Washington D. C. is the capital of the United States. It's the center of the national government. It's a busy, working city with a large population. But what is more, Washington is also a city of history and culture.

Washington was created in 1790, when Congress (国会)decided to place the nation's new capital in the east of the country. It was built halfway between the northern and the southern states of the America. And of course it was named after George Washington, the first President of the United States.

There are many tourist sights in Washington. One of them is the White House. This is the home and office of the President of the United States. Most visitors are, however, surprised by how small the White House actually is.

Washington is also a great culture city. The Library of Congress contains one of the largest library collections in the world. The Smithsonian Museum holds the nation's largest collection of cultural materials. And John F. Kennedy Center is a famous center of art and culture. It has many great musical and theatre performances throughout the year.

I did not go on my first hike until my mid-30s. I could blame it on the fact that I grew up on the Great Plains of South Dakota and North Dakota. Having never gone, I didn't see the value and always shook my head when asked.

At the urging of my wife, and with my two young kids, we walked a beautiful forest path on a cool August morning. I carried a small backpack with water and snacks (小吃). When we reached the top, we ate lunch together overlooking a perfectly still pond and scenic Vermont.

A few weeks ago, my 11-year-old son, my 61-year-old dad, and I hiked Camelback Mountain in Phoenix. Last weekend, I hiked down the Grand Canyon with my son along the South Kaibab Trail. And later this week, my wife and daughter will join us to walk the Waterfall Trail in the White Tank Mountains.

Now, just to be clear, by no means would I classify myself as an expert hiker. And I have no plans to climb Mount Kilimanjaro or walk the Appalachian Trail. But waking early on a Saturday morning to walk 3-5 miles along a forest path with lunch in the backpack is a journey I'd recommend to anyone.

It is healthy physical exercise that creates wonderful memories. And given the chance, hiking teaches us important truths about life.

A. Most of our hikes only last 2 hours.

B. I've fallen in love with climbing mountains.

F. It provides an opportunity to slow down and disconnect.

G. I went on my first hike a few years back while living in Vermont.

In my 40s, as a new solo (独自的) traveller, I spent endless time looking around souvenir shops in tourist areas. It never1me that in shops where merchants weren't 2big rents, I could save more money. Besides, I didn't give much 3for the size of what I was buying.

I learned and 4. But I also found that over time, the objects that were 5 to me changed too. As my tastes matured, my bags got smaller.

In my 50s I 6 boxes from around the world. These were small so they 7 easily into every place of my backpack.

Then a 8 thing happened. My interest in the collection 9 while my grandchildren's interest in it grew, so a wonderful and new 10 began. Each time a child came to visit, he or she was 11 to pick a box. My popularity 12 increased among the children, and pretty soon my collection had been 13 among the little people in our family. Each gift was 14 by a mini travel story explaining where the 15 was found, who had made it and what that country was like.

Most of us are familiar with the "Silk Road", a network of land trading routes which connected northwestern China to Europe since the Han Dynasty. With its recent (popular), you may have heard of the "Ancient Tea Horse Road" as well, another network of land trading routes that connected China to various (part) of Asia and Europe before sailing became common. Historically, the "Ancient Tea Horse Road" is no less (value) than the "Silk Road". And because of their respective locations (位置), sometimes the "Ancient Tea Horse Road" (refer) to as the "Southern Silk Road".

The "Ancient Tea Horse Road" got its name as Chinese tea and horses were the main products (buy) and sold along the route.

The "Ancient Tea Horse Road" was (far) developed during the Song and Ming Dynasties, and remained busy trading route all year round until the Qing Dynasty.

The "Ancient Tea Horse Road" served not only a trading route, but also a bridge connecting different races—such as Han and the Tibetan people. It is located near the "Roof of the World", and is where many ethnic groups are located, (make) it a spot of many attractions.
