6 p1 `$ l7 o- D3 J1 iM:Now let's see Professor Stone spent a lot of time talking how animals walk <and run>.I remember she started by describing how human's move. <and later we went over the gaits of> different 2-<legged> and 4-<legged> animals.like cats....camels..lizards......
9 |8 e# {6 T6 s  oW:Wait, I think I missed the class when <you went over> how lizards move, At least, I don't have any notes on it.+ V1 E  f: Y3 q8 \, v) X
M:Well, we talked <in class about> how <modern> reptiles <like lizards> run. I think I even copy the diagram the Professor <drew> on the board.Here it is. Now look at this, Lizards run with what's called <as> sprawling gait. ..their feet are <well> out on either side of their body, and they move diagonally opposite feet together. the left <fore> foot with right <hind> foot,and the right <fore>  foot with the left <hind> foot. They use this way of moving when they're going slowly or quickly.when they move, they bent their bodies from side to side. and they <time this bending so that they> increase <the length of> their teps.
4 c# ?7 z: x/ B7 VW:OK,that makes sense. but i remember reading that , in general, <animal evolves so that>their feet are <right> under  their body.But i don't see why.
5 G6 ?: ~! B$ t% s% V$ X" z# UM:That's because <even the sprawling gaits>the feet suits the lizards pretty well, there's a major disadvantage to this arrangement ,<Reptiles can't run>   and breathe at the same time.They stop <briefly between short breaths of anywhere from 2 to 12 strides because >when they move from side to side , the muscles of the left and right sides contract at different times.To breathe though,these muscles have to contract at the same time.Mammals don't have this problem,because they don't move frome side to side. Their feet are on different position.

0 E$ S9 W! N7 e! m* e. WPeople are always talking about 'the problem of youth'. If there is one -- which I take leave to doubt -- then it is older people who create it, not the young themselves. Let us get down to fundamentals and agree that the young are after all human beings -- people just like their elders. There is only one difference between an old man and a young one: the young man has a glorious future before him and the old one has a splendid future behind him: and maybe that is where the rub is.
& v- o- t* V6 F! m* u  ]% h9 W- c    When I was a teenager, I felt that I was just young and uncertain -- that I was a new boy in a huge school, and I would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking.
; W/ p% o5 M4 n  f& @    I find young people exciting. They have an air of freedom, and they not a dreary commitment to mean ambitions or love of comfort. They are not anxious social climbers, and they have no devotion to material things. All this seems to me to link them with life, and the origins of things. It's as if they were, in some sense, cosmic beings in violent and lovely contrast with us suburban creatures. All that is in my mind when I meet a young person. He may be conceited, ill-mannered, presumptuous or fatuous, but I do not turn for protection to dreary cliches about respect of elders -- as if mere age were a reason for respect. I accept that we are equals, and I will argue with him, as an equal, if I think he is wrong.....

Listen to part of the talk being given by a gas lecturer in an astronomy class.It's my pleasure to come you today to talk about Galileo mssion to the planet Jupiter. Glileo was <launched> in 1989 and we have to wait till the end of 1995 for the spacecraft <and its probe> to reach Jupiter. Of course there's some exciting moment for a longer way too. <I> first <visited Dr.Black's> astronomy class--<back to Galileo, had just visited the Asteroid Belt>..I was able< at that time> to bring Galileo's <images of the Asteroid Gasper> . That was first time I got a <up-close> look at the asteroid.It was just amazing.but There are some dispointments.In 4 <of> 1991, we realised that one of the <antennas that was> supposed to transmit data had no functioned. That meant we had to <rely on the smaller antennas>to give us data. But <we have ended up been  quite  pleased with what we see> from Gelileo.As I mentioned before, <at the end of> 1995,<the Galileo probe finally entered> Jupiter's <atmosphere>.We knew <Jupiter's position> at that time <will make communication with the spacecraft >difficult , so we <decided to suspend data>  transmission. After <waiting about half a year,> we continue <collecting it> for 2 years. Now <what you > have to <be> waiting for ,<direct images of > Jupiter.
