Over the centuries, further trading allowed more exploration of the regions to the west of China, as recorded in Du Huan’s Record of My Travels in the eighth century. (Para. 2)
上句中as recorded似乎不完整，但as的这种用法其实是一种省略现象。
以下两种解释都可接受：
第一,把as看作关系代词, 指代后面整个主句的内容, as是定语从句的主语,后面省略了is。因此,as recorded等于as is already recorded。
第二, 把as看作从属连词,引导方式从句,意为“像……那样”,as之后省略了it is,it指代整个主句的内容。因此,as recoded等于as it is recorded。
能用于此句式的动词，一般都是“陈述、叙述、描述、提及、说及、显示、指出”之类的词，多用于议论文体，是带有总结性的提示语。
as already said 2. as already mentioned
3. as already described 4. as already discussed
5. as already noted 6. as already stated
7. as already announced 8. as already pointed out
9. as already indicated 10. as already hinted
11. as already told 12. as already shown
13. as already emphasised 14. as already observed
15. as already explained 16. as already suggested
