本單元的主人公used to似乎很懷舊，一出口就是“過(guò)去常?！?，具有鮮明的時(shí)態(tài)特點(diǎn)，讓我們近距離一一道來(lái)：

1. “主語(yǔ)+used to+動(dòng)詞原形+其它”。在這個(gè)句型結(jié)構(gòu)中used to的含義為“過(guò)去常常”。表示過(guò)去的習(xí)慣，暗示現(xiàn)在已無(wú)此習(xí)慣，請(qǐng)看圖：

Bill在過(guò)去幾年中一直在一家factory中工作，但現(xiàn)在他在supermarket中工作，所以Bill used to work in a factory. 隱含的意思是：Bill worked in a factory before but he doesnt work there now.

2. 我們可以說(shuō)I used to work.../She used to have.../they used to be...等等，也就是說(shuō)used這個(gè)詞沒(méi)有人稱的變化，to后面接動(dòng)詞原形。

請(qǐng)看例句：

·Lily has got short hair now but it used to be very long. 麗莉現(xiàn)在梳短發(fā)，但以前她是長(zhǎng)發(fā)。

注意：

①used to的否定形式是I didnt use to ....

·When I was a child, I didnt use to like tomatoes. 當(dāng)我還是個(gè)孩子時(shí)，我不喜歡吃西紅柿。

②問(wèn)句形式是Did ... use to ...?

·Did you use to be a teacher? 你過(guò)去是老師嗎？

3. used to這個(gè)詞組只用于講述過(guò)去，我們不能用use to來(lái)講述現(xiàn)在。

·I used to play tennis. These days I play golf. （不說(shuō)I use to play golf.）

·We usually get up early.（不說(shuō)We use to get up early）

詞語(yǔ)辨析：

1. used to和would

①used to和would都可表示過(guò)去的習(xí)慣或行為，常可換用。

When we were children we used to/would go skating every winter. 我們小時(shí)候每年冬天都去滑冰。

②used to含有較強(qiáng)的“今昔對(duì)比”的含義，而would無(wú)此含義。

I do not swim so often as I used to.我不像過(guò)去那樣常游泳了。（不能用would代替）

He would sometimes work into the night. 以前他常工作到深夜。（不表示現(xiàn)在他不工作到深夜）

③用would時(shí)，有時(shí)應(yīng)有時(shí)間狀語(yǔ)來(lái)加以限制，而used to則可無(wú)時(shí)間狀語(yǔ)。

He would go to see Mother every vacation. （那時(shí)）他每個(gè)假期都去看望媽媽。

He isnt what he used to be. 他不再是過(guò)去的他了。

2. used to do和be used to doing.

①be used to 是“習(xí)慣于”某一客觀事實(shí)和狀態(tài)，不強(qiáng)調(diào)動(dòng)作，to是介詞，后面接名詞或動(dòng)名詞。

He is used to hard work. 他習(xí)慣于艱苦的工作。

②get（或become）used to指的是從不習(xí)慣到習(xí)慣這一過(guò)程的轉(zhuǎn)變，另外，它往往包含著克服困難去適應(yīng)的意思。

You will soon get used to the weather here. 你很快就會(huì)習(xí)慣這里的天氣的。
