Arrive的用法
Don’t arrive late for class. (教材P19 1a)
arrive是不及物动词，具体用法如下：
若接地点名 词，要加介词in或at。 in后接大地方(如城市或国家)。 When did you arrive in Dalian 你是什么时候到大连的？
at后接小地方(如学校、酒店或车站)。 I usually arrive at the bus stop at 6:30 every morning. 我通常每天早晨6:30到公共汽车站。
若接地点副词(here/there/home等)，则不用介词。 My father arrives home late every night. 我爸爸每天晚上很晚到家。
【辨析】arrive, get与reach
arrive（in/at） arrive为不及物动词，其后跟表示地点的副词here, there, home，abroad等时，不需要加任何介词；其后跟地点名词时，则要加介词，即arrive in +大地点(国家、大城市等)，arrive at+小地点(镇、家、店等)”
get（to） get意为“到达”时，为不及物动词，其后跟表示地点的副词here，there，home等时，不需要加任何介词；其后跟地点名词时，则要加介词to，即“get to十地点名词”
reach 及物动词，意为"到达"，其后直接跟地点名词。
eg：He arrived in Jinan yesterday. 他昨天就到济南了。 I arrived at the restaurant an hour ago. 我一个小时前到达了这家餐馆。 When/How do you get to school 你什么时候/如何到学校？ How do you get to there 你怎么去那里（去掉介词to） They reached London last night. 他们非晚到达了伦敦。
You must be on time. (教材P19 1a)
must 为情态动词，无人称和数的变化。情态动词不能单独作谓语，必须与动词原形一起构成谓语。本句的谓语由“must+be”构成。
eg：We must go at once. 我们必须马上就走。
You must obey the school rules. 你必须遵守校规。
have to 意为“必须；不得不”，表示客观的需要，有人称、数、时态的变化。don’t/doesn't have to意为“不必”。
must 意为“必须”，表示说话人主观上的看法，只有一种形式。mustn’t意为“禁止”。
You must be on time. (教材P19 1a)
【辨析】on time 与in time
on time 按时；准时 指按规定或指定的时间
in time 及时 指不迟到或接近规定的时间
eg：The plane takes off on time. 飞机按时起飞。
An ambulance arrived in time. 一辆救护车及时赶到。
