商务写作指南：超好记的appreciate的用法
WRONG: We would appreciate if you corrected the entry in the register as soon as possible. 错误用法：如果你能尽快更改登记处的入口，我将非常感激。 RIGHT: We would appreciate it if you corrected the entry in the register as soon as possible. 正确用法：如果你能尽快更改登记处的入口，我将非常感激（英语原句比前者多了一个it）。This is a very common mistake, and remember that when you use the phrase “I would appreciat e…”you MUST include the word “it”before “if”: 这是一个常见错误，记住当你要用“I would appreciate…”这个表达式时，一定要在if前加一个it。 More examples: 更多例子： E.g.1:I am sure the supervisory authority would not appreciate it if you took that course of action. 例1：我相信监督部门对你的所作所为不会表示欣赏。 E.g.2:We would appreciate it if you would arrange for immediate payment. 例2：如果您能立即付款，我们将很感激。 There is no need to add “it”if you do not include “if”. 如果你不用if从句的话，就没有必要在appreciate后面加it了。 E.g.: We would much appreciate a letter informing us of the result of your enquiries. 例句：如果您能对您的询盘结果给我们回信的话，我们将非常感激。 An alternative phrase to “I would appreciate it if…”is, “I would be grateful if…”This is the more formal phrase of the two and does not require that troublesome“it”! “I would appreciate it if…”这个表达式的替代用法有“I would be grateful if…”，但是这个用法更为正式，而且不需要加那个麻烦的“it”！
英语语法专项：动名词用法讲解及练习(附答案)
你听过英文语法有动词(verb)、名词(noun)；但你听过有动名词(gerund)吗？ 1. The girl is singing a song. 2. The girl singing now is my sister. 3. Singing is one of her hobbies(爱好). 三个句子中都有singing。第一个句子的singing是常见的现在进行式(Present Continuous)，是说眼下正在做什么；第二个句子的singing是现在分词(Present Participle)，它把sing这个动词转为形容词，但仍有动词的成份（哈哈，这么一说，要把你搞晕了吧:-) 。关于分词，以后有空再谈OK？）。好戏在后头，你看看第三个句子的singing到底是什么东东呀？原来就是我们的主角动名词(Gerund)了！憧矗瑂ing原本是个动词，可是现在它加上ing后，看来竟像是一个名词了。 一、名词性的动名词(Nominal Gerund) Nominal Gerund 可以加上定冠词(Definite article，如the)或不定冠词(Indefinite article，如a, an)，其他可加在动名词前的还有如：my, this, some, any, all, no 等等。举例如下： 1. The mellow(愉快地) singing of the birds announces the coming of spring. (singing前加定冠词the及形容词mellow；coming 前加the) 2. We knew the robber was near when we heard a faint rustling(沙沙声) in the bushes. (rustling 前加不定冠词a及形容词faint) 从上面的例子可看出如何将一个动词转成名词；但它和真正的名词还是有区别的，那就是没有单数或复数之分。不过，有一些动名词是可以变成真正名词的喔，如：saying, writing, opening, painting, cutting, heading, feeling, being,saving, surrounding, crossing, misunderstanding 等等。它们都可以有复数的喔，方法就是在它们的后面加个s，如：paintings。 二、动词性的动名词(Verbal Gerund) 看看下面的句子： Carelessly writing essays annoys the teacher. 上面的句子里的writing是动名词，但前面有副词carelessly（粗心地），后面又有受词(Object) essays。因此writing就有动词的特征。 注意：Verbal Gerund 这类动名词的前面可不能加上任何冠词(the, a, an ...)喔。 动名词的功能与用法 一、在句子中用作主语(Subject)或主语的补语(Subject Complement): 1.1 作主语 1. Listening to music gives me pleasure. (主语Listening ） 2. Running is good exercise. （主语running) 3. Walking to school is a good idea. (主语walking) 1.2 作主语的补语 1. My cat's favorite activity is sleeping. (补语sleeping) 2. Seeing is believing. (主语seeing, 补语believing) 1.3 主语置于句尾 1.3.1 用It + be + ... +v-ing 句型 1. It is fun speaking English. 2. It is of great importance fighting against pollution(污染).

