Don ’t eat in class.要点详解1. arrive, reach, get以上三词均可表示“到达、抵达”之意，但用法不同。
arrive 后接at （小地方）或in （大地方——城市、国家）reach 直接连“某地”，get 加to 后再接某地。
如：I arrived in Beijing yesterday.They reached the Great Wall by bus.How can I get to the TV station?若要表示“到家/这儿/那儿”时，用arrive / reach / get 均可。
即：arrive / reach / get home / here / there2. in class 和in the classin class 表示“在上课”，而in the class 表示“在班上”。
Don’t talk in class.上课时不要谈话。
There are 40 students in the class.这个班有40位学生。
类似的短语还有：at table at the table in hospital in the hospital out of question out of the question in front of in the front of 在进餐在桌上（生病等）住院在医院毫无疑问不可能的在……的前面在……的前部⎧⎨⎩⎪⎧⎨⎩⎪⎧⎨⎩⎪⎧⎨⎩⎪3. have to 和mustmust 表示“必须、应该”，是从主观出发的，同时must 意味着一种“责任”与“义务”。
如：We must help our parents do some housework.have to “必须”“不得不”，常表示受外界环境、条件所迫要做的事。
如：There is nothing in the fridge. I have to go shopping now.4. else 其他的else 表示“其他的，此外”，常被置于特殊疑问句、不定代词之后。
人教版丨七年级下册英语4单元词汇/句型精讲（附练习题及答案）Unit4一、词汇精讲：1. arrive1）arrive 意为“到达”。
arrive at+小地点，arrive in +大地点。
例如：I will arrive in Beijing next week. 我下周到北京。
I arrived at the small village on a cold morning.在一个寒冷的早晨我到达了那个小村庄。
2）arrive 后面跟地点副词here, there, home时，不需要跟介词。
例如：arrive home 到家arrive here 到这儿注意：arrive late for与be late for是同义短语，都表示“做某事迟到”的意思。
arrive late for 强调动作晚，be late for 侧重状态晚。
例如：Don’t arrive late for the next test.＝Don’t be late for the next test.下一次考试不要再迟到了。
2. listenlisten 是不及物动词，意为“听,倾听”，强调听的动作，后面接宾语时要加上介词to。
例如：We should listen to the teacher carefully.我们应该认真听老师讲课。
Listen! Someone is singing in the garden.听! 有人在花园里唱歌。
拓展：hear, listen和sound的辨析三个词都有“听”的意思，具体区别如下：hear 意思是“听说，听到”，侧重听到的内容。
例如：I heard someone cry in the next room last night.昨晚我听见有人在隔壁哭。
listen意思是“听”，侧重听的动作。
例如：Listen! Someone is crying.听！有人在哭。
sound作动词讲时是连系动词，意为“听起来”，后面跟形容词作表语，构成主系表结构。
