Tom spent half an hour working out this problem. It __Tom half an hour ___out this problem.
解题思路： spend time ／ money (in) doing sth. 花费时间（金钱）做某事。 It takes sb. ＋时间＋to do sth. 做某事花了某人多少时间。 因为原题干所用时态是一般过去时，所以第二个句子的谓语动词要变成过去式。
解题过程：
Tom spent half an hour working out this problem.
It took Tom half an hour to work out this problem.
句意是“汤姆花费半个小时解答这个问题。
最终答案：略
