It39。s true that those with high status, from world leaders and prize winners to athletes and movie stars, are people we like and respect. A recent study published in Nature Human Behaviour showed that we seem to have an innate (天生的) preference for highranking peoples—but only if those people aren39。t hurtful toward others. Researchers showed toddlers (aged 21 to 31 months) a scene where two puppets (木偶) approached one another from opposite sides of a stage and one bowed to let the other pass first. Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three. However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, When approaching others, very young children care not only who wins, but also how. The previous experiment has shown that toddlers know about social status, but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference. In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others. So, when my fouryearold thinks that he has to get his shoes on first, I39。ll keep reminding him that helping his brother so they both finish faster is what winning is all about.（1）What do we tend to do according to the first paragraph? challenges all the time. highranking people. advantage of high status. others with offensive words.（2）Why did toddlers prefer the puppet allowed to pass? looked adorable. behaved smartly. seemed polite. was respected.（3）What can we infer from the latter study? people are better loved by toddlers. naturally dislike unkind behavior. care little about high social status. helpful contributes to being supported.（4）What should we do when we encourage children to win? them to use proper and creative ways. them to be as hardworking as possible. them to be considerate to other people. them to try to cooperate with someone else.【答案】 （1）B（2）D（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了人們更傾向于喜歡和尊敬地位高而又無害于他人的人，這似乎是一種天性，即使是蹣跚學步的孩子也是如此。 （1）考查細節(jié)理解。根據(jù)第一段中的“A recent study published in Nature Human Behaviour showed that we seem to have an innate（天生的）preference for highranking peoples—but only if those people aren39。t hurtful toward others.”可知，我們更傾向于敬佩那些地位高的人。故選B。 （2）考查細節(jié)理解。根據(jù)第二段中的“Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.”可知，蹣跚學步的孩子喜歡那個被允許通過的木偶，是因為這種行為代表著受人尊敬，孩子們更喜歡受尊敬的人。故選D。 （3）考查推理判斷。根據(jù)第三段中的“In this case, 18 of the 21 toddlers reached for the one who was knocked the participants were so young, this might even be an innate human preference.”可知，孩子們會走向被撞倒的人，而由于孩子太小，甚至可能是人類與生俱來的偏好。由此可推斷出，人們天生不喜歡不友善的行為。故選B。 （4）考查推理判斷。根據(jù)最后一段中的“In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others.”可知，孩子欣賞那些在做好事的同時表現(xiàn)出色的人。由此可推斷出，我們鼓勵孩子去贏的同時，提醒他們要體諒他人。故選C。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科教類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。5．犇犇閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 When you think back to the blackboard from your school days, what color is it? Chances are that it39。s green. So what39。s up with the name? Originally, blackboards were really black. Before wallsized blackboards existed, late 18thcentury students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones. In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn39。t draw the maps their teacher wanted on their tiny boards, so Pillans pu
