【简答题】
You can’t always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv 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 come 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 shelter whenever it starts raining. In addition to the rain sensor, there’s also a 360°motion sensor on the biberglass 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 to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians. While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter. 小题1:For what purpose did Belyacv create the lampbrella? A.To predict a heavy rain B.To check the weather forecast C.To protect people from the rain D.To remind people to take an umbrella 小题2:What do we know from Belyacv’s words in Paragraph2? A.His creation was inspired by an experience B.it rains a lot in the city of Saint Petersburg C.Street lamps are protected by canopies D.He enjoyed taking walks in the rain 小题3:Which of the following show how the lampbrella works? A.motor→canopy→sensors B.Sensors→motor→canopy C.motor→sensors→canopy D.canopy→motor→sensors 小题4:What does paragraph 5 mainly tell us about the lampbrella? A.Its moving speed B.Its appearance C.Its installation D.Its safety 小题5:What can be inferred from the last paragraph? A.The designer will open a company to promote his product B.The lampbrella could be put into immediate production C.The designer is confident that his creation is practical D.The lampbrella would be put on show in Moscow
