The L-shaped rear light clusters again reflect the typical look of a BMW and provide that unmistakable night design.

L形的尾灯群再次反映了宝马典型的外观和明确无误的规定，晚上设计。

The first two chapters showcase the Anti-Rightist Campaign (1957) and "the Great Leap Forward"(1958). Based on the works of Poetry and the poems relevant to the two said political campaigns, these two chapters analyze the ways in which the poems assembled, cohered and acquired referentiality intra-textually and in a wider cultural context. Changes in that formative process provide an effective frame of reference for us to reflect on the losses and gains of the Poetry and socialist literature in a particular time.

前两章分别选择1957年下半年的"反右派"和1958年的大跃进这两个典型的运动，根据《诗刊》与这两个运动有关的作品来分析文本与文本群、文本类型在自身内部以及在更大的文化语境中聚集、凝结和获取现实指涉力的方式，其中的变化过程为我们思考和总结一个刊物和一个阶段的社会主义文艺的特点和得失提供一个有效的观察点。
