重点句式
1.It has in fact become one of the most famous American poems of all time,not only because of its natural style, but also because of its thoughtful insights into human nature.
事实上,它已经成为有史以来最著名的美国诗歌之一,不仅因为它的自然风格,而且因为它对人性深思熟虑的洞察力。(教材p.9)
【句式剖析】本句是一个简单句,It has in fact become one of...是“主系表”结构,not only...but also....意为“不仅……而且……”,引导两个because of短语,在句中作原因状语。
Visiting this paper-cutting exhibition,we will not only enjoy the folk art works, but also learn a lot.
参观这次剪纸展览,我们不但能欣赏到民间艺术作品,而且能学到很多。
【句式拓展】
(1)not only...but also...用于连接两个表示并列关系的成分,着重强调后者,其中的also有时可以省略。
(2)not only...but also若连接的两个成分作主语,其谓语的单复数通常与靠近的主语保持一致。
(3)not only...but also若连接两个句子,且not only 位于句首时,not only 后面的句子要用部分倒装。

她不仅讲瑞典语,还讲英语和法语。

【句式剖析】When reading...是省略句,省略了从句的主语和连系动词,cannot help but do是固定句式,意为“不得不做某事;只得做某事”,but后面用动词原形。

对我来说,这实际上是多年以后当我来不及改变它们时,接受我们的选择所带来的后果。(教材p.10)
【句式剖析】本句是一个复合句。it is really about...是主句,when it is...是定语从句。too...to do sth意为“太……而不能……”,too后接形容词或副词,to是动词不定式符号,后接动词原形,动词不定式表示否定意义。

路太窄了,大型卡车过不去。

在以下几种情况,too...to...结构可以表示肯定意义,而不是否定意义:
(1)当不定式前有否定词修饰时。

(2)当副词too的前面有否定词修饰时。