appreciate表示感谢的用法
外教一对一https://www.360docs.net/doc/fa10989074.html, 用appreciate表示「感谢」，用对不容易 在邮件里表示「感谢」的时候，我们常常会用到appreciate一词;在比较正式的场合，你也会偶尔听到有英美人在口语中使用appreciate 来表示「感谢」的含义。本帖将教会大家如何用对appreciate一词。1)表示感谢的时候，appreciate的对象通常不是某人，而是某件事。 和动词thank不一样的地方在于：thank 后面常常是某人。比如：Thank you for doing sth。但是appreciate后面常常是某件事，比如：I really appreciate your help. 很感谢你的帮助。Your support is greatly appreciated. 很感谢你的支持。以上的两个例句，通常都用在帮助或者支持完成之后说。而下面的这句话，是我们邮件中最常用的句式：I would appreciate it if you paid in cash. 如果你用现金支付，我会非常感谢。这个邮件的高频句式其实很容易出错，注意以下三点：appreciate后面的it不能漏掉appreciate后面不能直接加you以上面的句子为例，主句里的would和从句里的paid使用了过去式，是为了让语气更加婉转，而非表达过去的含义。I will appreciate it if...do...这样的句式也正确。2)中文里可以「欣赏」某人的品质;appreciate也一样。 中文里「欣赏」一词有两层含义：领略欣赏。比如：欣赏一段音乐认为……好。比如：老板很欣赏他的才华。巧合的是，appreciate 也有这两层含义：领略欣赏。You can't fully appreciate foreign literature in translation. 看翻译作品很难欣赏到外国文学的精髓。认为……好。His talents are not fully appreciated in that company. 在那个公司，他的才能得到充分地赏识。丨There's no point buying him expensive wines - he doesn't appreciate them. 别给他买很贵的酒，他不懂得品赏。3)appreciate还有一层生僻的含义：增值 我们会在财经新闻里看到appreciate及其反义词depreciate，分别表示「增值」和「贬值」。Their investments have appreciated over the years. 他们的投资在几年间增值了。currency depreciation 货币贬值 文章来源：https://www.360docs.net/doc/fa10989074.html,
现在完成时的用法解析
Lead in 一般过去时导入：一般过去时的概念 一般过去时表示过去某个时间发生的动作或存在的状态。 I lost my pen.(过去时) I have lost my pen.（现在完成时） 过去时一般表示过去所发生的动作或存在的状态。“我把笔丢了”，说话人只是想告诉对方在过去的某一个时间里他的笔丢了，仅此而已。（仅仅是在陈诉过去的一个事实，与现在没有关系） New lesson 一．现在完成时的构成： 助动词have/has(not) +动词过去分词 She has turned on the lights. 肯定式：have/ has+过去分词 否定式：haven’t/hasn’t+过去分词 疑问式：把have/has 提到主语前面 肯定回答：Yes,…have/has 否定回答：No,…..haven’t/hasn’t 二．用法 1.表示过去发生的动作对现在造成的影响或结果. 例如:She has gone. 她走了. She went in the past.(She is not here
now.) I have just cleaned my hands. 我刚洗过手。（“洗手”是发生在过去的动作，对现在造成的结果是“手干净了”） I have closed the door. (The door is close now.) She has turned on the lights. (The lights are on now.) He has written his name on the blackboard. (The name is on the blackboard now.) Mother has cooked the dinner. (We can have dinner now.) You have seen the film. （You know what the film is about.) We have cleaned the classroom. (The classroom is clean now.) 2. 表示动作发生在过去，并且一直延续到现在，甚至还可能继续延续下去。这时常和since所引导的短语或从句或for引导的短语连用(for有时可以省去)。以及so far, by now, these days, in the last/past … years/days…等连用。 I have lived here for over ten years. （表示他现在还在这里居住，并且还有可能继续住下去）比较：I lived here ten years ago.(仅仅说明了他十年前在这里记住过的事实,不代表现在他还住在这里) He has studied here since 2006. 都用How long 提问，例： We have learned English for three years. We have learned English since three years ago.

