今天是我上学的第一天。
其中一些规定
follow/obey the rules 遵守规则
break the rules 打破规则
上学迟到
情态动词，强调主观上的需要，必须
后面接动词原形
准时，按时
bring sth to sp.
=bing sb. sth.
把某物带到某个地方
穿校服
交际用语，我知道了，我明白了
have to强调客观上的需要，不得不
保持安静，=keep quiet
副词：quietly
重要的，常用句型：
it's important for sb. to do sth.
辨析： have to与must
have to着重于客观的需要，含有“不得不”的客观强制性must着重于主观上自己认为有义务、有必要。
如：
She has to clean the room every week.
她每周都得打扫房间。
I must go now.
我现在必须走。
含有have to的句子变一般疑问句或否定句时要借助助动词do / don’t或does / doesn’t；而含有must的句子变一般疑问句是直接将must提前至句首，变否定句是在must后加not。如：
He doesn’t have to do it. 他不必做那件事。
He mustn’t do it. 他不许做那件事。
Does he have to do it
他不得不做那件事吗？
Must he do his homework
他必须做他的作业吗？
在否定句中，don’t / doesn’t have to表示“没有必要”
must not / mustn’t表示“禁止；不允许”。
如：
You don’t have to go there.
你不必去那儿。
You must not / mustn’t go there.
你不许去那儿。
