英语学科整改措施
一、关于作业：
精心选编作业，题量适当，针对学生的学情分层布置，指导学生认真、独立完成作业；作业批改、反馈应及时，可适当结合面批，做到表扬鼓励和严格要求相给合，使学生养成良好的作业习惯；作业评定可采用等级、语言评价等多种形式；作业形式要多样化，应采用口头与书面、课内与课外相结合的方式，应加强实践性作业布置的探索与实践；
三、四年级课外作业以磁带跟读、听说模仿、录音作业为主，
五、六年级在听说朗读的基础上，加强读写练习。
二、关于单词：
单词教学是英语教学的基础，也是提高英语成绩的关键。要紧紧围绕一个核心重点来学，那就是学“语音认字”，说得简单点，就是围绕“音”来学习，学习英语的发音和单词记忆原理。三年级作为英语教学的起始年级，首先要把26个字母教会，不要怕教26个字母会与汉语拼音混。关键不看他是否能写出单词的26个字母，而要看他是否能把26
个字母里所记录的声音用嘴巴准确地再现出来、发出来，再现得越准确，他就越认识了这个单词，再现得越不准，他就越不认识这个单词。其他年级的要求课上老师必须教认读单词，按音标分解单词教认读，当堂书写加强记忆，课后布置抄写，下一节课进行默写。做到一课一默。
三、关于课文：
英语课文的记忆是学好英语的重点，要求学生把每课课文中和对话进行背诵，发挥小干部的作用，做到有布置、有检查。重点句型要求默写。
具体措施：
()1、教导处对班级每周进行抽查，每次四个年级各一个班，内容是每课的蓝单、短语或句型。
2、全体英语教师每周开展教研活动，时间暂定周五4:30，要求每一位英语老师说说本周自己教了哪些单词和短语，然后周一下午第二节课抽测。
3、英语作业和单元练习卷一定要求学生独立完成，作业允许出错误，但回批要及时。
4、英语课上要求每节课必须有5分钟默单词时间，5分钟听录音时间。
5、加强培优补差力度，尤其重视后进生的鼓励和检查，正去在原有基础之上能有所进步。

利用固定化过氧化氢酶回收纺织品漂染的废水 Silgia A. Costa1, Tzanko Tzanov1, Filipa Carneiro1, Georg M. Gübitz2 &Artur Cavaco-Paulo1,? 1纺织工程系, 米尼奥大学, 4810吉马尔, 葡萄牙 2环境生物技术系, 格拉茨技术大学, 8010格拉茨, 奥地利 ?作者联系方式(Fax: +351 253 510293; E-mail: artur@det.uminho.pt) 关键词：过氧化氢酶的固定化，酶稳定，过氧化氢，纺织印染 摘要 过氧化氢酶固定在氧化铝载体上并用戊二醛交联，在再循环塔反应器和CSTR反应器中研究贮存稳定性，温度和pH值对酶的活性。固定化酶的在的活性维持在44％，pH值11（30?C），对照组是活性为90％，pH值7（80?C），过氧化氢酶固定化的半衰期时间被提高到2小时（pH12，60?C）。用过氧化氢漂白织物后，洗涤过程中的残留水被固定化酶处理，可以用于再次印染时，记录实验数据。 1 序言 由于新的法规的出台，从生态经济的角度来看（Dickinson1984年），对于纺织行业中存在的成本和剩余水域的污染问题，必须给予更多的关注。过氧化氢是一种漂白剂，广泛应用于工业纺织工艺（Spiro & Griffith1997年）。在去除H2O2时，会消耗大量的水和能源（Weck 1991, St?hr & Petry 1995），以避免对氧气敏感的染料（Jensen 2000）产生后续问题。过氧化氢酶可用于降低过氧化氢的含量（Vasudevan & Thakur 1994, Emerson et al. 1996），从而减少水分消耗或方便回收印染洗涤液。过氧化氢酶的使用主要问题出在漂白时温度和清洗液碱度过高。以前，我们试图通过筛选新的嗜热嗜碱的微生物（Paar et al. 2001）或使用不同的酶稳定剂（Costa et al. 2001）来解决此问题。但是染料与蛋白质之间的潜在相互作用（Tzanov et al. 2001a, b）表明，可溶性过氧化氢酶的使用是不恰当的。固定化过氧化氢酶的使用还有一种选择(Costa et al. 2001, Amar et al. 2000)。在这项研究中，我们对氧化铝进行共价固定并使用戊二醛作为交联剂，这种方法在商业中得到验证。本项研究的目的就是探讨过氧化氢酶的固定化动力学，及其稳定性和工艺条件，这将使我们能够应用此系统，以处理可能被用于清洗染色的反复使用的酒。 2 材料和方法 2.1 酶 Terminox（EC1.11.1.6），50L以上，由AQUITEX- Maia提供，葡萄牙产。 2.2 过氧化氢酶的固定化 取Al2O3颗粒或薄片（Aldrich），直径分别为3和7毫米，在45摄氏度下，先经浓度4%的γ-氨丙基三乙氧基硅烷(Sigma)烷基化，再放入丙酮中浸泡24小时。用蒸馏水洗涤硅烷化载体后，放入浓度为2％戊二醛水溶液中室温下浸泡2小时（Aldrich），重复清洗一次并在60?C下干燥1小时。取五克的烷基化载体，室温24?C下浸泡在25毫升粗酶制剂中（Costa et al. 2001）。得出，每克Al2O3

Friends or 'Enemies?' When I was younger, my Dad used to tell me: "Boys don't want to be your friend." He then left the rest to my imagination. At the time, I didn't agree. I thought: I can crack a good joke, I know how to shoot a hoop, and I'm a cheerful person (but not in an annoying way). What kind of boy wouldn't want to be around that kind of girl? Turns out, my Dad was right. Not to be all "Samantha Brick" about it, but in my experience, single, heterosexual men aren't actively looking for an exclusively platonic relationship with a woman they find sexually attractive. This of course is not a revolutionary concept. In fact, it seems pretty natural to me. Now, I will be the first to say that it is really and truly the most wonderful thing in the world if the attraction is mutual. But the Powers That Be seem to like to play these complicated little mating games with humans where the guy we want to re-enact scenes from 9? Weeks with sees our attractiveness level as akin to that of a discarded dishcloth, and the most