代词it的翻译

代词it的翻译

代词it的翻译作者:李颖来源:《新一代》2014年第08期摘要:英语代词在语篇中使用频率远远高于汉语代词,有人称代词、非人称代词、关系代词等等。

有时一句话中出现几个代词,这就给学生带来极大的困扰。

代词“It"一词的使用频率也相当高,很容易造成学生对其理解不准确。

因此,本文将从It作为指称代词和非指称代词的用法入手,分析It在各个语境中的不同翻译。

同时,本文将对It的翻译规律进行归纳和总结,使学生可以更准确无误地翻译It。

关键词:翻译;指代;非指代一、It的特点It是第三人称,单数,中性的人称代词。

其用法却变化多端,通常有指代和非指代用法之分,而且其使用频率也相当高。

一般说来,它不会给翻译带来很棘手的问题。

但这仅仅是一般情况而言,换言之,在某些情况下,要将It的语义悟透,要找一个恰当的对应词来表达它的意义,绝非易事。

它就是语篇中一个不可或缺的螺丝钉,是语篇体系中的一个卒子。

二、It的翻译(一)作为指称代词的翻译1.It可以用来指动物,甚至可以指不知其性别的或性别无关紧要的婴幼儿。

如:What’s the matter with that child? It looks ill. 那个小孩怎么了?他看起来好像病了。

2.除此以外,It可以指代前面的内容,也可以指代后面的内容,指代前面的内容时,它的先行词可以是一个词组,也可以是一个分句,一个句子或几个句子所表达的全部或部分内容;It指代后面的内容时,常常指分句或句子所表达的内容。

3.在附加疑问句中,it可被用来代替all或everything。

All is going well,isn’t it?一切顺利,不是吗?(二)作为非指称代词时的翻译1.虚义It(1)虚义It用在表示时间、日期、天气、温度、距离等意义的句子中,It作形式主语,它虽然处于主语的位置上并没有实际意义,因此称为“虚义it”(empty it)。

①It is very warm today. 今天天气很热。

it可以指代句子的用法

it可以指代句子的用法IT 可以指代句子的用法引言:在日常英语交流中,我们经常使用缩写词和缩写句子来简化表达。

其中一个常见的缩写是"IT",它有多种含义,包括信息技术、信息科学、管理类、工程类等。

然而,在某些情况下,"IT" 也被用作一个独立的词语来指代某个事物或概念。

本文将探讨 "IT" 如何用于句子中,并分析其不同应用方式。

一、 "IT" 作为主语或宾语1.1 提供背景信息当我们想要提到某个事物时,但并不知道具体名称或只关注于该事物的特定方面时,我们可以使用 "it" 作为主语。

例如:- It's raining outside.(外面在下雨。

)- It's getting dark.(天黑了。

)- It's cold today.(今天很冷。

)这些句子中的 "it" 并非具体指代某个物体,而是表示天气、时间或环境等抽象概念。

1.2 替代先行词当一个名词的前后出现多个修饰成分时,为了避免重复使用该名词,我们可以使用 "it" 作为前面修饰成分的替代。

例如:- My car is blue, but I don't like it.(我的车是蓝色的,但我不喜欢它。

)- I bought a new book yesterday and I've already finished it.(昨天我买了一本新书,现在已经读完了。

)这些句子中的 "it" 替代了前面的名词 "car" 和 "book",避免了重复。

二、 "IT" 作为占位符或形式主语2.1 占位符有时候,在英语句子中,我们需要一个主语来使句子完整,但实际上并没有具体的事物或概念需要指代。

英语中强调句的先行词用主格

英语中强调句的先行词用主格

在英语中,强调句的先行词一般使用主格。

强调句的结构通常是“it is/was + 先行词+ that/who + 其他”。

例如:It is I who am responsible for the mistake. (我才是犯了错误的人。

)It was he who made the suggestion. (他才是提出建议的人。

)注意,在强调句中,先行词通常要用主格,即使它在非强调句中是宾格。

例如:She gave the book to me. (她把书给了我。

)It was me that she gave the book to. (她把书给了我。

)在强调句中,先行词通常使用主格,但也可以使用宾格,这时候句子的意思就会有所不同。

例如:It is me that she gave the book to. (她是给我的。

)在这个句子中,先行词使用宾格,表示“我是被给了书”,而不是“她是给我的”。

总的来说,在英语中,强调句的先行词通常使用主格,但也可以使用宾格,这时候句子的意思就会有所不同。

好的,在英语中,强调句用来强调句子中的某个部分,使得这个部分更加突出。

通常情况下,强调句的结构是“it is/was + 先行词+ that/who + 其他”。

例如:It is the teacher who is responsible for the mistake. (老师才是犯了错误的人。

)It was the cat that woke me up. (是猫把我吵醒的。

)在强调句中,先行词通常是被强调的部分,其余的部分是附属的。

例如,在第一个句子中,先行词是“teacher”,表示“老师”是被强调的部分,而“responsible for the mistake”是附属的。

好的,那么我来为你提供一些关于强调句的练习题。

请看下面的句子,选择正确的答案:It was _____ who broke the vase.a. heb. hisc. himIt is _____ who is going to the store.a. Ib. mec. myIt was _____ who told you about the party.a. sheb. herc. hersIt is _____ who is responsible for the mistake.a. web. usc. our答案:1. a 2. a 3. a 4. a希望这些练习题能帮助你更好地掌握强调句的用法。

which和it的用法区别

which和it的用法区别

which和it的用法区别一、which和it的基本用法1. which的用法Which是一个疑问代词,用于在选项中表示选择或区分事物。

它可以引导一个非限制性定语从句(non-restrictive clause),给出附加信息,对前面提到的事物进行进一步描述或解释。

例如:- My car, which is blue, is parked outside.我的车是蓝色的,停在外面。

此句中,“which is blue” 是一个 non-restrictive clause,它提供了关于“我的车”的额外描述,“which” 引导该从句。

此外,Which也可用于引导疑问句,询问选择。

例如:- Which book do you want to read?你想读哪本书?2. it的用法It作为代词时,通常指代先前提到过的某个特定事物或概念。

它可以充当主语、宾语、形式主语或形式宾语等,在句子中起到占位符的作用。

举个例子: - It is raining heavily outside.外面下着大雨。

在这个例句中,“it”指代“雨”,充当主语。

3. which和it的区别a. 用途不同:which通常用于引导附加信息从句或选择性问题;而it则为占位符,用于指代事物或概念。

b. 位置不同:which通常出现在附加信息从句之前;而it则可以出现在句子的任何位置。

二、which和it的具体用法举例1. which引导非限制性定语从句Which可以用来引导非限制性定语从句,对先行词进行进一步解释或补充说明。

以下是几个例子:- My sister has a cat, which is very cute.我姐姐有一只猫,它非常可爱。
