We know more about the surface of the planet Mars than we know about what is at the bottom of Earth’s oceans.

Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers, industry and governments.

The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the Scripps Institution of Oceanography at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean. He spoke to VOA on SKYPE.

“The way we’re doing that is to use a satellite altimeter (高度计), a radar to map the topography (地貌) of the ocean surface. Now that seems sort of strange that you’d map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surface topography has these bumps and dips due to gravitational effects that mimic what’s on the sea floor.”

The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth’s orbit to watch sea ice. The other satellite is the American space agency’s Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar ( 声呐：利用声波探测水下物体的装置或系统) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.

“That enables us to look at smaller-scale features and also features that are buried by sediments in the ocean basins.”

The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.

In one place, three mountain ridges join at the same area. Huge tectonic (构造的) plates can be seen clearly there.

1.The passage is likely to _____.

A. be an advertisement　　　　　　　　　　　　 B. appear on VOA

C. make a comment on radar　　　　　　　　　　 D. appear on SKYPE

2.What will be mentioned in the following paragraph, according to the last paragraph? _____.

A. The detailed information about the place.

B. The more important thing in the ocean.

C. The things buried in the ocean.

D. Scientists told SKYPE they will explore at the same area.

3.Scientists collected and studied information by _____.

A. the European Space Agency’s Cryo-2 satellite

B. the American space agency’s Jason-1

C. sonar equipment on ships

D. the Cryo-2 and the Jason-1

4. What’s the best title of the passage? _____.

A. Scientists Create New Maps of Ocean Floor

B. Scientists Knows More Oceans Than Mars

C. Oceans Will Provide Us With Maps

D. People Knows Easily About Mars

COOL INVENTIONS

CHARGE ON THE GO

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 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）round the neighborhood has never been better.

WATER CLOCK

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.

LAND ROCKET

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the 1,000-mile-an-hour barrier. (The current record is 763 miles an hour.) a concept for now, the rocket-shaped car gets its initial 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.

COOL CAMERA

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.

1．According to the passage, the Venturi Eclectic______.

B．They are difficult to operate

C．They can be powered by water

D．They are environmentally friendly

3．The underlined phrase “having a blast” in the last paragraph means______.

A．looking at a picture     B．enjoying yourself
