Laura comes from Canada. She's going to fly to London to see her grandparents, and it is about ten hours away. Laura walks around the airport and has a nice time.
After an hour she wants to go to the toilet(洗手间). She looks for it, but she doesn't find it. "Where is the toilet?" she says. She starts asking other people. Laura says to a man, "Excuse me, sir, could you please tell me where the toilet is?"
The man says, "You mean the restroom, right?" Laura says, "No. I mean the toilet."
"Well, the restroom is over there," he says and walks away.
Laura doesn't understand. She asks a woman, "Excuse me, madam, could you please tell me where the toilet is?"
"The restroom is over there," the lady answers and walks away.
Laura is confused. "What's wrong with them? I need to use the toilet and they tell me to rest! I don't need a restroom. I need the toilet!" After a while, Laura gives up. She feels tired. She thinks she needs to rest.
She walks to the restroom. She is surprised. She now knows the restroom is the name for a public toilet!

1. 从短文第一段“Laura walks around the airport and has a nice time.”可以得知Laura此刻正在机场，还没有飞往伦敦，因此选A。
2. 根据划线单词后文Laura的内心活动，她完全不理解大家的回答，误以为人们都让她去休息，说明她此时处于困惑的状态，因此confused的中文意思是“迷惑的”，选C。
3. 这个故事介绍了不同地区对公共洗手间的不同常用表达，toilet和restroom指代的是同一事物，体现了和语言用词相关的文化差异，文中没有提及机场规则，也没有体现人们不友好，因此选A。
4. 全文的所有情节都围绕Laura寻找洗手间、询问他人toilet的位置展开，核心线索就是找厕所，因此最贴合故事的标题是B选项。
