No comment, very instructive
Thanks for your help.
I highly appreciate it.
You are super teacher as me.
I really have as much experience as you.
I have a proven skills and technical methods.
Teachers, I'd like to know clearly about No.6 of Exercise-2. It stated, " I slept on the train, using my jacket ---- a pillow". I confused to fill "as" or "like" in the blank. Is the jacket a similar use like a pillow or the same use as a pillow? Pls.
In this sentence, the jacket is fulfilling the function of a pillow, so 'as' is the correct answer.
All the best,
