in one-s opinion

In my opinion, the density of Perl 5's regular expressions is one of the reasons why the language is so powerful, while at the same time fairly hard to maintain.

我认为，Perl 5的正则表达式的晦涩，也正是这门语言如此强大的原因之一，尽管它同时还相当难以维护。

In many important U. s. Supreme Court cases, there is one majority opinion accompanied by several concurring and dissenting opinions.

在美国最高法院的许多重要案件中，一个多数人意见往往与赞同判决但理由有异的意见和异议相并存。

In my opinion, one of the main reasons for causing such a situation is everyone "s different reference objects."

笔者认为，造成这种情况的重要原因之一，便是大家所持之参照系不尽一致。
