No one knows {#blank#}1{#/blank#}(exact) how the earth began, as it happened so long ago. However, according to a widely {#blank#}2{#/blank#}(accept) theory, the universe began {#blank#}3{#/blank#}a “Big Bang” that threw matter in all {#blank#}4{#/blank#}(direction). For several billion years after the “Big Bang”, the earth was still just a cloud of dust.{#blank#}5{#/blank#} it was to become was {#blank#}6{#/blank#}(certain) until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so {#blank#}7{#/blank#}(violence) that it was not clear {#blank#}8{#/blank#}the shape would last or not. It exploded loudly with fire and rock. They were in time {#blank#}9{#/blank#}(produce) carbon dioxide, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water began to appear on {#blank#}10{#/blank#} surface.

    The carrier rocket sent a Shenzhou-ll spacecraft（航天器）with astronauts Chen Dong and Jing  Haipeng into space. The rocket was fired from the Jiuquan Satellite Launch Center{#blank#}1{#/blank#}the Gobi desert. After two days in Earth's orbit, the spacecraft{#blank#}2{#/blank#}(be) to link up with China's space  laboratory, called the Tiankong-2,{#blank#}3{#/blank#}name means“Heavenly Palace 2". The lab {#blank#}4{#/blank#} (place) into orbit last month.

    The astronauts will spend 30 days on the Tiankong-2. They plan to perform {#blank#}5{#/blank#} (science) and spacecraft-related experiments and test systems for a future space station. In{#blank#}6{#/blank#}words, the Tiankong

    2 laboratory will not be part of that space station. Its main goal is to practice the techniques and the{#blank#}7{#/blank#}(technology) that they will be {#blank#}8{#/blank#}(use)to build and operate that final space station.

    It is predicted that the Chinese space station will be built mostly by machine. China hopes to have the space station{#blank#}9{#/blank#} (complete) by 2022 and it is expected to operate for at least 10 years.

    China also plans to land a probe（探测器）on Mars by 2020. Until now, China has completed a total of five manned space missions. And, in 2003,it {#blank#}10{#/blank#} (successful)landed a probe on the moon.

    Chengdu has dozens of now millionaires, Asia's biggest building, and fancy new hotels. But for tourists like me, pandas are its top{#blank#}1{#/blank#}(attract).

    So it was a great honor to be invited backstage at the not-for -profit Panda Base, where ticket money helps pay for research, I {#blank#}2{#/blank#}(allow) to get up close to these cute animals at the 600-acre centre. From tomorrow, I will be their UK ambassador. The title will be{#blank#}3{#/blank#}(official)given to me at a ceremony in London. But my connection with pandas goes back {#blank#}4{#/blank#} my days on a TV show in the mid-1980s,{#blank#}5{#/blank#} I was the first Western TV reporter{#blank#}6{#/blank#}(permit) to film a special unit caring for pandas rescued from starvation in the wild. My ambassadorial duties will include {#blank#}7{#/blank#} (introduce) British visitors to the 120-plus pandas at Chengdu and others at a research center in the misty mountains of Bifengxia.

    On my recent vigil, I held a lively three-month-old twin that had been rejected by {#blank#}8{#/blank#}(it) mother. The nursery team switches him every few{#blank#}9{#/blank#}(day) with his sister so that while one is being bottle-fed,{#blank#}10{#/blank#} other is with mum-she never suspects.

    According to Xinhua News Agency, the Palace Museum and Huawei signed a strategic cooperation agreement on March 15. The two sides will set an example {#blank#}1{#/blank#} 5G application.

    The Palace Museum received more than 17 million visitors in 2018, {#blank#}2{#/blank#}(make) it the most visited museum in the world. In the past 20 years, an office information network covering the whole museum {#blank#}3{#/blank#}(build) gradually. The museum has developed an App that provides an in-depth {#blank#}4{#/blank#}(explain) of cultural relic information and cultural services. Also, the museum has research on the application of VR, AR, AI and other {#blank#}5{#/blank#}(technique) in museums.

    {#blank#}6{#/blank#}signing of the agreement marks a new chapter in the strategic cooperation between the Palace Museum and Huawei Technologies Co. So, Huawei will make efforts {#blank#}7{#/blank#}(accelerate) the intelligent construction of the Palace Museum.

    "The 600-year-old Palace Museum has never been so close to science and technology," Shan Jixiang said {#blank#}8{#/blank#}(proud), director of the Palace Museum.

    Shan shared many ideas about the 5G Palace Museum. With the help of advanced technology, {#blank#}9{#/blank#}is expected that in the future, audiences around the world will be able to experience and visit the Palace Museum, whether it is a field trip or a virtual tour. Also, the use of AI technology provides a {#blank#}10{#/blank#}(broad) platform and stronger knowledge support for cultural relics among young people.
