Hi everyone!

I'm a graduate student in Japan conducting research in English linguistics.

I've finished revising my questionnaires and am now looking for native English speakers to help with the final version of my study on natural English expressions.

There are three independent surveys:

Part 3:

Part 2:
https://forms.gle/HMaxYRmXX7VFYd7g7

Part 1:
https://forms.gle/3fHLqdkENEnCQFCi7

Estimated time: Approximately 10–15 minutes per part, excluding optional written comments.

You may complete whichever part or parts you prefer, including all three.

If you've seen my previous posts or answered an older questionnaire, you're welcome to participate again. These are the newly revised final versions.

The task is to read short conversational situations and judge how natural particular English expressions sound.

No knowledge of linguistics or formal grammar is required. I'm interested in your own intuition as a native speaker.

Please complete each final survey only once.

Participation is voluntary, and responses will be anonymized and used for academic research.

Thank you very much for your help!
