短语的用法
1. as supposed to按照……用法：as supposed to是as it was(is) supposed to的省略形式，是为了避免重复。
例句1：Although the factory director is not in, all the workers should do as supposed to.
虽然厂长不在，但是所有的工人都应该做自己份内的事。
结构分析：although与though用法相近，都引导让步状语从句。Although引导状语从句，the factory director是主语，is not in是系表型谓语（is not系动词+ in表语）, all the workers是主语（all the是两个前置定语）， should do是谓语，as (it is) supposed to是状语从句。
2. as compared to(with)与……相比
用法：as compared to在句中一般用作状语。
例句1：Large enterprises are the main source of national tax as compared to medium and small enterprises.
与中小企业相比，大企业才是国家税收的主要来源。
结构分析：Large enterprises是主语，are the main source of national tax是系表型谓语（系动词are+表语the main source of national tax），as compared to medium and small enterprises是状语从句。
