18、those ----variations。far greater------ than 。
是少了，若真是这样：those the same species在语法上是不通的。中间应该有among。
35、调整后的语序才正常。其他的选项包含着结构、语法的错误不谈。单看A--原句。depending on mass放在这里非常突兀。这个选项C，说实话，我是读出来的。
10、(A) Contrary to：与。。相反，比较加转折。我选它。
(B) In contrast with ：比较，但两者无可比性。
(C) Opposite of ：不知道为什么，就是不想选它。
(D) Unlike ：比较，但无可比性。
(E) In spite of ： 尽管，逻辑上不通。

2、as a group 是修饰his letters 的。
6、我选C。the most intense since Camille in 1969。since--自从。。。，从句有省略。
15、为什么放到中间，不知道。但用完成时态，肯定是对的。more than doubled 已经足已说明问题，加increase多余。
7、Judge Lois Forer's study（主语） asks（谓语）[ why some litigants have a preferred status over others in the use of a public resource,]（宾语）[ the
courts, which in theory are available to all but in fact are unequally distributed between]补充说明a public resource

6.选C。since从句是典型的省略形式，补全了应该是since Camille approached the Atlantic coast in 1969.
15. has since...的用法是正规的书面语用法，Times上很多文章中可以查到，相当于句子末尾的since then，更但简洁，而且修饰作用一目了然。

makai：你对15题的解释，我非常佩服！
