It作形式主语

It作形式主语和形式宾语,虽然是我们高中就学过的语法点,但在考研英语题型中,无论是在阅读还是翻译,常会考查该知识点。 一.it作形式主语。 英语中不定式、动名词、主语从句在作主语时主语往往显得很长,使整个句子看上去有点头重脚轻,这样就借助“it”来作形式上的主语,而把真正的主语移到句子后边去,使全句结构上前后平衡。“it”并无实际意义。It之后的谓语部分,可以是be+形容词,be+名词(词组),或be+过去分词等。 it 作形式主语,主要分为下列三种情况:不定式作主语、动名词作主语和名词从句作主语。具体分析如下: 一、不定式作真正主语主要用于下列句型: 1. It + is/was + adj./n.+ to do sth. A.名词作表语。主要有a pity, a pleasure, an idea等。 It is a good idea to think this way. 这样考虑问题是个好办法 除be外,其他动词也有跟名词的情况。例如: It seems a pity to waste the food. 浪费这些食物真可惜。 B. 形容词或形容词短语作表语。分两种情况: 1.下列形容词;kind,good,nice,clever,wrong,right,foolish,wise,unwise,stupid,rude,careless,cruel,brave ,naughty,polite,selfish等词作表语时,不定式前常可加一个由of引起的短语,来说明不定式指的是谁的情况。形容词表示不定式逻辑主语的特征,即形容词用来描述不定式行为者的性格、品行等。例如: It was foolish of you to leave school.你中途退学,真是傻瓜。 2. 其他形容词作表语,常见的形容词有:necessary, hard,important, difficult, easy, possible,common等。 It is necessary to learn English. 需要注意的是:动词不定式作主语,一般情况下用it作形式主语,而把动词不定式(从句)放在后面。也可以直接用不定式作主语。例如: It is wrong to tell lies. = To tell lies is wrong. 撒谎是不对的。 但在疑问句和感叹句中,只能用it作形式主语。例如:

英汉翻译评析(附参考译文)

英汉翻译讲解(1) I.英汉之间的差别: “对于中国学生最有用的帮助是让他认识英语和汉语的差别。”------吕叔湘 国内学者的共识是:汉语是综合性的,描写性的,而英语是分析性的,逻辑性的。在语言学上最重要的区别在于形合和意合的对比(contrast between hypotaxis and parataxis),英语重形合(形式上的融合),汉语重意合(意思或意境的融合)。在句法方面,有学者形象地把英汉比喻为以下几种: 1.雄孔雀/雄狮-----即英语习惯于把最着重的事物放在句首先说出来,开门见山,一语破的,然后再把各种标志一条条补述,一步步交代,慢条斯理,从容不迫,形成一条头短尾长地线性链,象头小尾大地雄孔雀。而汉语则相反,其线性序列的展开好比画龙点睛,先把外围的环境与衬托一一交代周到,最后点出话语的信息中心,水到渠成,给人以豁然开朗之感,形成雄狮型头大尾小地局式。 例如:I was all the more delighted when, as a result of the initiative of your Government it proved possible to reinstate the visit so quickly. 译文:由于贵国政府的提议,才得以这样快地重新实现访问。这使我感到特别高兴。 又如:The assertion that it was difficult, if not impossible, for a people to enjoy its basic rights unless it was able to determine freely its political status and to ensure freely its economic, social and cultural development was now scarcely (不足地,不充分地;一定不,绝不)contested (斗争;比赛). 译文:如果一个民族不能自由地决定其政治地位,不能自由地保证其经济、社会和文化的发展,要享受其基本权利,即使不是不可能,也是不容易的。这一论断几乎是无可置辩的了。 2.葡萄/竹竿-----即把英语句子比作“葡萄型”结构,葡萄主干很短,其上附结着丰硕的果实。而汉语句子则较短,一个短句接一个短句地往下叙述,逐步展开,内容像竹竿一样一节一节展开,常称为“竹竿型”结构。 She was beautiful, with long dark hair and brilliant green eyes.她长得很美,一头乌黑亮丽的长发,一双晶莹明亮的绿色眼睛。 She has smooth akin as pale and iridescent as the moon shining over a snow-covered landscape.她光滑的肌肤白里透红,宛如皎洁的月光洒在茫茫血地上。 3.多枝共干----英语句子中还有两个或几个动词共受一个状语修饰,共有一个主语或宾语,或者两个或几个状语共同修饰一个动词,两个或几个主语或宾语共一个动词,这就好比几根树枝长在同一根树干上,我们称为“多枝共干”式结构。 4.也有学者认为英语是一种弥漫着“男子气”的语言。逻辑性、组织性和理性是以英语为母语的民族的思维支撑点,从而就形成了英语的“阳刚之美”。而汉语自有汉语之美。汉语不注重对客观现实作符合逻辑的形式的描摹,不执着于形式结构的规范,中国人的思维支撑点似乎更具有抽象,深邃和疏放的取向,由此繁衍生出的是显赫的暗示和幽远的意境从而形成汉语的“阴柔之美”。汉语的魅力在于她的流散和疏放,系于她超凡的暗示力和意境性。所以汉语的形式机制很弱,主谓宾没有形式标定,主谓间关系松散,宾语无定格,无定位,主语的超句承接功能很强。 如果说汉语是一种“人治”语言,那么,英语则是一种“理性”语言。汉语能化逻辑为内在,英语则必须将逻辑外化,化作种种行合的标记,化作启转承合的纽带。英语语法规范森严,理性十足;英语形式逻辑缜密,滴水不漏。 5.汉语是一种意境语言,一种艺术语言。寥寥数词,就能出意境,出氛围,出画面。

