高中关于would 和used to (be used to doing)的用法
以下是小编给大家整理的高中语法关于would 和used to (be used to doing)的用法，希望可以帮到大家
1) would 的用法
1.委婉地提出请求、建议(三个句型)
a.Would you ⋯? 表示客气的请求
与Will you ⋯? 同义，但Would you ⋯? 更客气一些。
would like 的用法
would like (=want) 作“愿⋯⋯、欲⋯⋯”解，表客气的请求。
①would like to +动词原形 想要(愿)做⋯⋯
I would like to go there. (我愿意去那里。)
②Would like +sb. + to + 动词原形 希望某人做⋯⋯
I would like you to do it again. (我希望你再做一次。)
③Would you like + 名词 ～? 邀约，表请客
Would you like some tea ? (喝点茶吧?)
④Would you like to + 动词原形? 邀约，表请客
Would you like to have a cup of tea ? (喝一杯茶吧?)
Would you (Will you) please be quiet ?
请您安静一下好吗?
(回答同Will you ⋯?参见P.172)
b.主语+would like to +V.⋯ 想要、愿意干⋯⋯
和want to do sth.相近，但比它要客气。
I would like to take a taxi.
=I want to take a taxi.
我想坐出租汽车。
c.Would you like sth.?
Would you like to do sth. ? 你愿意⋯⋯?
注意
①would like 后加动词时需加to：
would like to do sth.
②而Will you ⋯? Would you ⋯?后加动词则不能加to：
Will you do it?
Would you like coffee ?
你喝杯咖啡好吗?
Would you like to do morning exercises ?
你做早操好吗?
2.表示过去反复发生的动作
would 与used to sth.同义，都表示过去多次发生的习惯动作，但used to 表较有规则的习惯，would 较无规则。
In class he would ask some silly q uestions, and his classmates
would laugh at him.
课上，他总是问一些愚问题，他的同学们总是嘲笑他。
When I pass my school I would see my teachers who taught me
5 years ago.
我路过我母校时，我总是进去看看五年前教我的老师。
2 used to 的用法
1.used to +动词原形(表过去的习惯)
表过去(规则)的习惯或某时期的状况，但现今已不存在。
I used to drink tea.
我过去总是喝茶。
He used to smoke. (But now he never smokes.)
他过去抽烟。(现在不再抽烟了。)
When he was young he would smoke a lot.
他年轻时，他总是吸许多烟。(不含有和现在的比较，现在他也许
还在抽，也许不抽了。)
2.be used to sth. (doing sth.) 习惯于⋯⋯
get used to sth. (doing sth.) 对⋯⋯变习惯，习惯于⋯⋯
它们在形式上易与used to do 相混，但意思上和语法结构上有很大不同be (get)used to 中的to 是介词，所以后面可以跟名词、代词或动名词，而used to 后需跟动词不定式，to 是小品词。
Now he is / get used to fat meat.
=Now he is / get used to eating fat meat.
现在他已经习惯于吃肥肉了。
He used to eat fat meat.(But now he doesn’t eat it.)
他过去吃肥肉。(现在不吃了。)
He would eat fat meat when he was in the countryside.
他在农村时，他总是吃肥肉。
Li Ming was/got used to sitting up all right during the war.
战争期间，李明习惯于熬夜了。
比较
would 和 used to
used to do sth.含有与现在比较的意思，即过去常做，而现在不做了。而would 没有这一含义。
would 经常和表示过去时间的短语、从句一起连用，或通过上下文可以明确是过去的事。而used to 则不必。
Li Ming used to sit up all night ,and that was harmful to his
health.
李明过去总是熬夜(现在不熬夜了)，那样对他的身体非常有害。
Li Ming would sit up all night during the war.
战争期间，李明总是熬夜。(现在也许还是熬夜，也许不熬夜了。)
