[size=13.63636302948px] 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.
[size=13.63636302948px]A. the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid
[size=13.63636302948px]B. forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
[size=13.63636302948px]C. having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid
[size=13.63636302948px]D. to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
[size=13.63636302948px]E. that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid
这道题D选项，经过抽取句子主干------to form， and to lay 有没有问题？ 我觉得应该是 to form and to lay，也就是说bricks后面不加逗号。
先谢谢~
