Birds in cities are damaging their health by trying to sing above the noise of urban life.
New research shows that male birds are trying to compete against traffic and city sounds.They are now singing louder and at higher frequencies,which could harm their vocal cords.Some birds are choosing to sing at night instead of dudng the day.This makes them more open to attack and also creates stress and exhanstion.
“The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate.This could lead to inbreeding and a weak gene pool.”said Dr Sue Anne Zollinger of the University of St Andrews.
According to Zollingar,a bird group with a small geae pool might adapt less quickly to new diseases and could be wiped out.
A study of the dawn chorus found that birds in Berlin sang up to 14 decibels(分贝)louder than those in the forest.The birds sang loudest on weekday momings.
“By trying to sing over the sound of the city,birds are rising vocal injury,”said Zollinger.“All this puts the sarne strain on a bird’s vocal cords as when ahuman need to shout to be heard—except the birds are doing it all day,every day,”she said.
“Singing under such pressure means birds have less control over the sound they produce. Their songs may lose quality and become more rough—sounding.”said Zollinger.This could make them appear less attractive to female birds.
Mark Constantine,author of The Sound Approach to Birding,said:“Birdsong is important for our quality of life and has been proved to reduce our blood pressure.When we live in the centre of large,urban areas,we get stressed and it's extremely good to have birdsong around us.The impact on humans of birdsong is massive.It harms us,as well as the birds,if their songs become louder and simpler
53.Some birds in cities now choose to sing at night time because_______.
A.they want to attract more birds of opposite sex
B.they are more likely to be discovered by their family
C.they can’t adapt to the loud noises during the daytime
D.they have to frighten their enemy away
54.According to the passage,urban and rural birds might not be able to_______.
A.recognize each other
B communicate with each other
C live with each other
D.compete against each other
55.It requires greatest efforts for birds in cities to sing o_______.
A.Monday nights B.Wednesday afternoons
C.Saturday Evenings D.Friday momings
56.According to Dr Sue Anne Zollinger,birds singing louder might eventually lead to_______.
A.the harm done to man’s health
B the dying out of a species
C.the serious damage to the bird’s vocal cords
D.the decrease ofthe birth rate ofa bird group

In Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections(注射)so that they won't carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food.

The Great Fire of London started in the very early hours of September 2, 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. Over one hundred people became homeless, but only a few lost their lives .
The fire started on Sunday morning in the house of the King’s baker(面包师)in Pudding Lane. The baker, with his wife and family, was able to get out through a window into the roof. A strong wind blew the fire from the bakery(面包房)into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o’clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul’s and the Guildhall among them .
Samuel Pepys , the famous writer, writer about the fire, “People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat .”
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path(路径) of the fire.With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect(建筑师), wanted a city with wider streets and fine new houses of stone.In fact, the streets are still narrow, but he did build more than fifty churches, among which was the new St Paul’s
The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.

A boy and a girl were a couple of lovers. The girl liked feeling rain, so the boy was always holding the umbrella when it rained and most part of the umbrella was over the girl. Rain showered the boy every time but he said nothing except looked at the gift's face, which was full of silent satisfaction. He felt very happy, so did the girl.
One day they went out for a walk. They were walking hand in hand passing a building which was under construction. The girl jumped with excitement and said something. The boy seldom talked only feeling excited as she felt looking at her silently. When the girl was talking, a not big or small stone fell down from the building toward the girl's head! At that moment the boy took the girl in his arms so suddenly and so strongly that the girl let out a scream. He meant to protect the gift with his body. But the boy turned over to make his own body downward before they dropped on the ground. As a result, only the girl's hand was smashed by the stone and fractured.
The girl came back to earth and cried with pain, tears weeping up. She thought the saying that “The husband and the wife are birds in the same forest essentially, but when serious tragedy comes, they will fly separately” was really not wrong! With this, she straggled and stood up from. the boy's body keeping from the pains and slowly ran away without glancing at the boy.
At the time, the boy was calling the girl's name in a weak voice, his lips were already white. He took out his mobile phone and dialed the girl's number, but the girl didn't answer. He dialed again she didn't answer again. For several times, he gave up. But his fingers pressed something on the mobile. At that time, beside the boy, the blood spread slowly, his hand hung and the mobile phone lay in the blood, he had no strength to press the “SENT” key yet.
The next day, when the girl heard of the news that the boy was being rescued, she ran to the hospital without considering her anger. When she hurried to the hospital, the doctor had already declared his death; the cause of his death was that his lung had lost too much blood.
It was because, when the boy meant to protect the girl with his body he found that there was a steel stick under them, so he turned over to make it inset(=put into) his own body.
The boy's mother passed the boy's mobile phone on to the gift.
The girl read the message that hadn't been sent: “Honey, I'm sorry, I still couldn't protect you and made you wound... “Upon this, the girl couldn't help crying...

Birds that are half-asleep — with one brain hemisphere (半球) alert(警觉) and the other sleeping — control which side of the brain remains awake, according to a new study of sleeping ducks.
Earlier studies have recorded half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.
Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze(注视) direction.
Also, birds napping (打盹) at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in inner spots, outer birds half-asleep during some 32 percent of napping time.
“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say.
The results provide the best evidence for a long-standing assumption that single-hemisphere sleep developed over time as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.
Useful as half-sleeping might be, it’s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.
Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg.” He supposes that more examples may turn up when we take a closer look at other species.
1.According to the passage, birds often half sleep because ______.
A. they have to watch out for possible attacks
B. their brain hemispheres take turns to rest
C. the two halves of their brain are differently organized
D. they have to constantly keep an eye on their companions
2.What is implied about the example of a bird’s sleeping in front of a mirror?
A. An imagined companion gives the bird a sense of security.
B. Birds prefer to sleep in pairs for the sake of their security.
C. The phenomenon of birds napping in pairs is widespread.
D. A single pet bird enjoys seeing its own reflection in the mirror.
3.It can be inferred that _______.
A. Birds never sleep with both hemispheres resting at once.
B. Inner ducks depend on single-hemisphere sleep, rather than total relaxation, as often as birds napping at the end of the line do
C. It is not the first time for scientists to research on birds’ half-brain sleep
D. Birds hardly sleep without a companion
4.By saying “just the tip of the iceberg”, Siegel suggests that _______.
A. half-brain sleep has something to do with icy weather
B. the mystery of half-brain sleep is close to being solved
C. most birds living in cold regions tend to be half sleepers
D. half-brain sleep may exist among other species
