A new study has found that most threeyearolds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly. Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings. The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adultlike in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later. The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 72 percent. However, the amount of information eightto nineyearold children could recall dropped to 35 and 36 percent.（1）What does the new study tell us? memories decline with years. kids are the cleverest. memories can fade easily. adults cannot recall past events.（2）What does the underlined word persist in Paragraph 2 mean? ....（3）What can we learn from Paragraph 4? cannot have clear memories of past events. can think like adults when they get older. under 7 years old have different ways of forming memories. often forget things because they have no idea of time or place.（4）In the second session, nineyearold children _________. to discuss the same events all their family outings recall 72 percent of their past events remembered a small part of their past events【答案】 （1）A（2）B（3）D（4）D 【解析】【分析】本文是一篇說明文，介紹了記憶消失的一些知識。大多數(shù)三歲的孩子都能回憶起一年前發(fā)生在他們身上的許多事情，這些記憶在五歲和六歲時依然存在，但到七歲以上時，這些記憶會迅速衰退。在七歲之前，孩子們在記憶中沒有時間感和位置感。在5到7歲之間，孩子們能回憶起的記憶量保持在63%到72%之間。然而，8至9歲兒童能夠回憶起的信息量下降到35%和36%。 （1）考查細(xì)節(jié)理解。根據(jù)第二段“A new study has found that most threeyearolds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly.”一項新的研究發(fā)現(xiàn)，大多數(shù)三歲的孩子都能回憶起一年前發(fā)生在他們身上的許多事情，這些記憶在他們五歲和六歲時仍然存在，但當(dāng)他們超過七歲時，這些記憶迅速衰退?？芍卵芯扛嬖V了我們童年時的記憶隨年齡而衰退。 故選A。 （2）考查詞義猜測。根據(jù)第二段中的“but by the time they are over seven, these memories decline(衰退) rapidly.”到七歲以上時，這些記憶會迅速衰退，可知這些記憶在五歲和六歲時依然存在，故劃線單詞persist的意思是：存在，保留。故選B。 （3）考查推理判斷。根據(jù)第四段中的“They say that before the age of seven children do not have a sense of time and place in their memories.”他們說在七歲之前，孩子們在記憶中沒有時間感和位置感。可知孩子們經(jīng)常忘記事情，因為他們沒有時間感位置感，故選D。 （4）考查推理判斷。根據(jù)最后一段中的“ However, the amount of information eightto nineyearold children could recall dropped to 35 and 36 percent.”然而，8至9歲兒童能夠回憶起的信息量下降到35%和36%?？芍诘诙A段，九歲的孩子只記得他們過去的一小部分事情。故選D。 【點評】本題考點涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案。8．閱讀理解 By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (嬰兒) for longer periods than their contemporary relatives. The results, published in the journal Science Advances, provide a first insight into the practice of weaning (斷奶)that remain otherwise unseen in the fossil record. The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素）in the tooth enamel(牙釉質(zhì)), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血統(tǒng)), such as the brain development. In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life. These differences in nursing behaviors likely e with major changes in t
