A 3. B 4. B 5. C 七、【新素养·能力提升】句型转换- 答案： 1.can't 解析： 含有情态动词can的肯定句变否定句，直接在can后加not，缩写为can't。 2.Don't wear 解析： 祈使句的否定形式是在动词原形前加"Don't"。 3.Is 解析： 含be动词(am/is/are)的句子变一般疑问句，将be动词提到句首，首字母大写，句末用问号。 4.Are there 解析： There be句型变疑问句，将be动词(are)提到there前，其他部分顺序不变。 5.How do 解析： 对交通方式提问用特殊疑问词"How"。原句谓语是实义动词go，所以用助动词do构成问句。 拓展练 八、【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. (F) 原文依据： "When you walk on the road, always use the pavement." 解析： 原文明确说"步行时必须走人行道(pavement)"，而不是"如果小心就可以走在马路上"。"always"表示"总是、必须"，语气绝对。所以即使小心，也不能在马路上走。 2. (T) 原文依据： "To cross the road, find a zebra crossing." 解析： "zebra crossing"就是斑马线。原文建议过马路时"find a zebra crossing"，即"找一条斑马线"，这与"应该在斑马线处过马路"意思一致。 3. (F) 原文依据： "Look left, then right, then left again before crossing." 解析： 原文清楚的过马路观察顺序是：先左→再右→再左。题目说"先右看"，顺序错误。在中国（靠右行驶）确实应该先看左边，因为左边来车更近、更危险。 4. (F) 原文依据： "Never run across the road." 解析： "Never"表示"绝对不要"，原文明确禁止跑着过马路。快速跑过马路容易摔倒或被司机误判，反而更危险。 5. (F) 原文依据： "When you ride a bike, wear bright clothes..." 解析： 原文建议穿"bright clothes"（鲜艳/亮色衣服），这样更容易被司机看到。而"dark clothes"（深色衣服）在夜间不易被发现，不安全。尤其夜间骑自行车，穿深色衣服是非常危险的行为。 任务二：根据材料内容完成，合理即可。 2 / 2 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
