Learn Hardcore Chinese: Wǒmen bùdàn fùxí zhè běn shū, érqiě liànxí shuō hé xiě. - We not only review this book, but also practice speaking and writing.

It links two parallel statements about the same subject: “not only A, but also B.” Here, A is 复习这本书 and B is 练习说和写. Keep the elements parallel (same subject, similar predicate types) and usually both are positive. If A is negated, prefer patterns like 不但不A，反而B.

Where should the subject 我们 go in this pattern?

Typically before 不但: 我们不但A，而且B. You don’t need to repeat it in the second clause. Repeating it (…，而且我们也/还B) is possible for emphasis.

Can I replace 而且 with 也 or 还?

Yes:

我们不但复习这本书，也练习说和写。
我们不但复习这本书，还练习说和写。 Both are natural. 还 sounds slightly more “in addition,” 也 is a neutral “also.”

Can I say 而且还 together?

Yes, very common: 我们不但复习这本书，而且还练习说和写。 The 还 strengthens the additive feel.

Can I drop 而且 entirely?

Yes, if you use 也/还 in the second clause: 我们不但复习这本书，还/也练习说和写。 Don’t write “不但…，练习… ” with nothing to mark “also.”

Is 不但 the only option? What about 不仅/不光/不只?

They’re near-synonyms:

不仅 is common and a bit more formal.
不光/不只 are colloquial. All can form the same pattern: 不仅…而且…, 不只…还…, etc.

Is the pinyin for 不但 pronounced bùdàn or búdàn?

Pronounce it búdàn. Tone sandhi: 不 changes to 2nd tone (bú) before a 4th-tone syllable (dàn).

Why is it 这本书? What does 本 do?

本 (běn) is the standard measure word for bound volumes (books, notebooks). Alternatives:

册 (cè): volume/copy, more formal or for multi-volume sets.
部 (bù): works like novels/films (by work), more formal.

Why use 和 between 说 and 写? Could I use 、, 跟, or 以及/与?

和 is the default coordinator: 说和写.
、 (dùn hào) is a list comma: 说、写 (also fine, especially in writing).
跟 is colloquial; 说跟写 is possible but 和 is safer.
与/以及 are formal and mainly join nouns; 说与写 can sound stiff, and 说以及写 is awkward here.

Is 练习说和写 idiomatic, or should it be 练习说话和写字?

All are possible, with nuances:

练习说和写: broad “speaking and writing.”
练习说话和写字: “speaking (talking) and handwriting.”
More specific and common in language learning: 练习口语和写作 (“spoken language and composition”). Avoid 练说; use 练习说/练口语 instead.

How do I express that these actions are completed?

Use aspect markers and keep both halves parallel:

Completed past: 我们不但复习了这本书，而且（还）练习了口语和写作。
Experiential: 我们不但复习过这本书，而且（还）练习过口语和写作。

Does 而且 always need a comma before it?

Yes, in writing place a comma between the two clauses: …，而且…. It separates the A and B parts of 不但A，而且B.

Can 而且 connect just words, like 复习而且练习?

It connects predicates/clauses or adjectives, not simple nouns. You can say 我们复习，而且练习… (two clauses). Inside a single predicate without 不但, 还 often sounds more natural: 我们复习，还练习….

What’s the difference between 不但我们… and 我们不但…?

我们不但… focuses on our actions (we do A and also B).
不但我们… shifts focus to the subject “we,” implying contrast with others and usually needs a matched second subject: 不但我们复习，他们也复习。

Is the order 说和写 fixed?

No. 写和说 is fine. Common pedagogical sequence is 听说读写 (“listening, speaking, reading, writing”), so 说和写 feels natural, but order isn’t grammatically constrained.

Can I use 并且 instead of 而且?

Yes: 不但…并且… is acceptable, a bit more formal/literary. With 并且, adding 也/还 after it is less common than with 而且, but you’ll still see it in modern usage.
