[原创] 失利加 一篇阅读JJ 1月8日

ben168

不好意思记性不好。二战失利才发现自己不是牛人（把OG啃5篇就上700分的那种），于是开始做GWD。发现TN　GWD　1中一篇讲TIDE－ASSOCIATED　BEHAVIOR的文章很眼熟，想起来在考试中考过。好像几个题目也一模一样。请老牛加一下。　

另外还考了俄国女人杂志。

其它的就记不住了。说实话，我阅读从来都没读懂过，只知定位和做题。GMAT还真是给我一把教训。

谢谢lz提供信息，是这个吗？

1.        GWD-1-Q25 to Q28生理因素和环境因素对硅藻生物钟产生的影响

      Recently biologists have been

       interested in a tide-associated

       periodic behavior displayed by

Line       the diatom Hantzschia virgata, a

  (5)      microscopic golden-brown alga that

inhabits that portion of a shoreline

washed by tides (the intertidal zone).

Diatoms of this species, sometimes

called “commuter” diatoms, remain

 (10)      burrowed in the sand during high

tide, and emerge on the sand sur-

face during the daytime low tide.

Just before the sand is inundated by

the rising tide, the diatoms burrow

 (15)      again.  Some scientists hypothesize

that commuter diatoms know that it

is low tide because they sense an

environmental change, such as an

alteration in temperature or a change

 (20)      in pressure caused by tidal move-

       ment.  However, when diatoms are

       observed under constant conditions

in a laboratory, they still display

periodic behavior, continuing to bur-

 (25)      row on schedule for several weeks.

This indicates that commuter diatoms,

rather than relying on environmental

cues to keep time, possess an inter-

nal pacemaker or biological clock

 (30)      that enables them to anticipate peri-

odic changes in the environment.

A commuter diatom has an unusu-

       ally accurate biological clock, a

consequence of the unrelenting

 (35)
               environmental pressures to which

it is subjected; any diatoms that do

not burrow before the tide arrives

are washed away.提出现象及其研究

      This is not to suggest that the

 (40)     period of this biological clock is

immutably fixed.  Biologists have

concluded that even though a

diatom does not rely on the envi-

ronment to keep time, environmental

 (45)      factors—including changes in the

tide’s hydrostatic pressure, salin-

ity, mechanical agitation, and

temperature—can alter the period

of its biological clock according to

 (50)      changes in the tidal cycle.  In short,

the relation between an organism’s

biological clock and its environment

is similar to that between a wristwatch

and its owner:  the owner cannot

 (55)      make the watch run faster or slower,

but can reset the hands.  However,

this relation is complicated in intertidal

dwellers such as commuter diatoms

by the fact that these organisms are

 (60)      exposed to the solar-day cycle as

well as to the tidal cycle, and some-

times display both solar-day and

tidal periods in a single behavior.

Commuter diatoms, for example,

 (65)      emerge only during those low tides

that occur during the day.环境因素对其生物钟的影响

1P:  recently biologist interested in T behavior of HV. Some hypothesis… however… indicate, rather than, possess..

2P: not suggest fix. Biologist conclude environmental factors can alter

--------------------------------------------------------------------------------

GWD-1-Q25:

The passage suggests which of the following about the accuracy of the commuter diatom’s biological clock?

             

1. The accuracy of the commuter diatom’s biological clock varies according to changes in the tidal cycle.反

2. The unusual accuracy that characterizes the commuter diatom’s biological clock is rare among intertidal species.

3. The commuter diatom’s biological clock is likely to be more accurate than the biological clock of a species that is subject to less intense environmental pressures.定位32-36

4. The commuter diatom’s biological clock tends to be more accurate than the biological clocks of most other species because of the consistency of the tidal cycle.

5. The accuracy of the commuter diatom’s biological clock tends to fluctuate when the diatom is observed under variable laboratory conditions.

