Your Cat Might Not Be Ignoring You When You Speak

Every cat owner has a story to tell of being blanked by their cat. We call to our cat, it turns away, and some of us might be left     1     (wonder) why we didn’t get a dog. But your cat may be listening after all. More than that, it     2     (care) more than you may think.

A study by French researchers     3     (publish) last month in the journal Animal Cognition found that not only do cats react to what scientists call cat-directed speech — a high-pitched (高音的) voice similar to     4     we talk to babies — they react to who is doing the talking.

“We found that hearing their owners using a high-pitched voice, cats reacted more than when hearing their owner speaking normally to another human adult,” said Charlotte de Mouzon, an author of the study. “But it actually didn’t work when it came from a stranger’s voice.”

    5     studies involving dogs, analyzing cat behavior is difficult, which is part of why humans understand them less. Cats are often so stressed by being in a lab     6     meaningful behavioral observations become impossible. And forget about trying to get a cat     7     (sit) still for an M.R.I. scan (核磁共振扫描) to study its brain function.

So the researchers for the latest study went to the cats’ homes and played recordings of different types of speech and different speakers. At first, there was concern from Dr. de Mouzon and her team for lack of reaction from the cats, but upon analysis of the film recordings, delicate reactions     8     (notice). “It could be just moving an ear or turning the head to the speaker or even freezing what     9     were doing,” Dr. de Mouzon said.

In the study, there were a few cases     10     cats would approach the speaker playing a voice and meow. “In the end, we had really clear gains in the cat’s attention when the owner was using cat-directed speech,” Dr. de Mouzon said.

Japan Releases Nuclear Wastewater into the Pacific. How Worried Should We Be?

Japan has started releasing wastewater into the ocean. But this isn’t the kind of wastewater     1     flows from city streets into stormwater drains. It’s treated nuclear wastewater used to cool damaged reactors at the Fukushima Daiichi nuclear power plant,     2     (strike) by an earthquake over a decade ago.

Since the accident, over 1.3 million tons of nuclear wastewater     3     (collect), treated, and stored in a tank farm at the plant. That storage space is about to run out, the Japanese government says, leaving no choice other than     4     (begin) dumping the wastewater into the Pacific.

Japan’s discharge plan involves incrementally (递增地) releasing it over the next three decades, although some experts say it could take longer, given the amount still     5     (produce). Some of Japan’s neighbors are criticizing the plan as unilateral and dangerous. On May 15, South Korea’s opposition leader ridiculed Japanese leaders’ claims that the water is safe enough to drink: “    6     it is safe enough to drink, they should use it as drinking water.”

Now, American scientists are raising concerns that marine life and ocean currents could carry harmful radioactive isotopes (同位素) —also called radionuclides—    7     the entire Pacific Ocean.

“It’s a trans-boundary and trans-generational event,” says Robert Richmond, director of the Kewalo Marine Laboratory at the University of Hawaii. “    8     released into the ocean off of Fukushima is not going to stay in one place.”

The radionuclides could be carried by ocean currents, especially the cross-Pacific Kuroshio current. Marine animals that migrate great distances could spread them too. No     9    (worrying) as carriers, Richmond says, are phytoplankton—free-floating organisms that are the basis of the food chain for all marine life and can capture radionuclides from the Fukushima cooling water. When swallowed, those isotopes may “accumulate in a variety of fish, marine mammals, and humans.”

Richmond and Buesseler say that     10     they’ve been allowed access to much of the same data as the IAEA, they remain suspicious. “The root of this problem is that they are moving already with a plan that has not yet shown that it will work,” Buesseler says. “They’re saying, ‘We can make it work. We’ll treat it as many times as it takes.’ If you want to put a nickname on this plan, it’s ‘trust us; we’ll take care of it.’”

What Can One City Do?

People around the world are concerned about global warming and are talking about ways to stop it. The city of Cambridge, Massachusetts, in the United States, is doing more than just talking. Cambridge wants to become a world leader in energy-efficient buildings.

Today, Naema Omar is improving her 80-year-old house in Cambridge. To keep the heat inside in the winter, she is filling the space inside the walls with insulation(绝缘). Insulation is usually made from chemicals, but in her house, she is using     1     new - insulation made from recycled blue jeans and other clothes. She has also put in a new type of light called an LED lamp    2     uses only a tiny amount of electricity. The light-bulbs in it last for 20 to 30 years before needing     3     (change).

But eco-friendly insulation and lighting are much more expensive than the usual kind     4     many people in Cambridge can’t afford them. A group called Cambridge Energy Alliance (CEA)     5     (work) to solve this problem. They want to help every resident and business in the city conserve energy. People can ask the group to come and look at     6     they can make their house or office building eco-friendly. The CEA then makes them a plan to save 15 to 30 percent on heating, gas, water, and electricity. Then the group help people borrow money to pay for the improvements. The money that people save by being     7     (efficient) should be enough to pay back the loan.

