In recent years, we have always seen different kinds of new energy vehicles on the road frequently, but do you know anything about them?
In the 21st century, with the increasing shortage of resources such as oil and natural gas, the issue of non-renewable resources has become a major concern. The traditional industry uses mostly oil as a fuel, and the carbon dioxide produced by burning oil hurts the air. The vehicle emissions (排放) contribute to global warming and other poisonous gases cause serious air pollution.
In response to the problem of vehicle pollution, countries and regions worldwide are setting increasingly strict standards for vehicle emissions. To cope with the increasing severity of vehicle emission standards, the major car manufacturers(制造商) are now mainly adopting methods to improve the technology related to the engines of conventional energy vehicles. Although this has improved the quality of emissions, it will be increasingly difficult to upgrade the technology. At this point, the development of new energy vehicles has become a new option for manufacturers, as the production and use of new energy vehicles will fundamentally solve the problem of vehicle emissions. Therefore, the development of new energy vehicles are a necessity and a general trend.
New energy vehicles are proposed as opposed to traditional vehicles, which are mainly fuelled by petrol. A new energy vehicle is a type of vehicle that runs on clean energy sources, using new energy sources as the fuel commonly used to power the car and provide the drive energy for the vehicle. New energy vehicles can be divided into several categories, such-as pure electric vehicles, fuel cell electric vehicles, hybrid (混合动力) vehicles, and so on. In addition, new energy vehicles have the advantage of low energy consumption and low-carbon environmental protection.
However, although new energy vehicles follow the concept of sustainable development, there are still many problems and challenges in the development of new energy vehicle research and production. For instance, many issues require specialist technicians and solutions, and further breakthroughs are needed in key technology areas. In addition, the efficiency of new energy use needs to be further improved, making it difficult to form an industrial-scale operation in a short period.

【推荐1】Have you ever wondered what animals are talking about? With the development of AI, we may be able to understand their languages!
In Professor Karen Bakker’s new book, The Sounds of Life: Hone Digital Technology Is Bringing Us Closer to the Worlds of Animals and Plants, she talks about how AI is helping us to make an animal version of Google Translate.
All around the animal kingdom, there are sounds that we can hardly pick up and understand. Elephants for example talk with each other using infrasound (次声波) —far below our human hearing range. Coral (珊瑚) in the ocean also sends sound waves to attract baby coral to safer areas to grow. This is surprising as coral doesn’t have any ears! Scientists have placed listening equipment into these environments to pick up the sounds humans cannot hear.
After the sounds are recorded, AI can study their meaning, according to the news website Vox. For example, Israeli researchers used AI to translate bats’15,000 calls. They found that more than 60 percent were arguments about four things: food, sleep positions, occupation of personal space, and unwanted advances.
This technology can not only understand the animals but communicate back to them. For example, bees use dances to communicate. A research team in Germany, therefore, put the bee language AI system into a robot bee. They asked the robot to create a dance route to tell the bees where the nectar (花蜜) was, Vox reported.

【推荐2】Artificial intelligence (Al) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer(癌症)in ways that were never before possible.
Rishi Rawat teaches Al at the University of Southern California's (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how Al and machine learning can more easily recognize cancerous growths in the breast. Rawat provides information about cancer cells to a computer. He says this data helps the machine learn."…You can put the data into them and they will learn the patterns and the pattern recognition. That's important to make decisions.”
David Agus is another USC researcher. He believes that "machines are not going to take the place of doctors." Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can't recognize these patterns by itself." Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Currently, researchers take a thin piece of tissue (动植物细胞的组织)，put it on a small piece of glass and add color to better see the cells .
That process could take days or even longer. Scientists say Al can do something better than just count cells. Through machine learning, it can recognize complex patterns or structures, and learn how the cells are organized. The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. "A11 of a sudden, we have the computing power to really do it in real time... We couldn't have done this, we didn't have the computing power to do this several years ago, but now it's all changed." Agus adds that the process could be done "for almost no cost in the developing world.” He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine .
The University of Southern California researchers are now only studying breast cancer. But doctors predict Al will one day make a difference in all forms of cancer.

【推荐3】If Siri had any feelings, she would know she was being teased. When 10-year-old Belinda and her friends play, they sometimes ask Siri questions in the hope she will say something random and make them laugh. “Do a rap,” they urge Siri, “Tell us a bedtime story.”
Belinda and her friends have grown up interacting with artificial intelligence(AI) in the form of Siri, Alexa and Google. They were born into a world of portable devices.
In 2010 when the first of their generation were born, Apple released the first iPad, internet activist Julian Assange published thousands of classified documents, Mark Zuckerberg was Time s person of the year.
Mark McCrindle, Sydney-based social researcher, first coined the term Generation Alpha to describe those born between about 2010 and 2024 in his book Generation Alpha. He said this generation have access to more technology? information and external influences than any generation before them, and at a younger age.
Belinda has had an iPad since year 3 and is allowed to use her iPad after doing violin and piano practice. "It's always 'Can I use my iPad, I'll do that afterwards7 and the afterwards never happens,” Catherine says, “Change the order and it gets done.”
Belinda is on guard against "stranger danger" and ensures her privacy settings, which mean that only her friends can join her in games. On occasion Belinda has wiped all her apps off her iPad, worried that she has disclosed too much, such as her date of birth and photo. When she downloads apps now she doesn't use her real date of birth.
In his book, McCrindle says, " In some ways, Generation Alpha are part of an unintentional global experiment in which screens are placed in front of them from the youngest age so we should pay attention to the addictive nature of devices and internet security."

