2 . Avebury is near the far more famous Stonehenge. What is interesting about it is that a village has grown up around the stones, unlike Stonehenge, which stands alone. Avebury and Stonehenge are just two of about 1,300 stone circles all over the UK. Many of them are in fantastic locations, like Castlering in Cumbria, from which you can see England’s highest mountain; and the Ring of Brodgar in the beautiful Orkney Island, off Scotland’s northern coast.
Some of them are UNESCO World Heritage sites, and several have local stories connected to them. For example, the Merry Maidens in West Cornwall is a group of nineteen stones. According to the story, they were young women — maidens — who were turned into stone for dancing on a Sunday.
Early historians thought that the stone circles were temples for the people who arrived in the UK in about 500 BC. Later research has shown that they are far older than that, at least 4,000 years old. Stonehenge could have been built 5,000 years ago, but it’s still nowhere near as old as the nearby wooden circle built about 10,000 years ago. Some experts believe they acted like calendars and have shown that some stones line up with sunrise or sunset on the longest and shortest days of the year. Others believe they were places for the dead bodies of the local rich and powerful.
We may never know why they were built, but each one leaves the visitor with a strong sense of the shortness of our existence in the sea of history. There are groups of stone circles and other prehistoric (史前的) monuments throughout the British Isles, so wherever you are staying you should include at least one in your tour.

3 . Chimney swift (烟囱雨燕) numbers have fallen by more than 70 percent since the 1960s, scientists believe, and by more than one-third over the past 16 years. That large drop have made the International Union for the Conversation of Nature regard chimney swifts as“vulnerable(脆弱的)”. That is the last step before they are considered “endangered”.
Chimney swift numbers are becoming smaller as the shape and design of the nation’s buildings change. People are tearing down old factory buildings and schools. Many of these buildings have chimneys. Today, most American homes do not have chimneys. And many homeowners who do have chimneys cover up the top to keep out.
People across the United States are putting up tall, narrow buildings to help chimney swifts. They hope they will use these buildings as nesting areas and resting places.
Bird lovers, Georgean and Paul Kyle, are often praised for starting the present interest in building towers. “It does give us hope that if we put them up, they will use them,” the Kyles said. They have put up more than 100 towers in Central Texas. Eighty percent of those buildings before the birds’ March arrival get nests in their first year. Hundreds of migrating swifts make use of the towers.
But the link between the drop in chimney swift numbers and chimney loss is not clear. The flying insects that swifts eat also appear to be dropping.
Professor Rubega thinks the cause of the birds’ drop could be in South America. “Chimney swifts are basically a South American bird that stays in North America for four months, ” she said. Rubega said a big problem is that scientists have only a few reports of small numbers of chimney swifts in the upper Amazon Basin. So, they do not really know where the little birds spend the winter, let alone what may be happening to them there.

4 . Biologists from Boise State University have been making noise in the forests of the western American state of Idaho. They are making noise to study the value of quiet in nature. They want to know how people and animals react to noise pollution.
The researchers placed outdoor speakers on the side of a half-kilometer-long part of a road in the Boise National Forest. For two years, they played the sounds of passing cars through the speakers. Professor Jesse says they found the sounds caused migratory （迁徙的）birds to flee. The birds also failed to gain weight.
Recently, researchers played sounds of machines that are used to remove natural gas from the ground. That sound is heard in natural gas fields throughout the American West. Professor Barber says these experiments are designed to help researchers learn the effects of noise pollution on birds, insects, bats, and people.
"We are testing the idea that these things are coupled -- that as the soundscape gets louder, wildlife suffers. But that also feeds back on to how much people get out of that experience, how much they value it, and thus how much they are willing to protect that same place."
The research team also studied a group of volunteers who watch birds for fun. Mitch Levenhagen is a graduate student in the research team. He measured how much the artificial noise lessened the ability of the birdwatchers to recognize recorded bird songs.
The birdwatchers said the artificial noise affected their ability to recognize bird sounds more than they thought it would. Birdwatcher Jim Lyons said the experiment caused him to value quiet more.
"I moved out of the city to a little place in the country where I wanted it to be quiet. I greatly value that. It is hard to find those places more and more. There are lots of ways to mitigate（减轻） sound. But it is trade-off. There is always a cost. And it comes down to people's values. What do we value more." said Volunteer Janice Engle.
1. What is the purpose of carrying out the research?| A．To prevent people making any noise in their daily life. |
| B．To find out the effect noise has on humans and animals. |
| C．To call on many more people to protect the environment. |
| D．To encourage people to keep quiet while they are in nature. |
| A．impressive | B．unique | C．instructive | D．convincing |
| A．The great importance of quiet in nature. |
| B．The big price humans will pay for health. |
| C．The great value of a sharp sense of hearing. |
| D．The necessity of protecting wildlife in nature. |
5 . It’s hard to imagine that just 25 years ago, Berlin was a city split (分开) into two by the Berlin Wall. I’ll never forget how people were excited as the Berlin Wall came down in 1989. Since then, Berlin has become one of the coolest cities in Europe. Here are the main reasons why I think Berlin is cool.
It’s affordable. Berlin has cheap hotels and everyday objects. You don’t have to worry about spending too much money when visiting Berlin.
It has fantastic festivals. Berlin knows how to give parties, and there is a festival here every month of the year. Perhaps the most famous is the Berlin International Film Festival.
It has great architecture (建筑设计). Berlin has beautiful architecture of its own. The Brandenburg Gate, built in the 18th century, is one of the city’ s most famous buildings, symbolizing more than 200 years of history. The TV Tower is as good as the Eiffel Tower in Paris and the London Eye.
The art scene is flourishing (繁荣). Berlin is a city of living art. Artists are allowed to create works of art on the sides of buildings.
If you want to visit an affordable European city with culture and lots of colors, Berlin is the place to be. What are you waiting for? Get to Europe’s coolest city before everyone else discovers it.

