1 . Named “America’s Finest City” due to its hospitality, beauty and ideal climate, San Diego is located on the border with Mexico. The residents are so active outdoors that it is called “Sportstown, the U.S.A.”. San Diego’s 70 miles of beaches are a heaven for swimmers, surfers, divers, boaters and sunbathers. Another favourite outside activity is golf. With 100 courses (about 50 of them public), San Diego is a golfers’ paradise. Many San Diego residents came here first as tourists, who were attracted by San Diego’s sunny beaches, nearby mountains and deserts, plus the cultural delights of any big city. The world-famous San Diego Zoo, SeaWorld Adventure Park, Wild Animal Park, museums and other attractions attract visitors from around the world.

The zoo is home to some 4,000 animals, including the world’s largest group of parrots. Animals are displayed in natural settings, and there is a petting zoo for children. By contrast, the Wild Animal Park is a wildlife preserve with an area of over 2,000 acres and more than 3,000 free-roaming (自由漫步的) animals in natural habitats.

In addition to housing the zoo, Balboa Park is home to several museums and attractions, including an aerospace museum, an art and history museum, the Old Globe Theatre, science museums and even a railroad museum. Free concerts are offered frequently. Another popular attraction is the SeaWorld, a 190-acre marine park.

San Diego’s varied attractions, as well as its business climate, offer many opportunities for students to explore the local culture, meet people from around the world, and gain business experience. At San Diego State University, for example, students in the American Language Institute’s study tour program learn English both in the classroom and while sightseeing.

4 . The Silk Road is arguably the most famous lung-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profit travelling the road, it was not without risk.

The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.

The Gobi Desert, the largest desert in Asia, consists-mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.

So, rest stops were created along the route, allowing travelers to rest, cat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.

Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. Whilst this part of the journey may have been less dangerous, it is not entirely without its perils.
