选择题
--They ________ out the problem, but failed.
--What a shame ! I never thought it was going to happen like that.
A．managed to work
B．managed working
C．sought working
D．sought to work
答案
答案：D
题中的sought为seek的过去式，与它构成的短语为seek to do 试图做某事，根据第一句话的后半句but failed，可排除A选项，因为manage to do 意为设法做成某事，B、C搭配不对，所以选D。第一句句意为他们试图解决这个问题，但是失败了。
