If you           spit at all, please spit in the bucket(痰孟里)provided
A.mustB.shallC.should D.may
A

试题分析:must 表必须,一定;shall表法律,条文规定的必须;should 应该;may可能,结合句意:如果你一定要吐痰,请吐在所给的痰盂里。故选A.
点评:情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。can (could) 表示说话人能,可以,同意,准许,以及客观条件许可;will, would用于疑问句表示说话人向对方提出请求或询问,用 would 比 will 更婉转,客气。Shall, should表示命令,警告,允诺,征求,劝告,建议惊奇。
