“USA? Britain? Which country is{#blank#}1{#/blank#}(good) to study in?” We often hear such discussion. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world.

    It's true that studying abroad can help students develop{#blank#}2{#/blank#}(they). Their foreign language skills will{#blank#}3{#/blank#} (improve) and it may be easier to find jobs.

    But there are problems{#blank#}4{#/blank#} should be considered. Language is the first. Students must spend a lot of time{#blank#}5{#/blank#} (learn) another language.

    Students must also learn{#blank#}6{#/blank#} (live) without parents' care and deal with all kinds of things they didn't have to do before, like looking after themselves. There are {#blank#}7{#/blank#} (report) about Chinese students abroad running into an ocean of difficulties{#blank#}8{#/blank#} giving up in the end. When they have to take care {#blank#}9{#/blank#} themselves, it is hard for students to study well.

    Finally, studying abroad brings a heavy burden to the family. For most Chinese parents, the cost of studying abroad{#blank#}10{#/blank#} (be) very high. But is it worth it?

    Many people agree that going to a museum is a good way of learning about ancient treasures. However, others may find {#blank#}1{#/blank#} boring to spend hours there. Therefore, how to make museums and their lifeless collections more appealing is a tough question worth {#blank#}2{#/blank#}（attach）importance to.

    Luckily, National Treasure（国家宝藏）, a TV program which{#blank#}3{#/blank#}（begin）to air on Dec, 3, 2017, shed light on ways to inspire interest in museums and their collections.

    Aiming to make ancient relics to come {#blank#}4{#/blank#}（live）, the program presents treasures through different artistic{#blank#}5{#/blank#}.（method）including dramatic performances and storytelling, {#blank#}6{#/blank#} fully interprets the history behind each cultural relic, so that audiences can not only understand how to appreciate the beauty of cultural relics, {#blank#}7{#/blank#} also know the civilization and the spiritual core of Chinese culture. In fact, such programs that promote traditional ancient relics have become popular {#blank#}8{#/blank#} recent years. For example, a 2016 documentary featuring the Forbidden City's cultural relics and their restorers, urged lots of college students {#blank#}9{#/blank#}（apply）to work as volunteers there. It is {#blank#}10{#/blank#}（universal）accepted that National Treasure has been successful in encouraging more people to visit museums by touching their hearts.

    A good teacher is many things to many people. In my own experience, the people I respect most are the teachers {#blank#}1{#/blank#} demanded the most discipline from their students.

    I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very {#blank#}2{#/blank#} (clear) a sign over her classroom door. It was {#blank#}3{#/blank#} simple sign that said, “Laboratory-in this room the first five letters of the word was emphasized, not the last seven.” In other words, I guess, labor {#blank#}4{#/blank#} her was more important than oratory which means {#blank#}5{#/blank#} (make) speeches.

    She prepared her work very carefully and demanded us to do the same. We got lots of homework from her.{#blank#}6{#/blank#} she had broken her arm, and everybody in the class thought that maybe the homework {#blank#}7{#/blank#} (reduce), but it continued just the same. She checked our work stamping her name at the bottom of the papers to show that she had read {#blank#}8{#/blank#}.

    I think sometimes teachers who demand most are liked {#blank#}9{#/blank#}. But {#blank#}10{#/blank#} time goes by this discipline really seems to benefit the students.

    If you only got six hours' shut eye last night, there is no need {#blank#}1{#/blank#} (lose) sleep over it.

    Scientists say that though it is {#blank#}2{#/blank#} (wide) believed that we need eight hours of sleep a night, six to seven hours is the natural amount.

    Advising short-sleepers to rest easy, the US researchers say, {#blank#}3{#/blank#} (have) important implications (暗示，含义) for the idea that we need to take sleeping pills because sleep has been reduced from {#blank#}4{#/blank#} (it) natural level by the widespread use of electricity, TV, the Internet and so on.

    The lead author of a study, Ghandi, said: "There's the {#blank#}5{#/blank#} (expect) that we should all be sleeping for eight or nine hours a night, and if we took away modern technology, we would be sleeping more. But now, for the first time, we are showing that's not {#blank#}6{#/blank#} truth."

    Most of those {#blank#}7{#/blank#} were studied slept for less than seven hours a night, with the average amount just six hours and 25 minutes. This is much less than the eight hours often {#blank#}8{#/blank#} (recommend) in western societies.

    Despite this, the people studied were in good health, {#blank#}9{#/blank#} lower rates of obesity (肥胖症), better blood pressure and {#blank#}10{#/blank#} (healthy) hearts than people in industrialised societies. They were also fitter.
