【結(jié)構(gòu)簡析】 由"and"連接的兩個句子，這些動作是自然而然發(fā)生的。你到了一個地方，先是 "pick up" 摘葉子然后就是"compare"這些葉子。其他成分是用來說明這些葉子的修飾成分。
【參考譯文】 去一個特定的區(qū)域，摘下該地區(qū)樹上所有不同種類的樹葉，然后比較該地區(qū)齒狀形樹葉物種的數(shù)量。

【結(jié)構(gòu)簡析】這個長句子要表達(dá)的意思非常的簡單，就是你愈往上走，就愈感覺到冷。
【參考譯文】如果今天你就坐在熱氣球里，在這兒你會直線上升飄到大氣層中，可以預(yù)見溫度會不斷的下降。事實(shí)也證明，在大氣中每上升一英里，就下降華氏20度左右。
