Want to join the online fitness program
Online training is one of the fastest growing section of the fitness industry. A 2015 study found that more than half of all smartphone users had downloaded a fitness or health app. If you’re considering joining the online fitness community, consider these benefits and drawbacks.
There are many reasons that online training may work for you. As long as you have access to pre-downloaded videos or a WiFi connection for streaming videos, you can work out wherever you are.
Besides, compared with similar offline programs, most online fitness programs range in cost between $10 and $20 per month. This is due in part to the wider audience and the greater opportunity to sell programs to more people.
All this growth is incredibly positive — it provides health and fitness resources to the general consumer wherever they happen to be, without requiring access to a gym or fitness studio. But it’s not without problems.
The first thing to think about when considering an online fitness program is “know yourself.” If you struggle with self-motivation, you don’t like exercising at home, and you prefer a social workout environment, online fitness may not be for you. Not to mention the fact that very few online fitness programs enable the instructor to see you, check your form, and offer modifications or corrections based on your performance. This means you might perform exercises incorrectly, or even unsafely, without knowing it, which is particularly concerning for beginners and those recovering from injuries, as they’re more likely to perform exercises incorrectly.
Therefore, like any training format, there are pros and cons to consider when deciding if it is right for you. Take time and make the most suitable decision to reap more benefits.

The Paper Architect
For a long time, Zaha Hadid was known as “the paper architect,” someone whose grand designs never left the page to become real buildings. But in recent years her buildings have sprung up like mushrooms all over the world: the Guangzhou Opera House in China, a car factory in Germany, a contemporary art museum in Rome, a transportation museum in Scotland, and the Aquatics Center for the 2012 Olympics in London.
Pinning down her individual style is difficult. Certainly Hadid has been influenced by the modem trend in architecture that likes to play with the traditional shape of buildings and fragment (分解) them, creating unpredictable angles and surfaces. Working in this way, she and her fellow architects have produced some spaceship-like structures that seem to go against the normal laws of engineering.
The idea of offering the viewer multiple perspectives from within the building is a theme that runs through Hadid’s work. Her most famous building, MAXXI—a museum for the 21st century— in Rome, is a great example. It is a complex and spectacular structure of interlocking concrete shapes. Inside spaces interconnect Tike winding streets, so that the visitor is surprised and charmed at each turn. The Rosenthal Center in Cincinnati produces a similar effect. Like an extension of the street it sits on, it draws you in, with walkways directing you this way and that, and windows inviting you to sample the view. “It’s about promenading” says Hadid, “being able to pause, to look out, look above, look sideways.”
So what inspires someone like Hadid to produce such different buildings She speaks in complimentary terms about the work of her contemporaries. She also cites the natural landscape and organic geological patterns as an influence. But it is not a question that she seems too concerned with and nor perhaps should we be. Hadid is an artist, sharing with us her vision of what buildings should be like and always, as she does so, trying to keep human interests—our interests as users and viewers—at heart.

Men may eat more in summer
Winter may be seen as the time to fill up with food, but in fact, sunny summer months are when men eat more calories—unlike women.
The effect seems to occur because sunlight makes the skin release an appetite-stimulating hormone (激素), says Carmit Levy at Tel Aviv University in Israel. Levy and her colleagues noticed the effect in experiments in mice, in which male animals exposed to UV light (紫外线) ate more food.
To see if humans do the same, the team used data on about 3000 people who had filled in questionnaires as part of the Israeli government’s national health and nutrition survey. Between March and September, the men consumed about 17 per cent more calories per day than they did during the rest of the year, while the women’s food intake stayed about the same.
Human appetite is influenced by many complex systems, but a substance called ghrelin, a hormone produced in the body that stimulates appetite, seems to be the only hormone that directly stimulates eating. It was thought to be mainly produced by the stomach when empty. “It tells the brain to eat more,” says Caroline Gorvin at the University of Birmingham, UK.
Further investigation revealed that exposing male mice to UVB (紫外线 B 段波) radiation, which is present in sunlight, raised levels of ghrelin production by fat cells in their skin. This was blocked by the female sex hormone, which may explain why the effect wasn’t seen in the female mice or the women. Boosted ghrelin production was also seen in men’s skin samples that were exposed to UV light in the lab.
Skin hasn’t previously been thought to play a role in appetite, says Gorvin. The reason for the effect is unclear, but it may be an adaptive response to fuel greater physical activity in summer, says Levy.

