W:Ben,have you chosen an elective course yet for this term?
M:No.Why?
W:You've got to take rock climbing.Rock climbing is a good chance to challenge your body and your will.
We just have the first class and it looks like it's going to be great.
M:You think I should take rock climbing.You've got to be kidding.Besides how can they teach rock climbing when it's completely flat around here.
W:That's not important.You can't just start climbing without any training.You have to get in shape,learn how to use the ropes,the belts.There is a lot of preparation.
M:You don't think it's just a little bit dangerous,
W:Not if you know how to use the safety equipment which is,by the way,pretty high tech,
you have to learn how to use it before you do any real climbing.
M:Well What's the appeal?We'll spend the whole semester studying something we don't actually get to do.
W:We will take a climbing trip during the vacation,but that's not the..Climbing is not the only goal in preparing to climb.You learn patience,mental discipline,and you gain physical strength,especially in your hands.For the first few weeks,we are going to concentrate entirely on hand and upper body exercises.
M:All that in one sport,maybe you are right since it's not too late to join the class,maybe I will.
