Macquarie Island was a beautiful place1its native inhabitants， including royal penguins， king penguins， and elephant seals， existed in harmony with their2（nature） habitat for thousands of years. However， in 1810， humans arrived on the island with rats and mice. They quickly took over3island， eating birds4（egg） and attacking baby birds. Cats were brought to control the rats and mice， but they also liked eating birds. Meanwhile， rabbits5（introduce） to the island but the exploding rabbit population provided food for cats， meaning that the number of cats also increased6（rapid）. This in turn led7more cats hunting birds. Although all the cats were caught in 2000， rats and mice8（explode） once again. Besides， the rabbits digging caused some land9（collapse） and killed many penguins. This incident made it clear that the rat， mouse and rabbit problem needed10（solve） once and for all. People are taking some steps to give the island a happy ending.

The horses， donkeys and dogs who arrive at Horse Creek Stable Rescue Sanctuary are often sick， weak or just tired. Lester Aradi， a retired police chief， along with his wife Diane， makes sure of their conservation. The refuge （收容所） for special needs animals they founded in Georgias Blue Ridge mountains is a 35-acre beacon of new beginnings. But there are endings here， too.

When they die， the animals are buried （埋葬） on a slight hillside overlooking the grassland. Graves （墳?zāi)梗?for dogs are lined up in a row. Burials for bigger animals—horses， donkeys—are marked with a fruit tree. Lester and Diane see it as a symbol of the circle of life. “We just try to honor them that way，” Lester said. But the most obvious marker for a fresh grave will be a three-legged dog named Tricycle. When an animal dies， he subsequently shows sadness—sometimes for as long as three days.

“I dont know if he can sense it， smell it， or whatever， but he looks sad. That is his way of saying goodbye.” He first looked like this when his friend Major died. “When Major died， we buried him here on the farm，” Lester said. “Tricycle went over and lay on his grave for about three days. He would come into the house. But every time he was outside， he would go to Majors grave and lie on it.”

Lester posted a picture of Tricycle mourning Major on Horse Creek Stable Rescue Sanctuarys Facebook page. Not long after that， a dog rescue group got in touch with him. They thought maybe Lester and Diane could take in another three-legged dog who needed a second chance in life. And so， Romeo arrived at the farm. Naturally， Tricycle bonded with his new friend， just like him. It is truly the circle of life.

1. What does the underlined word “it” in Paragraph 2 refer to？

A. Setting up graves in a row. B. Burying animals on the hillside.

C. Planting trees on the grassland. D. Using a tree to honor the dead animals.

2. What do we know about Tricycle？

A. He was healthy. B. He had no friends.

C. He could show his feelings. D. He disliked the house and left.

3. How did Romeo come to the refuge？

A. He was found by Tricycle. B. He was introduced by a group.

C. He got lost and came there. D. He was seen by Lester and Diane.

4. What can be a suitable title for the text？

If your family is thinking of getting a pet， consider adopting （領(lǐng)養(yǎng)） from an animal shelter， where all animals are in need of loving homes. 1 Here are some tips for you to find great animals.

Make some decisions.

Think about what you want in a pet and remember that all pets have different personalities. Cats tend to be more independent， but kittens need lots of attention. 2 However， they are usually great companions and love to spend time with their family.

Visit the shelter.

3 Remember that you may need to visit more than one shelter， or you may need to make more than one visit. Try to bring along everyone who will be living with the new pet. Ask the shelter staff lots of questions. And never adopt an animal because you feel sorry for it—be patient so you can find a pet who is truly a good match for your family.

4

Buy all necessary supplies and food well before the animal comes home. Make sure that the entire household is in agreement about rules and responsibilities—will the dog be allowed on the couch？ Who will clean the litter-box？ Put it in writing before the pet arrives.

