】閱讀理解 閱讀下面的短文，然后根據(jù)短文內(nèi)容，在每小題所給的四個選項中選出最佳選項.

You can’t always know when there’ll be a heavy rain or when to take an umbrella with you. But designer Mikhail Belyaev doesn’t think that forgetting to check the weather report before going out should cause you to get wet in the rain. That’s why he created the Lampbrella—a lamp post (燈柱)with its own “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 Saint Petersburg street and saw people trying to hide from the rain under the street lamps. I thought it would be a good idea to have a Lampbrella built into a street lamp.” he said.

The Lampbrella is a street lamp fitted with an umbrella canopy(遮蓬). It has an inside electric motor(電動馬達) which can open or close the umbrella freely. The Lampbrella will offer people cover whenever it starts raining. After three minutes of not being used the canopy is closed.

According to the designer， the Lampbrella would move at a very low speed in order not to cause harm to people. What’s more， it would be grounded to protect from a possible lightning hit. Each Lampbrella would offer enough cover for several people. Being 2 meters off the ground， it would only be a danger for the tallest man.

While there are no plans to take the Lampbrella into production(生產(chǎn))， Belyaev says he recently introduced his creation to one Moscow company， and insists his creation could be on any street where a lot of people walk but there are no canopies to provide cover.

1.According to the passage， for what purpose did Belyaev create the Lampbrella?

A. To know when there’ll be a heavy rain.

B. To check the weather report.

C. To protect people from the rain.

D. To remind people to take an umbrella.

2.What can we learn from Belyaev’s words in Paragraph 2?

A. His creation was encouraged 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.

3.What can we infer from the last paragraph?

A. The designer will open a company to produce his creation.

B. The Lampbrella could be put into production at once.

C. The designer is confident that his creation is practical.

D. The Lampbrella would be put on show in Moscow.

4.The best title of this passage is .

A. A special umbrella - Lampbrella
