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 Cryo­2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason­1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar 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 smaller­scale 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.

12.The passage is likely to         .

A.be an advertisement                   B.appear on VOA

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

13.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.

14.Scientists collected and studied information by       .

A.the European Space Agency's Cryo­2 satellite

B.the American space agency's Jason­1

C.sonar equipment on ships

D.the Cryo­2 and the Jason­1

15.What's the best title of the passage?

A.Scientists Create New Maps of Ocean Floor

B.Scientists Know More Oceans Than Mars

C.Oceans Will Provide Us With Maps

D.People Know Easily About Mars

As a father who works outside the home, I recognize that it is easy for me to get caught up in stress at work. Indeed, sometimes it is difficult to turn off my work focus and turn on my family focus so that I can come home and be the loving husband my wife needs and the playful father my kids want.   16  Good fathers provide stability and strength to the family. As fathers, we do not let the pressures and worries of work get in the way of being there for our kids.

17

1.  18   It doesn't need to be a lot of time, but if you are able, have one­on­one time with each of your kids.

2.Be goofy (滑稽的) with your kids. The more voices you do, the more expressive you are when you play with them, the more they will feel your love and your acceptance of them.

3.Spend time reading to them. Allow your kids to choose a book and spend time reading some of it to them before bed. The more effort you put into it the more they will feel your love.  19

As a therapist (临床医学家)  who works with children and their families, I have noticed that the better the relationship that a father has with his child, the more influence that father will have on his child. As fathers work on developing a strong link with their kids through positive interactions, they can have a positive effect on  the lives of their children.   20

A.Fathers have such an important and irreplaceable role in the family.

B.Sometimes books can help you deal with children.

C.Reading stories is an excellent time for dads to practice voice imitations.

D.Here are some thoughts to help fathers keep their little ones in mind.

E.As a father he must involve hardships in all his life.

Dear editor，

I'm sorry to occupy your precious time, and I really want to tell you anything about the problem of some people keeping too many pets nowdays. I take the problem more and more seriously for the following reason.

First of all, as it is known to people, pets make so much noise that trouble residents a lot. What's more, it is widely accepted that animal waste pollutes the environment, where makes people quite uncomfortable. Many owners like taking their pets to public place where they may frighten children or even bite people. The mostly important is that pets can spread some diseases and this has attracted much attention.

Take all these factors into consideration, I sincerely hope that I can get help from you and expect the media do something for this.

Yours truly，

Wang Lin
