1 They argue that what we have today is not a drug problem but a drug prohibition problem, (这里)that anti drug laws spawn more violent and crime than the drugs themselves.
2 They would find themselves unable to live without the drug, (这里)no longer able to work, go to school, or maintain personal relationships.
3(可能属另一类) Students who use drugs not only limit their own ability to learn, they also disrupt classrooms.
请问but also可以省略but吗?
如果提问者说一下出处,会更好回答。
搞这些东西应该没什么意思,它们有时是作者(指有文化的native speakers)个人偏好,有时是他们的临场发挥,有时是笔误。作为英语学习者,应该要有这种开放的心态。如果是作为出试卷的人,则不可能、也不可以在这种地方,不按最保守的样子来出试题。保守往往厚重,灵活往往会使问题活泼、与语境更为融洽。
回到这三个句子:
最常见结构是第一个that省略,第二个that需要,这两个that引导的分句,自然要and连接一下。 除非有A, B and C的结构,意思是,后面还有一个that分句,构成 (thatA)--, thatB-- ,and thatC--。 虽然这么说,第一个句子 也不见得错误。
句子2是标准结构。 ... unable ..., no longer... , or maintain ... (A, B and C)
以下这些变体都是可能的:not only... but also; not only... but sb also; not only... but (also) ; not only... (but) also <很可能在省略but后,also前面应该用“;”,但仍然可能用逗号>; not only... ; 如:She not only consults, she insults.” (Muriel Spark, Aiding and Abetting);..., but also.
如:It depends on your point of view, but also on where you live.”

此外,only也可换成just, 但意思会有所不同。
