nolonger意思是“不再”
e.g.I’mnolongerastudent.我不再是个学生了。

了。)
not…anymore侧重侧重程度和数量
e.g.Youcandrinknomore.=Youcan’tdrinkanymore.

2.Thismethodisnotonlycruel,butalsoharmfultotheenvironment.
这种方法不但残忍而且对环境有害。

她不仅很会演奏,而且还会作曲。
2)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.Notonlyhadthepoormanbeenfined,butalsohehadbeensenttoprison.

3.Sharksareatthetopofthefoodchainintheocean’secosystem.

Heshoutedatthetopofhisvoiceinorderthathemightbeheard.
他尽力大声叫喊,以便别人能听见。
4.Iftheirnumbersdroptoolow,itwillbringdangertoalloceanlife.
如果它们的数目降至过低,会给所有海洋生物带来危险。
此句复数形式的number表达全海洋中鲨鱼的总量。当表示数值的高或低时,number要用high或low修饰。
e.g.Inthatcountry,thenumberofchildrengoingtoschoolishigherincitiesthanintownsandvillage.
在那个国家,城市儿童入学人数比乡镇及农村要高。

5.Environmentprotectiongroupsaroundtheworld,suchasWildAidandtheWWF,areteachingthepublicabout“finning”.
世界各地的环境保护组织,如野生救援协会和世界自然基金会,都在教育公众有关“猎翅”的行为。
1)句中fin本为名词,指“鱼鳍”。此句中的finning由动词化的fin(割鲨鱼鳍以获取鱼翅)的-ing形式转化而成,指课文中所陈述的“猎翅”这一行为。
2)WildAid和WWF组织
WildAid(美国野生救援协会)是保护野生动物及栖息地环境的一个非盈利性的机构,1999年注册成立,其宗旨是保护及救助世界范围内的野生动物;WWF(世界自然基金会)英文全称为WorldWideFundforNature,成立于1961年,是享有国际盛誉,全球最大的独立性非政府环境保护组织之一。

我阿姨不仅在学校教书而且还给报纸写稿。
