4. 语法小结 （yǔ fǎ xiǎo jié）Grammar Notes
The particle 了 (le) has a [|lot of uses]. One of the most common is to express the completion of an action. This is called [|aspect], which is not the same as tense. Tense is about //when an action happens// - past, present or future. Aspect is about //whether the action is complete// in whatever time frame we're talking about.

The Basic Pattern
To indicate completeness with 了, the structure is: Subject + Verb + 了 + Object Notice that 了 goes directly after the verb. This 了 is called **verb 了**.

Example Sentences
Some basic examples:
 * 我 吃 //了// 两 个 苹果. I ate two apples.
 * 我 看 //了// 一 本 书. I read a book.
 * 我 看见 //了// UFO. I saw a UFO.
 * 我 学//了// 两 年 中文. I studied two years of Chinese.
 * 他 去 //了// 台湾. He went to Taiwan.
