Over the years I've been teaching kids about a simple but powerful concept—the ant philosophy, an{#blank#}1{#/blank#} (amaze) four-part philosophy.

    First, ants never quit. If they're heading somewhere and you try to stop them, they'll climb over. they'll climb under, or they'll climb around. They never give up{#blank#}2{#/blank#} (look) for a way to get where they{#blank#}3{#/blank#} (suppose) to go! Second, ants think about winter and summer. They are always gathering in their winter food in the middle of summer and they are making{#blank#}4{#/blank#}. (prepare) for the long cold winter. So you have to think about storms in summer; think about rocks{#blank#}5{#/blank#} you enjoy the sand and sun. Third, ants think about summer all winter. During the winter, they remind{#blank#}6{#/blank#} (they), "This won't last long and we'll soon be out of here. " On {#blank#}7{#/blank#}．first warm day, the ants are out. If it{#blank#}8{#/blank#} (turn) cold again, they'll dive back down. But they come out again if it is warm Last, how much will an ant gather during the summer to prepare for the winter? All that it{#blank#}9{#/blank#} (possible) can. {#blank#}10{#/blank#} you can learn from the ant philosophy is: Never give up, look ahead, stay positive and do all you can.

    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.

    Every year, butterfly(蝴蝶) lovers in California go out in November to count monarch butterflies. They {#blank#}1{#/blank#}(get) a worrying result from their fall monarch count in 2018—{#blank#}2{#/blank#} number of monarchs had dropped by 86% since 2017.

The orange and black monarch butterflies are famous {#blank#}3{#/blank#} their long migrations(迁徙)—they fly thousands of miles every year. In the spring and summer they fly north; in the fall they fly south again.

    Monarchs, like most butterflies, are {#blank#}4{#/blank#}(terrible) important for plants. They help create more plants by spreading pollen(花粉) between plants. In turn, monarchs depend on plants for food. And they depend completely on a plant called milkweed {#blank#}5{#/blank#}(lay) their eggs.

    But monarchs have been facing growing problems for years. As more and more wild land has been turned into large farms, the monarchs have had trouble {#blank#}6{#/blank#}(find) enough milkweed. Many farms also use chemicals {#blank#}7{#/blank#} will kill insects in order to protect their plants. These chemicals also affect monarchs. Besides, pollution has made milkweed less {#blank#}8{#/blank#}(health) for the monarchs than it used to be.

    Scientists say monarchs will be in danger of dying out in the next 20 years if nothing {#blank#}9{#/blank#}(do) to save them.

   {#blank#}10{#/blank#}(thing) that people can do to help include planting milkweed, controlling the use of chemicals, protecting wild areas, and planting trees.
