and不可以换为as well as,as well as只是一个修饰语,其使mass mailings与前两项的并列关系改变为从属结构,而且并没有A, B, as well as C的结构;the use of表达wordy;
as well as mass maillings可以直接划掉。这样的话后面的意思就不对了
another way to figure out that this is wrong is to realize that "as well as ..." is a MODIFIER, and thus can be stricken from the sentence without affecting the surrounding grammar. that's problematic: if you strike "as well as mass mailings" from (d), you get remaining words that clearly don't work. remember: "as well as" is NOT a replacement for "and".
finally, the easiest way to kill (d) is to note that the construction "X, Y, as well as Z" simply doesn't exist. the only way to properly string three items in a list is "X, Y, and Z".
D. By using错误同C;and不可以换为as well as,as well as只是一个修饰语,其使mass mailings与前两项的并列关系改变为从属结构,而且并没有A, B, as well as C的结构;the use of表达wordy;用了convinced一般过去时表示convinced发生在has organized之前,逻辑含义不合理。
and不能用as well as 代替,没有A, B, as well as C的结构,另外,as well as是一个modifier,去掉该成分,句子 意思不变。
by the use of成了orgnize的方式状语,不对
