第一空不填是为什么？怎么翻译，后面那个为什么填a

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 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.

Good morning /afternoon /evening, ladies and gentlemen, sorry, ”boys and girls” may be better .It"s really a challenge for me to stand here today and you can see that clearly from my trembling voice .So there is no doubt that giving a speech fluently is a bigger challenge for me, who used to be a shy boy during my past 20 years.Today I choose to face it, because I know this is just the beginning of my challenging college life .Many challenges are still waiting for me ahead .As a freshman, I have already feel the pressure from studying .Classmates and friends around me study hard just like our past senior middle school period . The dreamy college life is still in my dream. We have to admit that more students are gaining access to college with the help of expanded enrollment, but we can not fail to see the fact that the competition is much fiercer than before .Besides, the competitive world today has also brought the “Knowledge Economy”, which requires the effective use of knowledge for economic and social development, and also requires skilled and multi-oriented students with a marketable vocational sense.But when we consider the problem in another point of view, we will find many opportunities for us college students. When a multitude of young men ,keen , open-hearted, sympathetic, and observant, come together and freely mix with each other, they are sure to learn one from another; the conversation of all is a series of lectures to each, and they gain for themselves new ideas and views, fresh matter of thought. In addition, the growing dimension of knowledge sources, such as the World Wide Web, library and multimedia sources provide us with opportunities for bringing out the creativity and talent that we have within us.Ladies and gentlemen, as Charles Dickens once commented upon the time of the French Revolution, "It was the best of times; it was the worst of times." So it is with our time. I believe, if we can make full use of the opportunities and deal with the challenges correctly, we will make it sooner or later. Thank you!

超越的挑战吧。

meet是“见、碰到”的意思,和主语是主动关系,所以在这句话中可以引申为“接受”的意思

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.

雨中，整个大地焕然一新，仿佛给大地挂上了一层簿簿的帘子。小树们贪婪吸着雨露，爱美的花儿们脱下自己五颜六色的长裙，松鼠孩子躲在树枝下，摊开小手接着水滴，并兴奋的叫着下雨啦下雨啦。树林是那么安静，只有雨打在落下的树叶上，融入泉水中，滴在每一个小动物的脸上。雨，如丝如缕飘向森林，织起了一张无崖的绿茸茸的地毯。 不知不觉我来到了田野。我环顾四周，你看田野里层层梯田一片金黄，一人高的玉米，像老人捋着胡子笑口常开，沉甸甸的金黄色的谷子向你低头鞠躬表示欢迎。红通通的苹果，黄澄澄的梨，红玛瑙似的大枣子，咧开大嘴的石榴，灯笼似的西红柿，金黄的稻田里，已有农民在开镰割稻，这是胜利的秋天，丰收的秋天。

