语法知识讲解

【高清课堂:被动语态的概念 】

被动语态的概念

1.

英语中有两种语态:主动语态和被动语态。 2. 主动语态表示主语是动作的执行者

例如: Many people speak Chin ese.

3. 被动语态表示主语是动作的承受者

例如:上句可变为

Chin ese is spoke n by many people.

为什么要用被动语态?

1?当关注的是事情本身而不是动作的执行者,或者根本不知道动作的执行者时。如 The meet ing was put off.

My car has bee n moved.

2. 动作的执行者很明确时或强调承受者时。

The cere mony was reported in the n ews last ni ght.

If you break the school rules, you will be puni shed.

3. 当动作的执行者是"people ”或 “one ”时。 He is believed to have inven ted the computer.

Advertiseme nts are see n everywhere.

4. 修辞的需要,为了使句子更加简练、匀称

现在进行时态的被动语态的构成:

be + being + done My new house is being decorated.

我的新房子正在装修。

Money is being collected for the Hope Project.

现在进行时态的被动语态

现在进行时态的被动语态的形式:

(1)肯定式:主语+ be + bei ng +及物动词的过去分词+其他。

Ano ther bridge is being built over the Cha ngjia ng River.

长江上正在修建另一座大桥。

⑵否定式:主语+ be + n ot + being +及物动词的过去分词+其他。

The engin eer is not being treated fairly.

目前这位工程师没有受到公平的待遇。

(3)—般疑问式:Be+主语+ bei ng +及物动词的过去分词+其他?

Is the life of pan das being studied by the scie ntists?

科学家们正在研究熊猫的生活习惯吗?

(4)特殊疑问式:特殊疑问词+ be +主语+ bei ng +及物动词的过去分词+其他?

Where is the new scie nee lab being built?

新的科技馆正在哪里建造?

现在进行时态的被动语态的用法:

(1)表示此时此刻正在进行的被动的动作。

My sister is now being in terviewed.

我妹妹正在面试。

Yao Mi ng is now being treated in China.

姚明正在中国接受治疗。

(2)表示现阶段正在进行的被动的动作。

I feel very surprised that the win dow of our classroom is freque ntly being broke n.

我感到很吃惊的是我们教室的那扇窗户经常被打破。

用现在进行时表将来

英语中大家对be going to和will(shall)+动词的形式都表示将来意义这个知识点并不陌生。 比如: I’m going to Japan next week. =I will go to Japan next week.我下周将要去日本。 be going to是现在进行时的结构,但是时态表示将来。今天我将要继续分享“am/is/are+ doing”是现在进行时的结构,通常表示“现在”这个时间里“正在”发生的动作。但是表示暂时性动作的动词,通常情况下,可以用现在进行时表示将来。英语中表示暂时性动作,常用进行时表示将来的动词有come,go,arrive,leave,start,fly,die等。 比如: Don’t worry. The train is arriving here soon. 别着急,火车马上就到了。 We’re leaving Beijing for home. 我们就要离开北京回家了。 这种用法所用的动词多是位移动词。所谓位移动词顾名思义就是位置上会发生改变,比如come,go,leave。:进行时表将来的动词需要特殊记忆(开始离开来去到达,start,begin,leave,come,go,arrive) 并且这类词不止能用现在进行时表示将来。 比如: He’s leaving for Shanghai. He’ll leave for Shanghai. 同时现在进行时也可用于某种非位移动词。 比如: I’m meeting you after school. 放学后我见你。

What are you doing next Sunday?下星期天你要干什么? 初中阶段用现在进行时表将来的位移动词和非位移动词汇总如下,同学们可特殊记忆。 接下来我们看一道现在进行时表将来的易错题: The engineer is returning from Hong Kong _____ a few days. A. since B. for C. in D. after 很多同学一看选D,正确答案C。 解析:is returning是现在进行时表示将来。 since是指从...起,一般与现在完成时配合,而且后面跟的是时间点。如since last sunday从上周六起;

现在进行时态语法

现在进行时态语法 现在进行时态的构成: 现在进行时态由“be(is、am、are)+ 动词的-ing”构成。其中,be是助动词,也就是和后面的动词(-ing形式)一起构成现在进行时,它本身没有意义。现在进行时它表示的是此刻正在进行或发生的动作。 现在进行时态的用法1.: 现在进行时态由“be(i s、am、are)+ 动词的-ing”构成。其中,be是助动词,也就是和后面的动词(-ing形式)一起构成现在进行时,它本身没有意义。现在进行时它表示的是此刻正在进行或发生的动作。由此我们应注意三点:一是时间为现在,甚至为此刻,而不是过去或将来;二是动作在进行,而不是已经发生了,或还没有发生;三表示一个动作,而不是状态。 例如:“他现在想打篮球”,虽然该句子表示的是现在,但这里“想要”表示状态,因此没有现在进行时。只能翻译为:He wants to play basketball now. II.动词的在分词的构成 大部分动词的现在分词都是直接加上-ing,如:visit→visiting;work → working;turn → turning等。但下列几种形式也需要同学们记清楚: 1. 动词以不发音的字母e结尾,一般去掉e,再加-ing,例如: write→writing;leave→leaving;save → saving;pollute → polluting 当然我们需要注意两小点:1)die、lie、tie的-ing形式分别是dying、lying、tying。2)be、agree等动词的-ing形式直接加上-ing,因为这里的e、ee都发音。 2. 以重读闭音节结尾的动词末尾只有一个辅音字母(x例外),要重写该辅音字母,再加-ing。例:run→running;begin→beginning;swim→swimming;stop → stopping。 注意:fix → fixing

