I once taught English in Japan, but now study Applied Linguistics in England. For my thesis I need Japanese people, age 16 and older, to try my small English idioms survey. I may offer an Amazon Gift Voucher / アマゾンギフト券 from a prize-draw, if folks allow me to interview them:
Why this survey? Whilst in Japan I felt that my students needed to learn more idioms and fixed-phrases for more natural conversation. However, idioms are very cultural, so I want to understand how Japanese people react to certain types.
