5 . Liam Gamer was just 17 years old when he started out on his big adventure — a 32,000-­kilometer bike trip from Alaska to Argentina. In early January, 2023, he finally finished his trip, 17 months after he started.

Liam, an experienced cyclist, had previously ridden from Los Angeles to San Francisco. He made short videos of that trip, and shared them on the social media app TikTok, some of which became quite popular. After reading a book by adventurer Jedidiah Jenkins, who biked from Oregon to Argentina, Liam decided to cycle from Prudhoe Bay, Alaska, the northernmost point in the United States accessible by road, to Ushuaia, Argentina, the southernmost point of South America.

Liam set out on August 1, 2021. At first Liam’s parents weren’t too happy about him taking such a long bike trip by himself though it wouldn’t take that much money. But as he carried on, his parents became his strongest supporters.

After about three months, Liam had crossed the US, going south along the West Coast. By early December, he had reached Mexico, from which his parents came to the US many years ago. “So crossing the entire country on a bike and reconnecting with my culture and learning the language in the place my family is from is so deeply important to me,” Liam explained emotionally. But Liam also faced challenges in Mexico.

He was robbed in Mexico, and at one point, he considered quitting because the incredible heat made biking extremely difficult. In all, he was robbed five times on the trip. He got very sick more than once. In Colombia, he had a bike accident that left him injured and required surgery. In spite of it all, he kept going through rain, sun, heat, cold, deserts and mountains.

Liam finally arrived in his destination on January 10, 2023 — 527 days after he started. He had travelled through 14 countries along the way.

6 . 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.
