I remember he (she) started by describing how humans moves.And then (later we) went over (the gaits of different) to give the difference of the two legs (legged) and four legs (legged)animals, (like) cats cammels,(camels) lizards.
s: well, (wait) I think i missed the class when you read (went over) how lizzard moves, at least i don't have any notes sign on it.
m: well we talked (in class) about how modern reptile(s) like lizzards run. I think i even copied the diagram5 p% W$ ` c, W- W( }1 \0 N
pro drew on the board.

w: ok, I understand it.(That makes sense) but i (remember reading) read that (in general) animal (evolves so that their feet are right under their bodies.) feed and () involved their body. but i don't see why.
我很佩服自己的,that makes sense,可以写成I understand it. 其实我倒是听到这句话的,但是到写得时候突然脑子短路了,产生自己是听得I understand it.的幻觉
m: that's because even though () (the sprawling gaits) suits lizzards pretty well, there (is a )are major disadvantage to (this arrangement) arrange it. reptile can't run and breathe at the same time. they start breathe short breath between any twelve sides, because when then move from side to side, (they stop briefly between short breaths of anywhere from 2 to 12 strides because) the muscle of left and right legs (sides contract) can att at different times. To breathe though, these muscles (have to) contract (at) the same time, mammuals (mammals don't) have this problem because they can't move from side to side. their feet from (are in the) different position.
