diff

改成between

difference是差分，derivative是导数，二者本来就不是一回事，与MATLAB无关。

differentiation 是微分，是x->0时的增量，一般数学上表示为dy.derivative是微商,是x->0时，dy/dx的比值，又叫导数。 一般有y`=f`(x)=dy/dx dy=f`(x)dx

一个是求导，一个是微分导数又叫微商，两个微分的商。

我不是这么理解的，我理解THE SEARCH PROVED DIFFICULT 可以是句子。FOR 后面做解释成分,2,prove在这里是"证明是;结果是;事实说明"的意思，用作连系动词，结构是prove+形容词，proved只是表示过去式；The search proved difficult是主句，for引导的则是一个原因状语从句。,2,proved只是过去式，不是被动，这里没必要用被动。 diffcult做表语 （你非要理解成状语，到也讲得通) ，the search proved diffcult是个句子，后面的大长for语句到是个大状语,2,定语，修饰the search,0,有个英语句子不太懂 The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. 请问 The search proved difficult 这不是一个句子吧 proved是过去分词表示被动 这是非谓语动词吧 可是这里的difficult 在这里做什么成分呢？ The search proved difficult 做什么状语

somuch,verymuch都可做副词短语修饰动词，表程度，somuch还可以表示多的意思，但是用来形容不可数名词，但是verymuch不能~

very, much, so 都有“很，非常”的意思。它们之间有什么区别呢？解答如下：我们先来了解一下，这三个词本身都有与别的词不同的意思。它们之间不同的含义应该容易区分。例如：1、very 本身有个特殊的含义，就是起强调作用。例如：Your very presence will do. 你只要出席就可以了。He is the very man that came yesterday. 他正是昨天来的那个人。He was caught in the very act of stealing. 他正在偷东西时当场被捕。2、much 有“许多的, 大量的”的意思，是形容词。例如：He hasn"t much money left. 他剩下的钱不多了。There is not much hope. 无多大希望。Much coal has been saved. 节省大量的煤。3、so 有两个特殊的含意，一是代表前面说过的事物(代词)；而是表示“因为，所以”等(连词)；I think so. 我想是这样。Well, I told you so, didn"t I? 我不正是对你这样说的吗?You say he is dilligent; so he is. 你说他很勤奋, 他确实很勤奋。He was sick, so they were quiet. 他病了，所以他们很安静。It was late, so we went home. 天晚了, 所以我们就回家去了。He was sick, so they were quiet. 他病了, 所以他们 很安静。但这三个词都有一个相同的意思，即都能表示“很、非常” 的意思。用语法的词汇来说就是它们都是表示“程度”的副词。这时，它们有什么区别呢？请大家多看例句，再进行思考小结。1、very 一般只修饰形容词或副词。very quickly 很快a very good cake 很好吃的蛋糕a very exciting book 一本非常有趣的书I am not very fond of music. 我不太喜欢音乐。Refined sugars are absorbed into the bloodstream very quickly. 血液吸收精制糖非常快。Most people have very little difficulty in seeing why a Van Gogh is a work of genius.2、much 有“非常、很”等意思，但它修饰的词类不同。(1) 可以修饰动词I was much surprised at what he said. 我对他的话甚感惊异。This painting is much admired. 这幅油画备受称颂。I like English very much. 我非常喜欢英语。 She is a TV addict and watches as much as she can.她是一个电视迷，能看多少就看多少。(2) 可以修饰比较级She said she was much better than before. 她说她比过去好多了。 How much longer can you wait? 你还能等多少时间？You"d be so much happier if you could see yourself the way I see you...如果你能像我这样看到你自己，你会更加高兴。3、so 也有 “非常，太”等意思；但它还“这么、那么”等意思。(1) 有“非常，太”等意思，修饰形容词。这时可以与very 互换。I"m so glad to hear from you. 接到你的来信, 我非常高兴。It"s so kind of you. 你太好了。I feel so guilty and angry about the whole issue.　对整个问题我感觉非常内疚和气愤。(2) 在表示程度时还有“这么、那么”的意思。so important an event 这么重要的一件事Don"t speak so fast. 别讲得那 么快。Chris is so ambitious, so determined to do it all.　Chris 那么有雄心和决心去做完那件事。(3) so 可以与 many, few, much, little 等连用，表示“这么、那么”的意思。There was so much food that we couldn"t eat it all. 食物太多了，我们吃不完。I"m afraid that he"ll forget it if he misses so many lessons. 我担心的是，如果他耽误这么多的课程他会忘掉的。 Miss Zhao got so little money a month. 赵老师每月只领这么少的钱。

