Veelgemaakte fouten
재활용을 해야 있어요재활용을 해야 해요The obligation pattern is -아/어야 하다, not -아/어야 있다. Use 해야 해요 for must/have to.
에너지를 절약하여야 해요에너지를 절약해야 해요절약하다 is a 하다 verb. Its contracted form is 절약해야 하다, not the longer literary 하여야.
환경이 보호해야 해요환경을 보호해야 해요보호하다 (to protect) is a transitive verb — 환경 is the object and needs 을/를, not the subject marker 이.
쓰레기 분리해서 버리야 해요쓰레기를 분리해서 버려야 해요버리다 (to throw away) needs the obligation suffix -어야 하다: 버리 + 어야 = 버려야. Also 쓰레기 needs the object marker 를.
지구를 지켜야 돼요?지구를 지켜야 해요지켜야 돼요 is not wrong, but at A2 level 지켜야 해요 is the standard form taught. Both express obligation but 하다 is more foundational.
