Mary will never forget the first time she saw him. He suddenly appeared in the class one day, {#blank#}1{#/blank#}(wear)sun glasses. He walked in as if he {#blank#}2{#/blank#}(buy) the school. And the word quickly got around that he was from New York City.

For some reason he sat beside Mary. Mary felt {#blank#}3{#/blank#}(please), because there were manyempty seats in the room. But she quickly realized that it wasn't her, it wasprobably the fact that she sat in{#blank#}4{#/blank#} last row.

{#blank#}5{#/blank#}he thought hecould escape attention by sitting at the back, he was wrong. It might have madeit a little {#blank#}6{#/blank#}(hard) foreverybody because it meant they had to turn around, but that didn't stop thekids in the class. Of course whenever they turned to look at him, they had tolook at Mary,{#blank#}7{#/blank#} made her feel like a star.

“Do you need those glasses for medical reasons?” the teacher asked. The new boy {#blank#}8{#/blank#}(shake) his head. “Then I'd appreciate {#blank#}9{#/blank#} if you didn't wear them in the class. I liketo look your eyes when I'm speaking to you.” The new boy looked at the teacherfor a few seconds and all the other students wondered {#blank#}10{#/blank#} the boy would do. Then he took them off, gavea big smile and said, “That is cool.”

    Mr. James owns a company. He put an advertisement {#blank#}1{#/blank#}a newspaper for a boy to work in his office. Out of nearly fifty people {#blank#}2{#/blank#}came to apply, the man selected one and dismissed {#blank#}3{#/blank#}others.

    “I would like to know,” said a friend, “the reason you preferred that boy, who brought neither a single letter, {#blank#}4{#/blank#}a single recommendation.”

    “You are wrong,” said the gentlemen. “He had many. He wiped his feet at the door and closed the door behind him, {#blank#}5{#/blank#}(mean) that he was careful. He gave his seat immediately to an old man, showing that he was kind and {#blank#}6{#/blank#}(thought). He took off his cap when he came in and answered my questions quickly, showing that he was a polite gentleman. Everyone else stepped over the book that I {#blank#}7{#/blank#}(put) on the floor purposely. He picked {#blank#}8{#/blank#}up and placed it on the table, and he waited quietly for his turn instead of pushing and crowding. When I talked to him, I {#blank#}9{#/blank#}(notice) his tidy clothing, his neatly brushed hair, and his clean finger mails. Can't you see that these are excellent recommendations? I considered them to be more significant than {#blank#}10{#/blank#}(letter).”

    Hearing the words, the friend nodded in agreement.

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.

    Since July 2019, China's online food-delivery platform Eleme {#blank#}1{#/blank#} (carry) out a new service of picking up garbage from its users in Shanghai.

    The service comes after {#blank#}2{#/blank#} recently-released regulation on waste management in Shanghai. Individuals {#blank#}3{#/blank#} throw away their garbage without being sorted out can be fined up to 200 yuan, while companies and {#blank#}4{#/blank#} (organize) can face fines up to 50,000 yuan.

    The trash takeaway service requires residents to sort {#blank#}5{#/blank#} (they) own garbage before it {#blank#}6{#/blank#} (pick) up by workers from Eleme, who will ensure the waste is disposed of in the correct garbage bins.

    It's obvious that this service is {#blank#}7{#/blank#} (convenience) to the old, especially to the disabled customers. {#blank#}8{#/blank#}, many netizens on Sina Weibo don't think Eleme is providing a wonderful service, saying it just wants {#blank#}9{#/blank#} (make) money. They think 12 yuan for an order is too much. Besides, many more people doubt if these collectors will wash their hands after dealing {#blank#}10{#/blank#} the trash.

Body language is one of {#blank#}1{#/blank#} most powerful means of communication, often even more powerful than {#blank#}2{#/blank#}(speak) language. People around the world show all kinds of feelings, wishes and attitudes that they might never speak aloud. {#blank#}3{#/blank#} is possible to "read" others around us, even {#blank#}4{#/blank#}they do not want us {#blank#}5{#/blank#}(catch) their unspoken communication. Of course, body language can be misread, but many{#blank#}6{#/blank#}(gesture) and actions are universal. The most universal {#blank#}7{#/blank#}(face) expression is, of course, the smile—its function is to show happiness and put people {#blank#}8{#/blank#} ease. It does not always mean that we are {#blank#}9{#/blank#}(true) happy, however. Smiles around the world can be false, hiding other feelings like anger, fear or worry. There {#blank#}10{#/blank#}(be) unhappy smiles, such as when someone "loses face" and smiles to hide it. However, the general purpose of smiling is to show good feelings.
