Christmas bird – watching is popular in the U.S.A. When the holiday season comes, some Americans are likely to watch and count birds in the sky with great interest every day. This activity began in the early part of the last century. It has a one-hundred-year history. At that time, there was a so-called “holiday hunting” custom. In order to celebrate the holiday, the hunters went out to kill birds and beasts. By 1900, there were 27 bird lovers who decided to count birds instead of killing birds. Since then, Christmas bird-watching was held every year. It has been continued to the present.

There were 42000 people who took part in the bird-watching last Christmas, from December 16 the year before to January 3 next year. They were in the United States and Canada, central America, south America and the Caribbean, watching and counting birds in the sky. The whole viewing area was divided into 1600 points. Each birdwatcher was responsible for 25 meters, and was required to write down the types and quantities of birds within 24 hours.

A birdwatcher described what he had watched vividly in his diary—“ When I looked up, I saw a beautiful ‘landscape’ in the sky: Red-crowned cranes(丹顶鹤) were driving up in cunning wedges that split the air. They were so neatly arranged, coordinating their movements. I was excited and breathtaking. Interestingly, the “human” shape(人字行) always maintains 110° ” .

“Why do red-crowned cranes choose to use ‘human’ shape when flying in formation?” He continued, “In my opinion, there are four reasons: first, the ‘human’ shape can make red-crowned cranes use increasing air which is produced by each other’s wings when they are swinging in the sky. It can increase the glide time and save physical ability. Second, the ‘human’ shape will enhance communication among the birds. The orders and the relevant information issued by the lead bird can be conveyed to each member in this migratory group unimpeded, accurately, rapidly and conveniently. Third, such a formation will help to find the birds left behind because of feeling run down as fast as possible, so that the young, the weak, the sick birds can get everyone’s help and encouragement. Finally, the ‘human’ shape shows not only beauty but also unity. It can give enemies a deterrent.They will be terrified and did not dare to attack the birds.The migration security of the birds will be ensured.”

Environmental experts admired and evaluated Christmas bird-watching highly. They pointed out that it made perfect sense. On the one hand it could enhance the human awareness of environmental protection. On the other hand it could provide first-hand information on birds.

To tweet, or not to tweet?

A guide to the social networking/ microblogging service Tewitter

SINCE its creation in 2006, Twitter, the social networking service, has taken cyber space by storm. At first glance it might seem like Facebook, but Twitter is in a league of its own, connecting people with fast-paced updates. It has become a place for activities, celebrities, businesses and everyday people to let others know about videos, opinions, interesting news, advertisements-and, yes what they are eating for lunch.

Twitter: n. a free social networking service that connects users through fast-paced status updates.

Twitter-er: n. one who uses Twitter.

Tweet: n. short updates or messages, of 140 characters or less, wh ich are posted on your profile and sent to your followers.

Retweet (RT): n. unofficial Twitter feature that indicates a re-posting of a tweet from another user. Often uses the text RT@username (of the original source) before the post.

Follower: n. one who receives another user’s updates on his or her Twitter profile.

Direct message: n. a private message sent from one Twitter-er to another.

The phenomenon includes a host of new vocabulary terms and concepts that every self-respecting Twitter-er should know. Here’s a quick course on Twitter.

So you’ve finally been swept up by the techno-tide and gotten a Twitter account. But what to write? Who knew 140 characters could be so overwhelming?

Darren Rowse of the TwiTip blog(www.twitip.com) recommends a two- step tweeting process: figure out what your follows want, and then give it to them. Some combination of cool links, conversation- starting quotes or questions , retweets and photos works well, Rowse writes.

Keep in mind that Twitter doesn’t directly offer photo hosting. You will need to use a third-party site like TwitPic (www.twitip.com) to upload your photos. Other sites, like TwitVid (tweetdeck.com/beta) can be used to post videos.

If you th ink the Twitter Web Site too complicated, try a Twiiter client—Tweetdeck(tweetdeck. Com/beta) and the Mac-only Tweetie(www. stebits. com)are popular, and both also are available as iPhone apps(应用程序).

Even without an iphone, you can update you Twitter on the go. After adding your phone number to your Twitter account, you can text updates to 40404(check Twitter’s Web site for numbers to use outside the United States)

But no matter how you tweet, remember that people can see what you post, and Twitter might not be the best place to complain about your boss, even if you make your Twitter private, your followers may not share your sense of discretion.

Twitter is crowded with celebrith accounts. The famous , who once avoided the media in their private lives, are posting everything on Twitter for all the cyber world to see, gathering followers in the millions. Who’s leading the celebrity pack? TwitterCounter(www.twittercounter.com), a site that tracks the most popular Twitter users, lists Ashton Kuntcher and former fashion model, as the nost popular Twitter-er with, as of our publication date, 2,691,112 followers.
