verbal 71 求解呀！！！！

71. Analysts blamed May's sluggish retail sales on
unexcitingmerchandise aswell as the weather, colder
and wetter than was usual in some regions , which
slowed sales of barbecue grills and lawn furniture .
(A) colder and wetter than was usual in some
regions, which slowed                               which错误，这种格式修饰regions，如需修饰weather，需改成“that”；than was ususal 不好，was没有必要，同时was时态有问题
(b) which was colder and wetter than usual in some
regions, slowing                                         correct, slowing结果状语
(C) since it was colder and wetter than usually in
some regions, which slowed                    which错误同A， than usually错误，since用法奇怪，改变句意
(D) being colder and wetter than usually in some
regions, slowing                                       being错误， uaually错误，slowing这里不知道修饰谁
(E) having been colder and wetter than was usual in
some regions and slowed                         having been错误，than was usual 错误，and slowed平行错误
答案：b
这道题我选错了，后来看了好久，现在似乎想明白了，大神们看看我这样分析的对不对，这里which引导的是weather的同位语从句，而后面的slowing。。。是修饰weather的，虽然我们说不能出现修饰部分的重叠，但是中间有同位语的可以例外，这样对吗，
