If the population of the Earth keeps on increasing at its present rate, there will eventually not be enough resources {#blank#}1{#/blank#} (leave) to support life on the planet. By the middle of the 26^th century, if present trends continue, we {#blank#}2{#/blank#}（use）up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on the earth will make{#blank#}3{#/blank#} necessary for us to look for open space somewhere else. But {#blank#}4{#/blank#} of the other planets in our solar system are capable of supporting life at present. One possible solution {#blank#}5{#/blank#} the problem, {#blank#}6{#/blank#}, has recently been suggested by an American scientist, Professor Carl Sagan. Sagan believes {#blank#}7{#/blank#} before the Earth's resources are {#blank#}8{#/blank#} (complete) exhausted it will be possible to change the atmosphere of Venus and therefore create a new world almost as large as the Earth {#blank#}9{#/blank#}.The difficulty is that Venus is much hotter than the Earth. {#blank#}10{#/blank#}, there is only a tiny amount of water there.

    Every four years, millions of people gather in summer {#blank#}1{#/blank#}(watch) soccer games. This year, the World Cup kicked off on June 14 in Russia.

    Specially prepared for the most exciting sporting event, Live It Up, the official World Cup song, was released on May 25. {#blank#}2{#/blank#}(perform) by US artists Nicky Jam, Will Smith, and Albanian singer Era Istref, the song has a line that goes, "One life, live it up,  because we got one life."

    With a great melody(旋律)and attractive lyrics, the song stands for "the {#blank#}3{#/blank#}(excite), the celebration and the unity {#blank#}4{#/blank#} people all over the world would share during the 2018 World Cup". In fact, the relationship between soccer and music {#blank#}5{#/blank#} (grow) stronger and stronger since the first official World Cup song came out in 1966. As a newspaper The Telegraph said, "Listening to inspiring music encourages people to take more risks."

    One of the greatest soccer {#blank#}6{#/blank#} (coach), Giovanni Trapattoni, even believes that listening to music can teach players great lessons. "It is the intervals(中间休息), speed, and rhythm {#blank#}7{#/blank#} help you learn the logical skills you need to read a game." he said.

{#blank#}8{#/blank#}（actual）, the right music can make all the difference. As Colombian musician Juanes said, soccer and music have a lot {#blank#}9{#/blank#} common. "You need your feet for soccer and you need words for music, but they make us think of one and {#blank#}10{#/blank#} same thing— passion."

    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.

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

Tsinghua University was established in 1911, originally under the name "Tsinghua Xuetang". The school was renamed "Tsinghua School" in 1912. The university section {#blank#}1{#/blank#} (found) in 1925. The name "National Tsinghua University" was adopted in 1928.

Tsinghua University was forced {#blank#}2{#/blank#} (move) to Kunming and join with Peking University and Nankai University to form the Southwest Associated University due to the Resistance War {#blank#}3{#/blank#} the Japanese Invasion in 1937. In 1946 the university was moved back to its {#blank#}4{#/blank#} (origin) location in Beijing after the war.

{#blank#}8{#/blank#} China opened up to the world in 1978, Tsinghua University has developed at a breathtaking pace into a research university. Tens of thousands of students have graduated from Tsinghua since its founding, among {#blank#}9{#/blank#} are many outstanding scholars, excellent businesspersons and great statesmen {#blank#}10{#/blank#} (respect) by their fellow Chinese citizens.
