I’mnolongerastudent.

我不再是个学生了。有两个短语和nolonger同义，即not…anylonger和not…anymore，但他们侧重的方面不同。Languagepointsnolonger和not…anylonger侧重时间。

e.g.Henolongerliveshere.=Hedoesn’tlivehereanylonger.

他不在这儿居住了。(一个时间以前他住在这儿，过了这个时间，他就离开了。)not…anymore侧重程度和数量e.g.Youcandrinknomore.=Youcan’tdrinkanymore.

你不能再喝了。(喝酒的量到了一定程度，不能再继续下去了。)2.Thismethodisnotonlycruel,butalso

harmfultotheenvironment.

这种方法不但残忍而且对环境有害。notonly…butalso…用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”;其中的also有时可以省略。e.g.Shenotonlyplayswell,butalsowritesmusic.

她不但很会演奏，而且还会作曲。

Notonlymenbutalsowomenwerechosen.

不仅仅是男的，女的也有被选中的。若连接两个成分作主语，其谓语通常与靠近的主语保持一致。e.g.Notonlyyoubutalsohehastoleave.

不只是你，他也得离开。

notonly放在句首，后接句子时要用倒装结构。e.g.Notonly

在那个国家，城市儿童入学人数比乡镇及农村要高。常与number搭配的动词有grow,fall等。e.g.Thenumber