C++中explicit关键字的作用

C++中explicit关键字的作用 explicit用来防止由构造函数定义的隐式转换。 要明白它的作用,首先要了解隐式转换:可以用单个实参来调用的构造函数定义了从形参类型到该类类型的一个隐式转换。 例如: class things { public: things(const std::string&name = ""): m_name(name),height(0),weight(10){} int CompareTo(const things & other); std::string m_name; int height; int weight; }; 复制代码 这里things的构造函数可以只用一个实参完成初始化。所以可以进行一个隐式转换,像下面这样: things a; ................//在这里被初始化并使用。 std::string nm = "book_1"; //由于可以隐式转换,所以可以下面这样使用 int result = https://www.docsj.com/doc/e32445964.html,pareTo(nm); 复制代码 这段程序使用一个string类型对象作为实参传给things的CompareTo函数。这个函数本来是需要一个tings对象作为实参。现在编译器使用string nm来构造并初始化一个things对象,新生成的临时的things对象被传递给CompareTo函数,并在离开这段函数后被析构。 这种行为的正确与否取决于业务需要。假如你只是想测试一下a的重量与10的大小之比,这么做也许是方便的。但是假如在CompareTo函数中还涉及到了要除以初始化为0的height 属性,那么这么做可能就是错误的。需要在构造tings之后更改height属性不为0。所以要限制这种隐式类型转换。 那么这时候就可以通过将构造函数声明为explicit,来防止隐式类型转换。

It”作形式主语和形式宾语用法详解

新希望英语语法精讲------“I t”作形式主语和形式宾语“It”作形式主语和形式宾语的用法详解 It作形式主语和形式宾语用法,是英语学习的主要语法项目之一。无论是单项选择,还是完行填空,it用法始终是反复考查的重、热点之一。现将it在特殊句型中作形式主语和形式宾语用法,进行如下归纳分析,以供学习参考。一、 It 用作形式主语当不定式(短语)、动名词(短语)或从句在某个句子中作主语时,为保持句子结构前后平衡,避免头重脚轻,因此常用it作形式主语置于句首,而将真正的主语放在句尾。此时it只起先行引导作用,本身无词义。 e.g. It is wrong to tell a lie. (说谎是错误的。) 〔It为to tell a lie 的形式主语〕 It is no use arguing about it. (争吵是没用的。) 〔It为arguing about it的形式主语〕 It is uncertain who will come. (谁要来还不确定。) 〔It为who will come 的形式主语〕 It 作形式主语的常见句型: ① It + be + 形容词 + to do sth. / doing / that …. e.g. It is very important to learn a foreign language. (学一门外语非常重要。) It is useless crying over the spilt milk. (覆水难收。)

