原因状语用why；方式状语用how。如缺定语用whose或which。如什么都不缺用that，Whether表“是否”。Task2:主语从句怎么考？1._________theywillcomehasn’tbeenmadepublic.2.________heattendedthemeetingornotwasn’tquiteclear.3.________hesolvedtheproblemsuccessfullysurprisedusall.4.However,_______concernedhimmostwasthatfarmersoftenhadpoorharvests......5.________was
