一些空洞的单词或词组根本不能为句子带来任何相关的或重要的信息，完全可以被删掉。比如下面的句子：

When all things are considered ， young adults of today live more satisfying lives than those of their parents， in my opinion.

这句话当中的“ when all things are considered ”和“ in my opinion “都显得多余。完全可以去掉。改为：

Young adults of today live more satisfying lives than their parents.
