知识点：
1.【辨析 have to 与 must】
表达意见上的差异： must 表示说话人的主观意图和要求，相当于汉语中的“必须”；
have / has to 表示由于外部环境、情况、习惯等的客观需要，相当于汉语中的“不得不”。
如： You must do your homework now. 现在你必须做你的功课。
He has to study late into the night to pass the exam. 为了通过考试，他不得不学习到深夜。
（2）在否定句和疑问句中，have to 需借助于助动词do 相关形式，而must 则直接用mustn’t 或将must 提到句首。如：
Your mother doesn’t have to do that now. 你妈妈现在不必做那件事情了。
You mustn’t play football in the street after class. 放学后，你们一定不要在街上踢足球。
（3）must 不能与其他助动词will，shall 等连用，因此这种情形下要用have to。 Must 没有过去式，因此用于过去时应用had to （表示过去必须做，并且做到了）。如：
Shall we have to meet at the gate of the school 我们必须在校门口相见吗？
He had to get up early to catch the early bus. 他不得不起早床，去赶早班车。
（ ）1. You __________ take me to the station. My brother is taking me.
A.can’t B. mustn’t C. shouldn’t D. doesn’t have to
（ ）2.We ________wait until the traffic light turns green when we cross the road.
A.must B. can C. need D. may
（ ）3. Bob can not come out to play because he __________help his dad in the garden.
A.can B. has to C. have to D.must
（ ）4. -- Must I clean the window now -- No, you _______.
A.mustn’t B. needn’t C. can’t D. may not
2.arrive 不及物动词，意为“到达，抵达”。
后常接介词in 或 at，in 后接大地方，at后接小地方。arrive 后若是接地点副词，则不需要用介词。
例: When did you arrive in Shanghai 你什么时候到上海的
She arrives at the bus stop at 7 o'clock every morning,她每天早晨 7 点到达公共汽车站。
I arrive home at 5 o'clock in the afternoon every day. 我每天下午5 点到家。
辨析: arrive，reach 与 get to
arrive “到达”，为不及物动词，
reach 表示“到达(小地方)用 arrive at;“到达(大地方)用 arrive in
get to “到达”，为及物动词，后面直接跟宾语
3.Don’t listen to music in class. 不要再课堂上听音乐。
in class 固定短语， 意为“在上课，上课时”。
如： Don’t talk in class. Listen to the teacher. 不要讲话，注意听讲。
【class 的相关短语】
attend class 听课 after class 课后
the first class 一流，头等 have classes 上课
【辨析listen 与 hear】
listen 表示“积极地倾听”，而hear 则是“自然地听到”之意。如：
Listen to the teacher carefully. 请认真听老师的讲解。
Can you hear someone singing in the next room 你能听到有人在隔壁房间里唱歌吗？
listen 可用于祈使句，但表示“听到”的hear 却不可以。
Don’t listen to the radio in the meeting. 不要再会上听收音机。
listen 强调动作、过程，可用于进行时，但hear 表示“听到”的结果，不可用于进行时。如：
Be quiet, please! I’m listening to the music. 请安静，我在听音乐。
4.Can we bring music players to school？我们可以带音乐播放机到学校来吗？
bring…to的意思是“把……带来”；bring是及物动词，其动作的方向趋向于说话者。
【易混辨析】bring，take，carry与get
bring 带来，拿来，取来 从别处把某人或某物带到或拿到说话者所在的地点来。也可说成“由远及近”，有方向性。
take 带走，取走 把某物或某人从说话的地方带到另一个地方去，也可说成由近及远，有方向性。词意和bring相对，经常和介词to搭配。
carry 搬运 无方向性，多指搬重物。
get 去拿 来 从这边去别处，拿东西再回到这里。
(1)Please ____________ your homework here tomorrow.
(2)You must ____________ this book to your sister.She's at school.
(3)Would you please __________ this magazine (杂志) to the library
(4)Can you __________ me that glass
5.I have to keep my hair short. 我不得不留短发。
点拨：“keep +sb./sth.+形容词”表示“使某人或者某物保持某种状态”。此句式中的keep是动词，意为“保留，保存，保持”。
例如：Too much work keeps me busy and tired.太多的工作让我忙碌而且疲惫。拓展：keep的其他用法
1）“keep+形容词”，意为“保持某种状态”。例如：Keep quiet, please!请保持安静!
2）“keep sb. doing sth.”表示“让某人继续/不断地做某事”。例如：He kept me waiting for an hour.他让我等了一个小时。