It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。) ② It + be +名词词组 + doing / that …. e.g. It is no good telling lies. (撒谎没好处。) It is a pity that you didn’t go to see the film yesterday. (你昨天没看成那部电影真遗憾。) It is a truth that there would be no new China without the Communist Party. (没有共产党就没有新中国,这是毋庸质疑的。) ③ It + be + 过去分词 + that …. 该句型常见动词有:say, hope, think, suppose, expect, report, know, believe, decide, etc. e.g. It is said that they have invented a new type of computer. (据说他们发明了一种新型电脑。) It is believed that China will become one of the strongest countries in the world. (大家都相信中国将会步入世界强国之列。) It was reported that more than 170 thousand people died in the 2004 tsunami. (据报道,至少有十七万人在2004年那场海啸中丧生。) ④ It + seems / appears / happens等不及物动词 + that ….

Commentaries on the Version of “一个女人是这样衰老的” 一个女人是这样衰老的 SV:How a Woman Ages/A Woman’s Aging/A Woman Fades Thus/What causes a Woman to Grow Old/The Way in Which a woman is Aging/How a Woman Gets Old RV: The Way Woman Withers 点评:Rhetorical Device: distillation and aesthetic hightlights of language, either Chinese or English/The successful employment of alliteration(头韵) 1.二十岁的时候,我穿着一条背心式牛仔裙在校园里走来走去,一说话就脸红。三十岁的我穿着名牌套装,坐在办公桌前,满脸冷酷地对下属说:“这么愚蠢的问题你也敢问?也不先打个草稿。”SV: At the age of twenty, I walked about on the campus, wearing a vestlike jean skirt. My face would turn red whenever I speak. After I have turned thirty, I am seated in front of a bureau, in a suit of famous brand, reproaching a subordinate coldly “How dare you ask such a stupid question? Why didn’t you make a draft first?” RV: At the age of twenty, wearing a jeans jumper, I moved about on the campus, my face blushing the moment I had the inclination to make an

认识 C++ 中的 explicit 关键字

认识C++ 中的explicit 关键字 (Danny Kalev发表于2004-12-28 11:01:04) 带单一参数的构造函数在缺省情况下隐含一个转换操作符,请看下面的代码: class C { int i; //... public: C(int i);//constructor and implicit conversion operator //as well }; void f() { C c(0); c = 5; //将5 隐式转换为C 对象,然后赋值 } 编译器重新编辑上述例子代码,如下: ////////////////////////////////////////////////////////////////////////////////////////// //"c=5;" 被编译器转换成下面这个样子: ///////////////////////////////////////////////////////////////////////////////////////// C temp(5);// 实例化一个临时对象, c = temp; // 用= 赋值 temp.C::~C(); // temp 的析构函数被激活 在很多情况下,这个转换是有意的,并且是正当的。但有时我们不希望进行这种自动的转换,例如: class String { int size; char *p; //.. public: String (int sz); //这里不希望进行隐式转换操作 }; void f () { String s(10); // 下面是一个程序员的编码;发生一个意想不到的转换:

翻译中的英汉八大不同解析

翻译中的英汉八大不同 一、英语重结构,汉语重语义 我国著名语言学家王力先生曾经说过:“ 就句子的结构而论,西洋语言是法治的,中国语言是人治的。”(《中国语法理论》,《王力文集》第一卷,第 35页,山东教育出版社, 1984年 我们看一看下面的例子: Children will play with dolls equipped with personality chips, computers with inbuilt personalities will be regarded as workmates rather than tools, relaxation will be in front of smell television, and digital age will have arrived. 译文:孩子们可以和装有性格芯片的娃娃一起玩耍;内嵌性格装置的电脑将被视作人们工作上的伙伴而不仅仅是工具; 休闲时, 电视机还能满足人们嗅觉感官的需求——那时, 数码时代就已经到来了。 这句英语是由四个独立句构成的并列句,前三个句子都用简单将来时, 最后一个句子用的是将来完成时, 句子之间的关系通过时态、逗号和并列连词 and 表示得一清二楚。而汉语译文明显就是简单的叙述, 至于句子之间的关系完全通过句子的语义表现出来:前三个句子可以看成是并列关系,最后一个句子则表示结果。 二、英语多长句,汉语多短句 由于英语是“ 法治” 的语言,只要结构上没有出现错误,许多意思往往可以放在一个长句中表达;汉语则正好相反,由于是“ 人治” ,语义通过字词直接表达,不同的意思往往通过不同的短句表达出来。正是由于这个原因, 英译汉试题几乎百分之百都是长而复杂的句子,而翻译成中文经常就成了许多短小的句子。 例如:Interest in historical methods had arisen less through external challenge to the validity of history as an intellectual discipline and more from internal quarrels among historians themselves.

