arrive为不及物动词，后面跟地点时，需要加介词in (大地方，如 arrive in Beijing)或at (小地方，如arrive at the bus stop)，如果后跟地点是副词时，则不加介词，如 arrive here/home
另：同义词组为get to。
2. on time 准时；按时
You must be on time. 你必须准时。
而in time为“及时”之意。
He arrived there in time. 他及时到了那儿。重点探究3. listen v. 听
listen为不及物动词，后接宾语时要加介词to，
如：listen to music 听音乐
而hear也为“听”，强调“听”的结果，即“听见”；listen则强调“听”的动作。如：
Listen! Can you hear someone singing?
听！你能听见有人在唱歌吗？重点探究4. wear v. 穿；戴
wear 强调“穿”的状态，还可表示“戴”的意思，如：His father always wears a black coat. 他爸爸总是穿一件黑色外套；而put on则强调“穿”的动作。如：It’s cold. Put on your coat. 很冷，穿上你的外套。5. bring v. 带来，拿来6. 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，有人称和数的变化，其后要跟动词原形。must着重于主观上自己认为有义务、有必要，没有人称和数的变化，其后要跟动词原形 。
e.g. She ________ clean the room every
week. 她每周都得打扫房间。
I _________ now.
我现在必须走。has tomust go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？课堂小结1.掌握以下重点单词、短语及句式
