My name is Wang Kun. Since middle school, my sister and I {#blank#}1{#/blank#} (dream) about taking a great bike trip. After graduating {#blank#}2{#/blank#} college, we finally got the chance to do it. It was my sister, Wang Wei,{#blank#}3{#/blank#} first had the idea to cycle along the Mekong River from where it begins to where it ends. Our cousins live near the Lancang River which {#blank#}4{#/blank#}(call) the Mekong River in other countries. My sister soon got {#blank#}5{#/blank#} interested in {#blank#}6{#/blank#}(cycle) too. Then she began to organize the trip and insisted that we start from the source of the river in Qinghai province {#blank#}7{#/blank#} the air is hard to breathe. I doubted her decision but she gave me a {#blank#}8{#/blank#}(determine) look. I know her {#blank#}9{#/blank#}(good). Once she has made up her mind, nothing can change it. Finally, I gave {#blank#}10{#/blank#}to her.

    Keeping a diary in English is one of the {#blank#}1{#/blank#}(effect) ways to improve our English writing ability.

    {#blank#}2{#/blank#}(compare) with other forms of writing, it is shorter and takes less time. It can help us to develop the habit of thinking in English. If we persist in this practice, gradually we {#blank#}3{#/blank#}(learn) how to express ourselves in English. In keeping a diary in English, we certainly run up against many {#blank#}4{#/blank#}(difficult). In the first place, it often happens {#blank#}5{#/blank#} we have trouble finding and phrases to give expression to our mind. Secondly, there are many idiomatic ways of saying things in Chinese. And it is {#blank#}6{#/blank#}(extreme) hard for us to put them into English properly.

    As far as I'm concerned, my {#blank#}7{#/blank#}(recommend) is that we should always have a notebook and a Chinese-English dictionary {#blank#}8{#/blank#} easy reach. Whenever something beats {#blank#}9{#/blank#}, we can first put it down in our notebook and then consult our dictionary. We can also turn to our English teacher for help, if necessary. In {#blank#}10{#/blank#} word, I believe that it is of great use to keep a diary in English for the development of our writing skills.

    Chinese researchers have planned to build an airport in Antarctica in November. The Chinese {#blank#}1{#/blank#} (be) not very used to flying to the southernmost continent, because the country s first polar plane, the Snow Eagle 601, {#blank#}2{#/blank#} (put) into use only three years ago.

    Before the Snow Eagle 601, Chinese researchers traveled to the ice-covered land by ship, which took significantly {#blank#}3{#/blank#} (long) than flying. There are currently more than 20 airports in Antarctica, but none of them belong to China. The Snow Eagle 601 has to rely on Russian airports {#blank#}4{#/blank#} (take) off and land. That's {#blank#}5{#/blank#} the Chinese researchers decided to build their own. Building an airport in Antarctica is very different from building one elsewhere. The continent is covered by a {#blank#}6{#/blank#} (constant) moving layer of ice, so the builders must find somewhere that moves at the slowest possible pace and in a {#blank#}7{#/blank#} (fix) direction.

    The builders managed to find a spot back in early 2017 following {#blank#}8{#/blank#} tough measuring process that took place in the storm-like polar winds. The next problem is the snow. The soft nature of snow makes {#blank#}9{#/blank#} a bad material for a runway. So the builders must use road roller-like {#blank#}10{#/blank#} (machine) to press the snow, which can be very time-consuming in extreme coldness.
