idiom

About idiomI. IntroductionIdioms include metaphorical phrases, slang, proverbs, allusions and habitual collocations, etc. The fixed phrases and short sentences always belong to this type; they become daily expressions gradually and are used quite often. Whether in grammar structures or collocations, idioms have their own usage, the connotations and the structures cannot be changed arbitrarily by the language users. Idioms are concise in structures and deeply philosophical in meanings. As a special form of the language, idioms have close relationship with customs and geographical environments; connect with historical backgrounds, economic life, religious beliefs, and social values. Like a mirror, idioms reflect the cultural features of the language.In English-speaking countries, idioms are heard and read everywhere from debates to everyday conversations .A good mastery of idioms becomes a significant symbol of a person’s command of the language. However, because of a low level of linguistic competence in the target language, people who learn English as a second language are at a distinct disadvantage in understanding English idioms. We must know the origins of English idioms so that we can learn English well.Idioms as a special form of language carried a large amount of cultural information, such as history, geography, religion, custom, nationality, psychology, thought pattern and so on, and therefore are closely related to culture. They are the heritage of history and the product of cultural evolvement. General speaking, English idioms came from society, culture and history; they included in everything and related to our society’s life and played an important role in culture. In this paper, I’m going to show the sources of English idioms, and then make a contrast between Chinese and English idioms, finding their differences and similarities in culture. In this way, we can easily study and understand English idioms for successful communication. To sum up, it is important to study English idioms, it is also necessary.II. The sourcesA. Idioms from living circumstanceLanguage is a reflection of one country’s cultural background. The natural environment including geographical position, climate, and ecological condition is something that plays contributory role in the formation of language. Certainly, their special way of living, thinking and behaving is formed as a side-product of their relationship with the environment.Idioms are closely related to people’s labor and life, people in particular culture need words to name and explain objects in their culture. Because Britain is an island country, people who live along seacoast and whose livelihood is dependent on the sea will have idioms about water, sailing, island and fish. For example, “to take the wind out of somebody’s sail”(先发制人) ,“at sea”(茫然), “to trim one’s sail to the wind”(见风使舵),“never offer to teach fish to swim”(不要班门弄斧),“full fish”(乏味的人),“sail under false colors”(欺世盗名)(庄和诚，2002. P572),etc. What’s more, climate, agriculture are also another factor in the living condition. While Britain is located in western hemisphere, with North T emperate Zone and marine climate, so “west wind” is the symbol of spring. The west wind blows from the Atlantic Ocean is warm and gentle, so that Britain abounds in rain can be proved in some idioms concerning rain: “to make hay while the sun shines”(趁热打铁), “to rain or shine”(无论如何), “rainy day”(穷困时期), “as right as rain”(非常正确)etc.The British people are good at hunting and fishing; they often use horses working in the field, so they made their way of life and made of production. There are many idioms from agriculture. E.g ,“beat around/about the bush”(拐弯抹角)(高凌，2002.10. p43)this from hunting, “a hard row to hoe”(难办的事情), “have all one’s eggs in one basket”(孤注一投), “put out to grass”(年老退休), “ride on the high horse”(盛气凌人), “feel like a fish out of water”(感到不自在).B．Idioms from religions and beliefsAs a cultural phenomenon, religion, which is the manifestation of cultures, is the vital part of human thought .Religion is an important source for idioms. Most of westerners are Christians, who believe that the world was created by God. They think that God is omnipotent and sacred. God, Christ, devil, Adam and some educational segments of the stories in Bible are passed down, because of people’s favor or even some historical and political causes, especially religious beliefs. Many British who believe in Christianity all read the Bible; therefore, numerous idioms have come into people’s colloquial speech, and have become mottoes. For example: “Judas’s kiss”(犹大之吻) from the Matthew, Judas, one of the Twelve, agrees to betray Jesus that the chief Priests counted out for him only thirty silver coins. A kiss as the betrayer had arranged a signal with the chief Priests. Jesus had crucified, and then died. So, Judas’s kiss means “with the best of intention or forsake. “Turn the other cheek”（甘受侮辱）from the New Testament, Jesus’advice: Resist not evil, but whosoever shall smite thee on thy right cheek, turns to him the other also. “Build up on the sand”（根基不牢）from the Matthew: “…and doeth them not, shall be likened unto a foolish man, which built his house upon the sand……”in it, “build upon the sand” metaphorical meaning is unstable foundation. There are quite a few English Idioms from religion. Such as: “Benjamin’s mess（最大的份额）, “raise Cain apple of Sodom（金玉其表，败絮其中）,“handwriting on the wall”（不祥之兆）, “God preserve us”（神明保佑）(骆世平，2005. 