Should Hand Feeding Dolphins Be Encouraged
Some tourist centers train Indo-Pacific bottlenose dolphins to approach beachside public sighting areas or boats by hand-feeding them small amounts of fish every day. Because hand-fed males aggressively attack each other over the food, putting themselves and nearby humans in danger, tourist centers focus their hand feeding only on female dolphins, says Valerie Senigaglia at Murdoch University in Perth, Australia
But recent studies have shown that only 38% of the calves (崽) of hand-fed wild dolphins survive to three years of age, which is much lower than the average 77% survival rate for wild calves in general. To better understand why, Senigaglia and her colleagues evaluated the social behavior of dolphins around the Bunbury coast in Western Australia. In particular, they observed the individual behavior and movement of 35 dolphins, including 13 that had been hand-fed using a small boat. They regularly followed each dolphin for periods lasting from 20 minutes to 3 hours for two years in a row for a total of 180 hours.
They found that hand-fed dolphins swam in relatively large groups, but more readily broke away from them to join different ones. In general, they created weak ties with other group members. “You can feel lonely in a room full of people and it’s the same thing for dolphins,” says Senigaglia. Free-swimming dolphins that are fed by hand become less socially involved with their peers. As a result, their calves may grow up lacking vital social skills-which could explain, at least in part, why they are twice as likely to die before reaching adulthood as wild calves generally.
No wonder animal right activists are calling on the practice of hand-feeding dolphins to be stopped.

Is Leather Good or Not
For thousands of years, humans have used leather to make everything from clothing to furniture to footwear. The skin of animals is a material that is strong, hard-wearing and flexible. These qualities make leather a popular material for many different products, but more people are becoming concerned about the potential harm caused by items they buy. Should we respect ancient traditions or is having real leather not as important as it used to be
The treatment of animals raised for their skins is a massive issue. According to the Food and Agriculture Organisation (FAO), more than 2.29 billion cows, pigs and goats are killed each year for their hides. This does not include the animal skin of fancier leather products, such as sheep, crocodiles, kangaroos and lizards.
There’s also an environmental problem. Producing leather is a very polluting process, because it requires treating the skins with chemicals. During the procedure, called tanning, chemicals change the fibres (纤维) inside the leather, making it tougher. A tanning facility uses more than 60,000 litres of water for every tonne of leather produced. It uses huge amounts of poisonous chemicals, including substances containing heavy metals such as chromium, which when washed out ends up in nearby soil and drinking water that people use.
However, the making of leather is not entirely negative. Selling animal skin is a key source of income for remote populations such as the Inuit people in Canada. Every day, cows, pigs and goats are killed for their meat to be sold in supermarkets. It’s respectful not to waste anything, and without leather their skins would have to be buried or burned.
Although there are alternatives to leather, some of these fabrics are only 85% to 90% biodegradable (可生物降解的). Vegan leather can be made from plastics which take years to biodegrade, so it’s actually worse for the planet.

