问题 The product demonstrations lasted______about 2 hours, and they seemed to be a great success.

选项 A、for
B、during
C、since
D、from

答案 A

解析只要知道demonstration和last的含义，很容易就能找到该题答案。在这里product demonstration是“产品演示”之意，last是“持续”的意思。要想表示“演示会持续了两个小时”的意思，最适合的词是表示时间持续状态的前置词for。(B)的during像during the week(在整个一周期间)一样，主要是在表示特定期间的时候使用。
