Domestic robots such as the Roomba have already established themselves in the marketplace. Common household appliances such as toasters and microwaves {#blank#}1{#/blank#}(fit) with microprocessors, effectively making them robots, which are bound to do as ordered. The military has begun automating (自动化) many of its frontline systems. The future is wide open for more exploration of these{#blank#}2{#/blank#}(device).

    Automatic factories were some of the first to implement (实施，运用) robotics on the assembly line, performing tasks too dangerous or delicate for humans{#blank#}3{#/blank#}(accomplish). This has continued with whole factories{#blank#}4{#/blank#}(begin) to be automated. IBM has instituted a “lights off' factory in Texas that is {#blank#}5{#/blank#}(complete) automated. Recently Caterpillar{#blank#}6{#/blank#}(announce) plans to operate robotic heavy machinery by 2021, and has already begun transferring much of their crane operations to remote-controlled robots{#blank#}7{#/blank#}obey the orders from computer directions. The medical industry has taken advantage {#blank#}8{#/blank#}robotic surgery assistants for years, most notably the Da Vinci surgical (外科的) helper. With rising health care costs{#blank#}9{#/blank#} the increasing needs of an aging population, hospitals are planning vast expansion in the areas of {#blank#}10{#/blank#}(talent) robotics.

    Qingdao lies in the east of Shandong Province. As we all know, it is an important port city and it is an economic and {#blank#}1{#/blank#}(culture)center. It is also home to the Tsingtao Brewery Co. Ltd. and the {#blank#}2{#/blank#}(large)international beer festival in China. Of course, Qingdao is a very beautiful city, too. Many places around the city are well worth {#blank#}3{#/blank#}(visit).Every year, the festival {#blank#}4{#/blank#}(hold)on schedule. Millions of visitors {#blank#}5{#/blank#} come from the world go to the city during the festival.

    It is very convenient to go to Qingdao. It is {#blank#}6{#/blank#}(rough)650 kilometers from Beijing with an average travel time of one hour and 10 minutes by air and five hours by high-speed train. It is about 740 kilometers from Shanghai, and it {#blank#}7{#/blank#}(take)about one hour and 25 minutes by air. There are also frequent direct {#blank#}8{#/blank#}(flight)from Qingdao to the Republic of Korea and Japan. The city's airport is connected {#blank#}9{#/blank#} 66 domestic cities and 12 overseas cities, with a great number of planes arriving {#blank#}10{#/blank#} taking off each week. Warmly welcome to Qingdao!

    If a little humanlike robot begged you not to shut it off, would you show sympathy?

    In an experiment {#blank#}1{#/blank#} (intend) to find out how people treat robots when they act like humans, many participants struggled to power down a begging robot named Nao. {#blank#}2{#/blank#} experiment was conducted by researchers in Germany, whose findings {#blank#}3{#/blank#} (publish) in the scientific journal PLOSOne.

    Nao, {#blank#}4{#/blank#} was designed to beg about half of the participants not to switch it off but not the other half, was used {#blank#}5{#/blank#} (measure) if his begging affected how people reacted.

    In one previous experiment, researchers found that people preferred communicating with robots with complementary (互补的) personality characteristics to {#blank#}6{#/blank#} (they) own. And since robots can exhibit social characteristics either {#blank#}7{#/blank#} (speak) with human voices or taking the shape of a human body, the research suggests that people tend to react “{#blank#}8{#/blank#} (especial) social to them.”

    The researchers said a possible {#blank#}9{#/blank#} (explain) for their results was that people regarded Nao's begging {#blank#}10{#/blank#} “a sign of making its own decision.”

    Have you ever wondered{#blank#}1{#/blank#}children always seem to have bas of energy and never run out of steam? Researchers have discovered that children have levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot {#blank#}2{#/blank#}(quick)than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to {#blank#}3{#/blank#} of athletes. Rwsearcher Dr Sebastien Ratel suggested they{#blank#}4{#/blank#}(find)the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. The children also recovered very quickly—even faster than the well-trained adult endurance athletes.

    The researchers hope that{#blank#}5{#/blank#}(they)finding will help scientists have a better {#blank#}6{#/blank#}(understand) of how the human body changes with age. It could lead to advantages in the fight{#blank#}7{#/blank#}diabetes and other diseases. Dr Ratel said the research was{#blank#}8{#/blank#}(particular)important as more children were become less active. He warned." With the diseases related to physical inactivity{#blank#}9{#/blank#}(rise), know the changes with growth that might contribute to the risk of disease."{#blank#}10{#/blank#}is helpful for children to maintain their fitness as they grow up and play as much as they could so they renin healthy as adults.

    Lang Ping and Michael Jordan are masters in their sports and also set good examples for others.

    Lang ping is loved by fans at home and abroad. When the Chinese team was preparing for the 2015 World Cup, her determination {#blank#}1{#/blank#} (test). Two players had to leave. Losing two important players was {#blank#}2{#/blank#} big challenge, but Lang Ping did not lose heart. She knew her young players could win {#blank#}3{#/blank#} they worked together{#blank#}4{#/blank#}a team. Two weeks later, they were world champions!

    Michael Jordan who became {#blank#}5{#/blank#}(know) as "Air Jordan" changed basketball with his graceful moves and jumps. His skills were {#blank#}6{#/blank#} (impress), but the mental strength that he showed made him unique. He always seemed to find a way {#blank#}7{#/blank#} (win). Jordan says the secret to his success is learning from his {#blank#}8{#/blank#} (fail). Losing games taught him to practice even{#blank#}9{#/blank#}(hard) than before. In life, Jordan has learnt to share his success with others. The Boys and Girls Club which he started in Chicago {#blank#}10{#/blank#}(help) young people since 1996.

    They are our pride and their legends continue.

Comets are among the most beautiful and interesting {#blank#}1{#/blank#}(sight) in the universe. For centuries, people {#blank#}2{#/blank#}(show) great interest in studying them. In 1682, Edmund Halley, an astronomer, noticed a comet that was especially bright and large. Based on his calculations, Halley predicted that this bright comet would return in 1758 or 1759—this was about 75 years {#blank#}3{#/blank#} he first saw the comet. The comet really returned on time and it was named "Halley's Comet" in honor of Edmund Halley.
