依据“缺什么补什么”原则确定正确的连词。所谓“缺什么补什么”是指句型结构与连词之间的关系。如果句子中缺主语，指人用who，指物用what；如缺宾语，指人用whom，指物用what；如缺时间状语用when；地点状语用where；原因状语用why；方式状语用how；定语用whose或which；什么都不缺用that。
Complete the sentences using what, whether, where,
when， who, why, how or that.
1.(_____ is needed for success) is your hard work.
3.(_____ we will go tomorrow )hasn’t been decided yet.
2.(______ they will arrive )has been told to the teacher.
