Foreign Language Correction

1. I don’t see any reason why “& TESOL” should be deleted.
It is only the information that the host would like to provide to the readers.
2. “have been learning - recently” is present perfect continuous tense; while “am studying- these days” is present continuous tense. I don’t see why it can’t be present perfect continuous. How can you be sure that the host is still studying instead?
3. I study Japanese to an N4 level on my own =/= I study Japanese on my own but I am still N4 level.
The amendment twisted the original meaning. I think what that host said was:
I study Japanese on my own and managed to reach N4 level.
=> I managed to reach N4 level by studying Japanese on my own.
4.like to do a language exchange=/= are interested in practising English with me.
The amendment twisted the original meaning.
Exchange languages involved both languages. Practising English involved only English.
(practising(UK): practicing(US): I tend to use UK English)

“to do a language exchange” is not grammatically incorrect. However,
“to exchange languages” is much better. Since “do” have an emphasizing effect.

In short the original is much better than the above amendments.

Holing a TEFL/TESOL doesn't mean that you are a native English speaker. You had better delete English from your mother tongue list. I have never seen TEFL/TESOL qualified people who don't understand the meaning of mother tongue :D Besides, fake English native speakers are usually scammers whose purpose is finding dupes, I believe you are not such people.

1. Native speakers say like ゛such as TEFL, TESOL, and business English“, you put “and (&) “at an inproper place. Also usually just one or two things are followed by “such as“, so omitting “TESOL“ is still reasonable.

2. Native speakers don't use “recently“ and “have been learning“ together, if you focus on “recently“, it would be “I have started applied linguistic course“ or something like that. If you want “l have been leaning “, your leaning involves not only now but also past , so adding “recently “ doesn't make sense.

3. Suggested sentence by the first one is closer to her Japanese message . If you say like the second one suggested, it would be slightly different.

4. I am sure suggesting “practicing/practising “ instarted of “exchanging“ is a sarcasm, you still need to practice/prdctise English to inprove it, not ready to help the other.

In short, pretending to be a native speaker and beina a troll are ridiculous.

I am sorry if my reply offence anyone, I am not intend to help any suspected scammer.
I just genuinely think that the amendments are ill-advices. English is English. I aimed at improving English only. Of course I am no expert.
