China has once again showed its ability to change the world with its “new four great {#blank#}1{#/blank#}(invent)”—high-speed rail, electronic payment, shared bicycle, and online shopping

    China's new-generation high-speed train, the Fuxing, is now one of the {#blank#}2{#/blank#}(fast) trains in the world, which can travel at a speed of 350 km/h. Besides high-speed rail, China {#blank#}3{#/blank#}(improve) people's lives in many other innovative (创新的) ways over the last decade.

    Bike sharing, for example, is not new itself. But China has made {#blank#}4{#/blank#}much more convenient and popular both in China {#blank#}5{#/blank#}overseas. Leading Chinese bike-sharing companies Mobike and Ofo are now operating in foreign countries such as Singapore and Britain.

    And back in China, when riding a shared bike, you can stop {#blank#}6{#/blank#} (buy) and eat whatever you want {#blank#}7{#/blank#}(simple) with a tap of your phone. You could easily pay with your smartphone by {#blank#}8{#/blank#}(scan) the seller's QR code. Cashless payment has grown into a{#blank#}9{#/blank#}(choose)for Chinese  people—even a pancake seller is using Alipay.

    Besides, the four innovative ways of life are most appealing {#blank#}10{#/blank#}youths from 20 countries participating in the Belt and Road innovation, and they wish their countries would emulate(仿效) China in terms of technological achievement

    Increasingly, Americans are becoming their own doctors by going to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店).Some avoid doctors because of the high cost of medical care, especially{#blank#}1{#/blank#} they lack health insurance. Or they may stay away because they find it{#blank#}2{#/blank#}(embarrass) to discuss their weight, smoking, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative {#blank#}3{#/blank#} (experience) in the past. But{#blank#}4{#/blank#}(play) doctor can also be a deadly game.

Every day, more than six million Americans turn to the Internet{#blank#}5{#/blank#}medical answers— and most of them aren't nearly sceptical enough of what they find. A 2002 survey by the Pew Internet &American Life Project found that 72 percent of those{#blank#}6{#/blank#}(survey) believe all or most of what they read on health websites. They shouldn't look up “headache” and the chances of finding {#blank#}7{#/blank#}(rely) and complete information, free from a motivation for commercial gain,{#blank#}8{#/blank#} (be) only one in ten, reports an April 2005 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous{#blank#}9{#/blank#} (inform) exists on the Internet.

    The problem is most people don't know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that's risky, because almost anybody can put up a site that looks authoritative ( 权威的), so it's hard to know if what you're reading is {#blank#}10{#/blank#}(reason) or not,” says Dr. Sarah Bass from the National Cancer Institute.

    China has once again proved its {#blank#}1{#/blank#} (able)to change the world with the “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping.

    They're related to China's high-tech innovation(创新),{#blank#}2{#/blank#} has improved the quality of people's lives, according to a survey{#blank#}3{#/blank#}(make)by the Belt and Road Research Institute of Beijing Foreign Studies University.

    “My wallet is no longer in use. I can buy and eat whatever I want simply with a fingertip on my phone,” said{#blank#}4{#/blank#} university student, adding that “even pancake sellers are using mobile payment.”

    The bikes {#blank#}5{#/blank#}(them)are not new, but the operating model of bike-sharing {#blank#}6{#/blank#}(base)on satellite navigation system, mobile payment, big data and other high technologies.

    China has entered a new innovative era, thanks to the large amounts of capital China has invested in {#blank#}7{#/blank#}(encourage)innovation, said Bernhard Schwartlander, WHO Representative in China.

    {#blank#}8{#/blank#}is increasingly clear that China is innovating and no longer copying western ideas. This is {#blank#}9{#/blank#}(especial)true in mobile, where China is leading in many ways such as…social messaging app WeChat, she said. This is partly because China skipped over the PC era and went directly to mobile. China has the {#blank#}10{#/blank#}(large)mobile use in the world.

    Two ladies living in opposite apartments say "hello" when they meet each other in the corridor. One of them says, "I moved here five years ago, {#blank#}1{#/blank#} I never met you before. Could I ask your name please?" The other says, "I {#blank#}2{#/blank#}(be) here for six years. How should I call you?"

    It seems very ridiculous {#blank#}3{#/blank#} people living so near don't know each other for such a long time. However, you can find this kind of story {#blank#}4{#/blank#} (perform) everywhere. It is the exact {#blank#}5{#/blank#} (reflect) of interpersonal relationships in the modern world. In the modern world most people live in apartments. They close their doors and never go out as soon as they get home from work. If they live alone, they will kill their time {#blank#}6{#/blank#}watching TV or reading magazines. They don't have any connections even with their {#blank#}7{#/blank#}(close) neighbors, who seem no different from people they meet every day in {#blank#}8{#/blank#} street.

    This phenomenon is no good to us, nor to our society. People will feel more and more lonely. The world becomes so indifferent. It's time that we {#blank#}9{#/blank#} (take) some measures to improve it. People living in the same place can {#blank#}10{#/blank#} (organize) to have some activities. We should call on people to be friendly to each other.

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. 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, quit smoking, and manage stress better, they find they feel so much better, so quickly. {#blank#}3{#/blank#} you exercise and eat right, your brain{#blank#}4{#/blank#} (receive) 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 {#blank#}5{#/blank#} (grow) that it actually increased {#blank#}6{#/blank#} size of people's brains! Your face receives more blood flow, so your skin glows more and wrinkles less. You look younger and {#blank#}7{#/blank#} attractive. In contrast, an {#blank#}8{#/blank#} (health) die and smoking speeds up aging because nicotine contributes {#blank#}9{#/blank#} your blood vessel becoming narrower, {#blank#}10{#/blank#}decreases blood flow to your face and makes it wrinkle prematurely.

China successfully landed the Chang'e 4 lunar probe (月球探测器) on the far side of the moon on January 3, 2019, becoming the only country in history  {#blank#}1{#/blank#} (touch) the lunar surface unseen by those on Earth. The far side of the moon has been seen and mapped {#blank#}2{#/blank#}(previous) by astronauts of the Apollo missions. But it is the first time that the moon's far side{#blank#}3{#/blank#}(set) foot on by spacecraft, and the successful landing of Chang'e 4 is seen as a major milestone in space{#blank#}4{#/blank#}(explore).

The Chang'e 4 spacecraft consists{#blank#}5{#/blank#}two parts: a lander and a rover (巡视器). Representing China's{#blank#}6{#/blank#}(new) step in the lunar probe project of all time, it landed at 10: 26 am of Beijing time. Then it sent back a photo of the landing place.{#blank#}7{#/blank#}(shoot) through cameras on the probe's lander, the photo marks the world's first image taken on the surface of the far side of the moon. One of the photos published by the China National Space Administration shows the place{#blank#}8{#/blank#}Chang'e 4's rover — named Yutu 2 — will be heading hours later for{#blank#}9{#/blank#}purpose of conducting further research. The name Chang'e has its roots in the Chinese goddess of the moon. In the ancient tale, Chang'e{#blank#}10{#/blank#}(fly) to the heavens and landed on the moon as her final resting place.
