Sentence agreement

[Ichirocanada]

hi, I've asked quite a few people about the status of the word "change" in the sentence " i hated to see it change". Some said it's infinitive and others noun; however, either one makes sense to me. If "change" is infintive, what is "to see" then? If it's noun, what is "it" then? Also, what is the word "started"in “ most people are fast to stop you before you get started but hesistant to get in the way if you are moving”？　ｉｓ　ｉｔ　ｔｈｅ　ｓａｍｅ
ａｓ　”ｃｈａｎｇｅ”　ｉｎ　ｔｈｅ　ｆｉｒｓｔ　ｓｅｎｔｅｎｃｅ？　Can someone please help me with this？ Also, do tenses in the same paragraph and sentence need to agree with each other? From my understanding, tenses have to agree with each in an essay/article; however, I, sometimes, come across several different tenses in the same paragraph and sentence. For example, tenses in this paragraph “it was Feb 16, 2006, and he was now a mogul skiing gold medalist at the Turin Winter Olympics. Unlike other full-time athletes, he will never have to return to a dead-end job after his moment of glory” don’t match with each other

In addition, tenses don’t agree with each other too in this sentence “Using dehydration techniques I now teach to elite powerlifters, I lost 28 pounds in 18 hours, weighed in at 165 pounds, and then hyperhydrated back to 193 pounds”

1-- I hated to see it change-- Change is the bare (without 'to') infinitive object complement of 'it', which is the object of 'see'. 'To see' is also an infinitive complement-- of 'hated'. There is no limitation on number of infinitives in a sentence.

Most people are fast to stop you before you get started but hesitant to get in the way if you are moving-- 'Started' is the -ed verb form used as a predicate adjective in what Quirk calls the 'resultant copula'. Some examples: grow tired, become irritated, end up married.

Also, do tenses in the same paragraph and sentence need to agree with each other? -- As a matter of style, narrative should usually be consistent in tense, but otherwise, tenses can vary with meaning even in the same sentence: I went skiing once in 1979, and I have been snowboarding several winters since then, but I really want to try tobogganing sometime, too.

Thanks for answering my question. One thing I still don't understand is how should I know if something is the "bare (without 'to') infinitive object complement" of something else. Do you happen to have a list of those verbs? Thanks

It is an open set; there is no list. Any infinitive without 'to' is called a 'bare' infinitive.
