"I 33 you at the airport.
答案：(B) saw
簡單過去式 saw，陌生人說「我在機場看到你」，直述一個明確過去時間點發生的動作；have seen（現在完成式，不符合這種具體過去場景）、had seen（過去完成式，時態不合，沒有更早的參照點）、was seeing（過去進行式，不符合這種瞬間動作的簡單陳述）都不如 saw 自然。
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 see 的形態變化，你會先想「這句話在講什麼時候的事」，然後在過去式與現在完成式之間猶豫——因為「我見過你」聽起來很像現在完成式的經驗用法。
四個選項都是同一個動詞 see 的時態變化，可見這一格考的是時態。說話的是那個陌生人：I ___ you at the airport. I work there at the customs.（我在機場……你。我在那裡的海關工作。）先看時間點：「我」是剛搭飛機抵達的，機場那一次是一個已經結束、時間也很明確的過去事件，直述這種事用過去簡單式就好，填 saw。
have seen：現在完成式講的是從過去延續到現在的狀態，或不指明時間的經驗，不與一個明確的過去場景並用。had seen：過去完成式需要另一個更晚的過去時間點當基準，先發生的那一件才用它，而本句只有一個過去時間點。was seeing：過去進行式。這裡還有一個更根本的問題——see 表示「看見」時是狀態動詞，講的是眼睛接收到的結果，不是一段可以持續進行的動作，所以一般不用進行式。（see 真的用進行式時意思會變，例如 I am seeing a doctor. 我正在看醫生；I am seeing someone. 我和某人在交往。）
see sb at the airport（在機場看到某人）、work at the customs（在海關工作）、How are you enjoying …?（你覺得……如何）、be seeing sb（與某人交往中）、a customs officer（海關人員）、a stranger（陌生人）。
It was my first day in this beautiful tropical city. 31 I was walking to the beach, a stranger came up to me and tried to shake my hand. "Don't you remember me, my friend?" he said. But I couldn't 32 his face at all. I didn't know a soul in the city. I had just arrived by plane and still had jetlag. "I 33 you at the airport. I work there at the customs. How are you enjoying our beautiful city?" I couldn't remember him but I was too 34 to tell him. He was so friendly.
35 he offered to take me to his uncle's seafood restaurant, just by the beach. I thanked him 36 but he insisted that we should go there for dinner. "You'll love the seafood there," he 37 me. "And it will be a dinner to remember."
So we went to the restaurant and sat by a window 38 the bay. The dinner was great indeed, but the coffee they served was quite different. In fact, it tasted very strange...
Anyway, it was not 39 10 o'clock the next morning that I finally woke up. But I had no idea where I was. All my money was 40 and my "friend" had even taken my watch and my shoes!
