The idea that people might be chosen or rejected for jobs on the basis of their genes disturbs many. Such【C1】______may however, be a step 【C2】______ , thanks to work just published in Current Biology by Derk-Jan Dijk and his colleagues at the University of Surrey, in England. Dr. Dijk studies the biology of timekeeping—in particular of the part of the internal body-clock that 【C3】______people to sleep and wakes them up. One of the genes involved in 【C4】______ this clock is known as PER3 and【C5】______in two forms. Dr. Dijk’s work【C6】______that one of these forms is more conducive to night-shift work than the other.
The two forms of PER3 【C7】______ into two slightly different proteins, one of which is longer than the other.【C8】______work by this group showed that people with two short versions of the gene are more likely to be "owls", 【C9】______ to get up late and go to bed late. "Larks"—【C10】______, early risers, have two long versions. Pursuing this【C11】______of enquiry, Dr. Dijk and his team have been studying how such people【C12】______to sleep deprivation. Two dozen volunteers, some genetic owls and some genetic larks, were forced to stay awake for two days. The genetic larks reacted to this worse than the owls did.【C13】______, larks given memory tests and puzzles to【C14】______between the hours of four and eight in the morning turned【C15】______far worse performances than did owls.
What【C16】______that may have for employers is not fully clear. Nevertheless, it is intriguing. There may【C17】______come a time when employers【C18】______night shifts will want a blood sample from【C19】______employees—【C20】______to protect themselves against negligence suits should someone have an accident.
【C15】
选项
A、up
B、on
C、in
D、over
答案
C
解析
考查动词短语辨析。根据语境可知,本句意在表达:百灵鸟的表现要比夜猫子差很多。turn in sth.表示“取得,完成,获得”,代入文中,表示百灵鸟完成测试的情况,符合语境。turn up意为“开大,调高(音量等),找到,出现”;turn on意为“打开,接通,突然表现得,依靠”;turn over意为“翻转,认真思考”,均不符合文意。因此正确答案为C.in。
