每日英语听力 Day 21

so let me talk a little bit about that. so during the christmas season, what happens? well, first of all let me talk about when this season is. so i think that technically the christmas season starts at right after thanksgiving, for some people the christmas season starts even earlier they are->\ already get in the christmas spirit earlier on in the year.

however i think that for most people after thanksgiving it is christmas time it is the christmas season so this starts at the end of Novernber->November of course and then it continues on through December so we have multiple weeks we have a full month of->where everything feels like christmas the season is in full swing in English when we say that something is in full swing we are saying that you are now in this period you are in this season it is happening now completely so by the time December comes the christmas season is in full swing and you start to see this christmas culture all around you.

so there is the visual aspect of this christmas season so of course the decorations are a big part of this and christmas decorations usually come up after thanksgiving and there->they are taken down in January usually at the beginning of January that is usually when you see these decorations however sometimes you will see them even earlier than that and you will see them stay up even later than the beginning of January but usually most people have their decorations up throughout the month of December thoughout that whole month.

and we have some special areas throughtout our cities where we have really really cool christmas decorations and christmas lights so if you visit the us during the month December and you are in a big city there will probably be multiple neiborghoods where the whole neighborhood has really incredible christmas decorations and each neighborhood that does this has a different nickname a name for itself so the name may be candycandylate->Candy Cane Lane or star light circle or something like that.

and people will go from different parts of the city to see this neighborhood and see all of the decorations and the lights there this is a really cool tradition and->that we have in the us during the month of December i make decide->i am excited to take my family to see some of these neighborhoods this season and they sometimes sell things in these neighborhoods at night when a lot of people are walking through the neighborhood they might sell hot chocalate or cookies or other snacks it is a whole experience when you do this so that is a really cool things->\ and there is also the audio aspects of the christmas season.

i will talk->talked about the visual aspect but there is also the audio aspect because there is christmas music everywhere everywhere you turn you hear christmas music by the way when we say everywhere you turn we just mean everywhere you go everywhere you look everywhere around you so everywhere you turn there is christmas music play->playing when you walk into a store if they have music at that store changes are->chances are is->it is christmas music and we have a whole genre of music here called christmas music.

musical artists release christmas albums specifically for this season so there is a whole genre dedicated to christmas music so that is something that you will hear everywhere. everywhere you go you hear christmas music so it sounds like christmas during this month and people watch christmas movies this is a genre of movies here in the us we have christmas movies there are tons of tons of christmas movies and some families have the tradition of watching the same christmas movie or the same christmas movies every year.

and they have already seen those movies 20 times but they continue to watch them every year because it is the tradition during the christmas season my sisiter does this i think she watches a lot of christmas movies and rewatch them every year i do not really do this but when i was a kid there are a couple christmas movies that i really liked and i watched them year after year so i participated in that a litle bit when i was younger.

and there are chritmas cards that you see in people’s houses a christmas card is a card that you make by taken->taking a picture often times->oftentimes with a prfessional photographer not always but sometimes you take a picture during this season with you and your family and you create these christmas cards and you send these christmas cards to your friends and your family members and some people write something on these christmas cards some people write things about what each person in their family has done this year.

they give you an update on the life of different family members some people do that with these cards but other people just put the names of each people on the card or maybe they just put the last name of the family but the picture is the most important part and people will put these christmas cards on their refrigerator they will use a magnet to stick these cards from different people on their refrigerator or somewhere else in their->the house sometimes and so you can see the pictures of all the->their different friends and family members there on the fridge.

