I’m Lovin’ It

We all have our fantasy headlines -- the announcement of events of global or national significance that chime irresistibly with our own personal values and ambitions. "Texas oil reserves found to be unlimited" would probably be George Bush’s. Though I suppose it might be trumped by "WMDs found in Iraq -- and Iran".

At last, it seems that McDonald’s is losing its hitherto stellar domination of the vast fast-food market in this country. This is not a regional or temporary blip, or a mere tactical realignment. They really are in trouble. Their poor performance in Britain dragged profit margins from McDonald’s European company-owned restaurants down to 14.9% of sales last year -- from 15.6% in 2004. No new openings are planned for the coming year. Even McDonald’s European boss, Denis Hennequin, is struggling to put a happy face on the situation: "The UK has been in negative territory for a couple of years now

[单项选择]TOKY—Our kids, the Japanese government announced, have forgotten how to behave. They can’t be bothered with housework. If they see someone being wronged, they probably look the other way.
Few countries have placed more importance on being well-behaved in public than Japan. The simplest requests for directions often result in guided tours. Smiling shopkeepers are still the rule. Lost wallets usually make their way to their owners.
But according to recent surveys, all that may be going the way of the ancient hairdo. And Japan’s government has gone into something of a crisis mode.
A Japanese Education Ministry Survey formed late in 1999 and made public last month found that Japan moves behind other nations in teaching youngsters right from wrong.
It also reported that Japanese children are less helpful and do far less housework than their foreign peers in all classes. But they are better about taking dirty dishes to the kitchens after dinner.

[单项选择]What is your favorite color Do you like yellow, orange, red If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tells us, and they should know, because they have been seriously studying the meaning of color preference, as well as the effect that colors have on human beings. They tell us, among other facts, that we don’t choose our favorite color as we grow up--we are born with our preference. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
Colors do influence our moods, there is no doubt about it. A yellow room makes most people feel cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing. A bl
