When I want to borrow a pen from my friend、what should I say?
Choose the right expression out of ①~④.
①Sumimasen pen o kashite kudasai.
②Sumimasen pen o karite kudasai.
③Sumimasen pen o kashitemo iidesuka.
④Sumimasen pen o karitemo iidesuka.
“~te kudasai” expresses request. The speaker asks someone A to do something, so A’s action
comes before “~te kudasai.”
“~temoiidesuka” expresses permission. Thespeaker asks someone whether he/she can do something or not, so the speaker’s action comes before temoiidesuka.
Therefore correct answers are ① and ④
In this case “temoiidesuka” sounds more polite than “tekudasai”
The following sentences are polite expressions to request.
