China, which takes pride in inventions in ancient times, has once again shown its ability {#blank#}1{#/blank#}(change)the world with its “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping. The “new four great inventions” are all related to China's high-tech innovation(创新), {#blank#}2{#/blank#}improved the quality of people's lives. “My wallet is no longer in use. I can buy and eat {#blank#}3{#/blank#}I want simply with a tap of my phone,” said Lin Jinlong, {#blank#}4{#/blank#}overseas Chinese student from Cambodia,{#blank#}5{#/blank#}(add) that “even pancake sellers are using Alipay (mobile payment). We can also order food at home, and it is of great {#blank#}6{#/blank#}(convenient). If I were at home in Cambodia, I would have to go outdoors.” The bikes themselves are not new, but the operating model of bike-sharing is based {#blank#}7{#/blank#}satellite navigation system, mobile payment, big data and other high technologies. It is{#blank#}8{#/blank#}(increase) clear that China is innovating and no longer copying Western ideas. This is partly because China skipped over the PC age and went directly to mobile. China has the{#blank#}9{#/blank#}(large) mobile use in the world.

    In terms of the “new four great inventions”, Charlie Dai, principal analyst of American market research company Forrester, said, “These products and service{#blank#}10{#/blank#}(improve) customer experience so far, improving national and global economy at the same time”.

    Dujiangyan was built over 2,200 years ago in what is now Sichuan Province in Southwest China. It is {#blank#}1{#/blank#} oldest man - made water system in the world. This amazing engineering achievement is still used today to irrigate over 6,000 square kilometers of farmland, take away floodwater and provide water for fifty {#blank#}2{#/blank#} (city) in the province.

    In ancient times, the region in {#blank#}3{#/blank#} Dujiangyan now stands suffered from regular floods {#blank#}4{#/blank#} (cause) by the overflow from the Minjiang River. Li Bing, the governor of the region, together with his son, decided to find a way to solve the problem.

    The simplest way was to build a dam, {#blank#}5{#/blank#} this would ruin the Minjiang River. So Li designed a series of channels that would take away the floodwater while leaving the river flowing {#blank#}6{#/blank#} (free). Better still, the extra water could be directed to the dry Chengdu Plain, making it {#blank#}7{#/blank#} (suit) for farming.

    Once the system was finished, no more floods occurred and people were able to live peacefully. Today, Dujiangyan {#blank#}8{#/blank#} (admire) by scientists from around the world because of one feature. {#blank#}9{#/blank#} (like) modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally, making it possible for ecosystem and fish populations {#blank#}10{#/blank#} (exist) in harmony.

    The earth, the planet on {#blank#}1{#/blank#} we are living, is the third planet from the sun. It came from the shrinking (收缩) of a vast cloud of dust and gas in outer space. Many scientist believe that the earth, as well as the sun and the other planets in our solar system, {#blank#}2{#/blank#} (form) at least five billion years ago. The earth is slightly flattened at the North and South Poles, {#blank#}3{#/blank#} it would look like a perfect ball if you were far out in space.

Invisible People

If you have the time, check out an amazing YouTube channel that I recently found {#blank#}1{#/blank#} (call) "invisible people". It's a channel with {#blank#}2{#/blank#} (hundred) of interviews of homeless people {#blank#}3{#/blank#} share their story and how they survive day to day.

The man who operates the channel {#blank#}4{#/blank#}(be) formerly homeless and has devoted his life to helping {#blank#}5{#/blank#} homeless, The name "invisible people" certainly suits the channel well. For indeed there are so many "invisible" beings who are suffering every day, both humans and animals, and yet our {#blank#}6{#/blank#} (social) either pays little for people to {#blank#}7{#/blank#} (cruel) treat and kill animals, or completely {#blank#}8{#/blank#} (ignore) those who are in desperate need.

Occasionally, someone who watches the videos posted on that channel is near one of the people interviewed and is able {#blank#}9{#/blank#} (help) in some way. Some of the videos are truly heart-breaking but it's important to see what people go through. We can't turn a blind eye or treat them as if they're invisible. We cannot behave as it's been said, "Worship a homeless man on Sunday, and then ignore a homeless man {#blank#}10{#/blank#} Monday."
