问两题语法，GWD

E中，that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid
which语法上就近指代mud or clay，但逻辑上应该是bricks，因为能够laid的是bricks，不是mud or clay.

D中them指代bricks，正确。
此外，D中，前面several ways to build solid walls与后面的to form the mud or clay into bricks, 以及 to lay them构成了平行结构（都是to）。（这个好难看出来。俺也是看了语法解释后才发现的。）

询问语法题两道

17. Several financial officers of the company spoke on condition that they not be named in the press reports.

A.    that they not be named
B.    that their names will not be used
C.    that their names are not used
D.    of not having their names
E.    of not naming them

on condition that是idiom，所以DE排
然后这个词汇是表示虚拟的，所以BC的will not/are not就不对了

 Answer:
GWD上答案是A，但是别的书上不是的，所以不知道到底哪个对。
