问题     "Before the operation, I would look at someone and all I could see for their face was jelly," says Jonathan Wyatt "Now, I can see people’s faces." The 66-year-old is one of six people in the world to receive gene therapy for a【C1】______ type of inherited eye disease【C2】______ choroideremia (an eye disease). The first published【C3】______ of the trial, released today, suggest that【C4】______ people’s genes can stop the disease from causing blindness—and【C5】______ sight in those whose vision has become【C6】______.
    Choroideremia is caused by【C7】______ in the CHM gene In those who have the disease, a 【C8】______ of REP-1 means that cells in the eyes stop working and slowly begin to【C9】______ causing blindness. Enter gene therapy, which uses a virus to insert a【C10】______ copy of a gene into cells with a gene defect and could【C11】______ be used to treat many genetic conditions. Robert MacLaren of the University of Oxford and his colleagues decided to see if it could【C12】______ choroideremia. Starting two years ago with Wyatt, they【C13】______ a virus carrying a corrective copy of the CHM gene into the eyes of people with choroideremia Today the team【C14】______ that of the six people who received the treatment six months【C15】______ or longer, all have described【C16】______ in their vision. Still, the long-lasting effects of the treatment remain【C17】______. Wyatt had the treatment first, so can【C18】______ that the benefits seem to last two years, 【C19】______ he’s just one case. The treatment also can’t replace cells that have been【C20】______ destroyed.
【C18】
选项 A、regard
B、advise
C、predict
D、reveal
答案D
解析 本空格应该填入一个动词，这个动词的主语是Wyatt，Wyatt是第一个接受基因治疗的人，时隔两年了，效果依然好。可以判断这里是拿Wyatt作为例子来探讨基因疗法的长期效果。D项reveal“显示”符合此处语义。
