问题
It seems oil______from this pipe for some time. We’ll have to take the machine apart to put it right.
选项
A、had leaked
B、is leaking
C、leaked
D、has been leaking
答案
D
解析
此题测试的是时态。现在完成进行时是指动作到目前为止,并且还将延续下去的状况,如本句。首先,句中有时间状语for some time,这是典型的完成时态标志,据此排除B和C。A项是过去完成时,表示到过去某一时刻已发生的情况,而句子说的是现在的情况,所以A也是错的。句意为:油好像从这个管子里漏出一段时间了,我们得把机器拆开再把管子装好。