【推荐1】It should be one of the main goals in today’s society to reduce plastic consumption (消耗). Though many believe recycling will solve the problems, and continue using plastic, it’s actually the opposite. In 2013, 254 million tons of trash were produced in the U.S alone, and only around 30% was recycled. This means the rest ended up in a landfill and will stay there for up to 1,000 years.
Recently, China has stopped importing trash from all over the world. Before this, over 30% of the world’s waste would end up in China causing a popular belief that Asian countries are those responsible for creating the majority of the waste in the world. Now, Asian countries, including Vietnam and Thailand, are looking for new ideas to avoid plastic. One of those ideas is a new, eco-friendly way to pack their goods by avoiding plastic packaging.
One of Perfect Homes Chiangmai’s team members noticed a creative way to reduce plastic that a supermarket called Rimping Supermarket was using and decided to shoot pictures of their shelves with his phone. Little did he know that people all around the world would absolutely love this idea. “I just dropped in to get a few items while we were waiting to sign some contracts (合同) with our lawyer, who was delayed. When I noticed the vegetables wrapped in banana leaves and simply liked the idea. So I took a few pictures and posted them online,” he said.
With more than 3.5 million views and over 17 thousand shares, the idea became something people can encourage more supermarkets to carry out.
Some have noticed that not everything on the shelves is completely plastic-free, to which the supermarket responded that they are taking one step at a time, but it’s not that easy. Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their produce in plastic since it is the cheapest and the easiest option.
It’s now up to the shoppers to show the supermarket which they prefer. If everyone chooses the banana leaf packaging, they will probably stop stocking the items in plastic.
1. What can we infer from paragraph 1?| A．Recycling has failed to solve the plastic problem. |
| B．Approaches to mountains of trash lack efficiency. |
| C．Trash shouldn’t be disposed of by burying alone. |
| D．Reducing plastic consumption is just impossible. |
| A．Rubbish export. | B．Acquiring technology. |
| C．Leaf packaging. | D．Convincing shoppers. |
| A．Disapproving. | B．Pessimistic. | C．Skeptical. | D．Supportive. |
【推荐2】In the Pacific Northwest, no tree is as crucial as the Douglas fir, which dominates the region’s rainforests. It was the basis of the traditional economy and is still an important source of timber (木材) in plantations around the world. But research now suggests the tree may be threatened with disease and decline, fuelled by a warming climate.
The cause is Swiss needle cast (SNC), a fungus (真菌) that grows only on Douglas firs. SNC can live on the tree kindly. Under certain environmental conditions, however, its activity intensifies, causing a yellowing and falling of needles that slows growth. In severe cases, it kills the tree.
Because our understanding of infection patterns is limited, researchers from the US Environmental Protection Agency and Oregon State University came together to reconstruct the conditions leading to outbreaks. In doing so, they found that the increasingly mild conditions expected with climate change will drive an increase in SNC disease.
The team took tree core (核心) samples from mature Douglas firs in different forests in Oregon’s Coast and Cascade mountain ranges. The growth rings in each core provided years of information, with sharp reductions in growth rate indicating SNC impacts. By combining the information collected from tree rings with information on climatic changes, the team found ties between climatic events and the intensity of outbreaks.
Periods with mild winters and more summer rain led to some of the most extreme SNC impacts. Similar climatic conditions are expected to become more frequent due to climate change.
Traditionally, SNC outbreaks have been more common in the mild, coastal fog zone than in the high Cascade peaks, but warming of these inland elevations will invite major outbreaks.
The effects of climate change are likely to extend beyond the trees, as they are vital to many animals, such as spotted owls, says David Shaw, a forest biologist at Oregon State University and director of the Swiss Needle Cast Cooperative. These threatened birds nest in bigger mature trees like Douglas firs. Slow growth from SNC may reduce nesting opportunities.
If, as feared, SNC outbreaks worsen and Douglas fir growth declines, Shaw expects broad and fundamental changes to Pacific Nothwest forests, including declining carbon fixation and lower timber harvests.
1. Under which of the following conditions will SNC’s activity intensify?| A．When Douglas firs’ needles fall down. |

【推荐3】The air is thin and we have to rest several times on the short hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the grassland in front of us, we can just make out a herd of graceful animals. This is why we’re here — to observe Tibetan antelopes.
Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai. Watching them move slowly across the green grass. I’m struck by their beauty. I’m also reminded of the danger they are in. They are being hunted, illegally, for their valuable fur.
My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Rcserve. It covers an arca of about 120,000 square miles. The reserve is a shelter for the animals and plants of northwestern Tibet. To Zhaxi, protecting the wildlife is a way of life. “We’re not trying to save the animals,” he says. “Actually, we’re trying to save ourselves.”
The 1980s and 1990s were bad times for the Tibetan antelope. The population dropped by more than 50 percent. Hunters were shooting antelopes to make money. Their habitats were becoming smaller as new roads and railways were built.
In order to save this species from extinction, the Chinese government placed it under national protection. Zhaxi and other volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.
The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the endangered species list. The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelope have not yet disappeared.
In the evening, I drink a cup of tea and watch the stars. I think about the antelopes and what Zhaxi told me. Much is being done to protect wildlife, but if we really want to save the planet, we must change our way of life. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.

