When night falls, the hustle and bustle of the southern Chinese city of Guangzhou turns to the banks of the Pearl River in Liwan district. Hundreds of people and cars  (decorate) with colorful lights and eye-catching shop signs swarm (挤满) a local car boot sale bazaar (集市).

Liang Jinsheng, a local youth, sells lemon tea at the bazaar,  was opened to the public on July 15 last year. The almost one-square-meter car trunk is his space for tea making.

"I used (work) in the catering industry. I saw on the Internet many people doing business at car boot sale bazaars. So I decided to give it try, as doing business is low-cost and low-risk," Liang says.

"Although my ‘shop' is small, I have obtained the necessary business licenses will stick with hygienic (卫生的) standards to ensure food (safe)," Liang adds.

While  (make) the lemon tea, Liang also livestreams on short-video platforms to drive traffic.

"Recently, a lot of residents (come) to my tea booth after watching my livestream. I make around 1,000 yuan ($148) at the bazaar every night," he says.

most cases, Guangzhou will support these new types of business activities, says the city's commerce department, noting that many commercial plazas (露天广场) have offered  (much) space for car boot sales and introduced night-themed activities to stimulate consumption.

DeJuan Strickland now is a middle school student. He remembers what it was like to be 1 as a fourth grader at McCurdy Elementary. Though happening only once, that made Strickland determined to 2 no one at his former school would feel that way.

Strickland helped3 his former elementary school's unpaid student lunch debts through his GoFundMe fundraiser with the aim of raising $200. The result4 that, with $400 raised for McCurdy Elementary. "Some school workers told me several kids once able to have lunch very5 are stuffed every day now. It motivates me to go further because I'm able to see the6 ." says Strickland.

From there, Strickland7 the initiative to remove lunch debts in all schools of the Hazelwood School District. The campaign has8 over $4,000, $2,500 of which Strickland plans to give to the Hazelwood School District. He also searches for another district for the9 of the funds. Strickland recalled being10 when he learned the debts of a nearby district were over $50,000. "I'd11 the problem was not common. This really opened my eyes to the fact that there was no12 of food. "

Strickland owed his13 spirit to his mother. Her practice of creating "blessing bags" for those in need14 his sympathetic outlook. Strickland also works on his books on Tech Boy. The teen says his future plans include becoming a computer programmer, and combining his love for15 with giving back to the community.

Cultural intelligence, or cultural quotient (CQ) is the ability to manage cultural diversity.  It also involves understanding and appreciating cultural differences and being able to adapt to those differences.

 For one thing, it can help you avoid misunderstandings and communication breakdowns with people from other cultures. For another, it enables you to build strong relationships with them. Want to improve your CQ? Try the following tips.

If you're unfamiliar with the culture, chances are you're not going to adapt well to it. So the first practical aspect of CQ you need to improve is your CQ drive. This drive is the first step towards higher CQ that may help you be open to new possibilities. All you have to do is explore the new situation you find yourself in.

After you've motivated yourself to get a bit more familiar with the culture, it's time to go one step further. Of course, this doesn't mean you need to become an expert in the said culture. Simply, you should try to get to know the ways in which that culture forms and influences its people's values and behavior.

Lastly, you need to use what you have learned and come up with a strategy that will help you improve your CQ. You can expose yourself to various media. This is a useful and easily accessible way to learn about how culture affects behavior. Again, it helps if you learn the language of the culture. This may open a whole new world for you. 

A. You should broaden your CQ knowledge.

B. There are many benefits of having high CQ.

C. To be culturally intelligent is no easy matter.

D. This means your motivation to learn about a different culture.

E. Seek out opportunities to interact with people from other cultures.

F. This ability is not limited to your cultural sensitivity and awareness.

G. It can help you better understand people from other cultures as well.

As the planet gets hotter, the need for cool living environments is becoming more urgent. But air conditioning is not always recommended for use since units produce massive greenhouse gases and use lots of energy. Now, researchers have found in a new study an inexpensive, sustainable choice to replace mechanical cooling with refrigerants (制冷剂) in hot and dry climates, and a way to mitigate the dangers of heat waves during electricity blackouts.

The researchers set out to answer how to achieve a new benchmark (基准) for passive cooling inside naturally conditioned buildings in hot climates such as Southern California. They examined the use of roof materials that radiate (辐射) heat into the cold universe, even under direct sunlight, and how to connect them with temperature-driven air exchanges (that is, air can enter buildings and circulate freely). These cool radiator materials and coatings are often used to stop roofs overheating. Researchers have also used them to improve heat rejection from coolers. But there is untapped potential for mixing them with architectural design more fully, so they can not only reject indoor heat in a passive way, but also drive regular and healthy air changes.

"We found we could keep air temperatures several degrees below the ordinary temperature and several degrees more below the reference ‘gold standard' for passive cooling," said Remy Fortin, lead author and PhD candidate at the Peter Guo-hua Fu School of Architecture. "We did this without abandoning a healthy airing." This was never a piece of cake, considering air exchanges are a source of heat when the aim is to keep a room cooler than the outside.

