Question

It is said that the early European playing-cards ________ for entertainment and education．

[　　]

A．

were being designed

B．

have designed

C．

have been designed

D．

were designed

Answer 1

答案：D
解析：

　　思路分析：此题考查动词的时态和语态,主语“早期欧洲人玩的扑克牌”与谓语动词“设计”是被动关系,讲的是过去的事情。

　　深化升华：在选项A和D之间要求区分一般过去时和过去进行时,一般过去时讲过去发生的事,时间范围较广;过去进行时指过去某一时刻所发生的动作。如I was doing my homework when somebody knocked at the door．此句话表示的是有人敲门的那一时刻我正在做作业。

提示：

此题乍一看,似乎是讲现在的事,因为It is said是一般现在时,但“据说”和“设计”是发生在不同时间的动词。