Why Don’t We Use the Math We Learn in School
How much of the math you’ve learned in school is used in everyday life For the majority of people, the answer is surprisingly little. Clearly, some people learn math very well and apply it in everyday problem-solving settings. The question is why most people don’t, in spite of spending many years practicing it.
The first explanation blames the failure of education. One of the major barriers to using a skill in real life is automaticity. We tend to find the least-effort solution to our problem. If struggling through a math problem is hard for you, you’ll find a different way to solve it that doesn’t rely on math. The familiar model for teaching mathematics revolves around teachers telling students certain rules, applying those rules to examples and students then practicing problems similar to the examples seen in class. By teaching in this way, a lot of the work and deep thought that went into the creation of these mathematical rules is lost. In that sense, people were never taught math thoroughly enough to use it automatically in real life.
The second explanation is a little different. It argues that people may develop competence in math classes, but they struggle to translate real-life problems into a format where they can use their mathematics knowledge. This seems most apparent in the case of applying algebra (代数). Students struggle with algebra, but they particularly struggle with word problems. Yet, the equivalent real-life problems are typically much harder than word problems. From this perspective, what people struggle with is not doing math, but recognizing where and how to apply math to real problems.
Educational researchers now emphasize the importance of transfer and deep understanding. They believe we need to give students more training in noticing and converting everyday situations into the math problems they know how to solve. By using real-life math applications, students can make connections between math and everyday life.

Are Oceans Silent
Most sea creatures, from whales and dolphins to fish, sharks and shrimps, respond to sound, and many can produce it. They use it to hunt and to hide, find mates and food, send messages and give warnings, establish territories, warn off competitors, confuse their targets, deceive enemies, and sense changes in water and conditions. Marine animals click bones, grind teeth and belch gases (磨牙打嗝); use special organs to make various noises. Far from the ‘silent deep’, the oceans are so noisy.
Into this age-long confused noise, in the blink of an evolutionary eye, has entered a new thunder: the trembling sound of mighty engines as 46,220 large ships passed the world’s shipping courses. Scientists say that background noise in the ocean has increased roughly by 15 decibels (分贝) in the past 50 years. It may not sound like much in overall terms, but it is enough, according to many marine biologists, to mask the normal sounds of ocean life going about its business. At its most intense, some even say noise causes whales to become disoriented, dolphins to suffer from ‘the bends’, fish to go deaf, leave their breeding grounds or fail to form groups—enough to disorganize the basic biology of two thirds of the planet.
“Undersea noise pollution is like the death of a thousand cuts”, says Sylvia Earie, chief scientist of the U.S. National Oceanic and Atmospheric Administration. “Each sound in itself may not be a matter of critical concern, but taken all together, the noise from shipping, earthquake-related surveys, and military activity is creating a totally different environment than existed even 50 years ago. That high level of noise is bound to have a hard, sweeping impact on life in the sea.

Chatbots
What if instead of clicking on link after link on a company’s website, you could type a question and get an immediate, customized answer Some companies are working to make this a reality using chatbots. Chatbots are computer programs that can communicate with human beings by phone, on messaging apps or on websites.
There are two types of chatbots: open and closed. A closed chatbot follows a script, which may or may not involve using AI (artificial intelligence) to understand users’ messages. An open chatbot uses AI both to figure out what users want and to generate responses. Open chatbots are able to learn from their conversations and thus improve their ability to communicate over time. This means that open chatbots can respond to a wider range of inquiries, compared with closed municating with them feels more natural, but if they have not been correctly trained, users may have a bad experience with them.
One significant advantage of chatbots is that they are available all the time, even in the middle of the night. Plus, a single chatbot can cater to multiple users at once. This means that users can get immediate answers to their questions rather than waiting for a human representative. Chatbots have the potential to overcome several technological problems people face. These include difficulty in searching websites and trouble finding basic information and answers to simple questions.
However, in order for chatbots to work, humans are still indispensable (不可或缺的). Someone has to program the chatbots initially, train them, and maintain and improve the chatbot system. Further, even open chatbots may not have the answers to detailed questions, and many people simply prefer speaking to a human rather than a chatbot. Thus, chatbots are unlikely to completely replace human agents. Rather, they will help users resolve simple problems so that customer service representatives can focus on more difficult issues.

