erydayhaveto与musthaveto着重于客观的需要，含有“不得不”的客观强制性；must着重于主观上自己认为有义务、有必要。如：Shehastocleantheroomeveryweek.她每周都得打扫房间。Imustgonow

.Languagepoint:含有haveto的句子变一般疑问句或否定句时要借助助动词do/don’t或does/doesn’t；而含有must的句子变一般疑问句是直接将must提前至句首，变否定句是在must后加not。如：He

doesn’thavetodoit.他不必做那件事。Hemustn’tdoit.他不许做那件事。Doeshehavetodoit?他不得不做那件事吗？Musthedohishomework?他必须做他的作业吗？在否定句中，don’t/do

esn’thaveto表示“没有必要”，mustnot/mustn’t表示“不允许”。如：Youdon’thavetogothere.你不必去那儿。Youmustnot/mustn’tgothere.你不许去那儿。练一