physical we could see ourselves being with the guy who actually likes us is a game of ping pong over an especially long table. All of which means that someone usually ends up getting rejected. I'm sure I'm not alone when I say I have struggled with the scenario where I am not interested in a man romantically, but I want to keep him as a friend because he is funny and I enjoy his company, or he has shown himself to be that rare specimen known as "a nice, genuine person, " or he simply doesn't mention his therapist in every other sentence. Rather than string him along and give him hope, I feel compelled to somehow communicate to him sooner rather than later that we'll just be staying friends, nothing more. Otherwise, I think I am being unfair to him. Why should he waste his romantic stamina on me when there are loads of other single women out there who might fall instantly in love with him? The thing is, it can sometimes be tricky to reject a man and keep him as a friend. If the operation is not executed carefully, you may end up creating a "menemy." It requires a certain amount of skill to be able to turn down a man's sexual advances or romantic gestures and then get him to agree to meet you for blueberry pancakes the following weekend and chat about the latest Woody Allen film. Some men aren't satisfied with just that. I'm not clear why. What's so bad about friendship? Everyone needs buddies. But I've seen men react poorly or simply fall off the face of the earth. I get it -- their feelings are hurt. None of us likes getting rejected. But in my experience, some men find it especially soul-crushing. I am only bringing all of this up because I recently had to go through this scenario again. I had spent some time cultivating a friendship with a man who, in my defense, I thought was gay. So I didn't see the harm in him buying me the occasional falafel, or accepting an invitation to see a film with him. Isn't that what friends are for? But a mutual friend shed light on his sexual orientation (straight) and suggested that his intentions -- and attentions -- weren't platonic. He had never "made the moves" but now it was all crystal clear -- that explains the way he had looked at me that time the tahini sauce dribbled down my chin! Since he had clearly been too timid to express his feelings, I thought I would be clever this time and subtly mention the dates I had been going on, focusing on the one guy I was kind of keen on, so that he would know that I was "unavailable" for heavy petting and those sorts of activities, but that I was available for things like roller skating, falafel-eating and shooting the breeze. Doesn't that sound nice? That way, he would known not to try to lean in for a kiss, and I wouldn't have to pull the Stevie Wonder dance and dodge him went he went for it. It was like pre-rejection, yet I was sparing his feelings because he didn't even have to put himself out there! I really thought I was being brilliant. It backfired, of course. Said man ended up sending me an email rant accusing me of being insensitive by talking about other men when he had "feelings for me." As if I am psychic, by the way, just because I am a woman! How