求一篇英语演讲稿Challenges and opportunities for college students in today`s competitive world?

挑战（复数）

today we are facing with various kinds of challenges， either from the outside or from the insdide。 challenges are there waiting for people to cope with。and people love to face challenges。because challenges make our life more interesting and changeable instead of boring。a challenge is what we can not solve easily without trying very hard。 also challenges let people try hard to face what they do not want to face。it is a process of self-improving and self-realizing。the key to face challenges is face ourselves。the very thing people have to conquer is ourselves。 without challenges our society can not move on

个人感觉不一样，原因是face这词（facing).和(faced),觉得ing是即将面对的/将要面对的、、的挑战，而faced则是正摆在你面前、、的挑战。 只是个人意见。

challenges挑战双语对照词典结果：challengesn.挑战( challenge的名词复数 ); 要求; （警卫等）查问口令; 怀疑; 以上结果来自金山词霸例句:1.India has faced challenges on other fronts. 印度在其它方面也面临挑战。-----------------------------------如有疑问欢迎追问！满意请点击右上方【选为满意回答】按钮

challenges 这里的结构是one of + 形容词最高级 + 名词复数,意思是最……之一,所以用challenge的复数challenges.

看上下文eg.Why you always challenge me?一而再再而三挑战我底线？

challenges生词本去背诵[ˈtʃælindʒz]n.挑战( challenge的名词复数 )； 要求； （警卫等）查问口令； 怀疑网 络面临的挑战；方面的挑战；考验；挑战方面. The secret to happiness is to keep setting yourself new challenges. 幸福的秘诀就是要不停地给自己设定新的挑战。

“challenges remaining”挑战继续，有点类似，接着来的意思。

文法上没有问题，但是表达意思有点不妥：challenges 它们不会自己找上门， 所以 “challenges confronting organizations” 这个说法不太通。可以考虑下面的表达方式：1. 。。。。。inspire more imaginative responses when facing challenges (或者 when their organisations are faced with challenges).2. .......inspire more imaginative responses when encountering problems/crisis (或者 when their organisations encounter problems/crises).用 facing、faced with 这些来 连接 challenges/problems/crises 等等会更能表达意思。希望帮到你。

你好!challenges，and opportunities挑战和机遇

lying ahead为 宾语补足语。宾语challenges用来修饰challenges的位于前方的 的意思翻译成中文可省略嘛

本句中 annoying 是形容词作定语修饰challenges 。facing the middle class是现在分词短语作后置定语修饰the annoying challenges。其逻辑主语就是前面的名词challenges。即challenges face the middle class。可以理解成“面对着 中产阶级 的 挑战”.翻译时可以倒过来，即”中产阶级面对的挑战”本句是倒装句among介词短语是表语。 is 是系动词。one 是主语，后面是定语从句。其中that 代替先行词作定从中的主语，will probably go 是定从中的系动词unmentioned 是定从中的表语in the next presidential campaign是定从中的状语。引号后面是说明one的句子: （中产阶级面临的恼人挑战之一：当机器要抢占他们的工作时，会发生什么？而这个问题在下届总统竞选时很可能被忽略。）

ChallengeWith the fast development of the world, we will face more and more challenges. Challenge means not only hardship, but also opportunity. Since we are young people and have glorious future before us, we should not be afraid of challenge. Challenge can inspire our creative power and lead us to success. The most important thing is to deal with challenge properly.First, we must get ready for challenge at any time, because it comes all of a sudden. Second, you should be courageous enough to face up to it. No pains, no gains. Only through hard work can we achieve success. Finally, make sure that we have adequate knowledge to help us deal with challenge. As for me, I have my own ways to deal with challenge, I"m always trying to challenge myself and conquer myself. Only by means of this can I achieve my ambitious goal.