2.2)etc.C. Idioms from historical allusionBritain as an ancient country passes a long history, which mainly comprises allusion, myths, poem, ancient books and records etc. Among them, allusion is the most important, it reflects the national characteristic. Idioms from history culture are the gems of human cultural heritage. It is worthwhile for us to learn them well. English idioms have their legends and anecdotes about historical figures which have provided rich and variedmaterials, and consequently give a national color to the idioms. It is necessary for us to learn and use the English allusion, it can enlarge our scope of knowledge, widen our field of vision, and it is useful to learn about the idioms’ origin. Maybe we can learn it by its historical events, fables, mythologies and literary works.1. Historical events and folk storiesIn most language, people embellish their speech or writing with references to characters or event from their history, that is to say, idiomatic expressions are closely related to a country’s history. English has a history more than thousand years and has some idioms from historical. For example: “to meet one’s Waterloo”(遭遇滑铁卢)is from the defeat of Napoleon at Waterloo in 1815,which means to be completely defeated. “Dunkirk evacuation”（敦刻尔克撤退）from the world War II and originally meet the retreat of the English-French troops forced by the German now, the expression means to retreat in disorder. “Columbus’s egg”（哥伦布竖鸡蛋）,in the famous story of Columbus’s egg, the explorer, irritated at being told that his exploits were easy, challenged the guests at a banquet to balance an egg on its end, when all had failed, he succeeded by flattening one end by tapping in against the table, a trick that any would than have been able to repeat, its means repetition is easier than innovation.As we all know, Rome and Denmark once occupied Britain for a long time, so the conquest influenced on the Britain to a certain extent: “Six of one and half a dozen of the other”(半斤八两)came from Denmark, whereas “return to one’s muttons”(言归正传)and “do in Rome as the Roman’s do”(入乡随俗)are from France and Rome respectively. Of course, the history of mankind is almost the history of war, which is the source of numerous idioms, as is mirrored in the following: “What millions died that Caesar might be great”(一将功成万骨枯) ,“to put up the sword”(讲和)etc.We can’t sure that if the folk story is true or not, but as a part source of English Idioms, we would rather believe it is a true story, like “eat crow”(被迫认错) “fight like silken cats”(两败俱伤).There is an interest story told that one night, a wife hears a mouse sound in their room, so she asks her husband to drive mouse away, but the man says the door is so cold, he gets cold feel, he will not get up to do anything. In fact, the husband is not because the door cold, but also is afraid the mouse.2. Fable and mythologiesIdioms are usually closely related to distinctive cultural fables and mythologies. As a part of English idioms, though ancient fable stories are short and refined, they teach people many philosophic and educational theories while being narrated. They are also parts of the kindergarden education of children. E.g: “Sour grapes”(酸葡萄)—disparage something that is beyond one’s reach. The allusion is to Aesop’s well-known fable of the fox, which tried in vain to get at some grapes, but when he found they were beyond his reach, he went away saying, “I see they are sour”. “Grin like the Cheshire cat”(咧嘴傻笑),in a children’s story, there is a Cheshire cat kept smiling innocently, so people todescribe someone’s stupid smile as grin like the Cheshire cat. “Alice in wonderland”(幻想的)came from Lewis Carroll’s work Alice’s Adventure in wonderland.As we all know, Greek and Roman civilizations have a great influence on the English language, so the Greek and th e Roman mythologies have greatly enriched the English Idioms. Most English allusion came from the Greek Rome mythology. Le t’s take a glance at following idioms. “Achilles’ heel”(致命弱点)which is from the Greek mythology has the meaning: the one weak spot in a man’s circumstances or character”. “A Pandora’s box”（潘多拉魔盒）（骆世平，2005. 2.4.1）which means the origin of all evils, is also from Greek mythology. Another example, Hercules was one of the most famous heroes in Greek mythologies. He killed two snakes when he was a baby, and was known as a man of muscle. Because of this, he “walks” into the English idioms: “Hercules choice”(永存，不朽), “the Hercules efforts”(费九牛二虎之力), “the pillars of Hercules”(天涯海角). Aesop’s Fable have a greatly influence in English idioms, e.g: “Aladdin’s lamp”(能产生神奇效果的东西)came from Aladdin and the wonderful lamp in Thousand and one Nights. In the story, Aladdin gained a magic lamp and a ring that he was able to call all deities to do anything that he wanted. Another examples, “an open sesame”(芝麻开门)from AliBaba and Forty Thieves.3. .Literary worksMany popular western literary masterpieces have the classic words, phrases and sentences that attract people greatly. They are shaped to evolve the hidden meanings; they are also one of the main sources of English idioms. In English literature, Shakespeare plays a very important role, his dramas are the major source of this kind: “Applaud one to the echo”(掌声雷动)（卢思源，2006.）,“die in harness”(因公殉职),“make assurance doubly sure”(加倍小心),“at one fell swoop”(一举,一下子),“have an old head on young shoulders”(年轻却有头脑),“to claim one’s pound of flesh”(割某人的一磅肉),“out of joint”(杂乱无章),“a horse of different color”(截然不同的事或人),etc. Besides the works of other famous writers also store a great many idioms: “a nine-day wonder”(昙花一现)appears in Troilus and Cressida written by Geoffrey Chaucer; “mind one’s eye”(当心你的眼睛)from Charles Dickens’s Barnaby Ridge; “the ugly duckling”(丑小鸭)is from Han Anderson’s tables; “Friday”(星期五)means faithful, is from Robinson Crusoe written by Daniel Defoe. Many English idioms were came from literary works with which we all familiarity.D. Idioms from traditions and customsCulture is long acquired from customs and habits. These customs and habits are representative of the way of living of a certain speech community and they are mirrored in the habitual speaking of the language. Food is one of the aspects of cultural tradition that are reflected in English idioms. In most European countries, bread, butter, jam, cheese, etc, are usual kind of food in daily meals. On the other hand, animals, sporting and daily life are also made so many idioms. So in English ,there are some idioms like: “bread and butter”(日常所需)（骆世平，2005. 