5．which ／as引导的特种定语从句 which／as可引导修饰整个主句或主句的一部分的定语从句，我们称这类定语从句为特种定语从句。在四级考试中，常测试考生正确选用这类定语从句的引导词的能力。 要提高解这类题的能力，考生应掌握 which与as的下列异同点。
（1）它们均可用于为主系表或主谓句型的定语从句中作主语。如：He married her，as／which was natural．
（2）它们均可用于为主系表句型的定语从句中作表语。如：He seemed a foreigner，as／which in fact he was．
（3）它们均可用于为主谓宾句型的定语从句中作宾语。如：I was very useful to him，which ／as he realized．
（4）在为主谓宾句型的定语从句中作主语时，通常用which而不用as。如：He saw the girl，which ／as de- lighted him．
（5）as引导此类定语从句时，常表示"正如……之意。因而，定语从句在意义上不可与主句相悖，且常为肯定句，而which则不受此限。如：She was married again， which ／as was unexpected．
（6）as引导的定语从句位置比较灵活，可位于句首，句中或句末。which引导的定语从句位置比较固定，一般位于句末。如：
As ／Which he realized，I was very helpful to him．请观察下列各题：
1）Prisons in some countries are short of staff， _____means each prison officer is overworked and underpaid．（CET-4，Sample）
