初中物理教学论文第五单元自然探秘
自然探秘包括从日月星辰、自然地理、矿物资源、物种生态到气候等方方面面的内容，属于通俗科技文体的范畴，主要是一些普及性的科技读物。在英语中这类科技文章统称为科学散文（scientific pro）。通俗科技文体既有正式的书面语特点，又有通俗易懂的修辞风格，使科学与艺术交融，并且尽量使用浅显易懂的语言向读者阐明事理，而不使用术语、符号或公式等。通俗科技文章追求语言的形象性，常常运用比喻、比拟、反问或设问等修辞手法，力求把科学道理讲得明白透彻。
自然探秘资料的翻译跟其他科技资料有着许多共性，要求译者不仅具备扎实的双语语言功底，又要具有良好的自然知识或常识。

Our Summer of Extremes (Excerpt)
By Stefan Rahmstorf
1] This summer has en one of the weather-related extremes in Russia, Pakistan, China, Europe, the Arctic—you name it. But does this have anything to do with global warming, and are human emissions to blame?车辆过户需要什么材料
2] While it cannot be scientifically proven (or disproved, for that matter) that global warming caud any particular extreme event, we can say that global warming very likely makes many kinds of extreme weather both more frequent and more vere.
3] For week, central Russia has been in the grips of its worst-ever heat wave, which has caud probably thousands of fatalities. As a result of drought and heat, more than 500 wildfires have raged out of control, smothering Moscow in smoke and threatening veral nuclear facilities. Russia’s government has banned wheat exports, nding world grain prices soaring.
4] Meanwhile, Pakistan is struggling with unprecedented flooding that has killed more than a thousand people and affected millions more. In China, flash floods have so far killed more than a thousand people and destroyed more than a million homes. On a smaller scale, European countries like Germany, Poland, and the Czech Republic have also suffered rious flooding.
5] Meanwhile, global temperatures in recent months have been at their highest levels in records that go back 130 years. Arctic a-ice cover reached its lowest recorded average level for the month of June ever. In Greenland two huge chunks of ice broke off in July and August.
6] Are the events connected?
7] Looking only at individual extreme events will not reveal their cau, just like watching a few scenes from a movie does not reveal the plot. But, viewed in a broader context, and using the logic of physics, important parts of the plot can be understood.

8] All weather is driven by energy, and the sun ultimately provides this energy. But the biggest change in Earth’s energy budget by far over the past hundred years is due to the accumulation in our atmosphere of greenhou gas, which limit the exit of heat into space. Owing to fossil-fuel emissions, there is now one-third more carbon dioxide in the atmosphere
than at any time in at least a million years, as the latest ice drilling in Antarctica has revealed.
9] The changes in the planet’s energy budget caud by solar variations are at least ten times smaller in comparison. And they go in the wrong direction: in recent years, the sun has been at its dimmest since satellite measurements began in the 1970’s. So, when unprecedented extreme weather events occur, the prime suspect is naturally the biggest atmospheric change that has happened over the past hundred years—one that has been caud by human emissions.
10] The fact that heat waves like the one in Russia become more frequent and extreme in
a warmer world is easy to understand. Extreme rainfall events will also become more frequent and inten in a warmer climate, owing to another simple fact of physics: warm air can hold more moisture. For each degree Celsius of warming, 7% more water is available to rain down from saturated air mass. Drought risk also increas with warming: even where rainfall does not decline, incread evaporation dries out the soils.
11] The carbon-dioxide effect can also change the preferred patterns of atmospheric circulation, which can exacerbate extremes of heat, drought, or rainfall in some regions, while reducing them in others. The problem is that a reduction in tho extremes to which we are already well-adapted provides only modest benefits, whereas the new extremes to which we are not adapted can be devastating, as recent events in Pakistan show.

极端天气肆虐的夏天（节选）
斯特凡.拉已经禁止小麦出口，导致姆斯多夫
1】在俄罗斯、巴基斯坦、中国、欧洲和北极，凡是能想到的地方，这个夏天极端天气都在肆虐。但这与全球气候变暖有关吗？人类的碳排放是肇事之因吗？

2】尽管在科学上还无法证明（或否定）是全球变暖导致了某些特定的极端天气，我们还是可以说全球变暖很可能使多种极端天气发生得更频繁、更恶劣。
3】几周以来，俄罗斯中部地区深陷于历史上最严重的热浪之中，由此而造成的死亡人数可能高达数千。由于干旱和高温，500余处野火迅速蔓延，失去控制，把莫斯科笼罩在令人窒息的烟雾中，并威胁到几处核设施。俄政府已经禁止小麦出口，导致全球谷物价格飙升。