Are you staying here till next week? 现在进行时除表示现在外,还可表示将来,常有\"意图\"、\"安排\"或\"打算\"的含义。这种用法比较生动,给人一种期待感。它常表示最近或较近的将来,所使用的动词多是转移动词。如: I\'m going. 我就要走了。 We\'re leaving for Beijing tomorrow. 我们明天就去北京。 When are you starting? 你们什么时候动身?

初中一般现在时与现在进行时语法详解及习题

一般现在时 一、概述 一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性,它不表示特定时间内发生的事。 用法: 1)经常性、习惯性的动作或存在的状态。 e.g. I go to school on foot. He is very busy now. 2)表示主语的特征、性格、能力、爱好等。 e.g. He can swim. I work hard. I like watching TV. 3)表示客观真理 e.g. There are seven days in a week. The moon moves round the earth. 二、一般现在时的结构 时态的结构指的是动词的变化形式。一般现在时间有两种结构,一种是动词原形,用于主语为非第三人称时的情况;另一种为动词的第三人称单数形式,用于主语为第三人称时的情况。Eg1.We often get up early in the morning. Eg2.My father often gets up early in the morning. 三、谈谈“主语为三单,其后动词s添” 在一般现在时中,当主语为第三人称单数时,谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单,其后动词s添”。何谓第三人称单数?用一句话概括就是“非你、非我、非复数”,如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, China, my book, etc. Eg3.He sometimes goes to school by bike. Eg4.My father works in the hospital as a doctor. 四、动词第三人称单数变化规则 动词第三人称变化的规则与可数名词复数变化的规则相同。 规则一、一般在词尾加-s。 如:looks, puts. reads, sees, skis等。 规则二、以-o, -s, -x, -sh, -ch结尾的加-es。 如:goes, does, misses, passes, mixes, fixes, pushes, wishes, watches, teaches,等。 规则三、以辅音字母加y结尾的,变y为i,再加-es。注意一定是辅音字母加y才变,若是元音字母加y,则直接加-s。 如:fly→flies,try→tries,fry→fries,copy→copies buy→buys,enjoy→enjoys,play→plays,say→says,pay→pays五、

英语语法—现在进行时(基本)

现在进行时 现在进行时表示动作发生的时间是“现在”,动作目前的状态是“正在进行中”。所谓“正在进行中”,是指在谈到这件事的时候,这个动作还在进行中。至于它是什么时候开始的,什么时候会停下来,不是我们关心的。所以“正在进行时”的事件,可能发生几年了,也可能只有几分钟。仍在进行中这是“正在进行时”的关键所在。它是一件持续进行的事情。 定义: 现在进行时的定义:现在进行时表示现在或当前一段时间正在进行的动作。可以表示有计划的未来,也就是用现在进行时表示将来。 构成: 现在进行时的构成是:主语+be+v.ing〔现在分词〕形式 第一人称单数 I+am+doing+Sth. 第一人称复数 We+are+doing +Sth. 第二人称单(复)数Y ou+are+doing+Sth. 第三人称单数He(She,it)+is+doing+Sth. 第三人称复数They+are+doing +Sth. 肯定句:主语+be(is/am/are)+现在分词 否定句:主语+be(is/am/are)+not+现在分词 一般疑问句:be(is/am/are)+主语+现在分词 特殊疑问句:特殊疑问词+相应be动词+主语+现在分词+Sth

变化规则: 1.直接+ ing(例:sleep+ing sleeping) 2.去掉不发音的e+ing(例:bite-e+ing biting) 3.重读闭音节,且末尾只有1个辅音字母,双写辅音字母+ing (例:sit+t+ing sitting) 4.特殊变化:die-dying,lie-lying,tie-tying 5.不规则变化 句型构成: 现在进行时 助动词be 动词的现在分词(ing形式)。 be的变化 在现在时中,be 要根据人称代词和名词的单复数不同,而分别使用am/is/are,即:I am/he/she/it 包括单数名词和不可数名词用is,you/we/they 包括复数名词用are. 注意:be 动词在现在时里算作“助动词”,翻译正在进行时的时候,be不能解释为“是”,否则不通顺。它只是和现在分词一起构成“进行时”。 现在分词加ing的规则 现在分词是在动词后加上ing 构成。如:starting,working, coming, sitting 等都是现在分词。现在分词的变化规则是固定的,大家用心记一下就可以了。 (1)直接在谓语动词后加ing. 例如:going, starting, working. (2)去掉词尾不发音的e,再加ing. 例如leaving,dining.
