We told him to consult the doctor,?which?advice he took.

這里的which能否改為whose?

which不可改為whose，改為whose意思就變了。which advice 指代 toconsult the doctor。句子意思為：大家讓他去看大夫，他采納了大家的這個建議（即他去看大夫了）。假如改為whose，則whoseadvice意為the doctor's advice. 意思就完全不同了。原句的意思也可以用并列句表示，即 We told him to consult the doctor, and he took this advice. 當大家把這個并列句改為關(guān)系分句時，僅需刪去并列標記and, 然后用關(guān)系限定詞which替換指示限定詞this，并將whichadvance移至主語前引導關(guān)系分句即可，就提問中的句子。
