Two weeks ago, we reported about developments with {#blank#}1{#/blank#} (electricity) planes and flying cars. That technology could bring change to commercial and personal travel. Last week, two {#blank#}2{#/blank#}(company), Kitty Hawk and Uber, announced their plans to bring flying cars to reality. Sooner {#blank#}3{#/blank#}you think, flying cars may appear in the skies. Imagine never {#blank#}4{#/blank#}(have) to worry about traffic, stoplights, or road construction. A flying car could get somewhere much faster than one traveling by road.

    Kitty Hawk is a start-up tech company supported by Google co-founder. Its first flying cars,{#blank#}5{#/blank#}travel at a speed of up to 40 kilometers an hour,{#blank#}6{#/blank#}expect) to go on sale by the end of 2017. Uber expects to launch flying taxis in Texas and Dubai by 2020.{#blank#}7{#/blank#}says its flying taxis could travel up to 241 kilometers an hour, with the travel time {#blank#}8{#/blank#}(reduce) from 2 hours on the road to 15 minutes in the air between San Francisco and San Jose, California. Riders could use the Uber app {#blank#}9{#/blank#}(book) a flying taxi to take them to their destinations. It is estimated that flying taxi travel will be much {#blank#}10{#/blank#} (expensive) compared with road taxi travel.

    Itzhak Perlman, a famous violinist, came on stage to give a concert. He was stricken with polio（小儿麻痹症）as a child, so getting on stage is no small {#blank#}1{#/blank#} (achieve).

    The audience sat quietly while he made his way across the stage {#blank#}2{#/blank#} his chair and began his play. But this time,{#blank#}3{#/blank#} went wrong. Just as he finished the first part, one of the strings on his violin {#blank#}4{#/blank#}(break). We thought that he would have to stop the concert. But he didn't.{#blank#}5{#/blank#}, he waited a moment, closed his eyes and then signaled the conductor to begin again.

    {#blank#}6{#/blank#} (power) and pure, his performance attracted all the attention.

    Of course, anyone believes {#blank#}7{#/blank#} impossible to play a harmonious work with just three strings. I know that, and you know that, but that night Itzhak Perlman refused {#blank#}8{#/blank#} (know) that.

    When he finished, people rose and cheered.

{#blank#}9{#/blank#} (smile), he wiped the sweat and said, “You know, sometimes it is the artist's task to find out how much music you can still make with{#blank#}10{#/blank#} you have left.”

    Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know) as the leader of the research group than first cloned a female lamb {#blank#}2{#/blank#} (call) Dolly in 1996. Dolly became famous and pictures of her appeared on the {#blank#}3{#/blank#} (cover) of magazines all over the world. The {#blank#}4{#/blank#} (possible) of reproduction without a male and female being involved also made her the focus of a moral debate. For scientists, however, the cloning of dolly using the DNA of an adult cell was a breakthrough {#blank#}5{#/blank#}showed the cloning of special animals was possible.

    However,{#blank#}6{#/blank#}Wilmut think unlikely is human cloning. He says {#blank#}7{#/blank#} (undertake) the procedure with humans would require 29 surrogate（替代的）mothers and 300 eggs. Of those 29, 28 would be bound {#blank#}8{#/blank#}(experience) failure and suffer physically and emotionally. He says he is also concerned about the psychological and {#blank#}9{#/blank#}(society) consequences a cloned might have to go through. For these reasons, he is not{#blank#}10{#/blank#} favor of it.

    As one of "China's new four great inventions", China's high-speed rail eyes the world again with "Fuxing". It is proud of a top speed of 400 km/h and a continuous speed of 350 km/h. It is {#blank#}1{#/blank#} (total) designed and produced by Chinese engineers {#blank#}2{#/blank#} any help from the West.

    China's high-speed train is not only known for its amazing speed, but also for its safety and comfort. Last year, it safely carried 1.4 billion {#blank#}3{#/blank#}, or the total population of Africa and South America {#blank#}4{#/blank#} (combine).

    In 2015, a video taken by a Swedish traveler became popular on social media both at {#blank#}5{#/blank#} and abroad. In the nine-minute video, a coin stood upright all the time on a fast-running high-speed train. It shows the steadiness (稳定) of China's high-speed train, {#blank#}6{#/blank#} (give) visitors a comfortable travelling experience.

    The service on China's high-speed rail is still improving. The new bullet train plans to increase the height, and the Wi-Fi network will {#blank#}7{#/blank#} the whole train. Its air conditioning system is designed to reduce the influence of the external pressure wave {#blank#}8{#/blank#} the train is passing through tunnels, easing {#blank#}9{#/blank#} (comfort) of ears.

    The rapid development of China's high-speed rail in the past five years {#blank#}10{#/blank#} (mark) China's increasing strength in technology and innovation. It has become a new symbol, showing China's great progress to the world.

    Today, it is not rare that people may lose their jobs, so it is perhaps the time to consider the experience of unemployment. What are the first feelings? Well, {#blank#}1{#/blank#} (lose)a job, or not being able to find one, almost always causes sadness.

    If you've lost a job, the first feeling is often that of{#blank#}2{#/blank#}(disappoint)  The days seem{#blank#}3{#/blank#}(be)getting longer and the time becomes {#blank#}4{#/blank#}(hard)to fill in. Some people may {#blank#}5{#/blank#}(have)difficulty in sleeping and eating. They feel depressed, often isolated and lonely. Others may lose confidence in themselves. They are no longer certain about {#blank#}6{#/blank#}(they)own feelings. Despite all these problems, unemployment may bring good feelings, too. It's nice to be able to lie in bed in the morning, spend more time{#blank#}7{#/blank#}your family and relatives, and have more time to think. It can be a chance for a fresh start. You can use the time to consider{#blank#}8{#/blank#} you really want to get from life and how you can get it. Also you can use the time to plan how to find {#blank#}9{#/blank#} new job, learn a new skill, or see if you can run your own business and become a success. {#blank#}10{#/blank#}(possible), a new and better job is already waiting for you.
