Each summer in the late 1960s，my two sisters and I would take the bus from Arizona to Arkansas to stay with our father.A World War Ⅱ soldier，Dad had many medical problems，any one of {#blank#}1{#/blank#}  could cause many people to lose more than their sense of humor，but not him.

    I have memories of Dad waking us{#blank#}2{#/blank#}  in the morning.He had lost his legs in the war，so it was the wheelchair that kept him {#blank#}3{#/blank#}  (move) around.Holding his cane，which was his{#blank#}4{#/blank#}  (extend) arm，he would roll through the house{#blank#}5{#/blank#} (shout)，“Up，up，up! Get up and face the day! It's a beautiful day！” If we didn't get up right away，he would hit the end of our beds with his cane.

Once when we {#blank#}6{#/blank#} (be) in a store，he found the three of us in the makeup department.When he was {#blank#}7{#/blank#} (tell) that we wanted to buy some makeup，he picked up a bottle and started reading the label out loud.“‘Leaves your skin soft and silky from head to toe.' Well，that leaves half of me out，” he said，laughing {#blank#}8{#/blank#} (delight)．We had to laugh，too.He had a talent for {#blank#}9{#/blank#} (find) humor in everything he did.

    Our father has been gone for a long time now，{#blank#}10{#/blank#}  we still remember the lesson that he taught us：You are only as disabled as you let yourself be.

    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.

    Friends play an important part in our {#blank#}1{#/blank#} (life). Though we may take friendship for granted, we often don't clearly understand {#blank#}2{#/blank#} we make friends. While we get on {#blank#}3{#/blank#}(good) with many people, we are usually friends with only a few—for example, per student usually {#blank#}4{#/blank#} (have) about 6 friends. In all the cases of friendly relationships, two people like one another and enjoy {#blank#}5{#/blank#} (be) together. {#blank#}6{#/blank#}fact, as we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these things are not of great {#blank#}7{#/blank#} (important), {#blank#}8{#/blank#} is more difficult to get on with people when there is an obvious difference in age and background. Compared with marriage, there are no friendship ceremonies to {#blank#}9{#/blank#} (strong) the connection between two people. But the mutual（彼此的）understanding that results from common experiences and emotions does seem to create a powerful bond, {#blank#}10{#/blank#} can overcome difference in background, and break down barriers（障碍）of age, class and race.

    Cao Yuan, a 22-year-old Chinese doctoral student in physics, was on top of {#blank#}1{#/blank#} most important scientists named by the journal Nature in 2018 for {#blank#}2{#/blank#} (discover) a "magic angle" in graphene (石墨烯).

    Cao's discovery takes a huge step in the decades-long search for superconductors (超导体) in the world. Why was Cao able to make the discovery? His teachers think it is Cao's independent learning ability and interest in doing experiments {#blank#}3{#/blank#} matter. His high school physics teacher said Cao had a strong ability to study on {#blank#}4{#/blank#} (he) own and was brave to challenge teachers and ask difficult questions. "Cao is {#blank#}5{#/blank#} (deep) curious about laboratory equipment," his college teacher told Nature. "Every time I go into Cao's office, it's {#blank#}6{#/blank#} a huge mess, with computers {#blank#}7{#/blank#} (pull) apart and pieces of telescope all over his desk."

    At 14 he {#blank#}8{#/blank#} (admit) into the University of Science and Technology of China's School of the Gifted Young, a special school to cultivate {#blank#}9{#/blank#} (teenager) into world-class talents. But Cao doesn't think himself special and often stresses that he is just an ordinary kid who {#blank#}10{#/blank#} (love) reading about science and doing experiments. "After all, we are all humans, with shortcomings and emotions," he once said.
