牌坊,也叫牌楼,古已有之 ,是中国所特有的文化标志之一。关于牌坊的最早记载见于《诗经》,那时称为“衡门”。“衡门”的结构是两根柱子架一根横梁。唐代,我国的城市都采用里坊制,城内被纵横交错的棋盘式道路划分为若干块方形居民区,这些居民区,唐代称为“坊”。坊是居民居住区的基本单位,“坊”与“坊”之间有墙相隔,坊墙中央设有门,以便通行,称为坊门。后来因为门没有太大的实际作用,于是老百姓也逐渐称这种坟门为“牌坊”。

牌坊的建筑材料多为木质的,也有石质的,琉璃的或砖砌的。木质的牌专多不延年,现存的有些仿古牌坟,看上去似木质的,实际是后人用钢筋水泥或钢管建造的。

北京现存最古老的牌坊是朝阳门外神路街牌坊,设置于东岳庙山门之前。东岳路始建于元文宗天历年间,有人说初建时,山门前就有牌坊,可能是木质的,到明万历三十五年,改建成一座三间四柱七棱的绿琉璃牌坊。雄峙若城朝,歇山顶,正春两端施吻。接顶正中饰火焰宝珠。北面石额为“永延帝祚”,南面石额为“秩祀岱宗”。相传多为明朝严蒿之笔墨,意为皇图永固,江山绵延。

首都博物馆大厅内现有一座古牌坊,被称作“品级最高的牌坊”。该牌坊是一座三间四柱的木质彩绘牌坊,原设置在历代商王庙的庙门外,牌坊旁置有一座石碑,上书“官员人等,至此下马”。早年,无论是多商品阶的官员,至此必须下马,步行者从牌坊下面走过。若不如此,就犯有欺君之罪,会被衙役收监的。牌坊上的题额是“景德街”三字。现在此街被称作阜内大街。这座牌坊于20世纪50年代被拆除,首都博物馆建成后,又把它重新竖立起来,供公从观赏。

文丞相祠牌坊坐落于现北京市东城区府学胡同。明洪武九年,北京按察司副使刘崧为纪念文天祥这位南宋民族英雄,在他被关押的地方建起了一座“文丞相祠”,并在祠堂所在道路的两端各立了一座牌坊,东口题“教忠坊”,西口题“育贤坊”。这两座牌坊成为弘扬文天祥的民族气节和凛然正气的象征。人们从牌坊下经过,无不满怀崇敬之情。

牌坊是历史悠久,具有丰富的文化内涵和独特的审美价值,困此,长期以来,在世界各地,牌坊是一形象化的标志已成为古老的中华文明和历史悠久的中国的象征。

a. The government is desperate to sell the most troubled of South Korea’s big companies to foreigners. This, ministers believe, is the best way to accelerate the corporate restructuring begun in the wake of the Asian financial crisis in 1997, and to clear the way for more sustainable economic growth.
b. GM’s deal with Daewoo Motor marks the end of an even longer and more painful process. Ford almost bought the car maker two years ago, but pulled out after deciding that Daewoo would be too hard to turn round.
c. Micron had offered to pay about MYM3.4 billion for Hynix’s core memory business, and to take a minority stake in the non—memory arm. Analysts predict that the government will put pressure on creditors to rescue a deal with Micron or seek a new buyer, as liquidation is too risky to contemplate in an election year.
d. This week, after months of on—off talks with foreign suitors, the government’s plans moved a big step forward, and then an equally big step back.
e. But GM has much work to do to rebuild Daewoo’s damaged brand image and domestic market share, which hovers around 10% after reaching a high of 37% in 1998. GM has to fill holes in product lines by introducing sport—utility and multi—purpose vehicles, says Nick Reilly, former chief executive of Vauxhall, GM’s British subsidiary, and chief—executive—designate of GM—Daewoo now that he has sealed the deal.
f. GM has struck a good deal. Together with various undisclosed partners, it will hold a 67% stake in a new company, tentatively named GM—Daewoo. The American car maker will pay MYM251m for its own stake of 42%, but it will also assume MYM573m of Daewoo Motor’s debts. The acquisition is a key part of GM’s global expansion. The company has been trying to strengthen its foothold in Asia for some time.
g. On April 30th General Motors (GM) signed a contract to buy the bankrupt Daewoo Motor. But on the same day, the board of Hynix, a cash—strapped memory—chip giant, shocked the markets by rejecting a proposed takeover by Micron Technology, an American competitor.
h. His management team can expect trouble from South Korea’s aggressive unions along the way. In a sign of things to come, the signing ceremony was moved to a secret location after a group of union activists occupied the hotel where it was due to take place.
i. Buying a presence in South Korea was seen as particularly urgent, since imports account for only 3% of the 1.5mcars sold in the country each year. GM hopes to use Daewoo’s production lines to make budget cars that will be sold under the Daewoo brand in most markets.
j. GM had been talking with Daewoo for over a year. It has agreed to buy two of the company’s four domestic car plants, a factory in Vietnam, a parts unit in the Netherlands and nine overseassales arms (all in Europe except one, in Puerto Rico of all places). Between them, the two domestic factories can churn out a combined 530,000 cars and 30,000 commercial vehicles a year.
