It just depends on the sentence and what the sentence consists of. As someone has already said, Chinese is a flexible language, I can ask the same question in so many different ways: 你吃午餐了吗？－Did you eat lunch? - Here, the structure is: Subject - Verb - Object 你午餐吃了没有？-Did you eat lunch?- But here, the verb comes *after* the object. Here's another example: In English we generally put the time at the end of the sentence: I'm going to school at 8am. But in Chinese: 我早上八点去上课　 In this sentence the structure is: Subject - time - verb - place. On the bright side, Chinese is nothing like English. In English every sentence has to have a subject. In Chinese you can generally drop the subject (when it is obviously known). For example in English we say "let's ___ together" i.e. 一起吃饭吧，好不好？　－　let's eat together, alright? But In Chinese the sentence syntax is: "together" followed by the verb, (eat). Since the word "together" includes more than one person, it's not necessary to add the subject(but you can if you wanted to). it may seem odd at first, but the more you speak and learn the language, the grammar and syntax will become second nature to you!

I suggest you can learn more chinese sentences,because you know chinese is a flexible language ,several sentences which is different in grammar can express the same ,so I think when you know more chinese sentences ,you maybe find what you doubt is no meaning.

A simple one wo zou le, it means I'm gone wo=subject zou=verb le=complement, it expresses something that is already done.. hope this helps, cheers.

It is subject+verb+compement. For instance, 我 吃 晚餐.
