Whether you need to express how long you lived somewhere, how long you
studied astrophysics, or how long you worked as a mime, you'll need to
use 了 (le) to express that time duration.
Basic Usage
Structure
Saying how long you did something for in Chinese can seem tricky, as
there is no preposition as in English. Instead it's all about word
order:
Subj. + Verb + 了 + Duration + Obj.
So 了 (le) is placed after the verb (to indicate that
the action is
completed), followed by the
duration. This is how you talk about the duration of completed actions.
Examples
- 他 学 了 一 年 中文。Tā xué le yī
nián Zhōngwén.He studied Chinese for
a year.
- 我 看 了 一 个 晚上 书。Wǒ kàn le
yī gè wǎnshang shū.I read books
all evening.
- 妈妈 看 了 一 天 电视。Māma kàn le
yī tiān diànshì.Mom watched TV
all day.
- 他 在 Google 做 了 八 年 经理。 Tā zài
Google zuò le bā nián jīnglǐ.He
worked as a manager at Google for eight years.
- 我们 坐 了 十五 个 小时 飞机 去
美国。Wǒmen zuò le shíwǔ gè xiǎoshí
fēijī qù Měiguó.We took a fifteen hour
flight to the United States.
To Express "Definitely Concluded"
Structure
Note that the previous pattern can be used to express the duration of
completed actions which are no longer in progress, although strictly
speaking, it's not entirely clear if the actions are still ongoing or
not. To indicate that the actions are definitely concluded (not
ongoing), a time word may be
inserted into the sentence to indicate that you're talking about an
event in the past:
Subj. + [Time Word] + Verb + 了 + Duration + Obj.
Examples
- 昨天 他 写 了 一 天 作业。Zuótiān tā
xiě le yī tiān zuòyè. He did his
homework all day yesterday.
- 我 刚才 打 了 半 个 小时 电话。 Wǒ
gāngcái dǎ le bàn gè xiǎoshí
diànhuà.I was on the phone for half an
hour.
- 他 今天 喝 了 一 个 晚上 酒。 Tā
jīntiān hē le yī gè wǎnshang
jiǔ.He drank alcohol all night.
- 我 昨天 玩 了 一 个 下午 游戏。Wǒ
zuótiān wán le yī gè xiàwǔ
yóuxì.Yesterday, I played games all
afternoon.
- 上 个 周末 我 和 老公 开 了 三 个 小时 车 回
老家。Shàng gè zhōumò wǒ hé lǎogōng kāi le
sān gè xiǎoshí chē huí
lǎojiā.Last weekend, my husband and I
drove three hours to our hometown.
To indicate that the action is
definitely still in progress, use a
slightly different
pattern.
