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 believed, for a person to be healthy,     2     yin and yang forces should be 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     7     (spread) popularity 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 put a 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 (犀牛), and sea horse,     10     are all in danger.

5 . I love everything about animals. Today, I went out for a simple walk to my library, when I _______________a dog! The dog looked like a German Shepard, and I, being an animal _______________, approached it. I noticed it had a _______________, but no leash. I tried asking multiple people around the dog if it _______________them, but everyone said no. I felt so bad, and didn’t know what to do. She was so friendly and sweet that I felt _______________about just leaving her there.

Then, what do you know? She started _______________me! I couldn’t help but smile at that. I was the only one who showed any _______________in her, petting her, talking to her, walking with her. So, together, we walked towards the _______________. I finally got a chance to _______________the number on her collar, but no one picked up! I was so ________________about this animal, and I was determined to not just leave it ________________around. I planned to head to a pet store.

However, before I even got to a store, a car ________________up in front of me with a father and two kids. It turns out that she was their dog, and had gotten ________________when the little boy opening their fence! They were so relieved to find her, and ________________me non-stop. I was relieved too! The dog ________________jumped into the car and I said goodbye to her.

7 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).

Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.

Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.

Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.

The fur trade kept nutria in check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.

Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.

Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She is trying to come up with a label to attach to nutria fashions to show it is eco-friendly.
