Tiger research: Indonesia While sustainable tourism helps protect many of the Indonesia's wildlife, one of its rarest species, the Sumatran tiger, suffers as the island's cities expand into its forest habitat. Fortunately Biosphere Expeditions have created a trip that not only benefits the seriously endangered animal, but helps protect it too. Based in a remote camp in the heart of the rainforest, volunteers will be needed to tour the landscape, documenting tracks, kills and scats(粪便) to aid important research into the lives of these big cats. Company: Biosphere Expeditions  Length: 13 days More information: www. biosphere-expeditions. org

Cycling tour: Cambodia With an ancient world of temples and jungles, Cambodia is the kind of country that needs to be explored slowly. PEPY Tours offers 621 miles of green fields, dusty orange tracks and winding rivers on its 15-day cycling expeditions. Money goes directly to local people through homestays and lunches, while tours allow visitors to learn Khmer customs and contribute to ongoing community development projects.  Company: PEPY Tours Length: 15 days More information: www. pepytours. com

Beach stay: Tanzania A winner in the Best for Beach category at the Responsible Tourism Awards 2014, Chole Mjini Island is a tourists' paradise(天堂) located off the coast of Tanzania. With no roads or electricity, guests to the low-impact destination can enjoy a simple life in hand-built tree houses and spend days either stretched out on deserted beaches or searching for whale sharks. Company: Chole Mjini Island Length: 6 days More information: www. cholemjini. com

Teaching: Morocco It's the breathtaking beauty that draws tourists to Morocco's High Atlas Mountains, but while the remoteness of the setting may aid its charm it also causes problems. Few inhabitants of the region's rural villages, especially females, continue their education past primary school. Education For All (EFA) is a Moroccan NGO that builds and runs girls' boarding houses near secondary schools in the High Atlas, making further education theoretically possible. Based in the beautiful town of Asni, the programme is looking for female volunteers with teaching experience.

Aesha Ash is a ballet dancer who began The Swan Dreams Project in 2011. It is a program designed to bring ballet to girls of color in her community. Aesha Ash is one of the few women of color to ever grace the stages of the School of American Ballet in New York City. She wants to expose her community to more positive images of women of color through the use of ballet. She wants to show the world that beauty and grace are not defined by status or race. 

Aesha grew up in the inner city of Rochester, New York, where crime, gun violence and poverty were among the biggest threats to the community. For her, that's normal. That's just life in the neighborhood, but what she remembers most is the dance studio. She started dancing at the age of five. A teacher mentioned to her mother that she had some promise in ballet, and that it would be difficult for her, as a woman of color, to enter the ballet world. But the hardship she faced was the very thing that pushed her to pursue a career in ballet.

And there's so much negative stereotypes (刻板印象) and misunderstanding of who they are in the media. Through the use of imagery and her career as a ballet dancer, she challenges stereotypes that exist for women of color, particularly those from inner-city communities.

"It's important that our girls see that side of themselves because for many kids it's hard to be what you can't see. I hadn't seen a black ballet dancer before I decided that was what I wanted to be. It was really important for me to be in my environment displaying that because this is where I'm from. It was always beyond ballet," Aesha Ash stated.

1. （1） Why did Aesha start The Swan Dreams Project?

   A . To promote the images of females of color by ballet. B . To expose her community to a world of women of color. C . To grace the stages of the School of American Ballet. D . To show the world that beauty and grace are defined by status.
3. （2） Which of the following best describes the community she grew up in?

   A . Comfortable. B . Ancient. C . Peaceful. D . Unsafe.
5. （3） What can't we know from the passage?

   A . Aesha had a gift for ballet according to her teacher. B . The hardship Aesha faced was the color of her skin. C . Acsha wanted to be a ballet dancer because of a woman dancer of color. D . It is not easy to change the stereotypes that exist for women of color.
7. （4） What is the main idea of the text?

   A . A teacher provides chances for girls of color. B . A woman brings ballet to the girls of color. C . Ballet changes the life of a woman of color. D . A woman has changed the negative stereotypes.

Humans' ever spreading presence around the globe influences patterns of biological evolution in ways that we are just beginning to explore. On the Galápagos Islands, a body of evidence shows that the effect of our presence is increasing.

Luis F. De Leon from the University of Massachusetts Boston, together with other 6 scientists spent two years observing Darwin's finches (雀科小鸟) to evaluate our effects on their behavior. They started by conducting feeding observations on coexisting finch species at sites that ranged from non-urban areas to urban areas. They also employed finch-human interaction experiments to test whether and how finches respond to human presence. To measure whether finch feeding preferences varied with the degree of urbanization, "cafeteria" experiments were carried out — finches were presented with a selection of human and native food items.

The scientists found that Darwin's finches fed almost on human foods like rice and cookies or introduced garden species at urban locations. In contrast, at non-urban sites, finches fed mainly on native plant species and insects. Interaction tests suggest that urban birds get more accustomed to the presence of humans. Finally, at all sites of regular human presence, finches preferred human foods to natural foods.

The researchers warn that exploiting urban environments might present challenges for organisms (有机体), including shorter lifespans brought by the consumption of highly processed foods. Furthermore, the year-round availability of abundant human foods in urban environments might affect ecological and evolutionary processes that promoted species diversity. While the results clearly show a shift to human foods at urban sites, the adaptive significance of that shift is still an open question. 

These findings also suggest that human behavior is the main driver of finch preference for human foods. The researchers propose a possibility that the effect of human behavior is facilitated by our tendency to feed birds, directly or inadvertently via food dropping or littering. 

1. （1） How did the scientists carry out the study?

   A . By carrying out experiments in labs. B . By training finches and observing results C . By observing finches in different sites. D . By analyzing findings from previous experiments.
3. （2） Which is probably finches' favorite food at non-urban sites frequently visited by humans?

   A . Rice. B . An insect.

   C The leaves of a native plant.  D. The seed of an introduced plant. 

5. （3） What can we learn from the findings?

   A . All finches observed are willing to approach humans. B . Human food availability might lead to biodiversity loss. C . The reason for the shift of finch diets remains unknown. D . The more processed foods finches consume, the longer they live.
7. （4） What does the underlined word in paragraph 5 probably mean?

   A . Illegally. B . Voluntarily. C . Deliberately. D . Unintentionally.

It began in November 2016,when Hinton, then 17, got a text message from an 1 number inviting him to Thanks giving. When he asked who it was, the person responded:"Your grandma. "

"Grandma? Can I have your2 ?" the teenager replied. He received a photo of a woman he had never seen before. It was Dench，now 64.

Hinton wrote back,"You're not my grandma,"3 a laughing face. Still playing along, he jokingly asked:"Can I still get a4 though?"

Dench replied:"Of course you can. That's what grandmas do. Feed everyone. "Hinton soon realized her5 invitation had turned 6 , and he decided to take Dench up on her 7 . He went to her home in Mesa, Ariz. , about a 25-minute drive from his house south of Phoenix, for a Thanks giving meal with her family,including her actual grandson, whom she8 intended to text instead of Hinton.

Although Dench was13 about the misdirected text in 2016 at first, she said, both she and Hinton feel very14 that it happened. "Family is more than15 ," Dench said. "It's the people you want to be with. "

 A number of local people have been arrested for trying to stop trucks （load） with logs. 

 The hungry bear followed his nose to our camp，which (surround) by a high wire fence. 

 Peter, lifting his head, stared at the grandma with round, （astonish） eyes. 

 The scientist devoted himself(entire) to his research.
