ＯＧ２０７

207. In the textbook publishing business, the second quarter is historically weak, because revenues are low and marketing expenses are high as companies prepare for the coming school year.

a    low and marketing expenses are high as companies prepare
b   low and their marketing expenses are high as they prepare
c   low with higher marketing expenses in preparation
d    low, while marketing expenses are higher to prepare
e    low, while their marketing expenses are higher in preparation
请问答案Ａ中的ＡＳ　是什么意思，怎么试图翻译，可就是说不同呀～！

另一个问题是：不是两个独立的句子要是用ＡＮＤ　连接的话不是之前要加逗号的吗？否则不就是ＲＵＮ－ＯＮ　ＳＥＮＴＥＮＣＥ吗？那么本句怎么就对了？

谢了，ＲＯＧＥＲＺＨＵ

那谁来回答一下第２个问题？？？？？？？？？？？？

because revenues are low and marketing expenses are high as companies prepare for the coming school year 其实在and 后省略了because

because revenues are low and (because) marketing expenses are high as companies prepare for the coming school year 这样一来就很清楚,and前后是两个并列的短语, 而非句子.

啊？ＢＥＣＡＵＳＥ怎么成了短语了？我还是不太能接受你的解释～！

谁能再进一步解释一下什么是ＲＵＮ－ＯＮ错误？为什么它是错误的？　

because是因果关系从句的引导词，两个从句用and并列想得通吧？SVO and SVO肯定是错的，但举个例子That I am a fool and that I am a pig are fallacious remarks. 两个主语从句的并列。To conclude, 从句是可以用and并列的。

这下子完全懂了～！谢谢ＴＯＮＹＡＤＩＤＡＳ　和ＬＡＶＥＮＤＡＲ～！
