Ask German majors to help me analyze the difference between wenn auch and auch wenn, and make it clear that it is better to have an example or something. thank you

In the concession clause proposed by Wen ... auch, when the main clause is postpositioned, the subject of the main clause can be preceded by so, but not when the main clause is prepositioned.

Supplement so.

Sentence pattern:

When he had a drink, he came at once.

______________________ _____

|______________________|

He is not at home, nor is he at home.

_____ __ _____________________

|__________________| |

|________________|

Example:

So is my good friend, so I can't fall at this time.

unterstuertzen，

Although he is my friend, I can't support him in this case.

In order to emphasize, in addition to adding so before the post-main clause, you can also add the related word doctor in the main clause.

When there is still war in this era, our school is great.

Although the time is short, it is beautiful.

When the main clause is postpositioned, if neither so nor doctor is added, the subject of the main clause is at the beginning of the sentence.

He had a friend when he was still wearing a hat.

Busy as he is, he is still learning a foreign language.

Auch wenn's clause also means concession, which can be translated into Chinese as: even if (that is, even if, anyway) ...

Also (still). Note: auch wenn and wenn...auch are different in form and expression:

When it was still there, it was in front of the fireplace.

Although it was cold, he didn't wear a coat.

He is not at home, nor is he at home.

Even if it is cold, he doesn't wear a coat.

Thank you, I hope you can understand. * * * with discussion.
