Suddenly, Alexander 12 and noticed that the driver had detoured from the familiar route.
答案：(A) looked up
looked up（抬頭）表示亞歷山大從書本中抬起頭，注意到司機繞了路；took off（起飛／脫下）、turned in（上交／就寢）、got on（上車）均不符合此處語境。
look up 這個片語，你的印象大概只有「查」（look up a word 查一個字），不太會想到它最字面的意思就是「把頭抬起來往上看」。
答對率四成六，鑑別度只有 28。這一格連高分群考生也常失手，原因就在 look up 的字面義平常很少被單獨拿出來教——越熟悉「查字典」那個用法的人，越會覺得四個選項沒有一個對。回到場景：Alexander 正低頭讀「達文西密碼」讀到第 120 頁，然後 Suddenly, Alexander ______ and noticed that the driver had detoured（突然，Alexander ______，發現司機偏離了路線）。要「發現」路線不對，就得先把埋在書裡的頭抬起來——looked up 就是這個動作。填進去讀成 Suddenly, Alexander looked up and noticed that the driver had detoured。這裡沒有受詞也是一個線索：look up 當「查閱」時後面一定要接查的東西（look it up、look up the word），而這一句空格後面直接就是 and，所以用的是不及物的「抬頭」。
took off（起飛；脫掉）、turned in（繳交；就寢）、got on（上車；相處）三個都是動詞加介副詞的片語，形態吻合，容易被順手選走，但沒有一個接得上「抬頭發現路線不對」這個動作。
look up（抬頭看；查閱）、look up to somebody（敬佩某人）、look down on（看不起）、take off（起飛；脫掉）、turn in（繳交；就寢）、get on with somebody（與某人相處融洽）。
After a long day working in the office, Alexander hailed a taxi to take him home. Squeezing his body into the taxi, he noticed the shiny interior and the smell of brand new leather. After informing the driver of his 11, Alexander resorted to his reading of Dan Brown's intelligent thriller, The Da Vinci Code. Five minutes into the journey, he was on page 120: "…his Mona Lisa is neither male nor female…"
Suddenly, Alexander 12 and noticed that the driver had detoured from the familiar route. To redirect the driver, Alexander tapped him on the shoulder. Out of the blue, the driver screamed, lost control of the car, and almost hit a bus. The cab went up on the footpath and 13 stopped centimeters away from a shop window.
For a second, everything went quiet in the cab. Then the driver said, "Look, mate! Don't ever do that again. You scared the living daylights out of me!" Alexander apologized and said, "I didn't 14 that a little tap would scare you so much." The driver replied, "Sorry, sir. It's not really your 15. Today is my first day as a cab driver. I've been driving a funeral van for the last 25 years."
