保持教室干净怎么翻译英语

今天我们学习第五页 let's learn these are our class rules。 这些是我们的课堂规则。 class rules 课堂规则 rules 把 s 去掉。 rule 是 一条规则，这里要加 s。 变成复数形式是因为这里的规则不止一条。有很多条规则，所以是 class rules keep the classroom clean keep 是 动词原形。保持 the classroom 名词教室 clean 形容词干净的 保持教室干净。 put up your hand to speak put up。 举起 hand 手，举起你的手发言就是举手发言。 don't be late 不要迟到 don't eat in class。 不要在课堂上吃东西。 turn off the lights after school turn off。 关闭。它的反义词是 turn on 打开 turn off the lights of school。 放学后关灯。注意的是，这里的句子都是祈使句，祈使句表示命令，请求或提醒别人。这样句子一般都是省略主语的。 它分两种形式，一个肯定式，一个否定式。肯定式动词原形加其他 比如 keep the classroom clean keep 动词原形加其他。 put up your hand to speak put up 是 动词短语原形加其他。否定是 don't 加动词原形加其他 don't eat in class don't 加动词原形 eat 再加其他 don't be late don't 加动词原形 be 再加其他 look and see。 看一看，说一说 what can we say to these students say 说 these students 这些学生，我们可以对这些学生说些什么呢？ 咱们看第一幅图，小朋友上课举手发言。我们可以说 put up your hand to speak put up。 是 动词短语原形。第二幅图小朋友迟到了，所以要说 don't be late。 这是歧视句的否定式。 don't 后面跟动词原形 be。 第三幅图，小朋友在课堂上吃东西，那就要提醒 don't eat in class eat 也是动词原形。第四幅图地面脏脏的，我们要保持教室干净。所以说 keep the classroom clean keep 是 动词原形开头的肯定起始句， okay read after me let's learn these are our class rules class rules keep the classroom clean put up your hand to speak don't be late don't eat in class turn off the lights after school look and say what can we say to these students。