6 . In the United States，many teachers keep fish，hamsters(仓鼠)，and other animals in their classrooms.Teachers say students learn important lessons from the animals.More than 70 percent of teachers who have classroom pets say the animals help students learn responsibility.Research also shows that classroom pets can reduce stress.
“Pets can comfort kids who are having a bad day,”says Lisa Robbins，who works fora group called Pets in the Classroom.
But others think pets should be expelled from classrooms. In January，the Durango School District in Colorado began following a no-pet policy(政策).Now animals can be brought into Durango schools for certain lessons，but they can't stay.Officials were worried that animals might create problems for kids with allergies(过敏症).They were also concerned about the animals getting proper care.
Here's what two of our readers think.
Having classroom pets gives students a fun way to learn about animals. In my class last year，we had a class pet named Elliot.Our teacher also used him to teach us about different subjects.For example，in math，we calculated (计算)how much it costs to feed Elliot for a year.
Pets also help kids learn how to work as a team. My classmates and I took turns feeding Elliot and cleaning his tank,
If teachers are worried about students with allergies，they could get pets that don't have fur.
—D' Lasia Mays，Texas
Classroom pets can take away valuable class time.Some students might have a hard time focusing on the teacher when there are animals in the room.
Plus，having a classroom pet can cause safety problems. You never know how an animal will react to students.Even a cute little hamster might hurt a kid who sticks his or her hand in its cage.
—Patrick McKinney，Ohio

8 . A nation-wide honeybee crisis is under way in the United States. Lately bees have begun to rapidly disappear in24 states across the country. For reasons unknown, bees are flying off in search of nectar and pollen and simply never returning to their colonies.
Bees are extremely social insects; they never desert their young or bee queens. Researchers argue that bees are most probably dying during their search for nectar. A range of theories is also investigated, including a virus and poor bee nutrition. Researchers are looking into a group of pesticides that were banned in European countries to find out whether the chemical preparations(still used in the U. S.) are somehow causing damage to bees' born ability to find their way back home. According to yet another theory, the losses may have resulted from a massive attack by mites, which have repeatedly damaged bee colonies in the past.
The bees disappear as pressure has been building on the U. S. bee industry. The costs to maintain hives are continuously rising. The bee business becomes less profitable as a result. According to estimates by the Agriculture Department, the number of hives has dropped by a quarter over the last twenty years, and the number of beekeepers decreased by half. Beekeepers also have to deal with the problem of suburban spread as they search for areas where bees can hunt for nectar to stay healthy and feel good during the pollination season.
A terrible epidemic breaks out in The Plague, a novel by Albert Camus, shortly after hundreds of dead rats are discovered all over the town. The recent bee mystery, already nicknamed a "colony collapse disorder" by U. S researchers, seems to somewhat resemble the situation described in the novel. We can only hope that the "bee plague" will not take shape of a problem of global proportions.
