VisitPacificScienceCenter’sStore
Don’tforgettostopbyPacificScienceCenter’sStorewhileyouareheretopickupawonderfulscienceactivityorsouvenirtorememberyourvisit.Thestoreislocated(位于)upstairsinBuilding3rightnexttotheLaserDome.
21．WherecanyoubuyasouveniratPacificScienceCenter?
A．InBuilding1.
B．InBuilding3.
C．AttheLaserDome.
D．AttheDennyWayentrance.
答案B
解析细节理解题。首先根据题干中的“souvenir”可将答案锁定在VisitPacificScienceCenter’sStore这一部分；再根据本段中的“Thestoreislocated(位于)upstairsinBuilding3rightnexttotheLaserDome.”可知PacificScienceCenter的购物点在LaserDome旁边的3号楼上，故选B。
点津解答这类题时，一个常用的方法就是根据题干或选项中的线索词从原文中找到相关的句子。如该句中出现了but，however，yet，while等表转折的词语及inaddition，furthermore，besides，moreover，what’smore，mostofall，mostimportantly，especially等表递进的词语，后面往往为关键信息，是正确答案。但要与选项进行比较，最终确定答案。该方法运用的前提是在题干中找到定位关键词。该方法多用于细节理解题。
