2 . Chen Guanghui is a guardian for black-necked cranes(黑颈鹤) in the Dashanbao Black-necked Crane National Nature Reserve of Zhaotong city, in southwest China’s YunnanProvince. Whistling(吹口哨) is the secret language Chen uses to communicate with the black-necked cranes, a type of migratory bird under first class protection in China. She says different whistles signal different things. When she whistles in an increasing tone, she tries to tell the cranes: ask your companions to come back for lunch, and they would chirp(吱喳叫)to spread the message right away.

Living near the Dashanbao Nature Reserve, a major winter habitat(栖息地) for the rare species, Chen started to take care of them in 2003, a mission she took over from her mother, whose devotion dates back to the 1990s.

“In the first few days, I remembered they ran away as soon as I approached them. I was very upset and asked my mom to come back, and I was worried they would starve,”   says Chen. “I initially tried everything, even singing folk songs to attract them, but failed. Later, I used special whistles and gradually formed close bond with the cranes. ”

“I treat them as if they were my own children, and I’m always concerned about them, especially during snowy days when they can’t get food. I feel uncomfortable and anxious when I hear them chirp and usually rush to prepare corn for them. ” It’s never been an easy job, and Chen has sustained quite a few injuries over the years, even falling into frozen marsh(沼泽)while trying to save a trapped crane in 2008. However, she never gave up. With love and responsibility, she has persisted in caring for the cranes for about 20 years.

Thanks to the joint protection efforts of Chen and staff members at the nature reserve, now more than 1,900 black-necked cranes overwinter in the area each season every year, up from about 300 when the nature reserve was established.

7 . Tens of thousands of nature lovers see black bears and grizzly bears each year    1    But for the unfortunate few, bear encounters can lead to serious injury or death. If you come upon a bear in its natural setting, your first reaction may be to feel frightened. But staying safe depends on acting carefully and calmly.

    2    Some people would suggest running away, but bears can run much faster than humans can. Others say a person should drop to the ground and play dead.    3    It is best to be as educated as possible about different bear behaviors before you head into the wild.

If a bear is coming towards you, you must first determine if the bear attack is defensive（such as when protecting young bears）or predatory（捕食性的）（such as when hunting）.    4    Most grizzly bear attacks are defensive. When a bear is defensive, it is feeling threatened. Dropping to the ground is an effective way to show the bear that you are not a threat.

Black bears do not often challenge humans, but when they do, their attacks are usually predatory. Bears do not feel threatened when they are hunting, so playing dead will not help you stay safe. During a predatory bear attack, the first thing you should do is drop any food you have and back away. If the bear still comes towards you, make as much noise as possible by shouting and hitting objects.    5    . You can also use pepper spray（喷雾）during a bear attack. Always bring it with you in the wild, and have it ready to use without delay.

G．There are many ideas about how a person should react when faced with bears.

8 . Perhaps you know northern Americans still maintain the habit of celebrating Groundhog Day when a large groundhog (土拨鼠) checks to see its shadow on February 2 and helps to predict when winter will end. But have you ever heard about how a mountain town in North Carolina uses a caterpillar (毛毛虫) known as the Woolly Worm to make similar predictions?

According to the folklore (民间传说), the amount of black on the woolly worm in autumn predicts the severity of the upcoming winter. The longer the woolly worm’s black bands (带) are, the longer, colder, snowier, and more severe the winter will be. Similarly, a wider middle brown band is a sign of a milder upcoming winter. The position of the longest dark bands supposedly indicates which part of winter will be coldest or hardest. If the head end of the caterpillar is dark, the beginning of winter will be severe. If the tail end is dark, the end of winter will be cold. In addition, the caterpillar has 13 segments (昆虫的节/段) to its body, which traditional forecasters say correspond to the 13 weeks of winter.

Scientific studies on worm forecasting are rare. American Museum of Natural History entomologist Howard Curran conducted a small trial in 1948. Having heard about the caterpillar folklore, Curran headed to Bear Mountain State Park to collect caterpillars each fall for eight years. He found that if the worms had brown markings on more than a third of their body, winters tended to be milder.

Most scientists view the folklore of caterpillar predictions as just that, folklore. “It’s a wonderful story, but I do think it was a playful trial,” says Joe Boggs, an entomologist at Ohio State University Extension who has studied woolly worms. “Curran was a real scientist. He had tons of papers published, but he never published this one — probably because he knew it wouldn’t stand up to peer review.”

Mike Peters, an entomologist at the University of Massachusetts, doesn’t disagree, but he says there could be a link between the band of a caterpillar and the severity of winter. Peters suggests that the timing of their growth and environmental conditions, such as temperature, moisture levels, and food sources, can impact the appearance of woolly worms, including their size, coloration, and band patterns. By analyzing these characteristics, researchers can potentially infer information about the weather conditions. “The band does say something about a heavy winter,” he says. “The only thing is that it’s telling you about the previous year.”

1. How do people predict the weather through caterpillars?

A．By analyzing their living habits.

B．By measuring the change of their size.

C．By calculating the number of their segments.

D．By studying color bands on their bodies.

2. What is Howard Curran’s finding based on?

A．His personal observations.

B．An investigation on the locals.

C．Studies by previous scientists.

D．Statistics collected by the museum.

3. What is Joe Boggs’s attitude towards the folklore?

A．Positive.

B．Indifferent.

C．Doubtful.

D．Unclear.

4. Which statement might Mike Peters agree with?

A．The caterpillar forecasting needs long-term data to support it.

B．The color band of caterpillars can be a mirror of past weather.

C．The cold environment has a great impact on caterpillars’ growth.

D．The caterpillar can help predict the severity of winter accurately.

Braving the Waters

Joel Boyers and his wife Melody Among were heading home from the Nashville airport. Among had just earned her helicopter pilot’s licence when Boyers received a call from a stranger. The caller told him that her brother and his two daughters were trapped on their roof in Waverly, 60 miles from Nashville. They were surrounded by rising floodwaters caused by the heaviest rainfall that year.

Desperate, the caller begged, “Could you please, please rescue my loved ones?”

Boyers, 41, looked at the address the caller mentioned while glancing at the storm clouds. “Ma’am,” he said, “no one will fly in this weather ...” But even before he finished the sentence, Boyers knew they would go back up. “I’ve got a daughter myself,” Boyers says. “I’ll see what I can do.” He put the brother’s address into his phone and they drove back to the airport.

Before long they were in the air, unprepared for what they were about to see. It was nothing but raging water below them. There were two houses on fire. Cars in trees. Tons of debris (残骸). No one was going to be able to swim in that.

The flooding also took out cell phone service, meaning that Boyers couldn’t use his phone to pinpoint (精确定位) the house he was looking for. He flew on regardless.

As Boyers controlled the helicopter, Among began searching for people caught out on rooftops, bridges — anywhere they could land and get them on board. Suddenly, she saw a teenager trapped in a tree. The teen, soaking wet and exhausted, was barely out of the water. Since there was no place to land, Boyers lowered the helicopter until it approached to just above the water line. Among jumped out and swam to the tree, where she helped the teen into the helicopter. The teen was shaking and looking behind anxiously when she said, “Thank you so much, but my sister and uncle ... please help them ...”

Boyers dropped off the teen on a patch of land across the street. Then he and Among were back in the air.
