网友回答
(答案→)pared
解析：
【小题1】pared。根据中文提示，和后面的介词with可知填pared。
【小题2】who。考查定语从句的引导词。先行词为all those，指的是那些参加考试的学生，故用who引导定语从句。
【小题3】predicted。预测：predict。根据前文considered可知用过去时态，故填predicted。
【小题4】likely。有可能的：likely。这是为了保证原因不只是聪明的学生更有可能携带饮料。故填likely.
【小题5】It。饮料为什么能提高学生的考试成绩仍然不明确。句子结构为it做形式主语，why引导主语从句。故填It。
【小题6】bodies。但是科学家说人体内含有充足的水分并且不会感到渴会对我们的大脑有帮助作用。根据后文not feeling thirsty 可知前面应该填body而不是bottle之类的单词。故填bodies。
【小题7】on/upon。have an effect on/upon: 对.....有作用。句意为对大脑有帮助作用。故填on/upon。
【小题8】down。喝水也许会减少紧张感。cut down：减少。故填down。
【小题9】when。所以下一次，当你要去参加大型考试的时候，尽量随身携带一瓶水。“参加大型考试”为时间状语，所以用when来引导。
【小题10】pass。谁知道呢，它也许会帮助你通过考试的。通过考试：pass the exam。故填pass。