It was ten years ago that the city of Cambridge decided to try to reduce its carbon emissions. More than 80 percent of the carbon dioxide     8     (produce) in Cambridge comes from buildings - not from cars     9     successful, the program will not only save a lot of energy but also make new jobs for local people. Workers    10     (need) to put in insulation, install better doors and windows, and make other energy improvements on buildings. The CEA hopes that their program will be an example for other cities.

Uber Eats pilots reusable container scheme

From today (Tuesday 18 April, 2023) Uber Eats customers in Central London will be given the option to order their takeaway in reusable containers and easily return them in an attempt     1     (address) single use packaging.

    2     (Bring) together various businesses, the project will test and measure how localized doorstep at-home collections of reusable packaging can increase the adoption rate of a reuse system and improve convenience. The system has been developed to make     3     as easy and convenient as possible for people to take part. When placing their orders, Uber Eats customers can choose to receive their food in reusable packaging. Once they’ve enjoyed their meals,     4     they need to do is to scan a QR code, select a day for collection, give the containers a simple rinse and await collection. All collections are low or no emissions,     5     (make) by deliverymen using bikes, electric cars or vans.

The trial will run for six months and will be managed by Again, which operates a network of packaging cleaning facilities     6     the reusable packaging will be cleaned and processed before being returned to the restaurants. Various promotions     7     (test) throughout the trial to measure opt-in rate and return rate. “This pilot aims to make reusable packing     8     (accessible) for customers and restaurants alike,” says Matthew Price, Uber Eats General Manager. “By integrating the reuse option     9     a delivery app used by many households and by offering doorstep collections, we hope to see a significant increase in the use of reusable takeaway packaging. The trial will help create     10     better understanding of what works and what doesn’t at a local level, and hopefully lead to wider roll out of this reuse system across more businesses and areas.”

Owning a Pet Is Good for Your Health

Pets in America are incredibly well loved: according to a 2015 Harris poll, 95% of owners think of their animal as a member of the family. About half buy     1     birthday presents. And it’s a two-way street. People who have pets tend to have lower blood pressure, heart rate and heart-disease risk than those who don’t. Those health benefits may come from the extra exercise that playing and walking     2     (require), and the stress relief of having a steady best friend on hand.

Scientists are now digging up evidence     3     animals can also help improve mental health, even for people with challenging disorders. Small     4     the studies are, the benefits are impressive enough that clinical settings are opening their doors to animal assisted interventions — pet therapy, in other words — used alongside conventional medicine. “    5     (think) of an animal in a hospital used to be one of the great no-no’s,” says Alan Beck, director of the Center for the Human-Animal Bond at Purdue University, citing the fear of causing infection. “Now, I don’t know of any major children’s hospital     6     at least some kind of animal program.”

The rise of animal therapy     7     (back) by increasingly serious science showing that social support — a proven antidote to anxiety and loneliness — can come on four legs, not just two. Animals of many types can help calm stress, fear and anxiety in young children, the elderly and everyone in between.

More research is needed     8     scientists know exactly why it works and how much animal interaction is needed for the best results. But     9     (publish) studies show that paws have a place in medicine and in mental well-being. “The data is strong,” Beck says. “If you look at     10     animals do for people and how we interact with them, it’s not surprising at all.”

Venice—The Risk of the Disappearance of an Entire City

Venice is a stunning oddity. It is a city built atop around 120 islands, crisscrossed by 177 canals, and is best explored via the use of its 391 bridges. But the city is not well recently. Indeed,     1     drastic measures are taken, the city’s days could be numbered.

This is far from hyperbole(夸张): Venice is at very real risk of     2     (consume) by the sea. In worst-case scenario, the city could disappear beneath the waves by 2100. Meanwhile, many of its building are sinking     3     being damaged by the wakes of boats. It is also routinely overwhelmed by tourists, while its local population is in continual decline.

Globally, a lot of cities    4     (hit) by similar problems of sinking land and rising sea levels in Venice. Low-lying Jakarta(雅加达), for example, is in such a terrible situation that it is being replaced     5     the capital city of Indonesia by Nusantara, a city not yet even built.

In November 2019, Venice suffered its second-worst flooding. It created headlines around the world, with onlookers     6     (astonish) by the incredible images of Saint Mark’s Square, one of the city’s lowest lying areas, covered in feet of water.

The tide reached a peak height of 187cm above sea level,     7     (result) in more than 80% of the city being under water. A state of emergency was declared, and there was an estimated €1bn euros worth of damage.

The worst ever flooding event, which happened in 1966,     8     (see) water levels rise to 194cm above sea level, and is thought     9     (damage) at least three quarters of the city’s shops, businesses and studios.

    10     a gap of over 50 years separated these events, recent trends suggest that we won’t have to wait half a century to see another disastrous flood. Since water levels started being officially recorded in 1923, they have reached 150cm or more on only 10 occasions, but five of those have been in the last three years.

