She has the flu.（那不可能是莉莉，她感冒了。）。表可能性与能力（can/could/may/might）can/could + 动词原形：“可能；能够”，could 语气更委婉或可能性更低；may/might + 动词原形：“可能，可以”，might 可能性比 may 小；教材例句：Crayons may carry viruses.（蜡笔可能携带病毒。）Can you share your notes with her?（你能把笔记分享给她吗？）He might not come today.（他今天可能不来了。）。表义务与意愿（must/can）must + 动词原形：“必须，一定要”，强调主观义务；can + 动词原形：“可以，能够”，表达助人意愿或许可；教材例句：There must be something for me to do.（我一定能做点什么。）We can go and ask if she needs help.（我们可以过去问问她是否需要帮助。）。（二）核心句型（100% 贴合教材）提出助人意愿：What can I do to help? → I can donate some books.；描述助人经历：Who did you help? How did you help? → I helped an old woman find her home.；表达感激：How do you feel about their help? → I'm very grateful to them.；策划助人活动：What challenges may we face? → We may need more people to join us.；谈论善意传递：Why is passing on kindness important? → It creates a circle of goodwill.。
