In Northwest China's Gansu Province     1     (lie) Zhangye National Geopark, which is blessed with a spectacular Danxia (red cloud) landform area     2     (cover) about 19 square miles. The Danxia landforms are     3     masterpiece of nature. The colorful mountain ridges are just like an overturned palette from heaven. Bands of fiery red, creamy orange, rich green and bright yellow streak across the mountain, forming     4     is known as the most beautiful rainbow mountain.

The incredible landscapes were created by sandstone and minerals piling on top of one another over the years due to tectonic plate movements. Wind, rain, and tine then carved the rock formations and rolling hills into     5     (vary) extraordinary shapes, including towers, pillars and valleys.

    6     (declare) a UNESCO World Heritage site in 2010 and a national geopark in 2011, the landform has become a top tourist     7     (attract). The park features a series of boardwalks that allow visitors to walk around the colorful sandstone landscapes. There are viewing platforms     8    (special) designed, enabling tourists to get close to the hills and feast their eyes     9     the magnificent sights without damaging the fragile ecosystem. Shuttle bus service is available, making     10     easy for tourists to get around the park.

3 . The Most Breathtaking Theaters in the World

The original Globe Theater was built by Shakespeare's company in 1599, but was destroyed by fire in 1613. A replica was built in 1997 just meters from the original site. The new 857-seat structure has several modern features. It has the first and only straw roof permitted in London since the great fire of 1666.

There can't be many theaters located in the middle of the Amazon rainforest, and the Teatro Amazonas is certainly the most breathtaking. The theater was built in 1895 and was designed by Italian architect Celestial Sacardim. Work took 15 years. largely thanks to the decision to source supplies from all over the world

The National Centre for the Performing Arts（NCPA）, built in 2007, is an arts centre in Beijing. Designed by French architect Paul Andreu, the NCPA is the largest theatre complex（建筑群）in Asia. The NCPA includes value in both ancient traditional Chinese architecture and modern architecture. It was specially designed to improve the red walls of ancient buildings and the Great Hall of the People in order to fit in with the surroundings.

My cousin and I took a trip by rail across Canada from west to east. Before starting out, we spent a couple of days in Vancouver, admiring the     1    (sight). Then we arose early to take the train to Lake Louise, passing through the Canadian Rockies.     2    (see) from the train window, the mountains and forests looked     3    (mass). We spent the night near the lake, where the blue water literally took our breath away,     4     headed to Jasper the next morning. The beautiful scenery convinced us it was the most awesome journey we     5    (take). From Jasper, we boarded the train bound     6     Toronto. One of our first stops was in Edmonton, which     7     (be) home to many shopping malls. We never anticipated seeing such an open country until the train headed across the Great Prairie.     8     amazed us most were a bunch of farms covering two wheat- growing provinces. The train thundered on, through the     9    (roll) hills in Ontario. It was     10    (true) enjoyable to watch the red maple leaves outside the window. After four days, we reached Toronto.

Originally constructed around 256 BCE by the State of Qin     1     an irrigation and flood control system, Dujiangyan is a remarkable example of ancient engineering skill and is still     2     use today.

During the Warring States period, people who lived along the banks of the Min River     3     (trouble) by annual flooding. Qin governor and irrigation engineer Li Bing investigated the problem thoroughly. He led a team     4     (construct) a levee(堤坝) to redirect a part of the river’s flow. Then they cut     5     channel through Mount Yulei to let the water flow through it. After the system was finished , no more floods     6     (occur). What’s more, it made Sichuan one of the most productive agricultural     7     (region) in China because the redirected water from the Min River could be used for irrigation. If you visit Dujiangyan, you will see an     8    (usual) construction that looks like a fish’s mouth. This famous attraction, Yuzui, together with two other important parts, namely, Feishayan and Baopingkou, was     9     (scientific) designed to control the water flow throughout the year.

    10     (recognize) as a UNESCO heritage site, Dujiangyan has irrigated farms while preventing floods for over 2,000 years.

The Honghe Hani Rice Terraces(梯田), in southern Yunnan, China, cover a huge 16, 603-hectare area. The terraces,     1    (know)to all of the world now, were made out of a thick forest by the Hani people. The terraces rise at different angles from a shallow 15°    2     a steep 75°, forming a wonderful landscape(景观)that     3    (be)rare in the world.

In 2003, the terraced fields were     4    (official)recognized by UNESCO as a World Cultural and Natural Heritage site. About 1,300 years ago, the Hani people first     5    (come)to the steep mountains. They struggled against the difficult terrain(地形), successfully creating the terraces, where they grew rice in order to make     6    (they) living. Over the past 1,300 years, the Hani people have developed a complex system of channels     7    (bring)water from the forested mountaintops. They show great appreciation for natural phenomena such as rivers, mountains, the sun, fire     8     the moon. They have also created a complete farming system     9     involves cattle, ducks, and fish and supports the     10    (produce)of red rice, the area's main crop.

The landscape changes through the year. In April the terraces are all green as rice starts to grow; in later parts of the year it is yellowish brown as the rice ripens. In February, the terraces become bare earth, with the water reflecting(反射)the sky.

7 . Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral reefs support more species per unit area than any other marine (海洋的) environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species living in and around reefs. This biodiversity is considered the key to finding new medicines for the 21st century. Many drugs are now being developed from coral reef animals and plants as possible cures for cancer, viruses, and other diseases.

Healthy coral reefs support fisheries as well as jobs and businesses through tourism and recreation. About half of all managed fisheries depend on coral reefs and related habitats for a part of their life cycles. The National Marine Fisheries Service estimates the commercial value of U. S. fisheries from coral reefs is over $ 100 million, Local economies receive billions of dollars from visitors to reefs through diving tours, recreational fishing trips, hotels, restaurants, and other businesses based near reef ecosystems.

Coral reef structures also buffer (缓冲) shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, and property damage. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms. Several million people live in U. S. coastal areas near coral reefs. Some coastal development is required to provide necessary infrastructure (基础设施) for coastal residents and the growing coastal tourism industry.

Despite their great economic and recreational value, coral reefs are severely threatened by pollution, disease, and habitat destruction. Once coral reefs are damaged, they are less able to support the many creatures that live on them and the communities near them. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.

The Xi’an City Wall is the most complete city wall that has survived China’s long history. It     1     (build) originally to protect the city     2     the Tang dynasty and has now been completely restored (修复). It is possible       3     (walk) or bike the entire 14 kilometers.

We accessed the wall through the South Gate. The wall is 12 meters high and from here you can see streams of people moving inside and outside the City Wall.

After     4     (spend) some time looking at all the defensive equipment at the wall, we decided it was time for some action and what     5     (good) than to ride on a piece of history!

We     6     (hire) our bikes from the rental place at the South Gate. My bike was old and shaky     7     did the job. It took us about 3 hours to go all     8     way around the Xi’an City Wall. Supposedly you can do it in two hours, but we stopped at the different gates and     9     (watchtower) to take pictures or just to watch the local people going about their     10     (day) routines.
