing content as effective as reading the written word when covering the same material? The answers to both questions are often “no”. The reasons relate to a variety of factors, including reduced concentration, an entertainment mindset (心态) and a tendency to multitask while consuming digital content.
When reading texts of several hundred words or more, learning is generally more successful when it’s on paper than onscreen. A large amount of research confirms this finding. The benefits of print reading particularly shine through when experimenters move from posing simple tasks — like identifying the main idea in a reading passage — to ones that require mental abstraction — such as drawing inferences from a text.
The differences between print and digital reading results are partly related to paper’s physical properties. With paper, there is a literal laying on of hands, along with the visual geography of distinct pages. People often link their memory of what they’ve read to how far into the book it was or where it was on the page.
But equally important is the mental aspect. Reading researchers have proposed a theory called “shallowing hypothesis (假说)”. According to this theory, people approach digital texts with a mindset suited to social media, which are often not so serious, and devote less mental effort than when they are reading print.
Audio (音频) and video can feel more engaging than text, and so university teachers increasingly turn to these technologies — say, assigning an online talk instead of an article by the same person. However, psychologists have demonstrated that when adults read news stories, they remember more of the content than if they listen to or view identical pieces.
Digital texts, audio and video all have educational roles, especially when providing resources not available in print. However, for maximizing learning where mental focus and reflection are called for, educators shouldn’t assume all media are the same, even when they contain identical words.
