People who have lost the ability to understand or use words due to brain damage are called aphasics（失语症患者）.Such patients can be extremely good at something else.From the changing expressions on speakers' faces and the tones of their voices,they can tell lies from truths.

    Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.

    Recently,scientists carried out tests to see if all that was said about aphasics was true.They studied a mixed group of people.Some were normal;others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches—in most cases,the normal people were fooled by words,but the aphasics were not.

    Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.

    But his way of speaking had the opposite effect on the patients.They didn't seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!

    Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.

    When I was going home to India last year, I called up my mother to ask if she wanted anything from China.

    When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and jeans. Thankfully, we can get all these anywhere in India now.

    Still, her answer surprised me, “Green tea.”

    As long as I can remember she didn't even drink Indian tea.

    I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses.

    At the turn of the century，China was not really familiar to the average Indians. It was a strange country.

    How things change! And how soon!

    Now every town of any size seems to have a “China Market”. And everyone is talking about China.

    The government of India has planned to send a team to China to see how things are done. A minister once said that India must open the doors for more foreign investments(投资) and such a step would “work wonders as it did for China”．

    But it's a two way street. I just heard about a thousand Shenzhen office workers who have gone to Bangalore to train in software. Meanwhile, all the Indian IT majors are setting up a strong presence in China.

    No wonder that trade, which was only in the millions just ten years ago，was expected to hit about $15 billion for last year and $20 billion by 2008, a goal set by both governments.

    No wonder，my colleague wrote some weeks ago about this being the Sino－Indian(中印) century as the two countries started on January 1 the Sino－Indian Friendship Year.

    But what is still a wonder to me is my mother drinking Chinese tea.

    One of the most important ways to learn and master the English language is to read, read, and read. It is said that a good reader is also a good writer and a good speaker. However, in today's world, reading is something that most children dislike doing.

    There are simply so many distractions (分心的事物) that books, magazines, and newspapers are often ignored and they are in favor of video games and movies. And while video games and movies also play a role in helping the child learn the English language, they still can't quite compare to reading.

    And as a result, kids are learning less and less. Take a look at an elementary level text book. You'll notice that the books for elementary students are filled with pictures and colors. Those pictures and colors in the elementary level text books aren't there just for the sake (缘由) of design. Colors and pictures make us more engaged in the act of learning grammar. They catch our attention and help us retain (保留) more of what we read. This is especially true for little children who enjoy fun English.

    Children are quite easily distracted. When you ask them to sit down and read quietly, their minds will often wander and it won't take long before you find them doodling (涂鸦) and not doing what you told them to do. But if a book is colourful enough to catch a kid's attention, then you'll have a better chance at getting the kid to sit down long enough to learn English.

    The same principle holds true for interactivity (互动). Like colors and pictures, interactive reading materials like English songs for kids also get the child engaged in what he or she is learning. Interactive reading materials get the child to focus since using them is almost like playing.

    If you're a design enthusiast, you're sure to feel dizzy over these jaw-dropping pools.

    Sky Park Infinity Pool, Marina Bay Sands, Singapore

    Located on the Sky Park above Singapore's most famous hotel, Marina Bay Sands this is the world's largest rooftop pool. Offering amazing views of the city's skyline, the pool is at least three times the length of an Olympic swimming pool. As visitors swim toward the edge, they face an illusion that they'll float into the sky-line. It's quite a heart-beaten rush!

    The Red Pool, The Library Koh Samui. Thailand

    This blood-red pool is perhaps one of the most special hotel pools on the list. Set against the backdrop of Koh Samui's Chaweng Beach, the fascinating colour isn't the result of using artificial dye. Rather, the mosaic tiles(马赛克瓷砖) of orange, yellow and red make the brilliant sight that is set among trees and an open-air library.
