1）绝对错误，and 的平行

and 平行结构要求一致

The purpose of the sentence is to describe the historically most popular method of building walls. The first clause announces this topic and the second clause describes the particular method. The clearest, most efficient way to accomplish these two pieces of business is to use a parallel structure.The ways to build in the first clause is narrowed to the single way to form and to lay in the second clause. There is no need to alternate the verb phrases between active and passive voice or to shift tenses.
A. The active gerund phrase the forming of bricks does not fi t with the passive verb phrase that follows (they are laid).
B. The verb phrases forming the mud … and to lay them are not parallel.
C. In addition to faulty parallelism between having bricks formed and they were laid, the tense in the second half of the sentence unaccountably shifts from present to past.
D.Correct. The phrases to form and to lay in the second clause are parallel to to build in the first clause.
E. The relative clause beginning with which apparently (but nonsensically) describes the closest nouns, mud or clay, rather than bricks.

1. 逻辑语义错误
有几种砌墙的方法， 但是最广泛应用的方法是 砖的形成
砖的形成不是 砌墙的方法

and前后结构平行
to form...and to lay...

，but后面的句子，想表达最为广泛使用的造墙法包括两个步骤，第一步，制作砖块，第二步，砌砖进墙，所以语义上这两个动作应该是平行的

and 平行

they are laid 和the most extensively used method 结构平行了

看到and首先想到题目考平行结构 其次to do不定式可以做表语

and 前后用法一致