diff 命令是 linux上非常重要的工具，用于比较文件的内容，特别是比较两个版本不同的文件以找到改动的地方。diff在命令行中打印每一个行的改动。最新版本的diff还支持二进制文件。diff程序的输出被称为补丁 (patch)，因为Linux系统中还有一个patch程序，可以根据diff的输出将a.c的文件内容更新为b.c。diff是svn、cvs、git等版本控制工具不可或缺的一部分。 diff命令的格式一般为： diff [参数][文件或者目录1][文件或者目录2] 例如，有文件test1和test2： 将会输出： 格式的含义如注释所示。 diff 的normal 显示格式有三种提示: a - add c - change d - delete 比较常用的是以合并的方式显示两个文件的不同： 输出如： 这种输出方式输出的内容可以用于使用patch命令进行打补丁包。patch命令我们稍后再看。 diff命令也可以比较两个文件夹的不同： 例如有两个文件夹testa和test，将test1和test2放进去： 得到： 第一部分是文件的信息 "---"表示变动前的文件，"+++"表示变动后的文件。 第二部分表示变动的位置 @@ -1,11 +1,5 @@ 减号表示第一个文件，后面的表示第一行起一共11行。加号表示第二个文件。后面是第一行起一共5行。 接下来的表示区别的部分。 例如： 将得到： 这种模式中 “|”表示前后2个文件内容有不同 “<”表示后面文件比前面文件少了1行内容 “>”表示后面文件比前面文件多了1行内容 我们可以先用diff命令生成patch文件。然后使用patch命令将第二个文件内容修改成第一个文件的内容。 例如上述的test1和test2： 之后test2的内容就会和test1内容一致了。 svn diff生成的patch也可以用于更新文件

更新1: how about if I change the second sentence to be she has not yet been sure if she could trust him Never use the second one because it is wrong. The word "sure" can be an adjective or adverb but not a verb. Which one is the verb in the second sentence? If the word "has" is the verb it should be followed by a noun or noun phrase not an adjective or adverb. We dont say "I have tall" right? We will only say "I have a book" or "I have o younger sisters". "She was not yet sure if she could trust him" is in past tense. It me that she was not yet sure in the past but she is probably sure now. "She is not yet sure if she could trust him" is in present tense. It me that until now she is still not yet sure. 2008-06-26 15:27:54 补充： If you want to use present perfect tense you should say "she has never been sure if she could trust him" It me that 她从来未... 不是 tense 的问题. Sure 是 形容词 它之前用 be 或其变体 is are am was were will be has been .... 不用其他动词. 所以 She was not sure 正确. She has not sure 不正确. 有一个方法帮你记忆. 讲英文的人常常挂在口边的 I"m not sure...... 即 "我不肯定" am 和 not sure好像孪生兄弟 总是一起用的. 这样 可以帮我们记着 SURE 之前一定是 BE 或其变体.