2.6.3）,“hard cheese”(倒霉), “to butter both sides of one’s bread”(过舒适的生活), “clever dog” means a clever boy or guy. “To help a lame dog over a stile”(雪中送炭) ,“love me, love my dog”(爱屋及乌),“dogdays”(伏天),“as strong as an ox”(很健壮) ,“birds of a feather”(性格不同的人)，“in the money”(获奖),“off and running”(进展顺利),“chuck in one’s cards”(认输),“throw in the towel”(投降), “jump the gun”(抢先),“toe the line”(服从命令),etc. Others ,we can learn some new idioms from Walt Disney, for example, “Mickey Mouse”(米老鼠): Small, insignificant.III. ComparisonUsing language in such communication, we often come across some idioms with distinctive cultural characteristics. So it is a very importance and complicated thing for us to understand these idioms correctly. So, we should have a comparison between English and Chinese idioms through their differences and similarity.A. Differences between English and Chinese idioms1. Geographical difference.Geographical environment plays an important role in shaping one country’s culture and human beings have no choices and opacities to change the geography. As a result, idioms based on geographical features appear differences between different countries.Britain is an island country, which does not share land border with any other country except the Republic of Ireland. So, Britain people have a special passion for water. However, the most part of China belongs to inland place where people cannot live without earth. This made difference idioms in the two languages. For example, there is a Chinese idiom showing somebody being extravagant, “挥金如土”,but in English idiom is “spend money like water”；“Don’t cross the bridge till you come to it”(车到山前必有路), “between the devil and the deep sea”(进退维谷), “all is fish that comes to one’s net”(抓到篮里便是菜).2 . Conventional differencesOne nation’s custom is formed through a long history and firmly rooted in people’s mind. It is closely related to national psychology and acts as an important source of idioms. In different countries and nations customs drastically differ in various aspects. Due to that, a lot of idioms turn out with varied dress.Take food habit for example, cake has been a common food in English for a long history. On the other hand, dishes are common in China, so ,in English idiom “a piece of cake” is tell the same meaning like(小菜一碟)in Chinese. Other examples are related to the habitual way of working in the field. E.g.: Chinese say “力大如牛”while English say “as strong as a horse”.3.. Religious differencesNumerous idioms were generated from the function of religion. Religion which exists in every country and nation affects much in people’s belief and life, especially before the modern civilization. The people in different countries mostly believe in different schools of religion. Therefore some differences of idioms between Chinese and English can betraced back to the origin of religion. Religion played a key role in English society, especially before capitalization, innumerable idioms are originated from the Bible, such as “to put new wine in old bottles”(旧瓶装新酒)(庄和诚，2002，p447),“my God”(上帝), “to make one’s hair stand on end”(使人毛骨悚然), besides, the idiom “as poor as a church mouse”（一贫如洗）is also somewhat influenced by religion. Be different from Britain culture, Chinese culture evolved from Confucian School, Taoist School. There are traces of Taoist principles and Confucian principles in Buddhist doctrines. A large number of Chinese idioms can be traced back to Buddhist School. Such as “道高一尺，魔高一丈”(where God has his church, the devil will have his chapel), “临时抱佛脚”(seek help at the last moment), ”佛法无边”(the powers of Buddha are unlimited) （顾曰国，1997.9 p.285），”一尘不染”（as clean as Whistle）（徐栋良，高红，2004 p.6）.B.Similarities between English and Chinese idiomsAlthough there are many differences between English and Chinese idioms origin, they also have some similarities. Sometimes, we can borrow them each other so that our communication would be changed frequently and easily. For example, as we all know, LiangShanBo and ZhuYinTai were lovers, but as foreigners, they don’t understand its meanings, maybe they don’t know about the story. How would we explain for them? In such condition, if we have borrowed their culture to introduce it, we can tell them like this: they are Romeo and Juliet in China. I believe that they can understand the love story without any difficulty. Others, “the emperor of Qin- Dynasty” j ust like “Caesar” in westerner. “Damon of Pythias”, which some men urge to translate it directly, while other men believe that translating it into men believe friendship unto death（莫逆之交）or friends who are willing to die for one another is better（刎颈之交）. Because the majority of Chinese do not know Damon and Pythias, we can explain them into GuanZhong and BaoShuYa in Chinese may enable the Chinese easily to understand. “There are the Greek gifts for you”(希腊人的礼物) just like the similar Chinese idiom “the yellow weasel goes to his respects to the hen—with the best of intention (黄鼠狼给鸡拜年—不安好心),“Burn one’s boat” just like(破釜沉舟)in Chinese.。

