介词
介词的原理Introduction名词和介词在现实世界中看的着摸得见,但是介词不一样,往往抽象难以理解。 牛津词典对10亿单词做出分析后,列出了英语中最常用的单词。其中最常用的30个单词中,10个就是介词。足以说明介词在英语使用中非常重要。 Official Website 据说介词这个术语来自清朝末年的语言学家马建忠老师,原话是: 凡虚字用以连实字相关之义者,曰“介词”。介字云者,犹为实字之介绍耳。 也就是说介词是为了介绍实词而存在的,其中实词代表具体的,有意义的词,甚至是看得见摸得着的东西。与实词相对的就是虚词。 在英文中,介词为:preposition,这个词本身符合英语构词法,pre表示在前的,position是位置。即前置词。介词通常是放置在名词,代词前,给他们增加附加信息的词。 介词的附加信息:时间信息,空间信息,方式信息,逻辑信息(原因, 目的,对象) 时间信息: 我在8点前吃饭。- before 我在8点时吃饭。- at 我在8点后吃饭。- after 空间信息 我在屋子里吃饭。- in 我在屋子外吃饭。- out 猫在桌子上吃饭。-...
语气
谓语动词的三大本领时间 状态 语气 语气陈述语气(Indicative Mood)描述现实:I ate the apple. 疑问语气 与陈述语气对应 Did I eat the apple? 祈使语气(Imperative Mood)命令、请求 Eat that apple. 实际上是第二人称的陈述语气的省略版 -> You eat that apple. Give me a five. -> You give me five. 虚拟语气(Subjunctive Mood)1. 表示对”不可能”的假设与现在事实相反 Chinglish: If I am a bird, I will fly to somewhere I enjoy. English: If I were a bird, I would fly to somewhere I enjoy.(这里不论人称全都用were) 与将来事实相反(将来要发生的事件可能性极小) NOTE: 这行不是虚拟语气:If I (shall) get 80 in English test next time, I...
谓语动词
又被称为“限定性动词”(finite verbs),该动词被主语所有,所以是限定性动词 谓语动词是句子的核心,而非谓语动词只能出现在句子的非核心部分 及物动词不及物动词系动词谓语动词人称变位I am, I eat She is, She eats They/You are, They/You eat 谓语动词时态变位I eat, She eats, They eat I ate, She ate, They ate
非谓语动词
特点除了不可以做谓语,其他句子成分均可 丧失动词的三大特性,但仍然是一种动词,同时具有了一部分名词的性质 非谓语动词的分类动词不定式不定时是指:不受人称和时态限制 做主语To eat an apple a day is good for your health. It is good for you to eat an apple a day. Eating an apple a day is good for you. 做宾语I like to eat apples. I consider apples sweet. I stop to sleep. 宾语补足语I hope you can get a good score in next examination. 注意区分宾语和宾语补足语,宾语承接谓语动词发起的动作,而宾语又承接宾语补足语的动作结果或状态。 I find it easy to learn English. 定语I have a lot of apple to eat.(区分定语还是宾语补足语,只需要看后面这个东西是否能) 状语I was happy to...

What is Bandwidth
云服务器带宽和流量的区别云服务器的带宽配置主要分为两种描述方式:带宽上限 和 流量上限。以下是它们的详细介绍和对比。 1. 带宽上限(如 4Mbps)含义带宽表示服务器与网络连接的速率上限,单位通常为 Mbps 或 Gbps。 示例:4Mbps 表示每秒最多传输 4 兆位数据,实际速率约为 0.5 MB/s。 适用场景限制峰值流量:控制服务器的峰值速率,适合需要稳定网络连接的场景。 持续传输数据:如 HTTP 服务、流媒体等需要长时间稳定传输的应用。 常见原因固定速率分配:云厂商为入门级套餐设定的固定带宽。 按峰值带宽收费:更便于用户管理成本。 计算预估流量假设每天持续使用 4Mbps 带宽,可计算月流量: 1月流量 = 4 Mbps × 3600 秒/小时 × 24 小时/天 × 30 天 ÷ 8 结果约为 1.3TB/月。 2. 流量上限(如 2TB)含义流量上限是指每月可传输的数据总量(上传+下载),但不限制速率。 适用场景弹性使用:突发性流量需求高,例如大文件下载、CDN...
