3.代替某些代词 代词it 还可用于代替指示代词this, that 以及复合不定代词something, anything, nothing等。如: “What’s this?”“It’s a new machine. ”“这是什么?”“是一种新机器”。 Nothing is wrong, is it? 没出什么问题,是吗? 二、it 作非人称代词的用法 1.基本用法 it 作非人称代词的用法,主要用于指时间、距离、价值、天气、气候及温度等自然现象。如: It’s too late to go there now. 现在去那儿已经太迟了。 It rained all day yesterday. 昨天下了一天的雨。 It can get very hot here. 这里有时会很热。 2.用于某些句型 It’s time for sth. 该做某事了。 It’s time to do sth. 该做某事的时候了。 It’s time for sb to do sth. 某人该干某事了。 It’s (about / high) time + that-从句. 某人该做某事了。(从句谓语用过去式,有时也用“should+动词原形”) It’s first (second) time + that-从句. 某人第几次干某事。(从句谓语用现在完成时)

“的、地、得”用法分析及练习(后附答案)

“的、地、得”用法分析及练习(后附答案) 一、的、地、得用法分析: “的”后面跟的都是表示事物名称的词或词语,如:敬爱的总理、慈祥的老人、戴帽子的男孩、珍贵的教科书、鸟的天堂、伟大的祖国、有趣的情节、优雅的环境、可疑的情况、团结友爱的集体、他的妈妈、可爱的花儿、谁的橡皮、清清的河水...... “地”后面跟的都是表示动作的词或词语,如:高声地喊、愉快地唱、拼命地逃、疯狂地咒骂、严密地注视、一次又一次地握手、迅速地包围、沙沙地直响、斩钉截铁地说、从容不迫地申述、用力地踢、仔细地看、开心地笑笑......” “得”前面多数是表示动作的词或词语,少数是形容词;后面跟的都是形容事物状态的词或词语,表示怎么怎么样的,如:走得很快、踩得稀烂、疼得直叫唤、瘦得皮包骨头、红得发紫、气得双脚直跳、理解得十分深刻、乐得合不拢嘴、惊讶得目瞪口呆、大得很、扫得真干净、笑得多甜啊...... 二、的、地、得用法补充说明: 1、如果“de”的后面是“很、真、太”等这些词,十有八九用“得”。 2、有一种情况,如“他高兴得一蹦三尺高”这句话里,后面的“一蹦三尺高”虽然是表示动作的,但是它是来形容“高兴”的程度的,所以也应该用“得”。

三、的、地、得用法总结: 1、“的”前面的词语一般用来修饰、限制“的”后面的事物,说明“的”后面的事物怎么样。结构形式一般为:修饰、限制的词语+的+名词。 2、“地”前面的词语一般用来形容“地”后面的动作,说明“地”后面的动作怎么样。结构方式一般为:修饰、限制的词语+地+动词。 3、“得”后面的词语一般用来补充说明“得”前面的动作怎么样,结构形式一般为:动词(形容词)+得+补充、说明的词语。 四、的、地、得用法例句: 1. 蔚蓝色的海洋,波涛汹涌,无边无际。 2. 向日葵在微风中向我们轻轻地点头微笑。 3. 小明在海安儿童公园玩得很开心。 五、“的、地、得”的读音: “的、地、得”是现代汉语中高频度使用的三个结构助词,都起着连接作用;它们在普通话中都各自有着各自的不同的读音,但当他们附着在词,短语,句子的前面或后面,表示结构关系或某些附加意义的时候都读轻声“de”,没有语音上的区别。 但在书面语中有必要写成三个不同的字,这样可以区分他们在书面语用法上的不同。这样做的好处,就是可使书面语言精确化。

