初中英语问题 为什么which produced were drawn 是错的？详细些！谢谢

The car produced in Germany in the 1960s looks old now.这个句子是对的，produced 是过去分词表被动，这里相当于形容词。。。。。。的，被生产的。
Some pictures drawn by the Africans.这个句子是错的，这是一个被动语态句子，被动语态的结构是be加过去分词，这个句子缺be动词，这个句子应是，Some pictures were drawn by the Africans.

which produced were drawn 这个不是完整句子. 你的原意是什么?

The car produced in Germany in the 1960s looks old now.
对的

Some pictures(drawn)by the Africans.
错的
some pictures were drawn by the Africans.

。
The car (which produced)in Germany in the 1960s looks old now. ——该句应为定语从句 缺乏了引导词
Some pictures( were drawn)by the Africans.——缺了谓语动词

应该是The car which was produced in Germany in the 1960s looks old now.
