You can't run on the road. 解析：主语 you + 情态动词否定式 can't + 动词原形 run + 地点状语 on the road。 2.We must follow the traffic rules. 解析：主语 we + 情态动词 must + 动词原形 follow + 宾语 the traffic rules。 3.The traffic light is green. 解析：主语 the traffic light + be 动词 is + 表语 green。 4.Let's take a bus to go home. 解析：祈使句结构 Let's + 动词原形 take + 宾语 a bus + 目的状语 to go home。 5.There are ducks on the road. 解析：there be 句型 There are + 主语 ducks + 地点状语 on the road。 六、单项选择。 1. B 解析：情态动词 can 后接动词原形，take a bus 是动词短语，意为 “乘公交车”；by bus 和 on a bus 是介词短语，不能直接跟在 can 后。 2. B 解析：根据后一句 “有很多汽车和自行车”，可知道路很 “繁忙”，busy 符合句意；safe（安全的）、close（近的）不符合语境。 3. C 解析：根据后一句 “很危险”，可知 “不能在路上踢足球”，can't 表示禁止，符合句意；can（能）、must（必须）不符合语境。 4. B 解析：答句回答 “骑自行车上学”，是出行方式，用 How（怎样）提问；What（什么）、Where（哪里）不符合答句逻辑。 5. B 解析：固定搭配 stay closed 意为 “待在安全的地方、保持待着的状态”，closed 是形容词作表语；closing（现在分词）、close（动词 / 形容词 “近的”）不符合搭配 7、 【新情境·制作安全海报】Mike和Sarah正在为班级制作道路安全海报。请根据对话内容，从方框中选择合适的句子，将序号填在横线上, 使对话完整通顺。 答案：1.C 2.E 3.D 4.B 5.A 拓展练 8、 【任务型阅读·安全出行】阅读材料，完成任务。 任务一：判断正误​ 1.
