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.

    When I was 14 years old, my best friend {#blank#}1{#/blank#} (drag) me to an after-school dance class, {#blank#}2{#/blank#} I enjoyed so much that I have been dancing ever since. After every dance class, however, I always have to stretch out my legs and back! It feels like as much exercise as {#blank#}3{#/blank#} (go) to the gym—but dancing is not {#blank#}4{#/blank#} (wide) considered to be a sport.

    Many dancers would argue that dancing is a sport, as it requires strong muscles and impressive flexibility. No matter what style of dance you are participating in, you will always be using all of {#blank#}5{#/blank#} (you) muscles while dancing and this can often be for several hours a day.

    On {#blank#}6{#/blank#} other hand, many people argue that dance is an art form. Dances often exhibit emotion (情感), tell {#blank#}7{#/blank#} (story), etc. Dancing to music is creative and visually appealing to the eyes and ears, just like watching a play or a(n) {#blank#}8{#/blank#} (profession) band. The shining costumes, the stage make-up and the big hairstyles are artistic and imaginative.

    However, whether you consider dance to be an art {#blank#}9{#/blank#} a sport, the important thing is to enjoy it! Dancing is a great way {#blank#}10{#/blank#} (make) new friends and exercise!