 

--------------------------------------------------------------------------------

GWD-1-Q26:

The author of the passage compares the relationship between an organism’s biological clock and its environment to the relation between a wristwatch and its owner most probably in order to

 

1. point out a fundamental difference between the function of biological clocks in organisms and the use of mechanical clocks by humans

2. illustrate the way in which the period of an organism’s biological clock can be altered by environmental factors

3. suggest that there are important similarities between the biological clock in organisms such as the commuter diatom and the biological clock in humans

4. support an argument regarding the methods used by certain organisms to counteract the influence of the environment on their biological clocks

5. question the accuracy of the biological clock in organisms such as the commuter diatom

---------------------------------------------------------------------------------

GWD-1-Q27:

According to the passage, the periodic behavior displayed by commuter diatoms under constant laboratory conditions is characterized by which of the following?

             

1. Greater unpredictability than the corresponding behavior under natural conditions

2. A consistent periodic schedule in the short term定位第一段 39-41

3. No difference over the long term from the corresponding behavior under natural conditions

4. Initial variability caused by the constant conditions of the laboratory

5. Greater sensitivity to environmental factors than is the case under natural conditions

--------------------------------------------------------------------------------

GWD-1-Q28:

The primary purpose of the passage is to

             

1. dispute the influence of environmental factors on the tide-associated behavioral rhythms displayed by the diatom Hantzschia virgata

2. describe how certain tide-associated behavioral rhythms displayed by the diatom Hantzschia virgata have changed over time

3. compare tide-associated behavioral rhythms to solar-day behavioral rhythms in the diatom Hantzschia virgata

4. examine how certain biological and environmental influences affect the tide-associated behavioral rhythms displayed by the diatom Hantzschia virgata

5. identify certain environmental factors that limit the effectiveness of the biological clock in the diatom Hantzschia virgata

注意文章的进展，前面说了HV所表现的现象，后面说环境因素对其生物钟的影响

GWD18-Q23

Which of the following can be inferred from the passage about the effect of the solar-day cycle on the tide-associated periodic behavior displayed by commuter diatoms?

             

1. The solar-day cycle makes this behavior less advantageous to the commuter diatoms at certain times of the year.
2. The solar-day cycle makes this behavior somewhat more erratic.
3. The solar-day cycle makes this behavior less important to the survival of the commuter diatoms.
4. Because of the solar-day cycle, this behavior is forced to proceed at a more rapid pace at certain times during the 24-hour day.
5. Because of the solar-day cycle, this behavior is not expressed at certain times during the 24-hour day.

就这篇。

另外，有一个数学题，很像上月机经中讨论过的FOG　LIGHT，X%　那种很绕，我想2分钟，最近放弃了。看有哪位同志记得清，再补述一下。

饔牛

GMAC居然这么无耻，这道题目居然还用

版本一： In the store of a car dealer, less than 10 cars are equiped with fog light, and 40% of the cars have  **window, Is the dealer has more car with fog light than those with **window?

(1) 80%的车有雾灯但是没有windows T

(2)52 cars have fog light or window or both

选A，因为不是问具体数据

版本二：

遇到了讨论很激烈的那道window和fog light的题，题目是说“不少于10辆车有fog light,40％有window的有fog light。好像是问多少辆车有window?

(1)20％的fog light有window

(2)52辆车有fog light或者window或者都有

这个选C因为问具体数值

lz是这个吗？

不是这道原题，但是很相似。　是DATA　SUFFICIENCY，给了两个%，然后a)和b)各给了一个%。

我的记性超烂，真记不住。看哪位能补充一下。

作文很简单：一篇是：GEORGE在某个大学附近开了餐馆，因为生意好，决定在其它三个TOWN开BRANCH，并准备提拔三个雇员（他们一直在这个餐馆）。期望利润会翻三倍。

AI是　公众人物(public figure)应该避免对他们没有经历过的事情发表意见。

还是作文好，到底是自己写的，记得清楚。