冷秋月才是最悲催的

信号发生器一般区分为函数信号发生器及任意波形发生器，而函数波形发生器在设计上又区分出模拟及数字合成式。众所周知，数字合成式函数信号源无论就频率、幅度乃至信号的信噪比（S/N）均优于模拟，其锁相环（ PLL）的设计让输出信号不仅是频率精准，而且相位抖动(phase Jitter)及频率漂移均能达到相当稳定的状态，但毕竟是数字式信号源，数字电路与模拟电路之间的干扰，始终难以有效克服，也造成在小信号的输出上不如模拟式的函数信号发生器。 谈及模拟式函数信号源，结构图如下：这是通用模拟式函数信号发生器的结构，是以三角波产生电路为基础经二极管所构成的正弦波整型电路产生正弦波，同时经由比较器的比较产生方波。 而三角波是如何产生的，公式如下： 换句话说，如果以恒流源对电容充电，即可产生正斜率的斜波。同理，右以恒流源将储存在电容上的电荷放电即产生负斜率的斜波，电路结构如下： 当I1 =I2时，即可产生对称的三角波，如果I1 > >I2，此时即产生负斜率的锯齿波，同理I1 < < I2即产生正斜率锯齿波。 再如图二所示，开关SW1的选择即可让充电速度呈倍数改变，也就是改变信号的频率，这也就是信号源面板上频率档的选择开关。同样的同步地改变I1及I2，也可以改变频率，这也就是信号源上调整频率的电位器，只不过需要简单地将原本是电压信号转成电流而已。 而在占空比调整上的设计有下列两种思路： 1、频率（周期）不变，脉宽改变，其方法如下： 改变电平的幅度，亦即改变方波产生电路比较器的参考幅度，即可达到改变脉宽而频率不变的特性，但其最主要的缺点是占空比一般无法调到20%以下，导致在采样电路实验时，对瞬时信号所采集出来的信号有所变动，如果要将此信号用来作模数（A/D)转换，那么得到的数字信号就发生变动而无所适从。但不容否认的在使用上比较好调。 2、占空比变，频率跟着改变，其方法如下：将方波产生电路比较器的参考幅度予以固定（正、负可利用电路予以切换），改变充放电斜率，即可达成。 这种方式的设计一般使用者的反应是“难调”，这是大缺点，但它可以产生10%以下的占空比却是在采样时的必备条件。 以上的两种占空比调整电路设计思路，各有优缺点，当然连带的也影响到是否能产生“像样的”锯齿波。 接下来PA（功率放大器）的设计。首先是利用运算放大器（OP) ，再利用推拉式(push-pull)放大器（注意交越失真Cross-distortion的预防）将信号送到衰减网路，这部分牵涉到信号源输出信号的指标，包含信噪比、方波上升时间及信号源的频率响应，好的信号源当然是正弦波信噪比高、方波上升时间快、三角波线性度要好、同时伏频特性也要好，（也即频率上升，信号不能衰减或不能减太大），这部分电路较为复杂，尤其在高频时除利用电容作频率补偿外，也牵涉到PC板的布线方式，一不小心，极易引起振荡，想设计这部分电路，除原有的模拟理论基础外尚需具备实际的经验，“Try Error”的耐心是不可缺少的。 PA信号出来后，经过π型的电阻式衰减网路，分别衰减10倍（20dB)或100倍（40dB),此时一部基本的函数波形发生器即已完成。（注意：选用π型衰减网络而不是分压电路是要让输出阻抗保持一定）。 一台功能较强的函数波形发生器，还有扫频、VCG、TTL、 TRIG、 GATE及频率计等功能，其设计方式在此也顺便一提： 1. 扫频：一般分成线性（Lin)及对数（Log)扫频； 2. VCG：即一般的FM，输入一音频信号，即可与信号源本身的信号产生频率调制； 上述两项设计方式，第1项要先产生锯齿波及对数波信号，并与第2项的输入信号经过多路器（Multiplexer)选择，然后再经过电压对电流转换电路，同步地去加到图二中的I1、I2上； 3. TTL同步输出：将方波经三极管电路转成0(Low)、5V(High)的TTL信号即可。 但注意这样的TTL信号须再经过缓冲门（buffer)后才能输出，以增加扇出数（Fan Out)，通常有时还并联几个buffer。而TTL INV则只要加个NOT Gate即可； 4. TRIG功能：类似One Shot功能，输入一个TTL信号，则可让信号源产生一个周期的信号输出，设计方式是在没信号输入时，将图二的SWI接地即可； 5. Gate功能：即输入一个TTL信号，让信号源在输入为Hi时，产生波形输出，直到输入为LOW时，图二SWI接地而关掉信号源输出； 6. 频率计：除市场上简易的刻度盘显示之外，无论是LED数码管或LCD液晶显示频率，其与频率计电路是重叠的，方块图如下：2. 任意波形发生器，仿真实验的最佳仪器 任意波形发生器是信号源的一种，它具有信号源所有的特点。我们传统都认为信号源主要给被测电路提供所需要的已知信号（各种波形），然后用其它仪表测量感兴趣的参数。可见信号源在电子实验和测试处理中，并不测量任何参数而是根据使用者的要求，仿真各种测试信号，提供给被测电路，以达到测试的需要。 信号源有很多种，包括正弦波信号源，函数发生器、脉冲发生器、扫描发生器、任意波形发生器、合成信号源等。一般来讲任意波形发生器，是一种特殊的信号源，综合具有其它信号源波形生成能力，因而适合各种仿真实验的需要。 一、函数功能，仿真基础实验室设计人员的环境 函数信号源是使用最广的通用信号源，它能提供正弦波、锯齿波、方波、脉冲串等波形，有的还同时具有调制和扫描能力，众所周知，在我们的基础实验中（如大学电子实验室、科研机构研究实验室、工厂开发实验室等），我们设计了一种电路，需要验证其可靠性与稳定性，就需要给它施加理想中的波形以辨别真伪。如我们可使用信号源的DC补偿功能对固态电路控制DC偏压电平；我们可对一个怀疑有故障的数字电路，利用信号源的方波输出作为数字电路的时钟，同时使用方波加DC补偿产生有效的逻辑电平模拟输出，观察该电路的运行状况，而证实故障缺陷的地方。总之利用任意波形发生器这方面的基础功能，能仿真您基础实验室所必须的信号。 二、任意波形，仿真模拟更复杂的信号要求 众所周知，在我们实际的电子环境所设计的电路在运行中，由于各种干扰和响应的存在，实际电路往往存在各种信号缺陷和瞬变信号，例如过脉冲、尖峰、阻尼瞬变、频率突变等（见图1，图2），这些情况的发生，如在设计之初没有考虑进去，有的将会产生灾难性后果。例如图1中的a处过尖峰脉冲，如果给一个抗冲能力差的电路，将可能会导致整个设备“烧坏”。确认电路对这样一个状况敏感的程度，我们可以避免不必要的损失，该方面的要求在航天、军事、铁路和一些情况比较复杂的重要领域尤其重要。 由于任意波形发生器特殊的功能，为了增强任意波形生成能力，它往往依赖计算机通讯输出波形数据。在计算机传输中，通过专用的波形编辑软件生成波形，有利于扩充仪器的能力，更进一步仿真模拟实验。同时由于编辑一个任意波形有时需要花费大量的时间和精力，并且每次编辑波形可能有所差异这样有的任意波形发生器，内置一定数量的非易失性存储器，随机存取编辑波形，有利于参考对比；或通过随机接口通讯传输到计算机作更进一步分析与处理。 三、下载传输，更进一步实时仿真 在一些军事、航空、交通制造业等领域中，有些电路运行环境很难估计，在实验设计完成之后，在现实环境还需要作更进一步实验，有些实验的成本很高或者风险性很大（如火车高速实验时铁轨变换情况、飞机试机时螺旋桨的运行情况等），人们不可能长期作实验判断所设计产品（例如高速火车、飞机）的可行性和稳定性等；我们就可利用有些任意波形发生器波形下载功能，在作一些麻烦费用高或风险性大的实验时，通过数字示波器等仪器把波形实时记录下来，然后通过计算机接口传输到信号源，直接下载到设计电路，更进一步实验验证。 综上所述，任意波形发生器是电子工程师信号仿真实验的最佳工具。我们选购时除关心传统信号源的缺陷——频率精度、频率稳定度、幅度精度、信号失真度外，更应关心它编辑与波形生存和下载能力，同时也要注意它的输出通道数，以便同步比较两信号的相移特性，更进一步达到仿真实验状态。 图1 有尖脉冲的数字信号 图2 有频率突变的方波

