今天雙十節，是不是準備好一起渡過充實的一天啊。
老師與帝國，今兒也都沒放假，和你一起打拼哦!!
今天是假日，選個輕鬆的主題，一起來精聽吧。

 今日主題：Big Apple's Insects Eat Streets Clean
紐約市裡的昆蟲吃光了路上的垃圾

 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。

Rather than cringing at the next beetle or wasp in your way, you might want to thank them—for helping to keep city streets clean.
下次路上見到甲蟲或大黃蜂，也許你不會再躲避，而會想要感謝它們——因為它們幫忙保持城市道路清潔。

Researchers from North Carolina State University working in New York City found that hungry urban arthropods play a significant role in the disposal of trash. For example, in a small section of Manhattan called the Broadway/West Street. corridor, insects consume the equivalent of 60,000 hot dogs a year that would otherwise be lying in the street. And that's assuming the bugs stop chowing down in winter.
來自美國北卡州立大學的研究人員通過在紐約市研究發現，飢餓的城市節肢動物在處理垃圾方面扮演非常重要的角色。比如，在曼哈頓一個名為「百老匯走廊」或者 叫「西街走廊」的小街區，昆蟲每年能消耗的垃圾相當於6萬個熱狗，而若非如此那些垃圾可能會佈滿街頭。這還是假設昆蟲冬天會停止覓食的估計。

To assess how much discarded food bugs got rid of, the researchers placed measured amounts of hot dogs, potato chips and cookies at 21 park sites and 24 street medians. Contrary to their prediction, location played an even bigger role in garbage consumption than biodiversity did—insects gobbled up two to three times more food in the street medians than they did in the parks.
為了評估昆蟲消滅了多少被丟棄的食物，研究人員在21個公園和24條街道中放置了被測量好的巨額熱狗、薯片和餅乾。與他們的預期相反，在垃圾消耗方面，地域比生物多樣性扮演了更加重要的角色——昆蟲們在街道中消耗的食物是它們在公園消耗的2到3倍。

The study appears in the journal Global Change Biology.
該研究發表於《全球變化生物學》雜誌上。

If all that garbage disposal still does not make you an arthropod admirer, then consider this: by competing with larger pests for resources, insects help keep rat populations down. There's some food for thought.
如果這些還不能使你成為一個節肢動物崇拜者，那設想一下：通過與較大的害蟲爭奪資源，昆蟲們還幫我們減少了老鼠的數量。至少也該為口糧著想一下吧。
