解析：

答案： 　　1．The classroom is always kept clean. 　　2．He has been made to do the work by his mother. 　　解析：如果主句結(jié)構(gòu)的謂語動(dòng)詞后接復(fù)合賓語(賓語＋賓語補(bǔ)足語)，變被動(dòng)語態(tài)時(shí)，只能將賓語變?yōu)楸粍?dòng)結(jié)構(gòu)的主語，賓語補(bǔ)足語則成了被動(dòng)結(jié)構(gòu)中的主語補(bǔ)足語。注意感官動(dòng)詞see, watch, hear, feel等和使役動(dòng)詞make, let, have等后接不帶to的不定式短語作賓語補(bǔ)足語時(shí)，變被動(dòng)語態(tài)時(shí)須補(bǔ)上to.