My view on challenge There is no consensus of opions among people as to the view of challenge.Some one believe that challenges make people who face it to be more diligence while some other people think that challenges in ever increasing number in our society make our lifstyle to a hurry way fulling of stress.As far as I am concerned,I agree with the former opinion.Though people live in the 21 century have to endeavor to studying and working to keep pace with the society in which new challenges waving out everyday,on the other hand,people earn more convinient and flourish life than ever before by consider these challenges as opportunities to make change.In practice,challenge means more positive,more durable and morre brave for failure.We can reform our mind and life by facing challenge in good ways.It will at least motivate us not to be lazy but be in a standby status everyday.

.夕阳落山不久，西方的天空，还燃烧着一片橘红色的晚霞。大海，也被这霞光染成了红色，而且比天空的景色更要壮观。因为它是活动的，每当一排排波浪涌起的时候，那映照在浪峰上的霞光，又红又亮，简直就像一片片霍霍燃烧着的火焰，闪烁着，消失了。而后面的一排，又闪烁着，滚动着，涌了过来。天空的霞光渐渐地淡下去了，深红的颜色变成了绯红，绯红又变为浅红。最后，当这一切红光都消失了的时候，那突然显得高而远了的天空，则呈现出一片肃穆的神色。最早出现的启明星，在这深蓝色的天幕上闪烁起来了。它是那么大，那么亮，整个广漠的天幕上只有它在那里放射着令人注目的光辉，活像一盏悬挂在高空的明灯。

最近我俩口子一起追剧《白鹿原》。剧中人物田小娥是我俩分歧最大的一个角色。女人观点： 我认为小娥一个女人家太可怜。命运凄苦。白白长了一幅好皮囊，却要遭受那么多臭男人坏男人的糟蹋。 她年纪轻轻被贪图钱财的亲爹卖给一个有钱的老头子。过着生不如死的日子。遇见黑娃，尝到了爱情的滋味，酸酸甜甜让她不能自拔，无论黑娃多穷都要跟他一起走天涯。 可惜在那个年代被夫家休回家的女人就永无翻身之日，终身都要背负着贱女人狐狸精的骂名。 小娥生性本善，她渴盼着自己也能如普通女子一般正大光明进婆家门，正大光明进白鹿原祠堂。她偷偷溜进祠堂跪拜白鹿原祖先，求祖先阴护。她询问孝文，做过错事的人是不是永远都是错的。孝文告诉她只要认真做好事，终究会得到别人的尊重。这给她心里种下希望的种子。 她本想和黑娃安安稳稳过日子，用自己的吃苦耐劳兑换白鹿原父老乡亲们尊重的眼神。 可惜世道弄人，黑娃被鹿兆鹏鼓动参加革命队伍，抛下小娥一个人在荒郊野外的寒窑里苦熬日子。 一个年轻漂亮的女人，孤苦伶仃，过着没有白日黑夜的日子，只期盼自己的男人能够平安归来。比苦日子更黑暗的是人心，那些天生用下肢思考问题的男人对小娥的美色垂涎三尺，用最阴暗恶毒的办法断了小娥的念想，造谣说黑娃死了。小娥生命中最后的生命稻草也被压垮了。她活着如同死去一般。 但人心恶毒，小娥成这样还要被人利用当枪使，让她拿自己的身子去给小人鹿子霖当做对付白嘉轩的武器。 小娥太可怜了！看得我心好疼。心疼的同时我为小娥惋惜，为什么遇到难处的时候去找渣人鹿子霖帮忙，最后被坏人利用。为什么不去找白嘉轩！白嘉轩虽然威严的足以让人心颤，但是他是好人。绝不会在小娥难处时再推小娥一把。 边看电视我边唏嘘，心疼可怜的小娥。老公却和我的观点截然相反。他对小娥嗤之以鼻，看不上这个生性淫荡的女子。 男人观点： 小娥虽然生的美，但天生媚骨，这样的女人性欲旺盛，不是居家过日子的良家妇女。她被卖给老头子是命运不济，但对黑娃，是她主动勾引年轻不经事的壮年后生。黑娃的强壮性感让她放下女人该有的矜持和自尊主动去撩拨黑娃。说白了，小娥就是个花痴。黑娃参加革命军远走他乡，留下小娥一人。鹿子霖趁机想要欺负小娥，最后结果是小娥确实和鹿子霖干了苟且之事。因为小娥本性淫荡，她根本就收不住妇道，不是鹿子霖，换做其他任何男人，小娥也会从。看似小娥被逼的，其实小娥是半推半就。 小娥在祠堂被人人鞭打一幕，看的我泪流满面。觉得那个年代对女人太不公平，女人连说理的地方都没有。 老公对一脸鄙夷。说这样水性杨花女子，活该如此下场。为此我俩使劲拌嘴。 总结我俩不同的说法，归根结底是一点不同： 我认为小娥生性本善。他认为小娥生性淫荡。 以上观点仅代表个人观点。各位看官可以各抒已见，发表个人观点。轻拍。

