今日主題:Urban Food Foraging Looks Fruitful  城市果樹碩果累累

洪欣老師推薦: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 (每句都要聽寫數遍,直到寫出85%以上的字)
3. 最後check文稿,看哪聽不出來,單字沒背過,還是發音不熟。
4. 堅持天天聽,就能每天進步哦。

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:
Foraging for food in urban areas is on the rise. Not dumpster diving. Collecting fruits and herbs.
在城鎮區域採集食物正在興起。不是說翻垃圾桶,而是採集果實和香草。

Throughout cities, forgotten fruit trees still produce, well, produce. For example, there was a peach tree in my former backyard in Somerville, near Boston. And today there are even maps to some of those trees so foragers can take advantage of free produce that otherwise goes largely uneaten—by people, anyway.
在眾多城市中,被遺忘的果樹們仍然開花結果。例如,我以前住在波士頓附近的薩默維爾時,我的花園中就有一棵桃樹。如今,有些地圖甚至標出了這些果樹,方便採集者們可以免費採集果實—反正如果沒人採,也沒有人會吃這些果子。

But after one member of what's called the League of Urban Canners in the Boston area was discovered to have relatively high levels of blood lead, researchers at Wellesley College decided to test urban fruit and herbs. They wanted to see if the fruit posed a threat due to lead or other contaminants in urban soils.
然而,在所謂的城市製罐者聯盟的一位成員檢出血鉛相對水平偏高後,韋爾斯利大學的研究人員決定對城市中的水果與草藥進行檢測。他們想知道城市地區的土壤污染是否使這些食物成為一種威脅。

The League of Urban Canners provided 166 samples of foraged fruit, including apples, peaches, and cherries, and herbs. The scientists dehydrated samples in a manner similar to that of the urban canners, and they compared those specimens to commercially available fruit.
城市製罐者聯盟的成員提供了166種食物樣本,包括了蘋果,桃子,櫻桃與各種香草。研究人員將樣本脫水,以模仿製罐者的食物的狀態。他們將這些樣本與市場上的水果做比較。

Apples did indeed contain lead. But the amount in an average apple was significantly lower than what the EPA considers safe in a day's supply of tap water.
蘋果樣本確實含有鉛。但所有蘋果樣本的平均鉛含量顯著低於EPA所認為每日安全引用水量中的鉛含量。

Next, the team investigated the nutrients in foraged urban fruit. And the picked fruit in general had higher levels of most micronutrients than did store-bought fruit. Calcium and iron were higher in all urban samples, and other nutrients including manganese, zinc, magnesium and potassium were higher in some urban fruits. The study was presented at a recent meeting of the Geological Society of America.
緊接著,他們考察了採集食物中的營養成分。其中採集食物中的微量營養素含量普遍高於市售水果。所有城市水果樣本中,鈣與鐵的含量均較高;部分的城市水果具有更高的鎂,鋅,錳和磷含量。該研究發表在美國地質學會的會議上。

The scientists thus conclude that it's safe and healthy to eat fruit from most urban trees in common spaces. Just make sure that peach does not belong to somebody else before you pick it.
研究人員由此得出,食用城市公共空間中的樹木所結的果實是安全和健康的。不過,採摘之前可要注意,可別採了別人家的果子。
