If you take a 29 to a different time zone, caffeine can help you overcome jet lag.
答案：(B) flight
語意「如果你搭『飛機』前往不同時區」，flight（班機）符合這種跨時區旅行的具體交通工具語境；break（休息）、leave（離開）、travel（旅行，太籠統不夠具體）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。
四個選項擺進 take a ___ 都唸得通，而 travel（旅行）在講跨時區的句子裡看起來最貼切。這一格的證據在下一句那個專有的詞。
四個選項都是名詞，可見這一格考的是搭配與語意。先看句型：If you take a ___ to a different time zone（如果你搭……去到不同的時區）。再往後讀半句，硬證據就出現了：caffeine can help you overcome jet lag（咖啡因可以幫你克服時差）。jet 就是噴射機——jet lag 這個字本身就指明了交通工具是飛機，所以填 flight，take a flight 就是「搭飛機」。下一句 Most hotels have coffee and tea service in the room for this very reason（正因如此，多數旅館房間裡都備有咖啡與茶）也印證這是長途飛行後的情境。
travel（旅行）：take a travel 不是通行的說法（要說 take a trip 或 go on a trip）；而且 travel 太籠統，配不上 jet lag 這個明確的線索。break（休息）：take a break 是「休息一下」，但休息不會讓人跨到不同時區。leave（假期）：take leave 是「請假」，不加冠詞 a，形態就不合；語意上請假也不等於移動到別的時區。
take a flight（搭飛機）、take a trip（去旅行）、take a break（休息一下）、take leave（請假）、jet lag（時差）、a time zone（時區）。

Caffeine is also the main ingredient in many "diet pills." It boosts metabolism, thereby 28 the body to burn more calories. If you take a 29 to a different time zone, caffeine can help you overcome jet lag. Most hotels have coffee and tea service in the room for this very reason.
