文法句型

linking verb + as if + clause (='that' + clause)

用法筆記

Unlike sense 1 (APPEARS TO BE), this use does not compare the situation to a hypothetical scenario. 'It seems as if the meeting has started' simply states an observation, equivalent to 'It seems that the meeting has started.' In informal conversation, 'like' often replaces 'as if' in this pattern ('It looks like it will rain'). In more formal writing, 'as if' or 'as though' is preferred.

常見錯誤

❌It seems as if.' (incomplete)
✅It seems as if the meeting has already started.
💡'as if' must introduce a full clause, not stand alone.