was I supposed to know that? I think in his mind we were dating. In my mind, he was my new gay BFF. In the end, I got mad at him for getting mad at me, and now the friendship has ended. And I have created yet another "menemy." Look, I have also tried the direct thing: "I really like you, but only as a friend, " but you can only do that when the guy has made his intentions clear, and in my experience, they either cope okay (though rarely do I feel much enthusiasm for friendship after that), or they really don't cope well. I also tried the thing where you make them think they are rejecting you, but it gets quite confusing and only works if the guy isn't very sharp, and why would I -- or you -- be hanging out with someone not that sharp in the first place? As we all remember, Billy Crystal's character says men and women can't be friends in When Harry Met Sally because the sex stuff gets in the way. I do have single, male, heterosexual friends with whom I have an easy, non-romantic rapport, but I honestly don't know if they would walk away if I was sprawled naked on a bed calling out to them. I may not be everybody's cup of tea, but sometimes, I wonder if they wonder. And they may wonder if I wonder. If so, I hope they'll keep it to

附录A Introduction to database information management system The database is stored together a collection of the relevant data, the data is structured, non-harmful or unnecessary redundancy, and for a variety of application services, data storage independent of the use of its procedures, insert new data on the database, revised, and the original data can be retrieved by a common and can be controlled manner. When a system in the structure of a number of entirely separate from the database, the system includes a "database collection". Database management system is a manipulation and large-scale database management software is being used to set up, use and maintenance of the database. Its unified database management and control so as to ensure database security and integrity. Database management system users access data in the database, the database administrator through Database management system database maintenance work. It provides a variety of functions, allows multiple applications and users use different methods at the same time or different time to build, modify, and asked whether the database. It allows users to easily manipulate data definition and maintenance of data security and integrity, as well as the multi-user concurrency control and the restoration of the database. Using the database can bring many benefits: such as reducing data redundancy, thus saving the data storage space; to achieve full sharing of data resources, and so on. In addition, the database technology also provides users with a very simple means to enable users to easily use the preparation of the database applications. Especially in recent years introduced micro-computer relational database management system , intuitive operation, the use of flexible, convenient programming environment to extensive (generally 16 machine, such as IBM / PC / XT, China Great Wall 0520, and other species can run software), data-processing capacity strong.

