问题 Scientists now have some surprising answers about whether brain power______as we get older.

选项 A、reduces
B、descends
C、declines
D、collapses

答案C

解析本题考查动词辨析。句意：关于人的脑力是否会随着年龄的增长而衰退，科学家们现在有了一些令人惊讶的答案。reduces可以表示尺寸、数量、程度或强度的减少，词义引申之后，可以表示地位、处境、状况的降低；descends指缓慢或渐进的移动，多是从斜坡下降；declines指事物逐渐减缓、衰微或减弱；collapses指建筑物的倒塌，或因病而晕倒。根据句子语境和句意，大脑应该是慢慢衰弱，故本题选C。
