1、Thatwecan’tgotoseethemovieontheweekendisapity.2、Thathismemorywasbecomingworseworriedhimalot.Itisapitythatwecan’tgotoseethemovieontheweekend.Itworriedhimalotthathismemorywasbecomingworse.用it作形式主语来改写下面的句子

改错1、Thatiswidelybelievedthatsmokingcancausecancer.2、Itissuggestedthatwewillholdameetingnextweek.It〔作形式主语〕解析：过去分词如果是suggested,ordered,requested等表示建议，命令，请求等的词时，主语从句应用虚拟语气，即“(should)+动词原形”(should)hold四、主语从句中应注意的问题1、从句的语序要用陈述句的语序。e.g.remainsamystery.他为什么做那件事依然是个谜。Whyhedidit2、从句做主语时，主句谓语动词的单复数①单个主语从句做主语时，谓语动词用单数e.g.Whenweshallhaveoursportsmeeting

notbeendecidedyet.②由两个或多个连接词引导一个主语从句时，谓语动词也用单数

e.g.Whenandwhereweshallhaveoursportsmeetingnotbeendecidedyet.

has

has

③如果用and连接两个或两个以上的主语从句做主语时，谓语动词用复数

e.g.Whentheywillstartandwheretheywillgonotbeendecidedyet.have

注意what和who引导主语从句时，主句谓语的数应与主句中作表语的名词保持一致。WhatIneed______money.WhatIneed______books.isareWhoyouwillgowith______Lucy.Whoyouwillgowith______thetwins.isare
