A recent study suggested that taking a bottle of water into the exam hall could help students improve their grades.

    According to the study those who brought drinks,{#blank#}1{#/blank#}(especial) water, with them when sitting their exams performed up to 10 percent better than those who did not.

    Comparing their exam results with their normal schoolwork grades, scientists then found that all those who {#blank#}2{#/blank#}(bring) drinks with them got better grades {#blank#}3{#/blank#} between 2 and 10 percent.

    It is unclear {#blank#}4{#/blank#} drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a {#blank#}5{#/blank#}（help）effect on our brains. Drinking water may also cut {#blank#}6{#/blank#}on anxiety,{#blank#}7{#/blank#} has a bad effect on exam performances.

    Whatever the explanation, it is obvious that students should try hard to keep enough water in their bodies during exams. So next time,{#blank#}8{#/blank#} you are going to have a big exam, try {#blank#}9{#/blank#} (bring) a bottle of water with you. Who knows — it {#blank#}10{#/blank#} help you pass the exam!

Gift from A Stranger

My local supermarket is always busy. The first parking space I found was convenient. but I'd noticed a woman in a blue car circling for a while. {#blank#}1{#/blank#}I was in a good mood, I let her have it. On the edge of the car park I backed into the next available spot——it was a tight fit. Pretty soon I'd made my way through the supermarket and was back in the flesh air. {#blank#}2{#/blank#}(feel)good, I emptied my purse change into the hands of a homeless man and{#blank#}3{#/blank#}(help)a struggling woman reverse park.

    Just as I approached my car, I saw the woman I'd let have my car spot earlier. She was giving me {#blank#}4{#/blank#}odd look——half intent(热切的), half puzzled. I smiled and wished her a pleasant day. As I squeezed back into my car, I saw the same lady{#blank#}5{#/blank#}(look)in at me. "Hello, "she said, hesitantly. "This {#blank#}6{#/blank#}sound crazy but I was on my way to drop some of my mother's things off at the charity bins. You are just so much {#blank#}7{#/blank#}her. You helped those people, I noticed, and you seemed so happy. "She looked at me{#blank#}8{#/blank#}(meaning)and passed a box in through the window. "I think she would like you to have it. "{#blank#}9{#/blank#}(shock), I took it from her automatically. She smiled and walked away.

    After a pause. I opened the box. Inside was a beautiful gold necklace with a large grey pearl. It was the {#blank#}10{#/blank#}(nice)gift I'd ever received, and it was from a complete stranger. The necklace was around my neck, a warm reminder of human kindness.

    After Donald Trump became the 45th American president, a new video of his granddaughter Arabella {#blank#}1{#/blank#} (go) popular once again on the Internet. In this video, the little girl wore a qipao, a kind of {#blank#}2{#/blank#} (tradition) Chinese dress. She stood in front of a table to recite ancient Chinese poems. These poems are familiar {#blank#}3{#/blank#} most Chinese people and they are often recited by Chinese kids. Arabella made the video to remember Chinese Monkey Year, {#blank#}4{#/blank#} ended on January 27th, 2017.

    Arabella's family are {#blank#}5{#/blank#} (interest) in Chinese culture. They can even make Chinese dumplings and sing Chinese songs. Arabella began to study Chinese {#blank#}6{#/blank#} she was 18 months old. Now she can speak Chinese {#blank#}7{#/blank#} (fluent). Early in February, 2016, 4-year-old Arabella recited a Tang Dynasty poem in Chinese. {#blank#}8{#/blank#} (she) mother sent her video online and won lots of “likes” from all over the world.

    On Sonia Weibo, many users thought Arabella was a wonderful and surprising girl. “I'm glad {#blank#}9{#/blank#} (see) the little angel loves Chinese culture,” wrote a user called “orange”.

    “At least the video shows that Trump is serious about {#blank#}10{#/blank#} (educate) and never closes the door to foreign culture,” said another user named “stAU79”.

    Senior citizens are the first to come to our mind when you think of hearing loss, but in a recent report, hearing professionals worry teenagers will soon outnumber aging adults {#blank#}1{#/blank#} it comes to living with hearing loss.

    The rise in popularity of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most, teenagers! A research {#blank#}2{#/blank#} (conduct) by the World Health Organization finds that nearly 50% of teens {#blank#}3{#/blank#} (fall) into the habit of exposing themselves to unsafe levels of sound so far.

    A sound is considered unsafe when it goes beyond 85 decibels (分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the {#blank#}4{#/blank#} (little) time it takes to cause damage. Because hearing loss is {#blank#}5{#/blank#} (typical) considered a health problem for the elderly, it is difficult to convince already stubborn teenagers that they really are doing damage {#blank#}6{#/blank#} their ears.

    Young adults {#blank#}7{#/blank#} have been exposed to loud noise over a period of time may have some hearing loss symptoms. Their {#blank#}8{#/blank#} (able) to learn is compromised, and they may have difficulty developing social skills.

    In an effort to help teens better protect their hearing, we suggest {#blank#}9{#/blank#} (set) volume limits on personal audio devices. {#blank#}10{#/blank#} is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears a rest.
