Fifty years ago, China successfully launched its first satellite, Dongfanghong 1, and started     1     new chapter in space exploration.     2     (mark) its 50th anniversary, the China National Space Administration announced the name for the country’s Mars planetary exploration program on April 24. The mission, Tianwen got its name from a long poem Tianwen     3     (write) by Qu Yuan, a famous poet of the Warring States Period. In the poem, Qu raised a series of questions     4     (concern) the sky, stars, natural phenomena, myths and the real world, reflecting his doubts on traditional ideas     5     his pursuit of truth. So far, China     6     (make) remarkable progress in space exploration. In 1970, China launched its first man-made Earth satellite, becoming the fifth country in the world to launch man-made satellites     7     (independent). Over the past few years, China’s missions, including the Shenzhou and Change series were designed to explore outer space, expanded     8     (mankind) understanding of Earth and the universe. This time, the Tianwen series will carry out the first Mars exploration mission,     9     represents a milestone for China’s move toward deep space. With the names deep roots     10     Chinese traditional culture, Tianwen demonstrates the determination and perseverance of Chinese people to move further into deep space.

One area in which AI (Artificial Intelligence) influences global health is in the field of epidemiology(流行病学). A start-up has     1    (success) combined public health data with AI    2    (create) a prediction engine capable of anticipating epidemics months in advance with great     3    (accurate). Another field where medical AI is making rapid advances     4    (be) in diagnostics. Doctors base a lot of decisions    5    information from X-ray, CT and MRI images. Speeding up diagnoses from patient    6    (scan) can rapidly improve patient care and outcomes. Governments in many countries face the prospect of ageing populations.So    7    we will probably see is the expansion of AI services, including robotic helpers. Robots     8    (design) specifically to interact with people could help solve the problems of isolation and loneliness that affect many older people. Pet androids like Aibo provide companionship and learn from    9    (they) interactions about each owner’s preferences. More humanoid robots are able to provide social interaction, be a personal assistant and look after     10    elderly, according to its makers.
