(我们现在回家好吗?)或者Shall I invite her to join us? (我要不要邀请她加入我们?) 2. 在陈述句中,shall表示允诺、命令、警告、威胁等。如:You shall get the book two days later.(你将在两天后得到这本书。)(表示允诺)或者He shall end up in prison if he goes on like this.(如果他继续这样下去,他最终会进监狱的。)(表示警告) 3. 当shall用于表示在规定、条约、法规等中的必须、应该时,一般用于第三人称。如:All the students shall obey the school rules.(所有的学生都应该遵守校规。)或者No candidates shall leave the classroom before 10 o’clock.(考生在10点前不得离开考场。) 4.
