【推荐3】Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now the website BookCrossing.com turns the page on the traditional idea of a book group. Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure traveling far and wide with each new reader who finds it. Bruce Pederson, the managing director of Book Crossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

【推荐1】The United States has a vast network of National Parks spread all around the country. Here are some National Parks for you.

Arches National Park, Utah

More than 2,000 natural stone arches make Arches National Park a special place in Utah. Travelers from around the world come to see brilliant sunsets that light up the sky each night. Hikers and rock climbers will love the endless options for exploring, while more low-key visitors are sure to love the camping.

Acadia, Maine

Super close to Bar Harbor, one of Maine's most beloved tiny towns, Acadia National Park tops travel guides for the Vacation State. Before making your way to Mt. Desert island, dine on the country's most famous fish and lake advantage of the opportunity to go whale watching on the Atlantic Ocean. When visiting Acadia, set aside some time to hike and go boating.

Mount Rainier, Washington

We couldn't leave the park with you slowly moving ice off the list. Washington's Mount Rainier National Park, found southeast of Seattle, has 25 of them (along with the famous volcano) as its attention-catching sight. The National Park says it's "the snowiest place on earth where snow is measured regularly." If snowcapped peaks aren't your thing, plan to visit the park when the weather is warmer.

Great Sand Dunes (沙丘), Colorado

You probably imagine the Rocky Mountains when you think about Colorado, but did you know that the Centennial state is also home to the United States' largest sand dunes? See them for yourself at Great Sand Dunes National Park, where you can go sand boarding or "fat biking". Though June temperatures are said to be some of Southern Colorado's best, a warm winter day can be an equally enjoyable time to see the dunes.

【推荐3】Most people feel that dreams are unique to humans, but many dog owners will likely disagree. They have noticed that their dogs at various times during the sleep may shake legs, snort(哼)and sometimes growl (低声吼叫)which gives the impression that they are dreaming. These things may wonder us about whether dogs dream.

Scientists confirm that dogs probably do dream. It turns out that dog brains and human brains have many similarities during sleep cycles. Researchers used special machines to measure electrical activity in a dog’s brain and a human’s brain. Scientists already knew that when humans dream, a certain part of the brain is active during sleep. Researchers discovered that the same part of the brain is active in sleeping dogs. Scientists have other data that back up these findings.

Many people dream that they are trying to move but cannot. Interestingly, part of that experience is not a dream. When people sleep, the brain produces a chemical that causes the dreamer to become temporarily paralyzed(使麻痹). Researchers think this happens so that people cannot physically act out dreams while they are sleeping. Dog brains make the same chemical. In one study during which this chemical was blocked, sleeping test dogs performed physical activities, such as standing up, sniffing around the room for imaginary rabbits, or chasing (追逐)imaginary balls.

Because of these similarities, researchers believe that the content of a dogs dream might come from the same source as a human’s dream. “People’s dreams are usually based on things they did that day, ” says Dr. Samantha Hudspith. “So we have reasons to believe that dogs dream about the things theyve done that day. Of course, there will never be a way to prove this. Dogs cannot describe their dreams the way that humans can. ”
