    刘璠字宝义，沛国沛人也。璠九岁而孤，居丧合礼。少好读书，兼善文笔。

    年十七，为上黄侯萧晔所器重。范阳张绾，梁之外戚，才高口辩，见推于世。璠年少未仕，而负才使气，不为之屈。绾尝于新渝侯坐，因酒后诟京兆杜骞曰：“寒士不逊。”璠厉色曰：“此坐谁非寒士？”璠本意在绾，而晔以为属己，辞色不平。璠曰：“何王之门不可曳长裾也！”遂拂衣而去。晔辞谢之，乃止。后随晔在淮南璠母在建康遘疾璠弗之知尝忽一日举身楚痛寻而家信至云其母病璠即号泣戒道绝而又苏。当身痛之辰，即母死之日也。居丧毁瘠，遂感风气。服阕后一年，犹杖而后起，及晔终于毗陵，故吏多分散，璠独奉晔丧还都，坟成乃退。梁简文时在东宫，遇晔素重，诸不送者皆被劾责，唯璠独被优赏。解褐王国常侍，非其好也。

    璠少慷慨，好功名，志欲立事边城，不乐随牒平进。时寇难繁兴，未有所定。还至白马西，属达奚武军已至南郑，璠不得入城，遂降于武。太祖素闻其名，先诫武曰：“勿使刘璠死也。”故武先令璠赴阙。璠至，太祖见之如旧。谓仆射申徽曰：“刘璠佳士，古人何以过之。”徽曰：“昔晋主灭吴，利在二陆。明公今平梁汉，得一刘璠也。”时南郑尚拒守未下，达奚武请屠之，太祖将许焉，唯令全璠一家而已。璠乃请之于朝，太祖怒而不许。璠泣而固请，移时不退。柳仲礼侍侧曰：“此烈士也。”太祖曰：“事人当如此。”遂许之。城竟获全，璠之力也。

    世宗初，授内史中大夫。寻封平阳县子，邑九百户。在职清白简亮，不合于时，左迁同和郡守。璠善于抚御，莅职未期年，生羌降附者五百余家。前后郡守多经营以致赀产，唯璠秋毫无所取，妻子并随羌俗，食麦衣皮，始终不改。洮阳、洪和二郡羌民，常越境诣璠讼理焉。其德化为他界所归仰如此。天和三年卒，时年五十九。

    Are you suffering from FOMO—that is, Fear Of Missing Out? Research shows that a growing number of young people are, with worrying consequences for their sleep and schoolwork.

    ____You aren't able to do your best unless you sleep well. Most experts agree that the optimum(最适宜) number of hours is eight, and this has been accepted as common sense for as long as I can remember. However, I was young once and know most of you get much less sleep than that.

    I read an interesting article in a teachers' magazine recently.____Worryingly, the results showed that teenagers are facing a new problem. They may go to bed and get up at appropriate times, but a growing number are waking up in the middle of the night, not to use the bathroom or have a snack, but because of FOMO.

    According to the article, the number of students waking up during the night to check social media is growing. Afraid of missing a comment or opportunity to take part in a chat, teenagers are waking at all times of the night, going online and getting involved.____

    Experts are worried about this growing trend and the report reveals some worrying statistics: 23% of 12-to 15-year-olds wake up nearly every night to use social media.____One in third of the students are constantly tired and unable to function to their full capacity.

    So I'd like to ask you to be responsible when it comes to social media. Switch off your devices at night. The world won't end and your social media will be waiting to greet you in the morning!____

A.But things are getting out of hand.

B.They did a study of 848 students in Wales.

C.Another 15% wake up at night once a week for the same reason.

D.I give you my word that you won't have missed anything important.

E.All happens when they should be sound asleep.

F.FOMO is the fear that everyone else is having more fun and more excitement than you.

G.Everybody knows how important it is for students to get a good night's sleep every night.
