Unit 4 Where’s my backpack?. 教案、备课


(学案)Unit 4 Where’s my backpack?

知识准备

你知道英语中的字母能构成习语吗?

1. as easy as ABC:极其容易

  ABC原指儿童拼词识字的课本,现在多用来表示某一方面的基础知识。说某事as easy as ABC就是说此事很容易。

2. from A to Z:从头到尾;彻底地

  此语主要用于口语,Z来源于izzard。Izzard是英语中最后一个字母Z的方言变体。

3. U and non-U:上层阶级和非上层阶级

  据说,此语是一位名叫Alan Ross的英国社会学教授杜撰的。他认为衣着、外表都不足以把上层阶级与中层阶级的人区分开,只有他们的语言才能表现其明显的特点。U表示上层阶级(upper-class),non-U表示非上层阶级(non-upper-class)。

4. L driver:见习汽车司机

  字母L为learner的首字母。在英国,见习司机的汽车牌照上标有L字样。

5. the big C:癌症

  字母C为cancer的首字母。此语为委婉语,多见于口语。

6.get the big E:被解雇

  此语为get the big elbow的委婉说法。E是elbow(肘)的首字母。

7. the big H:海洛因

  此习语多见于美国口语,H为heroin的首字母。

8. on the q.t.:悄悄地;秘密地

此习语相当于on the quiet,q和t为quiet的首、尾字母。它产生于19世纪的民谣中。