2hm应该是两百米，如果是hm2就是公顷。

今天中午受到了老师的批评，炽热的太阳发着刺眼且毒辣辣的白光，树上的蝉儿烦躁地声嘶力竭地鸣叫着，就像是在催命，小草耷拉着脑袋，无精打采地立在路边，大树也绿得格外耀眼，弄得我心烦意乱。几只麻雀正叽叽喳喳地叫着，那声音跟乌鸦没什么两样，又像是在嘲笑我的无能。花儿也在左右摆动，仿佛在对我摇头；一群蝴蝶围着花儿飞着，好像十分赞同花儿的想法。瞧，蜜蜂也在花儿旁转了起来，它也支持花儿哩几朵白云不死不活地游荡在天上，比乌云还要令人心烦。……一切都像在跟我作对。

鹿三要杀死田小娥，其实是一个时代的悲剧。即使放到现在，说实话，如果在村子里出现黑娃和田小娥这样的感情，大多还是不会被看好的吧？依然会受到指指点点的吧？（我没有歧视农村的意思，我也是农村娃，我的意思不管是过去还是现在，农村里的思想还是保守一些）。鹿三是个典型的传统农民，他虽然地位不高，但他的骨子里是受封建礼教洗礼的，他看不惯一切有违于传统道德的人和事，而很不幸的是。偏偏这个女子是自己的儿子带回来的。她不仅是”害得“黑娃的婚姻不被祝福，不能进祠堂，还在黑娃走后频频的闹出风流韵事，让自己在整个原上抬不起头，最后更是毁了白孝文（这是他的认为），让在自己心中一直至高无上的族长白嘉轩也颜面扫地。这时候，除了杀了她，鹿三还能有什么办法？也许，他认为杀了她，就可以结束这一切，包括自己的屈辱。但是实际上，杀了田小娥之后的鹿三，并没有随之而来的轻松。他随即惊恐地发现，田小娥的鬼魂缠上了自己。这当然不是作者在宣传封建迷信思想的，至于被附身完全是无稽之谈，这是鹿三杀过小娥后内心做残酷挣扎和被无情折磨的结果，虽说杀人是他自愿的事，但毕竟他杀了一个人，一个活生生的生命被他终结。

