3 . Bloomberg reported on the status of Tokyo Bay, the open water swimming venue for triathletes (铁人三项运动员). Bloomberg’s report actually sums itself up quite nicely in just two words: “It stinks.”

The question of water quality first came up in 2019. During a water test prior to a paratriathlon race, E.coli was detected in more than double the amount allowed for competition by the International Triathlon Union. A local newspaper quoted one athlete as saying the bay “smelled like a toilet”.

Where the problems lie in this specific case is that there have been concerns over the pollution in Tokyo Bay for a very long time. This is due to the Tokyo metropolis having a mixed sewage (污水) system. In a mixed sewage system, drainage (排水系统) for rainwater and sewage are combined, not separate.

According to Bloomberg’s report, during times of flooding, untreated sewage system gets flushed directly into the bay in an effort to avoid flood damage. So, what happens to the untreated waste water that gets pumped directly into the bay? For the most part, it simply stays in the bay. According to research by Koibuchi, due to the size and depth of the bay, approximately 60 percent of the water in the bay is from the rivers and Tokyo’s drainpipes.

In response to that water test, Tokyo put forward new efforts to clean up the pollution in the bay. These steps include dumping massive amounts of sand into the bay, putting in polyester screens to protect against E.coli, and installing new storage tanks to hold flood runoff, so it can be treated before being released into the bay. Despite these measures, the bay has been emitting an unpleasant smell for a few weeks, according to Bloomberg’s report.

In Northwest China's Gansu Province     1     (lie) Zhangye National Geopark, which is blessed with a spectacular Danxia (red cloud) landform area     2     (cover) about 19 square miles. The Danxia landforms are     3     masterpiece of nature. The colorful mountain ridges are just like an overturned palette from heaven. Bands of fiery red, creamy orange, rich green and bright yellow streak across the mountain, forming     4     is known as the most beautiful rainbow mountain.

The incredible landscapes were created by sandstone and minerals piling on top of one another over the years due to tectonic plate movements. Wind, rain, and tine then carved the rock formations and rolling hills into     5     (vary) extraordinary shapes, including towers, pillars and valleys.

    6     (declare) a UNESCO World Heritage site in 2010 and a national geopark in 2011, the landform has become a top tourist     7     (attract). The park features a series of boardwalks that allow visitors to walk around the colorful sandstone landscapes. There are viewing platforms     8    (special) designed, enabling tourists to get close to the hills and feast their eyes     9     the magnificent sights without damaging the fragile ecosystem.

8 . India has the world's worst air pollution. Home to 21 of the world's 30 most polluted cities, its poisonous air kills more than one million people each year.

Being the world's second largest brick producer, India's brick kilns (砖窋) account for of black carbon emissions globally. Architect Tejas Sidnal was astonished to discover the construction industry's role in the pollution crisis. "That was a crazy eye opener," he says. "As architects, we are responsible for so much air pollution."

Determined to make construction more sustainable and tackle India's air pollution, Sidnal launched Carbon Craft Design in 2019. The startup takes black carbon extracted from polluted air and upcycles it to make stylish, handcrafted building tiles (瓷砖).

To create the carbon tiles, Carbon Craft Design, together with Graviky Labs, uses a filter device to capture carbon soot (碳黑) from tail gas and fossil fuel generators, removes pollutants such as heavy metals and dust from the soot, and gives the purified carbon to Carbon Craft Design in powder form. The company then mixes the captured carbon with cement and marble waste from quarries to produce monochromatic tiles. The company aims to ensure each tile contains at least waste material. It sells the tiles to architects and retailers (零售商) for per square meter-a high price compared to regular tiles.

As the company expands production, Sidnal hopes to lower prices and produce a cheaper range of carbon tiles. "We want to hit the affordable sector," he says. "Sustainability is not only for the elite (精英)."

Since launching its first tiles a year ago, Carbon Craft Design's customers have included global fashion brands and architecture firms in India. In November 2020, an Adidas store in Mumbai covered the walls and the floor with its carbon tiles. Inquiries from in and out of India came flooding in.

Architect Manan Gala describes the carbon tile as a "winner", which, apart from being sustainable, has better strength than conventional cement tiles due to the carbon content, and the raw and rustic feel adds to the overall charm.

Birds are highly intelligent creatures, with complex and specialized forms of communication. Each species has     1     unique way of using body language and vocalizations（发声）to communicate. However, there are some things     2     birds do in general that you can understand. If you pay attention to your     3     （bird）regular mannerisms, you will be able to identify when they have changed. Also, you need to look at their movements or behaviors in context     4     （understand）them. If you can do this, you     5     （be）closer to understanding what your feathered friend is trying to communicate to you.

Birds are     6     （typical）very clean creatures and they spend a lot of time cleaning, preening and grooming their feathers. This is natural self-care behavior that is important for birds to do. Bathing is an important part of feather maintenance for birds. If your bird stops     7     （bathe）itself, that is a sign that it is no longer taking care of     8     （it）. This could signal depression, body pain, or lack of mobility. A bird that is singing or whistling a lot is likely very happy. A bird that is     9     （satisfy）is likely to chatter or talk a lot. In fact, if you spend time     10     them, they are likely to increase this chatter when you come around.

10 . Some people can't wait for the lovely colors, cooler weather, and cozy sweaters of autumn. In fact, fall is Americans' favorite time, but for a minority of others, the transition from summer creates worry, fear and worse. According to Carrie Landin, a psychologist from the University of Colorado Health Integrative Medicine Center, a significant number of people actually experience autumn anxiety.

For some people, stress is triggered (触发) by environmental factors: Decreases in daylight cause chemical changes in the brain. "Less daylight leads to lower levels of chemicals like serotonin and dopamine that control our emotions," says Kimberly Asner-self, associate professor at Touro Colleges` School of Health Sciences. "As these chemicals drop, the body responds by increasing levels of cortisol. the hormone released in situations where we face threat." The result can be an increased anxiety, difficulty sleeping and depression.

But it's not just increasing darkness that can trigger these symptoms. For people who feel this way every year, some of the reaction is mental. "When we know there's the potential for stress ahead we tend to anticipate the problems, feeling anxious before they even happen," Landin says.

The fall features more than its fair share of impending (迫在眉睫) events: back to school at the beginning of the season and family get-togethers toward the end. Mayra Mendez, a psychologist from Providence Saint Johns Health Center, suggests identifying your personal triggers and making a plan to manage them before they feel overwhelming. For instance, if you're concerned about family issues and holiday parties, decide in advance that it's perfectly OK to say no to some of them. If fall's stricter work and school schedules make you anxious, plan regular breaks and vacations to look forward to.

Finally, you should also find ways to embrace the present moment. Remember: while autumn may throw you a few tricks, there are plenty of treats to be found too.
