C.thatD.where【解析】由句式结构可以判断thepartyistobeheld是getanyidea的同位语，故空格处应为同位语从句的引导词，且该从句中句子成分完整，但语意不完整，故应选择D项，表示地点。reasonforherpreferenceforcitylifeisshecanhaveeasyaccesstoplaceslikeshopsandrestaurants.（2023上海）A.thatB.howC.whatD.why【解析】答案选A。因为本题考查考that引导同位语从句的用法。此处that不可以省略。句子的正常语序应当是：Onereasonthatshecanhaveeasyaccesstoplaceslikeshopsandrestaurantsisforherpreferenceforcitylifenews________（房价将要下跌）hascausedmanypeopletoselltheirhousesatlowerprices.(fall)（2023湖北）【解析】答案：thatthehousingpricewillfallsciencehasgivenclearevidence______smokingcanleadtomanydiseases.（2023•天津卷）A.whatB.whichC.thatD.where【解析】从句说明名词evidence，此处that不可以省略。故选C。5.Whenthenewscamethewarbrokeout,hedecided,toserveinthearmy.（2023•辽宁卷）A.sinceB.whichC.thatD.because【解析】从句说明名词thenews，此处that不可以省略。故选C。6.Thefacthasworriedmanyscientists______theearthisbecomingwarmerandwarmertheseyears.(09江西)A.whatB.whichC.thatD.though【解析】答案C。本题考查间隔式同位语从句的用法。即先行词是thefact和that引导的同位语从句中间隔了谓语部分。camefromtheschooloffice________WangLinhadbeenadmittedtoBeijing【解析】答案C。解析同上题。8.－Isthereanypossibility______youcouldpickmeupattheairport?(09浙江)－No.WhenB.that
