The Vikings, whose ancestors came from Scandinavia, were the first Europeans     1    (reach) America. They had lived in many places of northern Europe. In 982 AD, a man     2    (call) Eric the Red was forced to leave Iceland because of a murder, for     3    he got into trouble. Eric discovered Greenland and persuaded some people     4    (settle) in Greenland. Eric set sail again, but only half of the ships made     5    to Greenland this time.

Later a man, Biarni set sail from Iceland in search     6     Eris’s party. But he     7    (blow) off course and found himself in an unknown land, from where he     8    (eventual) reached Greenland.

In the year 1002, Leif, Eric the Red’s son, followed Biarni’s directions and sailed to     9    is believed to be the coast of present-day Canada. He also discovered Newfoundland. Actually, Eric the Red and Leif’s     10    (deed) are the first records we have of Europeans sailing to the Americas.

Peru     1     (lie) on the Pacific coast of South America with three main     2     (area): the land running along the coast, the Andes Mountains, and the Amazon rainforest. In the 1400s and 1500s, Peru was the centre of the     3     (power) ancient Inca Empire, whose emperor lived in the site Machu Picchu. In the 16th century, Spain took control     4     Peru. In Amazon Rainforest, you take     5     boat to reach your accommodation. Three days will witness the unique plants and animals there.     6     (walk) on the path through the Andes Mountains leads to Machu Picchu. You’ll     7     (amaze) by this destination.     8     (especial) amazing is the Incas’ dry stone method of building. Stones are cut in exact sizes     9     (hold) walls together other than the perfect fit. In Cusco, you must admire architecture. In Lake Titicaca, both the island     10     the local homes are made of water plants from the lake.

The United Kingdom consists of four countries: England, Wales, Scotland and Northern Ireland. Wales was linked     1     England in the 13th century. In the 17th century England and Wales were joined to Scotland,     2     (form) Great Britain.

They were united in     3     peaceful way. The southern part of Ireland was unwilling to join the English government and broke away to found its own government.

England is the     4     (large) of the four countries and for convenience it is divided     5     (rough) into three zones: the South of England, the Midlands and the North. Most of the population lives in the south, but most of the industrial cities     6     (locate) in the Midlands and the North. It is a pity that the industrial cities which were constructed in the nineteenth century do not attract     7     (visit).

London is the capital city with great historical treasures,     8     is the centre of national government and its administration. It has the oldest port, building and castle     9     (build) by the invaders. Without the historical evidence, we     10     (will) not be able to learn more about the history and culture of the UK.

In Hebei Province lies a vast forest called Saihanba. This green Great Wall,     1     at its peak during the Qing Dynasty covered thousands of hectares, had by the 1950s     2    （virtual）disappeared. This allowed sand to blow into Beijing from the northern deserts.

Saihanba is a combination of Chinese and Mongolian,     3    （mean）“beautiful highlands". Until the Qing Dynasty, it was a royal hunting land because of its cool summer weather and beautiful surroundings. However, most of the area had turned into a desert by the end of the Qing Dynasty.

In fact 56 years ago there was only one tree left. But without that tree, there     4    （be）no miracle of Saihanba today. In the early 1960s, over 350 foresters     5    （send）to this area to fight the desert. They were required     6    （rebuild）the forest in Saihanba. Few people, including the foresters themselves, believed they would succeed.

Their doubt disappeared, however, when they found the 200-year-old tree, swaying alone in     7     wind. If one tree could survive here,     8     could millions of trees, they thought.

After decades of hard work, three generations of the foresters have restored almost 80% of the original Saihanba forest. Recently, they were awarded the     9    （high）environmental honor from the United Nations for their great     10    （contribute）to creating a greener world.