初中英语语法:it用作形式主语的用法

初中英语语法:it用作形式主语的用法 一、基本用法 当不定式、动名词、从句等用作主语时,避免头重脚轻,通常在句首使用形式主语it,而把真正的主语放在句子末尾: Is it necessary to tell his father everything? 有必要把这个切都告诉他父亲吗? It’s no good sitting up too late. 熬夜没有好处。 It is quite clear that he has read the book. 很显然,他读过这本书。 It doesn’t matter what he says. 他说什么没关系。 二、几种特殊的形式主语 (1) 用作动词look, seem, appear, happen, occur, follow等的主语(后接that从句或as if从句): It seems as if it is going to rain. 看来要下雨了。 It seems that he knows everything. 他好像什么都知道。 It (so) happened that I had no money with me. 碰巧我没带钱。 From this witness it follows that he must be guilty. 根据该证人的证词判断,他一定有罪。 (2) 当系表结构后接有if 或when引出的状语从句时,通常在系表结构前使用形式主语表示说话人对某情况的看法: It was a great surprise to me when he did a thing like that. 他这样做使我很吃惊。

c++中的explicit关键字用来修饰类的构造函数,表明该构造函数是显式的,既然有"显式"那么必然就有"隐式",那么什么是显示而什么又是隐式的呢? 如果c++类的构造函数有一个参数,那么在编译的时候就会有一个缺省的转换操作:将该构造函数对应数据类型的数据转换为该类对象,如下面所示: class MyClass { public: MyClass(int num); } .... MyClass obj=10;//ok,convert int to MyClass 在上面的代码中编译器自动将整型转换为MyClass类对象,实际上等同于下面的操作: MyClass temp(10); MyClass obj=temp; 上面的所有的操作即是所谓的"隐式转换". 如果要避免这种自动转换的功能,我们该怎么做呢?嘿嘿这就是关键字explicit的作用了,将类的构造函数声明为"显示",也就是在声明构造函数的时候前面添加上explicit即可,这样就可以防止这种自动的转换操作,如果我们修改上面的MyClass类的构造函数为显示的,那么下面的代码就不能够编译通过了,如下所示: class MyClass { public: explicit MyClass(int num);

} .... MyClass obj=10;//err,can‘t non-explict convert class isbn_mismatch:public std::logic_error{public:explicit isbn_missmatch(const std::string &s):std:logic_error(s){}isbn_mismatch(const std::string&s,const std::string&lhs,const std::string &rhs):std::logic_error(s),left(lhs),right(rhs){}const std::string left,right;virtual~isbn_mismatch() throw(){}}; Sales_item&operator+(const Sales_item&lhs,const Sales_item rhs){if(!lhs.same_isbn(rhs)) throw isbn_mismatch("isbn missmatch",lhs.book(),rhs.book());Sales_item ret(lhs);ret+rhs;return ret;} Sales_item item1,item2,sum;while(cinitem1item2){try{sun=item1+item2;}catch(const isbn_mismatch&e){cerre.what()"left isbn is:"e.left"right isbn is:"e.rightendl;}} 用于用户自定义类型的构造函数,指定它是默认的构造函数,不可用于转换构造函数。因为构造函数有三种:1拷贝构造函数2转换构造函数3一般的构造函数(我自己的术语^_^) 另:如果一个类或结构存在多个构造函数时,explicit修饰的那个构造函数就是默认的 class isbn_mismatch:public std::logic_error{public:explicit isbn_missmatch(const std::string &s):std:logic_error(s){}isbn_mismatch(const std::string&s,const std::string&lhs,const std::string &rhs):std::logic_error(s),left(lhs),right(rhs){}const std::string left,right;virtual~isbn_mismatch() throw(){}}; Sales_item&operator+(const Sales_item&lhs,const Sales_item rhs){if(!lhs.same_isbn(rhs)) throw isbn_mismatch("isbn missmatch",lhs.book(),rhs.book());Sales_item ret(lhs);ret+rhs;return ret;}
