Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all ,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However ,they sing most of the time for a very different reason .Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal ,usually the male, claims(声称)as its own .Only he and his family are welcome there .No other families of the same species(物种)are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him .A bird does the same thing. But he expects an outsider almost any time ,especially at nesting(筑巢)season. So he is screaming all the time, whether he can see an outsider or not .This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language all their own. Most of it has to do with attracting mates and setting up territories.
56.Some scientists believe that most of the time birds’ singing is actually .

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

Wind , water, fire and ice-these powerful natural forces have shaped the land of America in the past. They are still changing it today.
The Colorado River slowly cut down through stone to make the Grand Canyon(大峡谷).
Long ago, ice sheets cut Yosemite Valley and the Great Lakes, and glaciers(冰川) are still on the move in Alaska.
Wind and rain storm hit the land from time to time. Fires sometimes burn down forests and destroy the homes of wild animals. This happened in Yellowstone Park in 1988.
Dead volcanic mountains such as Haleakala on Maui and Carter Lakein Oregon are beautiful to look at. But there are several active volcanoes in the US, especially along the Pacific Coast. There are also many earthquakes in this area. Scientists can do nothing to control earthquakes or volcanoes. This was shown clearly on May 18, 1980. At 8:32 that morning, Mount St Helens in Washington state broke out. The top of the mountain was blown off.
Over 60 people –campers, scientists, journalists, forest workers—were killed. Hundreds of square miles of forests were knocked down. In towns over 100 miles away, day suddenly became night. An ash cloud hid the sun for many hours. Towns and fields in Washington, Oregon, and Idaho were covered with dirty gray ash.
Scientists knew that Mt St Helens might erupt(爆发) soon. But no one could say when. And no one expected the terrible strength of the eruption. Many people were surprised and unready. Harry R. Truman, 84, owned a small hotel in Mt St Helens. Scientists had asked people to move away because the volcano was becoming dangerous.
But Harry Truman would not leave his home. Now it is covered with many feet of dirty ash. A small cross stands above the place where Harry probably died. Perhaps it is better that he did not see the destruction of Mt St Helens, the once beautiful lake, and the forests.
But slowly, life is returning to the dead area around the mountain. Grass and small plants are beginning to grow again. Deer and birds have been seen. The land will never be the same as it once was. Perhaps Mt St Helens will erupt again. But this is all part of nature’s pattern of change, and man has little power to control it.
