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

A is written B was written

難道該句子只可以用被動態的過去時？有無可可以用一般目前時來被動表示“客觀的知識，還有正常的狀態的意思？

當用一般目前時的時候，句子就不是被動語態了，而是系表結構。

大家可以說：

The play is written by a well-known playwriter.系表結構

但不會說：

A well-known playwriter writes the play. 主動語態

寫一個劇本這個事件不可能在說話時發生并結束。
