4 . A skywell, or "tian jing", is a typical feature of a traditional home in China. ________ a northern Chinese courtyard, or “yuan zi”a skywell is smaller and less exposed to the outdoor environment. They are________ seen in homes dating to Ming and Qing dynasties, which were designed to________different generations of relatives.

Although a skywell's size and design vary from region to region, it is always rectangular and located in the Core of a house, either________by rooms on four sides or three sides plus a wall. Skywells were designed to cool buildings before air-conditioning existed. When wind blows above a skywell house, it can enter the indoor space through the opening. Because outdoor air is often cooler than indoor air, the ________breeze travels down the walls to the lower storeys and create air ________ by replacing warmer indoor air,   which rises and leaves through the opening.

The main purpose of a skywell is to allow in light, improve ventilation (通风) and ________ rainwater. In Huizhou, a skywell is small but tall, and the rooms around it can ________ sunlight on hot days, enabling the bottom of the skywell to stay cool. ________ hot air inside the house can rise and escape through the opening above the skywell, which“works just like a ________”

As a(n) ________ space between indoor life and the outdoor environment, a skywell acts as an effective heat buffer(缓冲)to shield residents from the hot air outside. But the largest part of skywell's cooling effect actually comes when there are bodies of water in the enclosure.

Evaporated water cools hot air, a process known as evaporative cooling which is ________ in Huizhou skywells. In the past, Huizhou families collected rainwater in their skywells because they believed this could safeguard and boost their wealth. Skywells therefore have channels around them to ________ rainwater coming from the roofs.

Though existing in China for hundreds of years, in recent times they have often been forgotten by people who prefer modern________. Over the past two decades, however, due to a ________ of traditional Chinese architecture, skywell buildings have been making a comeback.

Zion National Park in Utah has plenty of trails, but Angels Landing may be the most breathtaking. Picture this. You begin the hike on the wide and well-maintained West Rim Trail. It follows the river and then crosses the bottom of the canyon, surrounded by 270-million-year-old layers of rock. Relaxing, right? Just wait for it. The trail then starts to climb via a series of switchbacks (急转弯) leading up the side of the mountain. Then more switchbacks: 21 tighter turns, called “Walter’s Wiggles,” where elevation levels rapidly increase. Your heartbeat is probably rapidly increasing at this point, too.

On top of Walter’s Wiggles, you can stop for a stunning view (perhaps with a marriage proposal) and a restroom stop while you contemplate (仔细考虑) the final stretch of the hike. If you’re afraid of heights, it’s best to turn back now. The last stretch is the real test of bravery.

The last half mile of the hike is what really ranks it as one of the nation’s most dangerous. Angels Landing itself is a fin-like formation jutting (突出) 1,500 feet out of the canyon, and this is where you make the final 500-foot climb. Guardrails and chains bolted (拴住) into the cliff help you keep from tumbling over the extremely steep ledge. You’re literally living on the edge, and you don’t want to trust the “angels” down there to catch you. Once you reach the top, however, it’ll all be worth it: 360-degree views of the canyon make a great backdrop for kicking back and having a meal before you come back down the way you came.

Angels Landing might be dangerous, but thankfully, not too many people have had fatal falls. According to the park website, seven people have died in the 100 years the park has existed. Still, this is a very vigorous hike. If you’re out of shape, bringing young children along, feel ill or prone to fainting, or are just plain afraid of heights, opt for an easier trail.

Angel’s Landing is a great hike for most of the year, besides the cold winter months when the trails could become dangerously slippery. Summer is the most popular time of year — and therefore the most crowded — but it can also get extremely hot, so opt for an early morning hike while the temperatures are still mild.

Sure, it’s dangerous, but there’s a reason this is one of Zion ‘s most popular hikes. If you’re up for the challenge, Angels Landing will definitely deliver rewards.

10 . Every summer, as a child, I spent with my parents the annual family holiday, flying away from our home in the West Midlands to their birthplace in Ireland.

I enjoyed it, but once, I behaved differently and left home. Package tours and long-distance flights became my idea of a holiday. I then went and ran into an Englishman who also came of Irish stock, and we both felt the urge to renew our knowledge of Ireland.

It was important for us to discover something different from our childhood visits. So that’s how we came to drive along the winding St John’s Point Peninsula (半岛) in Donegal, part of Ireland’s Wild Atlantic Way, to visit a unique part of the 20th-century history — the Donegal Corridor.

When anyone drives to the point where the land runs out, he sees giant white stones fixed firmly in green grass spelling out “EIRE” and “70”, while the Atlantic wind fiercely blows across the headland and the ice-white waves smash into the rocks below. The meaning behind the stones? They date back to the Second World War when St John’s Point was number 70 in a total of 83 Look Out Points (LOPs), observation stations set up and maintained by Ireland all around its coast.

There lies a bit of curious UK-Ireland history. Although Ireland was officially neutral during the war, the Battle of the Atlantic was being fought close to Irish shores, and these LOPs, staffed by local volunteers known as Coast watchers, passed on information on activities connected with the sea and weather fronts to London.

At St John’s Point, we were standing right under the Donegal Corridor, a long narrow area of airspace in which Ireland ensured safe passage during World War II to planes in the RAF (Royal Air Force) from bases in the UK-governed North of Ireland. The stone markings acted as reference points to aircrews.

Standing on this rough area of land surrounded by the wild and windy ocean brought home to us the conditions in which the Coast watchers and aircrews in the RAF cooperated in a shared history.

I revolted against my family tradition that summer, and I fulfilled my aim of discovering something new and absorbed all Donegal has to offer: empty golden beaches, mysterious ancient stone circles, folk music and crafts, and tasty food. I had fallen in love with Ireland all over again.
