◎用法总结:notonly...but(also)表达的意思是“不但……而且……”,主要用于连接两个对等的成分;若连接的两个成分作主语,其后谓语动词与靠近的主语保持一致,即“就近原则”。如:NotonlyTombutyouareagoodstudent.不仅Tom,还有你也是个好学生。注意:notonly...butalso...中的also通常可以省略,或换成too,aswell(要置于句末)。如:Henotonlywashedthecar,butpolishedittoo/aswell.他不仅冲洗汽车,而且还擦拭了它。对点自测用括号内单词的正确形式填空1.Notonlythestudentsbutalsotheirteacher(be)interestedinthestory.

3.NotonlyyoubutalsoI(like)eatingicecreamverymuchnow.

【答案】1.is/was2.likes3.like[命题点二]Theymustgiveupsmokingassoonaspossible.他们必须尽快戒烟。

◎用法总结:as...aspossible意为“尽可能……,愈……愈好”,也可以说成“as...asonecan”。可根据需要,在两个as之间使用不同的形容词或副词。如:Cutexpensesasmuchaspossible.尽量减少开支。Wehavetor
