Charlie Chaplin was a {#blank#}1{#/blank#} (humor) actor. He entertained us nonverbal (不用语言的) humor. Born in {#blank#}2{#/blank#} (poor), he became famous for using a particular form of acting in entertaining silent movies. He was {#blank#}3{#/blank#} charming character, well-known throughout the world. He played a poor and homeless person, {#blank#}4{#/blank#} (wear) large trousers, worn-out shoes and a small round black hat {#blank#}5{#/blank#} carrying a walking stick. The character was a social failure in the movies, but he {#blank#}6{#/blank#} (love) by all the people. By overcoming {#blank#}7{#/blank#} (difficult),being kind to people unkind to him, making a sad situation entertaining and eating a boiled shoe, Charlie Chaplin made {#blank#}8{#/blank#}（we）happy and excited. Charlie Chaplin produced, directed and wrote movies in {#blank#}9{#/blank#}   he starred（主演）. In 1972 he was given a special Oscar {#blank#}10{#/blank#} his outstanding work of bringing humor to us all through films.

    While not everyone will have pondered (思索) the subject while staring out of the window during {#blank#}1{#/blank#} flight, the question as to why aeroplanes have circular windows rather than square ones is interesting.

    Over the years, aerospace engineering {#blank#}2{#/blank#} (make) huge leaps in aeroplane technology, meaning planes can carry {#blank#}3{#/blank#} passengers and go faster. The planes have also changed shape to increase safety — including the windows.

    In the 1950s, {#blank#}4{#/blank#} jetliners were starting to become mainstream, the De Havilland Comet came {#blank#}5{#/blank#} fashion. With a pressurised cabin, it was able to go higher and faster than other aircraft.

    {#blank#}6{#/blank#}, the plane had square windows and in 1953 two planes fell apart in the air, {#blank#}7{#/blank#} (kill) 56 people in total.

    The reason for the {#blank#}8{#/blank#} (crash)? The windows.

    {#blank#}9{#/blank#} there's a corner, there's a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress — such as air pressure.

    By curving the window, the stress that would {#blank#}10{#/blank#} (eventual) crack the window corner is distributed and the likelihood of it breaking is reduced.

    How would you feel if you woke up and found your entire computers—including your photos, your recent documents—no longer {#blank#}1{#/blank#} (access)? What if you found out that they had been wiped from your computer, {#blank#}2{#/blank#} (leave) you with nothing but heartache?

    Guess what? It happens to people every single day. Every day, people across the country head into their local Apple store in {#blank#}3{#/blank#} (tear), broken computer in hand, praying as they wait in line that an expensive repair might, just might, recover the priceless, irreplaceable files. A few get lucky. {#blank#}4{#/blank#} for the rest, there's nothing anyone can do {#blank#}5{#/blank#} (help).

    Hasn't it happened to you? If your computer remains unprotected, it will, and it's only {#blank#}6{#/blank#} matter of time. But thanks {#blank#}7{#/blank#} recent breakthroughs in computer backup (备份) technology, you now have a number of options to prepare, and if you're smart, when your computer {#blank#}8{#/blank#} (crash), you shouldn't have any trouble {#blank#}9{#/blank#} (get) 100% of your files back that same day. I'm not talking about an external hard drive. I'm talking about an online backup solution that runs {#blank#}10{#/blank#} (quiet) in the background on your computer. If you have one installed (安装), when your computer crashes, you'll be just one click away from bringing your files back to life.

    One morning, I was waiting at the bus stop, worried about {#blank#}1{#/blank#} (be) late for school.

    There were many people waiting at the bus stop, {#blank#}2{#/blank#} some of them looked very anxious and {#blank#}3{#/blank#}(disappoint), when the bus finally came, we all hurried on board. I got a place next {#blank#}4{#/blank#} the window, so I had a good view of the sidewalk. A boy on a bike {#blank#}5{#/blank#} (catch) my attention. He was riding beside the bus and waving his arms. I heard a passenger behind me shouting to the driver, but he refused {#blank#}6{#/blank#}(stop) until we reached the next stop. Still, the boy kept {#blank#}7{#/blank#}(ride). He was carrying something over his shoulder and shouting. Finally, when we came to the next stop, the boy ran up the door of the bus. I heard an excited conversation. Then the driver stood up and asked,"{#blank#}8{#/blank#} anyone lose a suitcase at the last stop?" A woman on the bus shouted, "Oh, dear! It's {#blank#}9{#/blank#} (I)". She pushed her way to the driver and took the suitcase thankfully. Five others on the bus began talking about what the boy had done and the crowd of strangers {#blank#}10{#/blank#}(sudden) became friendly to one another.
