解析
【分析】
首先要明确题目核心是围绕“安全过马路”的行为规则,用情态动词must(表示必须做的正确行为)和mustn't(表示禁止做的危险行为)进行问答。先区分提示短语:look for a zebra crossing、look at the traffic lights是安全过马路需要遵守的正确行为,对应must;play football on the road、play on the zebra crossing是危险的违规行为,对应mustn't。然后按照题目给出的S1提问句式,分别针对两类行为组织问答内容即可。
【解析】
我们根据提示的行为和must/mustn't的用法,可组成以下四组问答:
示例1:
S1: To cross the road safely, what must you do?
S2: I must look for a zebra crossing.
(说明:look for a zebra crossing是安全过马路的必要行为,所以用must提问和回答)
示例2:
S1: To cross the road safely, what must you do?
S2: I must look at the traffic lights.
(说明:look at the traffic lights是安全过马路的必要行为,所以用must提问和回答)
示例3:
S1: To cross the road safely, what mustn't you do?
S2: I mustn't play football on the road.
(说明:play football on the road是危险的违规行为,所以用mustn't提问和回答)
示例4:
S1: To cross the road safely, what mustn't you do?
S2: I mustn't play on the zebra crossing.
(说明:play on the zebra crossing是危险的违规行为,所以用mustn't提问和回答)

talk loudly in the library.答案
1 take 2 must 3 students 4 mustn't
解析
【分析】
我们可以结合句意、生活常识和语法知识逐个分析每个空:
1. 第一句表明公园很远,需要选择合适的出行方式,首字母为t,“take the bus”是固定搭配,意为“乘坐公交车”,且情态动词can后需接动词原形,符合语境要求。
2. 第二句提到红灯,根据交通规则,红灯时必须停下,首字母为m,情态动词“must”用于表达义务、强制性规则,契合句意。
3. 第三句场景是学校,结合首字母s,过马路的主体应该是学生,some后接可数名词复数,所以用student的复数形式students。
4. 第四句场景是图书馆,图书馆需要保持安静,禁止大声说话,首字母为m,情态动词“mustn't”表示“禁止、不允许”,符合该公共场所的规则。
【解析】
1. 句意:公园很远,你可以______公交车。结合首字母t,固定短语take the bus表示“乘坐公交车”,情态动词can后接动词原形,故填take。
2. 句意:红灯亮时,你______停下。根据交通规则,红灯时必须停下,情态动词must表示“必须”,用于表达强制性规则,首字母m匹配,故填must。
3. 句意:这里是一所学校。一些______正在过马路。结合学校场景和首字母s,student(学生)符合语境,some后接可数名词复数,故填students。
4. 句意:你______在图书馆大声说话。图书馆内禁止大声喧哗,情态动词mustn't表示“禁止、不允许”,首字母m匹配,故填mustn't。
【答案】
1 take 2 must 3 students 4 mustn't

on the road.答案
1 mustn't/can't/shouldn't 2 can 3 mustn't, walk, quickly 4 mustn't, run, skate
解析
【分析】
1. 第1题:原句是祈使句的否定形式,表达“禁止/不应该在此左转”的含义。要改写为以We为主语的句子,需用情态动词的否定形式来传递禁止、不允许或建议不要做某事的语义,mustn't(禁止)、can't(不能)、shouldn't(不应该)均符合要求。
2. 第2题:原句是含情态动词cannot的否定句,改为肯定句时,只需将否定形式cannot替换为对应的肯定形式can,其余内容保持不变即可。
3. 第3题:原句是含must的肯定句,改为否定句时,直接在must后加not(缩写为mustn't),后面的动词短语walk quickly无需改动,以此表达“你不准快走”的否定含义。
4. 第4题:两个句子均为"You mustn't + 动作 + on the road"的否定句式,且动作都是道路上的行为。合并时保留一个mustn't,用并列连词or连接两个动作run和skate,就能将两句合并为一句,准确表达原句的禁止含义。
【解析】
1. 原句"Don't turn left here."是禁止左转的祈使句,转换为We作主语的句子,用情态动词否定形式表达禁止/不允许的语义,故填mustn't/can't/shouldn't。
2. 原句"Helen cannot find a zebra crossing near her."中cannot是can的否定形式,改为肯定句时将cannot替换为can,故填can。
3. 原句"You must walk quickly."的否定形式为在must后加not(缩写为mustn't),动词短语保持不变,故填mustn't walk quickly。
4. 两句都是"You mustn't + 动词短语 + on the road"的结构,合并时保留一个mustn't,用or连接两个动词run和skate,故填mustn't run skate。
【答案】
1 mustn't/can't/shouldn't
2 can
3 mustn't, walk, quickly
4 mustn't, run, skate
