I once found that helping someone could get you into a lot of trouble.

    I was in the {#blank#}1{#/blank#} (nine) grade at the time, and we were having a final test. During the test, the girl {#blank#}2{#/blank#} (sit) next to me whispered something, but I didn't understand. Finally I found that she was trying to ask me {#blank#}3{#/blank#}I had an extra pen. She showed me that {#blank#}4{#/blank#} (her) was out of ink and would not write. I happened to have an extra one, so I put it on her desk.

    Later, after the test papers had been turned in, the teacher {#blank#}5{#/blank#} (ask) me to stay in the room when all the other students were dismissed. As soon as we were alone she began to talk to me about how important it was {#blank#}6{#/blank#} (stand) on my own two {#blank#}7{#/blank#} (foot) and be responsible for my own acts. For a long time, she talked about honesty and emphasized the fact {#blank#}8{#/blank#}when people do something dishonest, they are really cheating themselves. She made me promise that I would think {#blank#}9{#/blank#} (serious) about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me {#blank#}10{#/blank#}all those things.

    Later on, I found out that she thought I had cheated on the test.

    One day, I was walking in the street when I noticed a woman {#blank#}1{#/blank#}(come) up to me with a nervous smile and said,“Sir, can you help a person out? I haven't eaten for almost two days.” I handed {#blank#}2{#/blank#}(she) a few quarters and watched her walk away.

    That area was so poor and {#blank#}3{#/blank#}(rule) by drugs and crimes. I walked to the corner and stopped by the door of the ATM machine. Then I {#blank#}4{#/blank#}(walk) inside and made sure that no one came in behind me.

    I put my card into the machine and deposited my money with a sigh of relief.60.{#blank#}5{#/blank#} I turned to leave, I saw a wallet sitting on another machine. I had a look at it. The name on the license was one I could not pronounce, but whoever he was, he was going to get into a panic over a wallet {#blank#}6{#/blank#} his identification in it being lost in this city.

    I put it in my pocket and went home. In my apartment, I checked the online phone book {#blank#}7{#/blank#}(find) out whether there was someone who matched the name on the cards in the wallet, but without luck. I picked up the bank card and had {#blank#}8{#/blank#} thought. Because I wanted to help the guy, I called his bank. But the girl over the phone said they could not give out any personal information about their clients. So I left my contact information with her and asked her to tell the {#blank#}9{#/blank#}(own) to contact me. Two days later, a very {#blank#}10{#/blank#}(thank) gentleman appeared at my office and I gave him back his wallet.

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.

I was very frightened when{#blank#}1{#/blank#}(wake) up in hospital last Thursday. I fainted in my PE class because of low blood sugar levels. Fortunately, I was rushed to hospital{#blank#}2{#/blank#}(immediate). The doctor helped me and I made a full recovery within two days. My experience proves what a bad idea{#blank#}3{#/blank#}is to try to lose weight by skipping meals. Now I know this extreme weight-loss method has serious side{#blank#}4{#/blank#}(effect). Now I also understand that being healthy and{#blank#}5{#/blank#}(energy) is more important than being slim.

From now{#blank#}6{#/blank#}, I will pay more attention to my health rather than my weight. I will eat a{#blank#}7{#/blank#}(balance) diet to make sure I have enough nutrition. Exercising regularly is also{#blank#}8{#/blank#}important part of a healthy lifestyle. My doctor tells me that it will help me concentrate better in class. So, I{#blank#}9{#/blank#}(play) sport with my friends every other day after school, {#blank#}10{#/blank#}I hope can help me get into shape.
