was, were, will be, shall be, prefer, prefers, preferred
During the holiday week, one-third of the students ____ willing to write course papers but ten percent of the teachers ____ in-class examinations.
【正确答案】：were;preferred
【题目解析】：【考点点击】本题考查主谓一致。【要点透析】由“分数、百分数+of+名词”构成的名词词组作主语时,其动词形式取决于of词组中的名词,所以主语是复数,谓语用复数形式。前后两句时态应保持一致,故第一个空填were,第二个空填preferred
