It is (1) by no means unusual for teenagers to use their video-game consoles to compete over the Internet with opponents from around the world; people they have never met and (1) names they barely know. It was only a matter of time (2) the idea was transferred to other competitive activities. Indeed, the latest online competition has thousands of grown men and women using toys costing (3) to $150,000 to compete via the Internet worldwide. Whats more, it involves those elegant engineless aircraft known (4) gliders.
The key to (5) what is called 'Online Contest' (CLC) is a combination of global positioning system receivers, someone to record the data and the power of the Internet. Glider flying requires the pilot to (6) advantage of thermals, air currents (7) rise up from hot spots on the land. Skillful pilots learn to identify these thermals and by moving from (8) to another, they can travel huge distances. The world record for the longest glider flight stands (9) 3,017 kilometres - which is not bad for an aircraft with (10) engine!
In OLC glider pilots gain one point for every kilometre flown, but the competition is completely flexible, with pilots free to fly from the airfield of (11) choice, to use any glider at any time and fly in any weather conditions. It is (12) flexibility that has allowed the sport to take (13) in such a big way. Last year, competitors logged as (14) as 58,800 flights, performing 17.4 million miles of cross-country gliding (15) the process.

Sometimes the way we view life seems to be determined not by what really happens to us, so much as by our (0) perception (perceive) of what happens. This is sometimes called counterfactual thinking. Let's look at the example of sport. For those who come second in a race, their (1) (close) to winning creates an intense feeling of (2) (satisfy), and they need to find an excuse for their failure. Conversely, bronze (3) (medal) often feel lucky because they nearly didn't win anything at all. It's the same feeling you get when a traffic hold-up leads you to miss a flight. Missing it by an hour is much less (4) (frustrate) than missing it by just a few minutes.
Another type of counterfactual thinking occurs when we regret doing things that cause problems far more than we regret doing nothing, even though (5) (inactive) can lead to just as many problems us (6) (wise) actions.
Counterfactual thinking also happens when we think about the past and wish that something had or had not happened. This desire can be so (7) (powerful) that we can even change our own memories of the past, making (8) (adjust) to the actual facts to create new memories that suit us better. We do this, for example, when we wont to avoid facing up to (9) (comfort) truths.
If we're not careful, therefore, counterfactual thinking can lead us to (10) (write) history, and so lose sight of real events altogether.
