8.ThisgavehimtheideathattheChineseperhapsfirstdiscoveredAmerica.
(二)同位语从句在名词idea;fact;news;thought;suggestion/advice;problem;proof等词后面带上that+陈述句这部分从句解释了前面的那些名词所指的内容，与那些名词起着同等作用的句子成分，叫同位语从句。

2.TheideathatEnglandstandsforFish&Chips,Speakers’Corner,BigBenandtheTowerofLondonispast.
3.TheresultthatOxfordbeatCambridgebyafootin2003surprisedmany.

6.Iaskedmyselfaquestionwhethertheresearchisworththetrouble.
7.Ihavenoideawhathashappenedtohim.
(三)同位语从句与定语从句的辨析：
that引导的同位语从句解释前面名词的内容，that是连词没有任何意义，在从句中不做任何成分。而定语从句修饰前面的先行词，从句有关系词that;which;who;when;where;why引导，先行词在从句中充当主语，宾语，状语。
1.Thenewsthattheplanewouldtakeoffontimemadeeveryonehappy.
2.Thenewsthatisspreadingaroundtheairportisthataheavystormiscoming.
(四)what;whatever;whoever;where引导的名词性从句：what+陈述句：……的话/事/的样子;whatever+陈述句：……的任何东西;whoever+陈述句：做…事的任何人;(以上名词性从句做主语，表语或宾语);where+陈述句：……的所在，做表语。
1.Whatlifewillbelikeinthefutureisdifficulttopredict.
