语法综合:使用in case的两点特别注意

来源:互联网发布时间:2008-12-26 浏览:1622次

in case in case of性质不同

in case 可用作连词和副词,而in case of 用作介词。如:

In case of fire, ring the bell. 如发生火灾,请按铃。

The wall was built along the river in case of floods. 沿江筑了堤坝以防有洪水。

有时两者可以互相转换。如:

In case I’m not here, ask my brother to help you.=In case of my not being here, ask my brother to help you. 如果我不在,可让我弟弟帮助你。

in caseif有时意思不同

注意下面两个句子在意思上的不同:

I’ll come tomorrow in case Ann wants me. 明天我要来,以备安找我。

I’ll come tomorrow if Ann wants me. 如果安找我,我明天就来。

但是,介词短语 in case of… if there is…的意思却相同。如:

In case of accident phone 999.=If there is an accident phone 999. 如果发生事故,请拨电话999
