Could a plant virus have found a way to infect humans? It has always been assumed that plant viruses cannot infect animals, and vice versa, but plant viruses are known to be【C1】______in human faeces(粪便).
Now Didier Raoult at the University of the Mediterranean in Marseille, France, and his team think a pepper virus is making people【C2】______, too. They have found RNA from the pepper mild mottle virus in the faeces of 7 percent of the 304 adults they tested. Those with the virus were more【C3】______to report fever, abdominal pain and itching(痒)than those without it, his team found.
Not everyone is convinced, however. Because Raoult looked at many possible【C4】______, he would be expected to find a few that randomly【C5】______more common in virus-positive people, says Robert Garry, a virologist at Tulane University in New Orleans, Louisiana. Moreover, in order to enter a cell and replicate, a virus must bind to a receptor on its surface, and a plant virus would be highly unlikely to【C6】______a receptor on a human cell, says Garry.
One possibility, Raoult says, is that the virus does not infect human cells【C7】______. Instead, the naked viral RNA may alter the【C8】______of the cells through a mechanism similar to RNA interference, in which the presence of certain RNA sequences can【C9】______genes on and off. Raoult’s team is now working to【C10】______more direct evidence that the virus does infect humans.
A)abundant F)function K)situations
B)appear G)gather L)surprisingly
C)available H)likely M)symptoms
D)capacity I)recognise N)tested
E)directly J)sick O)turn [br] 【C3】
选项
答案
H
解析
形容词辨析题。分析句子结构可知,空格所在句主语为Those with the virus,空格在系动词were和比较级标志more之后,因此应填形容词。根据句意可知,那些体内携带这些病毒的人——发烧、腹痛和瘙痒。再结合备选项可知,likely“可能的"符合题意。be likely to do意为“可能做……”。
