12．-How often do I need to feed the birds？
-They ________ food every day，or they will be hungry．（　　）
A．must giveB．mustn't give
C．must be givenD．mustn't be given

分析 -我需要多久喂一次鳥？-它們每天都要喂，否則它們會饑餓．

解答 答案：C．答句中they代指the birds，是動作的承受者，所以用被動語態(tài)；又根據(jù)or they will be hungry．可知是每天必須喂，所以用情態(tài)動詞的被動語態(tài)，其構(gòu)成為：情態(tài)動詞+be+過去分詞，give的過去分詞為given，故選C．

點評 本題考查情態(tài)動詞的被動語態(tài)，其構(gòu)成為：情態(tài)動詞+be+過去分詞，要掌握其表示的含義，在不同的語言環(huán)境中達到熟練掌握的目的．
