Section C
The term biological clock is (36) ______ to the means by which living things (37) ______ their activity patterns, without any (38) ______ cue, to the time of day, or the month, or the year. The biological clocks seem to be beautifully (39) ______ to the needs of living things. They are (40) ______ but little, if at all, by drugs, chemicals, or wide temperature difference-factors which may alter substantially the rates of all ordinary (41) ______ of the body.
The nature of the biological clocks' mechanism is still a (42) ______ . Two quite different theories can (43) ______ for them. According to the first of these theories, (44) ___________________________________ . This is believed to have evolved, aided by natural selection, as an adaptation to the rhythmic environment. It has now become independent of the environment. (45) ________________________________________________ . The setting of their biological clocks, therefore, involves a constant adjustment to subtle environment forces. But the search for the specific timing system has been futile thus far. (46) ____________________________________________________ .

答案解析

答案解析：
36. applied
解析：be applied to意思是“被应用到……”。注意将y变成i再加-ed。
37. adjust
解析：注意不要漏了d，尽管该字母不发音。
38. obvious
解析：又一个含有i发出的/I/音的多音节单词，一定要过关哦。
39. adapted
解析：不要漏掉-ed，be adapted to为固定搭配，意思是“对……适合”。
40. affected
解析：被动语态，affect要加-ed；不要把affect（v.影响）和effect（n.影响）混淆。
41. processes
解析：不要少写一个s，或忽略复数词尾es。
42. mystery
解析：中间含有y发/I/音的多音节单词常考。注意拼写，特别是第2个字母。
43. account
解析：account for是固定搭配，意思是“解释，说明”。不要少写一个c。
44. 标准答案：each individual contains its own independent timing system
听音关键：individual, contains, its own independent timing system
答案重构：1) Each individual has a unique timing system
2) All living things have their own independent timing system
3) The timing systems of all living things differ from one another
画龙点睛：这里的individual是指living things中的“个体”，如果拼写没有把握，可以借鉴前文出现的living things。如果改写为people或者human则会有意义上的偏差。
45. 标准答案：The other theory holds that living things react continuously to their rhythmic physical environment
听音关键：The other theory, living things, react continuously, rhythmic physical environment
答案重构：1) The other theory holds that each individual responds constantly to the rhythmic physical environment
2) According to the second/other theory, living things reacts continually to their environment, which is rhythmic
画龙点睛：共提到两个理论，前面介绍了第1个，此空应该是另外一个。"the other theory holds"可以按照前文"according to the first of these theories"改写为according to the other/second theory。这样，整个句子的结构就改变了，原来的宾语从句就上升为一个主句。continually可以用后文中的constantly替换。rhythmic在前文出现过，应该写得出来。 physical environment自然环境，实在写不出physical，宁可不写。
46. 标准答案：Not only has no independent timing system ever been discovered, but there has not yet been even a guess as to its nature
听音关键：no independent timing system, discovered, guess, its nature
答案重构：1) Scientists have neither found any independent timing system nor guessed at its nature
2) No independent timing system has been found yet; furthemore, nobody has even tried to think about its nature
画龙点睛：原句是not only...but (also)结构，可以根据其含义改为并列句。因为原句的两部分都是否定结构，可以用neither...nor...形式引导。尽管independent timing system可能比较难，但是上下文中并不缺少该词组，所以应该可以写出来。此外，也可以根据句子结构的需要把discover与find替换，把guess改为try to think about。
