　　全球變暖

　　As is subtly revealed in the cartoons above, global warming is a real threat to our world. In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.

　　The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world. To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress. China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy. With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising. In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms. Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.

　　Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world. Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.

　　正如上述漫畫生動所示，全球變暖是當(dāng)今世界的真正威脅。在圖一中，由于全球變暖，極地冰川正在加劇融化。在圖二中，一只無家可歸的北極熊呆在一塊孤立的大冰塊上。

　　這些漫畫的目的是告訴我們：全球氣候變暖對全世界的人們來說是迫在眉睫的威脅。首先，全球氣候變暖會導(dǎo)致海平面的上升。由于氣候變暖，中國大多數(shù)沿海地區(qū)都將隨著海平面的上升逐漸消失，嚴重危害了國家的社會和經(jīng)濟發(fā)展。中國漫長的海岸線遍布著中國70%的大城市，人口數(shù)量占到全國總?cè)丝诘囊话胍陨希刂浦鴩医?jīng)濟的將近60%。這些城市的社會、經(jīng)濟和文化發(fā)展程度相對先進，如果海平面繼續(xù)保持上升的話，那么對于中國的內(nèi)陸城市來說將會承受巨大的損失。其次，全球氣候變暖加大了出現(xiàn)極端天氣的可能性并加重其強烈程度，例如颶風(fēng)、雪災(zāi)。在最近30年里，颶風(fēng)和臺風(fēng)持續(xù)的時間越來越長，強度也越來越大。這是與全球氣候變暖所帶來的海平面溫度上升緊密聯(lián)系的。

　　考慮到全球氣候變暖帶來的這些毀滅性影響，我們可以得出結(jié)論：全球氣候變暖是全球的一大威脅。面臨著日益增長的威脅，我們應(yīng)該大規(guī)模采取更加積極、科學(xué)的預(yù)防性措施來促使其向更好的方向發(fā)展。