【短句】夜色苍茫，星斗阵列，万籁俱寂//夜半，月儿偏西，星斗满天，露水浮地，一片凉意//灯光、月光、星光交映的树荫下，夜晚显得幽沉、朦胧、迷幻，大地像被轻纱罩着//天空晴朗鲜明，众星齐现，大地静卧在平安的夜里//入夜，繁星点点，灯光迷离，银星和灯珠衔接在一起，分不清那是星河那是灯海//黑夜蜷缩着，紧抱着大地，大野阴沉沉，夜像怪兽一样张着黑洞洞的大口//晚上出奇的黑，没有星星也没有月亮，黑得如同把地球扣在锅底下//墨黑的夜粘住了每个角落，还染乌了每一颗心//天空黑漆漆的，星星全给乌云吞没了//天黑下来，大地森森然，好像回到了原始时代//周围黑沉沉的，夜幕遮天盖地地落了下来//夜幕像黑丝绒般浓重了，星星也更像钻石//夜太黑了，眉一样的上弦月很早就沉落下去，地面上的景物都难以分辨//天上的星斗似乎怕冷，又像是怕风，全都没入黑漆漆的天幕//隆冬的子夜异常静谧，万籁无声//星月交辉，周围静悄悄的，只有树叶被凉风吹着，发出轻微的沙沙声//夜，村庄静悄悄的，睡在白色公路的两旁，像孩子那样安宁香甜//静夜与明湖悄然并卧于圆月之下//夜色浓暗，田里和山里除青蛙的合唱和雀子的啼叫，听不见别的声息//这是一个月色朦胧的夜晚，周围静极了，仿佛一枚绣花针掉在地上都能听得见//风不吹了，狗也不叫了，整个村庄都进入静静地沉睡中//夜的草原是那么宁静而安详，只有漫流的溪水声引起人对大自然的遐思

一夜秋风过后，院子已经充满了萧条的气息，落叶满地，竟也无人像黛玉般怜惜它们。南飞的大雁恋恋不舍地离开这片乐土，去开辟另一片陌生的天地。轻轻地踏上铺满落叶的小径，沙沙声时断时续，哭诉着着它们悲惨的命运。天空不再像春夏那样透露着水的灵性，干燥的季节，无奈的风景。一只乌鸦在头顶的树枝上叫个不停，乱了节奏，扰了人心，此刻，竟也无力理会它的晦气，独自低头，在这悲伤的秋景中越陷越深。一颗千年古树，树叶稀疏，枝干粗大，裂痕斑斑，错综复杂的树枝像瘦骨嶙峋的人一样没了活力。它的叶，没有花的陪伴，愈发的苍白；它的枝，没有鸟儿的嬉戏，愈发的落寞；它裸露的根，没有泥土的滋润，愈发的干枯。是否像年老的智者一样，它也经历着孤独与衰亡。又有谁能来拯救它将逝去的生命，或许作为建筑的材料它已经不再合适，徒留叹息在一片篝火之后。

