题干

樱桃在还没成熟时,它们味道很酸,成熟后樱桃的含糖量提高了,吃起来也就可口了。专门种植樱桃的农户到了收获时节才采摘樱桃,所以超市里的樱桃都是到了成熟期才上架的。然而,生长在公园里的樱桃,却总是在尚未成熟、味道太酸的时候就被人摘下来了。如果人们能等久点再采摘,樱桃的味道会更好。可人们为什么有的等得有的等不得呢?从经济生活的角度,最合理的解释是(   )。

A:公园里的樱桃有更高的品质

B:不同的所有制影响着人们对财产的处置方式

C:不同的消费理念导致了不同的消费行为

D:早于时节上市的樱桃,由于供不应求会获得更多的经济利益

岳阳楼记(节选)

范仲淹

    若夫淫雨霏霏,连月不开,阴风怒号,浊浪排空;日星隐曜,山岳潜形;商旅不行,樯倾楫摧;薄暮冥冥,虎啸猿啼。登斯楼也,则有去国怀乡,忧谗畏讥,满目萧然,感极而悲者矣。

    若春和景明,波澜不惊,上下天光,一碧万顷;沙鸥翔集,锦鳞游泳;岸芷汀兰,郁郁青青。而或长烟一空,皓月千里,浮光跃金,静影沉璧,渔歌互答,此乐何极!登斯楼也,则有心旷神怡,宠辱偕忘,把酒临风,其喜洋洋者矣。

    嗟夫!予尝求古仁人之心,或异二者之为,何哉?不以物喜,不以己悲;居庙堂之高则忧其民;处江湖之远则忧其君。是进亦忧,退亦忧。然则何时而乐耶?其必曰“先天下之忧而忧,后天下之乐而乐”乎。噫!微斯人,吾谁与归?

泥古者愚(节选)

纪昀

    刘羽冲偶得古兵书,伏读经年,自谓可将十万。会有土寇,自练乡兵与之角,全队溃覆,几为所擒。又得古水利书,伏读经年,自谓可使千里成沃壤。绘图列说①干②州官。州官亦好事,使试于一村。沟洫③甫成,水大至,顺渠灌入,人几为鱼。由是抑郁不自得,恒独步庭阶,摇首自语曰:“古人岂欺我哉!”如是日千百遍,惟此六字。不久发病死。

    泥古者愚,何愚乃至是欤?何文勤公尝教昀曰:“满腹皆书能害事,腹中竟无一卷书亦能害事。国弈不费旧谱而不执旧谱国医不泥古方而不离古方。”

注释:①列说:游说。②干:求见。③洫(xù):田间水道。

    Chokwe Selassie, aged 13, is working hard to help drivers avoid potholes(坑洼). The eighth-grader was inspired to kick off his creation on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. He decided to do something about the pothole problem in his city. His solution: an app that warns drivers when there is a pothole ahead.

    Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. When the app detects a pothole, it is highlighted in red. And if you get close to the pothole, your phone will warn you. Drivers can also use the app to report any potholes they meet, and to look for other routes they can take to avoid roads that have them.

    The app relies on current available information about the streets of Jackson. It works by using the city's 311 call system, and uses information already stored in a database. Through the call system, citizens dial 311 to report non-emergency problems, which include potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test the prototype(原型).

    Although the app isn't yet available for sale,Chokwe is already looking for ways to improve it. The prototype remains limited to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther until it's nationwide.
