【推荐1】For more than 50 years, seawater has flowed through the Hong Kong’s toilets. And in 2013, Hong Kong built a system that used seawater to cool part of the city. The system sends cold seawater to a factory with heat exchangers. The seawater takes in heat to cool pipes full of circulating (循环的) water. That cooled water then flows into buildings to cool rooms. The slightly warmed seawater is sent back to the ocean. Known as district cooling, this type of system tends to use far less energy than typical air conditioners.

How much water and energy had this strategy saved Hong Kong? And why weren’t other coastal cities doing this? A team at the Hong Kong University of Science and Technology set out for answers. They focused on Hong Kong and two other big coastal cities: Jeddah, Saudi Arabia, and Miami, Fla. The idea was to see what it might look like if all three adopted city-wide saltwater systems.

All three places would save lots of fresh water and energy, the researchers found. These savings came from the more efficient saltwater air conditioning. Though costly to build, saltwater-cooling systems could pay off in the long run for many cities.

The researchers figured out how emissions (排放) of greenhouse gases would drop if each city instead used seawater for cooling and flushing (冲刷). Next, they studied how much pollution would be created to build the new system. They compared these results to see how emissions of climate-warming gases would change for each city.

Hong Kong would see the biggest cut in greenhouse gases if the system were expanded to the whole city. It could drop by some 250,000 tons each year. Miami could see a drop of around 7,700 tons of carbon pollution per year. Saltwater cooling would cause more planet-warming gases in Jeddah than it would save. The reason: Jeddah’s unplanned urban expansion and all the pipes that would be needed to service it. The pollution coming from building such a large system would be higher than what the system would save.

Of the global herbal (药草的) medicine sales volume, the Chinese mainland accounts for only 2 percent and Japan has the lion’s share of the market, far ahead of other countries. More than 100 countries and regions around the world have set up TCM institutions, with the United States, Europe, Japan and South Korea spending millions of dollars in research and developing medicine. The UK-based pharmaceutical giant GlaxoSmithKline announced its first TCM medicine research and development program, which targets not just the Chinese market, but the global one as well.

“TCM is a well-built medical science based on thousands of years of clinical practices. It shows great promise treating complicated conditions that the single-target Western medicine has failed to handle,” says Zang Jingwu, senior vice-president and head of GlaxoSmithKline’s R&D in China. “Our focus is to transform TCM from an experience-based practice to evidence-based medicines through innovation,” he says.

Currently, a 10-person team in Shanghai is in charge of the program. However, TCM is different from Western medicine, so great innovation is required to combine the two sciences. In fact, many in Western medicine circles have recognized the importance of TCM, but the problem is how to prove and develop that. TCM is developed through practical experience and improvement of herbs but many people in the West don’t trust that. TCM, particularly herbal products, are largely available in the US and Europe, but questions like how to prove their effectiveness in the context of Western medicine and how to best use them remain unanswered.

Zhang Lingping, director of the international cooperation department of the Beijing University of Chinese Medicine, welcomed the emerging trend. “Their increasing interest shows Western medicine circles have begun to learn about the time-honored medical science, which originated in China,” she says.

【推荐2】The city of Lviv in Ukraine as I have seen in winter, greatly reminded me of several famous cities of Central and Eastern Europe that I have been to, such as Prague.     1     So you cannot make a single step without running into the next attraction.

The first thing that caught my eye was the architecture. I was astonished, though I am a beat-up traveler. The reason for my surprise is that Lviv’s houses breathe with history. While walking in the streets, you will repeatedly catch yourself imagining getting into the 17th century somehow.     2     I got one of my first bright impressions about Lviv almost immediately after my arrival, walking around the city center early in the morning, searching for a hostel to check into.

    3     They are the number of themed cafes and restaurants, and extremely polite and friendly people. As for the cafes, they can be safely considered a hallmark of the city; looking back, I can tell you that you can hardly find two cafes in Lviv that would be at least remotely similar to each other.

People in Lviv are friendly.     4     The people I was talking to knew English quite well-knowledgeable enough to explain to me where I could go and what to see. Even individuals who didn’t speak a word in English still tried to give me a hand, using gestures and laughter, which was funny both for me and for them.     5     So maybe this was the reason for the people’s uplifted mood.

The best time to visit Toronto is typically in the spring (April and May) or during the fall (September to early November). At these times, you’ll likely find fewer crowds, cheaper accommodations, and the best weather for sightseeing as it is neither too hot nor too cold.

The Toronto Transit Commission (TTC) makes it easy to get around the city via many buses, subway, and streetcars. Figuring out how to get where you want to go is easily done using the TTC’s convenient Trip Planner.

While you may choose to base yourself near many of the city’s main landmarks, it’s also worth taking some time to explore some great neighborhoods that each offer their own unique charms, including colorful Kensington Market, the Junction, Leslieville, and Little India.
