Subject-Predicate Phrases

A subject-predicate(S-P) phrase is one particular in which the constituents are combined in the S-P relations. In mandarin language, the S-P phrase is widely employed. In a subject-predicate sentence the subject is first and the predicate is second. The subject may be the object of the statement and it is often a noun or pronoun. The predicate tends to make a statement in regards to the subject and is generally a verb or adjective. No function words are utilized between the subject and predicate. The majority of the words you mentioned contain it. For instance:
 
头发长 (头发is the subject and the predicate.)
他书写 ( is the subject and 书写 the predicate.)
 
The order of the two constituents is fixed together with the subject preceding the predicate.
The first constituent of a S-P phrase is generally a noun or pronoun serving as a subject or the topic, as well as the second one, typically a verb or an adjective, would be the predicate describing the subject. For instance:
我闻到…[I smelt…](The pronoun is the subject and 闻到, a verb)
No function word whatsoever is used between the two constituents.
The second constituent is normally stressed in pronunciation.
 
In Mandarin Chinese, S-P phrase is used as the subject, predicate, object, attributive, adverbial adjunct and complement of degree.
他这样做不对。[He did the wrong thing.](As the subject)
他手指破了。[His finger is injured.](As the predicate)
我希望你成功。[I wish you success.](As the object)
您提的意见很正确。[The opinion you put forward is quite correct.](As an attributive)
他说得大家全笑了。[What he said makes us laugh.](As a complement of degree)
 
At last, I also want to mention the points that you should remember.
The order of the two constituents in an S-P phrase cannot be reversed, for the reversion of order will bring about a change both in structure an in meaning.
The two constituents of an S-P phrase have to match; otherwise, S-P phrase won’t make any sense.
An S-P phrase can function as subject, object or attributive without being introduced by a pronoun.
