A問的是世界最高的建筑物
臺北101大樓
目前世界最高的建筑物——臺北101大樓10月8日正式得到世界高樓協會（CTBUH）認證。大樓預計今年年底開張，位于89、91和101層樓的觀景臺也會迎接八方客人，觀光人搭乘全世界最快的電梯，只要39秒就可以到頂樓俯瞰臺北全景。
世界高樓協會將建物高度評定為4個項目，臺北101以508米高度取代了馬來西亞吉隆坡雙子星大樓，囊括了高度項目中3個第一，包括“世界最高建筑物”、“世界最高使用樓層”、“世界最高屋頂高度”，美國芝加哥的席爾斯大樓（SearsTower）僅保有“世界最高天線高度”的最高紀錄。
世界高樓協會指出，世界10大高樓有6棟出現在亞洲，除了臺北101之外，其它五棟分別是上海金茂大廈88樓、香港國際金融中心II期88樓、廣州中信廣場80樓與深圳信興廣場69層，顯見亞洲建筑實力驚人。
據了解，預計將開放的89樓（室內）及91和101樓（室外）3個觀景臺，游客可以在5樓買票，再搭全世界最快的電梯，只要39秒就可以到89樓，再順著樓梯走到91樓觀景。

Ever since they were first put on the market in the early 1990s, gentically mondified (GM， 轉基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr?
Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact
Studies show that the most crown GM croo.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（殺蟲劑）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.
