Question

13．When it comes to getting older，humans aren't so special after all．It turns out their pattern of aging isn't too different from most other primates，such as chimps，monkeys and baboons，new research shows．
A team led by Anne Bronikowski of studied data on primate aging collected over decades around the world and compared it with statistics on modern Americans．Aging was defined as the increased risk of dying from natural causes while getting older．Some experts have thought that because people have relatively long life spans，humans aged differently from other mammals．
The research team believed that any major difference between humans and primates was most likely to show up with modern people，rather than a hunter-gatherer culture，Bronikowski said in a telephone interview．"And the fact that we don't find a difference there is more compelling．"
The basic pattern they found is a relatively high risk of dying in infancy （幼兒時(shí)期），a low risk of death during the juvenile years and then an increased risk of dying as aging progressed．Also，they found that in most cases males don't live as long as females．The authors wrote it in a study published online Thursday in the Journal Science．
The only exception to the general pattern was the muriqui monkey in Brazil； males and females have similar life spans．Unlike other primates，muriqui males do not compete with each other for access to females．Instead，they cooperate with each other，explained co-author Karen Strier，an anthropologist at the University of Wisconsin who has studied muriquis since 1982．The researchers said the reason males of other species die earlier than females may be a result of stress of competition．
Joseph W．Kemnits of the Wisconsin National Primate Research Ceter called the study"an important step"because it provides the first assessment of patterns of aging in large populations of nonhuman primates living in their natural environments．Kemnits was not part of the research team．
"The study of other primates contributes to understanding human aging because we share so much of our basic physiology，"added anthropology professor Kristen Hawkes of the，who was not part of the research team．

Answer 1

分析 本文主要講述人類和類人猿有類似的老化模式．

解答 ADCB
67   A  主旨大意題．  通讀全文可知本文主要講述人類和類人猿有類似的老化模式．故選A．
68   D  細(xì)節(jié)題． 根據(jù)文章第二 段A team led by Anne Bronikowski of studied data on primate aging collected over decades around the world and compared it with statistics on modern Americans． 可知Anne Bronikowski 是研究隊(duì)伍的領(lǐng)隊(duì)，故選D．
69   C   猜測詞義題．  根據(jù)文章第四 段The basic pattern they found is a relatively high risk of dying in infancy （幼兒時(shí)期），a low risk of death during the juvenile years and then an increased risk of dying as aging progressed． 可知研究的過程是從幼兒到青少年再到老年，故選C．
70  B  細(xì)節(jié)題． 根據(jù)文章最后一段The study of other primates contributes to understanding human aging because we share so much of our basic physiology 可知本文是一個(gè)關(guān)于人類和類人猿有類似的老化模式的研究，故選B．

點(diǎn)評 學(xué)生需要認(rèn)真閱讀原文，把握文章大意，對文章脈絡(luò)有整體的了解，能仔細(xì)查找文中細(xì)節(jié)，并能根據(jù)文章內(nèi)容進(jìn)行合理的推測判斷．
