The main characteristic of Chinese sentence is that it lacks of morphological changes in person, tense, gender, number, and case in the strict sense. The sentence order is very important to convey different grammatical meanings.
The sentences with an adjective predicate:
Adjective in Chinese can function directly as predicates. This kind of sentence can be modified by adverbs such as “很”“也”“都” and etc. And the negation form is to put “不” before adjective that functions as the predicate.
Subject + Predicate
我忙。（Wǒ máng.）I`m busy.
我很忙。（Wǒ hěn máng.）I`m very busy.
我不忙。（Wǒ bù máng.）I`m not busy.
我们都很忙。（Wǒmen dōu hěn máng.）We are all very busy.
The sentences with a verbal predicate:
The main part of the predicate in a sentence with a verbal predicate is a verb. The object usually follows the verb. The negative form is formed by putting “不” or “没” before the verb.
Subject + (Adv. ) + Verb + (Object)
我爱你。（Wǒ ài nǐ.）I love you.
我们都喜欢汉语。（Wǒmen dōu xǐhuān hànyǔ.）We all like Chinese language.
你在哪儿？（Nǐ zài nǎr?）Where are you?
我不知道。（Wǒ bù zhīdào.）I don`t know.
