Huawei has joined the list of companies that want to be all about artificial intelligence.     1     is known to all, Huawei Mate60 pro has become a hit recently. Early     2    , Huawei announced the pre-order of its high-end mate 60 smartphone series,     3     (say) it will let some consumers experience the “most powerful” high-end mate series ever.     4     (remarkable), Huawei has made a comeback.   

The latest Huawei Mate60 pro,     5     (price) at 6999 yuan ($960.52), is the world’s first for-public use smartphone, which is much     6     (advance) than the previous products. The device     7     (equip) with a domestically made 5G chip, supports satellite calls and runs on Huawei’s newest Harmony4.0 operating system.

Huawei has been committing     9     (it) to innovation and laying emphasis on artificial intelligence. It is amazing that Huawei should make so major     10     breakthrough in such a short time.

The Shenzhou-12 spaceship     1     (launch) successfully on June 17, sending three taikonauts to its permanent space station called Tiangong, or Heavenly Palace. The spacecraft docked with the core module Tianhe about six-and-a-half hours after launch. It is China's seventh crewed mission to space and the first during the construction of China's space station. While     2     (stay) in orbit, the crew will carry out various experiments and perform two long-duration spacewalks,     3     will enable the China Manned Space Agency to accumulate (积累) experience to prepare for the future construction of the space station.

Over the past few years, the interest in exploring Mars has grown, with some important     1     (discovery) about it. They raise further questions about the past atmosphere of Mars and scientists ultimately want to know whether or not it was     2     (suit) for life.

Images taken by the European Space Agency’s Mars Express satellite show the marks that     3     ancient network of rivers left on the     4     (planet) surface. The valleys formed as they would on earth,     5     a strong flow of water carving its way through the landscape.

    6     is less clear is where the water came from. Due to a lack of knowledge about the past climate of Mars, scientists cannot tell whether it came from melting glaciers (冰川), groundwater     7     something unheard of, though some researchers are doubtful whether liquid water was responsible for the marks     8     (see) by the satellite. They say other materials such as sand or dust can flow like a liquid and produce similar results.

Mars formed more than 4.5 billion years ago and there is no liquid water on the surface of it today. But scientists generally believe it     9     (go) through an early wet and warm era that ended after 1.5 billion to 2.5 billion years,     10     (leave) the planet extremely dry and cold.

Since the beginning of time, exploring the Universe has been a dream of humankind. Human     1     (curious) has fuelled interest in exploring and discovering new worlds, pushing the boundaries of     2     known, and expanding scientific and technical knowledge.

States and space agencies     3     (work) on space exploration since the first space launch. The first space launch led to the first human space flight,     4     led to the first moonwalk. Nowadays focus has shifted to joint human and robotic missions, near - Earth asteroids (小行星), Mars and destinations beyond our own solar system.

Space exploration and the innovation     5     (involve) in it are essential drivers for opening up new areas in space science and technology. That produces new partnerships     6     develops capabilities that create new opportunities for     7     (address) global challenges. Space exploration also motivates young people     8     (pursue) education and careers in science, technology, engineering and mathematics (the STEM disciplines).

Though the precise nature of future benefits from space exploration is not easily predefined (预先确定), current trends suggest that significant advantage may     9     (find) in areas such as new materials, health and medicine, transportation and computer technology. As the benefits of space exploration and innovation become     10     (well) known, increasingly more countries and non - governmental entities are interested in engaging in exploration and innovation.
