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 (伞篷) 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 (传感器) 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.
51.For what purpose did Belyaev create the LampbrellaA?
A.To protect people from the rain.
B.To check the weather forecast.
C.To predict a heavy rain.
D.To remind people to take an umbrella.
52.What do we know from Belyaev's words in Paragraph 2B?
A.It rains a lot in the city of Saint Petersburg.
B.His creation was inspired by an experience.
C.Street lamps are protected by canopies.
D.He enjoyed taking walks in the rain.
53.Which of the following shows how the Lampbrella worksC?
A.motor→canopy→sensors
B.motor→sensors→canopy
C.sensors→motor→canopy
D.canopy→motor→sensors
54.Paragraph 5mainly tells us aboutC of the Lampbrella.
A.its moving speed B.its appearance
C.its safety D.its installation
55.We can infer from the last paragraph thatB.
A.the designer will open a company to promote his product
B.the designer is confident that his creation is practical
C.the Lampbrella could be put into immediate production
D.the Lampbrella would be put on show in Moscow.
分析 本文是一片说明文,文章介绍了雨伞的设计师对雨伞设计的详细过程,详细介绍了设计的理念和雨伞的组成,如雨水传感器等部件.人们可以通过这篇文章了解到雨伞的基本情况.
解答 51.A细节理解题.题目问的是 Belyaev 创造 Lampbrella的目的是什么.根据文章中的"The designer says he came up with the idea after watching people get wet on streets in Russia"可以看出这个发明的目的是为了防止人们淋雨,故选A.
52.B 推理判断题.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 (伞篷) built into a street lamp,"是作者的亲身经历,由此产生了这个创意,故选B.
53.C 排序题,根据第三段的"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."伞棚的打开或关闭是先由传感器(Sensors )来接受然后motor来操控,故选C.
54.C 主旨大意题.根据第五段中的"so as not to cause harm to the pedestrians"和"protect from possible lightning strike"可知此发明体现了其安全性.故选C.
56.B 推理判断题.根据最后一段中的"and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter."可以推理设计者对它的创意很有信心.故选B.
