谁能帮我分析一下下面这个句型?
One common reason for all this is that no effort at all has been spent on tuning the database,only on object-orientation purity.
主语:one common reason for all this
系动词:is
标语从句:that no effort at all has been spent on tuning the database,only on object-orientation purity
然后把标语从句再分裂:分句主语---no effort at all; 谓语---has been spent ; 状语----on tuning the batabase,only on object-orientation purity
翻译:所有这些的一个共因就是仅在object-orientation purity上,根本没有在数据库调音时付出一点努力.
这些专业词汇只能由你自己翻啦,请恕才学熟浅
