ry在這里意為“有意識(shí)的”，與句意相符。C)conscious“有意識(shí)的”與句意相符；A)involuntary“無意識(shí)的”；B)controlled“受控制的”；D)unconscious“無意識(shí)的”都與句意不符。11.A解析：通讀全文，文章主要介紹了大腦的功能，包括控制身體活動(dòng)、處理信息、做決策、思考、記憶、想象力等。因此，A)thefunctionsofthebrain“大腦的功能”是正確答案。12.C解析：根據(jù)第三段，左半球通常被認(rèn)為負(fù)責(zé)語言。因此，C)Thelefthemisphere“左半球”是正確答案。13.B解析：根據(jù)文章內(nèi)容，大腦的功能包括控制呼吸（A）、分析數(shù)據(jù)（B，屬于認(rèn)知功能）、維持平衡（C）、做決策（D）。因此，B)Analyzingdata“分析數(shù)據(jù)”不是大腦的功能。14.A解析：根據(jù)第三段，hemispheres在這里指大腦皮層的左右兩個(gè)半球。因此，A)twopartsofthecerebrum“大腦皮層的兩個(gè)部分”是正確答案。15.B解析：根據(jù)第三段，胼胝體連接兩個(gè)半球。因此，B)connectsthetwohemispheres“連接兩個(gè)半球”是正確答案。16.A解析：根據(jù)第四段，posture在這里意為“姿勢(shì)”，與句意相符。A)position“姿勢(shì)”與句意相符；B)balance“平衡”；C)movement“運(yùn)動(dòng)”；D)coordination“協(xié)調(diào)”都不準(zhǔn)確。17.D解析：根據(jù)第五段，大腦被顱骨保護(hù)，被腦膜包圍，浸泡在腦脊液中。因此，D)alloftheabove“以上都是”是正確答案。18.A解析：根據(jù)第四段，大腦皮層負(fù)責(zé)高級(jí)認(rèn)知功能。因此，A)highercognitivefunctions“高級(jí)認(rèn)知功能”是正確答案。19.A解析：根據(jù)第四段，coordinates在這里意為“協(xié)調(diào)”，與句意相符。A)controls“控制”與句意相符；B)combines“結(jié)合”；C)allows“允許”；D)memorizes“記憶”都不準(zhǔn)確。20.A解析：根據(jù)第一段最后一句，大腦是思想、情感、記憶和想象力的中心。因此，A)thebrainisthecenterofthoughtandemotion“大腦是思想和情感的中心”是正確答案。PartIIGrammarCloze1.A解析：advertisements是名詞，這里需要一個(gè)形容詞修飾它，advertised意為“被廣告的”，符合句意。2.opportunity解析：這里需要一個(gè)名詞作賓語，opportunity意為“機(jī)會(huì)”，符合句意。3.molecularbiology解析：這里需要一個(gè)名詞短語作賓語，molecularbiology意為“分子生物學(xué)”，符合句意。4.geneticengineering解析：這里需要一個(gè)名詞短語作賓語，geneticengineering意為“基因工程”，符合句意。5.keen解析：這里需要一個(gè)形容詞作表語，keen意為“熱切
