    It is 2018; e-books are loved by many people. Do you read them?

    An e-book is an electronic book, which can be made from common books and loaded onto an e-reader. The e-reader is a mini-device, just like a cell-phone. It has a touch pad screen and can hold a few hundred e-books. People can read e-books on it just like they do a book. So it is possible for people to read anywhere with an e-reader. This is perfect news for people who love to read books but can't carry many.

    Another great thing is that people can read books on it quickly and there's no need for two hands to hold the book and turn pages. Most e-readers also have a nightlight, so you can read at night and don't wake your partner with a big light on.

    Not all book authors agree to make their books into e-books. The creator of Harry Potter says that her books will never be e-books. However, lots of authors absolutely love the idea and feel it's the next step to keep books alive.

    Nowadays e-books are sold in many websites, from where you can buy and load them onto your e-reader. Those websites look just like ordinary online bookstores and have a list of best sellers and a new book section. There is also a clear price on each e-book to make sure people can buy them like buying common books.

    One of the most exciting and interesting international cities to visit is London, England. Here is a look at four free things to do during a vacation to London.

    Visit the Trafalgar Square

    Built more than 200 years ago, Trafalgar Square is a popular gathering place for locals and travelers, too. The area is close to good shopping and dining opportunities, and there are usually some sorts of public events or celebrations going on there during most weekends.

    Wander Along the Thames

    Visitors wanting to see some great architecture, attractions and views should spend an afternoon walking along the River Thames. The best place to start is at the world-famous London Bridge crossing over the river and you can walk all the way to Westminster Bridge a short distance away. Travelers doing this will find themselves passing by a great many historic buildings.

    Explore the Local Markets

    While purchasing items at any of the open markets in London is not necessarily free, walking through them to view the merchants, their products and the other shoppers is of great fun. Some of the popular open markets in London worth visiting include Spitafields Market, Portobello Road Market and Leadenhall Market.

    Visit the British Museum

    One of the top museums in the entire United Kingdom can be found in London, and it charges no admission for entry. This museum is so highly regarded that it is not only popular with locals and tourists, it is also seen as a major and valuable scholarly resource.

    Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

    The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. Vne pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

    The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot's job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

    Summer holidays are coming. Here are two posters for members of English Club in the  schoolyard：

    The Japanese have always been at the forefront at deploying (利用) robots to perform jobs that are traditionally done by humans. Over the past year, humanoid robots have been seen helping customers at the Mitsubishi Bank and even filling in for human science communicators at museums. Therefore, it is not surprising to hear that the country has the worlds first hotel that is staffed almost entirely by the Androids!

    The aptly (巧妙地) named Henn-na ("strange" in Japanese) Hotel which opened its doors on July 17 is located at Nagasaki's Huis Ten Bosch theme park. It is the idea of Hideo Sawada, a Japanese businessman who is fascinated by the possibility of replacing humans with robots. His aim is to have this futuristic hotel be run mainly by the intelligent humanoids.

    Guests checking-in are welcomed by a family friendly English-speaking robot wearing a bow tie and bell-hop (侍者) hat. Though experienced at his job, he does request guests not to ask him "a difficult question" since he is after all, "just a robot!" Those seeking a more "regular" experience, can approach the human-like Japanese-speaking robot.

    When ready, visitors can request the robot "porters" to help carry belongings to their room. Those that need to stow away valuables can hand them to a helpful robot who will place them inside an individual safe box in exchange for a small fee. A one-foot-high concierge (管理人) is available to provide information about the hotel's amenities (便利设施), nearby attractions, and even order a taxi if needed.

    So how much does it cost to live in this crazy cool hotel? It depends on when you decide to go. During the low season, guests can get away with paying as little $60 a night for a basic room. However, during the peak season when rates, are determined by an online auction, the price can get as high as $153.
