有Such as to ...那有没有such...as to呢 它和和such as to...有什么区别?
此外such...as to与such...that又有什么区别?
能不能帮我找些例题说下它们几个
一、such 有两种词性:名词性的不定代词和形容词.正是由于词性不同,所以在表示“如此...以致于” 这种意思时就出现了两种不同的结构.
1. such as to ... 中的 such 属于不定代词,指代上文提到过的人或事物,意思是“这样的人/如此的事物”,如:
* The case has been such as to prove true. 情况已经如此,以致于证明是真实的.
* Their anxiety was such as for them not to be able to sleep. 他们如此焦虑,以致于难以入睡.
2. such ... as to ... 中的 such 属于形容词,需要放在名词前作定语,意思是“这样的/如此的...”,如:
* We are not such fools as to believe him. 我们不是那样的蠢人, 以致于能够相信他.
* She had such a fright as to faint. 她如此吃惊以致于吓得昏了过去.
二、Such as to 和 such...as to 中,如果把不定式加上主语改为结果状语从句,就变成了 such that ... 和 such ... that .以下就是上面句子改写成的从句:
* The case has been such that it can prove true. 情况已经如此,以致于(情况)证明是真实的.
* Their anxiety was such that they could not sleep. 他们如此焦虑,以致于(他们)难以入睡.
* We are not such fools that we can believe him. 我们不是那样的蠢人, 以致于(我们)能够相信他.
* She had such a fright that she fainted. 她如此吃惊以致于(她)吓得昏了过去.
