3、d,wonderful,funny,possible,likely,certain,probable,important,necessaryetc.)+that从句。如：Itiscertainthatshewilldowellinherexam.Itisprobablethathetoldhereverything.Itisimportantthatweshouldreadmoreandmore.b.It+be+名词词组(nowonder,anhonour,agoodthing,apity,nosurprise,etc.)+that从句。如：It’sapitythatwecan’tgo.
