副词是有比较级和最高级的，但是也有个别的副词没有的.构成是:1、单音节或双音节的副词的比较级＋er，最高级＋est2、以辅音字母＋y结尾的变y为i＋er或est3、以重读闭音节结尾的，双写最后一个辅音字母＋er或est4、多音节和部分双音节的词需要在形容词原级前＋more构成比较级，＋themost构成最高级你提到的moreeffectively是正确的。再有不明的，可问我。

不算，谓语是has promoted

From an early age we were told that learning is the result of self-discipline. As a consequence, we ought to focus on learning, and have a regular studying habit. And yet the latest scientific research tells us that these may not be a good idea. How to make learning more effective? Benedict Kaili, a famous science journalist in the New York Times", summed up the most up-to-date scientific approach to learning in his new book—— How to Learn . First, we felt we should adhere to a studying habit in the past, but this book says it is not vital. On the contrary, most people get better results because they always change their learning or training places. The more complex your surroundings are, the clearer contents you will learn . Besides, you will remember the contents longer in your mind. Meanwhile, what you will learn won"t depend on your surroundings. And your ultimate goal is to make yourself be able to perform well in any situation. Second, learn to be distracted. Having distractions is obviously wrong when you need to concentrate on your lectures. However,when you encounter a difficult problem, it"s a good method to take a few minutes to rest, surf the Internet and look at the news in order to help you break through the difficult points. The reason is that if you are constantly pay attention to the one problem, then your brain is still in the "offline" state when you are at rest. Even in the subconscious your brain keeps working , but out of the restrictions that make you thinking. Third, a deliberate pause is also a good idea. When you come across a project that involves a lot of mental effort, such as writing a job report, a thesis, etc., don"t postpone it. The sooner you begin doing it, the better it will be. Then let yourself have a rest during the process of doing it and do something else. The book says, while doing the time-consuming and complicated task, breaking in from time to time will make your brain to "activate" the subject, and let you start to see and hear anything relating to this subject in daily life. Apart from this ,it can let you be more sensitive and pay attention to those scattered information surrounded by you. 从小就有人告诉我们，学习是一个自律的结果，要专注，要有一个有规律的学习习惯。但是最新的科学研究成果告诉我们，这些未必是好办法。那如何才能让学习更有效呢？《纽约时报》顶级科学记者本尼迪克特u2022凯里在自己的新书《如何学习》里面，总结了关于学习的最前沿的科学方法。 第一点，过去我们觉得要坚持一种学习习惯，但这本书里说，这并不重要，大多数人反而会因为总是变换学习或训练场所而获得更好的效果。你练习时的周遭环境越是复杂多变，你学的内容就越能记得清楚、长久，同时你学到的东西就越不会依赖于周围的环境条件。而你的最终目的，是要让自己在任何环境中都能发挥出色。 第二点，学习要学会“分心”。当你需要集中注意力听课时，分心显然不对。但当你遇到某个难题的时候，花几分钟休息一下，上上网，看看新闻，这是一个能帮你突破难点的好办法。因为如果你真的一心惦记着某个难题，那么在休息的时候，大脑仍然会在“离线”状态下、在潜意识中继续运转，而且是跳出了那些让你受到限制的思路。 第三点，刻意停顿也是一种好办法。当你遇到某个很耗费脑力的课题时，比如写工作报告、毕业论文等，不要往后推延，越早开始越好；然后中途让自己停顿一下,去做做别的事情。书里说，把耗时而复杂的任务时不时地中断一下，会在你的大脑中“激活”这个课题，让你开始能看到、听到日常生活中任何与这个课题有关的事物,同时也会让你对周遭这些零零散散的信息更为敏感和关注。

承担更多的工作量并不会让你获得晋升，相反，可能会凸显你没有能力分配好工作。

真的么？教室里有什么？

你说的对啊,这里这个被动其实已经变成了分词+介词短语,跟在seem后面构成表语,相当于形容词,是很典型的主系表结构,主系表这种基本句子结构中,谓语就是系动词,所以done即使是被动语态,也不当动词用了.

effectively: 有效的，能产生预期效果的，例子：Services need to be more effectively organized than they are at present. 服务的管理应该比现在更加有效。efficiently: 效率高的，效能高的，例子：I work very efficiently and am decisive, and accurate in my judgement.我工作非常有效率，处事果断，而且判断准确。这两个的区别很明显，前者就是有效的，产生效果，后者则是效率高，不光有效率，而且效率高。前者强调某物或者某事达到预期的期望，后者强调完成一件事情省时省力，效率很高。这些就是它们用法上的区别。

这两个词根本就没有联系，前面是有效地；后面的是有影响地

Developing good communication skills is an important part of living a fulfilled life. Effectively communicating your career, personal, and everyday needs in a way that comes across clearly, persuasively, and thoughtfully is crucial; and yet, not everyone knows how. It isn"t innate, and many bright, talented, and dedicated people don"t get where they should, all because they fail to adequately communicate their point.Don"t let that be your fate. No matter what your age, background, or experience, effective communication is a skill you can learn (no matter how you might feel about it now). With a little self-confidence and knowledge of the basics of good communications, you will be able to effectively communicate your message in both conversations and presentations, in all walks of life.

