British previous colonial policies led to the spread of English across the world. This wide use of English has been reinforced by the sweeping influence of the U.S. However, the dominance of English as an international language is considered both a blessing and a curse. For one thing, it has accelerated the extinction of some languages. People have been wondering about the possibility of creating a global language which might hold promises for an end to language-caused troubles and conflicts. Unfortunately, attempts to harmonize world languages have met with little success as a result of the reluctance of native speakers of a particular language to adopt another language as their mother tongue. To discard one’s native language is to have the distinct features of his nation erased.

Never before has flying been so controversial. In the space of two years, the environmental damage done by planes has gone from being something quietly discussed by scientists and committed environmentalists, to a headline-grabbing issue no one can ignore. Even those who fly once or twice a year on holiday can’t help but feel a growing sense of guilt, while those opting for trips by car, train or ferry have a self-righteous spring in their steps.(1) Now, however, the backlash is beginning. The tourism and aviation industries are mobilizing, and pointing out some awkward facts. Did you know that some ferries emit far more carbon dioxide than some planes? That driving can release twice as much carbon as flying? A new report from Balpa, the pilot’s union, even claims that planes can be better than train.(2) While there are the campaigners who plot their camp at Heathrow to protest the air travel, in Kenya plans are being drawn up for a very different camp. Looking out from a cliff over the deserts of Samburuland is a stunning hotel, the O1 Malo Eco-Lodge. Revenue from the small number of visiting tourists has allowed the 5,000 acres around it to be transformed from over-grazed cattle ranch to a conservation site. More impressive still is the O1 Malo eye project. Up to 80 per cent of adults in the area suffer sight loss, so the O1 Malo Trust runs regular surgical camps, bringing doctors from the UK to treat them. In January, the camp gave 102 people back their sight. “It’s very simple—all of our visitors fly here,” said Julia Francombe, the founder. “If they stopped coming, it would kill us.”One thing on which all sides agree is that aviation is booming, so it becomes crucial to develop new and less polluting aircraft. Airbus’s claim that it can save the world with the A380 may be far-fetched, but its (3) “gentle giant” plane is far more efficient and quieter than those of 20 years ago.Some environmentalists, however, scorn these advances, saying such measures are a (4) “delusion.” “The aviation industry is likely to vastly overstate the gains that can be made from technological improvements but sadly a climate friendly plane isn’t on the horizon,” says Emily Armistead of Greenpeace.(5) So the question is: who do you believe?

My kids tell me that I am “so 20th century”, which troubles me. A person likes to feel that he is “with it”, as we used to say in the 20th century. So I have been thinking how I might change myself into a true 21st-century man. Clearly, in my advanced state of age I would be foolish to attempt some wild leap into the contemporary fashion. And anyway, my distinctive taste attracts much favorable comment.But if my clothing is too characteristic to change, perhaps I should do something about my lifestyle. So last week I took myself to the NEC for the Smart Home Show which is “the exhibition dedicated to all the latest trends in smart home technology”. It was a shock. How could I have lived for half a century without a fingerprint-operated front door? (“Never lock yourself out of your home again!”) Or vacuum cleaners that suck dust straight into a dustbin, via a system of pipes in your house walls? (All you have to do is rebuild your entire home.) Or automatic garden sprinklers which are so smart that they turn themselves off when it starts to rain? Of course, you could just look out of the window, observe that it’s raining and turn them off yourself, but that would be so 20th century.Besides, those were just the simpler things. For the true smart home owner, a plasma (等离子) TV fireplace is a must. At first glance it’s just an electric fire with a mantelpiece, but press your remote and a giant TV screen rises from the mantelpiece. “Thieves won’t even know it’s there,” a spokesman claimed. Just as well. At 65,280, it would be a pity to have it broken. But the real revolution has happened in the bathroom. Never again need you feel cut off from world events as you go about your washing. Forget the mirrors that turn into TV screens. They’re old hat. The buzz in bathrooms now is all about heated towel-racks that turn into TVs.Enough! I was convinced: I want a smart home. There’s only one problem: The cost you are looking at £18.000 to £25,000 for an average home. Hmm. I won’t be entering the 21st century just yet, then.1. To be “21st century”, the author decided to（）.2. The author’s comment on the vacuum cleaner implies that（）.3. What is the most revolutionary smart home technology according to the author?4. The Smart Home Show（）.5. What does the author think of buying the smart home products?
