發(fā)明

指經(jīng)過認識和實踐創(chuàng)造出前所未有的事物。Edisoninventedthelightbulb.愛迪生發(fā)明了電燈泡。

invention和inventor都是名詞,前者意為“發(fā)明”,后者意為“發(fā)明家”。discover,invent和find都是動詞,它們的詞義相近,但是有區(qū)別:

★discover意為“發(fā)現(xiàn)”,指發(fā)現(xiàn)某種本來存在,但以前未被發(fā)現(xiàn)或未為人所知的事物或現(xiàn)象。

Thelostbikewasdiscoveredatthebusstop.丟了的自行車在公共汽車站那兒找到了。

LaterIdiscoveredthathewassokind.后來我才發(fā)現(xiàn)他那么善良。

★invent意為“發(fā)明”,指發(fā)明以前不存在的東西。

Doyouknowwhoinventedthecomputer?

你知道誰發(fā)明的電腦嗎？

★find意為“找到,發(fā)現(xiàn)”,指偶然發(fā)現(xiàn)或幾乎沒有困難地發(fā)現(xiàn)。

Ifoundsomeoldphotosinthatdrawer.

我在那個抽屜里發(fā)現(xiàn)了一些舊照片。beusedfor...被用來……是由“usesth.forsth./doingsth.”結構轉變而來,介詞for在這里表示用途或作用,后面可以接名詞、代詞或動詞-ing形式。Thismachinecanbeusedforcuttinggrass.

這個機器可以被用來割草。★beusedas意為“被用作為……，被作為……使用”EnglishisusedasaforeignlanguageinChina.★beusedby意為“被……使用”Rubbersareusedbythestudentstocorrectmistakes.鏈接:★usedtodosth.意為“過去常常做某事”。IusedtosmokewhenIwasyoung.★usesth.todosth.意為“使用某物來做某事”,其被動結構為“sth.beusedtodosth.”。Theseknivesareusedtocutpies.
