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.
【C20】
选项
A、in case
B、that is
C、if only
D、or else
答案
C
解析
考查逻辑关系。空格前阐述:实行夜班制的雇主会想要一份潜在雇员的血液样本。空格后阐述:如果发生事故,就可以避免因为失职而被起诉。if only可以表示“即使仅仅因为”,代入文中,表示原因,符合逻辑。in case“如果,假使”;that is “也就是说”;or else“要不然”,均不可接后面的“to protect…”。故正确答案为C.if only。