Bring your new friend home！

Youll probably be excited when your new pet arrives， but be sure to give it space and time to get adjusted to a new home and a new family. 5 Interact with your pet a lot and get it used to a routine， and soon youll be one big happy family！

A. Get everything ready.

B. Put away the rubbish bins.

C. Dogs need to be walked at least twice a day.

D. Both cats and dogs are humans good partners.

E. The pet may act differently once they leave the shelter.

F. Set aside at least a few hours to visit shelters in your area.

G. Some may come with emotional issues， but most are happy， healthy.

A

Every year from March to October， Christian Moullec， also known as “Birdman”， takes his adapted light aircraft （輕型飛機(jī)） to the sky. However， the 58-year-old Frenchmans daily 30-minute flight is not just to enjoy the impressive views， but to guide flocks （鳥群） of lesser white-fronted geese through secure migration paths which the birds can teach future generations.

His deed （行動(dòng)） began in 1995 when he noticed the birds declining population in the wilds of Lapland， Sweden. To prevent their numbers from decreasing further， Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.

However， getting grown geese to follow his lead proved challenging. As young geese imitate （效仿） and follow whomever they view as their parent， Moullec decided to raise the geese from birth.

To help raise funds and heighten awareness of his job to protect not just the geese but birds worldwide， Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them， visitors， who come from as far as a 15-hour plane flight away， are treated to a variety of crane and goose species as well as breathtaking views of castles and cities.

He often brings his camera along for the flights， capturing photos not just for their beauty， but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds， with more than a third disappearing in the last 30 years. “Its a disaster，” he said. “My beautiful images with flying birds should be used to tell this story.”

1. Why does “Birdman” always fly to the sky on his aircraft？

A. To take visitors to operate his aircraft. B. To follow geese through safe paths.

C. To observe the migration of geese. D. To make geese fly safely.

2. What is “Birdman”？

A. A bird watcher. B. A bird hunter.

C. A nature lover. D. A volunteer pilot.

3. Why does Moullec often take photos on his flights？

A. To record the use of agricultural chemicals. B. To show damage caused by chemicals.

C. To describe his experiences with birds. D. To capture views of birds and cities.

4. What can be a suitable title for the text？

A. Birds Learning to Fly B. Birds Disappearing

C. Birdman Helps Flocks Migrate D. Birdman Protects Birds from Hunters

Plants are boring. They just sit there photosynthesizing （光合作用） while animals have all the fun. Right？ Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution started with ants feeding on plants and plants evolving ant-friendly features.

Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attacks from other insects and even mammals. These include hollow thorns （空心刺） that ants will live inside， or extra nectar （花蜜） on leaves for the ants to eat. Some ants will just take the nectar and run， but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around， by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away， eat the food packet， and leave the seed—often in a nutrient-rich area where itll grow better， and since its farther away from its parent， it wont have to compete for resources.

But scientists werent sure how the evolutionary relationship between ants and plants got started. It was a chicken-and-egg question， whether things started with ants developing behaviors to take advantage of plants， or plants evolving structures to take advantage of ants.

The history of ants and plants evolving together goes back to the time of the dinosaurs， and its not easy to tell from fossils who fired the first shot. However， it is a question of little significance. Scientists say their study matters because it provides a look at how these widespread and complex interactions evolved.

5. Why do some plants attach food packets to their seeds？

A. To reward the ants. B. To let the seeds move around.

C. To make a fool of ants. D. To provide nutrient for the seeds.

6. What does Paragraph 2 mainly tell us？

A. Why plants and ants need co-evolution. B. How plants and ants survive attacks.

C. What ants do to protect plants. D. How plants and ants interact.

7. What can we learn about the evolutionary relationship between ants and plants？

A. Ants depended more on plants. B. It was uncertain how it got started.

C. It caused a race for evolution. D. It was of little value for future studies.

8. What is the authors purpose of writing the text？

A. To introduce a research method. B. To inform us a latest research finding.

C. To raise our interest in science research. D. To discuss different views about plants.
