A park in Arouca, Portugal opened a new bridge. Though it's quite high，it's the     1     (long ) of the bridge that has set a record. It's the world's longest hanging bridge for walkers-over five football fields long.

It's a suspension (悬索桥) bridge,     2     means it hangs between two mountains without any supports underneath. The builders say the bridge was inspired by suspension bridges     3     (build) by the ancient Inca people in South America. It was started in May, 2018 and it took the builders over two years     4     (complete) the project.

But even though the bridge is     5     ( solid) made, it's still a little scary to walk on. At its highest point, the bridge is 175 meters off the ground. Far, far below     6    (be) the rushing river.

Arouca Geopark is well-known for its beautiful     7    (nature) scenery and the many outdoor activities that can     8    (do) there.

Now, the city of Arouca is hoping that the bridge will bring lots of tourists-and     9       (they) money-to the area. City leaders think the bridge could attract people     10     a lot of different reasons. Some might come for the scenery. Others might come to see the structure of the bridge. But perhaps most will come to enjoy the safe but scary experience of walking across.

In most Chinese tea villages, March is the time of year when locals start to pick and process tea. The     1     (usual) quiet villages suddenly become busy centers of activity, as people take out special tools and prepare     2     tea processing. In some villages, local people hold traditional ceremonies,     3     (thank) heaven for its blessing. The price of tea     4     (pick) in March is extremely high because it is fresh and contains multiple trace elements. China     5     (be) famous for tea production since ancient times. Of the goods transported and traded along     6     Old Silk Road linking China to the Middle East and Europe, the importance of tea     7     (match) only by silk. China produces Oolong, black, green, white, yellow and dark―also known as post-fermented (发酵). The Oolong, green and black     8    (vary)are most notable for their high quality. Most of China’s tea villages are found in remote    9     (mountain) areas in the south and southwest of the country,     10     the beautiful scenery is often hidden under clouds.

After over 2,100 days of operation, the central route of the South-North Water Diversion Project,     1     (transfer) 30 billion cubic meters of water and benefitted more than 67 million people up to now. The route,     2     (send) water from the Danjiangkou Reservoir located in the upper and middle reach of the Hanjiang River to Henan, Hebei, Tianjin and Beijing, stretches a total     3     (long) of 1,432 kilometers.

When the project just kicked off, only 20 of the 42 sections     4     (evaluate) in the Danjiangkou Reservoir and its upper reaches met water quality standard, and some even failed to meet Grade V standard,     5     lowest in China’s classification. After the operation of the project, all sections have met standard. The water fetched 15 meters below the surface in the project’s reservoirs is     6     (drink).

Since the project     7     (launch) in 2005, the water sources of the project have been well protected, and sound ecological environment has been maintained. At present, the forest coverage in Henan’s Nanyang and Hubei’s Shiyan,     8     the reservoirs locate, stands at 40.5 percent and 66.7 percent, respectively. The improved ecology also lifted biodiversity. These regions are home     9     170 migrant birds and a number of valuable plants. The improved environment has led to booming local tourism, attracting numerous visitors and constantly expanding the service industry for local communities. The enhanced ecological conservation efforts not only have no impacts on local people’s livelihood, but also     10     (steady) increase their income.

Tianjin is an important stop on one of the eight major bird-migration routes     1     North Asia to Australia, and many species rest in Beidagang’s coastal area before flying to Australia or New Zealand. The birds will return to Tianjin on their northward migrations that go as far     2     the North Pole. Beidagang Wetland     3    (cover) nearly 350 square kilometers, including an area of about 115 sq km, in the southeast of the Binhai New Area. The wetland is essential for the birds’ breeding and growth. “Without it, they may be in danger during their migrations,” experts say.

Beidagang Wetland Management Center deputy director Sun Baonian says they’ve made great efforts to improve rare — bird protection in recent years.     4     total of 1,347 Oriental storks have been identified in the wetlands,     5    (account) for nearly 45 percent of I he species’     6     (globe) migration population, he says. They prefer to nest in high trees and buildings. Since Beidagang doesn't have enough high trees, the center has set up 20 artificial nesting areas on poles, 13 of     7     have been used by the waterfowl (水禽). And 17 chicks were born in the wetlands late last year.

The center also offers “homes” for volunteers and tourists, who come to learn more about wetland protection and enhance their     8    (aware) about how to protect the wetlands and birds.

The project     9    (support) by the International Union for Conservation of Nature since 2012, following a high-level meeting in South Korea. In 2016, the IUCN encouraged China     10    (apply) for UNESCO status for the sites.

When you imagine the South Pole，what do you see？A pole with flags sticking out in an empty，frozen，white openness？Actually，there’s more than one South Pole—and none of them exactly fits the above     1     (describe).

If you think of the earth as a     2     (spin) basketball balanced on the tip of a finger，the place where the fingertip touches the ball is what     3     (call) the geographic South Pole.This South Pole is an imaginary point.There’s no pole with flags there，just a stick and a sign honoring the first explorers     4     (reach) the spot in 1911.

A short distance from the geographic South Pole is a ceremonial South Pole—    5     actual pole with flags from some countries.Far，far away is the magnetic South Pole—the South Pole     6     which a compass would point you.Its current location is 1,800 miles away from the geographic South Pole，in the Southern Ocean，so far north     7     it’s not even in the Antarctic circle.The ocean­going magnetic South Pole is     8     (natural) unmarked，but if you happen to be there，you     9     (notice)：Your compass needle moves aimlessly.

There is still another South Pole：the pole of inaccessibility，defined as the place in Antarctica that is the     10     (far) from any shore.

Jingdezhen porcelain(瓷器)is Chinese porcelain produced in or near Jingdezhen in southern China. Jingdezhen has produced porcelain     1     (century)ago. And the town     2    was named Jingdezhen by Emperor Zhenzong of the Northern Song Dynasty became a major kiln(窑)site around 1004.During the period, the     3    (produce)of porcelain in this area first became     4    (know).By the 14th century it had become the largest centre of producing Chinese porcelain, which remained in the following times. In the Ming Dynasty, official kilns in Jingdezhen     5    (control)by the emperor, making quality porcelain in large quantities for the emperor to give abroad as gifts. As a result, the town was     6    (close)linked to the world.

Although being a remote town in a hilly area, Jingdezhen is near the quality porcelain stone and forests which can provide plenty of wood for the kilns. It also has     7    river flowing from north to south,     8    (benefit)the transport of the fragile objects.

Jingdezhen has produced a great variety of     9     (value) porcelain. As a result, the town is famous     10     the “Porcelain Capital”. One type of its well-known high quality porcelain object is the blue and white porcelain from the 1330s.
