　　_________

　　given与giventhat在意义上没有多大区别,所差在於用法.

　　它们的定义视上下文而定.大致上有如果考虑到.就所知.而论.

　　e.g.givenhisage,就他的年纪来说,.

　　e.g.giventhecircumstances,如果考虑到各种情况,.

　　1.Given为介词,所以后面须接名词或名词片语.

　　就此定义,本人没有看过,其后加动名词.你在哪里看过吗?

　　e.g.Givenhisage,…..

　　Given为介词.hisage为名词片语.

　　2.Given+thatclause,mainclause

　　Given+that引导的从属子句,后接主要子句.

　　e.g.Given(thefact)thattheearthquakehasdamagedseverely,westilltrytoenabletheevacueestobeasindependentaspossible.

　　Given+thatclause

　　thatclause(that引导的从属子句)

　　=thattheearthquakehasdamagedseverely

　　mainclause(主要子句)

　　=westilltrytoenabletheevacueestobeasindependentaspossible.

　　e.g.Given(thefact)thatordinarypeoplearebombardedbyalldifferentkindsofads,selectingasuitableproductisnotthateasy.

　　Given+thatclause

　　thatclause(that引导的从属子句)

　　=thatordinarypeoplearebombardedbyalldifferentkindsofads

　　mainclause(主要子句)

　　=selectingasuitableproductisnotthateasy
