The term biological clock is applied to the means which living __1__
things adjust their activity patterns, without any obvious cue, the __2__
time of day, or the month, or the year. They are affected but little,
if at all, by drugs, chemicals, or wide temperature differences—
factors may alter substantially the rates of all ordinary processes of __3__
the body.
The nature of the biological clocks mechanism is still a mystery __4__
two quite different theories have been advanced to account to __5__
them. According to the first of these theories, each individual have
envolved, aided by natural selection, an adaptation to the rhythmic __6__
environment. It has now become independent on the environment __7__
according to this view, the clocks are not perfect timers.
They require regular corrections by the natural light and tide cycles
and the changed lengths of the day throughout the year. __8__
The other theory holds up living things react continuously to __9__
their rhythmic physical environment. The setting of their biological
clocks, therefore, involves a constant adjustment to subtle clocks
which are potential perfect times. __10__
答案:
1.^which—by
by the means of 指“通過(guò)……方式”，如果吧means作為先行詞，后面定語(yǔ)從句就要有by，這句話(huà)意思是“生物鐘指的是生物調(diào)節(jié)其行為的方式”。
2.^the time – to
adjust A to B 指A適應(yīng)B，這句指“在沒(méi)有任何提示的情況下，是自己的行為方式適應(yīng)外界的時(shí)間”。
3.factors^--which/ that
這是一個(gè)定語(yǔ)從句，修飾factors，which/that做主語(yǔ)不能省略。
4.clocks—clock’s
5.to（第二個(gè)）--for
account for意思是explain，為固定詞組。
6.^an—as
這句話(huà)意思是“這些是由于對(duì)規(guī)律環(huán)境的適應(yīng)進(jìn)化而來(lái)的”。
7.on—of
be independent of 意思是“獨(dú)立于……，不依賴(lài)……”
8.changed—changing
文章要表達(dá)的是“變化著的長(zhǎng)度”，應(yīng)該用現(xiàn)在分詞。
9. up去掉或者將up改為that
hold本身就有“持……觀點(diǎn)”的意思。
10. potential—potentially
