The wilderness(荒野) is one of Canada’s treasures and the Canadian national parks are the system through     1     the Canadian government protects, preserves and displays some of the country’s most     2     (impress) territory for the benefit of residents, visitors and the environment.

Every national park in Canada is a little bit different, but the majority are     3     (heavy) forested areas with mountainous landscapes that get snowy in the winter. Most national parks can be used     4     hiking, cycling and camping, as well as skiing during snowy months.

All of Canada’s national parks     5    (run) by the Canadian federal government and many have unique rules that must be obeyed. In theory, any park can be visited,     6     many national parks do not permit camping outside of campsite areas, or require campers     7    (get) permission to camp in advance. While the majority of national parks have government facilities within them, such as visitor centers or ranger stations(护林站) to provide emergency     8    (assist) for visitors, many do not,     9    (mean) visitors may be taking     10     serious personal risk when exploring. Canada is famous for its wild animals, which tend to be numerous in national parks.

3 . Banff National Park is Canada’s firstborn national park and was recognized in 1885. Located in the Rocky Mountains of Alberta, Banff includes 6,641 square kilometers of glaciers and ice fields, thick coniferous forest, and alpine(高山的) scenery. The Icefields Park-way spreads from Lake Louise, connecting to Jasper National Park in the north. Provincial forests and Yoho National Park are neighbors to the west while Kootenay National Park is situated to the south. The main commercial center of the park is the town of Banff, in the Bow River valley.

The Canadian Pacific Railway was contributory in Banff’s early years, building the Banff Springs Hotel and Chateau Lake Louise hotel in the park and attracting tourists through widespread advertising. In the early 20th century, roads were built in Banff, at times by prisoners of World War I, and through Great Depression-era public works projects, As Banff has over three million visitors annually, the health of its ecology has been endangered. In the mid-1990s, Parks Canada launched a two-year study to preserve ecological integrity.

Banff National Park has a subarctic climate(副极地气候) with three ecoregions. The forests feature lodgepole pine at lower heights and Engelmann spruce at higher ones below the tree line, above which are chiefly rocks and ice. Mammal(哺乳动物) species such as the grizzly bear, cougar, wolverine, moose and bighorn sheep are found along with hundreds of bird species. Reptiles(爬行动物) are also found but only a restricted number of species have been recorded.

The mountains were formed from sedimentary rocks(沉积岩) which were pushed east over newer rock formations, between 80 and 55 million years ago. Over the previous few million years, glaciers have at times covered most of the park, but today are found only on the mountainsides though they include the Columbia Icefield, the largest continuous glacial mass in the Rockies. Erosion(侵蚀) from water and ice has molded the mountains into their existing shapes.

I was born in St Ives but I moved away from home at a time when I thought the grass was greener. I soon learned that I already had     1     I had been looking for all along and fell in love with my hometown when I moved back from London.

I love the character of the people and     2     the streets in St Ives. I love that I can access the wild outdoors just beyond my doorstep. For me, being a St Ives resident means the opportunity to be     3     (create) and celebrate the diverse art scene we have here. There is an interesting duality (双重性) in St Ives - conservative and liberal people     4     (rub) shoulders in almost equal numbers, which pretty much sums up the spirit of St Ives.

Sadly I do believe St Ives     5     (become) a victim of its own success, much to the detriment of those (especially younger people) wanting to settle here. House prices are at an all time high and the vast     6     (major) of jobs are minimum wage. Many     7     (depend) shops are priced out of leases (因租金过高而被挤走) only to be swiftly replaced by bigger brands.

Nature lovers     8     (draw) to St Ives thanks to the beautiful sea, the wild coast and the wildlife. It     9     (true) is the most incredible playground for those who find their joy in getting outdoors. Walking, hiking, cycling, coasteering, sailing, swimming-we have it all. I created the St Ives Mermaid idea    10     a way of giving back to my hometown. It gives me the opportunity to entertain locals and visitors while also raising money for charity.

7 . Depths of our Earth hold great wonders. Below we explore four deepest places on Earth.

