composition, and technique might view the same work as an attempt to combine color foi
visual impact, or as an experiment with certain brush-stroke techniques.
To sum up, I concede that as students and scholars our working "materials"--facts, data,
objects, and events--are open to subjective interpretation in terms of what they teach us.
However, what our materials teach us is a function of what we've already learned, and has little
if anything to do with our personal basket of emotions and moods called "personality."

"As we acquire more knowledge, things do not become more comprehensible, but more
complex and more mysterious."
Does knowledge render things more comprehensible, or more complex and mysterious? In
my view the acquisition of knowledge brings about all three at the same time. This paradoxical
result is aptly explained and illustrated by a number of advances in our scientific knowledge.
Consider, for example, the sonar system on which blind bats rely to navigate and especially
to seek prey. Researchers have learned that this system is startlingly sophisticated. By
emitting audible sounds, then processing the returning echoes, a bat can determine in a
nanosecond not only how far away its moving prey is but also the prey's speed, direction, size
and even specie! This knowledge acquired helps explain, of course, how bats navigate and
survive. Yet at the same time this knowledge points out the incredible complexity of the
auditory and brain functions of certain animals, even of mere humans, and creates a certain
mystery and wonder about how such systems ever evolved organically. 感谢您阅读《GRE作文范文大全（68） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。GRE作文是中国学生比较头痛的，经常准备很多时间最后还是只得到3.5。我之所以得到6分，个人认为我的文风比较淳朴扎实，有科学性，写的思路比较广(正、反、特)，字数也比较多(I800+、A700+)。
Or consider our knowledge of the universe. Advances in telescope and space-exploration
technology seem to corroborate the theory of a continually expanding universe that began at
the very beginning of time with a "big bang." On one level this knowledge, assuming it qualifies
as such, helps us comprehend our place in the universe and our ultimate destiny. Yet on the
other hand it adds yet another chapter to the mystery about what existed before time and the
universe.
Or consider the area of atomic physics. The naked human eye perceives very little, of
course, of the complexity of matter. To our distant ancestors the physical world appeared
simple--seemingly comprehensible by means of sight and touch. Then by way of scientific
knowledge we learned that all matter is comprised of atoms, which are further comprised of
protons, neutrons, and electrons. Then we discovered an even more basic unit of matter called
the quark. And now a new so-called "string" theory posits the existence of an even more
fundamental, and universal, unit of matter. On the one hand, these discoveries have rendered
things more comprehensible, by explaining and reconciling empirical observations of how
matter behaves. The string theory also reconciles the discrepancy between the quantum and
wave theories of physics. On the other hand, each discovery has in turn revealed that matter is
more complex than previously thought. In fact, the string theory, which is theoretically sound,
calls for seven more dimensions---in addition to the three we already know about! I'm
hard-pressed to imagine anything more complex or mysterious.
In sum, the statement overlooks a paradox about knowledge acquired, at least when it
comes to understanding the physical world. When through knowledge a thing becomes more
comprehensible and explainable we realize at the same time that it is more complex and 感谢您阅读《GRE作文范文大全（68） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。GRE作文是中国学生比较头痛的，经常准备很多时间最后还是只得到3.5。我之所以得到6分，个人认为我的文风比较淳朴扎实，有科学性，写的思路比较广(正、反、特)，字数也比较多(I800+、A700+)。

"It is a grave mistake to theorize before one has data."
Is it a "grave mistake" to theorize without data, as the speaker contends? I agree insofar as
to theorize before collecting sufficient data is to risk tainting the process of collecting and
interpreting further data. However, in a sense the speaker begs the question, by overlooking
the fact that every theory requires some data to begin with. Moreover, the claim unfairly
ignores equally grave consequences of waiting to theorize until we obtain too much data.
In one important respect I agree with the speaker's contention. A theory conjured up without
the benefit of data amounts to little more that the theorist's hopes and desires-- what he or she
wants to be true and not be true. Accordingly, this theorist will tend to seek out evidence that
supports the theory, and overlook or avoid evidence that refutes it. One telling historical
example involves theories about the center of the Universe. Understandably, we ego-driven
humans would prefer that the universe revolve around us. Early theories presumed so for this
reason, and subsequent observations that ran contrary to this ego-driven theory were ignored,
while the observers were scorned and even vilified.
By theorizing before collecting data the theorist also runs that risk of interpreting that data in
a manner which makes it appear to lend more credence to the theory than it actually does.
Consider the theory that the Earth is flat. Any person with a clear view of the horizon must
agree in all honesty that the evidence does not support the theory. Yet prior to Newtonian
physics the notion of a spherical Earth was so unsettling to people that they interpreted the
arc-shaped horizon as evidence of a convex, yet nevertheless "flattish," Earth. 感谢您阅读《GRE作文范文大全（68） 》一文，查字典出国留学网()编辑部希望本文能帮助到您。
