Energy,effortandresponse【答案】（1）C（2）D（3）D（4）B【解析】【分析】本文是一篇說(shuō)明文，研究表明，老年人往往會(huì)記住生活中積極的事物，而不是消極的事物。十年前作者與生物學(xué)家羅伯特·特里弗斯合作研究身體是如何使用能量的，他們的發(fā)現(xiàn)解釋了這一現(xiàn)象。（1）考查推理判斷。根據(jù)第二段中的“Wehaveanenormousnumberofimmunecellscoursingthroughourbody,amomentarybreakfromproductionisfine.So,whenourbodyneedsextraenergy,oneoftheplacesitgoesisourimmunefunction.”可知我們的身體里有大量的免疫細(xì)胞，暫時(shí)停止運(yùn)作是可以的。因此，當(dāng)我們的身體需要額外的能量時(shí)，（我們的身體）會(huì)去找免疫系統(tǒng)。由此可以推斷，免疫系統(tǒng)會(huì)暫時(shí)停止來(lái)為身體提供額外的能量。選C。（2）考查詞義猜測(cè)。根據(jù)第三段中的"becomingmorefocusedonthepositivethingsinlifeinanefforttoenhancetheirimmunefunctioning."可知老人們更加關(guān)注生活中積極的事物，是為了增強(qiáng)他們的免疫功能。也就是說(shuō)積極與免疫功能之間有關(guān)系，越積極，免疫功能越強(qiáng)，就能活得越久，所有選項(xiàng)中D項(xiàng)（樂(lè)觀與壽命）之間最切題，故選D。（3）考查推理判斷。根據(jù)最后一段中的"Asaresult,ourimmunesystemevolvedtoruninmaximumamountswhenwe'rehappy,buttoslowdowndramaticallywhenwe'renot."可知當(dāng)我們快樂(lè)時(shí)，我們的免疫系統(tǒng)進(jìn)化到最大程度，但是當(dāng)我們不快樂(lè)時(shí)，免疫系統(tǒng)會(huì)減弱。由此推斷，消極會(huì)消耗我們身體的能量，降低對(duì)疾病的抵抗力。選D。（4）考查主旨大意。作者開(kāi)頭提出老年人更關(guān)注積極的事情，后文提到積極的情緒會(huì)增強(qiáng)免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關(guān)系，選B。【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷，詞義猜測(cè)和主旨大意三個(gè)題型的考查，是一篇科研類(lèi)閱讀，考生需要根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。7．閱讀理解Learning,FastandDeep
