The tallest building in the United States, the One World Trade Center, opened on November 3, 2014 in New York. The building is 1,776 feet tall, making it the 3rd tallest building in the world. It has 104 floors. The building stands in the area where the twin towers of the World Trade Center once stood. On September 11, 2001, a group of terrorists destroyed these twin towers and killed nearly 3,000 people. It took 8 years to build the new One World Trade Center. Does the height of the building in feet reminds you of something in history? The number is the year when the United States declared(宣布) its independence(独立) from Great Britain.

    One problem with such a tall building is how to clean the windows. Well, a platform(平台) hangs from ropes, and workers on the platform clean windows. On November 12, while two men were busy cleaning windows, a rope of the platform broke near the 68th floor. The two men were saved by cutting a hole in the glass window.

The two tallest buildings in the world are the BurjKhalifa in Dubai, UAE and the Makkah Royal Clock Tower in Mecca, Saudi Arabia.

    Next time you make yourself a hot cup of tea or coffee, you might want to let it cool down a bit before drinking.

    Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer. Researchers at the International Agency for Research on Cancer (IARC) found evidence that drinks at temperatures above 65℃, when swallowed, can cause cancer of the esophagus (食道). The researchers examined findings from other studies where tea and coffee were often served at 70℃ or above. Those studies were completed in Iran, China and South America.

    In developed countries, health experts have linked esophageal cancer to smoking and alcoholic（酒精）drinks. However, this form of cancer is more common in areas where people drink beverages（饮料；酒水）at very high temperatures.

    In Europe and the United States, many people drink coffee and tea at temperatures around 60℃.And they often add milk which lowers the temperature greatly. However, tea-drinkers in Iran and mate-drinkers in South America often enjoy their beverages at closer to 70℃.

    The researchers find that South Americans not only drink their mate very hot, they also drink it through a metal straw(吸管). This sends the scalding liquid directly into the throat.

    The findings, however, are good news for coffee drinkers. In 1991, the World Health Organization listed coffee as possibly carcinogenic (致癌的).” The WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink itself.

    The results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.

    Robots come in many shapes and sizes. But most have one thing in common. They are built to help people. Lately engineers have been developing new kinds of humanoid robots. These high-tech machines are designed to lend a hand everywhere from hotels to disaster areas.

    "Robots help people by making their lives easier, safer, and more fun," says engineer Omar Abdelwahed.

    Since November, a robot named pepper has been on the job at the Mandarin Oriental hotel in Las Vegas, Nevada. When guests have questions or need directions, they can ask Pepper. They can also use the robot's touch screen to find the information they need. Pepper is able to talk with guests and entertain them with stories too. It can even tell what kind of mood they are in.

    "Pepper provides our guests with information in an exciting and new way," says hotel manager Donald Bowman.

    For a kid, being in the hospital can be boring and even scary. But a small robot called NAO is helping to make hospital stays easier. It was designed to keep people company.

    A Tennessee doctor named Phil Parker bought a NAO robot three years ago. He programmed it to talk to and play with young patients. He brings it to hospitals to help sick kids. When kids get medical tests, NAO explains what is going on. The robots also reads to kids and plays games with them like rock, paper, scissors.

    "The robot gets many kids to smile for the first time since they've been in the hospital," Parker says.

    Other robots are being developed to help in places where it's hard or risky for people to go. For example, disaster areas can be full of rubble and other dangers. Engineers in Japan are building a robot called E2-DR to go into those areas and search for people who are hurt.

    It's probably my favourite bookstore ever. It's "designed for travelers who like reading". It is famous for its travel book collection. Categorized by country and region, you can find books on history, arts, food, culture, film, literature, and many more topics of the region. It's absolutely fascinating. My favourite is the London literature section near the entrance. It's very tasteful selection and it's a pleasure just to read a few paragraphs while you browse (浏览). The interior is beautiful. Classic wooden counters, wooden floors, shelves and tables of book are organized nicely. Every time I passed by I had to make a stop there. Staff there are helpful and friendly.

    I love the convenience of Amazon but bookstores with special atmosphere like this just cannot be replaced.

    I don't read books as often as I would like. I just don't have time, and let's be honest, after doing all my schoolwork. I'd rather just put my brain on coast and read an OK magazine and catch up with some news about film stars. I was brought into Daunt while wandering down the street and it's really just an inspiring place and it actually made me want to "read" something. Really, if you're anywhere near the shop, do pop in and just look around, even if you have a love/ hate relationship with reading like I do. The inside of the shop made me look around as if I remember enjoying as a kid seeing some new big store, when in fact it's not new, but the sight of a bookstore with classic design charm is refreshing after spending so much time in libraries.

    Go and see it for yourself. You won't be disappointed!

    A man went into a restaurant and sat down at a table. He ordered the most expensive dishes. The waiter served the meal. He ate it with great joy. Then a small boy came in and sat at his table.

    The waiter came up and said to the man, "What would your little boy like, sir?"

    "Oh, just an ice cream," the man told him. Then he stood up and said to the waiter, "I'm just going out to buy a newspaper."

    He left the restaurant. The waiter gave the boy an ice cream. The boy took it and then stood up and walked to the door. The waiter ran towards him.

    "Excuse me," he said, "But your father hasn't come back and he hasn't paid for his meal or for your ice cream."

    "He's not my father," the boy said. "I don't know him at all."

    The waiter was puzzled. "What do you mean?" he asked.

    "The man came up to me in the street," the boy said, "He asked me if I liked an ice cream. I told him I did. Then he told me to come into the restaurant at 2 o'clock and sat down at his table. He said he'd give me one."

Dear Students,

    I am delighted to be your guest.

    I would like to tell you about myself. I have been a news reporter for the past fifteen years. I chose this job so I could travel the world, but the job has taught me many unforgettable lessons. The work is sometimes difficult. I have seen famines, wars, earthquakes, poverty and death. But I have also seen courage, hope and happiness.

    In India, I visited a city where there were many homeless children. Some were as young as four years old. They lived in the streets and survived by begging or stealing. But then a wonderful lady called Rosa opened a home for them. Within one year, she was looking after two hundred children. She clothed them, fed them, and taught them. She gave them hope.

    Another time, I was in Turkey after a terrible earthquake, in one place. I found an old lady whose house was in ruins, her son was missing and rescuer workers said there was no chance that he was still alive. But the old lady did not give up hope. For four days, she moved heavy stones one at a time by herself. She did not stop until she found her son. He was alive.

    Here in China, I met a young boy with a serious condition. He had undergone twenty operations and spent nearly his whole life in hospital. I thought he would be sad, but when I met him, his smile was so warm and welcoming.

    In life, we need role models that we can admire and learn from. When my life is difficult, I try to remember the courage and goodness of these three people.
