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(傘蓬)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(傳感器)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(埋地線) 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 本文是一篇說明文,主要介紹了一款革新式的貼心路燈雨傘的發(fā)明.這款路燈既能照明,又能擋雨,讓人們在下雨天沒帶雨衣或雨傘的時候也不必害怕被淋濕.它是一種安裝在路邊電線桿上類似雨傘的裝置,當天開始下雨的時候,傳感器向電驅(qū)動發(fā)送信號,從而能緩緩地展開雨傘,而當這個360度的全方位傳感器發(fā)現(xiàn)傘下沒有路人避雨時,便會在3分鐘之后緩緩關(guān)閉.
解答 BCAD
32 B 猜測詞義題. 根據(jù)文章第一 段You can't always predict a heavy rain or remember your umbrella 可知你不能總是預(yù)測到大雨的到來并且記得帶傘,劃線句子的意思是這個設(shè)計師不認為在外出前忘記帶傘會讓你淋濕,故選B.
33 C 細節(jié)歸納題.根據(jù)文章第三段中"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."可知,先是發(fā)動機的運轉(zhuǎn),然后發(fā)動機打開傘,即"motor"控制"canopy",而"motor"的運動是受"sensors"的控制,三者的排列關(guān)系是sensors→motor→canopy.故選C.
34 A 主旨大意題.根據(jù)第五段中的關(guān)鍵信息"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,第五段主要描述了這種傘的安全性,故選A.
35 D 推理判斷題.根據(jù)最后一段中的第一句"While there are no plans to take the Lampbrella into production…"可知,還沒有計劃要把雨水感應(yīng)式路燈傘投入生產(chǎn),故B項錯誤;文中未提及選項A"發(fā)明者將自己開辦公司來推廣他的產(chǎn)品"以及選項D"燈傘將在莫斯科舉行展覽".文中提到雖然沒計劃投入生產(chǎn),但設(shè)計者把它介紹給了一個莫斯科的部門,而且他認為他的發(fā)明可以安裝在行人多而無遮擋的燈柱上,可知,設(shè)計者對自己的發(fā)明充滿信心,故選C.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
