You know that eating a sensible diet and getting plenty of exercise help make your body healthy and strong.But do you know that there are ways to make your brain healthier and smarter? Here are some steps toward a smarter brain.

Limit your TV viewing

    ① Never spend too much time on TV viewing, for it needs very little brain activities.Your brain will become weak just as your muscles do.If you do watch TV, choose something educational and meaningful.

Travel

    Travelling to another country forces you to see and do things in a fresh way, bringing stimulation to the brain.

    Learn a new language

    Learning a new language involves different learning methods.Learning a language sharpens your brain and helps prevent memory problems that you may meet in later years.

Read often

    As you read, take the time to look up people or places that aren't familiar.Reading makes your vocabulary much larger if you always search for words and definitions that you don't know.Each week, choose an animal, a bird or fish, and read everything you can about it.Stretch your brain as you become an expert on the subject.

Calculate （计算）when you shop

    As you put things in your grocery cart, total everything in your head.See how close you get to the actual total.

    Use your non-dominant（不占优势的）hand

    If you are right-handed, use your left hand for everyday activities, or use your right hand if you are left-handed.Doing familiar things in a different way will make your brain create new neural （神经）networks.

Wechat（微信）

    ② Read messages from various people.They have different interests.And some say that learning to express yourself in just 100 words is a great brain challenge.

    Have a try and do these every day.Little by little you can get into the habit of challenging your brain, and make your brain smarter!

    In recent years, a number of Chinese technological innovation(科技创新) have been making waves around the world. Among them, four stand out. They are known as "four new great inventions" of modern China. They have made our daily lives more convenient

High-speed trains

    China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken China's bullet trains(高铁), according to Xinhua News Agency.

    China is currently working on the next-generation bullet trains that will have a top speed of 400kilometers per hour. By 2020, one-fifth of the country's 150,000-km railway network will be used by high-speed trains. This network will link more than 80percent of major cities across China, said Xinhua.

Mobile payment

    Mobile payment is turning China into a "cashless society" led by third-party payment companies like Alipay. For example, instead of paying y cash, customers now pay for goods simply by typing a short password into Alipay app on their mobile devices.

    Users can also pay their bills through Alipay, such as their water and electricity bills. Alipay also supports cross-border(跨境的)online and in-store payment, which allows users to buy things on international websites and apps.

Shared bikes

    Shared bike services started in Western countries. But China has surprised the world with how quickly it has adopted dockless(无桩的)shared bikes.

    Unlike traditional bike-sharing method, dockless bikes allow users to simply pick up or park a bike on the street through GPS and smartphone To unlock a bike, you just need to scan a QR code on a shared bike with a smartphone app     After you finish riding, you can park it at available parking areas, lock it and pay for ride through mobile payment services.

Online shopping

    With around 751 million internet users, China has long been the world's largest and fastest-growing online shopping market.

    Online shopping now accounts for 15.5 percent of total retail sales in China, according to Xinhua. Thanks to lower costs and fewer licensing requirements(执照要求),it's easier for sellers to open an online shop in China than a brick-and-mortar shop(实体店)。

    It also helped to create jobs of rural areas. In 2016, online shopping created more than 20 million jobs in rural areas, with over 8.1 million running their own online shops, said Xinhua.

    I've always wanted to try rock climbing, but never had the time or money for it. But I've discovered a way to experience the thrill(兴奋，紧张)of climbing rock, without climbing real rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer！Indoor climbers don't climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms, schools and camps have one.

    You can climb indoors at any time of the year, no matter how the weather is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for the rush(刺激感)they get. When I stand at the foot of the wall and look up. I'm always scared, But once I start climbing, fear changes to determination. With my heart pounding(怦怦地跳), I reach the top and look down. I can't stop grinning(咧嘴笑). I did it!

    Indoor climbing is a great workout. Climbing uses muscles that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

    Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls your climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip. But make sure your partner know how to use this equipment. And if you are a first-time climber, get some instruction before you begin.
