篇9:Under the Rose

Under the Rose秘密地;私下得;暗中

Under the rose直译“在玫瑰花底下”,而实际上却表示in secret; privately confidentially的意义,语言外壳与内涵,似乎风马牛不相及.它源自古罗马的神话故事和欧洲的风尚.

罗马神话中的小爱神丘比特(Cupid),也称希腊神话里的厄洛斯(Eros),在文艺作品中以背上长着双翼的小男孩的形象出现,常携带弓箭在天空中遨游,谁中了他的金箭就会产生爱情.丘比特是战神玛斯(Mars)和爱与美之神维纳斯(venus)所生的儿子.维纳斯,也就是希腊神话里的阿芙罗狄蒂(Aphrodite),传说她是从大海的泡沫里生出来,以美丽著称,从宙斯到奥林匹帕斯的诸神都为起美貌姿容所倾倒.有关她的恋爱传说很多,欧洲很多文艺作品常用维纳斯做题材.小爱神丘比特为了维护其母的声誉,给沉默之神哈伯克拉底(Harpocrates)送了一束玫瑰花,请他守口如瓶不要把维纳斯的风流韵事传播出去.哈伯克拉底受了玫瑰花就缄默不语了,成为名副其实的“沉默之神”

古罗马人对维纳斯非常尊崇,不仅奉为掌管人类的爱情.婚姻.生育的爱与美的神,而且尊为丰收女神.园艺女神.罗马的统治者恺撒大帝甚至追搠维纳斯是罗马人的祖先.由于上述神话传说,古罗马人把玫瑰花当作沉没或严守秘密的象征,并在日常生活中相尚成风.人们去串门做客,当看到主人家的桌子上方画有玫瑰,客人就了解在这桌上所谈的一切行为均不应外传.于是在语言中产生了Sub rosa在玫瑰花底下这个拉丁成语. 据<牛津英语词典>解释,英语under the rose系源自德语unter der Rosen.

古代德国的宴会厅.会议室以及旅店的餐室,在天花板上常画有或雕刻着玫瑰花,用来提醒在场者要守口如瓶,严守秘密,不要把玫瑰花底下的言行透露出去.这个流行于15至17世纪的德语成语反映了这种习俗.

罗马帝国全盛时,其势力几乎席卷了整个欧洲,罗马某些文化风尚也随着他的军事力量渗透到欧洲各国.因此,以玫瑰花象征沉默的习俗,并不限于德国

under the rose 是个状语性成语,在句中修饰动词,其含义因所修饰的动词的不同而略有不同.如:born under the rose“私生的”“非婚生的”;do under the rose“暗中进行”

eg:The senator told me under the rose that there is to be a chance in the cabinet

The matter was finally settled under the rose.

Do what you like undeer the rose,but don't give a sign of what you're about...;

篇10:under是什么意思

例句:

They feel under permanent threat.

他们感觉处在持续不断的威胁之下。

She dived under the water.

她潜入水下。

If it's not under 'sports', try looking under 'games'.

如果在“体育运动”项下查不到,就试试“游戏”项吧。

篇11:below; under辨识

below; under

这两个介词都有“在……下面”的意思,表示数量多少时,两者可以通用。例如:

He is below/under fifty. 他不到五十岁。

below指位置低于某物或在某物的下方,但不一定在正下方,其对应词是above; under指在某物的正下方,对应词是over。例如:

50 metres below sea level. 低于海平面50米。

below还可指价值、地位、等级、温度等“低于……”,也可表示“在下游”;under还可用于修饰抽象的事物,意为“在……(领导、管辖、统治等)之下”。例如:

He was below her in intelligence. 他的智力比她差。

篇12:or和and用法总结

and和or的用法:

1、and和or的用法并列结构中,or通常用于否定句,and用于肯定句。但有时and 也可用于否定句。

2、在否定中并列结构用or 连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。

3、or用于连接并列的单词、词组、短语或句子,表示“或者”的意思。or用在选择疑问句中,灵活译为“还是”。or用于否定句中,代替and ,表示“和”的意思。

4、or用于连接两个并列的句子,表示“否则,要不然”的意思。

(2)on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如:

a house on the main road 临大街的房子,sit on my right 坐在我的`右边

(3)on表示状态,译为“处于.情况中,从事于.”等.如:

on duty 值日,on holiday 度假

(4)on表示“在.上面”,用在表示物体的名词前.如:

on the box 在盒子上

on和over都是介词,on表示“在.上面”,指一物体与另一物体表面相接触;over表示“在.上方”,指一物体与另一物体不接触.试比较:

There is a light on the desk.桌子上有盏台灯.(light与desk接触)

There is a light over the desk.桌子上方有一盏灯.(light与desk不接触)

表示“在.上”,介词on与in必须注意习惯用法,否则会出错.不妨比较一番:

on the tree/in the tree都译为“.在树上”.前者表示树上本身所长着的叶子、花、果实等;后者表示某物或某人在树上.

on the wall/in the wall都译为“在墙上”.由于介词不同,在使用上有区别.图画、黑板、风筝等“在墙上”,是因为它们在墙的表面上,故用on the wall;门窗、钉子、洞、孔等“在墙上”,是因为它们在墙的里面,故用in the wall.

篇15:THAT用法总结

“that”在英文中是一个使用频率很高的单词。它有四种词性,并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法,很可能会形成英语学习的一种障碍,从而影响其学习兴趣和效率。现将that的用法总结归纳如下:

that is what he told me.

what is that (which) you have got in your hand?

the price of rice is higher than that of flour.

2. that 用作关系代词,引导限制性定语从句。先行词可人可物,用法相当于who或which。(但是在下列情况下多用that:先行词既有人又有物时;先行词有形容词最高级、序数词、不定代词、very,only等修饰时;先行词是不定代词时)

Try as he might,Tom could not get out of the difficulties.不管怎样努力,汤姆还是摆脱不了困境。

四)as作关系代词。

1.引导限制性定语从句,用在“such...as”,“the same...as”,“as...as”等结构中,常译作“像...一样的人(或物)”,“凡是...的人(或物)”。例eg:

He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。

My hometown is no longer the same as it was.我的家乡再也不像过去一样了。

2.引导非限制性定语从句,用来指代它前面的整个句子(即先行句),意思是“这一点”。这个分句可以位于句首、句中或句末。eg:

As is well known,oceans cover more than 70% of the earth.我们知道,海洋占地球面积的百分之七十以上。
