listen to part of talk in the literature class, the professor is discussing the pritry of agent grace. these two great pone stand out that great examples of the early es pones. they are believed to be nce some time that between 1800 bc and 1700 bc ,partly because the pones refer to e social condition of that time,
condition that be dividen
by the vening who all the give. but just two was the point who lay down corner
of western literature.
well
traditon is drised to a man named homer but we know virturely nothing to this homer. in fact some say that such poet never exist at all ,that need all the ardency that by the single poet, but each poet is coparted several people. this anyway was of us school
litertature . the analysts pointed to
internal evidence such as very vition in the using the pones to argue that each was collect by several regarders. apposing to the analysts were second group scholars called untarian.
后面没听完，没坚持下来，听得很差，感觉有两点原因：1.对文史类单词以及内容的陌生 2.连读依旧听不懂：just who 等连读就变成了 'just two'

WRITE DOWN WHAT YOU HAVE HEARD HERE: listen to part of a
talk in a physics class. ok since we have been talking about machanic and then we still have a
few minutes. let me tell you a little about the agent Greek and what they thought about machnic. they came up with the systems that for them seem to describe and explain different motions of different material. more than 2000 years ago ,
ari sti the acient
a Greek
, assumed that all the matter on the earth were made up of four plain substances: earth water
iront
fire. under this system earth is the densist , water is the next iron
is less and fire is the least
densist of all. the heavy objects were made of earth and water ,and the lighter objects contens the nificont of iron and fire. so when the
observed that different types of matters had different chariteristics. he asumed that this was because different types of matter were compose of
different amonce of the four plam substances. and Aristod also believed that the motion of objects could also be explained by the basic nature of
four prime substances. for example there were with
the basic motion of up and down . Aristato knew this when he released most objects they would drop downward. but he also knew that something were right upward like the somke. Aristado considered that objects downward
upret
motion to be the dominant
nature of the object. so according to Aristato matter like rocks were primly composed of earth. therefore they naturally wanted to move to the central of the earth because they
were all
things their restin place . but fire had ifferent
resting places -the sky. so smoke would natrally rise when it's released because it 's driving into its resting place.
