辨析: get to/reach/arrive
相同点:都是“到达“的意思。
不同点:get to+地点;reach+地点。
arrive at+小地点(车站等);arrive in+大地点(国家等)
注意:get to与地点副词(here/there/home…)不用介词to
eg: i want to go to beijing.
i got home at 15:00.我下午三点到的家。
arrive是不及物动词,后面若接地点名词则要和in/at连用,接地点副词时则不用介词。
eg: i arrived home at 15:00. =i got home at 15:00.
reach是及物动词,后面直接接地点名词或副词。
eg: when will they reach here?
hear、listen和sound
都有"听"的意思,但三者是有区别的:
hear"听说" 侧重于"听"的内容。
eg:i'm sorry to hear that you are ill. 听说你生病了我很难过。
listen"听"侧重于"听"这一动作。
eg:listen to me carefully. 认真听我说。
sound"听起来" 它是系动词后面接形容词等。
eg:that sounds great. 那听起来真不错。
辨析take, bring
take“带走,拿走”指把东西从说话地带到别的地方。
eg: can you help me to take the books to the classroom?你能帮我把这些书带到教室里去吗?
bring“带来”指把东西从别处带到说话地。
eg: bring your homework here tomorrow, please.请你明天把作业带到这儿来。
be strict with sb “对某人严厉”
eg: mr. white is very strict with us. 怀特先生对我们要求很严格。
be strict in (doing) sth “对某事要求严格”
eg: our boss is strict in our work. 我们的老板对我们的工作要求严格。
help sb (to) do sth帮助某人做某事。
help sb with sth 帮助某人做某事。
eg: i often help him with his lessons.我常帮他学功课。
help oneself(myself/yourself/herself…) to+n.请随便用…
eg:please help yourselves to some fruit.请随便吃些水果。
help还可作名词,表示“帮助”,是不可数。
many, too much与much too
典型例题】i h**e __skirts and this one is __large for me, so you can take it if you like.
a. too many; too much b. too much; much too c. too many; much too
与also典型例题】

a. also b. too c. either d. to
be in bed "在床上、卧床",in 和bed之间不能用冠词,bed也不用复数。
eg: d**e has to be in bed early every night.大卫每晚必须很早睡觉。 .
no talking ! 禁止交谈。"no后面加上名词或动名词doing也表示不要做某事。
与don't +do的用法相似。
eg: no smoking! don't smoke here! 禁止吸烟
三、重点语法。
1h**e to:主语是第三人称单数时用has to,(过去时:无论人称和单复数都用had to.)
否定形式:主语+don't h**e to+动词原形+其他
一般现在时:主语是第三人称单数时用doesn't h**e to,其它时候用don't h**e to.
过去时: 无论人称和单复数都用didn't h**e to)
2.情态动词must的用法:
must表示说话人的主**法,及主观上的必要性,还用于命令或愿望。只用于现在时,无人称和单数的变化。
表示有很大把握的判断或者推测,意思是“一定,准是”。
eg: the tall man must be your father.那个高个子男人一定是你的爸爸。
以must开头的一般疑问句,它的否定回答用needn’t(不必要),不用mustn’t(不允许),mustn’t常用于否定句中表示“不允许,禁止”。
eg:--must i go there on foot?我必须得走过去吗?
---no, you needn’t.不,你不需要。
you mustn’t park your car here.你的车不允许停在这儿。
