Spending more than an hour on your smart phone each day may be a sign that you are suffering from depression,{#blank#}1{#/blank#}new study has suggested. The more time is spent {#blank#}2{#/blank#} (use) a phone for any reason including texting and going online, the more likely volunteers were{#blank#}3{#/blank#}have the blues.

    Monitoring people's comings and{#blank#}4{#/blank#}(go) using GPS tracking on their phones also helped track mood. Spending most of your time at home was also {#blank#}5{#/blank#} (link) to depression, as was having an/a{#blank#}6{#/blank#} (regular) daily schedule, such as unusual shift patterns. “{#blank#}7{#/blank#}people are depressed, they tend to withdraw and don't have the motivation and energy to go out and do things,” said senior author David Mohr. “The data {#blank#}8{#/blank#}showed depressed people tended not to go many places{#blank#}9{#/blank#} (reflect) the loss of motivation seen in depression.”

    “The significance of this is that we can detect if a person has depressive symptoms and the severity of those symptoms{#blank#}10{#/blank#}asking them any questions. Phones can provide data obviously and with no effort on the part of the users.”

    This summer I travelled from noisy Beijing to Wuzhen, a beautiful village in Zhejiang Province. Unfolded before me was{#blank#}1{#/blank#}unique image of this water country—the stone bridge and the water flowing, all like fairy tales to me.

    However{#blank#}2{#/blank#} impressed me most was not the natural scenery but the scene of a grandma bathing a little baby in a wooden basin with the door open. My friends couldn't help{#blank#}3{#/blank#}(take) pictures of them. To my surprise, the grandma smiled and waved at us. All of a sudden, my heart was filled with {#blank#}4{#/blank#} (warm).

    I shared the photo and my{#blank#}5{#/blank#} (forget) experience with my friends. They were {#blank#}6{#/blank#}(simple) moved as I was, but at the same time they reminded me of the unpleasant experiences in big cities. We feel embarrassed to see people quarreling in public because they{#blank#}7{#/blank#} (step) on accidentally by strangers.

    According to a recent survey{#blank#}8{#/blank#} (make) in November 2016: 45 percent of the residents don't know the names of their neighbors; 63 percent have never devoted{#blank#}9{#/blank#} (they) to talking to their neighbors; 67 percent think that the relationship between them and their neighbors is just so-so, or even bad.

    Wouldn't it be beautiful to say hello to our neighbors who just came back {#blank#}10{#/blank#}work give them a smile?

You Are a Time Traveler

    Time travel has long fascinated people. Traveling to the past or future would allow you to live in exciting periods of history or get a glimpse(一瞥) of {#blank#}1{#/blank#} the future holds. Think about it. If you could travel in time, where would you go? Perhaps you would voyage far ahead of the present day {#blank#}2{#/blank#} (meet)your future self! What about watching an original performance of {#blank#}3{#/blank#} Shakespeare play in Elizabethan England? Or maybe you would pay a visit to {#blank#}4{#/blank#} (you)as a baby.

    Since these ideas are universally appealing to everyone, it is {#blank#}5{#/blank#} (nature)that time travel interests so many writers, filmmakers, and scientists. It has been depicted in a {#blank#}6{#/blank#} (various) of media, such as literature, film, and science reports. But you might be surprised to realize that {#blank#}7{#/blank#} the smallest sense of the term, we are all time travelers. Even as you sit here {#blank#}8{#/blank#} (read)this article, time is racing forward. The future becomes the past as soon as it happens. The present is so fleeting(稍纵即近)! Everything you do quickly {#blank#}9{#/blank#} (become) part of the past, and so it is that we move through time. The famous scientist Albert Einstein, assigned a mathematical formula to this idea, {#blank#}10{#/blank#} is called The Theory of Relativity.

    I want to introduce my class to you. My class {#blank#}1{#/blank#} (be) very small and there {#blank#}2{#/blank#} (be) only 20 students in it. Some {#blank#}3{#/blank#} (be) boys and the others {#blank#}4{#/blank#} (be) girls. All of us {#blank#}5{#/blank#} (be) getting along well with each other. None of us {#blank#}6{#/blank#} (have) quarrelled with each other. Every boy and every girl {#blank#}7{#/blank#} (help) the others in every subject, so nobody {#blank#}8{#/blank#} (fail) in any exam. Our headmaster often {#blank#}9{#/blank#} (praise) us for our helping each other. Every weekend, there {#blank#}10{#/blank#} (be) a meeting and our headmaster, with five of us, {#blank#}11{#/blank#} (attend) it, discussing how to make our class better.

    Such {#blank#}12{#/blank#} (be) our class, a happy and friendly family.
