You have probably heard the saying,"When life gives you lemons,make lemonade."Since lemons are considered bitter and lemonade is considered sweet,the saying tells you to make the best out of a bad situation.

    Unfortunately,when something bad happens,it's not uncommon for most people to talk about it to anyone who'll listen,and complain about life,"Why me?"That's like getting a bag of lemons,putting them down,and thinking, "Lemons taste bad!I'd rather have chocolate!"If you don't make anything with the lemons,they will go bad.But what if you did something with them?What if you made lemonade?Isn't it possible to do something similar with a bad situation?

    Here's an example.Let's say you're about to go to the movies,but you discover you have a flat tire（瘪胎）.You consider this a terrible thing. After all,you are really looking forward to spending some time with Ryan Gosling and Emma Stone.Now you're all stressed out,hating the tire,the car,and your life.But what if you called AAA,got your tire fixed or got caught up on things that you'd been meaning to do?What if you did some reading,or had coffee with a friend instead?A negative experience can be turned into something positive.Almost anything can work itself out into something better.You can't change what has happened,right?So make the best of it.I'm not saying it will be easy. The easy thing to do is complain about your bad situation and not consider what it could be turned into.

    Next time when some unfortunate things happen,stop and think,"How can I turn this around?How can I make it a positive experience?You needn't fear difficulties.As long as you keep on changing it,you will see the benefits（好处）at last.

    When Wu Jia, then aged 23, returned from Canada to work for her father's Hangzhou-based Zoland Animation (动画) in 2007, she found Chinese animation productions were just-so-so. Back then, Chinese animation shown at overseas events, received a poor response.

    But things soon changed following a boom in China's movie and television industries. By 2011, China developed into one of the world's largest animation producers, with animation and cartoon products reaching a record of 260,000 minutes.

    However, that figure has witnessed a fall in recent years. The latest statistics show that China made only 244 animated productions totaling 83,600 minutes in 2017. But Wu says: “Chinese animators are changing from quantity to quality and Chinese animators are now producing more quality works” at the 14th China International Cartoon & Animation Festival.

    Wu, now the chairman of Zoland Animation, is among those who are part of China's rapidly growing animation industry. She says the company has so far displayed more than 8,000 hours of animated content to 93 countries and regions, including the United States, United Kingdom, France, South Korea and Russia.

    Magic Eye, one of Zoland's most popular animated works, which was sold to just Singapore in 2006, is now reaching the screens of nearly 80 countries and regions worldwide. The 500-episode animated series about an alien boy's adventures on Earth also has a sequel (续集) series Magic Eye is Back, which has 104 episodes. Thanks to Magic Eye's popularity, the sequel quickly arouses interest in overseas markets and is being displayed in 38 countries and regions.

    Speaking about how to succeed abroad, Wu says: “First, the works should be good. And, you need an experienced team who knows international markets.”

    Bargain hunters spent a record of 168.2 billion yuan ($25.3 billion; 21.7 billion euros; ￡19.3 billion) during the 2017 Singles Day on Nov. 11, the world's largest daylong discount festival, as e-commerce giant Alibaba Group took online shopping to offline stores and beyond(超越) the nation's borders(边界).

    Spending climbed by 39.3 percent during this year's sale, as consumers from 225 countries and regions scooped up goods from 140,000 brands (品牌)that offered promotions during the annual event.

    Alibaba surpassed last year's 120.7 billion yuan total shortly after 1 pm, as overseas shoppers joined in the afternoon, seeking good deals from China. Expanding at a faster-than-expected pace, the total eclipsed (使黯然失色) the combined sales of Black Friday and Cyber Monday in the United States last year. Nine out of ten people used mobile wallet apps for payment, says Alibaba, with its Alipay app having handled 1.48 billion transactions (转账) in 24 hours and processed them at a peak rate of 256,000 transactions per second.

    Meanwhile, some offline shops also joined in, turning into smart stores that allowed shoppers to track product availability at other locations and get timely delivery to their doorsteps while paying with their phone. "Using big data analytics powered by Chinese tech firms can help us locate customers in a precise manner, something we wouldn't have achieved using old-school retailing," says Gary Chu, e-commerce general manager.

    The Nov. 11 shopping event represents a China-branded business model that can also be spread to other countries, creating opportunities for businesses worldwide. As Singles Day grows, shoppers have used the opportunity to try out new items rather than simply bagging a bargain, says Tommy Hong, vice-president of Nielsen China.

    "That changing attitudes (toward Singles Day) is also consistent with China's shifting focus from quantity(数量) to quality growth," Gary Chu says.

    Black Friday is the day after Thanksgiving Day and the Friday before Cyber Monday in the United States. It is not a federal holiday, but is a public holiday in some states. Many people take a day of their annual leave on the day after Thanksgiving Day. Some people use this to make trips to see family members or friends who live in other areas or to go on vacation. Others use it to start shopping for the Christmas season. Many organizations also close for the Thanksgiving weekend.

    Shopping for Christmas presents is also popular on Black Friday. Many stores have special offers and lower their prices on some goods, such as toys. Public transit systems may run on their normal schedule or may have changes. Some stores extend their opening hours on Black Friday. There can also be congestion on roads to popular shopping destinations.

    Black Friday is one of the busiest shopping days in the USA. There are two popular theories as to why the day after Thanksgiving Day is called Black Friday. One theory is that the wheels of vehicles in heavy traffic on the day after Thanksgiving Day left many black markings on the road surface, leading to the term Black Friday. The other theory is that the term Black Friday comes from an old way of recording business accounts. Losses were recorded in red ink and profits in black ink. Many businesses, particularly small businesses, started making profits prior to Christmas. Many hoped to start showing a profit, marked in black ink, on the day after Thanksgiving Day.

Most of Bangladesh is at or below sea level. Rising seawater linked to climate change has severely affected the country. High water from storms in coastal areas also adds salt to soil. The land is becoming salty. Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

To find a way out，farmers in the country are learning to grow vegetables in so-called "vertical gardens". The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain (排水).

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12—$13 to build.
