B 从第二个分句“他太矮了”可以推知说话者持否定态度，neednt意思是“没有必要”，与语境不符。 2. C 根据句意“我已经告诉她怎样到那儿，但是或许我应该给她写下来”可知，说话者含有“后悔、遗憾”的意味，应使用“情态动词+完成式”形式，“must+完成式”表示对过去的肯定推测，“should+完成式”才表示虚拟意义。 3. C 根据第二分句“否则的话他就会给我打电话了”可知“Jack肯定还没到”，“cant+完成式”意思是“根本不可能”。 4. A 从第二分句可知，这是妇女和儿童专用候车室，因此你“不准”坐在这儿。mustnt表示“禁止，不准”。 5. B can在此表示许可。 6. D 从后一句“他喜欢开车”可知说话者把握不大。must not不表示推测，can not的语气太绝对，意思是“根本不可能”。 7. D shall用于第二、三人称，表示说话人给对方的命令、警告、允诺、威胁等意思。 8. C should在此表示惊讶的感情色彩，意思是“竟然”。 9. B 对祈使句的肯定回答用I will；否定回答用I wont。10. D 根据句意“我今天上午在会议室没见到她”， 所以“她根本不可能在会上发言”。表示“根本不可能”用cant/couldnt have done形式。情态动词专项练习11) You_ all those clothes!
