onlyintheelderly”意為“它只發(fā)生在老年人身上”；選項(xiàng)B“Itinvolvesthebrain'sabilitytoreorganizeitself”意為“它涉及大腦重新組織自己的能力”；選項(xiàng)C“Itprimarilyaffectsthevisualcortex”意為“它主要影響視覺(jué)皮層”；選項(xiàng)D“Itisatemporaryphenomenon”意為“它是一種暫時(shí)現(xiàn)象”。只有選項(xiàng)B與原文意思一致，故選B。7.解析思路：根據(jù)第三段第三句“Theword'resilience'inthethirdparagraphisclosestinmeaningto______”中的“phenomenon”意為“現(xiàn)象”。選項(xiàng)A“condition”意為“條件”；選項(xiàng)B“process”意為“過(guò)程”；選項(xiàng)C“disease”意為“疾病”；選項(xiàng)D“event”意為“事件”。這里指神經(jīng)可塑性這一現(xiàn)象，故“event”意思最接近，故選D。8.解析思路：根據(jù)最后一段第一句“Understandinghowthebrainprocessesinformationandadaptsisessentialfordevelopingeffectivetreatmentsforneurologicaldisorders”可知，理解大腦如何處理信息和適應(yīng)對(duì)于開(kāi)發(fā)有效的神經(jīng)系統(tǒng)疾病治療方法至關(guān)重要。選項(xiàng)A“improvedathleticperformance”意為“提高運(yùn)動(dòng)表現(xiàn)”；選項(xiàng)B“enhancedcognitivehealth”意為“增強(qiáng)認(rèn)知健康”；選項(xiàng)C“bettertelevisionprogramming”意為“更好的電視節(jié)目”；選項(xiàng)D“increasedmemoryloss”意為“增加記憶喪失”。只有選項(xiàng)B與原文意思一致，故選B。9.解析思路：根據(jù)最
