China has once again proved its{#blank#}1{#/blank#} (able)to change the world with the“new four great inventions”：high-speed railways，electronic payments，shared bicycles and online shopping．

    They're related to China's high-tech innovation(创新){#blank#}2{#/blank#} has improved the quality of people's lives，according to a survey{#blank#}3{#/blank#} (make)by the Belt and Road Research Institute of Beijing Foreign Studies University．

    A good teacher is many things to many people. In my own experience, the people I respect most are the teachers {#blank#}1{#/blank#} demanded the most discipline from their students.

    I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very {#blank#}2{#/blank#} (clear) a sign over her classroom door. It was {#blank#}3{#/blank#} simple sign that said, “Laboratory-in this room the first five letters of the word was emphasized, not the last seven.” In other words, I guess, labor {#blank#}4{#/blank#} her was more important than oratory which means {#blank#}5{#/blank#} (make) speeches.

    She prepared her work very carefully and demanded us to do the same. We got lots of homework from her.{#blank#}6{#/blank#} she had broken her arm, and everybody in the class thought that maybe the homework {#blank#}7{#/blank#} (reduce), but it continued just the same. She checked our work stamping her name at the bottom of the papers to show that she had read {#blank#}8{#/blank#}.

    I think sometimes teachers who demand most are liked {#blank#}9{#/blank#}. But {#blank#}10{#/blank#} time goes by this discipline really seems to benefit the students.

    That Beijing, together with Zhangjiakou, succeeded in getting the chance to host the 2022 Winter Olympic Games, speeds up the development of Zhangjiakou City. Word came{#blank#}1{#/blank#}the Beijing-Zhangjiakou high-speed railway,{#blank#}2{#/blank#}(locate) in North China, is currently under construction, and{#blank#}3{#/blank#}(expect) to be completed by 2020 in preparation for the cities to host the 2022 Winter Olympics. Starting from Beijing North Railway Station, heading west through the Great Wall three times in the capital's territory, the project is a big challenge,{#blank#}4{#/blank#}designers say the explosions needed to dig the tunnels will not have an impact on the structure. The line has a{#blank#}5{#/blank#}(long) of 174 km as a double tracked passenger dedicated line, with ten stations situated along its route.
