※ 引述《snark (影燕)》之銘言： : ※ 引述《GOKU123 (GOKU)》之銘言： : : Q:according to the professor, what activities associated with the beginning : : of agriculture may have slowed or prevented the onset of predicted ice age?2ANS : : A. the clearing of trees : : B. the burning of fossil fuels : : C. the domestication of certain animals : : D. the cultivation of certain grains : : 答案是AC : : 但不知道D為什麼錯 : : 內文有說到certain grains 是導致methane 變多的原因應該也屬於溫室氣體吧? : 聽力與閱讀的關鍵之一 : 一開始是練習聽到訊息 : 不過在練習之後會聽到太多的訊息所以要練習提煉重點 : 我們來看看ETS如何騙人呢? : 因為聽力不能先看選項 : 所以要由聽力文章找關鍵 : : 原文相關段落: : : Well, one of the big differences is human activity. People began to raise : : crops and animals for : : food instead of hunting for them. This is the agricultural revolution. And it : : began to happen in the earliest stages about 11 thousand years ago. : : Now, scientists have tended to regard ... the ... uh ... agricultural : : revolution as a beneficiary of the ... uh ... fortuitous2 shift in climate. : : However, some new theories of climate, new theorists of : : climate have proposed that perhaps humanity was having an effect on the : : climate as far back as the beginnings of the agricultural revolution. : : When you grow crops and uh, pasture your animals, one of the things you do is : : you cut down the forests. : 就是這一句有陷阱When這一句提到 grow crops, pasture your animals : 必須 cut down the forests 砍樹 : 但是這一句並沒有說者兩者會造成氣候變化 : 聽力的關鍵就是掌握考點前的關鍵 : 不論是閱讀或聽力 : if 條件句一定是重點 : 種植與放牧如果會造成氣候影響是因為沒有把砍掉的樹種回去 : 換言之答案中光是放牧或種植並非造成氣候影響的原因 : 原因是樹變少了=> CO2 增加 A 我覺得你這邊解釋有點謬誤... agriculture(pasture&growing crops)直接理解為gas增加原因沒問題， P&G必然伴隨的是allowing no trees to grow=>gas增加考題出得錯誤選項設計應該是考 1.能否聽到pasture 2.會不會混淆pasture&domestication，雖然兩個都是牧，但文中是指前者我覺得這是比較specific的闡述，因為如果聽力中是說gorwing animals，那就會概括到游/放牧，這樣選項就不能那樣出了。但今天lecture有往下細說pasture，題目選項中domestication顯然是個蠻適合的陷阱 from my perspective, open to discussion. : If you cut down the forests, when you burn the trees for fuel and don’t replace them with other trees, or when you just : : leave them to rotand don’t allow other trees to grow, : : you end up with a lot more carbon in the form of carbon : : dioxide getting into the atmosphere. : 另一個陷阱是 the burning of fossil fuels : 出現聽力中的 burn 和 fuel : 但是很遺憾的是聽力原文並非 fossil fuels石化燃料 : 所以不能選B : : Um ... another gas associated with the spread of agriculture is methane. : Another 出現時就是另一個原因了 methane 增加 : 由於平行結構你之前應該要知道某種氣體的增加與氣候的關係 : (CO2 造成其增加的原因是砍樹.燒柴.不種回) : : Methane forms in large concentration above wetlands, and as it turns out, : : the cultivation of certain grains creates vast : methane 增加的原因 : cultivation of certain grains 時wetland 增大 : as it turns out 結果發現 : 正是因果句型 : 只是沒有because : 換言之本文的兩個選項A.D其實是考你有沒有聽到這兩種溫室氣體的產生關鍵 : another 是我解題的題眼 : : areas of artificial wetlands, and probably drastically increases the amount : : of methane getting into the atmosphere, over and above what would be there. : : 不好意思不會用顏色把主要句子標出來><" : : 還請大家幫忙^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 67.244.4.119