机器学习的主要目的是为了从数据中抓取有效信息，而隐私的目的是想要隐藏掉信息（防止个人信息泄露等）。两者看起来有冲突，但是当我们挖掘敏感信息的时候，我们需要平衡这两者之间的关系（保护个人隐私不被泄露的同时抓取到有效信息，从而训练得到一个performance比较好的算法）。所以一个比较常见的方法就是当我们从数据中抓取信息的时候，尽可能的去抓取整个population中比较general的特征，同时保证不透露任何individual的隐私信息。但是往往匿名化数据仍然无法保护个人隐私被泄露。比如说，如果当攻击者掌握了一些其他的泄露信息时，他可以通过合并重叠数据得到他想要的信息。或者通过query多次结果的差异，找到他想要的信息。因此，有人提出，可以把具有相同特征的sample合并成一个group，当整个group中sample数量达到一定程度，可以公开这个group的信息来防止敏感信息被泄露。但是即使这样，攻击者还是可以得到他想要的信息。 比如说， 所以Dwork提出了差分隐私(Differential Privacy)的概念，简单来说就是通过使用随机噪声来确保query公开可见信息的结果并不会因为个体的变化而变化。（有一点类似model stability的感觉，比如我拿走任意一条数据或者增加新的数据并不会对整个model的performance带来很大变化） 比较常见的有三种关于差分隐私的数学定义 这个定义的意思就是对结果加一个随机噪声（Gaussian noise或者Laplacian noise都可以） 这个定义了用 来表示从数据集 变成数据集 的最小的数据变化量。举一个简单的例子，如果两个数据集 和 最多只相差一条数据，那么 . 我们又把这样的pair (D, D") 叫做邻近数据集（dataset neighbours，不知道是不是这么翻译的）。 定义3就是由Dwork提出的差分隐私的default定义了，通过加入随机噪声，输出一个结果的概率分布(that"s the reason we use probability on both sides)。定义中的 表示，当对于数据集和它的任意邻近数据集（表示每一条数据都需要满足），这个机制的结果变化超过 因数的概率（其实就是把不等式右边第二项移到左边）。所以 代表了这个机制的confidence（值越小越confident）， 则表示了隐私保护的标准（值越小，标准越严格，所以又叫做privacy budget）。简而言之，就是当 和 越小的时候，两个probability就越相近，因此隐私保护的就越好。 当我们选择 的时候，我们要注意，当数据集中有n个samples时， 必须要小于1/n。因为显而易见，这个机制可以满足 -differential privacy，但是如果当 的值偏大时，这个机制有很高的概率会导致隐私泄漏。对于这个数据集中的每一条数据，都有 概率会被release出来，因为release每一条不同的数据都是独立的，所以相当于这个机制可以release了 个sample。所以为了防止这样的泄露， 必须要小于1/n. 通常，当 的时候，我们又把这个叫做 -differential privacy. 当 的时候， -differential privacy仍然有 的几率会导致信息泄露，但是当 的时候，就表示，泄露的概率为0，也就是说这个隐私保护不是概率性的，所以 -differential privacy的定义要远强于 -differential privacy。 Reference: [1].

problem是名词"问题".意思相当于question,一般性的或者较难的问题都可以说是problem,使用范围比question广,各个方面的问题都能用problemdifficult是形容词"困难的",difficulty是名词"困难",指比较艰辛,难于完成的事情.与problem的意思有明显的区别.

[1]Difficulty较Problem困难的程度轻：Difficultyn.困难.难点-》比较难.但是可以解决Problemn.问题.难题-》比较难.有可能解决Hehassomedifficultiesdoinghishomework.Butdon＇tworry.Ithinkhecanfinishitbyhimselflater.他做家庭作业有点困难.可是不用担心.我想稍晚些他能自己做完功课.Hehassomeproblemsfinishingthisprojectnowsohehastocheckhisreferencebooks.要完成这个项目他现在有点困难.以至于他不得不翻阅他的参考书.[2]Difficulty意思比较泛，困难，难点，可以是任何事情/任何方面。既可以表达problem代表的待解决的问题，也可以是客观存在的困难，难处，困境。Problem相对来说，是做某事过程中出现的问题，难题，需要解决的某个问题。如：Hehashearingdifficulty.他有听力困难。DoyouhaveanydifficultywithEnglish?你英语上有困难吗？financialdifficulty财政困难,资金困难akeyproblem一个关键问题Theproblemwashowtomovetheheavymachinery.问题是怎样移动这台沉重的机器。

B 考察冠词。Unemployment是一个抽象名词，单独使用，不需要冠词，第二空后的work是一个不可数名词，同时这里也表示泛指。故B正确。句意：因为现在的失业率很高，对于人们来说找到一份工作很困难。