Fresh warning sounded on plastics problem

Walk along any beach in the world, no matter how isolated, and you will see plastic of some kind washed up on the shoreline,     1    (offer) a reminder of the reckless throwaway culture of the present-day world.

Lately, a study     2     (sound) a fresh warning on the damage caused to the marine ecosystem due to discarded plastics, which eventually has a bearing on human health due to the seafood we consume.

In a paper     3    (title) “A Growing Plastic Smog” published on March 8, 2023 in the peer-reviewed research journal Plos One, researchers called on governments around the world     4    (take) sweeping action to address the “unprecedented plastic pollution” of the world’s oceans.

The plastics break down over time into minute particles that cannot be detected by the naked eye, but find their way into the marine ecosystem and into the seafood humans consume. No one knows for certain     5     the long-term damage will be to marine life and humans, but the study placed much of the blame on the plastics industry for failing to recycle or design for recyclability. “    6     eaten, microplastics can severely damage an animal’s internal tissues. Globally, we have reached a situation     7     we can no longer ignore the plastic pollution pandemic that is infecting our oceans,” he said.

“This research shows us that beach cleanups and citizen science projects that focus on the environmental fate of plastics have little impact on solving the enormity of the plastic problem. Marcus Eriksen, lead author of the study, said in a statement that the findings were a “stark warning     8     we must act now at a global scale”. “We’ve found an alarming trend of exponential growth of microplastics in the global ocean since the millennium, which     9    (expect) to reach over 170 trillion plastic particles,” said Eriksen, adding that the exponential increase in microplastics across the world’s oceans makes     10     necessary to “bring in an age of corporate responsibility for the entire life of the things they make”.

Parental Instincts

Last year in early summer, I was walking up the hill to my house in suburban Brisbane when I saw two birds, each about 6 centimeters tall, standing in my driveway. They didn’t seem to notice me     1     I was right in front of them and then they immediately scattered into the nearby bushes.

I was quite excited by the idea of two special birds     2    (make) a nest in my front yard, although I didn’t really expect them to as wild birds don’t usually nest so close.

A few weeks later, the birds reappeared. I found them crouching beside a tree off to the side of my driveway. As I approached them, I imagined that they’d run away like they did last time, but instead they     3    (stick) out their heads and made a threatening croaking sound     4     came from deep inside their throats.

I did some research and found that the birds are burhinus grallarius(长尾石鸻). I still didn’t know    5    they were croaking at me until a short time later I made an amazing discovery: they     6    (lay) two eggs which hatched into two small birds racing around now.

As I crept towards the birds, careful not to make any sudden movement, they started their croaking again,     7    (stretch) their necks forwards so they seemed longer and more threatening.

I was watching them in awe when I suddenly tripped and fell to the ground. The birds took this     8     a threat and the father raced towards me, spreading his wings to shield the mother and the chicks while making     9     appear larger.

I was sorry     10    (scare) them and left quickly.

I am amazed by their bold actions. Their parental instincts kicked in and made them so courageous. It is hard not to be awed by nature.

The Mystery is No Mystery

The area of ocean between Florida, Puerto Rico, and Bermuda, known as the Bermuda Triangle, is the source of much mystery. Over the centuries, reports of ships and planes disappearing     1     a trace have seized the public attention, leading the zone     2     (nickname) “The Devil’s Triangle.” Suggested causes for these mysterious disappearances range front supernatural powers to underwater alien bases. However, there is a more basic question to ask: Do more craft really disappear in the Bermuda Triangle than in any similarly trafficked area? The answer,     3     it turns out, is no.

The Bermuda Triangle covers a vast 700,000 square-kilometer swathe of ocean. Close to the equator(赤道)and near the United States, it is a particularly busy patch of sea with heavy traffic. According to Lloyd’s of London and the U. S. Coast Guard,     4     you were to compare the number of disappearances to the large quantity of ships and planes that have passed through the Bermuda Triangle, you would find that there     5     (be) nothing out of the ordinary about the area.

These days, new theories are being put forward, with a bit of scientific truth to them. Some have attributed Bermuda Triangle disappearances to explosive releases of methane (甲烷) gas,     6     (trap) as methane hydrate inside water molecules beneath the cold seabed of the deep ocean. Such blowouts could potentially release a giant amount of gas that could cause the sea to bubble like it was boiling, which could possibly sink ships because the resulting bubbles would be much     7     (thick) than the water on which large ships normally float. The gas could also rise into the sky,     8     (produce) a mixture of five to 15 percent methane which could explode on contact with the engine exhaust of a hot airplane.

The only problem with this theory is that scientists won’t be able to tell with much certainty if this is a factor       9     the ocean floor is mapped in greater detail. It remains to be seen     10     they will succeed in their attempt to clear up the Bermuda Triangle “mystery” this time around.
