Generally speaking, BA constructions indicate ‘intentional manipulation’ as most of the above examples show. Occasionally, however, a BA construction may also indicate ‘unintentional intervention’ or the result of it. To emphasize the accidental nature of the event, GEI may be optionally introduced before the main verb. For example:
mèi mèi bǎ qún zǐ （gěi ）nòng zāng le 。
My younger sister dirtied her skirt.
dì dì méi （yǒu ）bǎ diàn nǎo （gěi ）gǎo huài 。
My younger brother did not break the computer.
搞(GAO) and 弄(NONG), both meaning ‘handle’, are often used in association with complements indicating undesirable results.
We have seen that the object of BA normally has definite reference, but, if the speaker is making a factual or argumentative statement rather than recounting an incident, the object can refer to something generic or categorial, that is, to a category of things rather than the individual thing itself. For example,
tā bǎ xī hóng shì kàn zuò shuǐ guǒ 。
She regards tomatoes as fruit.
bié bǎ péng yǒu dāng chéng dí rén 。
Don’t look upon your friends as enemies.
