标题: OG12 11

11. There are several ways to build solid walls using just

mud or clay, but the most extensively used method

has been the forming of bricks out of mud or clay,

and, after some preliminary air drying or sun drying,

they are laid in the wall in mud mortar.

(A) the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid

(B) forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them

(D) to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them

(E) that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid

答案是D
我想问的是and前面的逗号
在这道题里to form 和to lay 这两个成分的平行
但是我只知道平行两个以上成分时and前加逗号，平行两个成分时and前没有逗号
请问这个逗号该怎么解释~~~？

逗号是为了把 “after some preliminary air drying or sun drying” 分离出来啊

after some preliminary air drying or sun drying作为插入语那应该是and后面逗号的作用吧？
我想问的是and前为什么有个逗号 ",and" 不是应该接的是句子吗？
