GWD 1中的阅读题，XDF兰皮150页给的题目不同

做XDF兰皮上遇到的问题，结果打开对应的GWD，居然没有这道题，真是怪了。上过课的同学直接翻到page150，我要问的事Q1，不知道我在说什么的同学，我已经把原文贴上，题目在后面我打出。

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.

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.

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?

a ) the solar-day cycle makes this behavior less advantageous to the commuter diatoms at certain times of the year

b) the solar-day cycle makes this behavior somewhat more erratic.

c)the solar-day cycle makes this behavior less important to the survival of the commuter diatoms.

d) 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.

e) because of the solar-day cycle, this behavior is not expressed at certain times during the 24-hour day.

答案是c。

我的问题相当初级，我连问题的原文准确定位都找不到。我找到了一些相关词出现的位置，可是都没有直接说明c对的，原文中有说到

可是，as well as的意思可是和less important to 完全不同啊~！

这篇Passage60我觉得答案是错的，查了一些资料之后作的答案是

EBDC

供参考

UP，我也是这个答案EBDC。

XDF和GWD的答案也都互相不一致，真是害人不浅！

有的时候我不由的想，怪不得人家看不起中国制造，这些人做事情认真点会死啊？！
