单项选择题
Written, ______ , in an easy style, the book is suitable for beginners.
A.as it was
B.as it does
C.as it is
D.as it has been
答案
参考答案:C
解析:过去分词+as it is(was)表示原因。这是一种强调语气的表示“原因”的结构。written, as it is, in an easy style相当于as it is written in an easy style。又如:This article, published as it was, in a small local magazine, remained unknown for a long time. 这篇文章由于发表在一个地方小杂志上,所以长时间没有人知道。这个句子是一般现在时,所以不能选A。
