詞匯點睛句型透視Unit4語法課件語法點擊usedto的用法

usedto表示“過去常常；以前常常”，用于描述過去經常發生的動作或存在的狀態。usedto后跟動詞原形。關于usedto的用法，有以下三個考點：考點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一般疑問句及其回答：—Didyou/we/they/he/she/ituseto＋do?—Yes,…did./No,…didn't.特殊疑問句：疑問詞＋did＋主語＋usetodo…？如：IusedtobeshortwhenIwasyoung.

我小時候個子矮。Ididn'tusetowalktoschool.我過去不常走路上學。—Didyouusetohavestraighthair?

你過去是直發嗎？—Yes,Idid.

是的，我是。Wheredidyouusetolivebeforeyoucamehere?你來這兒之前住在哪兒？考點2:含有usedto的反意疑問句，附加疑問部分用“didn't＋主語”。如：Heusedtowearglasses,didn'the?

他過去戴眼鏡，不是嗎？考點3：usedtodo與beusedtodoing

usedtodo表示“過去常常”，usedto后面必須跟動詞原形，而beusedto

是“習慣于”，表示某一客觀事實或狀態，不強調動作，to是介詞，后面接名詞或動名詞。get/becomeusedto指從不習慣到習慣這一過程的轉變。另外，它往往包含著克服困難去適應的意思。如：Iamusedtotheweatherhere.

我已經習慣這里的天氣了。Youwillsoongetusedtotheweatherhere.

你不久就會適應這里的天氣。實戰演練(