Idioms provide a rich tapestry of linguistic tools that can add nuance, emphasis, and creativity to a student's writing and speech. Instead of relying on more straightforward, literal language, students who are adept at using idioms can convey their ideas with greater expressiveness and impact, captivating their audience and leaving a lasting impression.In the context of high school English, the study of idioms can also enhance a student's understanding of the cultural and historical contexts that shape the language.

One approach is to introduce idioms in the context of reading and writing exercises, where students can practice identifying, interpreting, and using these expressions in their own work. Teachers can also incorporate idioms into vocabulary lessons, helping students to understand the origins and meanings of these unique linguistic constructs.Another effective strategy is to encourage students to actively seek out and learn new idioms, either through independent research or through collaborative activities.

高中英语之巧记颜色俚语color idioms(课件)

（3）yellow 黄色
黄色是太阳公公的本色，它饱含智慧与生命力，让人显得年轻有朝气，它被认为是知识和光明的象征。黄色在英语和汉语中的引申含义差别比较大。在英语中，yellow可以表示“胆小、卑怯、卑鄙”的意思，例如： a yellow dog 可鄙的人He is too yellow to stand up and fight. 他太软弱，不敢起来斗争。汉语中黄色一词有时象征低级趣味、色情庸俗的意思，如黄色电影、黄色书刊等。这些名称中的“黄”与英语中的“yellow”无关。能够表示汉语中这些意思的词汇应该是：pornographic、vulgar等。然而，英语中另一个颜色词blue却常用来表示汉语中这类意思，如blue jokes（下流的玩笑）， blue films（黄色电影）等。
Yellow is often associated with happiness, optimism, and cowardice. Here are some common yellow idioms:Yellow-belly: coward胆小鬼Example: He was a yellow-bellied cowboy. He always ran away from a fight.Belly means stomach. If your belly is yellow, you are not brave. This idiom isn’t used as much nowadays as it was in the past.
卑鄙无耻的小人
brown(棕色）
brown sugar
红糖
brown nose
献殷勤，拍马屁
颜色的具体含义
红色是一种热烈的颜色，它象征着鲜血、烈火、生命和爱情。红色的热情让人有一种勇敢的冲劲，它能鼓舞人的情绪。在我国，红色是火，是吉庆、热情的象征，但在英语国家的人眼中红色则意味着流血、危险或暴力。同时在英语和汉语中，红色有时可以完全对应，有时却大相径庭。红旗 red flag 红糖 brown sugar 红茶 black tea 红榜 honour roll 红豆 love pea 红运 good luck

