◎用法總結:notonly...but(also)表達的意思是“不但……而且……”,主要用于連接兩個對等的成分;若連接的兩個成分作主語,其后謂語動詞與靠近的主語保持一致,即“就近原則”。如:NotonlyTombutyouareagoodstudent.不僅Tom,還有你也是個好學生。注意:notonly...butalso...中的also通常可以省略,或換成too,aswell(要置于句末)。如:Henotonlywashedthecar,butpolishedittoo/aswell.他不僅沖洗汽車,而且還擦拭了它。對點自測用括號內單詞的正確形式填空1.Notonlythestudentsbutalsotheirteacher(be)interestedinthestory.

【答案】1.is/was2.likes3.like[命題點二]Theymustgiveupsmokingassoonaspossible.他們必須盡快戒煙。

◎用法總結:as...aspossible意為“盡可能……,愈……愈好”,也可以說成“as...asonecan”?？筛鶕枰?在兩個as之間使用不同的形容詞或副詞。如:Cutexpensesasmuchaspossible.盡量減少開支。Wehavetor
