   【小题2】    However, according to a recent study, IQ can rise—not just by one or two points, but by as many as 21 points!

   【小题3】    One is to train your short-term memory． Previous research has proven that short-term memory is the basis for intelligence, so trying to recognize or retell something that you have seen or heard can help raise your overall brain power．     【小题4】

Answer 1

【小题1】C
【小题2】G
【小题3】A
【小题4】F
【小题5】E

解析试题分析：
【小题1】C 本文是关于学习方面的脑力训练，能让你和那些充满的孩子一样聪明。故C项符合上下文。
【小题2】G 根据本段IQ can rise—not just by one or two points, but by as many as 21 points!智商可能会有21分的变化，说明以前人们认为智商可能是不变的。故G正确。
【小题3】A 根据本段第一句One is to train your short-term memory．说明本文是关于提高大脑灰质的方法，故A符合上下文。
【小题4】F 根据上句要求我们要多尝试记忆你所看到的或者你所听到的，那样会提高你的脑力。那么这一句就应该是鼓励你尽量多做这样的练习，故F符合上下文。
【小题5】E 根据上句，充足的睡眠也会帮助提高我们的注意力，故E项中关于睡眠的说法符合上下文。
