Looking good can matter a lot when you are a teenager. Of course the budget(财政） matters a lot, too. Luckily, fashion trends (流行趋势) in the UK mean that getting the right image doesn't have to cost the earth. Here's a quick guide to which looks are hot this year.

    For girls, the 70s are back. Wide-legged jeans, platform shoes and skirts that reach the feet are again in fashion among UK teens, topped off with colored, shining eyeshadow. Girls can have fun mixing and matching bright shades. Colors like pink, orange and light yellow-green are all perfectly fit. Shorts and mini-skirts are still popular in cold weather. By wearing a pair of tights underneath ( 在..底下), girls can stay warm as well as fashionable in the winter.

    How about boys? To look lively, fans of skateboards and snowboards can dress in skinny jeans accompanied by a T-shirt topped off with a baseball cap or a woolen hat. Music is often an inspiration for fashion, and hip-hop music fans like to dress in baggy jeans, T-shirts, baseball caps and sneakers. For those who can afford it, designer clothing is a must, especially if the logo is showing.

阅读下面的文字，完成各题。

材科一：

突如其来的新冠疫情给我国经济带来巨大压力，据不完全统计，极至5月31日，全国确诊住院患者结算人数5.8万人次，总医疗费用13.5亿元，全国各级财政安排的防控资金达到1169亿元，用于困难群众基本生活保障的资金为1030亿元，再加上各行各业在停工停产期间的损失，已经超过1万亿元。一季度，我国GDP为206504亿元，比上年同期下降6.8%，其降幅创多年之最。由于疫情对经济的冲击，消费者对企业经营利润、就业形势和收入增长预期的悲观可能导致消费者(特别是中老年人)信心不足，从而降低支出和增加预防性储蓄。预期消费的下降对于经济复苏和提振显然有不利影响。

材料三：

1999年，泡沫经济破裂后，日本政府为提振经济刺激消费开始在地方政府层面发放名为“地城振兴券”的消费券。这笔资金由日本中央政府提供，发放对象和金额为家中有15岁以下儿童的家庭每位儿童可领2万日元券，65岁以上的不缴纳住民税的老人每人可领取2万日元券。该消费券可以在大多数超市、小商铺、酒店使用。明确禁止使用的范围是偿还银行贷款、购买股票、缴纳水费电费煤气费等公共费用、缴纳税金等。据日本政府无当年8月公布的《地域振兴券激励消费效果》报告，此次消费券带动新增消费2025亿元，占被使用消费券总额约32%，占当时日本全国 GDP的0.04%，以及全国个人消费比重的0.1%。2009年受国际金融危机影响，日本再次出台提振消费举措，这次选择了向全体国民直接发放现金的方式，每人发放1.2万日元，18岁以下和65岁以上则是每人2万日元。这次发放现金所带动的新增消费与发放消费券几乎一样为其总额的32%左右。本次疫情冲击下，日本先是宣布将为低收入家庭每家发放30万日元现金，后来又撤回了该政策，改为全体国人每人发放10万日元。

材料四：

如此大规模使用消费券提振经济在我国尚属首次。从已经发放消费券省市的实践看，其之所以能够取得很好成效，得益于各地在发放消费券时注重科学施策，特别是做到了精准发放。这主要体现在两个方面：一是借助电子支付平台发放，既节约成本，缩短链条，又保证了可追溯，兼顾便捷与公平公正；二是划定使用领城和使用时间，更好地与需求匹配。

当然，消费券对市场的刺激固然速效，但作用毕竟有限。有些行业市场在短期刺激下相对容易被激活，但有些市场则不是通过消费券就可以简单撬动的。特别需要强调的是，真正发挥消费券提振消费、拉动经济的作用，要掌握好度。一方面，发放消费券需考虑财政承受能力，避免过度透支；一方面，要抓好消费券发放和使用监管，避免职业“蒋羊毛”、刷单、黄牛等违反市场秩序的行为，保证“券”尽其用。在具体执行时，我们建议采取“双层”消费刺激方案。首先针对低收入群体和因疫情失业的群体发放1000元用于消费的现金券，对湖北省就业人口和因疫情失业人口全员发放消费券。其次，在全国范围内大规模发放核销额为5000亿元的消费券，由国家统筹，可以让地方政府根据本地情况探索“一城一策”。

They were wagging  in the river, looking lovely. I sat on the weeds   and made some adjustment to my framework.

