Starting here,    4     followed the great Yangtze River of the brilliant Chu Civilization. and lake network to expand businesses throughout the entire country. In the Qing Dynasty (1644-1911)， Hankou became one of the four best-known towns in the country. For centuries, Wuhan has been the center of trade and transportation in     5     China. Today it is     6     important center in central China and a feature of Yangtze River cruises(航行) for sightseers and businessmen     7     from Sichuan to Shanghai or Hong Kong.

When the corona virus crisis took hold in early 2020, a group of roboticists (机器人专家) saw an opportunity: Robots are     1     perfect co-workers in a pandemic. “Engineers must use the crisis” they argued in a newspaper, “to speed up the     2     of medical robots,     3     never get sick and can do the dull, dirty, and     4     work that puts human medical workers in harm’s way.” Robot helpers could take     5     temperatures and deliver drugs, for instance. This would free up human doctors and nurses to do     6     they do best: problem-solving and being empathetic (感同身受的) with patients, and skills that robots may never be able to copy.

The     7     developing relationship between humans and robots is so complex that it has developed its own field,     8     as human-robot interaction (相互作用). The primary challenge is this: It’s easy enough     9     robots to get along with humans-make them soft and give them a sense of touch-but it’s another issue entirely to train humans to get along with the machines. With Tug the hospital robot, for example, doctors and nurses learn to treat it     10     a grandparent--sweep all the obstacles of its way and help it get unstuck if you have to.

If you’re in Wuhan, an absolute must-see is the Yellow Crane Tower. Regarded as one of the Four Great Towers of China, the tower stands on the banks of the Yangtze River at the top of Snake Hill.

The Taoist priest visited the pot house regularly for half a year when one day the Taoist said to the son that in order to repay his     7    , he would like to draw a crane     8     the wall of the pot house,     9     would dance at his request.

The Xin family soon became rich and they built the Yellow Crane Tower as a symbol of gratitude to the Taoist priest.

The world’s first ship with     1    intelligent unmanned system was launched in Guangzhou. The ship     2     the world’s first scientific research ship     3    can work by remote control in open waters. It will provide an     4    tool for China     5    out marine scientific research and develop the marine economy.

The equipment on the ship is highly localized (本十化的), because the key parts have all been     6     developed by Chinese scientists. The ship has a     7    of 88. 5 meters, width of 14 meters and a depth of 6. 1 meters. With a broad deck, the ship can carry a dozen different observation instruments. Construction of the ship     8    on July 20, 2022, and it is expected to be put into use by the end of this year. In the future, the use o the ship will be     9    great importance for getting real-time ocean observation information,     10    the level of ocean observation.
