Singapore is building an airport where indoor trees, waterfalls and a 'rain vortex' sit alongside check-in queues, waiting rooms and baggage carousels(传送带).

    Where once sat a car park, there will soon be thousands of trees and plants across 22,000 square metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world's tallest. These are the plans for the new 3.5 hectare 'Jewel' development at Singapore's Changi Airport, scheduled to open in 2018; a five-story, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

    “The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

    Promised sustainability（持续性） measures include “extensive usage of photovoltaic panels（光电板）”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

    The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. 'In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.'

    Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel's design.

    However, it remains to be seen whether, beyond the aesthetic (审美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also  fun,” Several says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    The ancient city of Xi'an in China holds many treasures. And last month, archaeologists working there made an important discovery—a buried palace built in the third century B.C. to honor China's first emperor.

    The entire palace measures roughly 2,260 feet long by 820 feet wide. It includes 10 courtyard houses and one main building. Archaeologists found bricks and pieces of pottery at the site of the palace, as well as the remains of walls and roads.

    The palace is part of the massive burial complex of Emperor Qin Shihuangdi. He conquered seven warring kingdoms and united ancient China in 211 B.C.

    Qin Shihuangdi wanted his legacy, or accomplishments, to be remembered forever. So he hired more than 700,000 workers to build his funeral complex in Xi'an. It represents a miniature version of his vast kingdom.

    The complex also includes the world-famous terra-cotta army, a collection of more than 8,000 life-size clay statues. These sculptures represent soldiers, acrobats, and horses from the Qin Dynasty (221 B.C.-206 B.C.). Scientists have not yet found all these terra-cotta warriors, even though they discovered more of the statues last summer.

    Farmers discovered the complex by accident in 1974. Since then, scientists studying the site have learned a great deal about life in ancient China. But much of the emperor's tomb has yet to be dug up, or unearthed. Many of the artifacts (objects from the past) are so old that scientists cannot preserve them.

    "Archaeologists fully acknowledge that nobody in the world has the technology (to safely dig up Xi'an's treasures) yet," explains Kristin Romey, an expert on Chinese archaeology.

    But as technology improves, archaeologists will keep digging to uncover the rest of the wonders that still lie buried in Xi'an.

    "It's one of the most important archaeological discoveries that's waiting to be made," says Romey, "and we know where it is."

    There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have traveled to the places, you can go and see a colour film about them, or you can read a travel book.

    It seems that there are three kinds of travel books. The first are those that give a person al, subjective(主观的) idea of travels which their writer has got himself. These books can be useful if the writers share their traveling experiences with others. The second kind are those books which give objective(客观的) information of things to be done and seen. If a cultured person has written such a book about the facts of a place, then it is more useful. The third kind are those books which are called “a guide” to some place or other. If they are good, they will describe and explain the place in detail. Like the first kind, they can be interesting and exciting, but their main purpose is to help the reader plan his travel in the most practical way. Whatever kind of travel book you choose, you must make sure that the book does not describe everything as interesting, exciting or fantastic. You must also keep an open eyes on its date of publication(出版) because travel is very practical matter and many things change quickly in the 21st century. Finally, you should make sure that it's easy to find the useful information for you travel.

    Britain's pub landlords (酒吧店主) are looking with a worried eye to the UK Chancellor's budget for fear that the annual tax gathering round will strike another blow to a traditional industry already reeling (蹒跚). Thousands of pubs have closed since the financial crash in 2007.

    The Plough, which was once a coaching house for travelers, has been serving Britain's famous warm beer since the days of Shakespeare. Now it is under threat too. "Yeah. So many pubs have been closed over the last few years even in this area," said Derek O'Neil, the manager of The Plough Pub.

    Many reasons are the cause—a ban on smoking in public, severe laws against drinking and driving and high taxes have all combined to kill off nearly 10,000 pubs in the last seven years, according to the British Beer and Pub Association. With the closures, pubs are being redeveloped. Many have turned into supermarkets, where the beer is sometimes cheaper.

      Britain's pubs continue to play an important part in the UK economy, selling thousands of different beers and employing more than a million people. The reality, though, is pubs are suffering something of a hangover (遗留物). In the last 15 years the amount of beer sold in pubs has fallen by eight million barrels to just under 36 million a year. Pub landlords want tax breaks (税务减免).

    "People have less money in their pockets, so they can't go out and spend it and habits are changing—so much alcohol is nowadays drunk at home," said Brigid Simmonds, Chief Executive of the British Beer and Pub Association. "Yeah, I miss the pubs where there's a lot of character, especially 30 years ago. You know there was great fun in them."

While pubs are still much loved, they're discovering that love isn't enough to survive 21st century economics.
