{01}“I know she was in because I heard her radio, but she didn’t open the door.” “She___the bell.” A.may not be hearing B.may not have heard C.must not have heard D.must not be hearing 解析：考查情态动词。根据语境可知为对过去事情的推测，故用情态动词+ have done。may have done过去也许做过某事。根据句意为：她也许没有听到铃声。故选B。
本题选B。

{02}My little son _____ out alone at night. A.dares not go B.dares not to go C.dare not to go D.doesn’t dare to go 解析：考查动词。句中dare作实意动词，故有形式的变化，doesn’t dare to go =" dare" not go。句意：我小儿子晚上不敢单独外出。
本题选D。
