A smiling face with tears, or “Tears of joy”, was chosen as the most popular emoji globally in 2016, according to a report{#blank#}1{#/blank#}（publish）by Chinese tech startup Kika.

    In 2015,emoji was the country's fastest-growing language in the UK and “Tears of joy”also became the Oxford English Dictionary's word of the year,{#blank#}2{#/blank#}（make）it popular on social media worldwide.

    As a language expert pointed out, the reasons{#blank#}3{#/blank#}this are as follows. For one thing, with the development of the Internet, especially the {#blank#}4{#/blank#}（popular）of smartphones, English alone is proving not enough to meet the needs of 21st-century digital communication. For{#blank#}5{#/blank#}emojis can offer greater freedom than verbal language. Meanwhile, compared with text messages, they are often more intuitive（直观的）and{#blank#}6{#/blank#}（simple）,which is also the reason why more and more People choose{#blank#}7{#/blank#}（express）their emotions and ideas by using emojis.

    Even if you don't send emojis yourself, you will{#blank#}8{#/blank#}（probable）receive them.

    However, nobody can definitely-tell {#blank#}9{#/blank#}emojis will finally come to look something more like traditional language that we understand and use daily some day or they are just in fashion for{#blank#}10{#/blank#}while like many things. “After all, it's an addition to language rather than a language itself,”Dr Drummond says.

    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.

    Happiness can be described {#blank#}1{#/blank#} a positive mood and a pleasant state of mind. There are many factors {#blank#}2{#/blank#}(contribute) to happiness.

    A person in an apparently ideal situation is not {#blank#}3{#/blank#}(necessary) happy. The ideal situation may have little to do with his actual feelings.

    A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}4{#/blank#} are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it {#blank#}6{#/blank#}(believe) that this is mainly.{#blank#}7{#/blank#} they have more opportunity to control their {#blank#}8{#/blank#}(life). Yet people with a high income and a college education may be less happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope)with a health problem can contribute to happiness.

    When in 1984 I. M. Pei, then the most sought-after architect in America, {#blank#}1{#/blank#} (present) his plans for a 70-foot glass pyramid in the 18th-century courtyard of the Louvre, the general{#blank#}2{#/blank#}(react) was anger. Because Mr. Pei was Chinese-American, he{#blank#}3{#/blank#} (apparent) had no under standing of the Louvre, or Paris, or France.

    However, these remarks did not annoy him. With quick enthusiasm and wide smiles, he took them. He had been asked to design {#blank#}4{#/blank#}new entrance for the museum and{#blank#}5{#/blank#} everyone's surprise, instead of adding on some concrete block, he had created a great welcoming space: put a winding staircase underground and capped it with a ray of light {#blank#}6{#/blank#}did not hurt the old facades(外墙).

    When he was a child, his imagination {#blank#}7{#/blank#}( shape) by his family's ancient gardens at Suzhou in Jiangsu. There, he would wander winding{#blank#}8{#/blank#}(path) through fantastic rocks towards pavilions (亭子), unconsciously {#blank#}9{#/blank#} (absorb) the beauty of the surroundings.

    Mr. Pei built a hotel complex at Fragrant Hill outside Beijing, after returning to China in 1974. He regarded this as a chance{#blank#}10{#/blank#} (bring) the Chinese away from their dull eastern European blocks and back to the domestic traditions they had lost.
