whose等在從句中充當(dāng)主語、賓語、表語、定語等成分連接副詞（作狀語）when、where、how、why在從句中作時間、地點、方式、原因狀語等成分依據(jù)“缺什么補什么”原則確定正確的連詞。所謂“缺什么補什么”是指從句與連詞之間的關(guān)系。如果句子中缺主語，指人用who，指物用what。如缺賓語，指人用whom，指物用what。如缺時間狀語用when；地點狀語用where。

原因狀語用why；方式狀語用how。如缺定語用what或which或whose。如什么都不缺用that，Whether表“是否”。devote...to...movepeopletotearsYuandevotedallhislifetodevelopinghybridrice
