Going to Mount Huangshan reminds me of the popular Beatles’ song “The Long and Winding Road”.     1     is so breathtaking about the experience is the out-of-this-world scenes. The rolling sea of clouds you see once you are at the top will remind you how tiny we     2     (human) are.

The hot spring at the foot of the mountain is something you must try after the climb. It will     3    (undoubted) help you get refreshed! The amazing thing about the spring is that the colder the temperature gets, the     4     (hot) the spring! Strange, isn’t it? But that’s how nature is — always leaving us     5     (astonish).

What comes next is the endless series of steps. You can’t help wondering how hard it     6     (be) for the people then to put all those rocks into place. Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure     7    offers a place where you can sit down to rest your     8     (ache) legs.

As the song goes, this long and winding road “will never disappear”, and it will always stick in the visitor’s memory. It sure does in     9     (I). While you’re in China, Mount Huangshan is     10     must to visit!

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.

Shennongjia is a household name in China because it’s the home of the legendary “wild man”. Its folk tale spans the generations.

Between 1976 and 1981, the Chinese Academy of Sciences organized three large scale     1       (science) investigations. They have collected hair, footprints and waste suspected of belonging     2     a “wild man”, but some experts argue that most were the result of bears, monkeys or even human beings. They failed     3     (uncover) the myth of “wild man”, but discovered the area’s rich biodiversity. Although several hundred people have claimed     4     (they) as eyewitnesses of some giant apelike creatures in Shennongjia, there is no tangible evidence to confirm the     5     (exist) of a “wild man”.

Nowadays, Shennongjia’s attraction is not merely about “wild man”. Its appeal     6     (be) more about its lively ecology, rich biodiversity and karst landforms. Shennongjia’s beauty varies over the year as nature     7     (take) its course. Tourists can enjoy flower blossoms in spring, be shaded from the summer heat, appreciate red leaves in autumn     8     go skiing in winter.

The “wild man” legend has been passed on for generations by word-of- mouth. In 2016, the legend of "wild man" in Shennongjia     9     (add) to Hubei province’s intangible cultural heritage list. Today, tourists can visit Wild Man Cave,     10     eyewitnesses claimed that they spotted the creatures, and see “wild man” sculptures.

The classical gardens of Suzhou, Jiangsu province, date back to the 6th century     1     the city was founded     2     the capital of the Wu Kingdom. Today, more than 50 of these gardens are still in     3     (exist), nine of which are regarded as the finest embodiments (化身) of Chinese “Mountain and Water” gardens.

Built in the 11th century on the site of an     4     (early) destroyed garden, Canglang Pavilion has the longest history among all the existing classical gardens in Suzhou. Naturally     5     (lay) out and well designed, it is called one of the four best gardens in Suzhou. The garden looks simple but natural. Without complex     6     (decorate), it combines buildings with scenery so well     7     the whole garden appears to be naturally endowed (赋予). Since many of the     8     (origin) features of the garden have been preserved, the garden has a high historical and artistic value.

The classical gardens of Suzhou     9     (be) the most vivid specimens(样本)of culture from the East Yangtze Delta region in the 11th to 19th centuries. The underlying philosophy, literature, art, and craftsmanship     10     (show) in the architecture, gardening as well as the handcrafts perfectly reflect the monumental achievements of the social, cultural, scientific, and technological developments of this period.

10 . When you swim on the beach and sea, have you ever accidentally drunk the seawater? How did it feel? It must have tasted salty. So, why is the seawater salty?

Seawater is water that comes from the ocean. Seawater can be salty because it contains an average salt content of 3.5%. This is also a place for the salt farmers to produce cooking salt and other salt.

Some theories explain that seawater comes from rainwater that falls and flows through rivers and estuaries (河口) where the seawater will be fully filled and again formed clouds because the steam uses the help of the sun. When we talk about this, we talk about the rainwater cycle. But when the rainwater cycle occurs, the water that passes through the river carries mineral salts. These mineral salts are obtained from various places of the land starting from rocks and soils that the rainwater flows through, these remaining mineral salts make seawater salty, so the salinity of seawater is different in each part of the world. But it is certain that seawater is salty or has high salinity.

The saltiest sea in the world is the Red Sea. There the temperature is extremely hot so that evaporation (蒸发) is greatly carried out. High evaporation, coupled with little rainfall and little input of water from the river, causes its highest level of salinity. There is also the Dead Sea, which is nine times saltier. Due to the high salinity, when you swim there, you can float. However, the Dead Sea is not a sea at all which is a lake geographically.
