Li Daiyu and Liu Qian were on a trip to Canada.Before     1     (start) out，they spent a couple of days in Vancouver,     2     there were some shops selling crafts and antiques. And then they passed the Canadian Rockies by train.     3     (see) from the train window, the mountains and forests of Canada looked massive. After that they took the train to Lake Louise，where the blue water took their breath     4    . Their next stop was in Edmonton，a city with daily temperatures     5     (average) －10℃. They had known that Canada is a country which has vast lands but     6     small population. However，they didn’t anticipate     7     (see) such an open country.They were so     8     (amaze). The train thundered on，and the red maple trees outside the window     9     (confirm) that autumn had arrived in Canada. It was not until 9:30 a.m.     10     they finally reached their destination—Toronto. The whole journey took them four days.

As we all know, the Great Wall of China is one of the greatest     1     (sight) in the world---the longest wall in the world ,which     2     (consider) the symbol of China and the wisdom of Chinese people.

With     3    long history of more than 2300 years, the “Long Wall” was built in different areas by different dynasties     4     (protect) their territorial（领土的）borders. During the construction of the Great Wall, there were many     5     (interest) legends and stories, such as Meng Jiang Nü weeping over the Great Wall, a sad     6     romantic love story .

Today, the Great Wall has become a place     7     interest not only to the Chinese but also to people all over the world. Perhaps the most     8     (wide) famous advertising words in history come from the poetic pen of Chairman Mao: “He     9     has never been to the Great Wall is not a true man,” Actually, since the Great Wall was opened to the public, hundreds of millions of visitors     10     (be) to its various sections.

The city-state is usually a small, independent country     1    ( consist) of a single city, the government of which exercises full power within its borders. The single city of city-state functions as the center of political, economic, and     2     (culture) life.

Historically, the first recognized city-states developed     3    (gradual) in the classical period of Greek civilization during the 4th and 5th centuries BC. The Greek term for city-states, “polis”, came from the Acropolis,    4     served as the governmental center of ancient Athens. City-states became active again during the l1th century， when several Italian cities, such as Naples and Venice,     5    (realize) considerable economic boom.

The unique characteristic of a city-state that sets it aside from other     6    (type)   of governments is its independence. This means that a city-state has the full right and power to govern itself and     7     (it) citizens, without any interference (干涉) from outside governments. For example, the government of the city-state of Monaco, though    8    (locate) totally within France, is not subject to French laws or policies.

Unlike ancient city-states, modern city-states remain small in land areas. Lacking the space necessary for agriculture or industry, the economies of the three modern city-states depend    9     trade or tourism. Singapore, for example, has     10     second-busiest seaport in the world, and Monaco and Vatican City are two of the world's most popular tourist destinations.

The Cultural Landscape of Old Tea Forests of the Jingmai Mountain gained the World Heritage Site status,     1     (become) China’s 57th entry to the list and the first World Heritage Site related to tea. The newly named heritage site, located in Pu’er, Yunnan Province,     2     (consist) of five large scale old tea forests, three protective barrier forests and nine ancient villages     3     are mainly inhabited by Blang and Dai ethnic groups. According to the research, about 10% of the tea trees on the mountain are at     4     (little) 100 years old, with the oldest dating back more than 300 years.

The cultural landscape was     5     (joint) created by the ancestors of the Blang people, who immigrated to the Jingmai Mountain in the 10th century AD and later discovered wild tea trees and the native Dai people.     6     the basis of long standing practices, local people developed the understory growing technique, which involves allowing small and sufficiently shade tolerant trees     7     (grow) under the taller trees. They created ideal light conditions for growing tea trees, while preventing insect pests through a well-preserved forest ecosystem, thereby producing quality organic tea     8     (leaf) without the use of pesticides and chemical fertilizers.

The UNESCO World Heritage Committee noted the cultural landscape is     9     outstanding example of a human interaction with a challenging environment. It represents the ecological principles and wisdom which can inspire the     10     (sustain) development in the world today.
