Every year, millions of birds are killed or hurt when they fly into buildings. Why does this happen?
Many birds fly from one place to another. Most of the time, they live in the wild, such as forests and wetlands.
Some birds fly at night. They use the moon and stars to help guide them in the right direction. Tall buildings with lights on at night can confuse the birds.
| A．This is a big problem, especially on foggy and rainy nights. |
| B．People are trying to solve the problem. |
| C．These birds have no idea what glass is. |
| D．As a result, they fly right into the glass. |

【推荐1】Unknown to many Americans perhaps, the Japanese are huge fans of racing. They crowd racetracks throughout the country, especially near major cities like Tokyo. The country has some of the finest breeding farms and racehorses in the world.
Japanese racehorse and Japanese racing success has increased dramatically. While Japan is enjoying its new success in racing, it was not always or need not always be that way. The idea that effort is greater than outcome extends to horseracing. There is no finer example of this than the near-legendary story of Haru Urara, a horse whose name means “Glorious Spring”, but whose racing career was anything but glorious.
Haru Urara was born in 1996. Her father was NippoTeio, a highly successful racehorse whose wins included Tokyo’s famous horseracing competition of Yasuda Kinen, and whose mother was named Heroine. Her great-great-great grandfather was Canada’s famed Northern Dancer, considered the foundational sire of North American Thoroughbred racehorses.
Her owner NobutoBokulo tried to sell her when she was young and was surprisingly unsuccessful. So, with seemingly wonderful racing bloodlines, he trained her to race.
She started her racing career with a fifth-and last-place finish on Nov.17, 1998 at Kochi Racetrack on the Japanese island of Shikoku. Of course, it is not unusual for a new racehorse to finish poorly in a first outing. What followed, however, was definitely unusual.
An iron horse, Haru Urara raced as often as twice a month over the next four and a half years-and never won a single race. By 2003, her losing record totaled 80 and that is when her story was picked up by media in Japan and eventually around the world. People respected the fact that, while she never won, she ran with all her heart. The “Haru Urara Boom” as it came to be known touched even the most unrelated areas of Japanese life.

【推荐2】What is the kindest thing a pet has done for you? My dog gave her life to save my son. Cindy was the most home-loving and smart dog. When my son was born, she was immediately protective over him. She’d sit beside his bed for hours, popping her front legs up onto the bed every now and then to make sure he was OK.
My son was almost three years old. We lived near a busy road and we were super watchful at child going out of the front door—without exception.
One morning, around 4 a.m., our son somehow managed to “escape” through his bedroom window. Cindy knew that our son wasn’t allowed to go through the front door without us, evidenced by her pushing at him if he reached the front door handle. This day, she followed my son through the window.
At 5 a.m. the police woke us knocking on the door. Their words were—“your son was nearly killed but your dog noticed it”. They then recalled what the lorry (卡车) driver had said…
He told them that he was driving along in the dark and in the distance he could see something “light coloured” moving on the road. As he got closer, he could see a dog at the side of the road barking and barking at the “light coloured” something. At the last moment, he realized that this was a child and was about to swerve (转向). He said he could see the dog, still barking and glancing between the lorry and the child. While the driver was stopping the lorry, the dog ran out into the road, jumped at the child’s back and threw him out of the path of the lorry and at the same time, the lorry hit the dog.
The driver said that he’d never believe what he saw unless it was with his own eyes. The dog definitely knew the danger which was why she was barking so anxiously. She just saved that kid’s life and she knew what she was doing.
That was 39 years ago and I still miss Cindy every day. She was a rough collie (牧羊犬) and I can understand why this kind was chosen for the movies.

| C．the light coloured something was a dog | D．many movies were made for Cindy |
| A．Protective but stupid. | B．Daring and optimistic. |

【推荐3】Young male songbirds usually learn their songs from adult songbirds. But when those young birds don’t have older ones to teach them, they’re less likely to attract mates.
For five years, ecologist Ross Crates has studied the singing ability and mating success of birds called regent honeyeaters. These back and yellow birds were once common across Australia. But continuous loss of their living space since the 1950s has decreased their population to only about 300 or 400 wild birds today.
Male birds once formed large groups in winter. Now they’re spread out across the county, so many fly alone. That means fewer honeyeater adults are nearby during the young birds’ first year of life. Researchers found that a large number of male bids appear to be learning tunes only used by other species. About 12 percent of male regent honeyeaters end up producing versions of songs usually sung by friarbirds and black-faced cuckooshrikes. Scientists found that males who sang unusual songs were less triumphant in attracting mates.
Scott Ramsay is a behavioral ecologist. He said the songs were like an advertisement: “When male birds sing, it’s like putting out an ad saying, “I’m here … and I’m really interested in finding a partner.’”
Most male birds spend several months in their first year learning the songs they will sing for the rest of their lives. Some birds learn from their fathers. But regent honeyeaters leave the nest before they learn to sing, so the males need to find other birds to learn from.
Ecologist Carl Safina said, “We need to be aware of the importance of preserving song culture in birds … some elements of what these birds need to do to survive aren’t instinctive—they have to be learned.” To help young birds in reproduction programs learn their notes, Crates’ team have started playing male song recordings. They have also placed skilled male singers next to young learner. The hope is that these experienced birds can pass on their songs to the next generation.
1. What’s the cause of the declining regent honeyeater population?| A．Their sex imbalance. | B．Their shortening life cycle. |
| C．The decrease of their habitat. | D．The worsening atmospheric conditions. |
| A．absorbed | B．interested | C．confident | D．successful |
| A．Because they separate early. | B．Because they never live together. |
| C．Because they are generally too shy. | D．Because they learn singing after adulthood. |
| A．They’ve made their findings widely known. |
| B．They’ve begun putting their findings into action. |
| C．They’ve been finding mates for single male honeyeaters. |
| D．They’ve been recording the life details of male honeyeaters. |
