12、 表示征求对方意见或请求指示（此时，只用于第一、三人称）；shall还可用于表示意图、意志、允诺、命令等必然结果（此时shall只能用于第二、三人称，要重读且不能缩写），但shall所表示的意志是说话人的意志，而非句子中主语的意志。如：Shall we set off for school now?(请求)Shall I close the door?(征询意见)Every student shall carry his ID card at school.(规定)You shall return home at 8 oclock.(命令)2.should 表示劝告、建议等，译为“应该”。如：
