High-speed railways, electronic payments, shared bicycles and online shopping are China's four new ways of life. They are most appealing to youths from 20 countries participating {#blank#}1{#/blank#}the Belt and Road Initiative. The new four great inventions are all related to China's high-tech innovation,{#blank#}2{#/blank#}has improved the quality of people's lives, “My wallet is no longer in use. I can buy and eat whatever I want {#blank#}3{#/blank#}(simple) with a tap of my phone,” said Lin Jinlong, an overseas Chinese student from Cambodia,{#blank#}4{#/blank#} (add) that even pancake sellers are using Alipay (mobile payment).

    In {#blank#}5{#/blank#}word, China is leading in many ways. Bike sharing, for example, is not new itself. But China has made it much more convenient and {#blank#}6{#/blank#} (enjoy) both in China and overseas. Leading Chinese bike-sharing {#blank#}7{#/blank#}(company) Mobike and Ofo are now operating in foreign countries such as Singapore and Britain. Users in the countries felt excited and {#blank#}8{#/blank#}(post) photos of themselves riding the Chinese bikes on social media. A growing number of foreigners hope {#blank#}9{#/blank#} (promote) economic development in {#blank#}10{#/blank#} (they) home countries by paying more attention to the achievements of China.

    I am taught by many teachers in my school. Every subject has a {#blank#}1{#/blank#} (differ) teacher, but I like my math teacher{#blank#}2{#/blank#} (well). Her name is Lakshmi, but we usually call her Ma'am. She is our class teacher, too.

    Ma'am {#blank#}3{#/blank#} (join) us last term. She is very kind and her method of teaching is so interesting and simple {#blank#}4{#/blank#} we all can understand what is being taught. Most{#blank#}5{#/blank#} (important), Ma'am teaches us with great patience. {#blank#}6{#/blank#} we do not understand a problem, she will spend extra time {#blank#}7{#/blank#} (explain) about it until we understand it. And we can go to her at any time during school hours for help.

    She also helps us with activities at school. When there is some kind of program, she will be there to help us to get ready {#blank#}8{#/blank#} the show. Even when we go on a picnic, she takes good care of {#blank#}9{#/blank#} (we).

    To me, Ma'am is not only {#blank#}10{#/blank#} good teacher, but also our best friend. I love Ma'am and I wish her a happy life.

    To Be Joyful, To Be Young

    What really works to make sustainable changes in diet and lifestyle? It's probably not what you think. In the past 30 years of conducting clinical research, I {#blank#}1{#/blank#}(learn) that real keys are pleasure, joy and freedom. Joy of living is sustainable; fear of dying is not.

    Why? Because life is to be enjoyed. There's no point {#blank#}2{#/blank#}(abandon) something you enjoy unless you get something back that's even better, and quickly. When people eat more healthfully, {#blank#}3{#/blank#}(quit) smoking, and manage stress better, they find they feel so much better, so quickly. It reconstructs the reason for making these changes from fear of dying to joy of living.

    When you exercise and eat right, your brain receives more blood flow and oxygen, so you become smarter, have more energy, and need less sleep. Two studies showed just walking for three hours per week for only three months caused so many neurons(神经细胞) {#blank#}4{#/blank#}(grow) that it actually increased the size of people's brains!

    Your face receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, lasting emotional stress and smoking reduce blood flow to your face {#blank#}5{#/blank#}you age more quickly. Smoking speeds up aging because nicotine contributes to your blood vessel becoming narrower, {#blank#}6{#/blank#}decreases blood flow to your face and makes it wrinkle prematurely. This is why smokers look years older than they really are.

    One of the most interesting findings was that the mothers' awareness of stress was more important than {#blank#}7{#/blank#}was objectively occurring in their lives. {#blank#}8{#/blank#}(give) a questionnaire, the women were asked to rate on a three-point scale how stressed they felt each day. The women who realized they were under heavy stress had significantly shortened and damaged telomeres(染色体端粒) compared with {#blank#}9{#/blank#}who felt more relaxed. Contrarily, some of the women who felt relaxed {#blank#}10{#/blank#}raising a disabled child had more normal-appearing telomeres.

In other words, if you feel stressed, you are stressed.

    We could learn vocabulary while we are asleep. Researchers showed it is possible {#blank#}1{#/blank#} (learn) new information while sleeping deeply, and recall this information later. They did tests to see {#blank#}2{#/blank#} a person could remember new words and their translations while sleeping. The answer is yes. The language areas of the brain remember vocabulary during sleep, especially during deep sleep. While sleeping, our brain switches on for about half a second and then switches{#blank#}3{#/blank#} for half a second. The active state {#blank#}4{#/blank#}(call) "up-state". This is how our brain could learn new vocabulary.

    I am now on my year abroad in Germany as part of my university course. At the {#blank#}1{#/blank#} (begin) of my time here, I had the chance to meet so many new people and make lots of new friends. It is almost like {#blank#}2{#/blank#} (start) a new life and can make you feel nervous and lonely at first. But I knew that when I moved to Germany I had to be open and friendly. This is {#blank#}3{#/blank#} (certain) what I have done since moving here and I have made some great friends along the way.

    Next week a friend of {#blank#}4{#/blank#} (I) is moving to Spain for the next part of her year abroad. She will be living near a beach and have a lot of fun. But I am also {#blank#}5{#/blank#} (concern) about her as she will have to start a new life in another new country. She said that she {#blank#}6{#/blank#} (want) to go back in time very much.

    In order {#blank#}7{#/blank#} (say) goodbye to her, a group of friends and I had a surprise party. We made her a scrapbook (剪贴簿) with photos and memories of her time here so {#blank#}8{#/blank#} she could take it along! We hope that she has {#blank#}9{#/blank#} wonderful time in Spain and that she will get along well {#blank#}10{#/blank#} her new classmates and settle into her new home.
