23、must为肯定推测，表示“一定”，could为不肯定推测，表示“可能”，这样就能选出正确答案。22What does the sign over there read？“No person_smoke or carry a lighted cigarette,cigar or pipe in this area.”Awill BmayCshall Dmust-那边的牌子上写的是什么?-任何人不得在本地区吸烟或携带点燃的香烟、雪茄或烟斗。A. will表示现在的意志、愿望等，意为要，希望； B. may表示许可，或用于请求许可，意为可，可以；C. shall在陈述句中用于第二人称或第三人称，表示