标点符号用法分析

标点符号用法 一、标点符号 标点符号:辅助文字记录语言的符号,是书面语的有机组成部分,用来表示语句的停顿、语气以及标示某些成分(主要是词语)的特定性质和作用。 句子:前后都有较大停顿、带有一定的语气和语调、表达相对完整意义的语言单位。 复句:由两个或多个在意义上有密切关系的分句组成的语言单位,包括简单复句(内部只有一层语义关系)和多重复句(内部包含多层语义关系)。 分句:复句内两个或多个前后有停顿、表达相对完整意义、不带有句末语气和语调、有的前面可添加关联词语的语言单位。 陈述句:用来说明事实的句子。 祈使句:用来要求听话人做某件事情的句子。 疑问句:用来提出问题的句子。 感叹句:用来抒发某种强烈感情的句子。 词语:词和短语(词组)。词,即最小的能独立运用的语言单位。短语,即由两个或两个以上的词按一定的语法规则组成的表达一定意义的语言单位,也叫词组。 二、分类 标点符号分为点号和标号两大类。

点号的作用是点断,主要表示说话时的停顿和语气。点号又分为句末点号和句内点号。 句末点号用在句末,表示句末停顿和句子的语气,包括句号、问号、叹号。 句内点号用在句内,表示句内各种不同性质的停顿,有逗号、顿号、分号、冒号。 标号的作用是标明,主要标示某些成分(主要是词语)的特定性质和作用。包括引号、括号、破折号、省略号、着重号、连接号、间隔号、书名号、专名号、分隔号。 (一)句号 1.用于句子末尾,表示陈述语气。使用句号主要根据语段前后有较大停顿、带有陈述语气和语调,并不取决于句子的长短。 2.有时也可表示较缓和的祈使语气和感叹语气。 请您稍等一下。 我不由地感到,这些普通劳动者也是同样值得尊敬的。 (二)问号 主要表示句子的疑问语气。形式是“?”。 1.用于句子末尾,表示疑问语气(包括反问、设问等疑问类型)。使用问号主要根据语段前后有较大停顿、带有疑问语气和语调,并不取决于句子的长短。 2.选择问句中,通常只在最后一个选项的末尾用问号,各个选项之间一般用逗号隔开。当选项较短且选项之间几乎没有停顿时,选项之间可不用逗号。当选项较多或较长,或有意突出每个选项的独立性时,也可每个选项之后都用问号。 3.问号也有标号的用法,即用于句内,表示存疑或不详。 马致远(1250?―1321)。 使用问号应以句子表示疑问语气为依据,而并不根据句子中包含有疑问词。当含有疑问词的语段充当某种句子成分,而句子并不表示疑问语气时,句末不用问号。

The package (which / that)you are carrying is about to come unwrapped. ^ (which / that在从句中作宾语,可省略) 关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。 eg.

Do you know the day when they arrived? The reason why he refused is that he was too busy. 注意: 1)关系副词常常和"介词+ which"结构互换 eg. There are occasions when (on which)one must yield (屈服). Beijing is the place where(in which)I was born. Is this the reason why (for which)he refused our offer? * 2)在非正式文体中,that代替关系副词或"介词+ which",放在时间、地点、理由的名词,在口语中that常被省略。 eg. His father died the year (that / when / in which)he was born. He is unlikely to find the place (that / where / in which)he lived forty years ago.

