Traditional Chinese medicine (TCM) is a health care system in which patients     1     (treat) with natural plant, animal, and mineral remedies (药物). It is assumed, for a person to be healthy,     2     yin and yang forces should he in balance. Imbalance causes illness or injury. TCM is about     3     (restore) the balance between yin and yang forces in patients. It has been a major part of traditional Chinese culture and continues to play     4     vital role in medical treatment in China today.

According to the World Health Organization, nearly 80 percent of the world's population depends for its primary health care needs    5     medicines from plants and animals. This is especially true in countries where traditional medicines are     6     (wide) used.

Increasingly, however, modern medicines also contain substances from animals and plants. Given growing populations, increasing wealth, and the spreading    7     (popular) of natural remedies around the world, the demand for these medicines and remedies     8     (rise) now. The rising demand,     9     (combine) with reduced habitat, has caused an alarming increase in the number of plant and animal species used for medicinal purposes at risk for many years. For instance, TCM uses about 1,000 plant and 36 animal species, including the tiger, rhinoceros, and sea horse,     10     are all in danger.

In October 2021, China announced the opening of its Giant Panda National Park. Giant pandas are no longer classified as     1     endangered species but are still vulnerable (脆弱的), so conservationists are still working     2     (boost) their population numbers. By protecting pandas, the park also benefits another 8.000 animal and plant species living in the same ecosystem.

One creature     3     shares the same habit al with the giant panda is the red panda. While less famous than the giant panda, the red panda is just as cute—and     4     (unfortunate), endangered. Habitat loss caused by human activity     5     climate change is a major threat. While exact population numbers are unknown, researchers estimate that red pandas     6     (decline) by 50% in the last 18 years.

Another endangered animal living here is the clouded leopard (豹).     7     (large) than a house cat, clouded leopards are named for their irregular, cloud-like     8     (spot). The clouded leopard isn’t the only cat moving around the Giant Panda National Park. The snow leopard also shares the territory, although it’s rarely seen,     9     (make) it difficult for researchers to assess its population numbers. Snow leopards     10     (list) as vulnerable due to the increasing threats to their natural habitat.
