问题 问答题

A、B、C、D、E是五种常见的物质.通常情况下.A、B为气体,C、D、E、液态.C是生命之源,人们每天都必须用它.试管中将D.微微加热,可缓慢生成C和气体A.若在加入少量二氧化锰时反应速率会加快,气体A能使带火星的小木条复燃;B 在自然界中含量升高能引起温室效应.且能使澄清的石灰水变浑浊;E是一些饮料的主要成分,同时又是实验室常用的燃料.请你判断.A、B、C、D、E、各是什么物质(用物质名称填写)

A______B______C______D______E______.

答案

C是生命之源,因此C是水;试管中将D.微微加热,可缓慢生成C和气体A.若在加入少量二氧化锰时反应速率会加快,气体A能使带火星的小木条复燃,因此A是氧气,则D是过氧化氢;B 在自然界中含量升高能引起温室效应,且能使澄清的石灰水变浑浊,因此B是二氧化碳;E是一些饮料的主要成分,同时又是实验室常用的燃料,因此E是酒精;

故答案为:氧气;二氧化碳;水;过氧化氢;酒精.

岁月河流上的码头(节选)

  (1)一年的日子,仿佛是一条长长的河流,缓缓地、平静地流淌。每个季节,便是河流上不同的河段。

  (2)但这样说未免还是浮泛了些。须知天下的季节都是一样的,赤道南北,半球东西,当岁月之河从某一片土地上流过时,是什么使得它和其他地方的河流不同?是船上的风帆,是波涛的颜色,还是飘荡在水面上的歌声?

  (3)对于这一片古老的、被称为华夏的、我祖先的土地,时光有着许多呈现自己的方式。其中之一,便是借助一系列独特的民俗节日。

  (4)被称为中国人三大节 日的春节、端午和中秋,我们已经耳熟能详。其他节日,名气虽然不如它们,但每一个也都有着丰厚的内涵和独特的魅力。

  (5)正月的背影刚刚遁去,煮元宵的香甜糯软尚在回味之中,便走近了又一个节日:二月二。“二月二日新雨晴,草芽菜甲一时生”。这个时节,阳气萌发,气温升高,降雨增多,土地变得润泽松软,适宜播种。

  (6)当岸边蒲苇繁茂、草木飘香时,我们知道,已经接近了被称为七夕节、又名乞巧节或女儿节的日子。牛郎织女的传说,将农历七月七这天,装扮得温柔旖旎。这个晚上,未嫁的女儿家,要向织女乞求赐以聪慧的心灵和灵巧的双手,以及美满的姻缘。

  (7)“独在异乡为异客,每逢佳节倍思亲。遥知兄弟登高处,遍插茱萸少一人。”吟诵着王维的诗句,菊花的清香在幻觉中徐徐飘拂过来,九九重阳节来临了。遥想故土山水佳胜之地,定是亲朋团聚,言笑晏晏,唯独自己天涯羁旅,孑然一身,能不黯然?亲情惘惘,系念依依,这其间的深情厚意,岂是电子邮件、手机短信能够表达和传递的?

  (8)继续泛舟漂流,渐渐木叶脱尽,霜雪时作,江天寥廓。然而尽管风景萧索,空气里却悄悄酝酿着一种欢欣,传递出一种暖意。腊八节,古代庆祝丰收、感谢祖先和神灵、驱逐瘟疫的祭祀仪式,在农历十二月初八这一天,欢快登场。

  (9)清明节、中元节、冬至节……古老的民俗节日还有很多,它们的起源,都和土地、和农耕时代的生活、和先民朴素的梦想有关。在形成和流传的过程中,又渐次衍生出更为丰富的内容,仿佛村口一棵百年的榕树,向四周伸展出众多气根和分枝,独木成林,几乎遮蔽了数条街巷。

  (10)如果说,岁月的累积形成了历史,那么,这样的日子的反复叠加,就是在参与一个种族、一种文化的构建。当它们千百年来,被这块土地上的一辈辈子民们,经由文字的或口头的方式代代传递,而逐渐累积成为一种公共记忆时,便也是在铸造某种民族的精神和文化的基因,使人产生集体的身份认同和共同的历史归属感。这是一种不露声色的渗透,润物无声,在我们懵懂无知的童年,已经潜移默化地进入血脉,左右了我们的思维、行动的方式和路径

  (11)今天,地球已经成为一簇簇的村落,被飞机、轮船、网络紧密地编织为一体,同样牌号的汽车奔驰在不同大陆的道路上,同样的香水润泽着不同颜色的女性肌肤,电视荧屏上闪现的面孔,总是那几位走红的国际影视或体育明星。到处都是一样的东西,固然容易令人产生某种“万物皆备于我”的虚幻感觉,但同时却又是多么乏味。真希望在习俗、风尚都日趋统一化和标准化的今天,每一片土地,每一个族群,都能够保持自己的某种特性、某种区别性的特征。

  (12)罗密欧手持玫瑰,在朱丽叶的窗下,用歌声呼唤心上人,固然深情款款;而张生、崔莺莺的绣帕题诗,暗诉倾慕,不也有着一份入骨的缠绵?正是这样的独特的地方,让我们确立了自身存在的真实感。即使远离家国,置身于不同肤色、语言的人群中,在某个特定的日子,对于赛龙舟、包粽子、饮雄黄酒的共同记忆和理解,都会让我们相视一笑,莫逆于心。

  (13)上元节、寒食节、灶神节……泛舟在岁月的河流上,每走过一段距离,船都要停靠一个景色别致的码头,加入一次风格独特的庆典。它们让旅人得到暂时的憩息,心中贮满诗意的沉醉,对于天空和大地、山河和岁月、生活和命运,生发出种种感悟。船在水面上轻轻摇荡,人因此而感到从容、安适,感到一种和这条河流、这片土地的牢固的维系……

填空题

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 aminority 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 1.5mears 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 d, omestic factories can churn out a combined 530,000 cars and 30,000 commercial vehicles a year.
