评估问题 / Assessment
当{{name}}写作时，是否能选用像"must"、"might"、"could"和"should"这样的词来表达某事是确定的、可能的，还是只是一个想法，而不是把每个动作都当作确定发生的？
When {{name}} writes, do they choose between words like "must", "might", "could", and "should" to show whether something is certain, possible, or just an idea — rather than treating every action as definite?
