Riding a Mo-bike on the street, you might hear some people speaking Chinese aloud. Turning to the right, you see a Sichuan-Style restaurant. After walking into a store, you see that Huawei Smart-phones are on sale.
But you’re not in China — you’re in Manchester in Britain. In fact, you might see similar things in many other cities. 1.
Chinese food has been enjoyed in Western countries for a long time.
2.
“One example is the meat,” said Yin Hang, who is studying at the University of Wollongong(伍伦贡（澳大利亚东南部港市）) in Australia.
“We like to eat meat with the bone in, but people here don’t. So Chinese restaurants provide big pieces of meat without bones, even for fish.”
3. In many cities in Europe, stores sell TCL televisions, Haier fridges and Lenovo computer, reported Reuters.
More than half of US-owned drones(无人机) are Chinese models, according to China Daily. 4.
In the past, most western people thought Chinese goods were cheap and unreliable. 5. “Made in China” has become cool and more people trust Chinese brands.
For example, Huawei, one of China’s Smart-phone makers, caught up with Apple in global Smart-phone sales for the first time in June and July, behind only Samsung, noted consulting(咨询) firm Counterpoint Research.
“They are beautiful and offer some unique features (特点)American phones don’t have,” CNN once said about Chinese Smart-phones.

The weather is getting hotter. You are thirsty after playing basketball or riding home from school. A cold drink may be just the thing. But be careful of what you are drinking. Something that looks cool may not be good for our health. There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.
