被动语态的时态问题

The Brief History of Time ___ by Steven Hawking. It is a great book about science.

A is written B was written

难道该句子只可以用被动态的过去时？有无可可以用一般目前时来被动表示“客观的知识，还有正常的状态的意思？

当用一般目前时的时候，句子就不是被动语态了，而是系表结构。

大家可以说：

The play is written by a well-known playwriter.系表结构

但不会说：

A well-known playwriter writes the play. 主动语态

写一个剧本这个事件不可能在说话时发生并结束。
