1. must, can’t
1) must 必须、必要（must更偏向主观上的“必须”而have t更强调客观理由） ※ 回答must问句时, 否定回答用needn’t或dn’t have t, 不能用mustn’t。 — Must we hand in ur exercise bks tday? — Yes, yu must. / N, yu dn’t have t.2) can’t 在口语中代替mustn’t时，表示禁止或不准。 Yu can’t play ftball in the street. 你不能在街上踢球。

wuld ：“总是，总要”，过去反复发生的动作或某种倾向。used t： “过去常常”，现在已没有这种习惯※ used t 可与状态动词连用, wuld不可以e.g. He used t be a quiet by. ( ) He wuld be a quiet by. ( )

过去将来时的基本结构是“wud+动词原形”, 否定式是在wud后面加nt。如:Jeff knew he wuld be tired the next day.杰夫知道他第二天会很累。He prmised that he wuld nt pen the letter until 2 ’clck.他许诺两点钟之前不会打开信。
