A first-of-its-kind elevated steel pedestrian walkway system     1     (run) through forested areas in China, Fuzhou Forest Walkway,     2     (common) known as “Fudao”, extends over 6.3 kilometers from end to end, covering about 19 kilometers along its winding path.     3     (design) as an urban connector, “Fudao” links two bodies of water, while providing public access to the hills outside of Fuzhou’s city center.

The project forms part of a larger redevelopment of the area, which also saw     4     (significance) improvements to the region’s facilities. An existing bus station has been transformed     5     a visitor center, while a fish pond has been repurposed as a bio-retention (生物滞留) lake.

The walkway consists of six basic deck components     6     can be ordered and linked together in various ways. The project is a system capable of crossing over the rolling mountains, while protecting the ecology of the site. The use of a porous grating (格栅) for decks     7     (allow) natural light to reach the ground plane, encouraging low-lying plants     8     (grow).

The walkway has a consistent 1:16 gradient (坡度), which enables barrier-free access along its entire length. This was an important     9     (consider) for public access, ensuring that it could     10     (enjoy) by people of all ages. Conveniences such as rest areas, viewing decks, observation towers, and teahouses have been included, adding variety and character to the site as an eco-tourism destination.

4 . Research has shown that mindful eating has positive impacts on people, so it’s beneficial to know how to eat more mindfully. Here are some techniques for eating at a healthy pace.

Remove all distractions while you eat.     1     Make sure your cell phone is face down and you’re not going to be responding to any messages that come through.

Take enough time to finish your meal. Even with all distractions removed, very often you still find yourself eating faster than you should.    2     It takes about that time for your body to get the signal to the brain that you are full.

    3     You might wonder how to spend 20 whole minutes eating a sandwich. One way to slowdown is to engage your senses and think through all the details about your meal. Ask yourself: What’s on my plate? How hungry am I today? Is it too salty? Notice the smell, the taste and whatever other senses that arise as you eat.

Limit the amount of the food you might munch on(大口吃) mindlessly. Put a small amount of snack food, like potato chips, in a separate bowl to help avoid mindless munching.    4     Putting aside some of the food can help you eat less at a healthier pace.

Actually chew. If you’re wolfing down(狼吞虎咽) your food you’re probably not chewing it. And chewing is an important part of digestion.     5     Look at each bite before putting it into your mouth, acknowledge what you’re eating and chew, chew, chew.

5 . Building artificial intelligences that sleep and dream can lead to more dependable models, according to researchers who aim to mimic (模仿) the behavior of the human brain.

Concetto Spampinato and his research members at the University of Catania, Italy, were looking for ways to avoid a phenomenon known as “disastrous forgetting”, where an AI model trained to do a new task loses the ability to carry out jobs it previously excelled at. For instance, a model trained to identify animals could learn to spot different fish species, but then might lose its ability to recognize birds. They developed a method of training AI called Wake-Sleep Consolidated Learning (WSCL), which mimics the way that our brains reorganize short-term memories of daily learning when we are asleep.

Besides the usual training for the “awake” phase, models using WSCL are programmed to have periods of “sleep”, where they analyze awake data from earlier lessons. This is similar to human spotting connections and patterns while sleeping.

WSCL also has a period of “dreaming”, which involves novel data made from combining previous concepts. This helps to integrate previous paths of digital “neurons (神经元)”, freeing up space for future concepts. It also prepares unused neurons with patterns that will help them pick up new lessons more easily.

The researchers tested three AI models using a traditional training method, followed by WSCL training. Then they compared performances for image identification. The sleep-trained models were 2 to 12 percent more likely to correctly identify the contents of an image. They also measured an increase in how much old knowledge a model uses to learn a new task.

Despite the results, Andrew Rogoyski at the University of Surrey, UK, says using the human brain as a blueprint isn’t necessarily the best way to boost AI performance. Instead, he suggests mimicking dolphins, which can “sleep” with one part of the brain while another part remains active. After all, an AI that requires hours of sleep isn’t ideal for commercial applications.

10 . “Anxiety.” The very word invites discomfort. Its effects—shortness of breath, pounding heart, muscle tension—are outright upsetting. But, as a clinician, I find that we tend to miss out on many valuable opportunities presented by this human emotion. In and of itself, anxiety is not deadly, nor is it a disease. Quite the contrary: it is an indicator of brain and sensory health. Once we accept that it is a normal, though uncomfortable, part of life, we can use it to help us.

We all know working out at the gym is hard. By nature, a “good workout” is uncomfortable, since it involves pushing our physical strength past what we can easily do. The sweet spot of exercise is always a somewhat challenging experience. Similarly, if you want to be emotionally stronger, you need to face some tension. For example, one effective treatment for fear is exposure therapy (疗法), which involves gradually encountering things that make one anxious, reducing fear over time.

Humans are social creatures. When my patients learn to open up to their partners about their anxieties, they almost always report a greater sense of emotional closeness. Also, as international relationship expert Sue Johnson teaches, when we express our need for connection during challenging moments (e.g., “I’m having a hard time right now and could really use your support”), it creates greater connection and turns our anxiety into love.

From time to time, we find ourselves at the end of our rope. Our responsibilities pile up, our resources break down, and we feel uncomfortably anxious—what we’re experiencing is called stress. Simply put, the demands placed upon us outweigh our available resources, just like a set of scales (天平) going out of balance. Focusing on work and pretending everything is OK only leads to disastrous results. Medical treatment for stress may function for a while, but it tends to make things worse in the long run. The only solution to deal with stress is to do the mathematics to balance the scales.
