13.You can't always predict a heavy rain or remember your umbrella.But designer Mikhail Belyaev 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 (傘篷) 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 (傳感器) then ensure that the umbrella offers pedestrians 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 is 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 to protect from possible lightning strike.Each Lampbrella would offer enough shelter for several people.Being installed (安裝) 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 本文是一片說明文,文章介紹了雨傘的設(shè)計師對雨傘設(shè)計的詳細過程,詳細介紹了設(shè)計的理念和雨傘的組成,如雨水傳感器等部件.人們可以通過這篇文章了解到雨傘的基本情況.
解答 51.A細節(jié)理解題.題目問的是 Belyaev 創(chuàng)造 Lampbrella的目的是什么.根據(jù)文章中的"The designer says he came up with the idea after watching people get wet on streets in Russia"可以看出這個發(fā)明的目的是為了防止人們淋雨,故選A.
52.B 推理判斷題.第二段中的"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 (傘篷) built into a street lamp,"是作者的親身經(jīng)歷,由此產(chǎn)生了這個創(chuàng)意,故選B.
53.C 排序題,根據(jù)第三段的"It has a built-in electric motor which can open or close the umbrella on demand.Sensors (傳感器) then ensure that the umbrella offers pedestrians shelter whenever it starts raining."傘棚的打開或關(guān)閉是先由傳感器(Sensors )來接受然后motor來操控,故選C.
54.C 主旨大意題.根據(jù)第五段中的"so as not to cause harm to the pedestrians"和"protect from possible lightning strike"可知此發(fā)明體現(xiàn)了其安全性.故選C.
56.B 推理判斷題.根據(jù)最后一段中的"and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter."可以推理設(shè)計者對它的創(chuàng)意很有信心.故選B.
