I've been going over some sample questions related to to TEFL and although I can identify most of the errors intuitively I'm struggling to come up with actual rules that the various examples violate. For two brief examples:
In the sentence:
I every evening watch television
Surely this sentence is clumsy and should be written as "Every evening I watch television" but is there some hard rule that necessitates subjects come directly next to their corresponding verbs? or is it something to do with the interpolated "every evening"?

Also, even more simply:
in the sentence:
She work for big company
Ok, the first error is that the person hasn't conjugated the third person singular of "work" properly as "works" and there's an "a" or a "the" missing, but does this second mistake violate anything that could be called a rule? I apologize for my obtuseness...

Or, 'I watch television every evening".
but is there some hard rule that necessitates subjects come directly next to their corresponding verbs? or is it something to do with the interpolated "every evening"?

No, there is no such rule. It's a matter of idiomaticity. It would be perfectly normal to use the adverbs frequency without a specific time or day between subject and verb, as in "I usually watch television every evening" or "I never watch television while I eat" etc. *"I every Friday watch" is just not idiomatic.
Also, even more simply: in the sentence: She work for big company Ok, the first error is that the person ... there's an "a" or a "the" missing, but does this second mistake violate anything that could be called a rule?

The rule is that normally a singular noun even a modified noun like "big company" takes an article but that a plural noun does not need the article: "She works for big companies" is perfectly acceptable, as is "She works for the big companies", but the latter is used when both speaker and listner know which companies those big companies are.
I apologize for my obtuseness...

That's not necessary. Everyone else here is obtuse at times.
