Traffic is a very important part in daily life.Nearly everyone complains about being stuck in traffic so much{#blank#}1{#/blank#}people are making it possible that the future city will have no traffic at all.H.G Wells,in his book.The Sleeper Awakes,tells something about the traffic.In the streets of that future London there will be no vehicles.The city{#blank#}2{#/blank#} (provide) with moving roads.One side of the road travels{#blank#}3{#/blank#}one direction;{#blank#}4{#/blank#}other side moves the opposite way. Anyone who wants to go to another part of the city steps on the moving “way” and sits on one of the seats until he arrives.He has none of the troubles,{#blank#}5{#/blank#}a private car brings with it: whether there is enough petrol,whether the tyres are all right,and where to park it.The moving way is always at his service,always moving{#blank#}6{#/blank#}(silent) along,always ready{#blank#}7{#/blank#}(take) him to his destination.That city of the future will have no traffic jams.

    To link up the{#blank#}8{#/blank#}(vary) cities,vehicles driven by atomic power will pass along highways{#blank#}9{#/blank#}(divide) into two main groups of lanes.Each group will consist of several lanes.Some for slow traffic,some for fast.Crossroads will not exist on these highways,but will be replaced by bridges and junctions.Where these highways enter cities{#blank#}10{#/blank#} (port) and other built-up areas,they will pass through underground tunnels.

    Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know)as the leader of the research group that 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 thinks 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.

    For you, the "Clear and Bright" day that falls in every April might be no more than just another holiday — the fact that it comes with three days off school matters to most students {#blank#}1{#/blank#} more than the fact that it is part of the 24 solar terms.

But the UNESCO has recognized the importance of the 24 solar terms. This ancient system that Chinese people have used to keep track of the time of year {#blank#}2{#/blank#} (add) to the UNESCO list of Intangible Cultural Heritage of Humanity on Nov 30.

For starters, you may have heard your mom say: "The sanfu days are almost over. The heat won't be here for long." The sanfu days are a period of time that {#blank#}3{#/blank#} (fall) in summer, somewhere {#blank#}4{#/blank#} Minor Heat (in July) and Autumn Equinox (in September). The coldest days, or the sanjiu days, are similar. They cover the 27 days {#blank#}5{#/blank#} (follow) Winter Solstice.

    In some places, solar terms guide people's lives through special foods, {#blank#}6{#/blank#} (culture) events and healthy living tips. For example, people from northern China are in the habit of eating dumplings on the day of Winter Solstice. And on Start of Autumn, some people treat {#blank#}7{#/blank#} to a big feast, especially of meat, something they call "putting on autumn weight", or tieqiubiao.

    But no matter {#blank#}8{#/blank#} differently people celebrate the 24 solar terms, they have been here for a long time and could last forever.

    According to Chinese writer and academic Yu Shicun, unlike many other examples of intangible cultural heritage – Peking Opera and Chinese Zhusuan, for example – the solar terms are neither regional (地域的) nor a type of art or skill. Instead, the system is a philosophy of time, {#blank#}9{#/blank#} applies to everything. And this means they are {#blank#}10{#/blank#} (likely) to die out.
