OG12 SC11

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,0
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
(C)    having bricks formed from mud or clay, and,
after some preliminary air drying or sun drying,
they were laid
(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
Parallelism; Verb form  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 fit 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 toform 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.
The correct answer is D.


这一题的平行OG上说是to build决定了to form，可是在has been 后面加上to do 是怎么得出的呢？念着很不顺啊...

the way后面常跟to do做补足语，所以也就比较常见的是用to do来作为the way的具体内容，例如，the way to get success of GMAT is to practice everyday and to fix mistakes effectively. 在这一题中，划线部分其实就是作为the way的具体内容，所以你要优先考虑用to do的形式。而且，你也可以用排除法，A错在they are laid缺乏连接词，B错在forming and to lay them并列结构错，C错误同A，D应该很容易排出了，意思混乱。

希望能帮到你
