From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its original push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle (角度).

You’re having a blast at your friend’s birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.

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 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 2 meters 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.

1.For what purpose did Belyaev create the Lampbrella?

A．To predict a heavy rain.

B．To check the weather forecast.

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.

3.Which of the following shows how the Lampbrella works?

A．motor→canopy→sensors

B．sensors→motor→canopy

C．motor→sensors→canopy

D．canopy→motor→sensors

4.What does Paragraph 5 mainly tell us about the Lampbrella?

A．Its moving speed.

B．Its appearance.

C．Its installation.

D．Its safety.

5.What can be inferred from the last paragraph?

A．The designer will open a company to promote his product.
