刘传增回答:
78.hasmopped.考查现在完成时.根据英语提示,特别是"thefloor"(地板)和"tidy"(干净),确定选用mop的某种形式.mopthefloor拖地板.根据下文"Itlookssotidynow"所说,现在地板很干净,所以,是有人已经拖过了,故时态用现在完成时,即"have/has+过去分词"形式.主语为第三人称单数who,助动词选用has;mop的过去分词为mopped.故填hasmopped.
79.wasintroducing.考查过去进行时.根据英语提示,特别是"mynewteachertomyparents",确定选用introduce的某种形式.introducesbtosb把某人介绍给某人;introducemynewteachertomyparents把新老师介绍给我父母.根据上文,事情发生在过去,要用过去的某种时态.对方打电话时"我"正在向父母介绍新老师,所以没有听到他的电话,故用过去进行时,即"were/was+现在分词"形式.主语为第一人称I,助动词变为was;introduce的现在分词为introducing.故填wasintroducing.
80.isdiscussing.考查现在进行时.根据英语提示,特别是介词"with",确定选用discuss的某种形式.discusssthwithsb和某人讨论某事;discusshisfavouriteTVshowwithhisfriends和朋友一起谈论他最喜欢的电视剧.对话发生时,父亲正和朋友讨论,故用现在进行时,即"are/is/am+现在分词"形式.主语为第三人称单数he,助动词用is;discuss的现在分词为discussing.故填isdiscussing.
81.willattend/aregoingtoattend.考查一般将来时.根据英语提示,特别是"theconcert"(音乐会),确定选用attend的某种形式.attend为动词,意思是参加.attendtheconcern参加音乐会.根据时间状语"intwoweeks"(两周后),确定使用一般将来时,即"will(begoingto)+动词原形"形式,也就是willattend或aregoingtoattend(主语为复数,助动词be变为are).故填willattend/aregoingtoattend.
82.built.考查一般过去时.根据英语提示,特别是amodel(一个模型),确定选用build的某种形式.buildamodel建造一个模型.根据下文"leftfor"的时态,该动作发生在过去,且两个动作一前一后,依次进行,故用一般过去时.build的过去式为built.故填built.
83.mixes.考查一般现在时.根据英语提示,特别是介词"with"确定选用mix的某种形式.mixsthwithsth用(把)…和…混合在一起.mixsaltwithsugar把食盐和蔗糖混合在一起.本句说明的是汤姆的一贯做法,故用一般现在时.主语为第三人称单数Tom,动词mix要变为第三人称单数形式mixes.故填mixes