15亩。hm2是面积单位（其中2为上标），表示公顷，一般用于土地积的计算。其中h表示百米，hm2的含义就是百米的平方（英文为square hectometer），也就是10000平方米，即公顷。 另外公顷还可以用ha表示，是面积单位公顷（hectare）的英文缩写。国内不推荐使用ha 我国规定的土地面积单位有三个：平方米(m2)，公顷(hm2)，平方公里(km2)。 我国在官方正式统计的场合一般用平方公里（km2）和公顷（hm2）来表示，比如某地区面积为多少平方公里，某种植园面积为多好公顷；但在广大的农村以及民间采用的土地面积单位为亩，1亩 = 10000平方米/15亩 =666.7平方米

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。

hm2是面积的公制单位（国际单位），表示公顷，一般用于土地面积的计算。比如某地区面积为多少平方公里，某种植园面积为多少公顷。一块面积一公顷的土地，大约与标准足球场近似。

黄昏在江边漫步，秋水盈盈，一弯新月，像金钩斜挂半空。微风不动，水波不兴，天上一牙，遥对水底一牙。心情说不出的舒畅。下弦月冉冉升起，已经是夜静时分。万里长空，无云一碧，皎皎明月光，给整个天地渡了银，又像把偌大的人寰装进了水晶瓶里。月光洒遍粼粼的江上，闪闪烁烁，泛起万点荧光。极目远处，月下有一二轻舟，静悄悄不闻橹声，便激起一朵耀眼的银花

我国选定hm2作为“公顷”的符号，国际上则用ha(hectare)，hm2是square hectometer的符号土地面积习惯用hm2（公顷）作单位；领土面积习惯用km2 作单位。1 1hm2=10000 m2

1.清晨，拉开窗帘、推开窗户。微风吹来，一阵清新、幽香、淡雅的泥土气息迎面而来。春天来的好快，悄无声息、不知不觉中，草儿绿了，枝条发芽了，遍地的野花、油菜花开的灿烂多姿，一切沐浴着春晨的曙光，在春风中摇弋、轻摆，仿佛少女的轻歌曼舞，楚楚动人。生物在春晨中醒来，展示着生命的可贵、诱人。春晨点染心中的希望，激发着人生的热情。自然世界此刻是如此的美丽：到处放射着明媚的阳光，到处炫耀着五颜的色彩，到处飞扬着悦耳的鸟叫虫鸣，到处飘荡着令人陶醉的香气。这是绿的世界、花的海洋。到处是郊游踏青的人群，有老年人的慈爱满意，有情人的欢乐开怀，有孩子的天真笑容。恍忽间明白：春光明媚的春天之所以如此的美，是因为它让人的心情在此刻绽放。2.春雨和着春雷、随着春风、淅淅沥沥飘来。春雨如丝、如雾、如烟、如潮。透着这缕缕蚕丝，世界的万物如同淡淡、蒙蒙的写意画，忽隐忽现。我喜欢春雨，不光喜欢它换来的雨后春笋的英姿，更喜欢的是：踏进这淡蓝色的烟雨，在这雨季，你为我撑出的一片无雨的天地。3.春是活泼的、春是狂热的、春是姿意生长的、春是年青旺盛的。春天到处是人们辛勤的影子，人们用自己的双手播种着他们的坚定的信念和永远不变的希望，播种着真执的情和无私的爱。没有春的万紫千红？哪来秋的硕果累累？4.春天的夜晚，淡月笼纱，娉娉婷婷。有风拂过脸颊，掠起长发。月光如水平静柔和。我心如这月光，平静柔和。不敢去刻意追求什么，只是希望所有美好的开端都有一个美好的结局，一如这春夜长长远远。5.春天在哪儿呢？到大自然中找春天去！春在枝头，柳条嫩绿，桃花鲜艳。春在空中，和风送暖，燕子翻飞。春在水里，鱼儿追逐，鸭子戏水，春在田间，麦苗返青，菜花金黄。到处都有春天，春满人间！摘抄赏析仿写一段景物描写200字

hm2是面积单位（其中2为上标），表示公顷，一般用于土地面积的计算。其中h表示百米，hm2的含义就是百米的平方（英文为square hectometer），也就是10000平方米，即公顷。 另外公顷还可以用ha表示，是面积单位公顷（hectare）的英文缩写。国内不推荐使用ha。 我国规定的土地面积单位有三个：平方米(m2)，公顷(hm2)，平方公里(km2)。 我国在官方正式统计的场合一般用平方公里（km2）和公顷（hm2）来表示，比如某地区面积为多少平方公里，某种植园面积为多少公顷；但在广大的农村以及民间采用的土地面积单位为亩，1亩=666.7平方米，1公顷 = 10000平方米=15亩 。
