C.thatD.where【解析】由句式結(jié)構(gòu)可以判斷thepartyistobeheld是getanyidea的同位語，故空格處應(yīng)為同位語從句的引導(dǎo)詞，且該從句中句子成分完整，但語意不完整，故應(yīng)選擇D項，表示地點。reasonforherpreferenceforcitylifeisshecanhaveeasyaccesstoplaceslikeshopsandrestaurants.（2023上海）A.thatB.howC.whatD.why【解析】答案選A。因為本題考查考that引導(dǎo)同位語從句的用法。此處that不可以省略。句子的正常語序應(yīng)當是：Onereasonthatshecanhaveeasyaccesstoplaceslikeshopsandrestaurantsisforherpreferenceforcitylifenews________（房價將要下跌）hascausedmanypeopletoselltheirhousesatlowerprices.(fall)（2023湖北）【解析】答案：thatthehousingpricewillfallsciencehasgivenclearevidence______smokingcanleadtomanydiseases.（2023?天津卷）A.whatB.whichC.thatD.where【解析】從句說明名詞evidence，此處that不可以省略。故選C。5.Whenthenewscamethewarbrokeout,hedecided,toserveinthearmy.（2023?遼寧卷）A.sinceB.whichC.thatD.because【解析】從句說明名詞thenews，此處that不可以省略。故選C。6.Thefacthasworriedmanyscientists______theearthisbecomingwarmerandwarmertheseyears.(09江西)A.whatB.whichC.thatD.though【解析】答案C。本題考查間隔式同位語從句的用法。即先行詞是thefact和that引導(dǎo)的同位語從句中間隔了謂語部分。camefromtheschooloffice________WangLinhadbeenadmittedtoBeijing【解析】答案C。解析同上題。8.－Isthereanypossibility______youcouldpickmeupattheairport?(09浙江)－No.WhenB.that
