1 . Money Matters

Parents should help their children understand money.     1    . So you may start talking about money when your child shows an interest in buying things, candy or toys, for example.

● The basic function of money

Begin explaining the basic function of money by showing how people trade money for goods or services. It is important to show your child how money is traded for the things he wants to have.If he wants to have a toy, give him the money and let him hand the money to the cashier(收银员).    2    . When your child grows a bit older and understands the basic function of money, you can start explaining more complex ways of using money.

● Money lessons

Approach money lessons with openness and honesty.     3    . If you must say no to a child’s request to spend money, explain, “You have enough toy trucks for now.” Or, if the request is for many different things, say, “You have to make a choice between this toy and that toy.”

●     4    

Begin at the grocery store. Pick out two similar brands of a product—a kind of name-brand butter and a generic (无商标消费品),for example. You can show your child how to make choices between different brands of a product so that you can save money.     5    . If he chooses the cheaper brand, allow him to make another purchase with the money saved. Later, you may explain how the more expensive choice leaves less money for other purchases.

4 . Demand for the Chinese tech company's devices （设备） is red hot even though the country's overall market for smartphones is getting smaller. Huawei's China sales rocketed more than 20% in the final quarter of 2019，and experts say that partly due to the US government's global campaign against the company.

“The latest tension between the US and China raised the patriotism （爱国主义） in Chinese consumers”, said Jusy Hong, an analyst at research firm IHS Markit.

He pointed out that some Chinese companies encouraged employees to buy Huawei phones late last year. The moves were a gesture of support after the firms chief financial officer was arrested in Canada in early December at the request of the United States.

Huawei sold 30 million phones in China in the last three months of 2018, nearly three times as many as Apple （AAPL）, according to data published this week by research firms Canalys and IDC. Apples sales plunged almost 20%.

Huaweis success in China, the worlds largest smartphone market, is more than about geopolitics （地缘政治）. Chinese consumers （消费者） love its flagship, high-end-phones because they have great cameras, cutting edge technology and cost less than the latest iPhones, according to analysts. And by offering a selection of cheaper phones, Huawei is able to target a bigger market.

It also benefited from the troubles this year at ZTE （ZTCOF）, a rival Chinese smartphone and telecommunications equipment maker. ZTE was banned by the US government from buying vital American parts for months last year.

7 . Choosing what to wear can be a tricky problem, especially if you’re a fashion victim. Trying to keep up with the latest styles involves regular visits to the shops and sometimes wasting money on expensive designer clothes. But when the fashion changes, these clothes are forgotten in the back of cupboards gathering dust, or just get thrown away.

There are many stores that now offer cheap “fast fashion”—low-price items that imitate the styles of more expensive designer brands. Environmentalists are angered by the amount of energy involved in making these clothes and that many of them are made from non-recyclable materials. This means that items go into landfill or are just incinerated, which is responsible for 20% of the world’s waste water, and 10% of carbon emissions.

This is something the fashion industry is becoming more aware of and has led to a new crop of biomaterials that replace wasteful textiles like cotton and leather. Examples include Piñatex, a leather-like substance made from deserted pineapple leaves. It’s been used in collections by Hugo Boss and H&M. And there’s mycelium, the root structure of mushroom that’s being used to create food, packaging and textiles.

Cotton is a very resource-intense crop to grow. Eleanor Lawrie says “about 15,000 liters of water are required to make one pair of jeans.” So, buying organic cotton is a better choice. And there is also Tencel, also known as Lyocell, a natural product that’s now growing in popularity.

“But creating sustainable textiles is only part of the battle. Buying second hand and buying fewer clothes are the obvious environmentally friendly choices.” said Dr. Richard from Leeds School of Design “I don’t think you should consider buying any item of clothing unless you commit to 30 years.”

People in China     1    (pay) cash for things for thousands of years, long before other civilizations. Now,     2    (increase), they’re paying with their cellphones. Chinese consumers are basically jumping across plastic, and going straight from cash    3     mobile payments. Chinese spent $5.5 trillion through mobile payment platforms last year, about 50    4    (time) the amount in the U. S., according to reports. Nowhere is the cashless trend     5    (much) obvious than in the eastern Chinese city of Hangzhou, which is home to Alibaba, the world's largest online shopping platform. Its mobile payment app, Alipay, and WeChat Pay,     6     belongs to the country’s leading social messaging platform, together hold a commanding 90 percent of the market,     7    (leave)Apple Pay struggling to make inroads(进展). I recently spent a day in Hangzhou to see     8    easy it was to go cashless, and I found it somewhat ahead of other cities, including Beijing. I rode buses and subways, which all accept Alipay. I even listened to the mournful tunes of a woman performing music on the street for change—or for a scan of a QR code（二维码）    9    (place) beside the change box. Over a bowl of noodles, a restaurateur told me that about half of his customers pay for their meals with cellphones, and that he uses     10    (he) to pay most of the time too. "I don't have to worry about getting counterfeit （伪造的）money, or having to make change, he explained.