学习任何语言，都要从实战和心理两个方面做好准备。学英语的实战方法，具体到各个环节有很多，需要你结合实际的努力自己来发现、总结和运用。现在我想说说最重要的学习方法，就是读。读，从两个角度来读。1、读没有翻译的原文。读，懂不懂无所谓，就是读，这是培养语感。当你读了很多原文后，你都不用想就会脱口而出正确的词句来。2、读有翻译的文章。这时候你要多花时间对译来读。一般我先看汉语，自己翻译一下，然后看英语，再回头对比自己哪里翻译的不对。这样做的时候会明显感觉到对自己的中国式英语思维，和词汇的贫乏。对比后立刻记住了，效果很好，比你单独背语法背词汇收获大多了。这样练习久了，水平提高很快的。学英语不用一开始就一定要精准，一定背记下来，一定要弄明白，这样学起来很累，效果不见得多好。就是大量的阅读，类似囫囵吞枣，大量看对译，（对译的时候别忘了经过自己头脑的转换和对比），只要阅读量够，你的语言水平会让你大吃一惊的。学英语的心理战术1、让自己爱上英语。可以从假爱到真爱。就是面对着复杂的英语你也要对自己说：“我真喜欢英语啊”，“英语真好学啊” ，“英语真好听啊”，心理暗示久了，就真爱上了。2、让自己进入英语文化背景中。我在自学韩语，我教的韩国学生团结、守纪律、有礼貌，坚毅；我看的韩剧唯美、含蓄、幽默，我想知道这些品质是怎么来的，或者说我也想变成这样的人，那么就从语言入手，说这种话的人就会被熏染这种语言文化。所以我开始学习，经历了艰难的开头，焦虑畏难之后，慢慢自己能读完整了，再去听听他们怎么说，突然有一天，早上起来就想张口说韩语，不说出来不舒服。以此类推，你去看看英语的电影电视剧，听听英语歌曲。3、学英语不要怕。学英语不要怕。入门时，如果方便可以找个入门班，然后可以自学。先找到简单的英语文章，和简单的英汉对译文章，让自己很快获得心理满足和成功的感觉，再逐步增加难度。学英语不要怕，还是老话，天下无难事，只怕有心人。当你听、看、说英语到一定程度，你就会习惯这种语言，你就会被这种语言浸染，不冲口说说，就心里憋闷，口中无味了。好，就聊到这儿，祝你成功！相信你会成功！

大学英语四六级开考在即，在备考过程中，想必各位同学也非常想知道学习英语的技巧和方法。下面我为大家详细盘点一下相关信息，供大家参考。 学习英语的基本方法 坚持听说训练 ①每天都要坚持听英语磁带并跟着朗读。哪怕每天20分钟也行，关键是要养成每天坚持练习的习惯。这种习惯养成以后能使自己的英语学习终生受益。 ②每天坚持背诵单词。英语单词量的深度和广度是外语学习成绩好坏的一个标志，掌握大量的单词非常有助于外语的学习。 ③每天坚持听英语广播几分钟，以便熟习语感。听英语广播也有助于学习语法知识。 ④尽可能“心译”接触到的英语。如一闪而过的广告，偶尔听到的短语或话语等。 ⑤勇敢地说外语，不要害怕出错。学习外语还要勇于请别人纠正，不要难为情，更不要泄气。 书面表达 每天一篇短文阅读，每周一篇书面表达。可以阅读一些浅显的英文刊物，像《21 st century》等。书面表达可以写自己身边发生的生活小事，单词不熟悉可以通过查字典来解决。 用英语写日记 哪怕只写一两句心里想说的话或几个单词也可以。写日记就像走进大自然一样，也是开启心灵的灵丹妙药，它一旦被养成习惯，就会成为我们学习外语的好朋友。 四六级备考技巧 备考攻略一：听力记得用所能想到的技巧。我们听听力的时候，想要在短时间内提高听力分数，就必须要用上技巧。用尽你脑中能够想到的方法。举个例子，听录音的时候，要养成先看题目的习惯，记住提前看。并且准备好笔，画关键词。第二步在播放录音的时候，心无杂念，带着选项关键词去听。听对话时把信息点略记下来。第三步确定答案的时候，根据关键词和你速记信息选择出符合问题的答案。这里还有个技巧就是听到提问时及时记录，有助于选出正确答案。 备考攻略二：阅读理解找中关键词和主旨句，记住看文章内容一定要带着英语思维去看。这九天时间做好阅读单词选项的积累，背单词工作不要停，能够掌握多一个单词就是一种进步，这段期间尽量把四六级要求背诵词汇重新温习一遍。做题找准关键词句，然后带着关键词回到文章中去，接着根据文章大意确定最终答案。 备考攻略三：翻译题运用平时背诵的词汇、高级句式。在汉译英过程中我们要积极调动脑中积累的英语词汇，先把主谓宾一一列出，再添加其它成分变为长句。翻译的时候如果实在不会写长句，那就用简单句表达，我们的原则是能够拿多少分就尽量拿分。