基于语料库的“人家”用法分析

基于语料库的“人家”用法分析 “人家”是北方方言中口语化的指称代词,语义非常丰富。不同的指称用法蕴含说话人不同的情感态度,如称羡讽刺、同情自怜,从而达到不同的语用效果,即语用移情或语用离情的效果。本文借助于语料库,为分析“人家”的用法及语用效果提供了科学的支撑和有力的支持。 标签:“人家” 语用效果语用功能 一、引言 “人家”既可以用作旁指代词,虚指除自己以外的“别人”,又可以用作第三人称代词,实指“他”或“他们”,也可以和“人家”后面的名词性成分构成同位语,有复指的用法。此外,“人家”还可以用来指称自己或是听话人“你”或“您”。“人家”有如此丰富的指称用法蕴含了说话人怎样的情感态度?本文从语用学的角度,借助语料库这一工具对“人家”一词的用法进行具体分析。 (一)研究内容 本文要探讨的问题如下:1.“人家”的具体用法有哪些?哪些常用,哪些不常用?2.“人家”在不同的语境、不同的用法中主要表达说话人怎样的情感态度? 3.“人家”在使用中语用移情功能多还是语用离情功能多? 笔者认为,“人家”不同指称义的使用,直接体现着言者对不同人际关系的评判,蕴含着言者不同的情感态度。过去对“人家”的研究主要集中在句法层面和语义层面,从语用层面进行分析研究的相对匮乏,并且大多只是从少量例子出发,作出概括分析,带有强烈的主观色彩。因此借用语料库这一工具,对“人家”的用法及语用效果进行科学客观的分析,是本文的根本出发点。 (二)研究方法 本文首先利用国家语委现代汉语平衡语料库检索出1794个包含“人家”的语料。其次,利用Concordance Sampler抽样软件,抽取出500个样本逐个进行分析,剔除不符合条件的名词用法,剩余404个“人家”作代词的语料。再次,通过人工标记的方法,按照指称对象的不同,对“人家”的用法进行分类。最后,由于“人家”的基本义“别人”使用时比较客观,不带感情色彩,因而笔者对“人家”其余四种用法的166个语料一一分析了其表达的说话人的情感倾向,进而分析其语用表达效果。 二、“人家”的用法分析 “人家”的归属问题,历来备受争议。本文综合各家之言,将“人家”的用法分为5类:1.旁指;2.复指;3.第一人称;4.第二人称;5.第三人称。通过对所得语

虚词“了”的用法分析

虚词“了”的用法分析 摘要:现代汉语中,虚词“了(le)”不论是在口语中,还是书面语中,使用频 率都比较高。虚词“了”有两个,语气词“了”和助词“了”。两者字形、读音相同,但具体用法和语法作用却不相同。 关键字: 虚词“了”、语气词、助词、具体用法、语法作用 正文: 注意:语气词“了”和助词“了”可同在句末。且都在句子末尾,可能是助词“了”,也有可能是语气词“了”,但意思有区别。 如:她写了。(“了”若是语气词,则表示动作在进行,若“了”是助词,则表示动作已经完成) 一、助词“了”。 1.紧跟在动词之后,表示动作的完成。 如:1)王春生从来没有忘了他爹的惨死跟妈的眼泪。(周立波《暴风骤雨》) 2)还没有等到发榜,全国高校统考开始了,我当然还应该参1《谈谈句末的“了”》张兰英-《东岳丛林》-2005

加。(余秋雨《霜冷长河》) 也可以表示将要发生的事情或假设可能发生的事情的完成。如:跟他们谈话就是我的工作,你要有什么话等我闲了再谈吧。(《赵树理选集》) 2.如果动词之后紧跟着另外一个动词或形容词作补语时,“了”就放在了补语之后。 如:1) "祥哥!"她往前凑了凑,"我把东西都收拾好了。"(老舍《骆驼祥子》) 2)他决定去拉车,就拉车去了。(老舍《骆驼祥子》) 3) 整整的三年,他凑足了一百块钱!(老舍《骆驼祥子》) 3. “了”放在由两个动词构成的并列词组后面(表示两个动词同时或者连续完成)。 如:这项政策的实施进一步巩固和加强了海内外中华儿女大团结。 4. 连谓句、兼语句中,助词“了”一般用在后一动词之后2。如:她找我借了两本书。连谓句强调前一动作完成后才开始后一动作时,兼语句前一动作完成时,助词“了”可在前一动词后。如:临时组织了一些人去支援五车间。 5. 有些动词后面的助词“了”表示动作有了结果,即加在动词后面的“掉”很相似。这类动词有:泼、扔、放、碰、砸、捧、磕、撞、踩、伤、杀、宰、切、冲、卖、还、毁、忘、丢、关、喝、吃、咽、吞、涂、抹、擦等。这个意义的“了”可以用在命令句和‘把’字句。2吕叔湘《现代汉语八百词》(1981商务印书馆)第315页。
