must的否定式must not/mustn’t，意思是“不应该、禁止”,语气较强烈。例句：We mustn’t be late again.我们不应该再迟到了。但当must引出的.一般疑问句,肯定回答用must,否定回答用needn’t,don’t need to或don’t have to均可,但不用mustn’t,因为mustn’t表示“不许、禁止”的意思,与问句的原意不符。绛旓細浣犲ソ锛佷綘鎵缁欑殑鍙ュ瓙鍑嗙‘娓呮櫚鎵撳嚭鏉ユ槸鈥斺擲he must have been fifty.瑕佸彉涓哄惁瀹氬彞锛岄渶瑕佹敞鎰 must鐨勭壒娈婃剰鎬濆拰鐢ㄦ硶鈥斺攎ust 蹇呴』锛屼竴瀹氾紝琛ㄧず鑲畾鎬ф帹娴嬪垽鏂紝鍙兘鐢ㄤ簬鑲畾鍙ヤ腑銆must 鐨勫惁瀹氬舰寮 mustn't 琛ㄧず銆愮姝紝涓嶈銆戙傝琛ㄨ揪銆愪竴瀹氫笉锛屼笉鍙兘銆戯紝闇瑕佺敤 銆恈an't 銆戙傛墍浠ワ紝鎵...
