在线课程【答案】
【解析】1.day改为days
考查名词复数。根据前面的these 可知day要用复数，故用days.
2.littered改为litter
考查谓语动词。people break traffic rules and litter everywhere .break 和 litter是并列的谓语动词，故也要用一般现在时。主语是people，故.littered改为litter
3.with改为to
考查固定搭配。do harm to …对……造成伤害。故.with改为to。
4.a改为an
考查不定冠词。名词effort是元音开头的，要用不定冠词an.,故a改为an。
5.him改为me
考查人称代词。从As for him, I will bear traffic rules in mind.中可知，主语是我，所以him要改为me.
6.turn 改为turns
考查谓语动词。本句子I’ll never cross a road until the traffic light turn green.中的turn的主语是the traffic light，是单数，故要用turns.
7.添加never/not
考查否定句。上文：至于我，我会记住交通规则的。如果我骑自行车，直到交通灯变成绿色，我才过马路。可推断出“如果我步行，我决不会忘记走斑马线”因此要用否定式。故添加never/not.
8.删去as
考查连词。Meanwhile, I will make it as my duty to help keep our environment clean本句中it是形式宾语，真正的宾语是后面的动词不定式，所以as 是多余的，故要删去as。句意：我会尽我的责任来帮助保持我们的环境清洁。
9.or 改 为 and
考查并列连词。是保持环境的清洁和健康。是并列关系。故要or 改 为 and
10.possibly改为possible
考查形容词。I will help clean up the roadside litter whenever（it is ）possibly只要有可能，我就帮忙清理路边的垃圾。从句意可知whenever从句中省略了it is ,possible作从句的表语，故possibly改为possible。