【推荐1】Across Britain,burnt toast will be served to mothers in bed this morning as older sons and daughters rush to deliver their supermarket bunches of flowers.But,according to a new study,we should be placing a higher value on motherhood all year.
Mothers have long known that their home workload was just as heavy as paid work.Now,the new study has shown that if they were paid for their parental labours,they would earn as much as ￡172,000 a year.
The study looked at the range of jobs mothers do,as well as the hours they are working,to determine the figure.This would make their yearly income ￡30,000 more than the Prime Minister earns.
By analysing the numbers,it found the average mother works 119 hours a week,40 of which would usually be paid at a standard rate and 79 hours as overtime.After questioning 1,000 mothers with children under 18,it found that,on most days,mums started their routine work at 7am and finished at around 11pm.
To calculate just how much mothers would earn from that labour,it suggested some of the roles that mums could take on,including housekeeper,part-time lawyer,personal trainer and entertainer.Being a part-time lawyer,at ￡48.98 an hour,would prove to be the most profitable of the“mum jobs”,with psychologist(心理学家)a close second.
It also asked mothers about the challenges they face,with 80 per cent making emotional(情感的)demand as the hardest thing about motherhood.
Over a third of mums felt they needed more training and around half said they missed going out with friends.
The study shows mothers matter all year long and not just on Mother’s Day.The emotional,physical and mental energy mothers devote to their children can be never-ending,but children are also sources of great joy and happiness.Investing(投入)in time for parenting and raising relationships is money well spent.
1. How much would a mother earn a year if working as the Prime Minister?| A．￡30,000. | B．￡142,000. | C．￡172,000. | D．￡202,000. |
| A．emotional demand | B．low pay for work | C．heavy workload | D．lack of training |

【推荐2】“It’s raining cats and dogs!” Although this phrase is not very common in England any more, it clearly shows how we don’t always say what we mean. One thing that is often frustrating (灰心的) for language learners is that they understand every word in a sentence and yet the meaning remains unclear—like this sentence that actually means “it’s raining very heavily!” However, it’s not just idioms that cause difficulties for people learning English.
The British are often considered to be polite but this can be very confusing for non-native speakers. We often don’t say what we are thinking—in fact we often say the opposite! Here’s an example that will hopefully explain what I mean: “You should come round for tea!”
British people are less open than people from other cultures, so we aren’t as quick to invite people into our homes. This phrase is one of those that we say but often don’t really mean, so when no further details are given, you can probably assume (认为) it was made in the name of politeness! But how does this compare to other countries?
When I lived in India, lots of people would invite me into their homes but I always assumed that they were just being polite. Of course, I was wrong. The invitations were almost always genuine, and people expected me to visit them. I was always surprised by how welcoming people were. In fact, I think I spent more time at other people’s houses than my own!
In England, we often think it’s polite to offer or suggest something even if we don’t actually want to do it, while in other cultures people are more direct. Perhaps if English people just say what they were thinking, things would be a lot easier—especially for non-native speakers!
1. The example “It’s raining cats and dogs!” is mentioned to show that ______.| A．it is time for people protect these pet animals |
| B．the weather condition in England is rather awful |

【推荐3】Emerging economies (新兴经济) struggled to grow through the 2010s. People wonder how they will pay debts rung up during the pandemic and how they can grow rapidly as they did in the past — by exporting their way to wealth — in a new period.
The freshest of many answers to this puzzle is the fast spreading digital revolution. Emerging nations are adopting advanced technology at a lower cost, which is allowing them to fuel domestic demand and overcome traditional barriers to growth. Over the past decade, the number of smartphone owners has increased from 150 million to 4 billion worldwide. More than half the world’s population now carry the power of a supercomputer in their pockets.
Now, often by adopting rather than innovating, China’s emerging market peers are getting a push from the same digital engines. Since 2014, more than 10,000 tech firms have been launched in emerging markets — nearly half of them outside China. From Bangladesh to Egypt, it is easy to find companies who worked for Google, Facebook or other US giants before coming home to start their own companies.
In societies featured by bricks and-mortar stores (实体店) and services, customers are often comfortable with and slow to abandon the providers they have.
In countries where people have difficulty even finding a bank or a doctor, they will jump at the first digital option that comes along.
The “digital divide” is narrowing in many places. Last decade, the number of Internet users doubled in the G20 nations, but the biggest gains came in emerging nations such as Brazil and India.
The digital impact on productivity, the key to sustained economic growth, is visible on the ground. Many governments are moving services online to make them more accessible and less immune from corruption (腐败), perhaps the most feared barrier to doing business in the emerging world.
