完成做某事。IfinishedwritingtheEnglishcomposition.【巧学妙记】

常接动词-ing作宾语的词（短语）喜欢（enjoy）错过（miss）别介意（mind）,完成（finish）愉快（havefun）勤练习（practice）,忙得（bebusy）禁不住（can'thelp）想放弃（giveup）。注意:介词后一般接动词-ing形式。WhataboutwatchingTV?2.Andshewon'tbehappyifsheseesthismess.messn.杂乱；不整洁—Don'tmakeamessonthebalcony,Betty. —Sorry,Iwon't.Alltheroomsareinamess.makeamess搞得一团糟（表示动作）beinamess杂乱不堪；陷入困境（表示状态）Whatamess!多么凌乱啊！【拓展延伸】

mess还可作动词，意为“使不整洁；弄脏；弄乱”。messup搞砸;弄糟messyadj.凌乱的；杂乱的I'veputthebooksaway.Pleasedon'tmessthemupagain.3.IthinktwohoursofTVisenoughforyou!此处，twohoursofTV虽为复数，但却表达一种整体的观念。英语语法规定，当时间、长度、距离或其他可数名词表示一个完整的整体概念作主语时，其后的谓语动词用其单数形式。e.g.Twomonthsisquitealongtime.两个月是挺长的一段时间。e.g.Thirtystudentsisnotabignumberforaclass.30人对一个班来说算不上是大数目。4.anyminutenow一种常见的口语表达法，相当于“随时；马上；在任何时刻”的意思，表示事情有可能在极短的时间内发生或眼下就要发生。minute还可以用second,moment,time等词替换。e.g.Don’tworry.Hewillcomehereanyminutenow.别担心,他会马上来这儿。Theguestsarearrivinganytimenowbutwe’restillnotready.

客人即刻就到，但我们还没有准备好。We’reexpectingthemanymomentnow.我们期待他们随时到来。初中英语人教版八年级下册Unit3
