You might guess that experienced drivers have fewer accidents, but research from insurer AXA has revealed that they are more law-abiding and honest, too. A poll of 2 000 drivers in the UK found that those who have been behind the wheel for eight years or more had not only caused half as many accidents in the last year as less experienced drivers, but were also less likely to have broken the law or lied to their insurer. Experienced drivers were half as likely to have been caught using a mobile phone while driving within the last year; and a third as likely to have been caught driving under the influence of alcohol or drugs, or to have been convicted of dangerous driving. They were also a fifth as likely to have been convicted of driving without a seatbelt. Dishonest behavior appears to be much more common among newer drivers. The UK’s experienced drivers have always been an attractive group for insurers, but the much lower risk they present is rarely fully reflected in their premiums. This is why AXA has entered the direct car insurance market with a product that rewards them with a no-claims discount of up to 90 percent--far higher than anything else on the market. Only those drivers who have been claim-free for eight years or more will be eligible, which could offer large savings for around a third of motorists. AXA’s research has enabled it to tailor not only the pricing to these expert drivers, but the service, too. AXA Car Insurance will offer a courtesy ear whenever yours is out of action due to accident, fire or theft, not just while it’s being repaired. The survey found they wanted higher service levels too, so customers will be able to change their policy details online or track a claim at any hour of the day or night, every day of the year. Many drivers wrongly assumed they were insured if they were injured in accidents that are their faults. To plug the gap, AXA has introduced Driver Injury Cover,which pays up to £1 million for medical treatment and loss of earnings for an additional annual premium of £34.99--less than £3 a month. Cocky newer drivers do appear to be somewhat overconfident. A third of those who’d been on the road for between only one and two years claimed they were already experienced drivers, and that rose to a half among those who’d been driving for just one more year. But, as AXA’s survey demonstrates, they have still got a lot to learn., they will need to be driving for at least five more years before they can take advantage of that 90 per cent no-claims discount. More experienced drivers are likely to ______.
A. abide by law and seldom lie
B. be caught by using cellphone while driving
C. drive without a seatbelt
D. drive after being in liquor
The word "globalization" usually conjures up images of globe-spanning companies and distance-destroying technologies. Its enablers are the laws of comparative advantage and economies of scale. In The Great Brain Race Ben Wildavsky points to another mighty agent o globalization: universities. These were some of the world’s first "global" institutions. In the Middle Ages great universities such as Paris and Bologna attracted "wandering scholars" from across Europe. In the 19th century Germany’s research universities attracted scholars from across the world. In the early 20th century philanthropists such as Cecil Rhodes and William Harkness established scholarships to foster deeper links between countries. By the 1960s globe-trotting professors were so commonplace that they bad become the butt of jokes. (What is the difference between God and professor so and so God is everywhere. Professor so and so is everywhere but here. ) Universities are obsessed by the global marketplace for students and professors. They are trying to attract as many students from abroad as possible (not least because foreign students usually pay full fees). Nearly 3 million students now spend some time studying in foreign countries, a number that has risen steeply in recent years. Universities are also setting up overseas. New York University has opened a branch in Abu Dhabi. Six American universities have created a higher-education supermarket in Qatar. Almost every university worth its name has formed an alliance with a leading Chinese institution. But globalization is going deeper than just the competition for talent: a growing number of countries are trying to create an elite group of "global universities" that are capable of competing with the best American institutions. China and India are focusing resources on a small group. The French and German governments are doing hattie with academic egalitarians in an attempt to create European Ivy Leagues. Behind all this is the idea that world-class universities can make a disproportionate contribution to economic growth. This is a fascinating story. But Mr. Wildavsky, a former education reporter who now works for both the Kauffman Foundation and the Brookings Institution, is too earnest a writer to make the best of it. He wastes too much ink summarising research papers and quoting "experts" uttering banalities. And he fails to point out the humour of sabbatical man jet-setting hither and thither to discuss such staples of modern academic life as poverty and inequality. Mr. Wildavsky should spend less time with his fellow think-tankers (who are mesmerised by the idea of a global knowledge economy) and more talking to students, who experience the disadvantages as well as the advantages of the new cult of globalization at first hand. Which one is NOT the shortcoming of Mr. Wildavsky’s writing
A. He pays more attention to experts’ banalities.
B. He spends less time with his fellow think tankers.
C. He spends too much time in summarizing the papers.
D. He is too earnest to get the best of it.