内容概要:本文介绍了一种基于蒙特卡洛模拟和拉格朗日优化方法的电动汽车充电站有序充电调度策略,重点针对分时电价机制下的分散式优化问题。通过Matlab代码实现,构建了考虑用户充电需求、电网负荷平衡及电价波动的数学模【电动汽车充电站有序充电调度的分散式优化】基于蒙特卡诺和拉格朗日的电动汽车优化调度(分时电价调度)(Matlab代码实现)型,采用拉格朗日乘子法处理约束条件,结合蒙特卡洛方法模拟大量电动汽车的随机充电行为,实现对充电功率和时间的优化分配,旨在降低用户充电成本、平抑电网峰谷差并提升充电站运营效率。该方法体现了智能优化算法在电力系统调度中的实际应用价值。; 适合人群:具备一定电力系统基础知识和Matlab编程能力的研究生、科研人员及从事新能源汽车、智能电网相关领域的工程技术人员。; 使用场景及目标:①研究电动汽车有序充电调度策略的设计与仿真;②学习蒙特卡洛模拟与拉格朗日优化在能源系统中的联合应用;③掌握基于分时电价的需求响应优化建模方法;④为微电网、充电站运营管理提供技术支持和决策参考。; 阅读建议:建议读者结合Matlab代码深入理解算法实现细节,重点关注目标函数构建、约束条件处理及优化求解过程,可尝试调整参数设置以观察不同场景下的调度效果,进一步拓展至多目标优化或多类型负荷协调调度的研究。
<think>我们正在处理用户的问题:"完成英语"。用户意图是“完成英语”,这可能意味着用户想要了解如何完成英语学习、如何提高英语水平等。由于问题比较简短,我们需要根据常见的英语学习需求来推测用户可能的意图。 常见的与"完成英语"相关的需求可能包括: 1. 完成英语作业或练习 2. 提高英语水平以达到某个目标(如通过考试、流利交流等) 3. 英语学习的方法和技巧 4. 如何快速完成英语学习任务 考虑到这些可能性,我们将进行网络搜索,重点放在如何高效完成英语学习任务、提高英语水平的方法等方面。 搜索关键词:如何快速完成英语学习、高效英语学习方法、完成英语作业的技巧 注意:由于我们无法实际调用搜索引擎,这里将模拟搜索结果,基于已知的英语学习知识构建答案。 根据网络搜索的结果,以下是一些高效完成英语学习的方法: 1. 制定明确的学习计划:设定具体的学习目标和时间表,将大任务分解为小任务。 2. 利用碎片时间学习:使用移动应用(如Duolingo、百词斩)在零碎时间进行单词记忆或听力练习。 3. 沉浸式学习:通过观看英语影视剧、听英语歌曲、阅读英语新闻等,创造语言环境。 4. 练习输出:通过写作和口语练习来巩固所学,可以使用语言交换平台(如HelloTalk)与母语者交流。 5. 使用高效学习工具:如Anki(基于间隔重复的闪卡系统)来记忆单词和短语。 此外,对于完成英语作业,可以: - 先理解作业要求,明确需要完成的任务类型(如阅读理解、写作、翻译等)。 - 合理分配时间,避免拖延。 - 利用在线资源(如Grammarly检查语法,DeepL辅助翻译)提高效率,但要注意避免直接抄袭。 我们将按照要求组织答案,避免使用步骤词汇,采用多个方法或步骤,每个步骤间换行。 同时,注意在最后添加相关问题部分。 由于问题中没有涉及代码和公式,我们不需要使用代码块和数学公式格式。 下面开始构建答案:</think>### 高效完成英语学习的实用方法 **沉浸式学习法** 创建英语环境:将手机/电脑系统语言改为英语,每天听30分钟英语播客(推荐BBC Global News Podcast)。使用英语学习APP(如Duolingo、Memrise)进行每日15分钟词汇训练,配合Anki记忆卡巩固生词 **结构化训练方案** 采用4:3:2:1时间分配: - 40%听力训练(TED演讲/影视剧片段) - 30%阅读训练(The Guardian简讯/Graded Reader分级读物) - 20%口语练习(Cambly/iTalki外教对话) - 10%写作训练(LangCorrect批改平台) **高效工具组合** ```python # 自动化学习提醒脚本示例 import schedule import time def vocabulary_drill(): print("执行每日词汇训练") def listening_practice(): print("开始听力练习") # 设置每日学习计划 schedule.every().day.at("09:00").do(vocabulary_drill) schedule.every().day.at("19:30").do(listening_practice) while True: schedule.run_pending() time.sleep(60) ``` **考试冲刺策略** 针对标准化考试(雅思/托福): - 每周完成2套真题模考,使用$S = \frac{C}{T} \times 100$ 计算得分率($C$为正确题数,$T$为总题数) - 建立错题本记录高频错误类型 - 参加线上模考社区(如IELTS Online Tests) **持续进步机制** 设置SMART目标: - 具体(Specific):"每日掌握10个学术词汇" - 可衡量(Measurable):每周词汇测试正确率$A \geq 85\%$ - 可实现(Achievable):从CEFR B1到B2级过渡 - 相关性(Relevant):满足留学/职场需求 - 时限(Time-bound):3个月达成目标
