研究背景有些同学的爸爸嗜烟如命,只要一回到家,屋子里就乌烟瘴气,同学和妈妈深受其害,多次向爸爸进行规劝,可他们就是“屡教不改”。再向大家介绍一次学校召开家长会后的情况。家长会后第二天我们进班,一推开门,一股难闻的烟臭味就扑鼻而来。再往地上一看,我们顿时傻了眼,满地都是烟头,桌上也有,更可气的是桌洞里也塞了几个。我们打开了教室里所有的门窗,可那讨厌的“烟臭味”像幽灵似的久久不肯散去。哎,这些家长到底怎么了! Research Background Some classmates’ daddy is a smoker. As soon as he returns home, the house is suffocating and his classmates and his mother are deeply harmed. They repeatedly advise Dad, but they are “repentant.” Then we will introduce the situation after a school held a parent conference. We entered the class the next day after the parent conference. As soon as we opened the door, an unpleasant smell of smoke whistled. Looking to the ground again, we suddenly stared blindly, covered with cigarette butts on the floor, and there was also a table on the table. Even more exasperating was that there were several holes in the table hole. We opened all the doors and windows in the classroom, but the unpleasant “smoke smell” was like a ghost for a long time. Hey, what happened to these parents?
