1 . But if I'm talking to someone who isn't very close to me, I must make my request longer—and I must make it a question, not a demand, e.g., “Could you open the window, please?”(英译汉）

2 . If I'm talking to a close friend, I can use short requests, like “Open the window”—our relationship is close and we're equals, so I only need a few words to bridge the gap between us.(英译汉）

3 . This morning, I was worried that no one would talk to me. （英译汉）
