—No, it's so {#blank#}1{#/blank#} that I cannot even get close to it.

    The earth was just {#blank#}1{#/blank#} cloud of dust after the “Big Bang”. The earth exploded {#blank#}2{#/blank#}(loud) with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were {#blank#}3{#/blank#}(make) the earth's atmosphere. As the earth cooled down, water began to appear on its surface. It allowed the earth to dissolve {#blank#}4{#/blank#}(harm) gases. Then life began to develop.

    Small plants multiplied and filled the oceans and seas with oxygen. This encouraged the {#blank#}5{#/blank#}(develop) of early shellfish and fish. Land animals such as insects, reptiles and dinosaurs {#blank#}6{#/blank#}(appear) after green plants came into being. Small clever animals spread all {#blank#}7{#/blank#} the earth. They are putting too much carbon dioxide into the atmosphere, {#blank#}8{#/blank#} prevents heat from escaping from the earth into space. {#blank#}9{#/blank#} life will continue on the earth for millions of years to come will depend on whether this problem can {#blank#}10{#/blank#}(solve).

    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.