    昆明的天，非常非常的蓝。

    这是一种不可名状的蓝，只要有一小块这样的颜色，就会令人赞叹不已了。而天空是无边无际的，好像九天之外，也是这样蓝着。蓝得丰富，蓝得慷慨，蓝得澄漱而光亮，蓝得让人每抬头看一眼，都要惊一下，哦！有这样蓝的天！

    一九三八年九月二十八日日寇飞机首次袭击昆明，玷污了纯净的蓝天和瑰丽的白云。

    空袭威胁着昆明。跑警报已经成为昆明人生活的一项重要内容，像吃饭睡觉一样占一定的时间。有一阵空袭格外频繁，人们早早起身，烧好一天饭食，不等放警报便出城去，到黄昏才回家。有一阵空袭稍稀，人们醒来后最先想到的还是今天会不会有警报。如果有几天没有，人们会在菜市上说点废话：“日本鬼子轰炸没有后劲，飞机给打下来了。”“几架？”“十多架。”“我听说二十多架！”说完这些无可追究的话，哈哈一笑走散。

    日本空军大概在养精蓄锐。让昆明人享受了几天平安之后，又一次大举轰炸了昆明。  随着警报声响，明仑大学的师生都向郊外走去。他们都可谓训练有素了，不少人提着马扎，到城外好继续上课。一个小山头两边坡上，很快成为两个课堂，一边是历史系孟樾（字弗之）讲授宋史，一边是数学系梁明时讲授数论。孟樾讲到周濂溪的太极图说。梁明时讲到第一位对数论做出巨大贡献的欧洲人费马。“现在说到无限下推法：形如4n+1的一个质数可能而且只能以一种方式表达为两个平方数之和……”这些玄妙的话传入历史系学生的耳鼓。数学系学生则听见“太极图说‘惟人也得其秀而最灵。形既生矣，神发知矣，五性感动而善恶分，万事出矣’”。两位先生有力的声音碰撞着，大家听得都笑起来。

    紧急警报响了，讲课依然进行，没有人移动。传来了飞机的隆隆声，仍然没有人移动。空中出现了轰炸机，排成两个正方形，黑压压的，向头顶飞来。愈来愈强的马达声淹没了讲课的声音。两位先生同时停止了，示意学生隐蔽。

    “升空了，我们的飞机升空了！”学生们兴奋地大喊。只见我们的飞机只有两架，正勇敢地升空迎战。下面高射炮也开始射击，但究竟火力太小，敌机仍然从容地飞，开始按着次序俯冲投弹了。一声声爆炸，震得地面都在跳动。“新校舍起火了！”好几个学生同时叫。只见新校舍上空浓烟滚滚，是中了炸弹。

    “卣辰！卣辰在实验室！”弗之猛然想到，心里一惊，恨不得走过去看个明白。庄卣辰本来已经接受劝说，不守实验室，参加跑警报。近来因为学校购买了两件珍贵仪器——光谱议和墙式电流器，他总觉得走开不放心。几次空袭都没有飞机来，他认为跑出去实在浪费时间，不如留着看书思考问题，倒是清静。光谱仪的核心是光栅，体积不大，可以拆下带走，但卣辰觉得带出去不安全，总之是不如守着。

    他坐在实验桌前，读一本新到的物理杂志，那是1938年春剑桥大学出版的。四周很静。他解开长衫领扣，读得专心，没有听见远处的隆隆声。及至飞机轰鸣直追头顶，他才猛然意识到敌机来了。

    窗外红光一闪，巨大的爆炸声震得他跳起来。眼看着一排排校舍倒塌下来，洋铁皮屋顶落下时发出金属的声音。“这样近！”他想，下意识地取出光栅掩在衣襟中，又把值夜的棉被盖住电流器，才走至门外。敌机飞得很低，似乎对准了他，机舱中的人清晰可见。又是一声天塌地陷般的巨响，他什么也不知道了。

