The hit movie Notting Hill(诺丁山)begins with a famous scene. Hugh Grant bumps into Julia Roberts and spills orange juice all over her. After the collision, Grant repeatedly says, “I'm so sorry. I'm so sorry.”
His actions in this scene are very British. If Roberts' character were from the Britain, than she would probably apologize repeatedly as well – even if the crash were not her fault. But this doesn't happen in the movie, as Roberts is from the US.
A report in The Telegraph once said that three quarters of British people apologize when they bump into someone in the street – regardless of whether they are responsible or not. In fact, Britons use “sorry” in many situations. For example, if they mishear someone, they say “Sorry?” The person they are talking to will also apologize by replying, “No, I am sorry!” This can go on for up to five minutes as they compete over who is the most sorry.
Why are Britons so sorry? Mark Tyrell, a psychology writer in the UK, thinks that their apologetic tendencies are rooted in British class system. “We say sorry because historically the new middle class in Britain had to apologize for not being the working class, but also for really being the upper class.” Another theory is that they apologize to avoid conflicts. For example, if they bump into someone, he might get angry. To avoid this, they instantly say “Sorry!”
True manners are about being considerate, and today's constant use of apologizing shows that we are perhaps not as thoughtful as we once were. The word “sorry” has lost some of its meaning.
Do you see my point? Sorry, it might just be a British thing.
Hot Air Balloons
| A hot air balloon is made up of 3 main parts:
The Envelope The actual fabric balloon which holds the air.
The Burner The unit which pushes the heat up into the envelope
The Basket Where the passengers and pilot stand |
The basis of how the balloon works is that warmer air rises in cooler air. This is because hot air is lighter than cool air as it has less mass per unit of volume. Mass can be defined by the measure of how much matter something contains. The actual balloon has to be large as it takes a large amount of heated air to lift it off the ground.
The burner uses propane gas to heat up the air in the envelope to move the balloon off the ground and into the air. The pilot must keep firing the burner at regular intervals throughout the flight to ensure that the balloon continues to the stable. Naturally, the hot air will not escape from the hot at the very bottom of the envelop as firstly, hot air rises and secondly, the floating power keeps it moving up.
To move the balloon upwards, the pilot opens up the propane value which lets the propane flow to the burner which in turn frees the flame up into the envelope. It works in much the same way as a gas grill: the more you open the valve, the bigger the flame to beat the air and the faster the balloon rises.
The “Parachute Valve” at the very top of the balloon is what is used to bring the balloon down towards the ground. It is a circle of fabric cut out of the top of the envelop which is controlled by a rope which runs down through the middle of the envelope to the basket. If the pilot wants to bring the balloon down, he or she simply pulls on the rope which will open the valve, letting hot air escape, decreasing the inner air temperature. This cooling of air causes the balloon to slow its rise.
The pilot can operate horizontally by changing the vertical position of the balloon because the wind blows in different directions at different altitudes. If the pilot wants to move in a particular direction, he or she simply arises and falls to the appropriate level and rides with the wind.
