The Yellow River is the second longest river in China and the sixth longest in the world at the estimated     1     (long) of 5,464 kilometers. The distinctive yellow color is     2     the sand and mud it collects from the environment.

The Yellow River     3     (call) “the cradle (摇篮) of Chinese civilization”. The people living along the Yellow River as well as the river itself     4     (shape) a splendid civilization since ancient times.     5     you’re a history fan or not, the river is fascinating. Originating in the Bayan Har Mountains in Qinghai Province, it flows through nine provinces of China,     6     (run) into the Bohai Sea. The Yellow River basin has     7     area of 742,443 km². Two of the most popular spots to visit are the Hukou Falls and the Silk Road Crossing in Lanzhou. The Yellow River used to be called “China’s Sorrow” because of the     8     (frequency) floods hitting. In 1955, Chinese government developed a plan     9     (control) flooding and tens of thousands of trees have been planted along the     10     (bank) since then.

Li Daiyu and Liu Qin went on     1     unforgettable trip to Canada to visit their cousins on the Atlantic coast. Rather than take the airplane all the way, they     2     (take) the train west to east across Canada. The thought     3     they could cross the whole continent all the way was exciting.

They started their journey from Vancouver. People say it is Canada’s most beautiful city     4     (surround) by mountains and the Pacific Ocean. Its population is increasing     5     (rapid). On the northern coast of Vancouver,     6     is so wet that the trees are extremely tall.     7     are various interesting activities in the popular city, including skiing in the Rocky Mountains and sailing in the harbour.

That afternoon aboard the train to Calgary, the cousins settled down in their seats. They knew cowboys from all over the world would come     8     (compete) in the Stampede there. Many cowboys have a gift for riding wild horses.

From the wonderful trip, they learned that Canada is the     9     (two) largest country in the world, with 5,500 kilometers from coast to coast. They also learned most Canadians live within 320 kilometers of the USA border,     10     makes the north of Canada very empty.

8 . Love sugar-white sand beaches? Whether you’re looking to ski down the side of a mountain or surf in the sunshine, you’ll find the following three places in the best winter travel destination list.

The newly-built Coral Towers at the Atlantis resort (旅游胜地) in Paradise Island, Bahamas, with new next-door neighbor Marina Village, an open-air shopping and dining marketplace, are just two of the newest reasons to visit this Caribbean popular travel destination. Don’t forget about Aquaventure, the world’s largest open-air water park. With the average winter temperatures between the mid 60°F and high 70°F, it’s a perfect place to escape the cold.

Iceland in the winter is simply dreamy and temperatures aren’t as cool as you might think. Plus, there’s no better time than winter to view the Northern Lights. Short winter days mean you’ll have an even greater chance to catch the magic. An increasing number of flights in and out of Reykjavik make it easier than ever to visit.

Whether you come for the Pro Bowl in January, the new Toy Story land at Disney’s Hollywood Studios, or Supercharged ride at Universal Studios Florida, Orlando is yet another warm-weather destination for winter travel. The weather is at its best and the crowds are at their thinnest.

9 . Travel with a Green Conscience(良知)

Travel is a form of consumption, from jet fuel to trash. It’s up to you to determine how much waste you will produce on your trip. For me, seeing the world has been an education on the environment and the challenges we face.    1     Ironically, travel has made me “greener”.

● Take public transport or carpool. Public buses or trains are an eco-friendly option for getting around your destination. Many youth hostels have carpool sign-ups for popular trips, which is an exciting way to meet fellow travelers. On my first day in a new city, I get a map and start walking!     2    

● Be aware of food packaging and waste. As for packaging, to-go containers are made of Styrofoam, paper or plastic bags, which almost always end up in the garbage. Be conscious of your purchases. Street vendors (小商贩) sometimes offer delicious finger food, such as kabobs, which have little to no food packaging. Pack your own silverware(镀银餐具).    3     Every little bit helps.

●    4     As I backpacked through Thailand recently, I noticed that most of the trash littered on the beaches and in the streets was from tourists. It disgusted me. Why would you come all this way to see a beautiful beach, only to destroy it? I began picking up litter when I saw it and disposing of it properly. When I go on a hike and see trash on the trail, I pick it up. You can help compensate (补偿) for others by going the extra mile!

●Consider the sustainability of the ecosystem. Before traveling to a new country, do your research. Are the waters overfished? Do they import their meat from another country? How much meat, fish, grain does the average local eat? How much water, gas, electricity does the average local use?    5     Being eco-friendly will enhance your adventure.
