13、ou today about Steve Jobs. Jobs was someone who changed the world, because he changed the way people act every single day. Jobs was born in 1955. He grew up in California, in an area that later became known as the Silicon valley. When he was about 14 years old, he became friends with Stephen Wozniak

14、 Wozniak was what people in those days called an electronics whiz kid. He liked to design and build his own electronic equipment.In 1975， Wozniak started designing a personal computer. This at a time when nobody owned personal computers in their homes. Jobs was young. He was only 20. But even then h

15、e had a sharp business brain. Jobs convinced Wozniak that they could build these personal computers in his garage and sell them. a year later, Jobs and wozniak founded the apple computer Company, and started building and selling personal computers. When their apple ii computer went on the market in

16、1977， it became a huge success Suddenly there was a mass market for a computer that people could buy at a store and use sitting in their own homes The apple ll became the worlds first mass produced personal computer, and by the age of 25， Steve Job was a millionaire.Jobs was brilliant in many ways,

Im sure many of you have taken a ride on a roller coaster Person ally, I dont ever want to ride on one again. When i was young, my sister took me on a

27、roller coaster, and I never forgot that frigh te n in g experience.A simple roller coaster consists o f a frame with a track on it .The track is very much like a train track. Th is track goes over a serie s of hills and around curves following a path that ends at the sam e p lace it started, a train

28、 of cars travels around on th is track, very fast. the cars have two sets of w heels. 0 ne set of w heels rolls on top of the track and the other set of w heels rolls below the track the w heels below the track are there to keep the fa stm oving cars fro m co m in g o ff th e track.Roller- coaster c

29、ars, as you prob ably know, d ont have any m otors or es In stead, a ch ain pulls the cars up the first, tallest and steepest, h ill. A nd th isis how the ride begin s then at the top of the hill, the ch ain com es off th e cars, and gra v ity takes over. Gravity pushes the cars dow n the other sid

30、e of th e h ill. T he taller a nd steeper the first h ill is, the fa ste r th e rid e willbe, and the farther the cars willtrave l.As the cars roll downhill, they gain speed. When they reach the botto m of the first h ill, the cars have enough speed a d e nergy to send the m up the next hill. A s th

31、 e cars n ear the top of the second hill, they begin to slow down. but then, th e cars reach the top of th at hill and start down the other sid e, a n d gravity again pushes them tow ard the ground. T his process repeats on each hill.OK, so lets go over th is process a g ain. First, the cars are u l

32、ed b y a ch ain up th e first, h ig h est h ill. Then they go d ow n a very steep slope At th is point, there is enough energy to pull the cars up and over the next hill. a gain, w hen they reach the bottom of that hill, there is enough energy to clim b the next h ill. T he roller-coaster cars lose

33、energy as the rid e contin ues so the hills have to be sm aller toward the end of the track F in ally, we roll to a stop on ground level, rig ht w here we began.Tom orrow we will talk about the forces that press on our bod ies and keep us in our seats w hen the cars of a roller coaster travel in a loop th at puts
