A motto is a sentence or a phrase which can inspire us especially when we are {#blank#}1{#/blank#} (face) with difficulties. Many of us use well-know {#blank#}2{#/blank#} (say) as mottos, such as “Where there is a will, there is a way.” Or “nothing is difficult if you put your heat into it.”, and so on. My motto is “God helps those who help{#blank#}3{#/blank#} Sometimes I am lazy {#blank#}4{#/blank#} don't want to make efforts to work hard, but the moment I think of my motto I will get{#blank#}5{#/blank#}(energy) again and devote myself to what I am doing. I write my motto {#blank#}6{#/blank#} I can see it easily. Every time I fail in my exam and begin to lose heart, the sight of my motto inspires me {#blank#}7{#/blank#} much confidence. My motto also makes me become an {#blank#}8{#/blank#} (dependent) person. That is to say, I won't rely on others {#blank#}9{#/blank#} (easy). My friends, what is your motto? If you still haven't got a motto, please choose {#blank#}10{#/blank#} because a motto can have a great effect on you.

    A young man wanted to find a job after{#blank#}1{#/blank#}(finish) school. One day he came to a big company for it. There were six young people that day{#blank#}2{#/blank#}the Company only wanted one. The interview was very easy. It was only a five{#blank#}3{#/blank#}(minute) short talk. Then the six young People all went home.

    {#blank#}4{#/blank#}the morning of the third day, the young man got a text message. It{#blank#}5{#/blank#}(say). We are sorry to tell you that you cannot work in our company."

    The young man felt very sad, but he answered{#blank#}6{#/blank#}(polite)"Thank you all the same."{#blank#}7{#/blank#}(late)that afternoon, the young man got another text message saying "We are glad{#blank#}8{#/blank#}(tell)you that you can be one of us!”

    The young man didn't know why. People in the company told him, "That's because of{#blank#}9{#/blank#} same message in the morning. Only you said “Thank you". That was the real test, and only you gave the right answer."

    When you feel{#blank#}10{#/blank#}(disappoint), do not forget to say "thank you" to the one who disappoints you.

Meet Alexa, Your Digital Roommate

    Who is Alexa? She is a digital assistant that is part of the voice-activated Echo Dot "smart speaker" produced by Amazon. This year Saint Louis University in Missouri has placed one of the speakers in every dorm room {#blank#}1{#/blank#} its campus. Students can ask the virtual assistant anything from "When are the football teams playing?" to "What's the square root of 1440?"

    SLU student Brendan McGuire said: "Instead of searching on the Internet while I {#blank#}2{#/blank#} (tap) away at my computer, I can just ask Alexa: Hey Alexa, ask SLU what's the molecular(分子的)weight of water? And I can have the answer without {#blank#}3{#/blank#}(interrupt) my process." That's exactly {#blank#}4{#/blank#} school officials had in mind when they decided to provide the smart speakers free of charge for students.

    "The students we attract {#blank#}5{#/blank#} (drive) to achieve success in and out of the classroom," David Hakanson, SLU's vice president, said. "Every minute we can save our students from having to search for the information online is another minute {#blank#}6{#/blank#} (commit) to their education."

    Saint Louis University is the first in the U.S. {#blank#}7{#/blank#} (include) an Echo Dot smart speaker in every campus living space. Other colleges have also found ways to offer the technology to students. This year Northeastern University in Boston installed 60 speakers in public places {#blank#}8{#/blank#} students could get answers to common questions.

    At Arizona State University, engineering students living in the brand-new residence hall have the option of adding an Amazon Echo Dot to their rooms. "Our focus is putting this technology into the hands of our students in a way{#blank#}9{#/blank#} will build an ecosystem. {#blank#}10{#/blank#} supports voice technologies throughout the ASU campus," said Heredia, a director at ASU.

    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.
