一、Group discussion about risks

Directions：The following numbers indicate the relative risks of different means of transportation in the USA.Work in groups to answer the questions using the words given below.

Buses 4 Passenger trains 8

Airplanes 10 Passenger cars and taxis 106

Q：1)Which means of transportation is much safer，planes or cars?

2)Why do most people fear airplane accidents more than car accidents?

airplane crash fatal survive (in)secure car accident

A：1)I think airplanes are safer.

2)Although fewer people die in air crash than in car accidents，people feel far less safe in the air than on the ground，maybe because airplane crashes are almost always fatal.If you are in an airplane crash，you will die most probably，but you might not be killed in a car accident.Besides we are still more used to cars than planes.

二、Questions related to risks

1.In daily life，what are the three riskiest things you do?

The three riskiest things I do in a normal day are to ride my bicycle in traffic jam，run down stairs and do scientific experiments

In my opinion，they are crossing the road in heavy traffic，drunken driving，and diving.

2.What should we do to deal with risks in ordinary life?

One way to deal with risk in ordinary life is through rational planning.By considering alternatives and balancing the greatest or most likely risks against the greatest or most likely rewards，we can often make better decisions and give greater consideration to long-term outcomes.By always having a contingency plan in case our main plan fails，we can usually avoid catastrophes.But planning takes effort，and we must balance this effort against the pleasure of doing things quickly because they are not very important or not very risky，and plan other things carefully because they are very important or very dangerous.

三、Organization analysis of the text

Part1 Risks are always a matter of probability rather than certainty

Part2 Nothing we do is completely secure.The point is to decide the level of risk and then act.
