Comparing "benlai" and "yuanlai"

If something was originally a certain way, or "should be" a certain way, the Chinese words used are often 本来 (běnlái) and 原来 (yuánlái). 本来 (běnlái) is usually an adverb while 原来 (yuánlái) could be either an adjective or an adverb.

本来 + 是 for a Change of Plans

If something happened unexpectedly later, 本来 is preferred rather than 原来 considering there is a change of the original situation. 本来 means "originally." Since the action has already happened, the pattern 是⋯⋯的 is suggested here. 是 is optional.

Subj. + 本来 + 是 + [（不）要 / 会 / 应该 ] + Verb + 的，但是 / 可是⋯⋯

本来 + 就 for Common Sense Statements

本来 is used when something is common sense. There are certain expectations for the speaker and listener. Since there is no real English equivalent, it is best translated as "it goes without saying." It can also be translated to "supposed to," following it with a certain expectation.

Structure

Subj. + 本来 + 就 + 很 / 不 + Adj.

本来 + 就 for Emphasis

If you've got an opinion to express after stating how it "should be" or "should not be," then 本来就 will help you sound more convincing. The end of the sentence usually has an imperative or rhetorical question that leads to an opinion or suggestion, emphasizing the tone.
