D 1 mustn't/can't/shouldn't 2 can 3 mustn't, walk, quickly 4 mustn't, run, skate
E 1 looking for 2 Look at 3 looks after 4 Look out 5 look out for

【解析】
D部分：
1. 原句为否定祈使句，表达“禁止/不应该在此左转”，可用mustn't（禁止）、can't（不能）、shouldn't（不应该）替换，构成同义句。
2. 否定句改肯定句，去掉否定词cannot，替换为肯定形式can即可。
3. must的否定形式为mustn't，改为否定句时在must后加n't，其余部分不变，即You mustn't walk quickly。
4. 两句均为mustn't引导的否定祈使句，合并时用or连接并列动作run和skate，构成You mustn't run or skate on the road。
E部分：
1. 句意是寻找高小姐，look for表示“寻找”，结合I'm可知用现在进行时looking for。
2. 句意是看图片，look at表示“看”，祈使句开头首字母大写，故填Look at。
3. 句意是爷爷照顾猫，look after表示“照顾”，every day表明用一般现在时，主语是第三人称单数，故填looks after。
4. 句意是提醒小心，look out表示“小心”，祈使句开头首字母大写，故填Look out。
5. 句意是过马路留意车辆，look out for表示“留意”，should后接动词原形，故填look out for。
