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 . 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.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号中单词的正确形式。

The average temperature of the Earth’s surface has increase by 0.85°C in the last hundred years. It’s too late to reverse the changes. Now we have to find ways     1     (adapt) to extreme weather, rising sea levels, and melting polar ice caps.

However, we can reduce greenhouse gas missions or make     2     (they) less harmful. An Argentinian company has started collecting cow emissions and changing them     3     usable energy. As the world eats more meal, methane(沼气)

emissions from animals are     4     (actual) becoming a bigger climate concern. And one day’s worth of cow emissions     5     (provide) energy to run a car for 24 hours.

And rich countries have the resources to adapt to     6     (globe) warming, while poorer countries don’t. Saleemul Hug director of the International Center for Climate Change and Development in Bangladesh, said that the rich countries had promised a hundred billion dollars a year,     7     (start) from 2020, to cover all kinds of climate change activities.

And countries where lack of water is a problem like Australia, China, and Spain, have built plants,     8     remove the salt from sea water to produce drinking water. But     9     is too expensive for developing countries to do this, even though they need them. So in relative terms, one billion dollars a year to help poor countries is a small sum of money when     10     (compare) to their need.

5 . Manta rays (魔鬼鱼)are some of the creatures in the ocean who allow divers to swim right up to and interact (互动) with them. Unfortunately, these gentle animals are in big trouble. Since 2011, manta rays have been listed as a threatened species worldwide.

Peru, a country in South America, recently took a big step to protect giant manta rays: It banned fishing for them. Although 12 other countries have passed laws to protect rays, Peru's may be the most important one yet. That's because there are more manta rays in the Pacific Ocean near Peru than in any other place in the world.

Giant manta rays are unusual — looking creatures. The giant, flat rays are typically about 4.5 meters wide and can grow up to 8 meters wide! "They're" sort of like giant flying carpets underwater, says Joshua Stewart of the Manta Trust, an organization that researches manta rays.

People catch rays for their meal. Overfishing is bad for any sea creature, but it's even worse for manta rays. Female manta rays usually have only one baby every two to five years. So every ray that's caught hurts the population in a big way. People who break Peru's new law can be fined or have their fishing licenses taken away. Even rays caught accidentally in fishing nets must be set free.

Earlier this year, the Manta Trust attached video cameras, called Crittercams, to manta rays off the west coast of Mexico. The footage(连续镜头)the cameras collect could help researchers predict where rays swim and when. The scientists could use the information to warn fishing boats to avoid these areas, helping reduce the number of accidentally caught rays.

Stewart says it's important to protect these unique creatures. "There's really no other animal that compares in size and that you can have interactions with in the wild.
