名词谓语句
名词谓语句 — noun predicate (no 是)
Pattern
+
a time, an age, a price or a date
( ) can be left out · other words may come before, between and after
How it works
For age, clock time, dates, prices, and the weather, a noun phrase can serve as the predicate directly, with no 是. It is common in casual speech; the negative form does add 不是.
Examples
今天星期一。
Jīntiān xīngqīyī.
Today is Monday.
他二十岁。
Tā èrshí suì.
He is twenty years old.
现在三点半。
Xiànzài sān diǎn bàn.
