problem和question都有“问题”之意,但它们的区别是:problem通常指客观存在的等待解决或决定的问题,与它搭配的动词一般是workout或solve;而question常指主观上产生的需要考虑、回答或说明的问题。它常与ask和answer搭配使用。如:Thegovernmentmustsolvetheproblemofthetraffic.政府必须解决交通问题。对点自测用problem或question完成下列句子1.Ifyouhaveany,pleasecallmeandIcanansweryou.

2.Themathisnotdifficult.Icanworkitouteasily.

【答案】1.blem[命题点二]Mustweexercisetopreventtheflu?我们必须做运动来防止流感吗?

◎用法总结:1.must和haveto都有“必须;不得不”的含义。must表示说话人的强烈要求,含有“命令;义务”等含义,侧重说话人的主观意愿和看法;它没有时态和人称的变化,后跟动词原形。如:Youmustwaitinline.你必须排队等候。2.haveto则表示客观原因“不得不”做某事,侧重于外界因素的限制而“被迫”,一般用来表达客观的需求。haveto有人称和数的变化,第三人称一般现在时的形式是hasto,一般过去式用hadto。如:Tomhastostayathomebecauseitisraininghardnow.现在正下大雨,汤姆必须待在家里。3.对含must一般疑问句的否定回答,不能用mustn't而要用needn't或don'thaveto。对含有haveto的一般疑问句的回答,要根据时
