Lǎozìhào refers to the old and famous shops, which have always been reliable and trustworthy and still enjoy     1     irreplaceable position in people’s minds since long time. Not only do they represent high quality and good reputation, they have also become an indispensable part in     2     (people) daily life.

These famous and time-honored shops, eg, Quanjude and Tongrentang,     3     (locate) in Qianmen, the center of Beijing, all have represented the highly developed     4     (commerce) culture of old Beijing.

But these shops are more about businesses; they are also a historical and cultural phenomenon. He     5     has never tasted a roast duck will regret his whole life--such common sayings have made Quanjude a     6     (represent) of Beijing. Many other similar two-part allegorical sayings among the folks have also     7     (vivid) revealed the very characteristics of these old shops.

Nowadays, with the rapid development of economy and fierce competition in modern society, some Lǎozìhào shops have been keeping pace     8     the times and carrying forward their brands through continuous reforms and innovations. That’s why they    9     (stand) the test of time and survived in competition, while some others have faded into the history due to their inability     10     (adapt) to the rapid changes in modern social life.

The Amazon River surprisingly has no bridges when     1     (compare) with some of the world’s other most recognizable rivers. There are about nine bridges over the River Nile in Cairo alone. More than 100 bridges     2     (complete) in the last 30 years across the Yangtze. While Europe’s Danube is only one-third as long as the Amazon,     3     has 133 bridge crossings. So what’s the deal with the Amazon?

The Amazon     4     (flow) through areas that are barely populated, meaning there are very few major roads for any bridge to connect to. And in the cities and towns     5     border the river, ferries are     6     established means of moving goods and people from bank to bank, meaning there is no real need for bridges     7     (build), other than to make trips a bit quicker.

Besides, the Amazon is far     8     an ideal location for bridge builders, as it has a large number of natural blocks that would need to be conquered by engineers and construction workers. Additionally, the changing positions of the river’s course across the seasons, with great differences in water     9     (deep), would make the construction extremely     10     (demand).

4 . Four Peak District waterfall walks

The Peak District National Park offers beautiful scenery for hiking. One exciting attraction is the region’s waterfalls. We’ve picked out four of the most breathtaking waterfall walks; visit just one or tick off all of them as you discover the Peak District.

Kinder Downfall

If there’s one Peak District waterfall that you must visit, it’s this one. Kinder Downfall is one of the best Great British waterfalls, where you can watch a 30-metrestream of water flowing from an open plateau at Kinder Scout. It’s best to schedule your visit after heavy rain when the waterfall is really in full force.

Lumsdale Falls

If you feel like stepping back in time, take a trip to Lumsdale Falls. The area includes many 17th-century mill (磨坊) buildings which used to be powered by the nearby rivers, and the ancient ruins create a timeless atmosphere in the beautiful Lumsdale Valley.

Padley Gorge

The journey to this waterfall has a charming, fairy-tale feel, making it perfect for a fun day out as a family. The walk is around an hour each way, but there are plenty of picnic spots where you can all refuel, as well as areas for little feet to safely paddle in the chilly water.

Rivelin Valley

Make sure you pack your camera when you visit this waterfall in the Rivel in Valley, as it’s one of the most picturesque spots in the Peak District. Follow the nature trail through the woodland where you’ll find dams, reservoirs, streams and a series of very pretty waterfalls.

6 . A 2020 study in the journal Science concluded that marine heat waves have increased more than 20-fold as a result of climate warming. The authors found that in the first decade after satellites began recording ocean temperatures (i.e., after 1981), there were 27 large marine heat waves, with an average duration of 32 days and an average peak temperature anomaly of 8.5°F; in the 2010s, there were 172, which lasted 48 days on average with an average peak temperature almost 10°F above normal.

Much remains unclear about marine heat waves. For example, explains Nicholas Bond, research scientist at the University of Washington and Washington’s state climatologist, there is the question of why so many persist for weeks or months. “There must be something else going on that helps maintain them,” he says. He notes that one explanation is that as the ocean surface warms, it radiates heat into the atmosphere that prevents cloud cover from forming, exposing the seawater to increased sunlight and further warming.

However, enough is known about marine heat waves for scientists to be gravely concerned about their potential impacts. Of special note is the fact that those impacts can last long after the heat waves have disappeared. After three years of the Blob, the waters of the northeastern Pacific began to cool in 2016; but years later, scientists are still determining the extent to which the region’s ecosystem is likely to return fully to its pre-Blob status. Similarly, notes Scannell, who is a data scientist with Jupiter Intelligence, Inc., following the 2010-11 Western Australia event, “lots of kelp(巨藻) forests died, and it takes literally decades for those ecosystems to bounce back”.

Eric Oliver, a scientist from Dalhousie University in Nova Scotia, Canada, expressed his own opinion about the potential impact of the heat waves in tropical waters. “I think that’s really a tough issue,” he says. Life in the tropics, he notes, is adapted to “quite a narrow range of temperatures. So that’s where things can get really messy. We can have complete shifts in tropical systems.”

Beijing is a city that straddles(跨越)the divide between the ancient and the modern. It is home     1     more than 3,000 years of fascinating history, and a place     2     fully embraces the fast-paced development of modern life, with high-rise 21st-century architectural wonders standing side by side with cultural relics of the past.

This integration of styles     3     (be) strikingly typical at Zhihua Temple, built in 1444 during the rule of emperor Zhengtong. Though much smaller now than at its peak of 20,000 square meters, the temple is a somewhat     4     (hide) treasure.

    5     (remarkable), the temple museum offers a collection of remains and statues. You might even forget you’re in the 2lst century, if not for the smooth curve of the modern Galaxy Soho building looming over the mythical beasts(神兽)seated on the ridges(屋脊)of the temple roofs.

Yet     6     they belong to completely different     7     (era),   appearances and purposes, they are both equally representative of this city. Seeing the two together is a perfect example of the idea of how respecting our history, while still     8     (look)to the future, can create a truly unique cityscape.

The development of this city, which is carefully designed     9     (protect)the past while embracing the modern world,    10     (mean)there is always something new to discover here, and I could be photographing Beijing for the next 50 years and still not have scratched the surface, which is part of its beauty.

There are certain things on the Earth that we must not lose. The great animal migration across the Serengeti Plains or the towering pyramids of Egypt are such examples. Every country is proud of     1     (it) cultural or natural heritage sites,     2     must be protected. We are lucky to have UNESCO to oversee such an important task. It sees heritage as our legacy from     3    past, what we live with today, and what we pass on to future generations as well as sources    4    irreplaceable inspiration.

The incredible splendour of heritage sites is a     5     (remind) of the power of nature and the genius of man. As a nature reserve, Jiuzhaigou Valley is home to snow-capped mountains, thick forests, impressive waterfalls and lakes. This dream-like scenery makes us realize that nature has    6     (true) created a masterpiece. Similarly, standing in the shadow of the Borobudur Temple, as the sun rises over this grand historic building, we    7     (impress) with the effort and determination of the people who     8    (build) it with only primitive tools.

It is in heritage sites like this     9     we cannot help but be humbled, come to understand our limitations as human beings, and know that our duty is to protect them for generations     10     (come).
