In the past several years, astronomers have detected more than 80 massive planets, most of them

as large or larger than Jupiter, which circle other stars.

(A) most of them as large or larger than Jupiter, which circle

(B) most of them as large or larger than Jupiter and circling

(C) most of them at least as large as Jupiter, circling

(D) mostly at least as large as Jupiter, which circle

(E) mostly as large or larger than Jupiter, circling


答案选C，可是为什么这里的them不存在指代不清的问题呢，不能指astronomers吗

因为这个的主要考点是“as large as or larger than”和“at least as large as ”这个“大于等于”的考点。然后就只剩下CD选项了。D选项明显能看出不对。而且抛去语法，看句子意思的话，也能明显知道这个“they”不是指天文学家呢。我觉得做语法，首先是读取题目的关键信息，然后对各选项进行评价，排除掉基本不会对的选项，然后把正确概率较大的选项进行比较，从它们的差异中以一定的偏好，选取一个正确概率最大的选项。
