18、why/who/where/when/how 等。that,whether 在同位语从句中不做成分，that 无实际意义，whether 表是否；其他连词具有实际意义，同时在同为语从句中做一定的成分。1.Thenewsthatourteamhadwonthechampionshipencouragedusallgreatly.2.Givemeyourpromisethatyouwillcometoourpartythisevening.3.Wehaveproofthatthemanisguilty.4.Ihavenoideawhyshequitherpresentjob.5.Thereisno
