or引导的同位语

or引导的同位语一般可分为释义性同位语和修正性同位语两类。
一、释义性同位语对前一同位成分加以解释,但有时也只是前一同位
成分的另一个称法或术语;但不论是哪一种情况,前后两个同位成分在意义上是相同的。例如:
1.The species that accepts electrons.in an
oxidation.reduction reaction sometimes is referred to,as the
oxidizing agent,because it is the species that is responsible for
the oxidation,or t.he loss of electrons
2.The load at which a material starts behaving in a.clearly plastic fashion is called its yield load or yield point.
使材料开始出现明显塑性变形的荷载称为屈服荷载或称屈服点.
3.The next group of organisms in order of increasing
complexity is the higher bacteria,
在渐次复杂的生物序列中,下一组是更为高级的菌类,或称放线菌属,它介于普通细菌和较高级的真菌之间。
二、修正性同位语对前一同位成分加以修改或限定,前后两个同位成分在意义上不完全相同。例如:
1.There isn‘t any established theory,or even a generally believed one about how people store and retrieve information when they need it.
对人们如何储存信息以及必要时如何检索信息,目前还没有任何已经确立的理论,甚至还没有一种普遍相信的理论。
[句中后一同位成分对前一同位成分的否定范围作了扩大。]
2.They are enjoying.themselves,or at least they appear to be enjoying themselves.
他们过得很愉快,至少看起来是如此。
[句中后一同位成分对前一同位成分的陈述略作了修正。]
