1 . Have you ever wondered what wild animals do when no one is watching?

Low cost, dependable and small modern cameras offered a big help. Cameras placed in hard-to-reach places have shot everything from small desert cats to larger snow-lowing cats in the northern Rocky Mountains. Scientists have been able to document the “private” moments of wildlife with leading technology.

Grant Harris is a government biologist with the United States Fish and Wildlife Service in Albuquerque, New Mexico. In his words, “there’s no doubt that these wild cameras are important tools to learn new information on wildlife.” Harris said some images help scientists see the eflects of climate change.

Researchers with the Wyoming Migration Initiative, or WMI, are among those using wild cameras along with global positioning systems, or GPS. But WMI director Matthew Kauffman says as those devices are limited, so is the amount of information they can gather from GPS. However, cameras can be left in very wild areas for days, weeks or even months. They can provide information on how many animals are moving over a given period of time.

Putting those cameras in place requires careful planning. Wild video can show details about animal behavior. However, wild cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way.

Even with such problems, wild cameras are clearly an important scientific tool in researching wild animals.

3 . The Mayan Indians lived in Mexico for thousands of years. The Maya were so bright that they achieved a lot. They had farms, temples and cities with many buildings. They knew much about nature and the world around them. This knowledge helped them to live a better life than most people of that time.

In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields of crops around it. The Maya planted seeds after they cleared the land. A farmer was able to grow crops that produced for several people. But not every Maya had to be a farmer. Some were builders or priests (祭司)．

The Maya believed in many gods. They built large temples to honor them. Skillful workers built cities around these temples. It was difficult because they had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing.

Although the Maya worked hard to build the beautiful cities, very few of them lived in them. Usually, only the priests lived in the cities. The other people lived in small villages in the forests. Their houses were much simpler. Most Maya lived a simple life close to nature.

Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from a deadly disease. They may have left because the soil could no longer grow crops. The lost secrets of the Maya are still beyond the reach of modern people. They are still one of our greatest mysteries.

4 . China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I’ve found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it’s the easiest and cheapest way to travel today. Bicycles also come in different colors --- silver, green, red, blue, yellow, whatever you want.

It’s fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks. Bicycles allow people the freedom to move about that cars just can’t provide.

Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.

My first ride home was orderly (守秩序的). To be safe, I stayed with a “pack” of bikers while cars on the streets came running swiftly out of nowhere at times. I didn’t want to get hit. So I took the ride carefully.

Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.

I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.
