Stay awake! You should know that it ________ to sleep in class.
A．doesn’t permit
B．is not permitted
C．will not be permitted
D．was not permitted
题型：单选题难度：中档来源：不详
答案
B
试题分析：句意：保持清醒，你应该知道在课堂上是不允许睡觉的。这里it是形式主语，to sleep in class是真正的主语，根据Stay awake可知说的现在不能睡觉，所以应该用现在时故选B。 点评：本题难度适中。动词时态及语态是高中阶段的重难点之一，高中要求掌握的时态需要考生牢记它们的用法，但是时态必须要结合一定的语境才能做出正确的判断。 即学即练：--- I hear you _______ at Smith’s. --- Yes, I________there for about three months. A．work; had been working B．worked; was working C．are working; have been working D．worked; have worked 解析：C。句意：---我听说你在史密斯那里工作。---是的，我一直在那里工作了3个月。
