【正文】 d 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. 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. 【點評】本題考點涉及細節(jié)理解題型的考查，是一篇介紹類閱讀，考生需要準確捕捉細節(jié)信息，并結(jié)合題目要求，從而選出正確答案?？芍撬蚴鼓峥ǔ蔀榉侵拮蠲利惖墓珗@之一。 （3）考查細節(jié)理解。分析選項可知看粉紅色湖泊的最佳時間是一月份。根據(jù)第三段中的”The best times to see the lake at its pinkest is during Senegal39。故選B。根據(jù)第二段中的”The foot of the Merzouga Dunes is the best location for gazing at stars, totally free of light pollution.“默佐加沙丘的腳下是觀星的最佳地點，完全沒有光污染。Sports.【答案】 （1）B（2）D（3）C 【解析】【分析】本文是一篇應(yīng)用文，介紹了四個非洲最神奇的地方。C.Animals.January.（3）What makes Nyika one of the most beautiful parks in Africa?
