Who could have imagined that a treadmill (跑步机) on wheels would one day become a thing? The Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill. It's actually cooler than it sounds.

    The Lopifit founder Bruin Bergmeester said it all started when he asked himself the question “How can I use a treadmill outdoors?” Then he spent the next few years figuring out a way to make it work He eventually came up with a functional design, added an electric engine, and the Lopifit was born. It's similar to an electric bicycle in that the motor only engages when the rider puts power in as well. Only while typical electric bikes are given pedal assist, the Lopifit senses when you walk on the treadmill and use the motor to turn a drive chain under the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery and use your foot to slide the treadmill backwards and then start the motor. Then get on and enjoy the ride! H you need speed, just walk on the treadmill, and if you want to coast, all you have to do is stay still and admire the view. To stop, you have two hand breaks. The right hand break stops the electric bicycle, while the left one stops the treadmill itself. It sounds and actually looks simple enough to use, but most of those who have tried it say that it takes some time to get used to it.

    The Lopifit first hit the streets in 2014 and, unsurprisingly, became an instant hit. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle became available this year, and the Lopifit is struggling to keep up with demand, despite the high price, $2,115.

Lantern Festival falls the fifteenth day of the first lunar month. This is the first full moon of the new year, representing unity and perfection. This festival also marks the (officially) end of the long holiday.

There are many legends (传说) related to the origins of Lantern Festival. According to one legend, once in ancient times, a celestial (天堂的)swan came into the human world where it (shoot)down by a hunter. The Jade Emperor, the (high)god in Heaven, was angry about this. He planned an attack on Earth on the   (fifteen) day of the first lunar month, with orders to destroy all people and animals. But the other celestial (begin) to disagree with him and risked his life (warn) the people on Earth. As result, before and after the fifteenth day of the first month, every family hung red lanterns outside their doors and set off firecrackers and fireworks(烟花爆竹), giving the impression their homes were already burning. By successfully tricking the Jade Emperor in this way, human beings were saved from(destruct).

It was the first time in a year and a half that I the night .

    With so much information available in books and online, it's easy  (learn) a few new facts each day. But how much of that do you  (actual) remember? your answer is not much, here is the good news. Scientists at RMIT University in Melbourne, Australia, recently designed a new typeface (字体)  was invented with read-it-and-forget-it people  mind. Very appropriately, it's called Sans Forgetica.

    The idea behind Sans Forgetica is simple. The typeface is a tiny bit  (difficulty) to read, which  (mean) your brain has to work twice as hard to understand what it says. Because of that deeper focus, you'll have a better memory for whatever you're reading. That's not just a theory, either. The typeface was created by a team of  (researcher) from RMIT University's School of Design and its Behavioural Business Lab. The group worked with a famous typographer Stephen Banham to test and improve  (they) product.

    The typeface uses principles of cognitive psychology to create an effect  (know) as desirable difficulty, the researchers note, which causes the brain to take part in deeper cognitive processing. The result is improved memory.

    How much money should I spend each month? This is asked by college students at the start of every term, and it's become a hot topic of discussion following a controversial online post. The post was about a college student who demanded 4,500 yuan for monthly living expenses from her mom, reported China Daily

In the post, this new college student explained that her school is in a top-tier city and that her expenses included skin-care products and new clothes. Her mother did not agree and "only" gave her 2,000 yuan.

    The post started a heated debate. Some people came to her defense. Girls invest a lot in skin-care products and new clothes while boys invest much in shoes, latest electronic devices and equipment for games.

However, someone thinks 4,500 yuan is too much. According to a 2019 report, students in 15 cities spent more than 1,500 yuan a month on average. Beijing topped the list at 2,400 yuan, and Shanghai followed close behind at 2,300 yuan. In some cities, a parent may only earn a monthly salary of 4,000 or 5,000 yuan. Nevertheless, some students insist on buying Dyson vacuum cleaners (吸尘器) for their dormitories instead of common brooms. Others demand Apple laptops to study at Starbucks, instead of going to the library.

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease — especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body's special needs. Both types have simply been called "well". In recent years, however, some health specialists have begun to apply the terms "well" and "wellness" only to those who are actively attempting to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body's condition. Most importantly, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be "well". In this new sense, if they make an effort to maintain the best possible health, they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life.

I'm sure everyone will this activity.