黑夜从大地上升起,遮住了光明的天空.举目望着夜空,月亮闪动着深情的目光.许多星星就象一颗颗珍珠在夜空中明灭闪耀着.天空格外地清亮,深黑的底色也仿佛变得蔚蓝起来.星月朗照下的世界,呈现一片温柔动人的景象.一条清冽的河从远处朦胧的夜色里飘然而至眼前.两岸及不远处的桥上,一片片阑珊的灯火,伴着星月的光亮,将河水照耀得清晰碧透.远处使人尚可辨认出那是一片茂密的树林.或许,它们正在静谧中演绎着浪漫.而远处山伫立在月下.连绵起伏的线条,与近处河岸柔滑的曲线交错缠绵,完美地点缀着这如诗如画的夜景.这是真正宁静而美丽的夜晚.

8选1数据选择器：通过对3位地址线的控制，是8为二进制数据只有一路送到输出上。因为8个中只能有一个到达，因此叫数据选择器。数据选择器(data selector) 根据给定的输入地址代码，从一组输入信号中选出指定的一个送至输出端的组合逻辑电路。有时也把它叫做多路选择器或多路调制器(multiplexer)。

document 理解为整个HTML文档就好了。在JS里，通过这个来对整个HTML文档内容进行操作。大概就是这么回事了。

先笼统些一下公园的周边环境引出公园，再由公园的细节入手，可以是雕像，可以是人造景物，之后整篇按照由近到远，或由远到近的顺序写，最后一段抒发下自我感叹就行，这种作文肯定都是初中，或是小学作文，高中没有这么出题的。春天，黄山湖公园里的花张开了笑脸，仿佛在对太阳公公笑，小草也钻出了脑袋，懒洋洋地打着哈欠，从地里钻了出来，远远地看小草是那么浓郁，但近看却一点也不浓郁，真是“草色遥看近却无”啊！一只只勤劳的蜜蜂踩着花蜜，一只只漂亮的蝴蝶在花丛中翩翩起舞。春天的黄山湖公园是热闹非凡的。人们趁着这大好时光到公园里去散步，有的孩子跟着自己的父母一同去公园里玩，有的看到自己熟悉的伙伴的话，大人们就在一起聊天，小孩就在一起嬉笑追逐着，春天的黄山湖公园是热闹非凡的。 夏天，黄山湖公园那参天大树的底下是人们避暑的好地方。中午，有许多的人都漫步在黄山湖公园，都在树荫下乘凉，谈天说地的，看上去既悠闲又高兴的样子。到了夜晚，路边齐灯开放，一根根耸立的棕榈灯柱射出银白色的光，是那么柔和，那么温馨。地面玻璃下的盏盏小灯，似星光引路，提醒着市民一路走好，路两边的绚丽无比，如礼花绽放，如瀑布飞泻，如骏马齐奔，那红、橙、黄、绿、青、蓝、紫的光彩跟人射灯交相辉映，使人仿佛置身于灯的海洋，让人目不暇接，留连忘返，人们坐在岸边，他们脚下是海浪于堤岸的呢喃细语。 走出了夏日的温馨，黄山湖公园进入了秋的美丽。俗话说“十月桂花香”，只要到桂花开的日子里，你刚走进黄山湖公园，那桂花真是十里飘香，让你感到心旷神怡，走都不想走了。你瞧，那里一朵朵、一盆盆的菊花正在怒放，你看，有的菊花花冠细长弯曲，白嫩细腻的瓣上短下长，长部的花瓣如同无数小手伸出，下部的花瓣层层叠叠，像蛟龙的爪子一样刚劲有力，嫩黄的花蕊像玉盘中盛满了灿烂的明珠。 走出秋天的美丽，进入冬天的寒冷。冬天的黄山湖公园是百花凋谢的时候，树叶纷纷扬扬地坠落下来，树头上变得光秃秃的一根树条了。黄山湖公园的玩人也越来越少了，虽然这么说，但是冬天来了，春天还会远吗？
