[D]A Disappointing Travel Experience
C篇
In a recent study of healthy volunteers，National Institutes of Health researchers discovered that our brains may replay memories of learning new skills when we rest．
NIH researchers have mapped out the brain activity that flows when we learn a new skill，such as playing a new song on the piano，and found that during short rest the volunteers' brains rapidly and repeatedly replayed faster versions of the activity seen while they practiced typing a code．The more a volunteer replayed the activity，the better they performed during subsequent practice sessions．
The study was conducted at the NIH Clinical Center．The team of Dr．Cohen，M．D．，senior investigator at the NIH's National Institute of Neurological Disorders and Stroke (NINDS)，used a highly sensitive scanning technique to record the brain waves of 33 healthy，right handed volunteers as they learned to type a five digit test code with their left hands．The subjects sat in a chair and under the scanner's long，cone shaped cap．An experiment began when a subject was shown the code “41234” on a screen and asked to type it out as many times as possible for 10 seconds and then take a 10 second break．Subjects were asked to repeat this cycle of alternating (交替的) practice and rest sessions a total of 35 times．
During the first few trials，the speed at which subjects correctly typed the code improved dramatically and then leveled off around the 11th cycle．In a previous study，Dr．Cohen's team showed that most of these gains happened during short rests，and not when the subjects were typing．Moreover，the gains were greater than those made after a night's sleep and were related with a decrease in the size of brain waves，called beta rhythms．In this new report，the researchers searched for something different in the subjects' brain waves．
“We wanted to explore the mechanisms (机制) behind memory strengthening seen during wakeful rest．Several forms of memory appear to rely on the replaying of neural (神经的) activity，so we decided to test this idea out for procedural skill learning，” said Ethan R．Buch，Ph．D．，a staff scientist on Dr．Cohen's team and leader of the study．To do this，Dr．Buch developed a computer program which allowed the team to understand the brain wave activity associated with typing each number in the test code．

故选：C。
（3）设绳1与竖直方向夹角为θ，根据图1的受力分析，橡皮筋与绳1垂直时由平衡条件得：
F＝T2sinθ，其中T2为绳2的拉力，其大小等于水杯与被测物体的总重力。要使装置测量质量范围增大，即使T2较大时F较小，可减小θ的值，故可以采取减小绳1与竖直方向的夹角的措施来增大测量质量范围。
【分析】（1）根据图（b）的x﹣m关系图线读出该芒果的质量；当绳1与橡皮筋不垂直时，作出受力分析图，根据平衡条件判断橡皮筋的拉力F的变化情况，可知橡皮筋长度的变化情况，由图像确定测量的误差。
（2）得到的x﹣m图像在后半部分弯曲与水杯质量过小和绳套长度过大均无关。可能是由于橡皮筋伸长量过大，超出了它的弹性限度所致。
（3）由平衡条件得到橡皮筋的拉力与水杯和被测物体的总重力的关系，据此关系式找到增大测量质量范围的方法。
