Iceland is a land of volcanoes. Nowhere is 【小题1】 (evident) than on the West man Islands off the southern coast of Iceland. Here, 【小题2】(century) of volcanic eruptions formed many eye-catching sea cliffs (悬崖), among【小题3】 one stands out: A part of the volcano-formed coast on Heaney looks exactly like the head of a large elephant【小题4】(stick) its trunk in the water.

In fact, it looks so much like an elephant that many people think it must have been shaped by humans. That is not 【小题5】 case, however. The elephant’s realistic 【小题6】(appear) is, at least partially, due to the fact that the cliff【小题7】(consist) of a special rock. The rock gives the figure “skin” that looks wrinkled and gray, just like that of a real elephant.

The most common theory is that the rock formations came from the Endwell Volcano, which【小题8】 (erupt) many times since the 1940s.

In spite of the strong resemblance to an elephant, some people 【小题9】(actual) see something different when they look at the rock formation. They see the fictional character Cthulhu, a sea beast.

Whether you see an elephant 【小题10】 a fictional beast, as one of many attractions on Heaney, the rock does draw curious sightseers.

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

Saihanba is a combination of Chinese and Mongolian, 【小题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 【小题4】（be）no miracle of Saihanba today. In the early 1960s, over 350 foresters 【小题5】（send）to this area to fight the desert. They were required 【小题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 【小题7】 wind. If one tree could survive here, 【小题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 【小题9】（high）environmental honor from the United Nations for their great 【小题10】（contribute）to creating a greener world.

A new record-high number of black-necked cranes, a species under first-class state 【小题1】 (protect) in Southwest China’s Yunnan province 【小题2】(monitor) during the wintering period, since the Yunnan Dashanbao National Nature Reserve was established in 1990. The 【小题3】 (high) number of 2, 260 migratory black-necked cranes has been spotted. The rare cranes begin their wintering at the reserve around Oct. 31 every year. 【小题4】 total number of overwintering black-necked cranes in the reserve reached 1, 926 in 2021.

The reserve, 【小题5】 (locate) in the Zhaoyang district of Zhaotong city, is the most significant wintering habitat 【小题6】 transfer station for migratory black-necked cranes on the Yunnan-Guizhou Plateau. It also boasts China’s largest quantity distribution per unit area of the species.

Over recent years, the reserve has made a determined effort 【小题7】 (implement) conservation measures, such 【小题8】 wetland protection and restoration, and the construction of food source bases, 【小题9】 will steadily improve its ecological environment for migratory birds.

During the past three years, an average of over 1, 500 black-necked cranes were spotted arriving at the reserve for wintering, while the numbers of 【小题10】 migratory birds were also on the rise thanks to these local conservation efforts.
