①If you go to some subway stations in Beijing now,you may see little footprints on the escalators. They tell riders:Instead of standing on one side,they can stand side by side.
②For years,standing on the right and walking on the left has been a rule for escalator riders. They think it is a good habit and helps everyone to go faster. However,there are problems behind it.
③Standing on one side is harmful to the escalators. The right side becomes ▲ while the left side stays light. Over time,the escalators may lean. Also,it can’t really make everyone go faster. Studies show that when people stand on one side,the escalator can carry about 80 people every minute. But when everyone stands side by side,the escalator can carry over 100 people!
④Most importantly,walking on an escalator is dangerous. Escalator steps are high. People can fall and get hurt easily.
⑤So,what is the best way to take escalators? Just hold on and stand still on both sides.

解析

【分析】
这是一篇结合时事热点的说明文类阅读理解题,解题时可以按照先读题干划出关键信息,再回原文定位对应内容的思路逐步推进:
1. 第1题要找现在北京部分地铁站扶梯能看到的标识图,直接定位第一段内容,明确标识的作用是提示乘客不用站单侧、可以并排站立,就能匹配正确选项。
2. 第2题是词义猜测题,定位第三段空格后的对比表述“stays light”,找到和“重量轻”反义的词汇即可得出答案。
3. 第3题是主旨目的题,通读全文梳理内容逻辑:开头引出扶梯新标识,中间分析过去“右站左行”旧规则的诸多弊端,最后给出正确的乘梯方式,就能匹配出作者的写作意图。
4. 第4题是语篇结构题,逐段概括段意后划分逻辑层次:第1段引入新现象,第2-4段先点明旧规则有问题,再展开讲两个具体弊端,最后第5段总结给出最优乘梯方式,就能选出对应结构。
【解析】
1. 细节理解题:根据原文第①段“you may see little footprints on the escalators. They tell riders:Instead of standing on one side,they can stand side by side.”可知,现在北京部分地铁站扶梯的脚印标识提示乘客两侧都可站立、并排站,对应两侧都有站立脚印标识的B选项,故选B。
2. 词义猜测题:空格后用while表对比,说明空格处词汇和后文的light(重量轻的)是反义关系,所有人都站在扶梯右侧,因此右侧承载的重量更重,heavy表示“重的”完全符合语境,故选D。
3. 主旨大意题:全文先引出北京地铁站扶梯的新标识,接着分析沿用多年的“右站左行”乘梯习惯存在损伤扶梯、运力低、易摔倒的诸多问题,最后点明正确的乘梯方式是两侧站好扶稳,因此作者的写作目的是解释正确的乘梯方式,故选C。
4. 语篇结构题:第①段总起,引入北京地铁站扶梯新标识的话题;第②段先点出过去的“右站左行”规则背后存在问题,第③段讲该习惯损伤扶梯、运力不足的问题,第④段讲该习惯的安全隐患,②③④共同属于分析旧规则弊端的中间论述部分;第⑤段总结给出最优乘梯方式,因此结构是①—②③④—⑤,对应选项C,故选C。
【答案】
1. B 2. D 3. C 4. C
