网友回答
A. should
B. must
C. would
(答案→)D. shall
解析： shall用于第二、三人称，表示说话人的强烈愿望，具有命令、警告、威胁、允许的含意。意思是“必须、应该、可”。句意是“我发誓她过生日一定会得到一件好的礼物。”“那对她将是一个大惊喜。”如：
Rose shall have a new dress at Christmas.
露丝在圣诞节定会有一条新裙子。
Candidates shall remain in their seats until all the papers have been collected.
试卷全部收回后，应试人才可离开座位。
