Article: Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust , eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones. Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago. "It's a fantastic case of solving a jigsaw puzzle ,"says one of the researchers. He notes that the puzzle was "a very difficult one because these rocks are all very old and have been badly ruined".

Article: It's really a tough job for automakers doing marketing and sales in China, where competition is acute and customers have little loyalty. They have tried a range of tricks in recent years. But there should be a moral bottom line. Unfortunately, a Buick dealership used the tragedy of a two-month-old infant to advertise its cars last week on Weibo - Micro blog. And Hyundai Motor followed suit. On March 4, an SUV was stolen with the infant left inside alone in the northeastern city of Changchun. The news spread widely on Weibo after the baby's father called the local police and radio station for help. The next day it was revealed that the infant was choked to death and buried in snow by the thief. The online community expressed its deeply felt sympathy and condolences. The Buick dealership posted a photo of the baby and two of its cars on its official Weibo account to advertise its GPS system that can locate the stolen car. "A few thoughts on the Changchun stolen car and baby incident: when buying a car it's entirely OK to choose a brand with advanced technology," said the post. Though the post was made before tragic fate of the infant was known, the action generated a storm of outrage on Weibo. Some online commentators said it is "marketing at the cost of lives" and "extremely _ ." Worse was the post on Hyundai's official Weibo account that advertised the anti - theft system on its new SUV Santa Fe, an entry made after the child was known to have died. The action also enraged micro bloggers. Both posts were soon deleted. The Buick dealership made an apology on Weibo to the family of the victim and the public. But screenshots saved by users continued to be posted and the negative impact on both brands persists. The two brands probably didn't expect such a firestorm of fury from the Internet community, but they really made a big mistake sinking below the moral bottom line. They certainly ruined their own brand images. The Chinese have the same proverb as the English language - a little leak will sink a great ship. It takes decades to build the great ship of a respectable brand but it can take just a moment of negligence to make it fail completely. For those in corporate marketing, two lessons should be learned: first, be careful in the era of social media when one wrong can be easily magnified and have disastrous impacts in just a few clicks. Second and more importantly, think with your brain and heart. Never break the moral bonds of respect for human life and sympathy for our fellow man.

Article: In Britain arrangements for inviting and entertaining guests at a wedding are usually the responsibility of the bride's family.In most cases it is mainly friends and relations of both families who are invited but when bride's father is a businessman of some kind, the wedding reception may provide a useful occasion for establishing social connections with clients or customers and other people whose goodwill may be of advantage to him.it is, however, the bride's mother who has the job of sending out the formal printed invitation cards. In the case of a church wedding, the vicar of each parish in which the bride and bridegroom live is normally informed about a month in advance of the ceremony so that an announcement of the coming wedding can be made in church on each of three Sundays before it takes place.Anyone who may know of an existing marriage of either partner is ordered to give information, though this means of avoiding bigamy must have been more effective in the days when people attend the religious service and the bride usually wears the traditional long white dress and veil, while her bridesmaids, who are children, wear long dresses in attractive colors.This may also happen in the case of a civil wedding in a register office but is probably less usual. The reception which follows may be held in a restaurant, a local hall or, when there are few guests, in the bride's own home.Refreshments are provided, a special iced wedding-cake is cut(usually to the accompaniment of speeches)and distributed to the guests, toasts are drunk and dancing may follow.At some point in the celebrations, the bride goes off to change into everyday clothes and then leaves the party with her husband to go on their honeymoon, the journey they will make together, often in romantic surrounding abroad.
