—What's the matter with you?You look so pale.— I didn't get to sleep last night.I ______for my maths test all night.
A)study B)studied C)have studied D)had studied
答
B
答
B
昨晚我为准备数学考试学了一夜。表示过去的动词，所以用过去。注意，一般过去时也是过去完成的动作，所以，在这里不能用过去完成时
答
B 由于讲述过去的事情,故排除A和C（都表示现在）；had studied用于过去的过去,而本句中并没有一个过去的动作与study作比较,故用一般过去时.