英文作文idiom

英文作文idiom英文，Idioms are an essential part of language and are often used in everyday conversations. They add color and depth to our communication, making it more interesting and expressive. Idioms are a group of words established by usage as having a meaning not deducible from those of the individual words. They are often culturally specific and can be quite confusing for non-native speakers.For example, the idiom "kick the bucket" means to die. If someone says, "I hope I don't kick the bucket before I turn 50," they are expressing a fear of dying before reaching a certain age. This idiom is not meant to be taken literally, and understanding its figurative meaning requires some cultural and linguistic knowledge.Another common idiom is "hit the nail on the head," which means to describe exactly what is causing a situation or problem. For instance, if someone says, "You hit thenail on the head with that analysis," they arecomplimenting the accuracy of someone's assessment. Again, this idiom doesn't make sense when taken literally, but it adds a vividness to the language.中文，习语是语言中不可或缺的一部分，通常在日常对话中使用。

"Bite the bullet":This idiom has its roots in battlefield medicine when soldiers would bite on a bullet during surgery to endure the pain without anesthesia. Figuratively, it means facing a difficult situation or unpleasant task with courage and resilience. For instance, "I knew I had to bite the bullet and confront my fear of public speaking."3. "Piece of cake":This idiom suggests that something is very easy to do. Its origins are unclear, but it's commonly believed to have originated in the United States in the 19th century. An example sentence would be, "Don't worry, passing the exam will be a piece of cake for you."4. "Cost an arm and a leg":This colorful idiom refers to something being extremely expensive.

An example sentence would be, "She hit the nail on the head when she identified the main issue in our project."6. "Jump on the bandwagon":This idiom refers to joining a popular trend or activity. It originates from political campaigns where politicians would ride a bandwagon to gain attention and followers. For example, "After seeing all my friends doing yoga, I decided to jump on the bandwagon and give it a try."7. "Spill the beans":To "spill the beans" means to disclose a secret orreveal information prematurely. Its origins are uncertain, but it may stem from an ancient Greek voting system where beans were used as ballots.

They add color, depth, and cultural context to conversations and texts, making them an essential part of Chinese communication. In this document, we will explore the origins, meanings, and usage of idioms in the Chinese language.Origins of Chinese IdiomsChinese idioms can be traced back to ancient times, with some idioms dating back thousands of years.

The origins of these idioms are often associated with historical events, folk tales, or philosophical concepts.The Structure of Chinese IdiomsChinese idioms typically consist of four characters, known as chengyu.

