词汇点睛句型透视Unit4语法课件语法点击usedto的用法

usedto表示“过去常常；以前常常”，用于描述过去经常发生的动作或存在的状态。usedto后跟动词原形。关于usedto的用法，有以下三个考点：考点1：含有usedto的句型肯定句：I/You/We/They/He/She/Itusedto＋do否定句：I/You/We/They/He/She/Itdidn'tuseto＋do一般疑问句及其回答：—Didyou/we/they/he/she/ituseto＋do?—Yes,…did./No,…didn't.特殊疑问句：疑问词＋did＋主语＋usetodo…？如：IusedtobeshortwhenIwasyoung.

我小时候个子矮。Ididn'tusetowalktoschool.我过去不常走路上学。—Didyouusetohavestraighthair?

你过去是直发吗？—Yes,Idid.

是的，我是。Wheredidyouusetolivebeforeyoucamehere?你来这儿之前住在哪儿？考点2:含有usedto的反意疑问句，附加疑问部分用“didn't＋主语”。如：Heusedtowearglasses,didn'the?

他过去戴眼镜，不是吗？考点3：usedtodo与beusedtodoing

usedtodo表示“过去常常”，usedto后面必须跟动词原形，而beusedto

是“习惯于”，表示某一客观事实或状态，不强调动作，to是介词，后面接名词或动名词。get/becomeusedto指从不习惯到习惯这一过程的转变。另外，它往往包含着克服困难去适应的意思。如：Iamusedtotheweatherhere.

我已经习惯这里的天气了。Youwillsoongetusedtotheweatherhere.

你不久就会适应这里的天气。实战演练(
