选择题
A giant of a man was standing in the doorway. His face was almost completely hidden by a long and untidy hair and a wild beard, but you ______ make out his eyes, shining like black beetles under all the hair.
A．might
B．could
C．should
D．would
答案
答案：B
题目分析：这里表示但是你能够辨认出他的眼睛，在头发下像黑色的甲壳虫一样闪闪发光。表示过去的能力，用could。
点评：情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语。
