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.

    Mobile phones are becoming more and more popular not only with{#blank#}1{#/blank#}(grown-up) but also with students. Meanwhile,they also{#blank#}2{#/blank#}(become) a problem for middle schools in the past few years.Some children have got mobile phones{#blank#}3{#/blank#}Christmas or birthday gifts,and more will still want them.

    Many like SMS because it is{#blank#}4{#/blank#}(ease) and quick.Some parents felt happy because they could communicate with their children.Some teachers said mobile phone use{#blank#}5{#/blank#}(be) a distraction（分心的事）to students during school hours and{#blank#}6{#/blank#}also gave them much trouble in their classrooms.Sometimes students might use phone messages{#blank#}7{#/blank#}(cheat) during exams.A new study found that some teenagers sending messages in class even hurt their fingers because they can't stop{#blank#}8{#/blank#}(send) SMS.

    Many teachers suggested that students should not have phones at school,but if there was a good reason,they could leave their phones at school office.And even they can use the telephone in the teachers' office instead.Many people think they understand the reason{#blank#}9{#/blank#}parents would want their children to have them,but they agree schools should tell the students{#blank#}10{#/blank#}(use) their mobile phones at proper times.

    Recently a really strange thing happened in a middle school in China's Hubei Province. Over 600 students at the school took part in a "caring for an egg like a baby"{#blank#}1{#/blank#}(active). in which they were asked to keep an egg close at hand for a month{#blank#}2{#/blank#}breaking it.

    "It's hard for parents to bring up their children{#blank#}3{#/blank#}many students just ignore it, " said Liu Kang, the school's director. "They should{#blank#}4{#/blank#}(teach) to be grateful to their parents,who have given them life but ask for nothing in return ."

    Li Ming is one of the students. His egg didn't break during the month, but he felt{#blank#}5{#/blank#}(exhaust). "I now understand what great difficulty my parents have had{#blank#}6{#/blank#}（bring）me up. I'll do all I can to make their life easier and{#blank#}7{#/blank#}(comfort) when I grow up,”promised the 13-year-old boy.

    {#blank#}8{#/blank#}(luck), about 450 students broke their eggs. Yan Yueming broke his egg after just five days, which made him frustrated. He said,”I can't imagine {#blank#}9{#/blank#}sad my parents would be if there was something wrong with me, their ‘egg'! It is now time I did something{#blank#}10{#/blank#}return for their love,”said Yan.

    The saying “last man standing” refers to a(n){#blank#}1{#/blank#}(compete), contest, or other situation where the field of participants is narrowed until only a single individual remains. Occasionally, the term may be used to describe a winning couple or team rather {#blank#}2{#/blank#}an individual

    The exact origins of the term are {#blank#}3{#/blank#} (certain). Some believe the term {#blank#}4{#/blank#} (original) applied to the last boxer to remain during a match. Others claim the term came from old - fashioned spelling bees, where participants either gave up {#blank#}5{#/blank#} were judged “out” and asked to sit. Perhaps the most widely use of the term is in connection with a tontine (联合养老制), an agreement in{#blank#}6{#/blank#} a number of persons collectively own something of value, often land. Interest in a tontine cannot {#blank#}7{#/blank#} (pass) to another party, so the last man standing, in this case the last person alive gets the entire interest. Throughout history, tontines have been dangerous investments.

    Today, the term is used in a number of {#blank#}8{#/blank#} (situation). It may refer to the winner in any {#blank#}9{#/blank#} (give) contest. It may even refer to the last person to continue his attempt {#blank#}10{#/blank#} (achieve) a goal after the others have given up.
