问题     Of the many factors that contribute to poor performance on standardized tests like the SAT, nerves and【C1】______, surprisingly, may not rank very high. In fact, according to a new paper published in Journal of Experimental Psychology, a little anxiety—not to mention fatigue—might actually be a very good thing.
    The study was conducted by psychology professors Phillip Ackerman and Ruth Kanfer. They【C2】______239 college freshmen, each of whom agreed to take three different versions of the SAT reasoning test given on three【C3】______Saturday mornings. The tests would take three-and-a-half hours, four-and-a-half hours and five-and-a-haif-hours, and would be administered in a【C4】______order to each of the students. To【C5】______the stress level in the students—who had already taken the SAT in the past and gotten into college—Ackerman and Kanfer offered a cash【C6】______to any volunteers who beat their high-school score.
    Before the test began on each of the three Saturdays, the students filled out a questionnaire that asked them about their fatigue level,【C7】______and confidence. They completed the questionnaire again at a break in the middle of the test and once more at the end. Together, all of these【C8】______a sort of fever chart of the students’ energy and anxiety throughout the experience.
    When the researchers scored the results, it came as no surprise that volunteers’ fatigue and stress rose【C9】______as the test got longer. What was【C10】______was their corresponding performance: as the length of the test increased, so did the students’ scores. The average score on the three-and-a-half hour test was 1,209 out of 1,600. On the four-and-a-half-hour version it was 1,222; on the five-and-a-half-hour test it was 1,237.
    A)provided B)random C)outrage D)bonus
    E)dramatically F)recruited G)terminated H)eliminate
    I)consecutive J)exhaustion K)deliberate L)unexpected
    M)boost N)steadily O)mood
【C5】
选项
答案M
解析 to提示此处需填入动词原形。破折号中的定语从句表明受试学生以前考过SAT，再结合句末“成绩超过高中分数”(beat their high-school score)，推知研究人员给学生设定更大的压力。boost“增加”符合语义。
