    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.

    One of the biggest challenges {#blank#}1{#/blank#} (face) students today is how to concentrate on studies. Almost all of them are struggling for their concentration power. In an age {#blank#}2{#/blank#} mobile phones and Internet are eating up most of our time and energy, one can understand how different it is to focus attention and energy on studies.

    One of the most important {#blank#}3{#/blank#} (factor) for developing concentration on a task, whether it is study or anything else, {#blank#}4{#/blank#} (be) to develop an interest in that task. We are able to focus {#blank#}5{#/blank#} (easy) and more long periods of time on tasks that we find more interesting. If you ever want to concentrate on anything and studies are no {#blank#}6{#/blank#} (except), you need {#blank#}7{#/blank#}(ensure) that the environmental around you is distraction (注意力分散) free. So the question is not how to concentrate on studies {#blank#}8{#/blank#} how to avoid distractions that have swallowed up mankind today. The only way to guarantee {#blank#}9{#/blank#} distraction free environment is by getting rid of all the unnecessary things around you, including the electronic gadgets (小器具) {#blank#}10{#/blank#} mobile phones.

    Diets have changed in China — and so too has its top crop. Since 2011, the country {#blank#}1{#/blank#}(grow) more corn than rice. Corn production has jumped nearly 125 percent over {#blank#}2{#/blank#} past 25 years, while rice has increased only 7 percent.

    A taste for meat is {#blank#}3{#/blank#} (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice {#blank#}4{#/blank#} (improve) water quality. Corn uses less water {#blank#}5{#/blank#} rice and creates less fertilizer(化肥) runoff. This switch has decreased {#blank#}6{#/blank#} (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

    According to the World Bank, China accounts for about 30 percent of total {#blank#}7{#/blank#} (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government {#blank#}8{#/blank#} (start) a soil-testing program {#blank#}9{#/blank#} gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while {#blank#}10{#/blank#} (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.
