1、Thatwecan’tgotoseethemovieontheweekendisapity.2、Thathismemorywasbecomingworseworriedhimalot.Itisapitythatwecan’tgotoseethemovieontheweekend.Itworriedhimalotthathismemorywasbecomingworse.用it作形式主語來改寫下面的句子

改錯1、Thatiswidelybelievedthatsmokingcancausecancer.2、Itissuggestedthatwewillholdameetingnextweek.It〔作形式主語〕解析：過去分詞如果是suggested,ordered,requested等表示建議，命令，請求等的詞時，主語從句應(yīng)用虛擬語氣，即“(should)+動詞原形”(should)hold四、主語從句中應(yīng)注意的問題1、從句的語序要用陳述句的語序。e.g.remainsamystery.他為什么做那件事依然是個謎。Whyhedidit2、從句做主語時，主句謂語動詞的單復(fù)數(shù)①單個主語從句做主語時，謂語動詞用單數(shù)e.g.Whenweshallhaveoursportsmeeting

notbeendecidedyet.②由兩個或多個連接詞引導(dǎo)一個主語從句時，謂語動詞也用單數(shù)

e.g.Whenandwhereweshallhaveoursportsmeetingnotbeendecidedyet.

has

has

③如果用and連接兩個或兩個以上的主語從句做主語時，謂語動詞用復(fù)數(shù)

e.g.Whentheywillstartandwheretheywillgonotbeendecidedyet.have

注意what和who引導(dǎo)主語從句時，主句謂語的數(shù)應(yīng)與主句中作表語的名詞保持一致。WhatIneed______money.WhatIneed______books.isareWhoyouwillgowith______Lucy.Whoyouwillgowith______thetwins.isare