    庄卣辰醒来时，发现自己好好站着。他倒不了，因为半截身子埋在土中。他仍紧紧抱着光栅。光栅完好无损！这时还没有救解除警报，人们纷纷回到新校舍来救护。人们跑过来时，见庄先生如一尊泥像，立在废墟上，眼泪将脸上泥土冲开两条小沟。庄先生在哭！人们最初以为他是吓的，很快明白了他哭是因为高兴，为光栅的平安而高兴！

    “发现两个人！恐怕已经死了！”救火的人跑过来报告。很快有学生认出，两位死者是化学系学生，参加步行团由长沙到昆明的。他们像千百万青年一样，有热血，有头脑，有抱负，原是要为国为民做出一番事业的，可怜刹那间便做了异地望乡之鬼！

    火场上飘过来白烟，似要遮住一切。孟弗之和梁明时，还有其他人等都肃立，良久不语，一任浓烟缠绕。

    只有那蓝天依旧，蓝得宁静，蓝得光亮。它没有留下一点敌机破坏的痕迹，它这样宽阔，这样深邃，连妖魔鬼怪也都能融成美丽的蓝。

2020年11月24日，我国在中国文昌航天发射场，用长征五号遥五运载火箭成功发射探月工程嫦娥五号探测器，火箭飞行约2200秒后，顺利将探测器送入预定轨道，开启我国首次地外天体采样返回之旅。据了解，距人类上一次从月球采样至今，已有40多年的时间没有拿到新的月球样品。科学家表示，将月球的月壤等关键性样品运回地面实验室供科学家进行精准分析研究，有利于进一步了解月球的状态、温度、物质含量等重要信息，深化对月壤、月壳和月球形成演化的认识。

    Do you still remember your favorite poem from high school or some other important periods in your life？Why is it that decades later it still stands out in your mind？Probably the main reason is that some aspects of that poem resonates(引起共鸣)with you．In the same way，you too as a school leader can touch the hearts of your staff and students．

    Poetry allows us to experience strong spiritual connections to things around us and to the past．Thus，it can inspire whatever and whomever it touches．The power that poetry has displayed over time and across cultures actually satisfies this common need of the human heart and soul．

    As one of the oldest art forms，poetry has successfully connected various strands of humanity(人性)from one generation to another．Referring to poetry，Hillyer makes a simple yet meaningful statement，“With this key mankind unlocked his heart．”

    School leaders can find and make use of the value of poetry for themselves，their students and their staff members．Beyond the simple use of poetry，techniques of poetry such as metaphors，repetitions and imagery can be used to take advantage of the power of language to transform communication，create meaning and a culture of care and attention．

    Since schools are mainly about people and relationship，school leaders，like poets，are required to inspire and encourage the human heart．The use of poetry—or even of some techniques of poetry—in school leadership not only helps to improve communication，but also serves to meet the human need for inspiration．

    There is an old Spanish saying which states, “Tomorrow is often the busiest day of the week.” How many times have we put off our dreams tomorrow? We have to go for them now!

Tomorrow is not promised.

    Nobody likes to talk about death, but everybody is going to die at one point. None of us know the day or the hour. Don't go to your tomb(坟墓) with unrealized dreams. Make the decision to go after every dream, big or small right now.

    One of the biggest dream killers is fear. Many people could have achieved amazing things if only they weren't afraid. Just think about all the things you've wanted to go, but allowed fear to convince you that you weren't talented, or good enough. Fear is not real. It is a product of thoughts you create.

Take action to realize your dream.

    You can dream about writing a great play, but it's never going to happen unless you actually put pen to paper. You can dream about finding a cure for cancer, but it will never happen unless you actually become equipped with the necessary tools to find that cure.

Possibilities are waiting on you.

    There are so many amazing opportunities and people waiting on you. How do you get to them? Simple! Follow your dream. You'll never see those doors if you sit around waiting on a dream to happen, instead of actually working to make it happen.

How can I fight laziness?

    Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.

    . Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.

    Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more protective approach, viewing each task as a challenge they must overcome alone.

    Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. Create a reward system for yourself, just as parents do for a child to promote responsibility.

    Spouses(配偶) and children may all have different energy levels, but laziness can be spread if not dealt with immediately. To fight household laziness, lead by example. Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.

    enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.
