Asking for things: who you're talking to (B1 Vocabulary)

Use Can you with close friends; use Could you or Would you mind with strangers or for a big favor.

Same favor, different people

WordPronunciationExample
Can youCan you pass me that box, Hiroshi?
Could youExcuse me, could you hold the door for a second?
Would you mindWould you mind checking these figures before I send them?

Would you mind: two shapes

Use Would you mind + -ing when they do it, and Would you mind if I + past or present (if I open) when you do it.

What are the common mistakes?

IncorrectCorrectWhy
"Open the window." to a stranger (sounds like an order)"Could you open the window?" to a stranger (warm and easy)It's about who you're talking to, not about sounding as careful as possible.
"Would you mind if I closed the door?" (when you want them to close it)"Would you mind closing the door?" (the -ing form asks them)if I + past form = you do it; -ing = they do it. Let who does the action pick the shape.
