418. Now, it is generally accepted that no college or university can finish educating its students by the time they graduate.

译文　现在，人们普遍认为没有一所大学能够在学生毕业的时候教给他们所有的知识。

点睛　本句利用主语从句避免了人称做句子主语，类似的用法还有it is widely/commonly/generally/universally believed/accepted/held/thought/acknowledged that...。by the time在此处意为“在……之前”，如：

By the time our teacher came in, we had started speaking English. 在老师进来之前，我们都已经开始讲英语了。

除此之外，by the time还有“这时候，在此时”的意思，相当于at the/that time，如：

By the time he had lost contact with the Party. 这时他已和党失去联系。
