请教一个问题:上面的if从句可以没有谓语动词吗,如果想要在作文中,运用类似语句来使得句子不那么普通,有哪些基本的用法和规则。
句子出处:If its message were confined merely to information-and that in itself would be difficult if not impossible to achieve, for even a detail such as the choice of the colour of a shirt is subtly
网友提问时应该提供完整的句子,不应该自己随意断句,这会影响对句子意义和逻辑的判断。原句如下:
If its message were confined merely to information — and that in itself would be difficult if not impossible to achieve, for even a detail such as the choice of the colour of a shirt is subtly persuasive — advertising would be so boring that no one would pay any attention.
如果广告仅限于提供信息——就其本身而言,即使可能,也将非常困难,因为即使是像衬衫颜色的选择这样的细节也是非常具有诱导性的——那么,广告将会变得让人厌烦而不再注意它。 整个句子是一个虚拟条件句,表示与现在事实相反的假设,从句用were,主句用would be. 二个破折号相当于括号,其中的内容是对if从句的补充说明。 if not impossible为插入语,表示让步条意义,通常前后应该用逗号隔开。意为”即使不是不可能“、”即使可能“。 类似的插入语还有: if possible if any if anything if not 你可以研究一下词典例句,体会这些惯用语的使用场合。在没有完全掌握其使用的条件之前不宜滥用,否则会弄巧成拙。 |
