Five hours into its 28 , the vessel strayed from its shipping lane.
答案：(D) journey
語意「航行五小時後，這艘船偏離了航道」，journey（航程）符合；ocean（海洋）、setting（背景）、vacation（度假）都不合。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個選項都是名詞，而這一段講的是船在海上，ocean（海洋）看起來很有畫面。但這一格要填的是一段「歷程」，不是一個地方。
四個選項都是名詞，可見這一格考的是語意。先看空格前面：Five hours into its ___ ——into 在這裡是「進入……之中」，配上時間就是「在……進行了五小時的時候」。能被「進行五小時」的必須是一段有起點、有過程的事，而前一句說 A cargo ship, Shen Neng 1, left Australia for China（一艘貨輪神能一號從澳洲開往中國），那正是一段航程，填 journey。整句是「啟航五小時後，這艘船偏離了航道」。
ocean（海洋）：是地點不是歷程，five hours into its ocean 不成說法。vacation（假期）：貨輪運煤不是去度假。setting（背景、環境）：講的是場景，同樣不是一段可以計時的過程。
five hours into one’s journey（航行、旅程五小時後）、leave A for B（從 A 出發前往 B）、a cargo ship（貨輪）、stray from（偏離）、a shipping lane（航道）、plow through（一路輾過、衝撞而過）。
