【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 report before heading out should result in you getting wet. To protect people from the rain, he created lampbrella, a lamp post with its own rain sensing umbrella. The designer says he comes 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 all right to have a canopy(伞蓬)built into a street lamp.” he said. The lampbrella is a street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella in need. Sensors(传感器)then make sure that the umbrella offers the walkers whenever it starts raining. In addition to the rain sensor, there’s also a 360° motion sensor on the street lamp which finds out 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 low speed, so as not to cause harm to the walkers. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough protection for several people. Being fixed at 2 meters off the ground, it would only be a danger for the tallest of walkers. While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation to one Moscow Department, and insists this creation could be fixed on my street where a lot of people walk. 小题1:Who designed lampbrella? 小题2:Why did Belyacv create lampbrella? 小题3:How soon is the the canopy closed if it’s not being used? 小题4:Would each lampbrella offer enough protection for only one person or several people? 小题5:What is the main idea of the passage?
