correct phrase/punctuation

I really appreciate the culture of Ying Wa, which not only emphasizes academic performance, but also the whole person's development. The learning atmosphere in the school also impressed me very much.

See above. I've added a comma at the end of performance.

Here's an excellent grammar/style manual you may be interested in:

It's called The Elements Of Style by Strunk and White

Thanks, Cliff Hanger.

Cliff Hanger,
Strunk and White's book is not one that an ESL, or even an ENL, should be going to for advice on grammar.

G Pullum, one of the authors of The Cambridge Grammar of the English Language says of it,

"... Strunk and White's toxic little compendium of bad grammatical advice ..."

I really appreciate the culture of Ying Wa, which not only emphasizes academic performance, but also the whole person's development. The learning atmosphere in the school also impressed me very much.

With due respect to Cliff Hanger, I would like to know whether a comma is really necessary after 'performance'. I have always thought that it should be 'not only ... but also'. (no comma).

Please correct me if I'm wrong.

Many thanks in advance.

You're welcome to your opinion and I take it this is a Brit critisizing Strunk and White?

I've found Strunk and White to be useful in stripping away a lot of the excess and getting straight to the point.

I don't see why it couldn't assist someone in learning English. Especially when they are self-motivated.

Mr. Tang, Strunk and White will go into the explanation of why you ought to use commas when putting "which" into a sentence.
