My husband and I enjoy seeing life through the eyes of our children. It’s amazing to watch as they discover their world.
While we were outdoors last summer enjoying the sunshine, our oldest daughter, Kaytlin, called me to the doorway. Beneath the steps was a baby red squirrel.
We watched it from a distance, not wanting to disturb it or scare off its mother. But after a long wait—and looking all around our house for signs of a nest or a mother—we realized the tiny squirrel was lost.
Shaking terribly, he was weak, thin, and hungry. We tried to find an expert to help, but the Inland Fisheries and Wildlife website showed that there were no wildlife experts in our area. After some quick research, we concluded that the best way to give the squirrel a fighting chance was to care for him ourselves. So a trip to the local store for milk and supplies was in order. More research taught us how much to feed him, how to estimate his age, how and when to wean (断奶) him, and that we should let him go as soon as he could survive on his own.
Our daughters and I took turns in feeding “Squirt.” Kaytlin took on the most responsibility. She taught him to eat from a bottle, and she woke in the night for his feeds.
To our relief, Squirt soon became healthy and strong. Within a few weeks he became more active. He would chatter (吱吱叫) for his next meal, playfully go around the girls, and lie down on them for sleep. It wasn’t long before he was weaned onto solid food and reintroduced to the wild.
His first few visits to the great outdoors were funny. Just like a child, he would play in the grass some and then run back to Kaytlin for safety. Soon she had him climbing trees and finding nest material.

There has been a very serious decline in the numbers of shallow-water fish as a result of overfishing. People still want to eat fish, so the fishing industry must look at other sources, especially the deep waters of the Atlantic.
Conservation measures will have to be put in place if these deep-sea fish are to survive. Research on five such species shows that numbers have declined by between 87 percent and 98 percent.
The problem is emphasized by the fact that the decline in numbers happened in less than twenty years. Deep-sea fish take a long time to reproduce and normally live for many years.
The damage done by overfishing goes beyond the sea environment. Millions of people make a living in the fishing industry.
| A．Billions of people rely on fish for protein. |
| B．Many people now choose not to eat deep-sea fish. |
| C．Unfortunately, their reproduction rate is very low. |
| D．This puts them in the category of “critically endangered”. |
| E．None of these facts has been taken into account by the fishing industry. |
| F．Overfishing is a major cause of decline in populations of ocean wildlife. |
| G．This has resulted in a sharp decline in the numbers of many of the species caught. |
4 . Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.
Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.
“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”
Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.
Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.
Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.
“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”

5 . For years, David James, who studies insects at Washington State University, had wanted to examine the migration (迁徙)patterns of West Coast monarch butterflies (黑脉金斑蝶). The route the butterflies travel has been hardly known because the populations are too small to follow. For every 200 monarchs tagged (打标签)by a researcher, only one is usually recovered at the end of its trip, James says, and finding even 200 in the wild to tag is unlikely. Knowing the route is vital to conservation efforts, but James had no way to figure it out- until he got a phone call from Washington State Penitentiary in Walla Walla.
The prison was looking for new activities to improve the mental health of those serving long-term sentences. So James began working with prisoners to raise monarchs through the whole process of their transformation. The adult insects were then tagged and released from the prison. Over five years, nearly 10, 000 monarchs flew from the facility. Elsewhere in Washington, Oregon and Idaho, researchers released another few thousand.
The tags included email addresses, and soon after the first butterflies took off, James started receiving messages from people who had spotted them. The butterflies, the reports confirmed, wintered in coastal California. Twelve of them landed at Lighthouse Field State Beach in Santa Cruz. Several more headed to Bolinas and Morro Bay.
The work helps researchers identify ideal places to plant milkweed and other vegetation that are important to the life cycle of West Coast monarch butterflies. It also brought out the gentler side of some of the prisoners. “They were very worried that they were going to harm the butterflies, ”James says. Watching the monarch change their form also touched the men. “This butterfly changed, ” James recalls prisoners telling him, “and maybe we can too. ”

6 . 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.

| A．It’s formal. | B．It’s risky. | C．It’s harmful. | D．It’s traditional. |
Last summer, Hilda worked as a volunteer with dolphin trainers at a sea life park. Her job was to make sure the tanks were free of any items so that the trainers could train the dolphins to fetch specific items. However, one day after cleaning, one of the dolphins, Maya, presented Hilda with a candy wrapper from the tank. When Katherine, the trainer, saw this, she blamed Hilda for her carelessness. Upset but not discouraged by this event, Hilda decided to do some spying on Maya.
The next morning, Hilda arrived at the park early. She put on her scuba gear (水下呼吸器) and jumped into the tank for her usual, underwater sweep. Finding nothing in the tank, she climbed out of the water just in time to see Katherine jumping in on the other side. After what happened yesterday, Hilda knew what she was doing. She watched as Katherine performed her underwater search, but Hilda wasn’t surprised when she surfaced empty-handed.
During the tank sweeps, Maya had been swimming playfully, but now the dolphin stopped suddenly and swam to the back part of the tank where the filter (过滤) box was located. She stuck her nose down behind the box and then swam away. What was Maya doing back there? Hilda wondered. She jumped back into the water and swam over to take a look behind the box, and her question was answered. Hilda then swam across the tank following Maya’s path and emerged from the water to find Katherine removing her scuba gear. As Katherine turned around, her mouth dropped open. There was Maya at the edge of the tank with a comb (梳子) in her mouth waiting for her treat.
“Maya! Where did you get that?” demanded Katherine, taking the comb and throwing her a fish. “I know where she got it,” declared Hilda climbing out of the tank with a handful of items still wet from their watery, resting place. “What’s all this?” Katherine asked, obviously confused.

10 . Parrots are prey animals, which means that other predators (捕食者) in the wild, such as hawks or snakes, are looking to make them into a meal. This one factor influences parrots’ behavior in your house more than any other.
Parrots are most easily hurt when feeding on the ground. Membership in a group plays an important function in ensuring their safety and improving their chances of survival from attacks by predators. The most common predators of parrots include hawks, snakes, cats, monkeys, and bats. Some predators make attacks only during the day while others hunt in the night.
As prey animals, parrots are constantly watching out for danger and they instinctively (本能地) react to risks. Their first choice is to take flight. However, if this is not possible, they will fight with their powerful beaks to defend themselves.
Because their biggest enemy is the hawk, parrots are especially reactive to quick movements from above and behind. For this reason, it is wise to avoid quick, sudden movements near your bird. This is a built-in reaction not subject to logic or reason. Simple and relatively harmless household objects can draw extreme fear responses from a bird. For example, a balloon may represent a hawk or a vacuum hose (吸尘器软管) may be the same as a snake in your bird’s mind.
As prey animals, parrots are often frightened by exposure to new household items or strangers. It is important to expose your bird to safe experiences and changes starting at a very young age to build flexibility and improve their adaptability. Variety in diet and toys, travel, and exposure to new people and places all help to make your bird more flexible and adaptable to change.