Graduates Turn to Teaching
China has witnessed a 66-fold increase in the number of applicants for teaching qualification tests over the past decade, and experts say the popularity has mainly been driven by more graduates chasing stable jobs. According to the latest figures from the Ministry of Education, the number of applicants for teaching exams each year has grown from 172,000 to 11.44 million in the past decade.
Experts said the sharp increase corresponds with the increase in teachers’ salaries and status within society, and it is expected to bring about an overall improvement in quality teaching. However, another big reason for the enthusiasm for teaching posts is that the challenging and complicated employment situation is driving graduates toward stable jobs such as working as teachers and government officials.
Chu Zhaohui, a senior researcher at the National Institute of Education Sciences, said the popularity of teaching posts is closely associated with people’s changing perception of the economic situation, job stability and security, which are major concerns for graduates.
In view of the coronavirus epidemic in recent years, many college graduates just want a stable job, so teaching suddenly becomes a very popular profession, and many students from well-known universities have joined the competition. Of course, everyone has their own ideas. Take Wang Lin for example. Wang Lin, who graduated from a famous university, said she had wanted to be a history teacher since middle school, inspired by her own history teacher. She added she had a good impression of her teachers from an early age and was grateful to those who had taught her. In fact, there are many such cases.
While passing the teaching qualification test is the first step to becoming a teacher in China, landing a post at schools in big cities can be very competitive.

Out of Sight, Out of Mind
Technology has made paying all sorts of bills incredibly easy. The real-time budget apps, which capture our spending and pay our bills automatically, should theoretically give us more control over our money. But why, in real life, do they do the opposite
It helps to think about how we used to pay. My parents describe a process that would involve three separate points of contact whenever they paid for something with a credit card: first, at the cash register, then when a bill came in the mail and finally when they wrote a check to cover it. While each of the checkpoints is technically still there, automation has given us a chance to skip the second and the third. For bills paid automatically through a banking app, even the first checkpoint can be gone. We know that it is happening in the background, but it’s so far out of view that it might as well not be there. How do we get that connection back, without giving up the convenience that technology has brought us
The good news is that though technology has taken away something, it can also give. Much of the battle is simply recognizing what we’ve lost. If we want to be smart about our money and have thorough control over it, we need to bridge that gap between what we spend on and how much we pay. We can start using personal-finance apps to do more than make our lives easier. These apps can send us notifications when each automatic payment is being made and categorize purchases, sending us instant spending reports. Admittedly, those tools require the user to sign up for these services and make conscious efforts to take full advantage of them. In this way, they are arguably better practice than balancing a checkbook on a Saturday morning.

8.One possible version:
Chatbots are communication computer programs. Closed chatbots follow fixed instructions while open chatbots can respond more flexibly using AI. Chatbots’ advantages include working round the clock and communicating with several people at the same time. However, chatbots won’t replace humans because chatbots are programmed by humans. Additionally, chatbots can’t answer detailed questions and many people just dislike them. (58 words)
【导语】这是一篇说明文。文章主要介绍了一种聊天机器人,包括它的类型和优势,以及人们对它的看法。
【详解】1.要点摘录
①Chatbots are computer programs that can communicate with human beings by phone, on messaging apps or on websites.
② A closed chatbot follows a script, which may or may not involve using AI (artificial intelligence) to understand users’ messages. An open chatbot uses AI both to figure out what users want and to generate responses. Open chatbots are able to learn from their conversations and thus improve their ability to communicate over time.
③One significant advantage of chatbots is that they are available all the time, even in the middle of the night. Plus, a single chatbot can cater to multiple users at once.
④However, in order for chatbots to work, humans are still indispensable (不可或缺的). Someone has to program the chatbots initially, train them, and maintain and improve the chatbot system.
⑤Further, even open chatbots may not have the answers to detailed questions, and many people simply prefer speaking to a human rather than a chatbot.
