句子结构：…, astronomershave detected… planets, … as large as Jupiter, circling…
SVO，doing不是doing只有两种情况么，一个结果壮语一个伴随状语。这题里面怎么就出现了变成后置定语了，
133. (31602-!-item-!-188;#058&004586)
In the past several years, astronomershave detected more than 80 massive planets, most of them
as large or larger than Jupiter, whichcircle other stars.
(A) most of them as large or larger thanJupiter, which circle
(B) most of them as large or larger thanJupiter and circling
(C) most of them at least as large asJupiter, circling
(D) mostly at least as large as Jupiter,which circle
(E) mostly as large or larger thanJupiter, circling
句子结构：…, astronomershave detected… planets, … as large as Jupiter, circling…
主语是astronomers，谓语是have detected，宾语是planets，后跟比较结构插入语，现在分词circling
比较，A as… as… oradj.er than B; A at least as adj.er asB。常见的错误用法包括：A as… or adj.er
than B（少 as）; as…as comparedto; as… than compared to; as… than 等。
平行对称，注意连词 and 的前后是否有合理且符合原句意思的平行对象。
(B) 缺少第二个as，as…as…是完整结构；and circling没有并列对象。
(C) 正确，them指代planets，现在分词circling作后置定语修饰planets，前面most of them…是插入
(D) mostly是副词，修饰错误。(E) mostly是副词，修饰错误；缺少第二个as，as…as…是完整结构。
后置定语不是应该紧跟修饰词不加逗号么？？？求解~~~
