Cave Graffiti 在托福超愛考的哦~~ 中秋快樂哦~~

今日主題:Cave Graffiti Agrees with Site's Drought Evidence
塗鴉竟和乾旱有關係!!

托福聽力最好的課外教材:60-Second Science
康康精選托福會考的主題,堅持每天精聽一定會進步的哦!!

建議方法:
1. 先聽兩三遍(不看文稿)
2. 再一句一句聽寫
3. 最後check文稿,看哪聽不出來,是單字沒背過,還是單字發音不熟。
4. 堅持天天聽,就能每天進步哦。

MP3音檔:喜歡的同學,幫忙推或按讚哦~~

只有音檔怎夠,聽不懂地方,不用怕,康康幫你準備好中英文稿了:

中英文稿:

Historical instances of dramatic societal upheaval have been attributed to changes in climate. Now a cave in China has been shown to contain both physical evidence for specific periods of drought and written records of the hardships—in the form of graffiti—by people suffering from those droughts. The findings are in the journal Scientific Reports.
氣候變化會導致劇烈的歷史動盪。在中國境內的一個山洞已被證實含有可證明某段歷史時期發生過旱災的自然記錄,同時還含有記錄當時人們苦難生活的文字記載——以塗鴉的形式——由當時遭受苦難的人們記錄的。該研究成果發表在《科學報告》雜誌上。

During the past 500 years, people made regular pilgrimages to the Dayu Cave in the Qinling Mountains of central China. During seven of the visits—the oldest one going back to the year 1520—pilgrims left messages on the cave walls related to droughts.
在過去500年裡,人們經常前往中國中部秦嶺山脈的大禹洞穴進行朝拜。在有文字記載的七次記錄中——最久遠的一次可以追溯到1520年——朝拜者在洞穴的牆壁山記錄了關於當時旱災的信息。

Researchers were able to link those graffiti, which contain dates, to physical evidence of the water shortages. For example, lack of water caused changes in ratios of stable isotopes in specific layers of cave formations, such as stalagmites. The site has thus provided the first known case of historical and geological records existing in the same cave.
研究人員可以將那些包含日期的塗鴉和旱災的實體證據關聯起來。例如,水資源匱乏引起了洞穴在形成過程中其特定的岩層穩定性同位素比例發生變化,例如石筍結構。這是人類首次在同一洞穴中發現自然歷史記錄和地理記錄。

Cambridge University Earth scientist Sebastian Breitenbach is a co-author of the study. He says that records found in caves and lakes in the last decade reveal possible links between climate change and the downfall of several Chinese dynasties, including the Tang and Ming. He also notes, 「Things in the world are different from when these cave inscriptions were written, but we're still vulnerable to these events—especially in the developing world.」
劍橋大學的地球科學家塞巴斯蒂安‧佈雷唐巴克四該研究的共同作者。他說,最近十年在洞穴和湖泊發現的這些記錄揭示了中國數個朝代的衰敗可能與氣候變化有關 係,例如唐朝和明朝。他還指出,現在發生的事情和當時山洞碑文記載的不同,但是,我們仍易受到這些事件的影響——尤其是在發展中國家。