(Reports on Britain Under the Bombs) Night after night, in the hot summer and early fall of 1940, a deep, steady voice came over the Atlantic Ocean from England to America, telling of England's battle for survival under the waves of German bombers. This strong and steady voice, an American voice with a slight accent of North Carolina, belonged to Edward R. Murrow, head of the European staff of the Columbia Broadcasting System. "This is London," said Murrow, while the bombs fell and flames spread on the streets of the city. His voice had a tone of sorrow for the suffering of that ancient city, and a tone of confidence, too -- a feeling of belief that London would be there, no matter what it had to endure. It could not be destroyed. The heavy raids began in the middle of August, and Nazi bombs started to fall along England's Channel Coast. The German bombers cast dark shadows over the white cliffs of Dover, and England's Home Guard prepared to fight on the beaches, on the cliffs, and in the hills, until the last Englishman died or the invaders were driven off. Air Marshal Goering's bomber pilots were sure of their ultimate triumph over England. Hitler and Goering believed that when London became a burned city like Warsaw and Rotterdam, England would surrender. But the English were more fortunate than the Poles in Warsaw and the Dutch in Rotterdam. They had the English Channel as a barrier against the Nazi ground forces, and they had the Royal Air Force(RAF) to battle the Nazis in the sky. The hardships of London really started in the first week of September, when Hitler was at last convinced that the English did not intend to give in. On September 7, 1940, nearly four hundred German bombers hammered the city with bombs in broad daylight. Marshal Goering boasted, "This is the historic hour when our air force for the first time delivered its bombs right into the enemy's heart." Fires burned, houses fell, gas pipes burst, and dark smoke rose from the streets. Men, women, and children felt the effect of the bombs. Radar sirens wailed, ambulances rushed from one place of agony to another, and fire fighters faced the flames hour after hour.
步进电机的知识 什么是步进电机： 步进电机是一种把电脉冲转化为角位移的执行机构。通俗的说：当驱动程序收到一个步进脉冲信号，将驱动步进电机轴旋转一个固定的角度（步进角）。您可以通过控制脉冲个数来控制角位移，从而达到准确定位的目的;同时，你可以通过控制脉冲频率来控制电机的旋转速度和加速度，实现速度控制的目的。 步进电机的种类： 步进电机分为三种：永磁式（PM），反应式（VR）和混合式（HR）永磁式步进电机一般为两相，转矩和体积较小，步进角一步7.5度或15度;反应式一般有三相可以实现大转矩输出，步进角一般是1.5度，但噪声和振动大。在欧洲和美洲80个国家已被淘汰;混合式步进是混合了永磁式和反应的优势。它由两相和五相：一般两相的步距角是1.8度，而的五相步距角为0.72度。是使用最广泛的的步进电机。 步进电机允许的最高表面温度 步进电机温度过高首先会的磁性材料退磁，导致转矩降低甚至失步，电机表面温度允许的最大值取决于的磁性材料退磁点;一般来说，磁性材料退磁点在摄氏130度以上有些材料甚至高达摄氏200度高，所以步进电机表面温度在摄氏80-90度是正常的。 步进电机精度为多少？是否累积 一般步进电机的精度为步进角的3-5%，且不累积 如何确定步进电机驱动器直流电源 A.电压确定 混合式步进电机驱动器的电源电压范围较广（比如IM483的供电电压12?48VDC），电源电压通常根据电机的转速和响应要求来选择。如果要求较快的运行速度较高的响应速度就选用较高的电压，但注意电源电压的峰值不能超过驱动器的最大输入电压，否则可能会损坏驱动器。 B.电流确定 电源电流一般根据输出相电流I来确定。如果采用线性电源，电源电流一般可取I的1.1?1.3倍;如果采用开关电源，电源电流一般可取I的1.5?2.0倍。 步进电机的主要特性 在步进电机关机时要确保没有脉冲信号，当电机运行时 如果加入适当的脉冲信号，它会转过一定的角度（称为步距角是）。转速与脉冲频率成正比。 2龙式步进电机步距角7.5度，旋转360度，需要48个脉冲来完成。 3步进电机具有快速启动和停止的优良特性。 4只要改变脉冲，可以很容易地改变电机轴旋转的方向。 因此，目前的打印机，绘图仪，机器人设备以步进电机作为动力核心。 步进电机控制的例子 我们以四相单极步进电机为例： 四个相绕组引出四个相和两个公共线（连接到正极）。一相接地。会被激发，。我们使用四相八拍控制，即第1阶段第2阶段交替反过来，会提高分辨率。步距角0.9°，可以转移到控制电机励磁是为了转移如下： 如果电机反转的要求，传输的激励信号可以逆转的。2控制方案 控制系统框图如下