The researchers hope the findings will be used to positively impact communities suffering from dangerous climate heating and heat waves. "We hope that materials scientists, architects, and engineers will be interested in these results, and that our work will inspire more thorough thinking about how to connect breakthroughs in radiative cooling materials with simple but effective architectural solutions," said Salmaan Craig, main investigator for the project and assistant professor at the Peter Guo-hua Fu School of Architecture.

Do you find yourself checking social media sites as soon as you wake up? Do you answer e-mails on your phone while surfing the Web? Actually, we've lived a life in which we're all connected, all the time. Whether or not this is a good thing is the subject of Hamlet's BlackBerry, a non-fiction book by William Powers based on an essay he penned.

Early in the work, Powers questions the way we use devices, but certainly he doesn't criticize it. He does, however, recognize the downside of constantly being overstimulated—or what he calls the "problem of connectedness". Among the things disturbed by the problem, Powers says, are the ways in which people are connected and deal with each other. "Constantly switching among people on social media platforms, texts and all the new ways of connecting all day, we never have a sustained connection." His intention of writing Hamlet's BlackBerry is to help teach people how to connect more wisely. Powers looked to the past, where he found several precedents(先例)for both the current information age and the anxiety that has come with it.

One major figure Powers examines actually developed his own strategies for dealing with overstimulation. In William Shakespeare's Hamlet, Hamlet is informed his father is murdered by his uncle and too shocked by the news to think calmly, so he pulls out his "tables" from the pocket, an object Powers describes as a so rt of original electronic planner. In the Elizabethan age, tables were a kind of new device designed to help people bring order to their lives despite massive news. You could write notes during the day and wipe(擦掉) them away at night.

But how do we deal with the same problem? Powers has one suggestion that's child's play: just disconnect. His family, for example, takes an "Internet Rest Day" every weekend. "We don't have smart phones. Therefore we can't check our inboxes and do Web surfing that day. We really enter another zone and it's wonderful. Even when we're connected to the Internet again, we feel benefits of having been disconnected days before," he says. "It's just about that simple word—balance."

Hiking is tricky when you're carrying a threatened species. Ally Whitbread carefully walked through the wilds while carrying a cooler full of small, rare snails (蜗牛)— the Chittenango ovate amber snails.

"I feel like I've got 500 babies to take care of — just like a very crazy mother hen," she said. Whitbread is part of a team transporting a lab-grown population to a new, remote home. The snails are facing extinction — only dozens are estimated to remain at one waterfall in upstate New York. "Such a recovery process can take years to decades. There are several things remaining to be unlocked during the process — what the action is going to bring, what role that species might play, and whether they might live well. We are just racing to better understand our planet's biodiversity before the species die out."

It took the scientists years to raise this population in the lab. The hike to a hidden waterfall is a chance to examine what makes them grow well in the wild, or what doesn't. The snails don't have any known unique features critical to humans, and it's been a long journey just to attempt to save them. These efforts could figure out their hidden benefits.

Specialist Cody Gilbertson said the drive to save them can go deeper, not just the love for science. The creatures are no bigger than a fingertip and look up at their caregivers. "You know their big eyes are staring at you, like — there's no way that you're not going to kind of fall in love," Gilbertson said.

Dropping them off at their new waterfall home wasn't even the end — it'll be another 5 years before the team knows whether the snails can survive there They'll go for a hike twice a month to track their progress.

I hadn't got exercise lately and felt a bit dizzy. I was a little1 . One of my friends invited me to show up to see a2 that they said would help me feel better. Little did I know that I was about to see something I would never forget.

They introduced a young3 , Mr Patrick Henry Hughes. He was4 onto the stage in his wheelchair and began to play the piano. His fingers5 across the keys as he made beautiful music. He then began to sing as he played, and it was even more beautiful. For some reason,6 , I knew that I was seeing something special. Ten minutes later, someone came on the stage and7 a video of Patrick Henry Hughes.

Patrick was born with no eyes and a tightening of the joints which left him8 for life. Before his first birthday, he9 the piano. On his second birthday, he asked to play it. His father was10 . "We might not play baseball, but we can play music together. "

Today, Patrick is a11 at university. His father attends classes with him and he has made nearly all "A" s. He is also a trumpet player of a band. He and his father do it together — they12 all the band practices and the half-time performance in front of thousands of people.

But even more than his13 musical talent, it was Patrick's attitude to gratitude that touched me. I will never forget that night, that smile, that music, but most importantly, that14 attitude to gratitude. Gratitude can change your attitude,15 your life forever.

When talking about classical music, what can you think of? Is it a big orchestra with an old guy in a black suit waves a stick in front? You are(part) right. But there is a lot more about it. Classical music can be as simple as just one singer singing a song. It can also mean orchestra with hundreds of musicians. Classical music can express an idea, explore a theme or convey emotions. It has its roots in the traditions of(Europe) art and concert music with a history of more than 1,000 years. Classical music is usually(serious) than other types of music. Listeners are supposed(stay) quiet and still.

Nowadays, more and more students are crazy about classical music(composer), such as Mozart, Chopin and Beethoven. They think their music can make them calm down, sleep well become smarter. They can perform better in tests as well. Besides, according to(they) musical preference, it is possible to tell the types of their personality. Professionals like teachers can use the personality information to determine whether they have a particular talent for music, which they never(know) before.
