Today, I had the good fortune to join the students from East Silver Spring Elementary School in Maryland as they walked and biked to school in celebration of International Walk to School Day. I want to thank Principal Morrow and the entire ESS community for welcoming me so enthusiastically.

Walk to School Day is a great opportunity for me to spend time with parents, kids, and teachers and to present our Safe Routes to School program and the First Lady Michelle Obama ’s Let ’s Move initiative （倡议）.

As a father, grandfather and former schoolteacher, I know how important it is that we provide students with safe choice to get to school while promoting exercise and healthy lifestyles. That ’s why I’ve embraced the Safe Routes to School program so wholeheartedly since I became Secretary of Transportation.

You know, we ’re looking at an increasingly sedentary （久坐的）generation of children. One out of every three kids in America is now overweight. And I admire the First Lady ’s effort to end this within a generation. Safe Routes to School is a natural partner for Let’s Move. For more than 10 years, Safe Routes to School has been making it easier for students to walk and bike from home to school. And ESS, where I walked today, is one of the earliest schools to participate.

We know this program has been enormously effective because of the steady increase in the number of kids walking or biking to school. And as we made our way down the street this morning I was reminded yet again of this program’s extraordinary work.

Look, walking and biking to school is good for students’ health. It’s good for the environment. And

it’s good for the entire community’s quality of life.

Everybody wins when kids take Safe Routes to School.

In recent years, remote-sensing technologies have become ordinary in archaeological fieldwork （实地考察）. Such tools for excavation produce rapid results and cause no damage to archaeological sites. They are highly accurate and usually cost effective. Here are three of the modern archaeologist’s most trusted remote-sensing tools.

As the simplest of the remote-sensing techniques that archaeologists use, aerial （空中的）photography allows experts to see aspects of a site that may be invisible from the ground, such as the way in which something such as a town, garden, or building is arranged and traces of old walls and roads. The technique involves taking photographs with conventional cameras and filming from airplanes, helicopters, hot-air balloons, or other airborne vehicles.

Geographic Information System (GIS) contains a large amount of field data archaeologists typically collect in and around excavation sites. While in the field, archaeologists use GIS on their computers to make and manage detailed site maps, and they can combine the results of remote-sensing tests with maps of the region created with the aid of Global Positioning System. Resulting maps sort the most archeologically promising areas and display these sites three-dimensionally.

Ranging in size from small handled models that one places against the ground to larger ones that one across a site, Ground Penetrating Radar (GPR) devices use low-power radio waves to detect

changes underground. Unlike traditional radar, which broadcasts into the air and uses a dish to focus the returned waves, GPR uses a small but sensitive receiver placed directly against the ground. Depending on their needs, archaeologists can adjust radio frequencies upward for shallow sites or downward for deeper areas, though GPR devices produce the greatest definition（清晰度）when reading depths of three feet or less.

4．We can learn from the text that the remote-sensing tools ________.

A. have been widely and efficiently used in archeology

B. help archeologists discover more archaeological sites

C. will replace traditional archeological tools

D. are more difficult to use than traditional tools

5．Aerial photography is helpful ________.

A. in reflecting the changes of an archaeological site

B. in taking large-sized photos of an archeological site

C. in seeing what can’t be seen on the ground

D. in analyzing how old an archeological site is

6．Ground Penetrating Radar (GPR) devices as different from traditional radar in that ________.

A. GRP devices can detect changes underground