Its entrance is located 2,285 meters above sea level. In 2018, scientists reached its bottom at 2,212 meters down. They squeezed through tiny openings to get from one cave to another. Rockfalls and floods waited secretly at every turn. Scientists could develop new medicines from microorganisms found in cave samples. Caves also record ancient life and past climates.

The Mariana Trench, with the maximum depth of 11,034 meters, is the deepest part of Earth’s surface. Pressure there is intolerable, but creatures like sea cucumbers (海参) still exist. Scientists exploring it can gain deeper insights into how plates move and why earthquakes and volcanoes occur.

The Dead Sea is the lowest point on land at about 1,400 feet (about 400 meters) below sea level. It’s nearly ten times saltier than ocean water, so you literally can’t sink in the Dead Sea! Scientists think it could go dry in a few decades. Despite its name, the Dead Sea holds life. A few kinds of algae (藻类) and bacteria love its salty water.

At the depth of 1,642 meters, Lake Baikal is the deepest inland body of water. The Baikal seal is the only known seal that lives in this world’s deepest freshwater lake. Scientists study the lake not only for the solid stuff beneath it that records climate history but because it’s in a zone where a plate is splitting apart, causing earthquakes.

As the longest man-made river in the world, the Grand canal claims an     1    (influence)place in China.

The original canal system began around AD 605,     2     completion was owed to the Emperor Yang of Sui Dynasty. He found it necessary to possess a better way to feed his army,     3    (specific), a way to move food quickly from China’s southern rice-growing region to the north. So, the emperor ordered the construction of the first section of the Grand Canal,     4    (connect)existing canals, lakes, and rivers. An     5    (estimate)one million people worked on the construction, which took six years. But there is no doubt that the canal actually promoted China’s economic development, even today.

And     6     it comes to the canal, its cultural function can’t be ignored. Some critics even think that     7     the Grand canal, the advanced ideas, regional foods and cultural practices couldn’t have been transported from one part of China to another smoothly and quickly. According to legend, this is how Beijing acquired two of its best-known trademarks. Peking duck, a dish from Shandong Province, and the Peking opera, from Anhui and Hubei regions,     8    (bring)north via the canal.

In 2005, a group of citizens proposed that the Grand Canal be made a UNESCO World Heritage Site, which would protect both the waterway and the architecture around it. With great efforts, the day people had been looking forward to     9    (come)in 2014, when UNESCO status was officially granted. The hope now is that the Grand Canal—one of the world’s great engineering     10    (accomplish)—will continue to link north and south China for centuries to come.

10 . On September 15, El Salvador, Guatemala, and Honduras celebrate their own independence days. On October 16, Mexico follows suit. Each country above has its own nature, but what combines them is local traditions and Spanish culture. Here are four destinations worthy of planning a trip.

Tazumal, El Salvador

El Salvador is home to some rather impressive Mayan ruins that show off this once great civilization. Tazumal is one such place, which is believed to be more than 7,000 years old and was left abandoned sometime around the 13th century. However, large areas were extensively restored in the 40s’ and 50s’, giving visitors a taste of the past.

Antigua, Guatemala

The 16th-century city of Antigua is surrounded by volcanoes, churches, and Baroque buildings, combining European style with pre-Hispanic traditions, making its way to the list of UNESCO World Heritage Sites. It’s possible to visit most of its attractions on foot, including the Arco de Santa Catalina, the Central Park, and the Palacio del Ayuntamiento.

Comayagua, Honduras

Honduras may be well-known for its beaches, and one worthy of your travels is the city that was once the capital: Comayagua. Founded in the early 1500s, a visit here is like traveling back in time. Several museums showcase the cultural richness and the must-see clock in the central square, which is the oldest clock in the continent, dating back to the 12th century.

Veracruz, Mexico

Veracruz is a natural beauty with beaches that stretch for as far as the eye can see, deep blue waves and powerful waterfalls. When visiting Veracruz, stop by the Zocalo in Downtown Veracruz, where locals gather to listen to “son jarocho”, a regional folk music style that started right here. Couples also gather to dance in the square. But not just any dance, rather they take part in Danzόn, a traditional couples dance iconic (标志性的) to this particular state.
