    While {#blank#}1{#/blank#}(wait) for the airplane to take off,I was happy to get a seat by myself. Just then, {#blank#}2{#/blank#} air hostess approached me and asked,"Would you mind {#blank#}3{#/blank#}(change) your seat?A couple would like to sit together."The only possible seat was next to a girl with her arms in casts（石膏绷带）,a black and blue face,and a sad {#blank#}4{#/blank#}(express)."No way am I going to sit there,"I thought {#blank#}5{#/blank#}(immediate).But a soft voice spoke,"She needs help."Finally,I decided to move to that seat.The girl was named Kathy.She was hurt in a car accident and now was {#blank#}6{#/blank#}her way to treatment. When the snacks and juice arrived,it did not take me long to realize {#blank#}7{#/blank#}Kathy would not be able to feed herself.I considered {#blank#}8{#/blank#}necessary to feed her but hesitated,as it seemed too impolite to offer a service to a stranger.But then I realized that Kathy's need was more important than my discomfort.I offered {#blank#}9{#/blank#}(help) her eat, and although she was uncomfortable to accept,she did as I expected.We became closer and closer in a short period of time.By the end of the five-hour trip,we had become friends.Love sometimes flows beyond human borders and {#blank#}10{#/blank#}(remove) the tear that keeps us separate.When we offer to serve another,we grow to live in a larger and more rewarding world.

    Success never comes easy. How many of you have heard of successful people who haven't made any effort? People often have to overcome failures {#blank#}1{#/blank#}they can accomplish something great. They usually don't find success from the very beginning.

    Van Gogh sold only one painting during his lifetime, but this didn't stop him from completing over 800 painting. Thomas Edison {#blank#}2{#/blank#}(fire) from his first two jobs for lack of competence. Later, as an inventor, he tried 1,000 times {#blank#}3{#/blank#}(create) the light bulb, without success. He was confident in {#blank#}4{#/blank#}(he), and{#blank#}5{#/blank#}(eventual) he did success. When {#blank#}6{#/blank#} (ask), “How did it feel to fail 1,000 times?” Edison replied, “I didn't fail 1,000 times. The light bulb was {#blank#}7{#/blank#} invention with 1,000 steps.

    These successful people have set good {#blank#}8{#/blank#}(example) to us. They wouldn't have achieved their success if they{#blank#}9{#/blank#}(abandon)their dreams. Believe in yourself and try your best, and success will not be far{#blank#}10{#/blank#} you.

    Texting while walking is something that most of us are guilty of．We can't help {#blank#}1{#/blank#}(reply)to that message we just received．However，while it's fun to keep up to what's going on，we may actually put{#blank#}2{#/blank#}(we)in danger．

    A team of researchers from UK recently found people{#blank#}3{#/blank#}use their phones while on the move walk differently．During the research，a group of 21 volunteers{#blank#}4{#/blank#}(ask)to walk around a street with obstacles(障碍物)such as a step.{#blank#}5{#/blank#}volunteers traveled the course a total of 12 times each，either writing or reading a message，making a call，or with no phone at all．It took the volunteers 118 percent {#blank#}6{#/blank#}(long)to complete the course while using a phone．They also paid attention to the travel path 51 percent more when they weren't using a phone．“Although there{#blank#}7{#/blank#}(be)no accidents，we should still be aware{#blank#}8{#/blank#}what's going on around us，”according to Matthew Timmis，co—author of the study．The big risk is suddenly—appearing situations，like someone suddenly walking in front of you．You are not going to be able to respond to that{#blank#}9{#/blank#}(swift)enough，so you may injure yourself or get injured．In a word，these hidden{#blank#}10{#/blank#} (danger)of texting while walking should be recognized to avoid injuries．

    It seems that artificial {#blank#}1{#/blank#} (intelligent) can do much more than what we have ever imagined. From controlling the lighting in our homes to {#blank#}2{#/blank#} (help) us order pizza, AI has become an important part of our everyday life. But what about the more creative works of mankind? Art, music, poetry­these are inspired not by logic or reason, {#blank#}3{#/blank#} by emotion.

    In 2017, researchers in Switzerland created the "deep artificial composer (DAC)", {#blank#}4{#/blank#} can create original music all by {#blank#}5{#/blank#} (it). The scientists trained it to "listen" to over 2,000 different folk songs and {#blank#}6{#/blank#} (base) on this input, the AI taught itself how to get the pitch (音高) and timing and choose the right notes. Besides music, AI already {#blank#}7{#/blank#} (enter) the world of poetry as well. In 2018, Chinese and Japanese researchers wrote an AI program that uses images to write poems. Then the poems were sent to 500 human judges, who were asked to tell {#blank#}8{#/blank#} they were written by a human or a computer. The result showed that as {#blank#}9{#/blank#} as 200 judges mistakenly thought they were written by a human.

    So if you were {#blank#}10{#/blank#} artist or a musician, would you watch out?
