Fist one, one of the main features of Chinese grammar is that the words used in a sentence show no morphological change for meaning,mood,aspect,gender,register, or tense. No matter whether the Chinese words are in a dictionary or in a sentence, and regardless of what position they occupy within a sentence, they are using the same way to read and write.
Secondly, there are a large number of important function words in Chinese; through The grammatical and grammatical meanings of sentences are mainly manifesting in this point.. The role of function words in Chinese is roughly equivalent to that of morphological changes in Indo-European languages.
Essentially, rather than changing the form of the word itself, Chinese adds independent words to the sentence. For example, in the sentence “Zuotian shui lai le? (昨天谁来了?) Who came yesterday?” “le了” is used to indicate that the action “come” has been completed, but the form of “lai来” is not changed. In English “come” should be changed to “came” or perhaps “have come.”
And the last, Chinese sentences convey much of their meaning through word order, as in English. Other languages indicate subjects and objects with cases or other grammatical markers. In both Chinese and English, however, it is the position of words in a sentence that shows the subject (or agents) and object (or patient) of the action.