小题1:去掉the小题2:exact改为exactly小题3:for改为 through小题4:either改为 also小题5:some改为 any小题6:allowed 后面加to小题7:museum改为museums小题8:without改为with小题9:Making改为Make小题10:understood 改为understand 试题分析：文章介绍在公共场所有很多标志。具体介绍了这些标志的含义。小题1:在公共场所有很多标志。词组“in pubic”中间没有冠词：去掉the。小题2:你们知道它们真正的含义吗？exact是形容词修饰名词， exactly修饰动词mean。小题3:你应该在入口进入，通过出口离开。for改为 through“通过”。小题4:在很多电影院，你也会发现很多“no smoking”的标志。Either用于句末， also用于句中。小题5:如果你去博物馆，不要在大厅内拍任何照片。否定句不用some改为 any。小题6:你是不被允许的，be allowed to do…， 后面省略了take photos。小题7:在很多博物馆你会看见很多NO PHOTOS 的标志。Many后面接可输出复数：museum改为museums。小题8:不要在有NO PARKING 标志的地方停车。Without“没有”改为with“有”。小题9:确保你理解这些标志，你就不会有困难。Making改为Make，这是祈使句。小题10:这篇文章是一般现在时：understood 改为understand。

考虑谓语的单复数,看的是主语的单复数,要不然怎么会叫做“主谓一致”呢 此句的主语是Each,所以谓语动词用单数,即 has,或者possesses 用 have 或者possess 就是错的

This exercise is so difficult that few of us can do itThis exercise is too difficult for any one of us to do

答案：A；though虽然；so于是；but但是；or或者；根据句意，“He continues doing it 他继续这样做”和“he meets up with many difficulties他遇到了许多困难”，可知二者之间是转折关系，though引导让步状语从句，意为尽管，虽然；故选A．

All things considered,which do you prefer and why? City-life:fast,furious,fun.Lots of things to do.Lots of people to meet.Endless hustle and bustle.However a probable downside is that it can be noisy,polluted,stressful,unhealthy,and hard to find peace. Town-life:a balance of city and country life.Not too many things to do.Manageable place.Cheaper than a city. Country-life:healthy,quiet living.Very peaceful.Natural views which can be more fulfilling than the sight of skyscrapers and buildings.But very slow,hardly anything to do (unless you have good transport access to a buzzing place nearby),and can be quite expensive sometimes.

更新1: Some say CostLeadership implies + efficency & - flexibility, Differentiation imples flexibily. Is it always correct? If MTR is inflexble in relative to bus, does it implies CostLeadership by providing less stations? What is the differentiation of KMB in relative to MTR? ,Cost leadership and product differentiation in most cases go the opposite way. That me it is not easy for a pany to enjoy lower cost while pursuing a strategy of product differentiation. So &quot;Cost-leadership implies + efficency & - flexibility&quot; is often correct. Cost-leadership generally arises as a result of economies of scale (e.g. by automation so that products can be produced at lower cost, or by sharing administrative costs among several divisions). It is easier to observe the characteristics of cost-leadership in manufacturing industries. If a pany turns to automation to lower its production cost, it will definitely bee subject to certain restricitons in respect to production (e.g. the minimum batch size to achieve cost effectiveness). Products can be produced faster and at lower cost, but the pany loses the flexibility to switch production from one product to another. Product differentiation normally me foing cost effectiveness. One reason is that differentiated products, i.e. those having distinctive features, are not as much demanded as the mon products. Compare sports car like Ferrari with Toyota cars, or PDA phones with the more mon Nokia or Sony Ericson. Company pursuing a strategy of product-differentiation refuse to expand it production line too much to avoid unsold stock.,参考: BBA,cost leadership me you have bigger capacity to cut price. So charging high price is ok. Low price is a kind of differentiation. MTR and KMB both use differentiation. Reasons: To be honest, there is no enough information to support MTR and KMB adopt cost leadership. As their price flexibility is almost none. On the other hand, both MTR and KMB spends money to advertise their difference, eg 多点时间, 多点生活,参考: me,
