This year we are determined to end poverty as scheduled. 

Premier Li Keqiang said on Thursday he hopes and believes that the commitment made by leaders of 15 countries at leaders' meetings on East Asia cooperation last year on signing the Regional Comprehensive Economic Partnership by the end of this year will happen as scheduled.

第一问：两个 as scheduled，是 as is scheduled 的省略说法。按传统语法，这个结构视为“as 引导的非限制性定语从句”，as 指代前文整个主句，且作了从句的主语。按现代语法，该结构属于“比较从句” 中的方式从句，as 为“比较连词”。我认为，类似这种 as + 过去分词 结构，不要细分，最好看作固定搭配，在句中作“方式状语”。

关于省略问题，我给你解答过了，没看见吗？

第二问：Such people as were recommended by him were professors of the university.

这个句子，按照传统语法分析，as were recommended 是定语从句，先行词前有such，the same 等修饰时，关系代词用 as 引导。定语从句应完整，不可随意省略成分。

一个是固定说法的“方式状语”，一个是“定语从句”，所以，前者可省略 be，后者不可。
