Wǒmen búdàn fùxí zhè běn shū, érqiě liànxí shuō hé xiě.

不但……而且…… means not only... but also...

In this sentence:

• 我们不但复习这本书 = We not only review this book
• 而且练习说和写 = but also practice speaking and writing

This pattern links two parallel ideas. What comes after 不但 and what comes after 而且 should match reasonably well in structure.

A very literal breakdown is:

• 我们 = we
• 不但 = not only
• 复习这本书 = review this book
• 而且 = but also / moreover
• 练习说和写 = practice speaking and writing

This is because of tone sandhi, a pronunciation change rule.

Normally:

• 不 is fourth tone: bù

But when 不 comes before another fourth-tone syllable, it changes to second tone:

• 不 + 但(dàn, 4th tone) → búdàn

So the written character stays 不, but the pronunciation changes.

Other common examples:

• 不是 → búshì
• 不要 → búyào
• 不能 is usually still bùnéng, because néng is second tone, so no change

本 is the measure word for books.

In Chinese, when you say this, that, one, two, etc. with a noun, you usually need a measure word between the number/demonstrative and the noun.

So:

• 这本书 = this book
• 那本书 = that book
• 一本书 = one book

Structure:

• 这 = this
• 本 = measure word for bound books
• 书 = book

Saying 这书 is generally not the normal standard pattern here.

They are related, but not the same.

• 复习 = to review
  • usually means going over material you have already learned
• 练习 = to practice
  • usually means doing exercises or practicing a skill

In this sentence:

• 复习这本书 = review this book
• 练习说和写 = practice speaking and writing

So the sentence contrasts two kinds of study activity:

1. reviewing content
2. practicing skills

Because 练习 is the main verb here, and 说和写 are what is being practiced.

So:

• 练习说和写 = practice speaking and writing

You can think of 说 and 写 here almost like speaking and writing in English.

This is very common in Chinese: a verb such as 练习 can be followed by another verb or verb phrase to show what activity is practiced.

Examples:

• 练习说中文 = practice speaking Chinese
• 练习写汉字 = practice writing Chinese characters

In Chinese, verbs can often function more flexibly than in English.

So 说 literally means to speak, and 写 means to write, but after 练习, they can naturally mean:

• speaking
• writing

So 练习说和写 is perfectly natural for practice speaking and writing.

Chinese does not always need a special -ing form like English does.

Yes. 和 often means and, and it can connect not only nouns but also verbs or verb phrases when they are parallel.

Here:

• 说和写 = speaking and writing / to speak and to write

So 和 is linking two coordinated actions.

You may also sometimes see 说、写 with the list punctuation mark 、 in writing, but 和 is completely normal here.

In this pattern, 而且 is the standard partner for 不但.

So:

• 不但……而且…… = not only... but also...

It makes the sentence sound complete and balanced.

In everyday speech, native speakers may sometimes use related patterns such as:

• 不但……还……
• 不但……也……

But 不但……而且…… is one of the most standard textbook forms.

The comma marks the division between the two halves of the 不但……而且…… structure.

So the sentence is grouped like this:

• 我们不但复习这本书，
• 而且练习说和写。

This helps the reader hear the contrast/addition clearly: not only X, but also Y.

In Chinese writing, punctuation is important for showing structure, especially in longer sentences.

It depends on context.

Chinese often omits subjects when they are already understood. So if the conversation already makes it clear who is doing the action, 我们 could be left out.

But in a full standalone sentence, including 我们 is natural and clear.

So:

• 我们不但复习这本书，而且练习说和写。 = clear, complete sentence
• 不但复习这本书，而且练习说和写。 = possible if the subject is already obvious from context

The object is left general or understood from context.

In English, practice speaking and writing also does not have to specify exactly speaking what or writing what. Chinese works similarly here.

So:

• 说 = speak
• 写 = write

The sentence focuses on the skills themselves, not the exact content.

If you wanted to be more specific, you could say something like:

• 练习说中文和写汉字 = practice speaking Chinese and writing Chinese characters

Yes, that is a good way to think about it.

The subject is:

• 我们 = we

Then there are two coordinated predicate parts:

1. 不但复习这本书
2. 而且练习说和写

So the overall structure is:

• Subject + not only do A, but also do B

This is very common in Chinese and works much like English.

Yes, if the meaning changes appropriately.

听说读写 means the four language skills:

• 听 = listening
• 说 = speaking
• 读 = reading
• 写 = writing

So if you wanted to say we not only review this book, but also practice listening, speaking, reading, and writing, you could use a phrase like that.

But in the original sentence, only speaking and writing are mentioned, so 说和写 is the correct match.

Literally, it means this book, referring to a specific book.

However, in context, 复习这本书 can naturally imply reviewing the material or lessons in that book, not just physically looking at the object.

So depending on context, it may mean:

• review this book
• review the material in this book

That kind of slight extension of meaning is very normal in Chinese, just as it is in English.
