Question

1,为什么不用having been created 2,为何 不用 that
1,our modern civilization must not be thought of as< being created> in a short period of time
2,Ford proposed a system< in which> each worker would have a special job

Answer 1

1,our modern civilization must not be thought of as< being created> in a short period of time
being created是动名词做介词as的宾语,只表示一般的情况,所以不用完成时态.think of,as
2,Ford proposed a system< in which> each worker would have a special job
in which引导定语从句,先行词在从句中做地点状语,所以用介词加上关系代词或一个关系副词引导.in which =where而that是代词不能做状语.
