情态动词 can, would, must 的用法

情态动词	用法	例句
can	表示能力或许可，用于现在和将来。	Can you swim? (能力) You can go now. (许可)
would	表示礼貌的请求或建议，语气比 can 更委婉。	Would you like some tea? (请求) I would like to go. (意愿)
must	表示必须，强调主观义务或必要性。	You must finish your homework. (必须)
have to	表示客观需要或外部规定，意为“不得不”，有人称和数的变化。	I have to get up early tomorrow. (我明天不得不早起。)

对比 must 和 have to:

• I must go now. (我感觉现在必须走,主观意愿)
• I have to go now. My mom is waiting for me. (我不得不走，因为妈妈在等我,客观原因)

be going to 结构 (表示将来)

• 结构: 主语 + be动词 (am/is/are) + going to + 动词原形 + 其他
• 用法:
  1. 表示计划、打算做某事。
     • I am going to study for the test tonight. (我今晚打算为考试学习。)
  2. 根据现在迹象，预测不久将发生的事。
     • Look at the dark clouds. It is going to rain. (看那些乌云，要下雨了。)
