It is "one of the few bright spots in the Chinese economy," says Zeng Ming． He is talking about e-commerce． Mr Zeng, the chief strategy officer for Alibaba, a giant Chinese Internet firm, predicts that digital transactions on his firm's platforms will top l trillion yuan （$159 billion） this year-more than Amazon's and eBay's combined． That is a bold claim, but consider what happened on Singles Sunday．
Invented a few years ago by students and seized upon by digital marketers, this festival for lonely hearts falls annually on the llth day of the llth month （since l is the loneliest number）．It is like St Valentine's Day, only worse． Singletons shower each other with tender gifts: a barrage of pearls; a storm of sweets．
This November llth they spent a surprising 19 billion yuan on Alibaba's online platforms-a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday （the Monday after Thanksgiving, when retailers urge Americans to shop online）． About 100m purchases were logged, accounting for 80% of the packages shipped that day． Couriers（怏递员） were buried in parcels．
So life is good for China's e-tailers, then? Not exactly． The number of digital marketers is increasing and online sales are booming． Consumers are enjoying lower prices, better service and more variety． The problem? The pressure on profits in Chinese e-commerce is worse than in America, reckons Elinor Leung of CLSA, a broker． "Almost no one makes money," she says．
The fiercest battles are being fought between online retailers and their bricks-and-mortar（实体的） rivals．Dangdang, a firm． that resembles Amazon,．and 360buy, another online retailer, have cut prices fiercely． Tencent, a cash-rich online giant known for its instant-messaging software, is splashing out to win market share． 360buy has also just raised $400m from investors to do the same． But it is unclear how much longer such firms can burn through capital．

As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(发电)and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.
The 19 th century saw land grants(政府拨地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of the West, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns, which sprang up as railway stops and developed well, have lost their lifeblood and died.
Big solar plants and their power lines will also have effects far beyond their direct footprint in the West. This is not an argument against building them. We need alternative energy badly, and to really take advantage of it we need to be able to move electricity around far more readily than we can now.
So trade-offs will have to be made. Some scenic spots will be sacrificed. Some species(物种) will be forced to move, or will be carefully moved to special accommodations. Deals will be struck to reduce the immediate effects.
The lasting effects of these trade-offs are another matter. The 21st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that power and money to do a lot of good. But it is just as likely that they will be spent wastefully and will leave new problems behind, just like the railroads and the highways.
The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.

I had this exchange with my 6-year-old last week．
Him: Mom, we have to start buying Danimals．
Me: Why?
Him: So, I can bring it to |school for lunch．It's yogurt ．
Me: Why do you want it so badly?
Him: Because Danimals i|s giving away five fantastic Caribbean vacations．
I had to explain that there was little chance that he would win a vacation．It's a strategy used to encourage kids to beg for artificially-colored （人工着色的） yogurt that costs a lot．
Marketing follows my kids —and yours—wherever they go ．It comes via TV commercials． Store displays and websites are also constantly selling at our kids ．But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable．
Children can begin their day in character clothing．There's even character -themed wall paint available．A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste（牙膏）, character soap and shampoo, and a character wash cloth and towel ．Then, they can put on character clothing and character shoes．Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?
Surround kids with enough of the characters and they'll come to believe they need them．Most of us, of course, don't buy all those items．But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty （品牌忠诚）
At this time of year, parents buy licensed school supplies．With so much marketing around us, it can be to
ugh to stop the tide．
"One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ．"If you decide you want to buck this, it helps to find other people who will do the same thing ．That way, if your child says．"Everyone's doing it," you can really have a sense of whether everyone is．" |
