[求助]2个句子的语法理解

1 Absent evidence that this is the case, it is equally possible that adopting the program would not suffice itself.  

请问前半句Absent evidence that this is the case "that"后引导的是什么句子做什么成分?that后是完整的句子,不是定语从局.名词性从句的话,又不是主语从句或者同位语. 也不象是状语从句. 实在有点困惑.

2 The ad's claim unfairly infers from United's comparatively strong safety record in the past that United's new truck this year must also be comparatively safe.

此句是不是倒装,正确顺序是否是The ad's claim unfairly infers that United's new truck this year must also be comparatively safe from United's comparatively strong safety record in the past .读的时候不清楚infer 连的是infer from还是跟that 从句.

两个句子是在读官方范文时看到的,想问下语法,就pose在这个forum 里..望XDJM帮忙..

   顶一下.. 顶一下..

1、Absent evidence that this is the case，that从句引导的是同位语从句，修饰evidence，意思是缺少可以"使事成事"的evidence。后面的it is equally possible that adopting the program would not suffice itself.中itself是指program.也即说缺少证据，采取该program可能无法suffice.

2、你的想法是对的.
