11.You can't always predict a heavy rain or remember your umbrella.But designer Mikhail Belvaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created Lampbrella,a lamp post with its own rain sensing umbrella.
The designer says he came up with the idea after watching people get wet on streets in Russia."Once,I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain.I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,"he said.
The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy.It has a built-in electric motor which can open or close the umbrella on demand.Sensors(传感器)then ensure that the umbrella offers pedestrians(行人) shelter whenever it starts raining.
In addition to the rain sensor,there's also a 360°motion sensor on the fiberglass street lamp which detects whether anyone's using the Lampbrella.After three minutes of not being used,the canopy is closed.
According to the designer,the Lampbrella would move at a relatively low speed,so as not to cause harm to the pedestrians.Besides,it would be grounded(埋地线) to protect from possible lightning strike.Each Lampbrella would offer enough shelter for several people.Being installed(安装) at 2meters off the ground,it would only be a danger for the tallest of pedestrians.
While there are no plans to take the Lampbrella into production,Belyaev says he recently introduced his creation to one Moscow Department,and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

分析 本文是一篇说明文,主要介绍了一款革新式的贴心路灯雨伞的发明.这款路灯既能照明,又能挡雨,让人们在下雨天没带雨衣或雨伞的时候也不必害怕被淋湿.它是一种安装在路边电线杆上类似雨伞的装置,当天开始下雨的时候,传感器向电驱动发送信号,从而能缓缓地展开雨伞,而当这个360度的全方位传感器发现伞下没有路人避雨时,便会在3分钟之后缓缓关闭.
解答 BCAD
32 B 猜测词义题. 根据文章第一 段You can't always predict a heavy rain or remember your umbrella 可知你不能总是预测到大雨的到来并且记得带伞,划线句子的意思是这个设计师不认为在外出前忘记带伞会让你淋湿,故选B.
33 C 细节归纳题.根据文章第三段中"It has a built-in electric motor which can open or close the umbrella on demand.Sensors(传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining."可知,先是发动机的运转,然后发动机打开伞,即"motor"控制"canopy",而"motor"的运动是受"sensors"的控制,三者的排列关系是sensors→motor→canopy.故选C.
34 A 主旨大意题.根据第五段中的关键信息"so as not to cause harm to the pedestrians…to protect from possible lightning strike和it would only be a danger for the tallest of pedestrians"可知,第五段主要描述了这种伞的安全性,故选A.
35 D 推理判断题.根据最后一段中的第一句"While there are no plans to take the Lampbrella into production…"可知,还没有计划要把雨水感应式路灯伞投入生产,故B项错误;文中未提及选项A"发明者将自己开办公司来推广他的产品"以及选项D"灯伞将在莫斯科举行展览".文中提到虽然没计划投入生产,但设计者把它介绍给了一个莫斯科的部门,而且他认为他的发明可以安装在行人多而无遮挡的灯柱上,可知,设计者对自己的发明充满信心,故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