英语词汇正误辨析 arouse正误用法
英语词汇正误辨析arouse正误用法 ■这本书引起了我对政治的兴趣。 误：The book aroused at my interest in politics. 正：The book aroused my interest in politics. 析：arouse(引起，激起，唤起)是及物动词，其后接宾语时，无需用任何介词。顺便说一句：arouse 的宾语通常兴趣、怀疑、愤怒、同情、批评、讨论等较抽象的东西。 ■演讲者激起了听众的愤怒。 误：The speaker aroused the audience with anger. 正：The speaker aroused the audience to anger. 析：表示激励或唤起某人做某事，通常用arouse sb to sth，注意通常用介词to，其实此句也可说成：The speaker arousedthe anger of the audience.又如：He tried to arouse her to action.(他试图要使她采取行动)。 ■能再次收到你的来信, 我们将十分感激。 误：We shall appreciate to hear from you again. 正：We shall appreciate hearing from you again. 析：appreciate(感激)后接动词时，要用动名词，不用不定式。 ■谢谢你的好意。 误：I appreciate you for your kindness.
正：I appreciate your kindness. 正：Thank you for your kindness. 析：其后只能接“事”作宾语，而不能接“人”作宾语，此用法与thank 的用法恰恰相反。 ■如果你能帮助我做这事，我将十分感激。 误：I would appreciate very much if you would help me with it. 正：I would appreciate it very much if you would help me with it. 析：appreciate(感激)是及物动词，其后不能没有宾语。另外也有的词书(如《朗文当代英语词典》)将I would appreciate it if...视为一个固定句型。另外有时其中的if从句也可能换成when从句。如：We really appreciate it when she offered to help.(她来帮忙了，我们十分感激)。

Language, diction (to solve the meanings of the words and syntactic structure) 5. Musical and sound effects 6. Theme (subject matter) and tone Appreciating Sonnet 18 Shakespearean sonnets collections contains 154 sonnets, commonly thought to be written between 1593 and 1599, which may be roughly divided into three groups. 1. Numbers 1-17 are variations on one theme. 2. Numbers 18-126 are on a variety of themes associated with a handsome young man. 3. After that, began a new series, principally about a married woman with dark hair and complexion, the so-called “dark lady of the sonnets”. 赏析 It is written in iambic pentameter rhymed abab cdcd efef gg. (3 quatrains, 1 couplet) Shall I /compare/ thee to/ a summ/er’s day?/ Thou art/ more lo/vely and/ more tem/perate:/ Rough winds/ do shake/ the dar/ling buds /of May,/ And sum/er’s lease/ hath all/ too short/ a date:/ 2.

Lease: duration; the eye of heaven: the sun; complexion: appearance; Fair (the first): beautiful appearance; fair (second): beauty . Theme: Lines endows one’s beauty with immortality. 6. Shakespeare deals with the traditional themes of time, beauty and poetry and expresses his feelings towards the addressee. The poem is a comparison between the man’s eternal beauty with summer’s temporal beauty, between the inconstancy of nature and the timelessness of poetry. Shakespeare poses the idea that through poetry, beauty gains immortality. This image of transience and eternity is used throughout the poem. More reflections: the theme of homosexual (internet information) Analysis of Sonnet 18 Shakespeare’s sonnets, though they are well with the general tradition of Elizabethan sonnet cycles, are in several ways unique. The principle person addressed by the poet is not a woman but a young man; the dark lady, when she appears, is vastly different from the convention. More important, the depths of moral and aesthetic contemplation in Shakespeare’s sonnets are far more profound than we find in other Elizabethan cycle. With 3 exceptions (99, 126 and 154)Shakespeare uses the sonnet in popular English form, first fully developed by Shakespeare varies it. The couplet usually ties the sonnet to one of the general themes of the series, leaving the quatrains free to
