Answer 1

B

B　句意：當(dāng)你不喜歡一件事情時(shí)，你應(yīng)該做的是改變它。不要抱怨�！癬_______you are supposed to do”為主語從句，該從句缺少賓語，表示“事物”且語境中并無選擇含義，故用what引導(dǎo)；“________you don't like a thing”為時(shí)間狀語從句，作are supposed to do的狀語，說明其時(shí)間，故用when引導(dǎo)。因?yàn)橹髡Z從句“What you are supposed to do”中含實(shí)義動(dòng)詞do，故is后的表語需為省去不定式符號的不定式，故change作表語。
