Trees are useful things to man in three important (way) they give us wood and other useful things, they give us cool places, they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that third of these points is the most important. Man wants to make money from trees, so he has cut them down large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless (plant) and look after new trees. So the forests (slow) disappear.

This does not only mean that man will have fewer trees. The results are even (bad) : for where there are trees, their roots break up soil allowing the rain to sink in and also bind (固定) the soil, thus preventing it from (wash) away easily; but where there are no trees, the rain (fall) on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing (leave) but useless desert.

    A Toronto man is offering a free round-the-world air ticket to the right woman. But 1 apply. You must be named Elizabeth Gallagher and have a Canadian 2.

    Jordan Axani, 28, said he and his then girlfriend, Elizabeth Gallagher, booked heavily discounted round-the-world air tickets in May, but their 3 ended and he did not want her ticket to 4. The ticket had a strict no-transfer(不可转让)5, but since passport information was not required when 6, any Canadian Elizabeth Gallagher can 7 it.

    "I just want to see the ticket go to good use and for someone to 8 a lot of joy," said Axani. He posted his 9 on a social networking website, and received thousands of e-mails, including thirty from actual Elizabeth Gallaghers with the 10 passports. "More 11, there are hundreds of Canadians who are interested in 12 their name to Elizabeth Gallagher," Axani said. "It was absolutely out of 13, thousands of e-mails, people around the world 14 their stories of travel.”

    Axani wrote in his post that he is not 15 anything in return and that the woman who uses the 16 ticket can choose to either travel with him or 17 the ticket and travel on her own.

    The 18 is scheduled to start on December 21 in New York City and continue on to Milan, Prague, Paris, Bangkok and New Delhi before 19 in Toronto on January 8. He said the 20 woman will be announced on the website and the trip will be shared online.

Have you ever noticed how Americans fill up their entire glass with ice and then pour their beverage (饮品) in, but Europeans take their drinks at room temperature?  In the U. S., we've created fridges that give you cold ice at the press of a button, but in Britain they typically serve their tap water warm.

This tradition—if that's what you want to call it—dates back to the 19th century. During that time, it was already commonplace for most American homes to have an ice box. Ice would be harvested in northern America or Canada and shipped across the Atlantic and sold at a high price in British department stores. Can you imagine heading to Macy's to treat yourself to a block of ice?

Putting ice in your drink started to become somewhat of a fashion trend for the wealthy in Britain. Some would put a few cubes in their champagne and sip on their chilled drinks at high-class parties. But, like with any fashion trend, it eventually faded, mainly because the ice was just too expensive. And even once ice boxes began appearing in homes in Britain as well, Brits never took a liking to ice in their drinks.

So, next time you travel overseas, don't feel offended (被冒犯) when your server gives you an eye roll when you ask for ice water.
