Manner adverbials describe the manner in which an action is conducted. They are realized most commonly by adverbs (adjectives (+ de)) and less commonly by NP, prepositional phrases or clauses. The following are some examples:
Tā xiàng fāfēngde lǎohǔ sì de páoxiàozhe.
(He was venting his rage like a desperate tiger.)
Tā jíkuài de wǎng wài zǒu.
(She quickly walked towards the outside.)
Fùnǚmen chuāndài de zhěngzhěngqíqí de qù cānjiā liánhuānhuì.
(The women, all dressed up, went to join the get-together.)
Tāmen páichéng dān háng zǒuzhe.
(They were walking in a single line.)
Tā chǎngkāi xiōnghuáijìnqíng de hūxī zìyóu de kōngqì.
(Opening wide his heart, he inhaled the air of freedom as much as he liked.)
Adverbials of manner in the above sentences are realized by adverbs (1b, e), or by VPs (1a, c, d), they all describe states that start with and accompany the actions performed by the subject referents.
