【答案解析】Love is considered as a permanent theme of literary works. In Eastern and Western cultures there have emerged many great works that use love as their themes. A Dream of Red Manshion by Cao Xueqin, a great classical novelist in China, and Romeo and Juliet by William Shakespeare, the "Father of English Literature", are both literary works that use love as their themes. At the end of the 18th century Cao Xueqin finished writing A Dream of Red Manshion while Shakespeare's works did not come into China until at the beginning of the 20th century. Shakespeare lived in England between the 16th and the 17th century. Therefore, Cao Xueqin's A Dream of Red Manshion was not affected by Romeo and Juliet. Shakespeare lived in England between the 16th and the 17th century, so he had no opportunity to read A Dream of Red Manshion. However, there is a great deal in common in the works of the two literary giants who lived in different centuries and in different cultural backgrounds.
