59

一、基础情态动词(can, may, must)

Can(能/可以)

- I can swim.(我会游泳。)

- You can help me with my homework.(你可以帮我做作业。)

May(可以/也许)

- It may rain tomorrow.(明天可能会下雨。)

- The cat may be sleeping.(猫可能在睡觉。)

Must(必须)

- You must wear a seatbelt.(你必须系安全带。)

- I must finish my homework before dinner.(我必须晚餐前完成作业。)

二、其他常用情态动词

Should(应该)

- You should brush your teeth every day.(你应该每天刷牙。)

- We should share toys with each other.(我们应该互相分享玩具。)

Will(将会)

- I will call you at 6 PM.(我会在6点给你打电话。)

- The party will start at 7 PM.(聚会将于7点开始。)

Would(将会,愿意)

- Would you like some juice?(你想要点果汁吗?)

- He would help if he had time.(他有时间会帮忙的。)

三、注意事项

情态动词后接动词原形,如 can do(能做)、 must finish(必须完成);

表示过去可能性用 could(can的过去式),如 He could swim when he was younger(他小时候会游泳);

需要结合语境选择合适情态动词,例如建议用 should,请求用 can,禁止用 must not

建议先从 can, may, must开始练习,再尝试 should, will, would等进阶用法。可通过制作卡片或编故事的方式巩固记忆。
