Other terminology: aspectual particle "了"

When you want to express that an action is completed. Normally 了 should be placed after main verbs or at the end of sentences.
tā
他
HE
măi le
买 了
BUY LE
sān zhāng piào
三 张 票
THREE ZHANG TICKETS

把 酒 拿 来 了
BA WINE TAKE (TOWARDS) LE

2. When should I place the 了 at the end of a sentence, and when should I place it after the main verb of a sentence?
1. If the object of a sentence is a simple one i.e. a noun, which is not attached to a number
and measure word, and not attached to a descriptive clause (的 clause), 了 can be placed at the end of the sentence. In this case the particle 了 has many functions: it may indicate the completed action, or a change of situation, it may also indicate an imminent action.
s. v. o. le
wŏmen chī fàn le
我 们 吃 饭 了.
WE EAT MEAL LE
We have eaten.. [Completed action]
Now we are eating. (We didn't eat before.) [Change of situation]
We are about to eat. (我 们 要 吃 饭 了.)
3. Is it incorrect if I place 了 after the verb in a simple-object sentence?
No, it is not incorrect, but it seems as if the sentence is not yet finished. It may look like the first clause of the verb了...就...construction. For example (Also see pattern 5.),
tā chī le fàn... (jiù qù kàn diànyĭng)
他 吃 了 饭 ... (就 去 看 电 影.)
HE EAT LE MEAL... (JIU GO SEE FILM)
After he finishes the meal...(he'll go to see a film.)
4. Can I place 了 at the end of a sentence that has a complex object?
No. If the object of a sentence is a complicated one, i.e. it is preceded by a number word and measure word, or a descriptive clause, 了 is placed after the main verb of the sentence.
s. v. le num.
