Let's say you want to hit the gym more regularly this year. How do you make that happen? Consider putting the habit loop to use.
Here's how it works:
A habit is a 3-step process. First, there's a cue, something that tells your brain to operate automatically. Then there's a routine. And finally, a reward, which helps your brain learn to desire the behavior. It's what you can use to create-or break-habits of your own.
Here's how to apply it:
Choose a cue, like leaving your running shoes by the door, then pick a reward-say, a piece of chocolate when you get home from the gym. That way, the cue and the reward become interconnected. Finally, when you see the shoes, your brain will start longing for the reward, which will make it easier to work out day after day. The best part? In a couple of weeks, you won't need the chocolate at all. Your brain will come to see the workout itself as the reward. Which is the whole point, right?
1. Which of the following best fits in the box with a “?” in THE HABIT LOOP?
| A．Pick a new cue. | B．Form a new habit. |
| C．Choose a new reward. | D．Design a new resolution. |
| A．changing the routine | B．trying it for a week |
| C．adjusting your goal | D．writing it down |
| A．To test out different kinds of cues. |
| B．To do something as a habit even without rewards. |
| C．To work out the best New Year's resolution. |
| D．To motivate yourself with satisfactory rewards. |
| A．The Harry Potter poster. |

Know how to stop a nosebleed.
People commonly catch the bridge of their nose and lean back to stop a nosebleed, but this is quite wrong. The right way to stop nosebleeds is to lower your head forward, so the blood doesn't drip back and into your windpipe.
The best way is to put a cotton ball inside the nose and press the areas of the nose where air comes in and out when you breathe.
Know when to call the doctor.
If you've tried how to stop a nosebleed two or three times without luck, it's time to call your doctor. This is especially true if the blood is bright red and flowing quickly.
You don't have to worry about how to stop a nosebleed if you avoid them in the first place. The ideal way to prevent nosebleeds is by keeping your nose moist. Blood vessels that come too close to the surface and crack cause the bleeding which usually happens when the nose is dry. Salt water spray is a great convenient option. Humidifiers （加湿器）are another option, too.
| A．Know how to prevent nosebleeds. |
| B．Know what to do to cure nosebleeds. |

【推荐1】HANGZHOU-Chinese internet giant Alibaba on Tuesday opened a hotel loaded with artificial intelligence (Al) and robots, automating a series of procedures like check-in, lights control and room service.
FlyZoo Hotel, opened in Hangzhou, capital of East China's Zhejiang province, where Alibaba is headquartered, is known as the company's first "future hotel”. Customers can check into the hotel by simply scanning their faces. The facial recognition system installed in the hotel also enables customers to use their faces as key cards to open doors and access another hotel service. Users can also control the lights, televisions and curtains in the room via Alibaba's voice-activated digital assistant, while robots are deployed to serve dishes, cocktails and cofiee. Hotel bookings and check-out can also be done with a few clicks on mobile through an app. nThe Al-based solution can help customers save time and relieve hotel employees from repetitive work，" said Wang Qun, CEO of FlyZoo Hotel. The hotel is the latest example of Chinese tech companies1 attempt into traditional industries such as the hotel industry.
E-commerce giant JD. com announced in October its strategy to put smart home and electronic devices sold on its platform into hotels, in an effort to improve online sales.
In July, Baidu teamed up with Intercontinental Hotels Group in Beijing to allow guests to use its voice-controlled assistant to adjust room temperature and order room service at ease.
Before that, social media giant Tencent introduced QQfamily, a similar tech solution for hotel operators, in the southern city of Zhuhai last year.
"We want to install a 'smart brain' for hotels, " said Wang, "In the future, we will continue to make hotels smarter and more automated, as well as create more personalized experiences for consumers."

【推荐2】Stanford University has begun an investigation following claims that some of its staff knew long ago of Chinese scientist He Jiankui’s plans to create the world’s first gene-edited babies.
A university official said a review was under way of interactions some faculty members had with He. who was educated at Stanford. Several professors including He’s former research adviser have said that they knew or strongly suspected that He wanted to try gene editing on embryos (胚胎).
The Chinese genetic scientist posted a video on You Tube in November 2018. He claimed in the video that he had used a gene-editing tool Crispr-Cas9 to modify (修改) a particular gene in two embryos before they were placed in their mother’s womb (子宫). He, who works in a lab in the southern Chinese city of Shenzhen, said the twin girls, known as Lulu and Nana, were born using an egg that was modified. He focused on HIV infection prevention because the father is HIV positive. “Now the father has a reason to live, a reason to work, he has a purpose,” He said.
Editing the genes of embryos, which can change other genes, is banned in many countries because DNA changes are passed to future generations and could have unforeseen effects on the entire gene pool.
China’s national health commission ordered officials to “seriously investigate” He’s claims. Shenzhen’s health and family planning commission said it was investigating the review process around He’ s work.
Research institutions connected to He have distanced themselves from him. “This research work was carried out by Professor He Jiankui outside of the school,” said the Southern University of Science and Technology in Shenzhen. It called his research a “serious violation of academic ethics (道德)”.

【推荐3】Zero-emission large passenger aircraft powered by hydrogen will be technically available in five years, according to Airbus, but they will not enter service for at least a decade as the price of the fuel needs to come down.
The prediction comes from Glenn Llewellyn, vice-president of zero-emission technology at the pan-European plane-maker. He said that while Airbus planned to demonstrate hydrogen-powered aircraft in 2025, over the next 10 years, hydrogen won't be more economic than the fossil fuel equivalent. “To make real emissions free hydrogen-powered planes, which give out only water and heat, their fuel needs to come from hydrogen produced via renewable sources such as wind and solar,” he added. Another barrier is building up the ecosystem that hydrogen aircraft will need”.
However, Mr Llewellyn predicted that there was enough interest in the sector to make this happen. In an interview, Mr Llewellyn said, “We already see massive increases in the amount of renewable energy being produced across the world. Wind energy production has multiplied by two over the last five years and solar energy production has multiplied by four.” He added, “There are a number of independent institutes that have mapped out how hydrogen costs can come down over the next decades. We see a 30% reduction in renewable hydrogen costs in 2030 compared to where it is today, and a 50% reduction in renewable hydrogen costs by 2050. They are exactly the kind of cost figures that are interesting for us, because it makes zeroemission aircraft commercially viable （可行的）in the 2030s.”
Last month UK-based Zero A via conducted the world’s first flight of a commercial - grade aircraft powered by hydrogen. A few days before, Airbus announced a series of design proposals for hydrogen-driven aircraft, including a “blended wing” concept that provides greater storage capacity. This design could be key to hydrogen-powered aircraft as the fuel is less energy dense （密度大）than conventional fuel and so requires more space to match performance of existing airplanes.
