The city has five parts: Manhattan, Brooklyn, the Bronx, Queens, and Staten Island — each having its own lifestyle.     3     (move) from one city to the next may be like passing from one country to     4    .

For the past two     5     (century), New York City has been the largest and     6     (busy) American city. Over half the people and goods that ever entered the U.S. in the past came through its port (港口). New York City means     7     (possible) because it is always on its way to something better. However, it has also become a goal for international terrorism (恐怖主义).

5 . The Best Caves in The World

Natural caves don’t come much larger than Hang Son Doong, close to the border between Laos and Vietnam. This cave possesses the largest cross-section of any known cave on the planet, a vast area that is difficult to describe. Supposedly, a Boeing 747 could fly through without damaging its wings, but that doesn’t really do justice to the vastness of Hang Son Doong. The stalactites (钟乳石) here are pretty massive too, with some reaching up to 80 metres.

Glowworms (萤火虫) are there, as far as the eye can see. Okay, not literally, but the Waitomo Cave system on New Zealand’s North Island is best-known for the fluorescent fauna that light up the walls, giving it the not-particularly-creative but completely acceptable “Glowworm Caves” nickname. They are more accessible than other caves on this list, with rafting and adventure tours available to those looking for something a little more thrilling.

If you have certain expectations from somewhere called “Mammoth Cave”, that is entirely understandable. Mammoth Cave in Kentucky is the world’s longest known cave system, an incredible 420 miles of underground wonder. That’s twice as long as the next longest, by the way, although it isn’t unusual for the USA to go all out on such things.

Named after the reeds that grow outside, which are used to make flutes, obviously, the Reed Flute Cave’s walls are covered with inscriptions from centuries gone by—if evidence was needed that people have been paying attention to this place for a long old time. The inside part of the cave is also lit up by multicoloured lights, giving it a real otherworldly theme that adds weight to the nickname.

7 . National parks are an excellent way to explore all the beauty that the world has to offer: whether it’s endangered species, erupting volcanoes and snowy mountains, or rainforests and lakes. Of the thousands of national parks that exist in the world, these are the ones that should be on everyone’s bucket list.

Contrary (相反) to the popular link of national parks with the wilderness, it is filled with winding valleys, hills and villages where over 24,000 people live and work. Visitors can walk through grassland, visit waterfalls or explore underground caves, but Yorkshire Dales is also home to several food shops, and the park hosts cheese festivals and farmers markets regularly, so it’s best to go hungry.

It is a delight for those who like a bit of history mixed with the biodiversity of national parks. While it houses thousands of species of wildlife, there’s more to the national park than that.

It is surrounded by striking natural beauty and can be explored by land. But the river national park, as the name suggests, is best explored through leisurely boat rides that take visitors through many ancient towns that come along the way of the river.

Here’s a surprising fact: The whole of Vatnajökull National Park makes up 14% of Iceland’s territory! The park is usually open for hikes around the glaciers; boat rides through glacier lakes, and tours that take visitors through the park’s many ice caves, waterfalls, and icebergs. Vatnajökull is also where two of Iceland’s most active volcanoes are located.

The Baihetan hydropower plant, China's second largest hydropower facility on the upstream branch of the Yangtze river, was     1     (formal) completed on Tuesday after the last generating unit was connected.

The plant is estimated to generate 62.44 billion kilowatt-hours annually,     2     could save about 90 million tons of coal a year and cut annual carbon dioxide emissions (排放) by about 248 million tons.

Baihetan is one of six huge hydropower     3     (station) along the Yangtze river, China's longest. The Three Gorges Corporation, the project's developer, has described the 289-meter dam (大坝) and     4     (it) associated facilities as one of the country's biggest and     5     (challenging) engineering projects.

Construction began in 2017, with a total investment     6     (estimate) at 170 billion yuan. As     7     major project in China's west-east power transmission (输送) program, it will deliver electricity across the country     8     cities in the east.

China goes on     9     (construct) hydropower plants in the southwest, despite a long and severe drought in the summer of 2022 that saw generation volumes drop, forcing regions     10     (limit) power consumption.

Auckland is the largest city in New Zealand. It has a population of just under a million people and is located     1     North Island. The seaside city is an important center for business and industry. It is also the most     2     (excite) city in New Zealand. Auckland was the capital of New Zealand for some time. Later, the capital moved to Wellington,     3     it was more central. In 1985, the New Zealand government     4     (make) the whole country a nuclear-free zone and since then Auckland has been a center for protest against nuclear testing in Asia pacific.
