(4) shouldn't 的缩略形式注意： shouldn't = should not，不要与 don't / doesn't 混淆。 You shouldn't swim here.（正确） You don't should swim here.（错误） （三）谈论安全 (1) 提醒别人注意安全：Be careful. / You should be careful. (2) 表达某事不安全：It's not safe. / That's not safe! (3) 建议应该做的事：You should + 动词原形. 例：You should warm up first. You should walk slowly. (4) 建议不应该做的事：You shouldn't + 动词原形. 例：You shouldn't run on the stairs. You shouldn't push others. (5) 询问如何保持安全：How can we keep safe + 地点? 例：How can we keep safe at school? / How can we keep safe in PE class? (6) 表达身体感受：I feel + 形容词. 例：I feel tired. I feel happy. I feel sad. (7) 表达疼痛：My + 身体部位 + hurts. 例：My leg hurts. My arm hurts. My head hurts. （四）校园安全规则 (1) 在楼梯上：We should keep to the right. We shouldn't run on the stairs. We shouldn't jump from the stairs.
