新版四年级英语下册第5页怎么做

同学们好，我是你们的火锅老师，现在让我们一起学习第五页， please listen carefully and repeat let's learn these are our classrooms， these。 这些 are our classrooms， classrooms， classrooms keep the classroom clean keep the classroom clean don't be late don't be late don't eat in class don't eat in class put your hand up to speak put your hand up to speak turn off the lights after school turn off the lights after school look and see what can we say to these students what can we say to these students one put your hand up to speak two don't be late for school three don't eat in class four keep the classroom clean。 同学们，这一页的语法点就是我们学会祈使句。 在英文当中，祈使句表达人说话对对方的叮嘱、劝告、希望、禁止、建议等。祈使句通常省略他的主语 you， 而且无人称和数的变化。 那其实句在英文当中有四大句型，第一种是 do 型，肯定句是 do 加动词原型，比如说 keep the classroom clean。 否定句是 don't 加动词原型，比如我们说 don't eat in class。 第二种是 be 句型，肯定句是 be 加上形容词，比如说 please be nice。 那否定句是 don't 加 be 加形容词，比如说 don't be late 不要迟到。 第三种就是 no 句型的祈使句，它通常是 no 后面加逗名词或名词，比如说不要抽烟 no smoking 那 不要照相 no photos。 第四种就是我们之前了解到的 let 句型，它分为肯定句，比如说 let's go， let 后面加动词原型，否定句是 let 加 somebody， 某人加 not 加动词原型，比如说让他不要讲话 we can say let him not talk please。
