Mandarin Topic-Comment Structure: Fronting the Object

By Michael McGettrick and Wee Khang LinUpdated 12 October 2026

(zhè běn shū wǒ kàn guo): this book, I've read. A Mandarin sentence often opens with what it is about, the topic, and then says something about it, the comment. The object can move to the front with no marker and nothing left behind. It is everyday Mandarin, not a special effect.

Quick check

Three quick questions on what you have just read. The full practice is further down.

Spot the mistake

0/3

Each sentence has one mistake. Tap it.

  1. zhè běn shū wǒ kàn guò tā 。

  2. nà ge diàn yǐng wǒ méi kàn guò tā 。

  3. zhè běn shū wǒ bǎ kàn wán le 。

The whole system on one screen

The colours stay the same all page long:

the topicWhat do the colours mean?
Topic
Subject
The rest

zhè běn shū wǒ kàn guo; nàge rén wǒ rènshi; Běijīng dōngtiān hěn lěng

HanziPinyinEnglish
。Zhè běn shū wǒ kàn guo.This book, I've read
。Nàge rén wǒ rènshi.That person, I know
。Zhōngwén wǒ shuō de bù hǎo.My Chinese isn't good
。Běijīng dōngtiān hěn lěng.Winters in Beijing are cold

Three rules: nothing marks the topic, nothing is left in the gap, and the topic is something you both know. Topic-comment sentences are on the AQA GCSE Chinese specification at Higher tier.

Fronting the object

the topicWhat do the colours mean?

An object you both know can move to the front. The rest of the sentence stays as it was, minus the object:

HanziPinyinEnglish
。Wǒ kàn guo zhè běn shū.I've read this book
。Zhè běn shū wǒ kàn guo.This book, I've read
。Wǒ bù xǐhuan nàge diànyǐng.I don't like that film
。Nàge diànyǐng wǒ bù xǐhuan.That film, I don't like

Both orders are correct and common. The fronted one treats the thing as already on the table, so it is the natural reply when someone has just mentioned it:

  • ？ (Nǐ kàn guo zhè běn shū ma?) - Have you read this book?
  • 。 (Zhè běn shū wǒ kàn guo liǎng biàn.) - This book, I've read twice.

A question word still sits where the answer goes, after the topic: ？ (Zhège zì zěnme xiě?), how do you write this character?

Nothing left behind: no 它 (tā)

the topicWhat do the colours mean?

English says "this book, I've read it". Mandarin leaves the gap after the verb empty, because the topic has already named the thing:

HanziPinyinEnglish
。Zhè běn shū wǒ kàn guo.This book, I've read it
。Nàge diànyǐng wǒ méi kàn guo.That film, I haven't seen it

Putting (tā) back, (zhè běn shū wǒ kàn guo tā), is a typical slip for English speakers.

No marker is needed either. In speech a pause, or a particle such as (a), can follow a long topic: ，。 (Zhè běn shū a, wǒ kàn guo.), this book, yes, I've read it.

Only what you both know

the topicWhat do the colours mean?

A topic is something both speakers can pick out: this book, that person, or a whole kind of thing, such as rice in general. A brand-new "a book" stays after the verb:

HanziPinyinEnglish
。Wǒ kàn guo yì běn shū.I've read a book (news)
。Zhè běn shū wǒ kàn guo.This book, I've read
。Mǐfàn wǒ bú tài xǐhuan.Rice, I'm not keen on

So (yì běn shū wǒ kàn guo) does not work for "I've read a book": nobody knows which book yet.

The topic does not have to be the object

the topicWhat do the colours mean?

The topic can be a place, or a whole of which the comment picks out a part. Then it is not the object of anything, just what the sentence is about:

HanziPinyinEnglish
。Běijīng dōngtiān hěn lěng.Winters in Beijing are cold
。Tā gèzi hěn gāo.He's tall
。Zhège cài wèidào hěn hǎo.This dish tastes good
。Wǒ tóu téng.I've got a headache

English needs a possessive or a preposition: Beijing's winters, his height. Mandarin puts the whole first and lets the part follow.

Two topics can stack, and both orders are natural:

  • 。 (Zhōngwén wǒ shuō de bù hǎo.) - My Chinese isn't good.
  • 。 (Wǒ Zhōngwén shuō de bù hǎo.) - My Chinese isn't good.

Two things side by side

the topicWhat do the colours mean?

Fronting is also how Mandarin sets two things against each other:

HanziPinyinEnglish
，。Mǐfàn wǒ chī, miàntiáo wǒ bù chī.Rice I'll eat; noodles I won't
，。Zhège wǒ yào, nàge wǒ bú yào.I'll take this one, not that one
，。Kāfēi wǒ hē, chá wǒ bù hē.Coffee yes, tea no

Plain order is still correct, ，。 (Wǒ chī mǐfàn, bù chī miàntiáo.), but the fronted version lines the two up.

Topic or 把 (bǎ)?

the topic把 bǎ + the objectWhat do the colours mean?

Both put the object before the verb. A topic usually opens the sentence, before the subject, and needs no result. (bǎ) comes after the subject, and the verb must end in a result:

HanziPinyinEnglish
。Zhè běn shū wǒ kànwán le.This book, I've finished
。Wǒ bǎ zhè běn shū kànwán le.I've finished this book
。Mǐfàn wǒ chī.Rice, I'll eat

The last one has no result, so it cannot become a (bǎ) sentence: (wǒ bǎ mǐfàn chī) is not one. The rest is on the 把 (bǎ) construction.

Mistakes English speakers make

WrongRightWhy
。。the topic named it: no (tā)
。。for "I've read a book": news stays after the verb
。。 (bǎ) needs a result; a topic does not
。。 (bǎ) goes straight before its object

What to do next

  1. Do the drill below.
  2. Answer three questions about things just mentioned, topic first: (zhège cài), (nàge diànyǐng), (Zhōngwén).
  3. Then read the 把 (bǎ) construction again, now that you can tell the two apart.

Frequently asked questions

What is topic-comment structure in Mandarin?
A sentence names what it is about first, the topic, then says something about it, the comment. The topic is often not the subject: in (zhè běn shū wǒ kàn guo), this book, I've read, the topic is the object and the comment is a full clause.
Is correct, or just casual speech?
Fully correct, in speech and in writing. It means the same as (wǒ kàn guo zhè běn shū), I've read this book. The fronted version treats the book as already on the table, so it is the natural reply when someone has just mentioned it.
Do I need to add (tā) after fronting the object?
No. The topic has already named it, so the gap after the verb stays empty: (zhè běn shū wǒ kàn guo). is a typical slip for English speakers.
What is the difference between topic fronting and (bǎ)?
A topic usually opens the sentence, before the subject, with no marker, and the verb needs no result: (mǐfàn wǒ chī), rice I'll eat. (bǎ) comes after the subject and the verb must end in a result: (wǒ bǎ mǐfàn chīwán le), I finished the rice.
Can any object be the topic?
Only one both speakers know, or a whole kind of thing. (zhè běn shū wǒ kàn guo) works. For 'I've read a book', new information, keep plain order: (wǒ kàn guo yì běn shū).
