Subject-predicate sentences
I ask you for help about Grammar in Chinese.

Quote: In Chinese there is such a kind of sentence in with the predicate is a subject-predicate phrase.
Examples:
1. 我身体不太好。我 is subject of this sentence, 身体不太好 - predicate.
2. 明天天气很好。明天 is subject, 天气很好 - predicate.

Why 身体 and 天气 are a part of predicate? I thought that 身体 is subject and 我 definitive (天气 - subject, 明天 - definitive).

Subject-predicate sentences
I ask you for help about Grammar in Chinese.

Quote: In Chinese there is such a kind of sentence in with the predicate is a subject-predicate phrase.
Examples:
1. 我身体不太好。 我 is subject of this sentence, 身体不太好 - predicate.
2. 明天天气很好。明天 is subject, 天气很好 - predicate.

Why 身体 and 天气 are a part of predicate? I thought that 身体 is subject and 我 definitive (天气 - subject, 明天 - definitive).

Answer

1. 我身体不太好。我isn't the subject. 我（的）身体 is the  subject of this sentence. 的，means of, is omitted here.
2. 明天天气很好。This sentence is the same. 明天（的）天气 is the subject.

Answer

when you translate  我身体不太好 into English, "My body is not well".  "body" is the subject.  "my" just clarifies whose body.

明天天气很好 tomorrow's weather is good.  So the subject again is weather not tomorrow.  Modern Chinese has the same grammatical structure as English from the SVO point of view.

Answer

你现在的这个情况很正常，我们学语言也是这样，尤其是语法，我建议你先不要这么费劲学语法，先慢慢学进去基本的日常用语，然后慢慢会提升的，那个时候你不会问这个问题。其实中文的语法很好学，不是其他语言一样变位动词，名词，形容词，数字 。所以你先慢慢进去中文，
