I couldn’t remember him but I was too 34 to tell him.
答案：(D) embarrassed
語意「我太尷尬了，不好意思告訴他（我不記得他）」，embarrassed（尷尬的）符合這種社交場景的心理狀態；exhausted（筋疲力竭的）、interested（感興趣的）、frightened（害怕的）都不符合這個「不好意思承認不記得對方」的語境。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
前面才剛講過 I still had jetlag（我還在時差裡），所以 exhausted（筋疲力竭）看起來很有根據——文章明明說了他很累。這正是這一格設計得最巧的地方：它給你一個真的存在的線索，但那個線索指向錯的方向。
四個選項都是描述情緒或狀態的形容詞，可見這一格考的是語意，而關鍵在 too ... to 這個句型。too ... to 的意思是「太……以致於不能」，所以空格填的那個狀態必須是「說不出口」的原因。整句是 I couldn’t remember him but I was too ___ to tell him.（我想不起他是誰，但我太……而說不出口。）想不起對方是誰、卻不好意思承認——這是社交場合的尷尬，填 embarrassed。再回頭看那個陷阱：jetlag 確實讓他很累，但「累」不會讓人說不出「我不記得你了」這句話，兩者之間沒有因果。線索存在不代表它管這一格，填之前一定要用 too ... to 的因果關係驗算一次。
exhausted（筋疲力竭的）：見上，前文雖然埋了伏筆，但因果接不上。frightened（害怕的）：對方一路都很友善，還主動要請客，沒有讓人害怕的成分。interested（感興趣的）：太有興趣不會導致說不出口，語意完全反了。
be too … to V（太……以致於不能）、be embarrassed to V（不好意思做……）、feel embarrassed about（為……感到尷尬）、be exhausted（筋疲力竭）、tell sb the truth（對某人說實話）、so friendly（如此友善）。
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!