崭露头角英语短语

崭露头角英语短语English Idioms":Stepping into the Limelight: English IdiomsThe English language is a rich tapestry of words and expressions that have evolved over centuries to capture the nuances of human experience. Among the most captivating and versatile linguistic elements are idioms - those quirky, often metaphorical phrases that add color, depth, and personality to our communication. Idioms are the linguistic gems that allow us to step into the limelight of expressive language and convey our thoughts and emotions in a way that is both vivid and memorable.One of the most remarkable aspects of English idioms is their ability to transcend the literal meaning of the individual words that comprise them. Take, for example, the idiom "to let the cat out of the bag." On the surface, this phrase seems to be about a rather mundane act of revealing a secret. However, the true meaning of the idiom goes beyond the simple act of disclosure - it suggests an element of surprise or betrayal, as if the secret had been carefully guarded and its revelation was unexpected or undesirable.This transformative quality of idioms is what makes them so captivating and valuable in the realm of language. They allow us to move beyond the constraints of literal interpretation and tap into the rich tapestry of cultural references, metaphorical associations, and emotional nuances that give language its depth and versatility. By incorporating idioms into our speech and writing, we can elevate our communication, adding layers of meaning and expressiveness that would be difficult to achieve through the use of literal language alone.Moreover, the diversity and creativity of English idioms is truly astounding. From the whimsical "to let the cat out of the bag" to the more serious "to bite the bullet," the English language is brimming with idioms that draw upon a vast array of cultural references, historical events, and everyday experiences. These expressions not only add color and personality to our language but also provide a window into the collective consciousness of the English-speaking world.Take, for instance, the idiom "to hit the ground running." This phrase evokes the image of someone who is ready to take immediate action, to dive headfirst into a new endeavor with energy and determination. The metaphor of "hitting the ground running" suggests a sense of urgency, efficiency, and a refusal to waste time. By using this idiom,we can convey a wealth of information about a person's mindset and approach to a particular situation, all in a succinct and impactful way.Similarly, the idiom "to be on the same page" speaks to the importance of shared understanding and alignment in communication. The metaphor of being "on the same page" conjures up the image of people reading from the same script, working towards a common goal with a shared perspective. This idiom is particularly useful in professional and collaborative settings, where the ability to effectively communicate and coordinate is essential for success.The richness and versatility of English idioms is not limited to their metaphorical power, but also extends to their ability to capture the nuances of human emotion and experience. Consider the idiom "to have a chip on one's shoulder." This phrase suggests a sense of resentment, a lingering grievance that a person carries with them, often as a result of perceived injustice or mistreatment. By using this idiom, we can convey a wealth of information about a person's emotional state and their approach to interpersonal interactions, all in a concise and evocative manner.Likewise, the idiom "to be over the moon" speaks to the profound joy and elation that a person may feel in a particular situation. The metaphor of being "over the moon" conjures up images of soaringhigh, of experiencing a level of happiness and excitement that transcends the bounds of ordinary experience. This idiom allows us to express the depth and intensity of human emotion in a way that simple descriptive language often fails to capture.The power of English idioms lies not only in their ability to add color and personality to our language, but also in their capacity to bridge cultural divides and facilitate cross-cultural communication. Many idioms are deeply rooted in the cultural traditions and historical experiences of the English-speaking world, and by learning and using these expressions, individuals from diverse backgrounds can gain a deeper understanding of the nuances and subtleties of the language.Take, for example, the idiom "to let the cat out of the bag." This phrase is believed to have originated in the 18th century, when unscrupulous vendors would sometimes try to pass off a cat as a piglet by hiding it in a bag and selling it as a genuine piglet. The revelation of this deception was considered a betrayal of trust, and the expression "to let the cat out of the bag" came to symbolize the act of revealing a secret or exposing a deception.By understanding the cultural and historical context behind this idiom, individuals from different backgrounds can gain a deeper appreciation for the richness and complexity of the English language. Moreover, the use of such idioms in cross-cultural communicationcan help to build bridges and foster mutual understanding, as shared linguistic experiences can serve as a common ground for people from diverse cultural and linguistic backgrounds.In conclusion, the world of English idioms is a vast and captivating realm that offers endless opportunities for linguistic exploration and personal expression. From the whimsical to the profound, these linguistic gems have the power to transform our communication, adding depth, nuance, and personality to the way we express ourselves. By embracing the richness and versatility of English idioms, we can step into the limelight of expressive language and unlock new avenues for creative and effective communication.。

Clothing IdiomsFood IdiomsGeography and Weather IdiomsSports IdiomsSports idioms generally originate from a specific sport such as baseball or sailing. Over time these phrases have come to mean something that can be used in everyday life. While most sports idioms can still be used when discussing sports, they are even more common in other areas of life, especially the business world. You can study these idioms just as you would any other vocabulary. Look at the model sentences and practise writing your own. When you think you have mastered all of the idioms, take thequiz and test your knowledge. More importantly, try using them at work, school, and social events. You will sound like a pro!Body IdiomsAnimal IdiomsEnglish IdiomsIdioms are fun and useful expressions that usually cannot be understood by defining the separate words.For example, if your host mother says, "I think it's time to hit the hay", she means, "I think it's bed-time"! You would not be able to understand her by looking up the words hit and hay. Like phrasal verbs, these expressions need to be memorized as a whole. Try visualizing them or drawing pictures when you study them. For example, draw a picture of a cow sleeping in some hay. The idiom out of the blue means "unexpectedly". Your teacher or homestay family will call you one smart cookie if you come up with an idiomatic expression like that when they least expect it!Most idioms don't seem to make any sense because their origins are so old. Some of them come from ancient literature or even classic films. Learning the background of idioms can help you to remember them.Try checking your dictionary or asking a teacher or native speaker if they know the origin. Remember, not all idioms are considered Standard English. Some English-speaking regions use specific idioms that other native English speakers have never heard before. You can find information about most expressions by looking them up online.Try studying these idioms by learning one list at a time. Or, use these lists to help you when you come across an idiom you don't understand. One important thing to remember is that the subject of the idiom doesn't usually relate to the meaning.。
